摘要/Abstract

摘要： 研究了柞丝绸用脂肪酶接枝脂肪醇提高其拒水性能。研究结果表明：柞丝绸接枝正十八醇的接枝率可以达到19.8%；接枝的脂肪醇级别越高，柞丝绸水接触角越大，沾水级别越高。水接触角从对照的55.8o提高到128.3o；沾水等级从0级提高到3级；接枝改性柞丝绸的透气性略有升高。洗涤试验表明：酯化接枝改性的柞丝绸具有良好的耐洗涤性能。因此，柞丝绸用脂肪酶接枝高级脂肪醇提高其拒水性能是一绿色、有效的整理方法。

Abstract: In this paper, the tussah silk fabric was modified with fatty alcohol by lipid enzyme. The results showed that the highest grafting rate could reach to 19.8%, and the longer the hydrocarbon chain of fatty alcohol were, the greater of the water contact angles on modified tussah silk fabric surface were. The water contact angle could change from 55.8o to 128.3o, and the spray grade increased from 0 to 3. The air permeability of modified tussah silk fabric increased a little. The washing test showed that the esterified tussah silk fabric has good scourability. The hydrophobic property of esterified tussah silk only decreased a little after modified tussah silk fabric was washed 20 times. Therefore, the grafting method to endue the tussah silk fabric hydrophobic property was green and effective.

Key words: tussah silk fabric, gydrophobic, lipase, contact angle, fatty alcohol
