We developed a demonstration software program for quick response system of apparel industry in order to educate students to get used to its expert system and computerized environment of this field. Merchandizing-Sourcing-Production-Retail shop chain of the processes in apparel company are the main pages in web to show students majoring clothing and textiles through the multimedia classroom. Up and down stream in the long process of apparel industry needs to shorten the process time that includes communication and instruct form letters between apparel company, textile company, sewing company and shops. Apparel company has pages and functions of online confirmation among designers and MDs, sample making order sheet, cost accounting sheet, and other worksheets. Textile company has textile list, confirmation of textiles and estimation sheet. Sewing company has sewing order sheet, production cost, manufacture process status and delivery order status. Four stage companies are connected to each other and can share, receive or send the data generated in each manufacturing process. This system can improve the understanding of students through displaying the whole process of apparel industry and testing each related tasks with many work sheets.

Compressional Properties of Fabrics at Low Pressure to Assess Real Fabric Handle

나영주,Na, Young-Joo 한국의류산업학회 1999 한국의류산업학회지 Vol.1 No.4

Twenty-three fabrics of varying thicknesses and weights were subjected to the maximum pressures of 10, 20, 35, 50 and 70 $gf/cm^2$ to yield pressure-thickness curves. Compression property values were plotted according to the amount of pressure applied to the samples. Pressure increases resulted in decreases in LC (compressional curve linearity), increases in WC (compressional energy) and no change in RC (compressional resilience). The best-fit lines are found separately according to pressures. The thickest fabrics exhibited the highest LC and WC values. The slopes varied different according to the pressure applied, with a pressure 50 $gf/cm^2$ exhibiting the steepest slope at We. The pressure of 20 $gf/cm^2$ correlated most closely with the hand-evaluation test results, yielding Spearmans correlation coefficients of .86 and .82 respectively for the LC and WC. 두께와 무게가 다양한 23종의 직물을 대상으로 최대하중 10, 20, 35, 50, 70 $gf/cm^2$의 5종류 다양한 조건 하에서 압축-두께곡선을 측정함으로써 저응력에서 압축특성과 두께, 태를 분석하였다. 최대하중이 증가함에 따라 LC(curve linearity)는 증가하였으며 WC(compressional energy)는 감소하였다. 또한, 최대하중에 따라 RC(compressional resilience)는 변화가 없었다. LC와 WC는 직물이 두꺼울수록 크게 나타났으며 RC는 중간 두께의 직물에서 가장 크게 나타났다. 최대하중 20 $gf/cm^2$에서 측정한 LC와 WC가 주관적 태 평가결과와 가장 상관이 깊었으며 Speamnan's rho는 .86과 .82였다.

The efficiency and benefits of product information of products consisting of natural substances, such as bamboo, charcoal, green tea were explored. The underwear evaluation before/after getting product information was considered through questionnaire survey method. They were asked to guess the price and the natural substances before and after knowing the product information. The subjective responses of comfort and tactile sensation while subjects were exercising in a hot, dry environment were measured experimentally. Their preference and tactile sensations were different after the product information was told. In early running period, the subjects felt comfort mostly in the charcoal underwear, since it absorbed perspiration. In late recovery period, they felt comfort mostly in the bamboo underwear for its quick drying. New underwear products were assumed as higher price than controlled underwear, and after acquiring the product information they guessed much higher prices to the same product, answering the changes in the subjective sensation, too.

The purpose of this study was to investigate college student's behavior when searching for textile information or identification. We also looked into their expectations for apparel material according to textile knowledge. 260 questionnaire were collected and analysed using factor analysis, reliability analysis, and a t-Test using SPSS. The questionnaire for search behavior when looking for textile information was divided into 4 sections: subjective, objective, sustaining, and before-purchasing search. 5 Textile expectations were defined as tactile comfort, pilling or wrinkle free, ease of washing or maintenance, and ease of body movement. The results showed college students have relatively high textile knowledge than the awareness of the importance of textiles. They usually use sustaining search for textile identification and have the highest expectations in terms of a fabric pilling or being wrinkle free. The greater their awareness of textile importance they have, the higher the textile knowledge they have. It showed that the search behavior for textile information differed according to material knowledge, and the participants in the high knowledge group used their accumulated subjective and experienced textile information. The student's material expectations are related to their cognition for textile importance rather than their textile knowledge. When looking at search behavior for textile information, textile identification is found to be related their expectations for textile material positively.

