This study investigates the wash resistance of polyester fabrics functionalized with chitosan, a biopolymer known for its biocompatibility, non-toxicity, biodegradability and environmentally friendly properties. The interaction of chitosan with synthetic polymers, such as polyester, often requires surface treatment due to the weak natural affinity between the two materials. To improve the interaction and stability of chitosan on polyester, alkaline hydrolysis of the polyester fabric was used as a surface treatment method. The effectiveness of using cross-linking agents 1,2,3,4-butane tetracarboxylic acid (BTCA) and hydroxyethyl methacrylate (HEMA) in combination with ammonium persulphate (APS) to improve the stability of chitosan on polyester during washing was investigated. The wash resistance of polyester fabrics functionalized with chitosan was tested after 1, 5 and 10 washes with a standard ECE detergent. Staining tests were carried out to evaluate the retention of chitosan on the fabric. The results showed that polyester fabrics functionalized with chitosan without cross-linkers exhibited better wash resistance than the fabrics treated with crosslinkers.
本研究调查了用壳聚糖功能化的聚酯织物的耐洗性，壳聚糖是一种以其生物相容性、无毒、可生物降解和环境友好特性而闻名的生物聚合物。由于壳聚糖与合成聚合物（如聚酯）之间天然亲和力较弱，两者之间的相互作用通常需要进行表面处理。为了改善壳聚糖在聚酯上的相互作用和稳定性，采用聚酯织物的碱性水解作为表面处理方法。研究了使用交联剂1,2,3,4-丁烷四羧酸（BTCA）和甲基丙烯酸羟乙酯（HEMA）与过硫酸铵（APS）组合在洗涤过程中提高壳聚糖在聚酯上稳定性的有效性。用标准欧洲经济委员会（ECE）洗涤剂洗涤1次、5次和10次后，测试了用壳聚糖功能化的聚酯织物的耐洗性。进行染色试验以评估壳聚糖在织物上的保留情况。结果表明，未使用交联剂的用壳聚糖功能化的聚酯织物比使用交联剂处理的织物表现出更好的耐洗性。
