摘要
蚕丝纤维因其优异的穿着舒适性,出色的力学性能、生物相容性、生物可降解性及其对人体无毒无炎症的特点,逐渐在多学科交叉融合应用方面表现出巨大的潜力,但同时也因其存在光致发黄、老化、细菌引起的变形甚至降解、不能机洗、难打理等缺陷,急需实现技术创新,开发具有更广阔应用场景的高性能/多功能蚕丝纤维.本文系统总结了高性能/多功能蚕丝纤维制备新技术,包括基因编辑法、添食法、物理改性法、化学改性法,并指出其所存在的问题和面临的挑战.在此基础上,进一步探讨了高性能/多功能蚕丝纤维的未来发展方向,以期为我国桑蚕产业的转型升级提供理论支撑.
Abstract
Silk fiber is increasingly recognized for its potential in a wide range of interdisciplinary applications due to its superior comfort,exceptional mechanical strength,biocompatibility,bio-degradability,and its harmless and non-irritating nature to human skin.However,it also faces several challenges,such as susceptibility to photo-yellowing,aging,microbial-induced distortion or deterioration,difficulties with machine washing,and demanding maintenance requirements.Consequently,there is a pressing demand for technological advancements to create high-perform-ance and multifunctional silk fibers suitable for more diverse uses.This review comprehensively examines the latest methods for producing advanced multifunctional silk fibers,encompassing genetic engineering,dietary interventions,physical and chemical modifications,while also high-lighting the associated issues and obstacles.Building on this analysis,the paper explores prospec-tive avenues for the evolution of high-performance and multifunctional silk fibers,aiming to offer theoretical insights that could facilitate the transformation and progress of China's sericulture in-dustry.
