Purpose Virtual garment fit will be an important determinant for the online purchase decision of consumers in the near future. Therefore, the purpose of this study was to develop a conceptual model to explore the factors that might impact consumers' virtual garment fit satisfactions (VFS). Design/methodology/approach Virtual body satisfaction (VBS), acceptance of the virtual try-on technology and virtual fabric properties were examined as factors that would potentially impact consumers' VFS. Forty-five women, from 18 to 35 years old, were recruited for the study. Participants were scanned by using a 3D body scanner and their scans were used for virtual try-on. Seven circular skirts with different fabric properties were created by using a commercial 3D simulation software. Participants evaluated the fit of these virtual skirts on their own virtual bodies. Participants' VFSs and their correlations with VBSs, acceptance of virtual try-on technology and virtual fabric properties were analyzed by Pearson's correlation test. Findings Participants' VBSs at hips were correlated fairly good with their VFSs (r = 0.50,N= 180,p< 0.01) and their acceptance of virtual try-on technology was weakly correlated to VFSs (r = 0.24,N= 180,p< 0.01). However, no significant correlation was found between virtual fabric properties and participants' VFSs. Research limitations/implications This study did not examine the ideal beauty notion, which may affect consumers' expectations about how the garments should fit on them. Another limitation was the use of a single skirt design as a stimulus. Originality/value Studies that explore virtual garment fit often measure the garment ease or the virtual fabric tension and ignore consumer perspective, which is essential for online purchase decision. This study is unique as it prioritizes consumers' perspectives.

Purpose The purpose of this paper is to show the dyeing effect of banana peel on polyamide fabric by using various mordants and to reveal alternatives to metallic mordants. Design/methodology/approach The simultaneous mordanting method was used in the dyeing process. Findings From environmental and economical points of view, this paper studies the use of a natural waste product in textile dyeing. Assessment of domestic organic wastes will provide new possibilities for valorization of biomaterials. It is concluded that colorimetric data are affected by the amount of plant used in extraction, amount and type of mordant and pH of dye bath. Tin II chloride ensured the lightest color shades. No alternative mordants could be presented to iron II sulfate and tin II chloride, as they generated completely different color shades. Acids can be an alternative to 0.8 g/L alum mordant. Ammonium sulfate and sodium acetate also generated similar colors to alum. Ammonium sulfate can be substituted for citric acid and alum. Banana peel can be considered as a natural dye source for polyamide elastane blend fabric. Originality/value Banana peel can be suggested as a natural colorant with good wash fastness for dyeing of polyamide elastane blend fabric.

The purpose of this study is to develop a system that detects warp breakage in manual looms using simple mechanisms combined with electronic circuitry. Design/methodology/approach This study used the universal design methodology model where results from observations and interviews aided in designing the appropriate blueprints for the mechanism. Findings Testing procedures revealed that the conductivity of steel bars coupled with the weight of the droppers affected the efficiency of the mechanism. Additionally, the weight of the drop wires influenced the rising of the warp threads during shedding. Considering this, a plate thickness of 0.06 mm was ideal for the droppers which did not affect warp shedding. Test outcomes at the weaving shed proved the workability of the mechanism for timely or prompt repair of a broken warp by weavers that ensured fabric quality. Originality/value The issue of warp breaks remains a critical problem at weaving on manual looms which influence the quality of fabrics. These looms are used by craftsmen in producing interesting fabrics for the market of which they depend on for their living. Premise on this, a two-way (light + sound) alert system was developed to assist weavers to effectively locate and repair broken yarns. Additionally, weavers with special needs (blind people) would be notified on a warp break for immediate repair from someone. This would limit the unnecessary challenges associated with broken warp yarns during weaving.
Investigation was carried out on how the tensile and related properties of Siro yarns, spun from two separated rovings of different types of materials, were affected by the twist factor and draft. Comparison on Siro yarns and two-fold yarns of the same linear density and twist factor revealed that the former was better in tensile strength and related properties. The Siro yarns are believed to be able to bear extra tension during manufacturing processes such as weaving and knitting.
