摘要
羊毛表面鳞片外层的类脂结构使纤维具有显著的疏水性,阻碍了生物酶法防毡缩过程中酶分子向纤维内部的渗透.针对这一现象,使用甲醇/氢氧化钾和盐酸羟胺进行羊毛预处理,探究类脂层去除效果及其对羊毛结构与性能的影响;随后在盐酸羟胺去除羊毛类脂层的基础上,采用亚硫酸氢钠和Savinase 16XL蛋白酶对羊毛进行防毡缩整理.结果表明:三步法处理具有很好的羊毛防毡缩整理效果,织物毡缩率降至 5.44%,强力损失在可接受范围内.此外,织物润湿性、染色性、透气性和透湿性得到了显著改善,提高了羊毛纤维制品的产品附加值.
Abstract
The lipid structure of the outer layer of wool surface scales makes the fiber highly hydrophobic,which hinders enzyme penetration during the biological enzymatic anti-felting process.To address this issue,methanol/potassium hydroxide and hydroxylamine hydrochloride were used for wool pretreatment to investigate the removal effects of the lipid layer and its influence on wool structure and properties.Subsequently,after removing the wool's lipid layer with hydroxylamine hydrochloride,sodium bisulfite and Savinase 16XL protease were ap-plied to conduct anti-felting finishing for the wool.The results demonstrated that the three-step treatment had great wool anti-felting finishing effect,lowering the fabric's felting rate to 5.44%while keeping the strength loss within acceptable limits.Additionally,the wettability,dyeability,air permeability and moisture permeability of the fabric were significantly enhanced,thereby increasing the added value of wool fiber products.
