- Abstract
- Wool has excellent properties, such as heat retention, absorbency, and elasticity, but it has a disadvantage in washability because the fabric will felt and shrink greatly. Felting causes the interlocking of the fiber surface scales with one another. Therefore, the studies on wool finishing have been focused on shrink proofing. Precedent researches on wool shrink proofing are mostly on eco-friendly method using enzyme.
The purpose of this study is to examine the effect of L-cysteine, EDTA in papain treatment of wool fabrics. The specific contents of study are as follows. Depending on pH, temperature, treatment time, enzyme concentration and L-cysteine, EDTA concentration, weight loss, tensile strength, whiteness, SEM were examined. Each papain treatment conditons depending on L-cysteine, EDTA were optimized from these properties. Papain had very low activation without activators. The optimum conditions of papain treatment were pH 7.5, temperature 75℃, time 30minutes(L-cysteine), 180minutes(EDTA) and papain concentration 5%(o.w.f.). In the use of papain 5%(o.w.f.), the activators optimum concentration was L-cysteine 2%(o.w.f.), EDTA 7%(o.w.f.)
