Enzymatic Treatment of Wool

Three proteases were applied to treatments of wool. The shrinkage, dyeing behavior, some physical and mechanical properties of treated wool were studied. Peroxymonosulfate(PMS) and lipase were used to pretreat wool before the treatment of it by protease. The results show that the shrink resistance of wool fabric is not obtained when it is treated only by the protease, but it is remarkably improved when the wool fabric is treated first by PMS or a lipase afterwards by protease. The rate of dyeing is increased when the wool is treated by protease or combination of oxidant/ lipase and protease. Whiteness, luster and softness of treated wool are improved, while the strength and elasticity are reduced.     

REDUCING HAIRFALLING AND PILLING STUDY IN RABBIT HAIR/WOOL WORSTED KNITWEAR——CHOOSING AND EVALUATING OF FINISHING AGENT

In the paper, the effects of reducing hairfalling and pilling were compared in rabbit hair/woolworsted knitwear by adding various finishing agents. Reducing rates of hairfalling and pilling wereof 6.7％—66.7％ and 9.3％—73.5％ respectively, while fabric handle changed from grade 1 to grade5 in 12 treating method groups. To evaluate the severity of hairfalling and pilling and the conditionof fabric handle of knitwear objectively, quantitatively and comprehensively, we advocated usingthe concept of "geueral evaluating value(GEV)". The results indicated that GEVs of acrylategroups were low, but GEVs of silicone resin groups were high, especially the group with finishingagent solution containing 7％ silicone resin No.3 in which reducing rates of pilling and hairfallingwere of 53％ (National standard: grade 4.5) and 62％, respectively, and washing stability was verygood, while knitwear's fabric handle almost did not change.
