The condition of covering process using thermoplastic polyetherester elastomeric fibers(TPEE) was established. Two types of core yarn(TPEE, Spandex) and one type of effect yarn(PET) were used as materials to confirm the change in physical properties of covering yarn under various covering conditions. In addition, the effects of the treatment temperature on the elongation at break of covering yarn after heat treatment was analyzed. Through this analysis, it was confirmed that the elastic recovery of TPEE which is used as the core yarn was increased with the draw ratio, but decreases when it exceeds 1:2.5. And the elongation at break of the covering yarn could be increased by increasing the twist per meter of it. Additionally, it was confirmed that the elastic recovery of TPEE which is used as a core yarn, could be increased by applying heat treatment.

This study determines the differences between Korean female university students and their Chinese counterparts residing in Korea by evaluating the subjective sensation and tactile preference in fabrics for casual shirts. Seven types of white causal shirt fabrics were selected as specimens from those available in spring and autumn shirt collection. The fabrics were made from various fibers (cotton 100%, polyester 100%, flax 100%, polyester 80%/cotton 20%, polyester 65%/cotton 35%, polyester 50%/cotton 45%/spandex 5%, and polyester 50%/modal 50%). Forty Korean and Chinese female university students subjectively assessed the subjective sensation of fabrics used for casual shirts. Participants were asked to observe the seven types of fabrics and complete the questionnaire. The subjective sensation to be assessed for white casual shirt fabrics was classified into the following four factors: smoothness, lightness, softness, and stretchiness. Subjective sensation factors showed partially significant differences by nationality. Korean female students evaluated cotton fabric as being light, whereas their Chinese counterparts evaluated the polyester/cotton/spandex blended fabric as light. Korean female students evaluated polyester/modal blended fabric as being stretchable. The tactile preference for fiber composition of the fabrics showed partially significant differences by nationality. Korean female students preferred cotton 80%/polyester 20% blended fabric, polyester 50%/cotton 45%/spandex 5% blended fabric, and flax 100% fabric. The subjective sensation of the fabrics had different effects on preferences by nationality. Smoothness and softness had positive effects on preferences for the fabrics of Korean students. However, smoothness, softness, and stretchiness had positive effects on the preferences of Chinese students. The subjective sensation and tactile preference for casual shirt fabrics showed a difference between Korean female students and their Chinese counterparts. Therefore, when planning casual shirt fabrics for female university students, it is necessary to reflect on these differences in subjective sensation and tactile preference.

This study provides basic data for the development of jacket patterns which reflect designs corresponding to the body shape features and preferences of obese women in their 20s and 30s by understanding problems they may encounter in wearing a ready-made jacket by researching the reality of ready-made tailored jacket wearing and their design preferences. A survey was conducted by sampling 82 obese women (over $25kg/m^2$ BMI) between the ages of 20 to 39. The details of the survey consists of general information, interest rate and importance rate on clothes, reality of wearing and purchasing jackets, measurement fits per each part, and preferred designs. SPSS 14.0 was used to analyze the data. The results showed that 76.8% of obese women wore their jackets less than 5 times a month. Those in the 20s wore the jackets more frequently than those in the 30s. The reasons for not wearing jackets frequently included uncomfortableness in activities and unavailability of the correct size. A total of 55% of the total preferred the fitting to be relatively smaller than the body size or tightly fitting. Although in the past, there was a tendency to wear a loose fit to cover the body shape, currently even obese body shapes avoided the loose fit as the tight fit is the trend. In terms of the satisfaction rate for the measurements per each part of jackets, there was a low satisfaction rate for most of the items. For the circumference items such as waist length and chest size, people responded that they were too small and for the length of items such as the length of jacket and sleeve length, people responded that they were too long. This was because the readymade clothes brands increase the length of items and circumference items in uniform in the same intervals when producing large sizes. Both those in the 20s and the 30s preferred a tight fit. In terms of preferred fabric, a wool/spandex mix was most popular and then cotton/spandex. This shows that they prefer those fabrics which allow an excellent activity while maintaining the exterior well. In addition, they preferred black color with no patterns because they wanted their body size to look reduced and did not want to receive any attention.

This study attempts to propose a pattern design of snug fitting midi briefs for women. Each briefs made of two kinds of fabric, cotton 40's and cotton 40's spandex, was produced for the research in a different shrinkage rate. The result of wearing test of the briefs-sold-in-the-market (BSM) and the briefs-specially-made-for-this-research (BSMR) were as follows: BSMR showed a higher mark than that of BSM in the sense of close fit on the torso, comfortableness, sense of being tight, satisfaction and beauty. In particular, the back design line of BSM gave a lower satisfaction to test wearers, while that of BSMR gave a more comfortableness to them, making their hip comfortably being wrapped by making smoother the angle of the straight line linking sidelines with clutch part, and making sidelines into curve. In a forward research, further studies about grading and other patterns but midi pattern of briefs would be examined.

