The transfer of water vapor from the skin through clothing is an important factor in human comfort. This factor is resistance to the diffusion of water vapor through textiles. The resistance of woven fabrics depends not only on the kind of fiber, yarn number, thickness, cloth count, and its cloth structure, but also on the pore diameter and the open free area. The rate of water vapor transmission of woven fabrics increases in proportion to the pore diameter, the open free area, and the relative open free area(the ratio of the open free area to the thickness). Consequently this paper was shown the methods of the calculation of the pore diameter and the open free area from the characteristics of worsted fabrics made of ring spun yarns, and was evaluated the water vapor permeabilities of these fabrics by changes of the pore diameter and the open free area.

Cellulose powders were dissolved in the mixture of liquid ammonia and ammonium thiocyanate at room temperature. The cellulose solutions at the mesomorphic concentration were extruded into methanol bath by the dry-wet spinning condition. The tenacity and initial tensile modulus of the fiber increased with the anisotropic phase volume fraction of the solution but decreased with the specific layer birefringence of the mesomorphic solution. The spinning test results showed that the cellulose anisotropic phases were easily deformed by shear deformation that it indicates high potential for spinning this mesomorphic solution into a highperformance cellulosic fibers.

Photosensitive properties of poly(dimethyl-co-methylphenylsilylene) copolymer(PDMPS) was investigated by the residual film method of measuring the change of solubility of PDMPS before and after exposure to light. The samples coated on quartz plates were exposed to light under various conditions and steeped in the same solvent as used for coating, and then the yield of residual film(W/W0) was measured. The yield of residual film was affected by the molecular weight of PDMPS copolymer, types of photosensitizer, and their concentration. The most effective photosensitizer for PDMPS copolymer among those used here was rosebengal. And also, the photocrosslinking mechanism of PDMPS copolymer was studied by infrared an d UV absorption spectra. The stability of PDMPS spinning fiber by exposing to light was investigated by the change of the solubility of spun fiber after exposing to light was investigated by the change of the solubility of spun fiber after exposing to light.

IR spectroscopic and X-ray diffraction analysis were used for measuring crystallinity of cotton fibers slack-mercerized in aqueous ammonia/sodium hydroxide solution. The mercerization treatments led to a sharp decrease of crystallinity. Moisture uptake was used for estimating cellulose accessibility. The rate of dye adsorption of slack mercerized cottons increased compared with that of untreated cotton regardless of C.I. Reactive Blue 2 or C.I. Reactive Blue 19. The rate of dye adsorption of ammonia treated cottons increased compared with that of sodium hydroxide treated cottons.

Zr(IV) complex was used to bind antibiotics to cellulose fabric for imparting a high degree of antimicrobial property. Fabrics were successively treated with ammonium zirconyl carbonate solution and chlorampenicol or tetracycline hydrochloride solution by two-bath batch procedure. The reactivity of chlorampenciol with fabric containing zirconium complex was higher than that of tetracycline hydrochloride. Fabrics treated with chlorampenicol or tetracycline hydrochloride solution had a little zone of inhibition against the gram-negative bacterial, Klebsiella pneumoniae, after twenty launderings. These results show that the antimicrobial activity of the fabrics is due to controlled-release mechanism and fast to laundering.

Cellulose fabrics were treated successively with ammonium zirconyl carbonate solution and a solution of antibiotics such as streptomycin sulfate and gentamicin sulfate by two bath pad-cure/batch procedure and conventional two-both pad-cure procedure. The reactivity of streptomycin sulfate with fabric containing zirconium complex was higher than that of gentamicin sulfate. The fabrics reacted with streptomycin sulfate and gentamicin sulfate via zirconium complex as medium showed antimicrobial activity by a controlled-release mechanism. Antimicrobial activity imparted by treating with zirconium complex and antibiotics was initially extremely high. Durability to laundering of fabrics treated with zirconium complex and gentamicin sulfate was higher than that of fabrics treated with zirconium complex and streptomycin sulfate. Fabrics treated with zirconium complex and gentamicin sulfate retained adequate antimicrobial activity after twenty launderings.

This study was performed for the development of antimicrobial finished nonwoven fabrics. Viscose rayon nonwoven fabrics were treated with commercial organic silicon quaternary ammonium salt using batch technique according to various treatment conditions. Antimicrobial activity was evaluated by shake flask method, and the reactivity of organic silicon were evaluated by measuring the absorbance using UV-visible spectrophotometer. Mechanical properties such as tensile, bending, shear, compression, and surface properties related to hand were measured by KES-F system. The results obtained from this study were as follows; 1. Antimicrobial activity was significantly affected by the treatment concentration and temperature, Excellent antimicrobial activity was obtained at 0.3% o.w.f. concentration and optimum treatment temperature 4$0^{\circ}C$. 2. Silicon content increased with increased treatment concentration. It increased up to 30 minutes of treatment time and then decreased. The reactivity of specimen treated at the temperature higher than 4$0^{\circ}C$ rather decreased. To obtain excellent antimicrobial activity, silicon content taken up by specimen should be more than 100 ppm. 3. Tensile resilience, bending hysteresis, compressional energy and mean deviation of frictional coefficient of the treated specimen were increased, and tensile linearity, tensile energy, bending rigidity, shear rigidity, shear hysteresis, frictional coefficient and geometrical roughness were decreased in comparison with those of untreated specimen.

The purpose of this study is to evaluate the effect of mechanical properties on handle of fabrics for some of the Korea women's clothes. In this paper, the handle is regarded as a tactual evaluation judged from physical stimuli of fabric mechanical properties. The KES-F fabric testing systems were used to measure such mechanical properties, as tensile, bending, compression, shearing, surface characteristics and thickness & weight of fabrics for Korea women's clothes. 168 different kinds of commercial silk fabrics and polyester fabrics were used for this study. And also, the technique of stepwise-block-regression method was applied to investigate relation among these mechanical factors. Finally, we have obtained useful formulas for calculation the hand values of fabrics for Korean women's clothes. Furthermore, a comparison of formula was carried out between the fabrics for Korean women's clothes and Japanese women's thin dress fabrics.
