角蛋白酶与蛋白酶-浴法羊毛防缩研究及机理分析
Study on shrink-proofing of wool and its mechanism analysis with keratinase and protease in one bath
摘要
Abstract
Wool was treated with keratinase from Bacillus subtilis and protease in one bath. Through felting rate, dyeing rate, K/S value, the modification effect of the two protease synergistic treatment on wool was investigated. The effect of the two protease synergistic treatment on the structure and properties of wool was investigated using FTIR-ATR, amino acid analysis and SEM. The results showed that the felting rate of the protease treated wool decreased, which could meet the machine washable demand. The dyeing rate was increased, however the weigh loss was increased, and the K/S value of dyed wool was decreased. FTIR-ATR indicated that one bath method could oxidize cystine of scale to alanine. The result of amino acid analysis showed that the content of cystine decreased after the protease treatment. SEM result showed that scale of wool was almost peeled, which indicated that keratinase and protease treatment in one bath process had evident modification effect on wool fabric.关键词
