The subjective hand and preference of alkaline hydrolized polyester fabrics were evaluated using the scale developed. The factors affecting consumer's taste for polyester fabrics was analyzed by the statistical technique. The effects of alkaline hydrolysis on the properties of polyester fabrics were evaluated by subjective and objective hand measurements. The lower the age the more senstive their feeling. As the age of evaluators decreased they felt fabrics light flexible refined thin flossy smooth fine soft more clinging. They also thought fabrics are colder, more flexible more spongy as the age increased. Experts were more sensitive and consistent when they evaluation the hand of fabrics than non-experts.

We investigated the effects of the fabric structure or the kinds of plated metals on the electromagnetic interference shielding effectiveness (EMI SE) by means of electroless plating on polyester fabric. We found that the weight of deposited metal, EMI SE, and flexibility of the conductive fabric for EMI shield is affected by morphology of fabric and structure of fiber. The EMI SE of conductive fabric plated Ni/Cu/Ni by electroless plating method on draw textured yarn (DTY) polyester was in the practically useful range of above 70 dB over a wide frequency range of 10 MHz to 1.0 GHz at the surface resistivity of $0.05{\Omega}/{\square}$. Au or Ag plated conductive fabric by immersion plating method is not able to provide for a good EMI SE.

This study discussed the mechanical properties such as bending and shear of polyester fabric treated with a several weight reduction machine. With the increase in the rate of weight loss, the bending rigidity of the warp and weft of treated fabric decreased regardless of the weight reduction machine. At 6.5% weight loss, the bending rigidity of warp and weft yarn decreased to $0.035\;gfcm^2/cm$ and $0.017\;gfcm^2/cm$, respectively, and these values show 54% and 94% of their untreated warp and weft. At same rate of the weight loss, the bending rigidity of polyester fabric treated with C.D.R slightly higher than that of the tank type or liquor-flow type. On the other hand, below 6.5% weight loss, the shear rigidity of the warp and weft of the treated fabric rapidly decreased. But with the increase in the above 6.5% rate of weight loss, the decreasing tendency of the shear rigidity declined. At same rate of the weight loss, the shear rigidity of fabric treated with tank type nearly equal to the that of the liquor flow type. But at same rate of the weight loss, the shear rigidity of the fabric treated with C.D.R type higher than that of the tank or liquor-flow type.

The dyeing property of direct-spinning type and seaisland type 0.2D micro polyester nonwoven fabrics was characterized by three disperse dyes (Dorosperse Red KFFB, Blue KGBR, Yellow KRL) at $120^{\circ}C$ and $130^{\circ}C$. Before and after reduction cleaning, dyeing fastness was evaluated and the thermomigaration after heat setting at $180^{\circ}C$ for 60 min were also evaluated. Direct-spinning type fabric showed better dyeing property, wash fastness, and light fastness, but worse rub fastness than seaisland type fabric. The dyeing property and fastness of direct-spinning type fabric increased at higher dyeing temperature, whereas seaisland type fabric exhibited lower dyeing fastness and the increase of thermomigration at higher dyeing temperature. Non-fixed dye in fiber surface was removed by reduction cleaning process, then dyeing fastness was improved and thermomigration decreased. The higher dye uptake of direct-spinning type non-woven fabric caused the increase of dye molecule migration from fiber internal to fiber surface, so this fabric showed larger thermomigration than seaisland type non-woven fabric.

This study examined the effect of the blend ratio of wool and polyester fibers, yarn and fabric structural parameters to the appearance property and the formability of worsted fabrics. The mechanical properties of twenty types of manufactured worsted and PET/wool blend fabrics were measured using KES-FB and FAST systems. Garment formability increases with the thickness and cover factor as well as increases with wool content. The correlation between KES-FB and FAST system showed a relatively high correlation with an extensibility of 0.98, bending and shear rigidity 0.71; both were higher than polyester synthetic fiber. The correlation coefficient of garment formability between KES-FB and FAST systems was 0.93 and the correlation coefficient between formability and fabric extensibility was 0.8. These results were higher than those of bending and shear rigidity. This revealed that garment formability was influenced by wool content, cover factor and fabric thickness; however, wool content and fabric thickness were the most important factors for the seam pucker. The garment formability of the worsted fabrics can be predicted by fabric mechanical properties measured from KES-FB and FAST systems.

