Optimization mechanism of oxidation-enzymatic hydrolysis synergistic treatment for anti-pilling of wool fabrics
摘要
Abstract
Wool,a natural protein fiber,is pivotal in the textile and apparel industry owing to its superior thermal insulation,elasticity,and moisture absorption.Nevertheless,its scaly structure renders it prone to fuzzing and pilling,degrading appearance quality and wearing performance,while constraining its applications and market value.Traditional chlorination-resin finishing,though mitigating pilling,generates harmful by-products,contradicting green and sustainable development.Biological enzyme treatment,while eco-friendly,often exhibits limited efficacy.To overcome these challenges,this paper introduces an efficient and eco-friendly anti-pilling technology for wool fabrics,employing a synergistic treatment combining sodium persulfate oxidation with papain hydrolysis to preserve wool's excellent inherent properties. In this study,a synergistic approach combining sodium persulfate oxidation pretreatment and papain hydrolysis was employed to systematically investigate the influence of this combination on the properties of wool fabrics.The surface morphology and microstructure of the wool fabrics were characterized using SEM,FTIR,and XRD,among other techniques.Additionally,their anti-pilling characteristics,wear resistance,and dyeing performance were evaluated.The experiment thoroughly examined the effects of various process parameters—sodium persulfate concentration,pretreatment temperature and time,papain concentration,enzymatic hydrolysis temperature and time,and pH value—on the performance of wool fabrics.The optimal processing conditions were determined to be:sodium persulfate mass concentration at 71.4 g/L;pretreatment temperature at 50℃;pretreatment time at 75 min;papain mass concentration at 3 g/L;enzymatic hydrolysis temperature at 55℃;enzymatic hydrolysis duration for 50 min;and a pH level maintained at 7.Under these optimized conditions,the DFE of fibers was reduced to between 9.3%-9.7%,while fiber strength remained within a range of 1.19-1.24 cN/dtex.Furthermore,the fabric's pilling grade improved to grade 5.Research showed that sodium persulfate pretreatment loosened the scale structure of wool,providing more favorable reaction sites for papain hydrolysis.The synergistic effect of the two significantly enhanced the anti-pilling performance.Under optimized processing conditions,fabric top-breaking strength decreased by only 7.2%,moisture permeability increased by 3.5%,dyeing rate rose to 72.8%,air permeability remained unchanged,and,after 50 washes,pilling grade declined only half a grade(0.5).It can be seen that the treated wool fabric maintained good mechanical properties while also exhibiting improved wear-related properties such as wettability and moisture permeability. This paper effectively dismantles the wool flake layer structure via synergistic oxidation and enzymatic hydrolysis,substantially enhancing anti-pilling performance while preserving desirable wearing and dyeing properties.It provides innovative insights and methodologies for green processing and functional modification of wool fabrics,holding significant implications for advancing sustainable development in the textile industry.关键词