이미지 분석을 이용한 아라미드와 시뮬레이션 부직포의 기공 형태 측정

This is a report of characterization and simulation of pores in nonwoven fabrics and application of techniques developed for analyzing structural information by imaging. Aramid nonwoven fabrics and simulation of nonwoven fabrics were investigated in terms of pore round-ness, pore ellipticity and pore orientation. Changes in pore properties resulting from web density or variation in fiber orientation were characterized by geometrical technique for seven simulations and two aramid nonwoven fabrics. As the density of nonwoven fabric increased, pore roundness, ellipticity, and orientation did not change substantially, but as the fiber orientation of nonwoven fabric was randomized, the pore shape parameters changed significantly.

The purposes of this study are to investigate the tactile sensibility and preference of cotton jersey before/after the treatment of softener washing finishing and to look for the relationship of tactile sensation and consumer preference, in order to provide the basic data for the development of new cotton products. We surveyed the tactile sensation and preferences of cotton jersey to 40 college students when asking them to handle $30{\times}30cm^2$ of fabric treated with/without finishing: Enzyme, Ultra soft, Silicone, and SBS washing finishing. All softener washing-finished fabrics were felt softer, flatter, more flexible, limper, moister, thinner, and more stretchable than before treatment, and consequently better feeling and higher preference. In case of thermal sensation, they felt that fabric with Enzyme finishing was cooler than before treatment, while other fabrics were warmer. And they felt Silicone and SBS finishing fabric were even lighter than before, while Enzyme and Ultra soft finishing were even heavier. Most preferred was SBS washing, but Silicone finishing fabric received the highest tactile comfort, this is for they received higher feelings in the sensations of smooth, soft, stretchy, thin, light and wet. We displayed the tactile sensation words and finishing types together on 2D scale of 'softness' X axes and 'heaviness' Y axes.

This study tests the performance of the recommended winter dress OnMapsi for an office worker through the analysis of skin temperature changes according to the heating environment. We tested and compared the effects of with/without undergarments for 4 male subjects in an artificial-climate chamber with two air temperatures of 19℃ and 22℃, 50±10% R.H. During the 60 minute experiment that simulated office work, the subjective feelings (that included thermal, humidity and comfort sensation, and skin temperature) were measured at equal intervals. The results show that the forehead and chest skin temperatures were not affected by air temperature or clothing type, while the hand and foot skin temperatures were affected at 0.3-0.9℃ depending on clothing type and 1.9-2.2℃ depending on air temperature. The mean skin temperature was decreased by the experimental time pass more with regular formal wear than with OnMapsi. The second experiment located the ambient temperature in which subjects wearing OnMapsi show equal skin temperaturesto those without undergarments at 22℃. Therefore it is possible to decrease heating temperatures to 18-21℃ in the office for winter OnMapsi wear that produces a skin temperature and thermal sensation that is the same as those at 22℃.

The Korean wintertime Onmapsi Campaign recommends wearing underwear, layered clothing, or thermal accessories in an indoor environment of a lower than room-heating condition. We surveyed 132 government officers, about Onmapsi wearing conditions and campaign satisfaction. The term was found to be unfamiliar to them, even if they wore underwear or thermal accessories as participants in the campaign for the wintertime office of low temperature 18-20℃. They wore thick shirt/pants or cardigans/sweaters; however, underwear or thermal vests was worn relatively less. They wear 2.9 layers on top and 1.7 layers in bottom in average. They have their own methods to keep the body warm, which are using 1) functional thermal clothing, such as turtleneck shirts of heat technology new material, 2) functional thermal accessories, such as warmer and muffler, 3) functional office goods, such as a thermal computer mouse and blanket on the desk. The campaign requires more advertisement, a revision on the details of the proper wintertime indoor environment, and develops the varieties of Onmapsi apparel.
