TDEA、TDEB 提高丝绸湿弹性机理的研究

STUDY ON MECHANISM OF INCREASE OF WET-CREASE RECOVERY OF SILK FABRICS BY TDEA OR TDEB

采用自制的整理剂 TDEA 和 TDEB 对丝绸进行整理。通过耐洗率度,DSC、红外光谱和氨基酸分析测试证明 TDEA、TDEB 与丝素发生了化学反应;并通过丝素的溶胀试验、溶解度试验进一步证明TDEA、TDEB 与丝素发生了共价交联反应,从而可以认为 TDEA、TDEB 与丝素间发生共价交联作用是使丝绸湿弹性获得显著提高的主要原因。

Silk fabrics is finished with TDEA or TDEB.By means of washing fastness,DSC,IR spectrumand amino-acid analytical tests,TDEA or TDEB is confirmed to react with fibroin.With help of testsof fibroin swelling and solubility in some sovents,crosslinking reactions between TDEA or TDEB andfibroin are further proved,which is obviously responsible to the increase of wet-crease recovery of silkfabrics finished by TDEA or TDEB.
