Research Progress and Development Trend of Hydrophilic Modification of Polyester Fiber
Polyester fiber has good mechanical properties and chemical stability,but its hydrophilicity is poor due to the lack of polar groups,which limits its application in some fields.This paper introduced the principle of hydrophilic modifi-cation of polyester fiber,reviewed a variety of hydrophilic modification methods used in polymer synthesis stage,spinning stage,dyeing stage and finishing stage of polyester fiber processing.The advantages and disadvantages of each modification method were analyzed and summarized,which provided a reference for the selection of hydrophilic modification methods of polyester fiber and provided a new possibility for its application in textile and environmental protection field.The research shows that the future study should focus on the optimization of existing modification methods,and actively exploring and developing more environmentally and friendly modification methods to improve the stability of modified fibers and achieve multi-functional modification to meet the evolving application needs.
