  • This study surveys the tension differences between Korean domestic and foreign looms and analyses fabric mechanical properties due to warp and weft tension differences using KES-FB system. Paper is divided by two parts. In this 1st paper, fabric is designed as 5 harness satin weave using 75d/36f warp and 100d/192f weft polyester filaments, and is woven by $Omega^\circledR$ rapier loom by Textec Co.Ltd and Picanol$-GTX^\circledR$ rapier loom by Picanol Co.Ltd respectively. These grey fabrics are processed on the same dyeing and finishing processes. Weavability is also analysed by measuring warp tension variation according to the warp position, the relationship between shed amount and the warp tension on one fixed heald frame is surveyed, and the relationship between end breaks and warp and weft tensions is also discussed.

  • In order to investigate the changes in mechanical properties of sanitary nonwoven fabrics actually used as a top sheet, the fabric was treated with a mixture of chitosan and nanosilver colloidal solution in accordance with the prescribed ratio. The former is a natural polymer with excellent biocompatibility and the latter can give an additional performance while compensating the weaknesses of chitosan of deteriorating adherence efficiency. It was shown that the bending and shearing characteristics of the chitosan/nanosilver treated fabrics decreased, which helped to make it softer, smoother and more flexible. The shape stability and drapability of the treated fabrics improved. As KES-FB system evaluation showed that Koshi was deduced, and both Numeri and Fukurami were increased. Thereby, the chitosan/nanosilver treated fabrics were smoother to provide elasticity. In the change of hand value compared to chitosan only treatment, a better THV was shown in the fabrics treated with chitosan/nanosilver mixed solution than the fabric treated with chitosan alone.

  • The main purpose of the study was to investigate relationships between subjective evaluation of comfort/discomfort and tactile sensation. It was also attempted to analyse physical properties of fabric, hence to find physical factors which have effects on wearing- comfort. The results were as follows; 1. Polyester fabric B Type ranked the highest on subjective comfort scale of T-shirts. 2. Scratchiness and flexural rigidity among subjective factors were important on overall comfort sensations of the subjects. 3, In winter, subjective factors, suchas Soratchiness, Heaviness & Flexural Rigidity, were significantly correlated with objective factors of Scratchiness, Thickness & Weight, Stiffness, respectively. 4. In summer, subjective factors such as warmth, Heaviness, Clammy & Cling Tension, Flexural Rigidity, were significantly correlated with objective factors of Thermal Insulation, Thickness & Weight, Cling Tension and stiffness, respertively. 5. Scratchiness, Weight, Stiffness & Thermal Insulation among objective factors were important on overall comfort sensation of the subjects.

  • To improve the physical properties and the dyeing properties of silk, the silk fabric was treated with urea resin and reactive dyeing. The effects of urea resin concentration, pH of padding bath and curing condition were investigated in order to find optimum condition and the following results are obtained The optimum condition for the crease recovery of silk fabric was urea resin concentration of 80 g/ι, pH of 7, the curings temperature of about 135$^{\circ}C$, and the curing time of 3 minutes. The crease recovery and the thermal insulation ratio of silk fabric were increased by the above treatment. K/S increased as the adding amount of Na$_2$SO$_4$ increased, K/S, however was not affected by the adding amount of Na$_2$CO$_3$. Co1or fastness of the dyed fabrics treated with urea resin were improved slightly compared with untreated ones.

  • Fabric hand was assessed for 14 women's spring-fall dress fabrics based on the subjective hand evaluation scale developed in the part 1 of this study. The effects of fabric type, seam and dress style on the subjective hand evaluation of 470 Korean consumers (205 textile experts and 265 non-experts) were investigated. Mechanical properties obtained from KES-FB system were compared with the each dimension of subjective hand expression. The type of fiber and construction were considered to be important factors in affecting hand assessment of Korean consumers, however, the presence and type of seam were not considered to be important. There were certain characteristics of subjective hand attributes for each dress style. Surface properties of fabrics, even though it is not strictly mechanical properties, appeared to be the most effective dimension in the developement of new products which appeal to Korean conssumers.

  • We have measured viscoelastic properties of fabrics in thickness direction. We assume that Maxwell model is very useful in stress relaxation of viscoelastic theories and appropriate formulas for fabric are calculated. Measurement system constitute of high precession load cell, translator and laser displacement sensor for viscoelastic properties was designed and elastic coefficients and damping coefficients were measured for 10 fabric samples. Elastic coefficients measured were 19~25 kN/㎡ and Damping coefficients measured were 4.8~8.7 MN$.$s/㎡. We concluded that these coefficients are good related with FUKURAMI collected from KESF system

  • The Purpose of this studs was to investigate dyeing properties of silk and nylon fabrics by Polygonum cuspidatum extract. The properties were evaluated by it's extracting condition, dyeing condition, mordants variables, methods of mordanting and color fastness. Silk fabric showed the highest K/S value at $50-70^\circ{C}$, while Nylon fabric showed at $90^\circ{C}$. Surface color of dyed fabrics were various by the used mordants ; none-, and Al-mordanted fabrics were yellow, Cu-mordanted fabrics were redish yellow, Fe-mordanted fabrics were olive green. Fe-mordanted silk fabrics showed excellent laundering fastness and light fastness. Both silk and nylon fabric showed excellent laundering and dry cleaning fastness.

  • Electroconductive fiber was obtained by acryl fiber treated with $CuSO_4$. The Properties and structure of fiber and fabric such as mechanical property, electrical conductivity, fine structure, electrification were investigated. The experimental results are as follows 1) The electrical conductivity of the conducting fiber was greatly increased but fine structure and physical properties were similar to acryl fiber 2) Fabric made by mix spinning with conducting fiber was shown great electrification effect. 3) In the mix spinning with conducting fiber, it was necessary to use different. finishing such as milled finish because stiffness of fabric made by mix spinning with conducting fiber was increased and elastic recovery was decreased. 4) The antimicrobial activity of electroconductive fiber blended wool was effective by Cu component for shake flask test.

  • As a series of the studies of thin rubber coated fabrics, the experiments were concentrated on the investigation of the physical properties of the surface and back coated fabrics with natural and synthetic rubber. Cotton poplin and nine other cotton shootings were used as a base fabric and both sides of fabric, face and back, were coated by means of topping or spreading process. The physical properties of finished material were broadly investigated especially in view of the quality requirements of the poncho.