This paper presents the study of structures of random fibre arrangement with very high irregularity and textiles made of fibres with a very high level of parallelism, arranged in layers. Studying of textile materials by the proposed aerodynamic method, namely, the gas filtration modeling, enables the differentiation of their internal structure. Therefore, it can be applied to modern analysis and comparison of use characteristics of any textiles. Gas filtration modeling consists of blowing an air stream through a textile sample of a porous structure. The flow is ruled by Darcy’s law and Poieuille’a-Hagen’s law and by mass, momentum and energy conservation laws. The theoretical model of studies assumes dividing the sample thickness into layers in which, on the basis of pressure Δpi and mass flux m measurements, we calculate: dk-diameter of ducts; f-specific surface, Ki-Darcy coefficient, Rei, Eui, Dai Reynolds, Euler and Darcy numbers. There are inlet and outlet convection zones. Local studies of the structure are also analysed in relation to the whole sample and averaged in the form of global values. The test stand includes a measuring cassette, manometers, an air blower, meters of air stream mass (turbine and El-flow ones) and control valves. Homogeneous and multi-layer materials of thickness up to 50 mm can be tested. Measurements are carried out for samples arranged at different angles and with air streams of different magnitude, dividing the sample into layers Agi. It enables the evaluation of properties of textile products, their axial and circumferential irregularity as well as the determination of new physical modelling factors. The studies can also be used for comparative analysis of various textiles and evaluation of their suitability for different industrial applications.
Nowadays, pigment dyeing is one of the most interesting methods that is applied to make specific designs on denim and fashionable garments. Here, in this research, the bio-washing of pigment dyed denim has been considered with laccases. The desizing and bleaching of denim samples are first carried out and they are subsequently dyed with two types of pigments (Bemacol Blue GF and Ricoprint OSD Serie Blue) through the exhaustion method. The pigment dyed samples are then washed with various laccase concentrations, with and without the use of pumice stones. Color changes, bending and wrinkle recovery are examined. Furthermore, the surface morphology of the products is verified by a scanning electron microscope (SEM) and a Projectina microscope. The samples washed with laccases and pumice stones show higher dye stripping compared with those without the use of pumice stones. The bending properties of the samples treated by pumice stones show desirable results compared with the laccases, but this caused intense damage to the samples. Also, desirable results have been achieved by using laccases in the washing process. Treatment with laccases helps to obtain brilliant samples with decreased staining on the samples with a pocket and also lowers pigment discharge in the effluent.
Nomex fabric is irradiated by an Xe2 * excimer UV lamp (172 nm). The influence of different irradiating times and atmospheres (nitrogen and air) on the properties of Nomex fabric has been studied. The results show that the wettability of Nomex fabrics greatly improves when irradiated for 2 minutes. The scanning electron microscope (SEM) photos denote that the surface of the irradiated Nomex fiber is etched and the degree of etching in nitrogen is more severe than that in air. The XPS measurement proves that the surface of the Nomex fibers, which is irradiated in nitrogen and in air, generates carboxyl and hydroxyl groups. The results also show that the adhesive strength of the Nomex/polyethylene composite is reinforced by the irradiation.
This article uses a series of data mining techniques to analyze body types and introduce a new sizing chart in order to produce garments for males. A principle component analysis and hierarchical and non-hierarchical clustering approaches are used to form a new sizing chart. All variables are grouped into two main components with a principle component analysis. Agglomerative hierarchical clustering is used to determine the number of clusters, and then a k-means algorithm is applied to segment the heterogonous population to actually form the clusters. The resultant innovations in designing garments have improved both non-price and price factors, the fittings of garments on all bodies have effectively improved and fabric waste has decreased, so the main goals which include improvement in quality with more comfort and a lower price have been met.
This study discusses emerging design activities in the fashion industry and their implications for motivating sustainable consumption. The paper provides an insight into the broad opportunities of fashion activism for designers. As the basis for discussion and evaluation of the research questions, the author has compared the applicability of the bespoken strategies with selected findings from her own empirical case study. The case study entails two participatory clothing design workshops with 'half-way' products. The main research question elaborates on whether fashion activism can be considered as a tool for designers to help consumers defeat their desire to constantly consume more. This involves three sub-questions. First, how effective is fashion activism as a tool in raising awareness for sustainability issues in the fashion industry? Secondly, do participatory design processes and enabling solutions help the consumer gain new skills and develop a greater appreciation towards his/her products? This implies that the user can become his/her own designer and maker, and thereby possibly change his/her own behaviour and attitude through a deeper understanding of the production process. Therefore, and thirdly, can fashion activism ease the transition towards sustainable consumption? The final discussion will focus on the evidence gathered by the comparison of fashion activism strategies and the author's own research. The empirical case study has offered insight into the objectives of fashion activism specifically through half-way products. The findings positively confirm the expected advantages of half-way products. The half-way garments seem to ease the first step for user involvement. In addition, the research highlights the importance that consumers understand products and production. This understanding is a key factor for sustainable fashion consumption.
