Abstract

The invention provides a preparation method of a hydrophilic and antistatic polyester fiber. The preparation method comprises the steps that a carbonic acid solution is adopted as a solvent of chitosan gel, and chitosan is applied to the surface of a polyester fiber; a stable graphene oxide-chitosan coating is formed on the surface of the polyester fiber through interaction between graphene oxide and the chitosan; after washing and drying are conducted, the hydrophilic and antistatic polyester fiber is obtained. According to the preparation method, carbonic acid is adopted as the solvent of the chitosan, a chitosan film can be directly formed to be deposited on the surface of the polyester fiber through heating, and a solvent removing step is not needed; the polyester fiber with the chitosan film and the graphene oxide have a high bonding effect; the prepared chitosan-graphene oxide-polyester fiber has the very good hydrophily and antistatic property. The green chemical preparation method is simple in preparation process, environmentally friendly and low in equipment requirement and has a wide application prospect.

Description

technical field [0001] The invention relates to a method for preparing hydrophilic and antistatic polyester fibers, belonging to the technical field of synthetic fibers. Background technique [0002] Polyester fiber is favored because of its excellent physical and mechanical properties and wearability. It is widely used in many fields and occupies a large market. In order to increase the added value of products, many companies are also developing and producing differentiated polyester fibers, such as flame-retardant polyester fibers, high moisture-absorbing and moisture-permeable polyester fibers, special-shaped polyester fibers, antistatic polyester fibers, antibacterial and deodorant polyester fibers, etc. Differentiated fibers. These differentiated polyester fibers have higher added value and a larger market. [0003] Chitosan is a natural macromolecular alkaline polysaccharide with good hydrophilicity, biocompatibility, antibacterial and biodegradability. It is widely...
