中文摘要：针对传统碱剂砂洗中蚕丝强力下降明显及褪色严重等问题,利用固载化交联蛋白酶聚集体(ICLPAs)对蚕丝进行砂洗整理。通过对ICLPAs制备工艺条件进行优化,探讨了ICLPAs的稳定性和重复使用性。通过对 KES织物风格、毛效、透气性、透湿性、热阻、湿阻、悬垂性、强力的测试,分析了ICLPAs对蚕丝织物的砂洗效果。结果表明:与游离蛋白酶相比,ICLPAs的热稳定性、pH 值稳定性和重复使用性均得到提高;利用 ICLPAs 对蚕丝织物进行砂洗处理,部分丝素发生水解帚化,织物表面产生微绒,织物的柔软性、抗皱性、吸湿透湿性、透气性提高,断裂强力下降;ICLPAs 处理后蚕丝织物的弯曲刚度为0. 0031cN cm,悬垂系数为 1.97%,折皱回复角为 225°,毛效(30 min)为11.3cm,透气性为372.1L/(m2· s),透湿性为2303g/(m2 ·d)。

外文摘要：Aiming at the obvious strength decrease and serious fading in silk sanding with conventional alkali agent, the immobilized cross-linked protease aggregates (ICLPAs) were used for sanding of silk fabrics. The preparation conditions of ICLPAs were optimized, and the stability and reusability of ICLPAs were investigated. The properties of ICLPAs-treated fabric were studied by testing KES fabric style, capillary effect, air permeability,moisture penetrability, thermal resistance, wet resistance, drapability and strength. The results show that the thermal stability, pH stability and reusablility of ICLPAs are all improved compared to free protease. The silk fibroin of the ICLPAs-treated fabric is hydrolyzed. The microvelvet is produced on the fabric surface. The softness, wrinkle resistance, moisture absorption, moisture permeability, air permeability increase and the breaking strength decrease. The bending rigidity of the ICLPAs-treated fabric is 0. 003 1 cN cm and drape coefficient is 1. 97%. The crease recovery angle is 225°.The capillary effect (30 min) of the treated fabric is 11. 3 cm. The air permeability is 372.1L/(m2 ·s)andthemoisturepenetrabilityis2303g/(m2 ·d).