Most commercial textile materials are given a “soft finish” for the comfort of the wearer. This paper investigates the effects of two levels of concentration for six commercial softeners on cotton knitted fabrics. The fabric properties are measured by using the Kawabata Evaluation System for Fabrics (KES-FB). It is found that the application of softeners reduces the bending properties of interlock knitted fabrics due to the reduction in inter-yarn friction as the result of the lubrication effect of the softeners. For most softeners, a higher level of concentration leads to a softer fabric, but the optimum concentration level depends on the exact chemistry of the softener. Furthermore, the application of softeners does not reduce the shear properties of the knitted interlock fabric as expected. The main reason is that the shear deformation of a knitted structure is due to the stretching of the loops rather than inter-yarn movement as in the case for woven fabrics. The increased stability of the fabric after softener application makes the fabric more resistant to shear deformation. Therefore, for interlock knitted fabrics, shear properties are not reliable indicators of the softening effect.
Method and apparatus for a measuring of length and density of nap of fabric are presented. Method based on recording of laser radiation flux scattered by fibres that form nap. Experimental conditions provide unitary scattering of radiation by fibres and recorded light flux is proportional total length of fibres. It was found that total length of fibres in three samples of a heavy woolen cloth decreased exponentially as coordinate point recedes from cloth surface. The accuracy in the determination of the fibers total length in the nap is discussed. Modification of the method and the apparatus for a new goal is attained the hairiness of yarns measuring is described.

New disazo and polyazo ureido reactive dyes incorporating different reactive systems were synthesized and applied to cotton fabric by the exhaust dyeing method. Different factors affecting the dye ability and fastness properties of such dyes are investigated. Bis(monochlorotriazine) reactive dyes displayed higher primary exhaustion values compared to those obtained with bis(sulphatoethysulphone) and bis(monochlorotriazine/sulphatoethysulphone) reactive dyes under different neutral exhaustion conditions. The results obtained indicate that the fixation efficiencies of these dyes were higher than those of dyes incorporating the bis(dichlorotriazine) reactive system. The results assessed for alkaline exhaust dyeing indicate that the bis(monochlorotriazine/sulphatoethylsulphone) dye was less sensitive to the variation in fixation temperatures than the other reactive dyes. The fastness properties of the ureido reactive dyes were fair to good. The improved dyeing performance of such type of ureido reactive dyes should lead to the design of reactive dyes with good application and fastness properties on cotton fabric, and provide practical solutions for low-salt dyeing. The present study of synthesis of disazo and polyazo ureido reactive dyes of high molecular structure, and its application to cotton fabric by the exhaust dyeing method is novel and could be applied in the industry.
In today’s fashion world, technology has taken on an important role for the creation of novel design effects. As a type of digital technology, laser engraving is applied for decorative purposes with unique fashion design looks. With this technology, simple and complex patterns can be engraved onto the surface of garments by using laser beam scanning. This study explores the application of laser technology on assembled garments for diverse engraved patterns. To improve the visual appearance, different design methods, such as the graphic and resist methods, are applied for carbon dioxide (CO2) laser engraving onto garments made from rayon/polyester blended fabric with optimal laser engraving parameters, including resolution (dpi) and pixel time (μs). This study also reveals the many potential of fashion designs through the use of laser engraving technology. Based on computer-aided design, laser engraving could open up new possibilities for green fashion design with distinct patterns and textures that would cater to the demands of industries and consumers.
Hairiness is a very important yarn quality parameter for high speed weaving. This paper presents a comparative analysis of two modeling methodologies for the prediction of ring and rotor yarn hairiness. Cotton fibre properties measured by a high volume instrument (HVI) and yarn count have been used as inputs for artificial neural network (ANN) and linear regression models. The prediction accuracy for both of the models is found to be good as the correlation coefficient is higher than 0.92 and mean absolute error is less than 4%. However, ANN models have an edge over the regression model particularly for ring yarn hairiness prediction. The importance of the cotton fibre properties on yarn hairiness has also been analysed by the developed ANN and regression models. For ring spun yarns, the ranking of cotton fibre properties given by the ANN and regression models are generally in agreement although some disparities exist in the ranking of length properties. Both models yield almost identical ranking of cotton fibre properties for rotor yarn hairiness.
