Facial cosmetics moisturise the skin and remove sebum and impurities to maintain healthy skin. Face masks are available on the market in various forms such as gel, emulsion, sheet and paste. The textile sheet mask for facial care is used by all women, regardless of age. This study deals with 3D scanning of women’s faces to create an average female 3D face model for the development of a textile sheet mask design for facial care. Screened Poisson surface reconstruction was used to create an average female 3D face model whose dimensions correspond to average dimensions of scanned female faces. A reliable average 3D face model of the women studied was therefore used to develop a textile sheet mask for facial care. A comparison of average facial measurements with the measurements of randomly selected masks on the market revealed differences. Therefore, a design for a textile sheet mask was developed based on average facial measurements and the average 3D face model of a woman and by using virtual prototyping. The use of software for prototyping and simulating the appearance of clothing has also proven to be effective in the development of a textile product such as a textile face mask. The developed pattern design of the textile sheet mask with optimal dimensions and shape adapts to the contours of an average woman’s face. This fulfils all the requirements for wearing comfort of the textile sheet mask around the eyes, nose and lips during facial care and enables efficient transfer of the serum from the textile sheet mask to the skin.

Comprehending the degradation of glass fibers is crucial for service applications involving dry and wet conditions, especially when prolonged contact with water above room temperature is present. Depending on the polymer material, both thermosetting and thermoplastic matrices can permit the ingress of moisture. Therefore, fiber reinforcements embedded in the polymer matrix may experience moisture exposure. Additionally, some structural applications use fiber devoid of any matrix (dry fibers), in which water exposure must be avoided. In all of these cases, moisture may, therefore, have a significant impact on the reinforcing elements and the rate of degradation. The present work focuses on the effects of hydrothermal aging on the mechanical durability of long E-glass fibers by immersion in water at 60 °C, 71 °C, and 82 °C. A service life forecast model was created utilizing the Arrhenius technique, and a master curve of strength variation with exposure time was created for E-glass fibers at 60 °C. Using this modeling approach, it is possible to approximate the amount of time it will take to attain a given degradation level over a specified range of temperatures. Scanning electron microscopy was used to evaluate morphological changes in fiber surfaces due to hydrothermal exposure, while Fourier transform infrared spectroscopy and mass dissolution studies were used to elucidate the mechanism of the strength loss.

Abstract The purpose of this study is to raise awareness of the uniqueness and excellence of Korea’s traditional culture among members of the MZ generation (Millennials and generation Z) and explore the possibility of utilizing archetypes of traditional culture in the contemporary context. To that end, this study develops and proposes unique contemporary textile pattern designs applying M. C. Escher’s tessellation technique to the formative characteristics and symbolic meaning of Chaekgeori icons. To develop the designs, this study reviews the previous literature and theoretically considers the concept of Chaekgeori, its formative characteristics, and Escher’s tessellation. After extracting iconsrelated to the themes, stylized iconographic motives were applied to geometric shapes to create repeating units. Then, Escher’s tessellation was applied to these repeats to develop twelve contemporarily reimagined textile patterns. To verify the usability of the developed textile pattern designs in products targeting the MZ generation, in-depth interviews were conducted with the MZ generation living in Jeju. The developed textile patterns were mapped onto the selected items to prove the applicability of the developed textile patterns to the items preferred by the MZ generation. The contribution of this study lies in the fact that it develops unique and contemporary textile pattern designs based on the formative characteristics and symbolic meaning of Chaekgeori icons and maps the designs of fashion items preferred by the MZ generation, thereby raising awareness of the value and excellence of Chaekgeori as a part of Korea’s traditional culture and shedding light on the possibility of using traditional cultural archetypes in contemporary contexts.

