This study examines the effect of the structural properties of F/W wool knit fabrics for woman's knitwear on the perceptions of textures and sensible images of consumers and present basic data for textile designing by analyzing the relationship among the structural properties, mechanical properties, objective hand measurements and preferences. A total of 12 kinds of knit fabrics were prepared and investigated in terms of the differences in the subjective, mechanical properties and objective hand measurements according to the structural properties of knit fabrics. The data were analyzed by t-test. The subjective hand attributes of wool knits through factor analysis are categorized into 6 factors. In particular, the 'active/comfort' factor is a meaningful result that reflects the unique characteristics of knit fabrics compared to woven fabrics. Mechanical properties and objective hand measurements have a greater effect on textures than on sensible images; in addition, the structural properties, 'gauge' was the most important factor to influence the subjective evaluation.

Through the recent pandemic, this study examined the theory of awe, which explains that external crises affect people's value systems and consequential behaviors. During the pandemic, some consumers expressed a growing interest in equity, while others pursued the consumption of materialistic items, such as luxurious fashion goods. According to the theory of awe, both of these phenomena could be coping responses to the crisis. Based on this, we attempted to understand the psychological processes behind the pandemic's effect on these two different consumers value systems thereby influencing sustainable consumption intentions: one through the new ecological paradigm (NEP) that emphasizes consumers' increased consciousness, and the other through materialism that emphasizes consumers' self-centered side. The results obtained from a survey of 382 U.S. consumers revealed that the degree of pandemic experience increased consumers' NEP and materialism, which also increased their economic and ethical CSR expectations. These CSR expectations then enhanced consumers' sustainable consumption intentions. As sustainable consumption and CSR are important agendas for the fashion industry, this study will provide useful insights for researchers and practitioners in the fashion field.

In this paper, water consumption annually for industries in Korea was estimated for the first time and based on this, an input-output model was prepared for water consumption analysis. Also making use of this, the direct and indirect water consumption effect according to industrial activities was analyzed and the total effect based on volume was broken down into each factor. The amount of water consumed for industries in Korea (excluding agriculture, forestry and fishery) was estimated about 7 billion and 692 million ton in 2003(excluding sea water). Classifying by industry, the one for electric power & water service accounted for almost half, 49.5%, metalworking industry for 24.3% and chemical industry for 5.0%. As the result of estimation for the direct and indirect water consumption inducement coefficients, the amount of water consumed per the production of one million won ranked the highest for electric power & water service as 113.8 ton and the next highest ones ranked as 49.6 ton for the first metalworking, 16.8 ton for textile and leather goods, and 11.9 ton for general machinery respectively. In the meantime, as the result of breaking down into each factor of total amount of water consumed by industry, it appeared that the ripple effect having on other industries was more than the direct effect.

Fur garment has long been the conventional symbol for luxury, or conspicuous consumption. However, as fashion items began to diversify as part of overall fashion trend, fur items are now more about individual taste and style than just lavishness. Synthetic fur is especially emerging as a new promising fashion material, with a touch almost like natural fur at an affordable price. Along with the emergence of 'Vegan Fashion' trend, synthetic fur is establishing itself as a popular fashion textile. This study is an attempt to investigate subjective evaluation and physical properties of natural and synthetic furs, whose results will further serve as basic data in developing synthetic fur materials. Sensory and emotional evaluations are carried out on natural and artificial furs. For analysis, factors such as weight, thickness, air permeability, gloss and compressibility were surveyed to observe how they influence the physical properties. According to the subjective evaluation, natural and artificial fur samples do not differ in conspicuous ways in appearance. Experiments on physical properties, specifically warm/cool touch experiment, show that natural fur has a slightly higher warm sensation than artificial fur. Luster analysis by using a microscope revealed that there are subtle qualitative differences between natural and artificial fur. During the subjective evaluation, subjects found it hard to state distinct quantitative differences in luster. A survey as a means of assessing qualitative differences in gloss seems to be necessary to complement the evaluation. Results from this study will potentially serve as resources for diversification of fashion product designs using synthetic fur.

The purpose of this study is for providing not only the latest design technique trend for zero waste fashion, but information about creative fashion design education through eco-fashion industry trend in globally and domestic which is focusing on eco-fashion labelling. The research were processed with literature related eco, sustainable, green fashion books, former articles, newspapers, and web sites. The results as follows; The certification about eco-fashion product is moving to 'Life Cycle Assessment' from focused on primary process like material, finishing, dyeing. Especially simplicity of process means reducing the wastes. And fabric wastage for adult outwear was estimated 15% percent of total fabric used in general design studios. Three cases for Zero waste fashion were as follows; First, Jigsaw puzzle by Timo Rissane and Mark Liu were different zero waste methods, but the result was same. Rissene's method was based on traditional cutting like 'cut and sew' but traditional cutting can lead to design that have an abundance of fabric and drape. Jigsaw of Rissene was approached with description a pattern-cutting technique in which all piece interlock with each other generating no waste from design production. Another Jigsaw by Liu was related with innovative textile design. DTP makes the possibilities for zero waste garment production almost endless. The dress intricately cut from 10 pieces, wastes none of the fabric required to make it. Second, Subtraction Cutting by Julian Roberts provides unexpected fluid, organic forms and zero waste fabric. Utilizing Roberts plug(tunnel) technique enables any part of the garment that is removed for fit or aesthetics to be reincorporated into the design of garment. Third was 'Bio Couture' by Suzanne Lee. She has created garments from cellulose bacteria which grow in a bathtub using only green methods addressing in such as way ecological issues and exploring the future of fashion design in conjunction with technology.