The Cutting Circle is an international research initiative by fashion designers/patternmakers and educators Timo Rissanen, Julian Roberts and Holly McQuillan. By exploring alternative methods of making clothes and patterns, we have employed 'risky' design practice, research and teaching to develop zero waste fashion and subtraction cutting. The project manifested as an intensive two-week practice-based research event, where via a series of collaborative collisions, experiments and design intersections, we asked the following three questions. What costs/benefits can we identify to aid the development of a sustainable fashion industry through risk taking at the intersection of our design practices? What new knowledge arises in risky collaborative design practice? And how can this new knowledge be best communicated to foster an environment of risk-taking within the traditionally risk adverse fashion industry? This paper primarily discusses our responses to the first two questions and related issues raised. It covers how experimenting with each other's design practice and practicing in each other's creative space as we both designed and made, enable the free transfer of ideas and cross-pollination, thus expanding our ability to identify links, gaps and opportunities. The Cutting Circle project has developed experimental practices with emphasis on the fusion of aesthetics, patternmaking, craft and socially invigorating design.
Owing to a high amount of stress, seam failure in workwear fabrics makes the fabric unsuitable although the fabric strength is high. It is therefore important to predict the seam strength to ascertain the performance of the garments during use and determine the required thread strength and stitch density to match the required seam strength. In all of the earlier predictive equations, seam strength is predicted from thread strength and stitch density along with some multiplicative factors. During the sewing process, a substantial loss in needle thread strength occurs; therefore, the thread becomes weaker than expected after incorporation into the seam. In this paper, the effects of various machine and process parameters are studied on thread strength loss and seam strength. The seam strength is predicted from the loop strength after considering the loss in thread strength. It is observed that higher seam strengths are observed when stronger threads are used for sewing. Loss in thread strength has a significant influence on the seam strength. Seam strength can be predicted using stitch density and thread loop strength, by considering the loss in thread strength during the sewing process. A closer match between predicted and experimental seam strength is possible.
A garment is regarded as desirable and beautiful if it covers the body with harmony and gracefulness. High drape, lightweight and soft handle fabrics are in demand, particularly for womenswear garments such as dresses, shirts, skirts, trousers and suits. Fabric drapability can be measured by a number of drapemeters for different modes of drapability such as static, dynamic and revolving. It has been shown that the drape coefficients, Ds , Dd and Dr , associated with these respective modes of drapability can be predicted from a combination of measurements from the KES-F system (Kawabata Evaluation System for Fabrics). In this paper we present the results of our studies on the prediction of drapability of lightweight wool fabrics, based on the KES-F system and drape coefficient predictive equations. It has been shown that the parameters Dr/Ds and Dd/Ds , called Indices of Drape Fluidity, Ir and Id , express the fluid drape behaviour better than Ds , Dr , D200 and Dd . This is because they discriminate and predict the drapability of fabrics better. Ir and Id have higher CV% than the Dr and Dd data, and therefore represent greater relative dispersion in a fabric group for drape. Various drape parameters of a group of wool fabrics have been compared with the four groups of polyester Shingosen fabrics, namely, New Silky, New Worsted, Rayon Touch and Peach Face, which are recognised for their soft fluid drape.
