This study was carried out to investigate the effects of dyeing on the mechanical properties, primary hand, total hand value (THV), and total appearance value (TAV) of woven fabrics. Cotton, PET, nylon, cotton/PET, and cotton/nylon woven fabrics were used as test specimens. Each of fabric was dyed under the same conditions as the fabrics for sportswear which consumers have selected as best. Mechanical properties of specimens were measured by KES-FB system and primary hand and THV were calculated by equation KN -201-MDY and KN-301-WINTER respectively. TAV was calculated by KN (eq. 10). The results were as follows: 1. In mechanical properties. tensile energy increased when cotton and two cotton mixture fabrics were dyed and decreased when polyester and nylon fabrics were dyed. Bending rigidity and shear rigidity decreased after all fabrics were dyed except nylon and cotton/ nylon mixture fabrics showing higher rigidities. Cotton fabrics showed higher surface roughness while other fabrics did lower values after dyeing. 2. In evaluation of primary hand and total hand , four primary hands of cotton fabrics so decreased after dyeing that THV were lowered. Numeri, Fukurami, and Sofutosa in primary hand of polyester, cotton/polyester, and cotton/nylon fabrics and Koshi and Numeri of nylon fabrics increased after dyeing and therefore THV of four fabrics were improved. 3. Cotton and polyester fabrics showed higher TAV due to their lower bending and shear rigidity, while nylon and cotton/nylon fabrics did lower values due to their higher shear rigidity. 4. It was proposed that the method of dyeing or treatment for minimizing the decrease of THV of cotton fabrics and TAV of nylon fabrics should be developed.

The ability of inherently conducting polymer (ICP) coated textiles to recover gold metal from aqueous solutions containing $[AuCl_4]^-$ was investigated. Nylon-lycra, nylon, acrylic, polyester and cotton were coated with a layer of polypyrrole (PPy) doped with 1,5-naphthalenedisulfonic acid (NDSA), 2-anthraquinonesulfonic acid (AQSA) or p-toluenesulfonic acid (pTS). Textiles coated with polyaniline (PAn) doped with chloride were also used. The highest gold capacity was displayed by PPy/NDSA/nylon-lycra, which exhibited a capacity of 115 mgAu/g coated textile, or 9700 mgAu/g polymer. Varying the underlying textile substrate or the ICP coating had a major effect on the gold capacity of the composites. Several ICP coated textiles recovered more than 90 % of the gold initially present in solutions containing 10 ppm $[AuCl_4]^-$ and 0.1 M HCl in less than 1 min. Both PPy/NDSA/nylon-lycra and PAn/Cl/nylon-lycra recovered approximately 60 % of the gold and none of the iron present in a solution containing 1 ppm $[AuCl_4]^-$, 1000 ppm $Fe^{3+}$ and 0.1 M HCl. The spontaneous and sustained recovery of gold metal from aqueous solutions containing $[AuCl_4]^-$ using ICP coated textiles has good prospects as a potential future technology.

본 연구는 자동차 파쇄 잔재물의 활용성을 알아보고자 폐차과정에서 발생되는 폐나일론 섬유를 아스팔트 콘크리트에 첨가하여 일반 아스팔트 콘크리트와의 피로수명 비교, 경제성 분석을 실시하였다. 4점 휨 피로 시험을 수행한 결과 일반 아스팔트 대비 피로수명이 10% 향상되었으며, 이를 통해 경제성 분석을 실시하여 35년간 약 5.4억 원의 유지보수비용에 대한 비용 절감을 가져 오는 것으로 확인 되었다. 폐나일론 섬유 보강 아스팔트는 비용절감 효과와 더불어 폐자재의 환경처리비용 이점과 활용성 측면에서의 친환경적 공법으로 생애주기비용분석에서보다 더 큰 경제적, 사회적 효과가 발생 할 것으로 판단된다.