The purpose of this study is to analyze the dyeability of polyester(PET) fabric by thermal bonding with low melting component of bicomponent fiber and to describe the change of physical properties of thermal bonded PET fabrics. The PET fabrics were prepared with regular PET fiber as warp and bicomponent fiber as weft. The bicomponent fiber of sheath-core type was composed with a regular PET core and low melting PET sheath. The thermal bonding of PET fabric was carried out in pin tenter($195^{\circ}C$) for 60 seconds. In this study, we investigated the dye ability and fastness of the dyed PET fabric. Dye ability of E-type dyestuff is higher than S-type dyestuff. In the case of E- type dyestuff, the saturated dyeing time was 10minutes at $130^{\circ}C$. The washing fastness and light fastness were excellent as 4-5grade.

Polyester microfiber has usually greater dye uptake than normal denier polyester fiber in same dyeing condition. In spite of this high dye uptake dyed microfiber fabric has not only low visual colour depth but also poor washing fastness property. In order to study high colouring dyeing technology and high washing fastness of polyester microfiber, dyeing property of polyester microfiber was investigated according to the dye solubility and particle size of used disperse dyes in aqueous dye solution. After disperse dyeing, dyed fabric with disperse dye was redyed with a vat dye without reduction clearing in order to obtain a high washing fastness property. The result were as followings ; A small particle sized disperse dyes such as C. I. Disperse Blue 56 and Red 60 showed high rate of initial exhaution compared with a large particle sized disperse dyes like C. I. Disperse Blue 165 and Red 343. In study of dyeing property of polyester microfiber with C. I. Vat Blue 1, polyester microfiber could achieve high dye uptake at a given optimum vatting process conditions. On the other hand, in consecutive dyeing with disperse and vat dye, K/S value of polyester microfiber with a small particle sized disperse dye increased without reduction clearings, but K/S value of polyester microfiber with a large particle sized disperse dye decreased with reduction clearings.

This study was carried out investigate the characteristics of Habutae and Chiffon woven with silk and polyester(S/P) compound yarn. The S/P compound yarn could be produced by the automatic reeling machine with attachment of air jetting device, polyester yarn guider and tension control apparatus. The surface structure, tensile property and dyeing fastness of S/P compound fabric were examined for the fabric properties. Electron microscopy revealed that most part of S/P compound yarn was well interlaced and some silk part of compound yarn were hidden by polyester on an examination of surface of chiffon fabric. By the one bath and two step dyeing of disperse and acidic dyes, the colour fastness of S/P compound fabrics were 4 grade above. The tenacity and initial modulus of the finished S/P compound fabric were lower than those of grey and degummed fabrics, but reversed in elongation.

Diphenyl-2-ethanolamidophosphate (DPEOAP) was synthesized to treat polyester fabrics in order to improve its flame retardancy. The flame retardancy and physical properties of DPEOAP-treated polyester fabrics were investigated. The results were as follows: 1) polyester fabrics can be treated with DPEOAP by means of Pad-Dry-Cure method, because DPEOAP was easily soluble in benzene. 2) The most economic conditions of treatment were determined as 10% of DPEOAP cocentration, $140^{\circ}C$ of curing temperature, and 2 minutes of curing time. 3) Though the washablity of DPEOAP is low in comparison with the other products which are purchasable in a market, it has an excellent flame retardment effect 3 times more than in number of flame contact just with 0.66% add-on. 4) The physical properties of DPEOAP treated polyester fabrics were little changed as compared with non-treated fabric.

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 abrasion resistance, and oil/water repellency. Chemical finishes containing dimethylpolysiloxane silicone performed better in fabric abrasion resistance than other chemicals. The correlation between abrasion wear and instrumental measures of fabric hand indicated that the breaking strength loss by abrasion related negatively to the coefficient of friction. This implied that the finished fabrics with lower surface frictional coefficient (slipperier) had higher breaking strength loss by abrasion. The microfiber structure of polyester did not appear to help in oil/water repellency due to the larger surface areas of the microfibers. The fluorochemical finished fabric had the most significant improvement on oil/water repellency. The silicone-only finishes, however, did not improve oil/water repellency. When mixed with the fluorochemical, silicone finishes showed improved oil/water repellency.
