The research deals with functionalization of a standard polyester fabric with biopolymer chitosan, whose premises are multifunctional and favour ecological effects. Due to the incompatibility of synthetic and natural polymers, the chitosan treatment was preceded by alkaline hydrolysis with sodium hydroxide with the addition of cationic and anionic surfactants as promoters. Compatibility of the chitosan with untreated and alkali-hydrolyzed fabrics was performed by analysis of mechanical and physico-chemical properties. The number of characterisation procedures performed required the use of hierarchical cluster analysis (HCA) to identify homogeneous groups or clusters in which similarities and differences between samples are visible. Almost all applied methods and evaluation parameters have shown that alkaline hydrolysis of polyester fabric has the best potential for functionalization with chitosan. Therefore, the addition of surfactants as promoters during alkaline hydrolysis is not necessary in the pretreatment process phase.
该研究涉及用生物聚合物壳聚糖对标准聚酯织物进行功能化处理，其前提是具有多功能性并有利于生态效应。由于合成聚合物和天然聚合物不相容，在壳聚糖处理之前先用氢氧化钠进行碱性水解，并添加阳离子和阴离子表面活性剂作为促进剂。通过分析机械和物理化学性质来评估壳聚糖与未处理和碱水解织物的相容性。所执行的表征程序数量需要使用层次聚类分析（HCA）来识别样本之间具有相似性和差异的同质组或簇。几乎所有应用的方法和评估参数都表明，聚酯织物的碱性水解具有用壳聚糖进行功能化的最佳潜力。因此，在预处理过程阶段，在碱性水解期间添加表面活性剂作为促进剂是不必要的。