\nPurpose\nThis paper aims to prevent cotton textiles from fungi damage using eco-friendly aloe vera leaf extract, which was applied at a minimum amount, and cost-effective material.\n\n\nDesign/methodology/approach\nBatch extraction method using methanol solvent; phytochemical analysis was investigated and three-level factorial design of experiment and analysis of variance (ANOVA) was used for the optimization of 27 test runs. The finish was applied by pad-dry-cue at distinct concentrations, and the chemical property after treatment was studied. Colorfastness and coordinates are analyzed. Cotton fabrics were cultured with Fusarium oxysporum fungi and the anti-fungal property was examined and reported according to AATCC 30–2004 standard.\n\n\nFindings\nThe maximum yield of extract was at an optimum volume of 200 ml, 65 °C for 120 min. The effective antifungal fabric was achieved with minimum concentrations. There was significant strength loss in warp and weft direction. The treatment results in yellow-colored cotton fabric with fastness grade 3. The antifungal effect is durable until fifteen washes as the tensile strength losses were less than 1%.\n\n\nResearch limitations/implications\nThe findings of this work were based on samples considered in the laboratory. However, it can be reproducible at the factory production scale the treatment has the potential of yielding yellow dyed cotton fabric with multifunctional finishing.\n\n\nPractical implications\nThe treated fabric is against Fusarium oxysporum Fungi which is one of the vital antimicrobial properties of textile apparel products for various areas of application.\n\n\nSocial implications\nThe natural extract material applied to a textile material is eco-friendly effective against microbes of cotton seeds during cultivation and apparel end-uses.\n\n\nOriginality/value\nThe work application of fungi resistance on cotton fabric using aloe vera active component was original; this work provides extraction of the active agent from aloe vera leaf, which is optimized statically and successfully applied for anti-fungal activity on cotton fabric.\n

The efficiency of UV radiation on boiled aqueous and alkaline extracts of Eucalyptus bark powder has been determined. Irradiated and un-irradiated cotton fabrics were used to study the dyeing parameters such as material-liquor ratio, dyeing time and dyeing pH. Pre- and postmordanting were carried out by using copper and iron mordants. The data colour report was obtained for evaluation of un-irradiated and irradiated dyed cotton using a Spectra Flash (SF- 650) in the CIE Lab system. It was found that UV irradiation has the potential to improve dyeing and fastness properties, such as washing, light and rubbing, of cotton dyed with Eucalyptus bark powder.
Inter-fibre cohesion is regarded as an important property of assemblies, such as slivers, made of wool or any other fibres, with respect to the processing in carding, drawing (gilling) and spinning. In this paper, the results of the multiple regression analyses, and their validation, are presented to show that a strong relationship exists between the sliver cohesion (measured as sliver tenacity and sliver specific energy-to-break in a long-gauge tensile test) and a combination of the standard wool properties, such as bulk, mean fibre length (Barbe), mean fibre diameter and medullation content, used for the objective blend specification of New Zealand wools for marketing and processing.
A study has been carried out to investigate the past and present techniques, processes and procedures that enable creation of seamless fashion towards innovative ends. Among the fifteen techniques investigated, knitting and moulding are by far two of the most developed toward seamless clothing production. This paper gives a chronological review of the development of these two techniques pertinent to seamless garment production that could be deployed for seamless fashion creation.
Functionalized polyethylenimine–dye (FPEI) is prepared by mixing branched polyethyleneimine (PEI), in which its primary amine groups are modified at different ratios with a quaternary ammonium coupler (QI), and reactive dyestuff (RD) (QI/RD = 0/100, 20/80, 40/60, 60/40 and 80/20 mole/mole %). The deposition of FPEI from an aqueous solution onto the surface of cotton and wool fibres is studied. The adsorption of a charged polymer from an aqueous medium by cotton and wool fibres is investigated at different pH values, and the uptake of colour on fibres is measured by Datacolor and UVVIS spectrophotometers. The study of the kinetics of adsorption shows that pseudo-first-order kinetics provide the best correlation of the experimental data. The equilibrium data indicate that the deposition process onto both cotton and wool follows the Langmuir isotherm. In terms of colour strength (K/S value) the coated fibres compare well with those dyed with a commercial dyestuff, C.I. Basic Red 51, which suggests that the coating is a good alternative to classical dyeing.
Artocarpus heterophyllus Lam (local name jackfruit) belongs to the family of Moraceae. It produces natural dye from the bark of the tree which has been shown as a prospective natural dye source for textiles. In the present study, innovative extraction of yellow colorants using ultrasound energy is shown. Dyeing with jackfruit bark extract has been shown to give good dyeing results. Pretreatment with 1 % metal mordant and 4 % of bark extract (owf) was found to be suitable and showed very good fastness properties for cotton, wool and silk dyed fabrics with hue colors ranging from light brown to greenish to brown. The dye uptake by cotton fabric ranged from 55-62%, 68-70% for silk and 59-73% for wool with different mordants. The effectiveness of metal mordant-artocarpus in better dye uptake appears to be an improved process resulting in good dye adherence and good fastness properties.
