In order to investigate the dyeing property of poly trimethylene terephthalate(PTT) fabric, the dyeing of PTT fabric was carried at under condition of different dyeing temperature by using several disperse dyes with different energy level. Particularly, this study discussed the PTT dyeing thermodynamically. Used disperse dyes were selected based on the their chemical structure and energy level. The obtained results were as followings; The dye adsorption of S type disperse dye such as C. I. Disperse Blue 79 increased with increasing dyeing temperature. In a exhaustion rate of PTT fabric with disperse dyes, C. I. Disperse Blue 56 showed higher values than that of C. I. Disperse Orange 29 and Blue 79. For the interpretation of thermodynamic dyeing behavior, the partition coefficient ( K ) and some several thermodynamic parameters such as standard affinity$(-\mu^\circ)$ and heat of dyeing$(\Delta{H}^\circ)$ calculated from the adsorption isotherm. From above results, as the energy level of disperse dye is small, the partition coefficient and standard affinity increased. But the heat of dyeing of PTT fabric with disperse dye showed high negative value in order of E type(C. I. Disperse Blue 56), SE type(C. I. Disperse Orange 29) and S type(C. I. Disperse 79).

This study explicates some properties of the fabrics used in the 16th century by examining and analyzing the 90 pieces of fabric excavated from the graves of Mr. Ryu of Jinju and his wife Mrs. Park of Euiin. The fabrics were classified into silk tabby(紬), thin silk tabby, satin damask(段), complex gauze(羅), mixture fabric with silk and cotton(絲棉交織), cotton(棉布) etc. Compared to other contemporary fabrics excavated previously, the fabrics unearthed from the couple's graves presented very naive feelings. Patterned satin damask occupied a small portion. In the case of plain fabric, little filament silk tabby(絹) or thin filament silk tabby(細紬) was unearthed. Important data on the history of Korean costumes are provided by the noteworthy, first-ever excavation of a small cap made of complex gauze(羅) and the tiger-leopard embroidered patches called hyoongbae(胸背), which were worn on the front and back of official robes made of tabby with supplementary gold thread(金線). Only 3 pattern types could be clearly identified in form, cloud pattern, lotus and vine pattern(蓮花蔓草), and small flower and treasures pattern(七寶細花). These three patterns are very similar to those of other 16th century fabrics unearthed previously in terms of the form and arrangement of patterns.

This study was conducted based on a comparative analysis of design-specific features prevalent in the Women's Wear Collection S/S 2011. As the method of this study, the denim styles were classified by various fashion design factors consisting of silhouette, fit, color, and textile fabric, which were extracted from an image database. The properties of denim fabrics associated with each fashion image were investigated to inform fabric development and washing. The results of the study show that the dense and glossy surface of the denim fabric represent a modern trend, which can be achieved by blending lyocell, tencel and rayon or by using different textiles, such as lightweight plain weave and satin instead of twill. For casual look, various washing effects were utilized jean's casual feeling like freedom and activities, while in a modern image, washing effects was restricted. And a glossy textile offers a simple modern look. The Modern image represents a simple H-silhouette and wide or straight fit in bottoms as well. Brightness can be adjusted by washing-induced bleaching. High brightness gives an elegant image, while low brightness makes a casual image. The purpose of this study is to configure a database for the development of design in the growing women's casual wear market. In addition, This study, in which the elements for specific fashion image-making were analyzed, can be used as a reference for developing denim style and fabric.

Shrink resist finishing of wool fabric was carried out with Monoethanol aminesulphite (MONAMIN BTN) shrink resist agent after chlorination with Dichloro isocyanuric acid (DCCA). The purpose of this study is to investigate the effect of treating conditions, such as concentrations of DCCA and MONAMIN BTN, pH of treating bath, dyeing times, curing times and temperatures, on dyeing property of wool fabrics. K/S values and fastness properties of dyed wool fabrics were measured. The K/S values of dyed fabrics were increased gradually with increasing concentration, and decreased with increasing curing time. The optimum dyeing time and curing temperature were 60 min and $140^{\circ}C$, respectively. Also it seems likely that the shrink resist finishing carried out at 3% (o.w.f.) of MONAMIN BTN and pH 7 of resin treating bath is effective in increasing K/S values. Light fastness of fabric dyed was very poor and the fastness of fabric dyed was not influenced by the treatment conditions.