Drilling is an inevitable process for component assembly which need appropriate control aiming damage reduction. To study such drill-induced damages, Glass and Natural fiber composites with unidirectional (11) and cross-ply lay-up (12) were drilled using Twist and Annular Core drill tool of varying diameters (6 and 8 mm). The derivative of modal analysis (natural frequency, damping) and delamination are the factors considered for the analysis. In the chosen laminates, maximum variation in the natural frequency was observed to be 8.98% in N12 and 8.60% in G12 for twist drill of 8 mm, whereas the core drill of 8 mm contributes to 0.51% and 0.54%. A similar trend was observed in damping factor showing a maximum variation of 26.98% (N12) and 11.30% (N12) with 8 mm twist and core drill, respectively. Similarly, the maximum delamination factor was observed to be 1 .62 and 1.30 with 8 mm core drill in G12 and N12 which is lower than the 6 and 8 mm twist drills. Further, twist drilling experiences both peel-up and push down delamination in N12, N11 which was eliminated by the core drill. Thus, core drill exhibits distinct advantages with reduced damage and retained structural properties.

This work is concerned with the characterization of pulp extracted from agro-waste fibers using steam explosion technique. Steam explosion is a very efficient and non-reactive technique to extract soft and absorbent cellulose pulp from agro waste fibers like banana, bagasse, and sisal. Preforms prepared from the extracted pulp, with the aid of binders, using the water laid method, enhanced their suitability to be used for sanitary napkins, due to improved fiber integrity and absorbency. The preforms developed from these extracted pulp were used as the absorbent core of the sanitary napkins to replace the widely used synthetic viscose wood pulp, which thereby improved the eco-friendliness of the sanitary napkins. The preforms were made from these pulps in combination with various binders namely cassava, carboxymethyl cellulose (CMC), and sodium alginate in various concentrations namely 0.1, 0.2, 0.3, 0.4, and 0.5%. The various preform samples were tested for physical and absorbency-related performance characteristics like grams per square meter, thickness, density of the pulp, absorbency and immersion time, vertical wicking, strike through rate and swelling measurements. It was found that the preforms made with cassava as the binder, recorded higher absorbency properties when compared to other preforms, which were made using CMC and sodium alginate.

The success of students and their performance are influenced by manifold parameters. The current study focusses especially on the correlation between study duration and the student performance. Investigated are the numbers of two textile related courses (bachelor and master) over the complete time frame of one decade. Data of more than 800 students are considered. Data evaluation is done with the final marks of the students and by using a calculated value – the student performance index PI. Especially discussed is the behavior of long-time students needing more than the double of the regular study duration. In this study only results of students are discussed which successfully finished the study course with a degree. Students leaving without a degree are not considered. For the bachelor course a correlation of their final grades with larger study duration can be determined. In contrast, for the master course nearly no influence of the study duration on the student performance is determined. A possible explanation for these different results can be discussed with the different reasons for longer study duration. For master course it is obviously the situation that the studying is combined with part-time or even full-time jobs. This combination of job and study course leads even for excellent students to prolonged study duration. With this background, for future developments a special designed part time master study course should be developed and offered for students who like the combination of a job carrier with gaining simultaneously a master degree.

In recent years, the use of color-adsorbing nonwoven as a dye transfer inhibitor to prevent the cross-staining of fabrics in home laundering has received great attention. In this work, a color-adsorbing nonwoven was used to adsorb the dyes desorbed from dyed silk textiles and thereby provide an anti-staining effect in the washing. The nonwoven consisted of cationic regenerated cellulose and polyolefin fibers and had an isoelectric point of 7.82. The adsorption properties of acid dyes on the nonwoven and the anti-staining of the nonwoven were studied. The adsorption kinetics and isotherms of acid dyes on the nonwoven followed the pseudo-second-order kinetic and Langmuir adsorption models, respectively. With increasing temperature, the adsorption saturation increased, and the Langmuir affinity constant decreased, indicating an exothermic effect. The adsorption of dyes with high molecular weight showed great temperature dependence. During the washing of dyed silk textiles, the strong adsorption capability of cationic cellulose for desorbed acid dyes contributed to the anti-staining effect of color-adsorbing nonwoven.