Diabetes mellitus is one of the most common diseases around the world, and mainly affects the foot among the human body parts. The main causes of the diabetic foot are neuropathy, peripheral arterial disease and foot deformities; it leads to foot ulceration. Generally, sensory loss, high plantar pressure, foot deformities, inappropriate footwear, blindness, and age are the causing risk factors for developing foot ulceration in diabetic patients. Foot ulceration will result in prolonged hospitalization, high medical expenses, and serious complications with lower extremity amputation. For a long time, appropriate footwear has been recommended by physicians for reducing plantar pressure to prevent foot ulceration, the risk of amputation, and re-ulceration. A review is provided in this article towards the existing literature on the causes and prevalence of the diabetic foot, foot ulceration, off-loading pressure, footwear modification for different types of diabetic foot deformities, and types of footwear and textile materials used in footwear insoles for healing purposes.
In recent years, textile materials have been found in applications in the cosmetics field. A new sector of cosmetic textiles is introduced and several commercial cosmetic textile products are currently available in the market. On contact with human body and skin, cosmetic textiles are designed to transfer an active substance for cosmetic purposes. The principle is achieved by simply imparting the cosmetic and pharmaceutical ingredients into the fabric of clothing so that with the natural movement of the body, the skin is slowly freshened and revitalised. Microencapsulation technology is an effective technique used to control the release properties of active ingredients that prolong the functionality of cosmetic textiles. This paper will address the historical background of microencapsulation technology, its significant advantages and the most commonly used microencapsulation methods. Some typical examples of commercially available microencapsulation based cosmetic textile products will also be examined. Recent applications, as well as potential development in cosmetic textiles production, will be discussed.

“Clothes from heaven are without seam (Tian Yi Wu Feng)”, the Chinese idiom says. A study has been carried out to investigate the past and present techniques, processes and procedures that enable creation of seamless fashion towards innovative ends. This paper puts the study into context, summarises these techniques and processes as well as their procedures in creating seamless objects and/or clothing items. and further appraises the favourability of these techniques towards the ends of seamless fashion creation.
In this paper, XIANGRONG XI and ISAO AJIKI define an actual overfeed ratio depending on the recovered length of an overfed seam. In particular, the effect of the actual overfeed ratio on the bending properties of the overfed seam was measured and the effect of fabric recovery on the fabric overfeed ratio was investigated. The results show that, for all samples, the natural curvature of an overfed seam increases proportionally as the actual overfeed ratio increase, which is different from the situation with the overfeed ratio. The two definitions of actual overfeed ratio and overfeed ratio can be connected by factor η, which is affected by stitch length, and by the recovery and compressive properties of fabric. The results also show that the factor provided the same varying tendency as the fabric recovery ratio, and that the differences between the factor and the recovery ratio depended on the kind of fabric involved.
Tissue engineering has gained wide acceptance since its discovery due to its potential for replacing diseased and injured human tissues and organs. Biotextiles composed of textile fibrous structures can be designed and engineered to achieve specific performances demanded by various tissue engineering applications. Several key factors, such as the selection of cells, the material and form of the scaffold, and the regulation of cell growth and proliferation, govern the effective use of biotextiles for tissue engineering end uses. This paper examines the current techniques used in the field of tissue engineering and explains how the disciplines of polymer chemistry, fibre science, and textile technology and engineering have a unique role to play when combined with molecular biology, biochemistry, and biotechnology to design and develop novel biotextile scaffolds for tissue engineering applications.
In the present study, the “comfortability” of down-filled apparel has been evaluated in two different areas. The first aspect of the work deals with the evaluation of insulating capability of the down-proof fabrics and down-filled pillows in relation to relative humidity using the KES-F7 Thermal instrument and ASTMD1518 test method. Considerable differences in terms of true thermal transmittance have been obtained when fabrics and down-filled pillows are put under different relative humidity environment. With regard to the increasing requirements for comfort of the product, sensory feeling of the inner lining materials becomes a very important criterion for the selection down-filled garments. In this respect, the second aspect of the paper is concerned with the relationships between the fabric constructional, mechanical and transport properties and the psycho-physiological response of judges on the sensory feeling of lining materials. Significant relationships between the fabric transport properties, mainly wettability and transient heat conduction was obtained.
