The aim of this study is to enhance the abrasion of the hydrolyzed polyethylene terephthalate(PET) fabrics by using microwave energy. In other to achieve the aforementioned objectives, PET fabrics were hydrolyzed in NaOH solution by using abrasion method such as dipping, microwave-dipping, pad steam-dry, and pad microwave-dry, and then abrasion of the hydrolyzed PET fabrics was calculated and investigated. As a result obtained form this study, the abrasion of the hydrolyzed PET fabrics is directly proportional to hydrolyzed time and NaOH concentration. And also, microwave-dipping method and pad microwave-dry method showed remarkable abrasion effect than the others.

Skin patch test and antibacterial properties of the reaction products between poly(hexamethyl biguanide) hydrochloride and trimethylol melamine on textile fabrics were examined. Antibacterial activities of anti-microbial agent treated samples are very good. The reduction ratios against four kinds of colonies are 99.9 % after repeated laundering ten times. Skin patch test results for anti-microbial agent treated samples are almost-negative by Hi-scope judgement and macroscopical judgement.

The effect of sodium acetate to reduce the fiber damage and hardening of acetate fabrics during alkaline treatment is studied. The optimal condition is controlled concentration 2%, at $50^{\circ}C$ for 6 minutes and at $70^{\circ}C$ for 2 minutes through the result of weight loss, shrinkage and tensile strength. Alkaline treated acetate fabrics under optimal condition show softer than untreated acetate fabrics. Alkaline treatment with sodium acetate brings the reduction in hardening and shrinkage in internal fiber of acetate fabric. Also, alkaline treatment with sodium acetate improves the tensile strength of acetate fabrics compared with only alkaline treatment. The moisture regain of acetate fabrics is also improved by alkaline treatment under optimal condition.

The purpose of this study was to develop the High Functional Stretch Yarns and Woven Fabrics to produce the high value added textile goods and to meet the consumer's needs. For the study 8 yarns and 10 fabrics were made with three develop machine and the thermal-stress properties of the sample were tested and analysed. The result indicated that the sample fabrics kept their stretch performance regardless of conventional process. EDY(elastic DTY) had higher stretch than that of DTY(drawn textured yarn). Especially Macel yarn had higher stretch than that of DTY compared with the same condition of yarn. With time course behavior the elongation of DTY and EDY had stabled tendency without variation. The above results show that wearing sensation and comfort properties of fabrics are changed depending on the end-use. and thus, above results can be used to manufacture of fabrics for specific end-use with high comfort properties.

In this study it was measured seam strength of T/C which has the different processing methods and density. Also it was measured seam strength by the change of angle in the pattern and the kinds of threads. The results of this study are as follows; The seam strength is stronger in order of $90^{\circ}/90^{\circ}$ > $0^{\circ}/0^{\circ}$ > $70^{\circ}/-70^{\circ}$ > $70^{\circ}/70^{\circ}$ > $60^{\circ}/60^{\circ}$ > $60^{\circ}/-60^{\circ}$ > $30^{\circ}/30^{\circ}$ > $30^{\circ}/-30^{\circ}$ > $45^{\circ}/-45^{\circ}$ > $45^{\circ}/45^{\circ}$ by the cutting directions, in order of T/C3>T/C1>T/C4>T/C2 by the samples and in order of 60's/3>40's/2>60's/2>50's/2 by the threads.

Wool fabrics were treated with dichloro isocyanuric acid (DCCA) and dyed with acid dyes (C.I. Acid Red 18), and then, they were treated by sputter etching. Wool fabrics had been sputtered with aluminium under various conditions such as sputter etching time and discharge power in the presence of argon gas. We compared mechanical properties, colour difference and fastness properties of these samples one another: Mechanical properties and colour difference of sputtered wool fabrics changed by sputter etching time, discharge power and DCCA concentration. Light fastness showed a rising tendency but rubbing fastness showed a downward tendency when sputter etching time was 7 minutes.

We studied on the softness properties of polyester fabric by vapor type ozone processing using ozone's strong oxidation instead of 25% NaOH chemical treatment. When vapor type ozone processing was directly treated to fabrics retaining water to 40% pick up ratio, high concentration ozone was generated oxidation of 3~4% approximately in polyester fabrics and finally its softness improved. The fabric's softness effect was improved because vapor type ozone generated the highest decomposition to oxidation of surface and inter molecules. The experiment revealed that fabric's softness was improved by change of the time of vapor type ozone processing. However, tensile strength and elongation were reduced by increase in time, 60 minute was assumed as the most optimized time to minimize the reduction of fabric's tensile strength and elongation as well as maximizing the fabric's softness.

This paper is concern with the effect of various conditions on mechanical properties of textile fabrics by water soluble resin treatment. Resin treatment of cotton, acetate, viscose rayon, polyester, nylon and acryl fabrics were made by aqueous resin treatment to improve the mechanical properties. The mechanical properties of fabrics, the breaking strength and strain were measured and surface reflectance was measured by color eye. The breaking strength and surface reflectance of fabrics by water soluble resin treatment showed difference by the different treatment concentration. The surface reflectance was increased by water soluble resin treatment. The breaking strength was lower in fabrics with resin treatment than fabrics with none treatment.

Five kinds of commercial ramie and hemp fabrics were treated with cellulase under different concentrations. Samples were mercerized before enzyme treatment to investigate the effect of mercerization on cellulase enzyme treatment. Physical characteristics(weight loss, tear strength retention, wrinkle recovery, drape stiffness, dyeability) of cellulase enzyme treated and untreated samples were measured and compared. X-ray diffractions were examined to verify if there were any changes in their crystallinity of enzyme treated fabrics. Weight loss, wrinkle recovery and degree of crystallinity increased as the concentration of cellulase enzyme increased. In the meanwhile, tear strength retention and drape stiffness and dyeability decreased. Enzyme activity was more effective on mercerized samples. Particularly, there was distinct tendency to increase weight loss and flexibility.

The repeatability of fabric drape was studied. Two methods for draping were used and the relation between node distributions was investigated using statistical analysis. With this, the relationship between node distribution and fabric mechanical properties was studied. The repeated measurements showed that there was no evidence that fabric has intrinsic node number and the mechanical properties influence on the number of nodes.
