棉织物的丝胶涂层整理及其性能

Study on sericin coated finishing of cotton fabric and its properties

为开发高品质、功能性的棉制品,采用带负电荷的丝胶蛋白与带正电荷的壳聚糖衍生物在水溶液中发生反应,生成具有一定胶黏作用的新型微颗粒,再通过聚丙烯酸类低温交链剂进一步将丝胶固着在棉织物上。对整理前后棉织物的服用性能、表面形态等进行测试,结果表明:丝胶均匀涂覆在棉织物上,且耐洗性良好,洗涤5次后的溶失率约为0.21%,丝胶整理后棉织物的吸放湿性、保温性、透湿性和抗菌性均有提高,透气性基本不变,是一种新型高档棉制品。

In order to develop high quality and functional cotton product,sericin with negative charge and chitosan derivative with positively charged were reacted to form a new micro particles with viscose effect in aqueous solution.Then sericin was further fixed on cotton fabric by polyacrylic acid crosslinking agent reacted at low temperature.The wearability,surface morphology and structure of cotton fabrics were tested before and after sericin coating.The results showed that sericin was uniformly coated on the surface of cotton fabric.The coating had good washing durability.The dissolve loss rate of sericin coated on fabric is about 0.21% after five washing cycles.The moisture absorption,thermal insulation,moisture permeability and biocidal property of sericin coated cotton fabric increased,but the air permeability showed no significant change.The sericin coated cotton fabric was a new kind of top grade cotton products.
