Method for preparing mothproof silk fiber

The invention relates to the field of spinning materials and discloses a method for preparing mothproof silk fiber. The method includes the steps that firstly, gamma-cyclodextrin monoacetal is prepared; secondly, silver-loaded gamma-cyclodextrin monoacetal is prepared; thirdly, cellulose-fibroin dried gel particles are prepared; fourthly, silk fiber is grafted; fifthly, the silk fiber is subjected to dipping. The prepared silk fiber is long in mothproof time, the original smoothness of silk can be kept, tensile strength of silk can be improved, and the mothproof silk fiber is environmentally friendly and free of harm and does not influence human bodies. 本发明涉及纺织材料领域，公开了种防蛀蚕丝纤维的制备方法，包括：步骤1：γ-环糊精单醛的制备；步骤2：载银γ-环糊精单醛的制备；步骤3：纤维素-丝素干凝胶粒子的制备；步骤4：蚕丝纤维接枝；步骤5：蚕丝纤维浸渍整理。本发明制得的蚕丝纤维防蛀时效长，能够保持蚕丝原有的柔顺性，而且还能够提升蚕丝的抗拉伸强度，并且环保无害，对人体不会造成影响。