This study is the high contraction processing conditions set by the method of the CPB process. And the ultimate goal of this study is the high contraction of the CPB processing test method that can solve the problems of the high-contraction fabric processing method of the current jet dyeing machine. Non-coating process(CPB process) developed by the expression of a soft touch, light weight, functional and to develop excellent breathable nylon fabric. The nylon fabrics established the optimum processing conditions through the high contraction of the various test conditions, the CPB system.(The benzyl alcohol was used as the main constrictor.) At this time, the warp and weft contraction of nylon fabric was about 20%. And it established the constrictor concentration, the treatment temperature, time of a variety of tests. Also non-coating process(CPB process) can develop soft touch, lightweight, excellent air permeability. As a result, we developed a high contraction nylon fabric having a uniform surface. Manufactured fabric is used for Wind-proof and Down-proof.

This study aimed to determine the physical properties of silk and nylon fabrics that are treated with persimmon juice in accordance with irradiation time of ultraviolet spectrum. Persimmon juice dyeing has the advantage of using the tannin component of the persimmon. Tannin plays an important role in inhibiting photodegradation of fibers or polymers. Among fibrous materials, silk and nylon are prone to deterioration by light. Hence, this study aimed to reduce these weaknesses of silk and nylon by applying persimmon juice treatment. We accordingly carried out investigation and experiments on ultraviolet irradiation, and physical characteristics of treated fabrics. The persimmon juice treatment process led to increased weight and thickness. In addition, the air permeability of silk fabric was increased, as compared to the control specimen; whereas, that of nylon fabric was decreased. Both drape stiffness and flex stiffness of silk and nylon tended to be high in textiles processed with persimmon juice treatment, as compared to the control textile. Peak load and elongation at peak load of untreated samples clearly decreased in both silk and nylon fabrics with the increase of ultraviolet irradiation time, while those of persimmon juice treated samples increased. Furthermore, ultraviolet blocking ratio measurement indicated that the fabric specimens treated with persimmon juice blocked U.V. spectrum better than the control specimen.

In this study, the dyeability of natural dye extracted from chesnut shell was investigated in order to explore the using of discarded chesnut shell in natural dyeing. Dyeing experiments were done in various dyeing conditions which were different in dyeing temperature, concentration of dyebath, dyeing time, repitition of dyeing. pH of dyebath and mordant with 3 kinds of experimental fabrics silk, nylon and cotton. Color and color difference ($\Delta$ E) of every dyed fabrics were measured and color fastness to drycleaning, washing, perspiration and light were measured. The results were as follows ; 1. The dyebath became thicker with time and temperature of extraction and the characteristics of dyebath prepared chesnut shell 1g : distilled water 30㏄ after 3 hrs-boiling were 32,400ppm and 3.7pH. 2. The dyeabilities of silk and nylon fabrics were good and color difference was increased with dyeing temperature, concentration of dyebath, dyeing time, number of repitition and acidity of dyebath. But the dyeability of cotton was very poor compared to silk and nylon. 3. Without the treatment of mordant, the dyeability of silk was little lower than that of nylon, but after the treatment of mordants it became higher than nylon. After the treatment of mordant Cu and Fe, the dyeability of cotton was increased although the natural dye from the chesnut shell was hardly absorved in cotton without mordant. 4. On the whole, the colorfastness of dyed silk and nylon were very good except the colorfastness to washing in silk and the colorfastness to light in nylon.

Highly conductive polyaniline(PAn)-nylon 6 composite fabric was prepared by immersing the nylon 6 fabric in 0.5M aniline+0.35M HCl aqueous solution at 4$0^{\circ}C$ for 2hours, Polymerization was then followed by mixing the prepared oxidant and dopant solution(0.5M(NH4)2S2O+0.35M HCl) to the diffusion bath at 5$^{\circ}C$ for 30 minutes. The conductivity of prepared PAn-nylon 6 composite fabrics reached as high as 0.5$\times$10-1S/cm. Their conductivity were significantly affected by the aniline and oxidant concentration. As compared to those of nylon 6 fabric heat of fusion melting point the degree of crystallinity and tensile strength of PAn-nylon 6 did not significantly changed by inclusion of PAn. In the aspect of serviceability wheras the fabric conductivity was significantly decreased after multiple washion no significant changes in the fabric conductivity were observed after abrading the composite fabric over 50 cycles. However we found that the fabric conductivity could be recovered by acid re-doping with HCl.