This study presents animal fiber characterization and the influence of various fiber loadings on mechanical properties of sheep hair fiber-reinforced polymer (SHFRP) composites. The sheep hair fibers (SHF) characterization was carried out using X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FTIR), thermo-gravimetric analysis (TGA), scanning electron microscopy (SEM) and non-contact surface roughness machine. The functional group and chemical bond were analyzed using FTIR techniques. The crystallinity index and thermal stability of the SHF were characterized, using XRD and TGA techniques, respectively. The composites were fabricated using a compression molding technique and a varying weight percentage of 20, 30 and 40 fiber. The composite plates were cut into test samples according to ASTM standard methods for their mechanical (tensile, flexural and impact) behaviors to be extensively analyzed. The surface morphology of the fractured samples was examined with aid of an SEM. From the results obtained, it was evident that the SHFRP composite recorded a significantly increased tensile strength property when fiber loading was increased from 20 to 40 wt%. The optimum 40 wt% SHFRP composite sample recorded better flexural and impact strength, when compared with other counterparts. This was attributed to a better fiber-matrix interfacial adhesion, as established fromSEM micrographs.

Bleaching of jute has become essential for making white glossy fabric or base material for coloration intended for value added and diversified products. The conventional hot hydrogen peroxide bleaching process produces white fiber with high loss of tensile strength and impairing the feel. On the other hand newly developed peracetic acid bleaching of jute produces minimum loss of tenacity without impairing the feel but whiteness achieved is slightly low. Partial bleaching of jute was carried out using 25%, 50%, and 75% of the normal dose of bleaching agents and their whiteness index as well as tensile strength were evaluated. In all the cases hydrogen peroxide produced 5–8 grade higher whiteness in HUNTER scale while peracetic acid bleached sample retains higher tensile strength. So, two-step bleaching was carried out using hydrogen peroxide and peracetic acid following single-bath and double-bath processes. Two-step single-bath bleaching of jute fabric using 75% peracetic acid followed by 25% hydrogen peroxide bleaching treatment results in best effect with respect to optical and physical properties.

The sportswear industry has a growing market globally. In the sportswear retail market, where the primary focus is on providing customers the product, but provision of the necessary ancillary service also takes place, the service quality and its relation to customer satisfaction and customer loyalty are important. With an attempt to find out this relationship, the data for this study was obtained from 251 people living in Turkey. The service quality was described as a second-order construct with the dimensions proposed in SERVQUAL scale. Confirmatory factor analysis and structural equation modeling were used to analyze and validate the model. The findings showed that the service quality, together with the relevant dimensions, tangibles, reliability, and assurance, has an influence on the customer satisfaction but not on the customer loyalty. Nonetheless, it was confirmed the customer satisfaction has an impact on the customer loyalty.

This study was focused on the growth of multi-walled carbon nanotubes (MWCNTs) on iron chloride-functionalized silica microspheres. In addition, the microwave absorption potential and the subsequent heat production of the resulting structures were monitored by means of infrared thermometry and compared with pristine commercially available MWCNTs. The functionalized silica microparticle substrates produced MWCNTs without any amorphous carbon but with increased structural defects, whereas their heat production performance as microwave absorbents was comparable to that of the pristine MWCNTs. Two-minute microwave irradiation of the SiO<sub>2</sub>@CNTs structures resulted in an increase in the material’s temperature from ambient temperature up to 173 °C. This research puts forward a new idea of charge modulation of MWCNTs and sheds light on an investigation for the development of bifunctional materials with improved properties with respect to efficient microwave absorbance.