The pigment extraction of Opuntia ficus-indica has been conducted to develop useful natural dyes in place of synthetic dyes which are suspected to bring serious environmental pollutions. The dyeing ability on wool fabric by addition of ascorbic acid and several mordants were investigated by means of color measurement. In addition, the fastness of washing, perspiration, rubbing, light, dry cleaning, effect on bacterial reduction and UV-B protection were also investigated. From these investigation, it is suggested that the pigment extracted from Opuntia ficus-indica can be used as a source of natural dyes and the obtained result are as follows. 1. Maximum absorption band (${\lambda}max$) of Opuntia ficus-indica extract is 533nm. 2. The wool fabric dyed with Opuntia ficus-indica extract has stable color by the addition of ascorbic acid and is achieved with addition of 0.1% ascorbic acid, 0.5% several mordant, and three repeated dying at $50^{\circ}C$ for 1.5hr. 3. The wash fastness of the dyed wool fabric when it is washed with neutral detergent is more effective than alkaline detergent. The dry cleaning fastness of the dyed wool fabric is more excellent. In addition, the perspiration fastness of the dyed wool fabric is increased by mordanting method. And than the rubbing fastness of the dyed wool fabric is showed excellent under dryness and wetness. Light fastness of the dyed wool fabric, however is showed inferiority. 4. The wool fabric dyed with Opuntia ficus-indica extract is showed effective bacterial reduction and UV-B protection is increased remarkably.

This study explores the effects of X-ray irradiation for biological control and high-temperature degradation on dye stability in dyed textiles with Gardenia. To evaluate this study, optimal extraction solvents for these textiles were identified by comparing them with a crocin standard solution. Extraction using pyridine closely matched crocin. The study then assessed the stability of X-ray irradiation and high-temperature degradation on these textiles. Transparent yellow dyes were observed in all samples. Color differences were found to increase at higher irradiation doses and longer degradation periods. While UV spectroscopy spectra showed broadening and lowering trends with higher irradiation doses and longer degradation periods, suggesting a reduction in colorant transition, mass spectrometry revealed minimal chemical changes. In conclusion, both X-ray irradiation and high-temperature degradation induced spectral changes without complete dye decomposition. Major colorants were consistently detected.

Polytetrafluoroethylene (PTFE) fibers are widely used in the textile industry, filter media, membrane distillation, electronic appliances, and construction. In this study, PTFE-polyethylene oxide (PEO) fibrous membranes were fabricated by emulsion electrospinning; subsequently, pure PTFE nanofibers were obtained via sintering. PTFE-PEO electrospinning solutions were prepared using different weight ratios to determine the optimized condition. As the ratio of the PEO increased, the fiber structure improved. Scanning electron microscopy and Fourier-transform infrared spectroscopy observations indicate that PEO is removed and PTFE fused gradually to form bonds among them during sintering. The obtained pristine PTFE membrane demonstrated hydrophobicity at 143.6° water contact angle and oleophilicity at 0° oil contact angle, which is known to be utilized for oil/water separation. A simple separation experiment was performed to remove oil droplets from water. The PTFE membrane exhibited good chemical stability and a high surface-area-to-volume nanofiber ratio. These excellent properties suggest that it is applicable to oil/water separation in harsh chemical environments.

This study is on the fashion design of velve, concentrating on the kinds and the images of it. The velvet, the pile fabrics, includes velveteen, velour(s), corduroy and plush. Ancient Chinese invented it first but Westerners used it widely in fashion since 14C because of the deep colors and the glimmering lights. In 20C the developments of textile industry, the mass production and the dyeing techniques made it popularized as velvet fashion. The velvet must be handled carefully and stretch velvet in vogue today needs the different pattern design and the dressmaking from general fabrics. 'For example, 55 size (bust girth 33", waist girth 26", hip girth 36") Jacket for ladies of stretch velvet, 3/4"ease in the bust line is eliminated at the back on the block pattern after normal pattern design. The costume of velvet has the images of elegance, nostalgia, and oriental ism. It has established the high quality, rich and refined elegance of Haute Couture. It could express the image of nostalgia, the longing for the past with the remarkable splendor. The orientalism of velvet costumes has represented the westerner's aspiration and imagination about the Orient with the intense color and over-decoration.