Split-type nylon/polyester microfiber and polyester microfiber fabrics possess drapeability, softness, bulkiness, and smoothness, so that they can be applied in various industrial fields. In particular, these fabrics are able to absorb various organic solvents, and can be used as clean room materials. To investigate the chemical affinity between solvents and the compositional materials of these fabrics, the contact angle of thermally pressed film fabrics was measured with different solvents. The thermally pressed nylon/polyester fabric films showed a chemical attraction to formamide. The sorption properties of the microfiber fabrics were investigated using a real time testing device, and these tests showed that the sorption behavior was more influenced by the structure of the fibrous assembly than by any chemical attraction. The effect of the fabric density, specific weight, and sample structure on the sorption capacity and rate was examined for various organic solvents. The sorption capacity was influenced by the density and the specific weight of the fibrous assembly, and knitted fabric showed a higher sorption capacity than woven fabric. However, the sorption rate was less affected in lower viscosity solvents. On applying Poiseuille's Law, the lower viscosity solvents showed higher initial sorption rates, and more easily penetrated into the fibrous assembly.

Two kinds of nylon 6 fabrics with different fiber denier, such as ultramicro fiber(UMF) nonwoven fabric(monodenier 0.05d) and regular fabric(monodenier 2.92d) are dyed with C.I. Acid Red 18(leveling type) and C.I. Acid Blue 113(milling type). Dyeing rates and adsorption isotherms are measured at $60^\circ{C}$, pH 5.0 and at liquor ratio of 1 : 250. To investigate the effect of fixing agents (Matexil FA-SNX, Monorex-RD and Tinofix-ECO) on UMF nylon 6 nonwoven fabric, dyeing is carried out at 3~10% owf with 1 : 2 metal-complex acid dyes, such as Kayalax Navy R(unsulphonated type), Lanasyn Blue S-BL(monosulphonated type) and Kayakalan Black BGL(disulphonated type). The dyeing rate of UMF nylon 6 is faster than that of regular nylon 6. From the results of absorption isotherms, the regular nylon 6 has higher saturation value of Acid Red 18 compared with UMF nylon 6, whereas UMF nylon 6 has higher saturation value of the acid Blue 113. From the absorption isotherms of both acid dyes, the regular nylon 6 has higher saturation value of Acid Red 18, whereas UMF nylon 6 has higher saturation value of the acid Blue 113. The wash fastnesses of UMF nylon 6 increases in the order of metal-complek dye containing nonsulphonated group > monosulphonated group>disulphonated group. Aftertreatment of UMF nylon 6 dyed with unsulponated and monosulphonated dyes improves wash fastness upto grade 1.5, where as that of UMF nylon 6 dyes with disulphonated dye does not improve wash fastness.

본 연구에서는 의복 착용 시 직물이 스치면서 발생하는 왕복마찰음에 대한 물리적 소리특성과 주관적 감각을 고찰하기 위해, 왕복운동을 이용한 직물마찰음발생장치를 개발하고 이 장치를 이용하여 5가지 직물의 왕복마찰음을 녹음한 후, 총음압(LPT), 음압차(${\Delta}L$), 주파수차(${\Delta}f$)를 계산하였다. 왕복마찰음에 대한 주관적 감각은 7개의 소리감각(부드러움, 시끄러움, 날카로움, 맑음, 거침, 높음, 유쾌함)에 대하여 의미미분척도로 평가되었다. 나일론 태피터와 폴리에스테르 레노 직물의 왕복마찰음은 높은 LPT를 나타내어 시끄럽고 날카롭고 거칠며 불쾌한 소리로 인지되었다. 반면 LPT와 ${\Delta}f$의 값이 작은 폴리에스테르 울트라스웨이드와 실크 크레이프드신 직물의 왕복 마찰음은 부드럽고 조용한 소리로 평가되었다. 마찰방향(왕복 방향, 한 방향)에 따른 직물의 마찰음 비교시, 왕복 방향 마찰음은 한 방향 마찰음보다 더 날카롭고 시끄럽고 거칠게 인지되었으며 마찰방향에 상관없이 LPT가 소리감각을 예측하는 중요한 요인으로 나타났다.

In this paper, an analytical model for the prediction of the elastic properties of multi-axial warp knit fabric (MWK) composites is proposed. The geometric limitation, effect of stitching fibers and design parameters of MWK composites are considered in the model. The elastic behavior of MWK composites was conducted by using an averaging method. The predicted elastic properties are in reasonably good agreement with experimental values. Finally the effect of stitching in the MWK composites are discussed.