The emphasis is on the textile potentials of the city of Leskovac, the textile museum. The author examines the geographical, economic and cultural position of the town of Leskovac as an industrial and fair city. It also advocates the preservation of old factories as important tourist destinations. It also shows the development of other industrial branches according to which this city is known, as the chemical, pharmaceutical, food and metal industries. The aim of the paper is to point out the significant possibility of tourism development through the adjustment of old industrial plants into craft and industry museums, as there are not many in these regions.
Abstract This study explores the roles of vividness and interactivity—two technological dimensions of virtual reality mediums—for consumers’ approach intention toward immersive virtual reality stores. In addition to telepresence, a well-established variable in explaining the effectiveness of virtual mediums, this study proposes experiential value as the second mediator that can lead to successful consumer experiences in commercial virtual environments. We recruited 101 volunteers who were willing to experience a virtual reality store with head-mounted displays. The results show that participants who perceive higher vividness and interactivity of an immersive virtual reality store tend to show stronger approach intentions, and that such positive influences are serially mediated by perceived telepresence and experiential shopping value. In multiple-step mediation analysis, the perceived experiential shopping value is found to be the key determinant in evoking consumers’ approach intention. The study concludes that virtual reality stores should be built in a way that provides experiential value by utilizing strong telepresence to achieve positive consumers’ approach intention. Suggestions for further research and practical applications are also discussed.

Abstract This study aimed to determine the differences in the EMG of thigh among film-welded compression suits (WCS), film-free compression suit (CS) and a loose sportswear during knee joint exercise. To differentiate the effect of clothing variable accurately, two types of compression suits were made elaborately using the same material and 3D pattern. Difference in two compression suits is only whether film was welded or not. EMG was observed during isokinetic exercise of flexion and extension, comprising four sets of maximum contraction of thigh at the angular velocity of 60, 180 and 240°/s using Cybex 660. When the WCS was worn, the mean muscle activities of the anterior thigh was generally higher during extension, especially in the left rectus femoris (RF) and right vastus oblique medialis (VMO) throughout the exercise. Wearing WCS enhanced mean muscle activities and decreased muscle fatigue of VL and VMO at each angular velocity, however, it did not support the mean muscle activity nor the fatigue of the hamstrings in almost all conditions of exercise. Muscle-specific EMG implies that film-welded compression suit designed in this study is beneficial to VMO, inducing high muscle activity with less fatigue during knee extension.

Abstract Physical attractiveness affects people’s lives in numerous ways. This study examined the effect of a woman’s body attractiveness on favorability perception based on the ‘beauty-is-good’ stereotype in the context of South Korea. Body attractiveness was operationalized using tallness in Study 1 and slimness in Study 2. The two studies tested the effect of a woman’s body attractiveness with the consideration of participants’ gender and the dependence of participants’ self-worth on their appearance. A general linear model with a 2 (target woman’s bodily attractiveness: high vs. low) × 2 (participants’ gender: female vs. male) design and participants’ appearance-contingent self-worth as a continuous predictor was performed. Results of these studies indicated that participants’ gender and appearance-contingent self-worth moderated the positive effect of body attractiveness on favorability perception; specifically, this effect was supported by men with high appearance-contingent self-worth and women with low appearance-contingent self-worth. Interestingly, women with high appearance-contingent self-worth showed opposite effect of body attractiveness on favorability perception in Study 2. These findings extend the effect of the beauty-is-good stereotype to bodily aspects and address the interaction between participants’ gender and appearance-contingent self-worth. Discussions on tallness and slimness are provided.

Silk and cotton fabrics were dyed using the extract from blackcurrants, and the properties of the dyed fabrics were investigated. The natural dyes present in the blackcurrants were identified as four types of anthocyanins, i.e. delphinidin-3-glucoside, delphinidin-3-rutinoside, cyanidin-3-glucoside, and cyanidin-3-rutinoside. The colors of the fabrics dyed with and without five types of mordants, including Mg2+, Ca2+, Al3+, Fe3+, and Cu2+, were measured and expressed according to the CIELAB color system, Δ E* value, and K/ S value. The affinity of the extracted dye for the silk fabric was higher compared with that for the cotton fabric. The crystallinity of silk was lower than that of cotton. The fabrics dyed with blackcurrants had UV shielding ability, especially at 330–400 nm, and antibacterial properties. Although color fastness to light and washing (color change) was not sufficient, treatment with Mg2+, Fe3+, and Cu2+ mordants could enhance the color fastness.