This study provides product survey data for the development of medical compression stockings. An investigation analyzed imported medical compression stockings of 40 brands from 6 countries sold in the Korean market, such as Jobst$^{(R)}$, Therafirm$^{(R)}$, Rxtar$^{(R)}$, Varicoin$^{(R)}$, and Sheer&Soft (USA), Sigvaris Venosan$^{(R)}$ 4000 (Switzerland), Best$^{(R)}$ and Segreta$^{(R)}$ (Italy), Venex$^{(R)}$, Star cotton, Doktus$^{(R)}$, Maxis$^{(R)}$, Maxis$^{(R)}$ Cotton, Lastofa$^{(R)}$, and Memory Aloe Vera (Germany), and Gunze (Japan), Venos and Yolanda (Taiwan). The main fibers of compression stockings were nylon and spandex; in addition, the fiber content was different by country and brand. The number of compression classes of imported products was USA (5), Italy (5), Germany (4), Switzerland (3), Japan (3), and Taiwan (3). For basic body measurements, USA and Swiss brands used ankle circumference, calf circumference, thigh circumference, calf length, and thigh length. Italian brands used height and weight, and Japanese brands used height and hip circumference. German brands used subdivided circumferences such as ankle circumference, calf circumference, knee circumference, middle thigh circumference, and thigh circumference.

The purpose of this study was improvement of the pants fit for obese women. The results were as follows; 5 obese women in their 20s and 30s were selected for the testing 3D body. They showed no significant differences in all items, comparing with the data of 5th Size Korea body dimensions. The average waist circumstance of the subjects' 3D body dimensions was 87.0 cm and hip circumstance was 102.4 cm, and their obese body types had similar mean values. Based on the survey results and the 3D body dimensions of 5th Size Korea body dimensions, a pants pattern to supplement their body type and improve a fit was designed with waist circumference(88 cm), hip circumference(103 cm), crotch length(27.1 cm), thigh circumference(62 cm), pants length(97 cm), pants hem line circumference(44 cm). Based on the detailed design of ready made pants and the study results of young obese women's preference for pants design, pants of straight silhouette and semi-tight fit which have waist line lowered by 3.5 cm from the waist circumference line, 3.5 cm belt width, no front dart and one back dart, were manufactured with 100% black cotton and cotton spandex mixed fabrics.

Stretch fabrics are wide-spread for high performance clothing use with requirements of fitness and adaptability to human's movement. A newly developed 100% PET high stretch fabric has excellent properties with respect to stretch, softness, bulkiness, and apparent volume compared to PET filament fabrics. The 100% PET high stretch fabric shows advantages of a dimensional stability, dye and agent adaptability in dying and finishing process, a property of stretch recovery after washing and lower production cost than that of spandex fabric. KES-FB was used to measure mechanical properties to various directions of the fabric. This study centered on whether the 100% PET high stretch fabric is suitable to quality and shape retention of fabric by testing several properties including tensile, compression, shear, bending and surface characteristic to various measuring directions. Tensile linearity showed maximum value at $0^{\circ}$ in plain and $90^{\circ}$ in twill. Shear Stiffness of plain and twill showed maximum value equally at $45^{\circ}\;and\;135^{\circ}$. Bending rigidity showed maximum value at $0^{\circ}$ in plain and $45^{\circ}$ twill. Mean deviation of MIU showed maximum value at $0^{\circ}\;and\;90^{\circ}$ in plain and $135^{\circ}$ in twill.

This study intends to suggest production process of circular knitted jackets and dimensional change data of finished clothes after washing. the study provides pattern design method of circular knitted jackets by applying dimensional change. By doing so, the purpose of this study is to increase production efficiency through accurate order in consideration of loss amount of the fabrics in production. With the three fabric materials selected, this study investigated dimensional change of circular knitted jackets after sewing and washing by varying the parts to be attached to padding cloth and with or without inner lining. As for the fabric F-C (including the spandex, thicker and weightier than the other two fabrics), front width shrunk by 4.6%, which showed the biggest shrinkage among the jackets made of test fabrics. Then it suggested design methods of circular knitted jacket patterns to which dimensional change is applied according to materials, and analyzed the amount of fabric required for production by comparison of the materials. When using the fabric F-C without inner lining, there is big dimensional change and more than double amount of fabric is required. It is expected that the research results will be a basic data for pattern design and production process of circular knitted clothing.

This study investigated underwear consumption behavior of women, who were 20∼59 years old and resided in Incheon during 2002 summer. 372 women completed questionnaires, and data were analyzed using factor analyses, t-test, ANOVA, $\chi$$^2$-analyses. They usually purchased underwear considering comfort and economic factor at a discount store. They wore sleeveless T-shirts, but they didn't wear underpants except panties highly all the year round. Higher rate of them wore pantyhose instead of underpants during autumn, winter and spring. They demanded unstitching of stitches and lengthened sleeves in most of the groups. And older and lowly educated women group wanted widen armhole of upper underwear, and tighten waistband of panties. They generally washed in washing machine using cold water. Besides they added oxygen bleach and softner during wash and final rinse. Older than 20's boil their underwear frequently. The women in a group of boiling commonly answered the looseness of waistband. It is recommended not to boil but to soak with bleach added warm water for improving the whiteness and durability of underwear. For a treatment with higher temperature deprives the elasticity of spandex.
