摘要/Abstract

摘要： 研究了丝绸部分乙酰化的抗皱整理，同时对乙酰化丝绸进行了红外光谱、X-射线衍射、DSC以及服用性能测试分析。研究结果显示，乙酰化丝绸折皱弹性大幅提高，缓弹和急弹折皱回复角分别由218.5°和168.5°提升到270.5°和210.5°，表明只降低丝绸形成氢键能力的非交联型整理剂也能大幅度提高丝绸的折皱弹性；红外光谱分析表明乙酰化丝绸的β折叠结构增加，氨基被部分乙酰化；X-射线衍射分析表明乙酰化丝绸的结晶度增加；DSC分析表明乙酰化丝绸的分解温度提高，热稳定性增加；同时乙酰化丝绸的回潮率、白度、断裂强力等基本无变化，其刚柔度有所增加，挺括性提高。

Abstract: In this paper, silk was acetylated to increase its wrinkles elasticity. The structure of acetylated silk was analyzed by infrared spectrum, X-ray diffraction and DSC. And the wearability was measured too. The results showed that acetylating silk could increase the wrinkles elasticity greatly. The crease recovery angle of slow and urgent respectively grew from 218°and 168 °to 210 °and 270 °. This suggested decreasing the capacity to form hydrogen bonds could increase the wrinkles elasticity of silk greatly. Infrared spectral analysis showed that the Beta-Sheet structure of the acetylated silk increased and part of amino decreased. X-ray diffraction analysis showed that the degree of crystallization of the acetylated silk increased. DSC analysis showed that the acetylated silk’s decomposition temperature and thermal stability increased. At the same time, the moisture regain, whiteness and breaking strength of acetylated silk kept well. Flexual stiffness of acetylated silk was improved a little.

Key words: acetylation, silk, wrinkle elasticity, degree of crystallization, wearability
