The essence of the treatment is to add a hydrophilic compound on the surface of the fabric or fabric, which can increase the moisture absorption and water absorption of the fiber while maintaining the original properties of the fiber, so as to improve the hydrophilic properties of the fiber surface. < /p >

This is a sort of finishing method, which is a homogeneous and firm hydrophilic finishing agent on the surface of the fiber to form hydrophilic. It is the main processing method for hydrophilic finishing of synthetic fabrics in recent years. < /p >
< p > in this method, the finishing agent which contains both hydrophilic groups and functional groups of cross-linking reaction is generally selected. The hydrophilic segments provide hydrophilic properties, while the cross-linking reaction functional groups form thin films on the surface of the fibers, thereby improving the durability of the finishing agents. < /p >
< p > in addition, it is also possible to choose a water-soluble polymer containing a hydrophilic group and a suitable crosslinking agent to form a system to control the reaction degree between the crosslinking agent and the water-soluble polymer, so that a part of the hydrophilic group of the water-soluble polymer is retained on the surface of the fiber, so that the hydrophilicity of the fiber is improved. < /p >
< p > commonly used water-soluble polymers are polyacrylic acid, polyvinyl alcohol, water-soluble cellulose, soluble starch and so on. Crosslinking agents are substances that can react with active groups such as amino and hydroxyl groups, such as 2D resin. This method is used not only for conventional hydrophilic finishing, but also for finishing superabsorbent products. < /p >
< p > 2. surface grafting polymerization. Surface grafting copolymerization is used to graft hydrophilic monomers onto the surface of synthetic fibers in order to improve the hydrophilicity of synthetic fibers. < /p >
< p > graft polymerization is the use of initiator or high-energy radiation (electron beam, ultraviolet) irradiation, or plasma treatment, so that the surface of the fiber produces free radicals, and then the hydrophilic monomer on the free radical graft polymerization, thereby forming a durable water absorption and antistatic properties of the new surface layer. < /p >
