Polycarboxylics acids are used as crosslinking agents for cotton cellulose to produce durable finished press cotton fabric. It has been observed that the strength of the cotton fabric treated with polycarboxylic acids showed significant reduction as a result of the crosslinking process. The effect of acid-catalyzed depolymerization on the tear strength of cotton fabric is investigated by evaluating the cotton fabric treated by succinic acid, which does not crosslink cotton cellulose and form little ester on the cotton fabric. We find that the tear strength of cotton fabric treated with succinic acid decreases at elevated temperature due to acid-catalyzed depolymerization of cellulose. The magnitude of fabric strength reduction increases as the acid concentration increases. At a constant acid concentration, it increases as the curing temperature and time increases. It decreases as the pH of the acid solution increases. We also find that the dissociation constant of an acid also has a significant effect on the fabric strength reduction. The magnitude of fabric tear strength reduction increases as the acid dissociation constant decreases.

The purpose of this study is to investigate water and after vapor transport characteristics of underwear fabrics. Experimental materials were cotton woven fabric and cotton knitted fabric, nylon tricot (untreated and hydrophilic finished) and cotton/polyester/cotton triple layer. Cotton knitted fabric have three types of knit structure (interlock, rib, plain stitch) and knit with either 38's or 60's combed yarn. And cotton woven fabric have plain weave with 60's combed yarn. As experimental methods, vapor cup test, dynamic method, vertical wicking test and transplanar uptake test were used. The results are as follows. 1) In cotton specimens, the order of water vapor transpiration (wvt) was plain > rib > interlock in the same yarn diameter. The knit fabric of thinner yarn showed the better wvt among the same knit structure. 2) In cotton specimens, the order of water absorbency was interlock > rib > plain in the same yarn diameter. the knit fabric of thicker yarn showed the better absorbency among the same knit structure. 3) When knit fabric (60's plain) is compared with woven fabric 960's plain), knit fabric showed faster rate of wvt, more amount of uptake and slower rate of water uptake than woven fabric did. 4) When compared untreated nylon with hydrophilic finished nylon, hydrophilic finished nylon showed much more water absorbency than untreated nylon did, but showed same rate of wvt. 5) The water transport characteristics of triple layer underwear fabric showed that the thinner and the lighter one, the better wvt and absorbency did.

This study was conducted to suggest the best union fabric to combine with cellulose fiber for summer and in-between seasons. Four types of union fabric, viz. silk/flax, silk/cotton, rayon/flax and rayon/cotton, were used as sample fabrics after weaving them in a local textile factory. The air permeability, moisture regain, water absorption, water vapor permeability and thermal insulation of the samples were tested. The results are as follows. The rayon/flax union fabric is the most suitable for summer clothes due to its having the best comfort property of air and water vapor permeability, and moisture and water absorption. For in-between seasons, it is recommended to use the silk/cotton union fabric because of its good thermal insulation properties.

This study researches the mechanical and dyeing properties of wool fabric treated with papain. In this study, shrinkage, water contact angle, alkali solubility, and the dyeability of wool fabric treated with papain at the optimal activity condition were measured to confirm the effect of papain treatment. The shrinkage and water contact angle of wool fabric treated with papain decreased more than the untreated wool; however, the alkali solubility and the dyeability increased. L-cysteine was more active than EDTA as an activator of papain.

In this study, PET fabric was hydrolyzed with NaOH using the Tank m/c and Liquor-flow m/c to determine the alkali hydrolysis properties of PET fabrics. The results were as follows ： The weft density and tensile strength of PET fabrics hydrolyzed with Liquor-flow m/c were higher than those hydrolyzed with Tank m/c in case of less than 10％ of weight loss. However, above 10％ of weight loss, reverse phenomenon was showed. K/S value of hydrolyzed PET with Liquor-flow m/c was higher than that with Tank m/c above 10％ of weight loss. It was observed that the micropores of PET surface were collapsed due to physical force(abrasion and collision) during hydrolysis. Bending rigidity of hydrolyzed PET fabric was about 32％ and 40％ of bending rigidity of warp and weft direction of untreated fabric at 7％ of weight loss, respectively. Above 7％ of weight loss, decrease rate was decreased.

Shrink resist finishing of wool fabric was carried out with MONAMIN BTN shrink resist agent after chlorination with D.C.C.A.(dichloro isocyanuric acid). The purpose of this study is to investigate the effect of treating conditions, such as concentrations of D.C.C.A and MONAMIN BTN, pH of treating bath, dying times, curing times and temperatures, on shrink resist finishing. Mechanical properties of the treated fabric were measured by KES-FB system. The optimum chlorination of wool corresponds to 2∼3%(o.w.f.) of D.C.C.A. without rendering the damage on surface of wool fiber. Also it seems likely that the shirink resist finishing carried out at 2 ∼3%(o.w.f.) of MONAMIN BTN and pH 7∼8 of treating bath is effective in increasing a softness of hand.

In this study, the dyeing properties of double knit fabric composed of PET/PTT bi-component fiber and quick dry fiber were examined with disperse dyes. In addition, the shrinkage characteristics were investigated during the dyeing process. The K/S values and shrinkage rate of PET/PTT bi-component fiber were higher than those of PET/co-PET bi-component fiber and quick dry fiber. In the dye bath, dye migration of exhausted on PET/PTT bi-component fiber to quick dry fiber was found at high dyeing temperature. It was not found that there was a significant difference in K/S value on dyeing temperature between 115℃ and 130℃. But the slight color difference of two sides of a double knit fabric was found.

100％ viscose rayon fabric was treated with 1,2,3,4-butanetetracarboxylic acid (BTCA) by pad-dry-cure process in the presence of various catalysts. The dimensional stability, mechanical properties and hand values of fabric treated with BTCA were investigated. The ester-crosslinking reaction was influenced by the concentration of BTCA and type of catalyst. The fabric treated with BTCA was comparable or superior to that treated with conventional crosslinking agents such as dimethyloldihydroxyethyleneurea and 4,5-dihydroxy-1,3-dimethyl-2-imidazolidinone in respect of wrinkle recovery, shrinkproof property, retention of strength, and hand values. But in yellowing of fabric, the fabric treated with BTCA was inferior to that treated with conventional crosslinking agents. The fabric treated with BTCA/sodium formate was inferior to that treated with BTCA/sodium hypophosphite in respect of WRA, but had better strength retention and whiteness.

In this paper, silver slit yarns combined with cotton yarns were used to produce weft knits. The purpose of this study was to investigate the physical properties as well as the functional properties of weft knit with silver slit yarns. The six different weft knit fabrics were made from silver slit yarns varying knit structure and fabric density. One cotton weft knit was also knitted to compare the properties. Weft knits made from silver slit yarns were characterized by excellent antibacterial properties, electric magnetic shielding properties, UV-cut properties, anti-static properties, and air permeability. Although there were significant differences in the physical properties of different knit structure and the fabric density, weft knits with silver slit yarns were seen to have better end use properties and ideal for apparel than the cotton weft knits.
