Wool/Polyester 혼방 소모사의 방적공정중 섬유절단에 관한 조사와 25tex혼방사 방출시 polyester의 혼방율이 소모사의 물리적특성에 미치는 영향을 알아보았다. 방적공정중 섬유의 절단은 주로 carding 공정에서 일어났고, 더 나가서는 gilling 공정에서도 손상을 받았음을 알았다. polyester의 함량이 증가할수록 균제도, 꼬임수 변동, 인장강도와 절단선도 및 그들의 C.V.%등은 좋아졌고, 번수변동에는 별다른 영향을 주지 않았다. Some physical properties of wool/polyester blended worsted yarns were investigated. Fiber breakage was mainly occurred from the carding process, and later on, further in the consecutive gilling performance. In the 25 tex wool/polyester blended yarn, the content of polyester fiber contributed to the evenness, C.V.% of tpcm, breaking load, elongation at break and their C.V.%. But the C.V.% of yarn count was not affected significantly by the content of those two fibers.

Cotton fabrics were treated with glyoxal for a nonformaldehyde durable-press finish by a pad-dry-cure method. $MgCl_{2}/citric$ acid mixture or $Al_{2}(SO_{4})_{3}$ were used as a catalyst. The effects of additives such as sodium tetraborate decahydrate (STB), sodium peroxoborate tetrahydrate (SPB), and sodium chlorite (SC) were examined. The additives improved the whiteness and strength retention of the treated fabrics. SPB was superior to STB for the whiteness and strength retention. SC was better than either SPB or STB in the wrinkle recovery angles (WRA) and strength retention while the whiteness was similar to that of SPB or STB. SC was more effective for improving the whiteness and strength retention when it was used together with sodium phosphate monobasic.

The polyester/cotton 50/50 blend fabrics were treated with 1,2,3,4-butanetetracarboxylic acid (BTCA) by pad-dry-cure process to improve the smooth drying property. Sodium acetate (SA), non-phosphorus compound, was used as an alternative catalyst, because the conventional catalyst, sodium hypophosphite (SHP), has disadvantages such as high cost, eutrophication, and shade changes in certain dyed fabrics. The reaction condition and mechanical properties of fabrics treated with BTCA/SHP or BTCA/SA were investigated. The ester-crosslinking reaction was influenced by curing temperatures, the concentration of BTCA and catalyst, and pH values of the padding liquor. The fabrics treated with BTCA/SA were comparable to those treated with BTCA/SHP in respect of wrinkle recovery, DP rating, and whiteness index, and had better strength retention. The content of carboxyl group in treated fabrics became higher with the increase of the concentration of BTCA.

The hot alkaline solution not only reduces the weight of polyester. but also can be used for mercerization of cotton. The alkaline solution also cxhibits desizing and scouring action on cotton fabrics at high temperatures. In this study the effects of alkali concentration and reaction time on the weight loss of the polyester component. Mercerization of the cotton component and other properties of the polyester/cotton fabrics were investigated when they were treated at high temperatures. Furthermore the possibility of omitting the resizing and scouring processes was studied.

The evaluation for thermal protective performance of protective clothing against heat and flame was studied. In the case of protective clothing for workers, it has a good thermal stability with convective and radiant heat test. But the garments for firefighters were not the case. Although they had a good thermal stability to the convective heat test, they were not stable to the radiant heat test. This outcomes are a matter of grave concern. In spite that they failed in the radiant heat test, they still passed the standard by the current evaluation methods. Therefore it is necessary that the present evaluation methods of protective clothing should be complemented and revised.

When glyoxal was used as a crosslinking agent and aluminium ammonium sulfate as a catalyst for durable-press finishing, coreactants and additives to minimize the decrease of physical properties of durable-press finished cotton fabrics were studied. Also, optimum conditions such as coreactant/glyoxal mole ratio, the concentration of additives and the effects of one-bath and two-bath were investigated. Under the optimum concentration of DEG, the whiteness and strength retention of the fabrics treated with glyoxal/DEG/additive mixtures were increased while wrinkle recovery angles were decreased significantly. Under the optimum concentration of each additive, cotton fabrics were treated with various impregnation time in order to find the effect of two-bath method. The whiteness of cotton fabrics was increased by two-bath method, and wrinkle recovery angles were decreased either slightly or unchanged while the strength retention was not affected.
