Seven commercial lining fabrics normally used in a market were selected: plain-weave fabrics with polyester, nylon, rayon and acetate fiber, and polyester textured yarn, in addition, polyester fabrics with plain, twill and satin weave. Then seam strength, seam efficiency, resistance to slippage of yarns and type of seam destruction were examined related to endurance by textiles in sewing capability of the lining fabrics. In results, as tensile strength was greater, seam strength got greater, which shows tensile strength and seam strength have close relationship. Tensile and seam strength of acetate fabric were the least, but seam efficiency was the greatest. It presents that strong tensile and seam strengths do not show high seam efficiency at the same time. Various types of seam destruction have been shown. When tensile strength of the sewing thread was greater than tensile strength of fabric, fabric destruction was occurred before the sewing thread destruction. When tensile strength of the fabric was greater than seam strength, the sewing thread destruction was occurred. Resistance to slippage of yarns got greater as tensile strength of the fabric got greater. The plain-weave fabric, which tensile strength of fabric was smaller, showed the greater resistance to slippage of yarns than twill and satin weave fabrics. The stretch fabric revealed the optimal lining fabric with the greatest resistance to slippage of yarns.

In this article, effect of the dyeing and mechanical properties were investigated on the polyester ultramicro fiber(UMF) and knitted fabric varying fiber fineness(0.01d and 0.05d). By a treatment with NaOH solution, sea-ingredient was removed and polyester micro-fiber was revealed. The dyeing, build-up and fastness properties of the fiber and fabrics were observed. We used C.I. Disperse Red 60 and Blue 56 for dyeing property and eight Lumacron dyes for build-up property and colorfastness. At low temperature dyeing($100^{\circ}C$), the dyeing rate of 0.01d-polyester UME increased more than that of 0.05d-polyester UMF with Disperse Red 60 and Blue 56 whereas dyeing rate of 0.05d-polyester UMF were increased more than that of 0.01d-polyester UMF at high temperature($120^{\circ}C$), The colorfastnesses of the 0.05d-fiber knitted fabric such as washing, rubbing and light was higher than those of the 0.01d-fiber knitted fabric.

The purpose of this study is to fabricate the flame retardant polyester fabric by thermal bonding with low melting component of flame retardant bicomponent filament(LMFRPC) and to describe the characteristics of thermal bonded fabrics. The fabrics were prepared with flame retardant polyester filaments(FRP) as warp and blended filaments of FRP and LMFRPC as weft. The LMFRPC have a sheath and a core wherein the core comprises a flame retardant polyester and the sheath comprises a thermoplastic polyester of low-melting point. In this study, we investigated the physical properties, melting behavior of filament, the effect of the component of FRP and LMFRPC on the thermal bonding, mechanical properties. Melting peak of LMFRPC showed the double melting peak. The thermal bonding of the fabric formed at lower melting peak temperature of bicomponent filament of LMFRPC. The optimum thermal bonding conditions for fabrics was applied at about $170^{\circ}C$ for 60 seconds by pin tenter. On the other hand, the tensile strength, elongation, and LOI of the fabric increased with an increasing component of FRP of weft.

This study investigates the dyeability and fastness of jacquard fabric for blind using low-melting flame retardant polyester. Two types of jacquard fabric were prepared with a low-melting flame retardant polyester and regular polyester. The low-melting flame retardant polyester has a sheath and a core. The core consists of flame retardant polyester and the sheath consists of low-melting polyester. Disperse red 50 (DR 50), disperse blue 56 (DB 56), disperse yellow (DY 54) of E-type dyes and disperse 92 (DR 92), disperse blue 60 (DB 60), disperse yellow (DY 79) of S-type dyes were used and dyed on jacquard fabrics dependent of dyeing temperature and time. The fastness, dye exhaustion, color strength (K/S value), and colorimetric properties of jacquard fabrics were evaluated. The dyeability of S-type dyes were higher than E-type dyes. The experiments indicated optimum dyeability that the dyeing temperature was $110^{\circ}C$ for E-type dyes and $120^{\circ}C$ for S-type dyes for 40 minutes. The fastness to washing and light were excellent at a 4-5 grade.

In order to investigate the detergency effect of stained cotton and PET fabric, respectively, these fabrics stained with solid soils such as carbon black, liquid paraffin, and fat and examined the detergency effect in the optimum washing condition. The evaluation of washing efficiency of washed fabrics studied by using the surface reflectance measurement before and after washing treatment. The maximum detergency effect of stained cotton and PET fabric obtained in the mixed washing liquor-bleachig agen(ml)/concentrated washig agent(g/l). To obtain the excellent detergency effect, 2-step washing treatment, pre-washing by bleaching agent only and washing by concentrated detergent, is preferred. In comparing the detergency of polyester and cotton fabric, the detergency of stained polyester fabric superior than that of stained cotton fabric because of the difference of adhesive force between soil material and fabric in preparing soled stained fabric. In this study, we also studied the degree of fabric damage by the measurement of tensile strength change. From the results of the tensile strength measurement, the damage of washed fabric before and after washing treatment was nearly changed.

The purpose of this study was to examine the effects of chemical finishes on performance characteristics of microfiber blend fabrics. A 60% polyester microfiber /40% cotton blend woven fabric was finished by ten chemicals: three silicone softeners, one fluorochemical, and their mixtures. Performance characteristics examined were fabric hand attributes. Fabric hand was evaluated by instrumental measures using Kawabata KES-F system instruments. Silicone-only finishes did not change the bending properties significantly from those of the control fabric. The fluorochemical-only finish made the fabric stiffer and crisper. When the two chemicals were mixed they tended to offset this adversary effect. Most of the chemical finishes made the surface finer and smoother. Fluorochemical-only finish improved fabric strength. Likewise, dimethylpolysiloxane silicone improved fabric strength. Amino-functional hydrophilic and diamino-functional silicone softeners, on the other hand, reduced fabric strength. However, when mixed with the fluorochemical, the adversary effect was diminished.

Cotton, P/C and polyester fabrics were laundered and treated with 4 kinds of aftertreating agent(antistatic and softening agents) on marketing. Some treating condition:. which include agent concenteration, treating time and rinsing extent after laundering, were varied. And then the effects of agents with each treating condition-handle value, charged voltage and half-life, and crease recovery etc.-were determined and discussed about their change. The improvement of handle and antistatic properties by treatment were indicated remarkably for cotton fabric and P/C and polyester fabrics respectively. Generally, the handle value of cotton was decreased and then increased again, and the charged voltage and half-life of P/C and polyester fabrics were decreased with increase of concenteration of agents. The effect of antistatic improvement for P/C fabric was larger than polyester fabric at even lower concenteration of agents. The effects were increased with treating time and rinsing extent. In particular, those of short time(1 minute) treatment were very small.

Microwaves are high frequency radiation capable of generating very rapid, uniform and efficient heating of textile material. Microwave heated dyeing of polyester fabric was tried with different solvent systems, irradiation time and dye concentration. Microwave fixation methods were used with 100% water,30% urea, EG and DMF, respectively, pad-baths in which the padded fabrics were exposed over a heated or boiling water bath to maintain sufficient moisture content during irradiation. In order to ascertain the relation between the dyeing property of polyester fabric and the microwave irradiation condition caused by microwave heating, the K/S values and fastness properties of dyed fabrics such as light, washing and sublimation fastness were measured.
