Abstract

The present invention discloses a polyester having moisture absorption, fire retardation and ultraviolet resistance composite function. According to the present invention, a fire retardation agent, inorganic nanometer anti-ultraviolet powder, a moisture absorption modification monomer and the like are added to the polymerization raw material, wherein the fire retardation agent and the moisture absorption modification monomer have the synergy effect so as to improve the moisture absorption property of the polyester, such that the chemical structure of the polyester is modified so as to make the polyester concurrently have functions of strong moisture absorption, strong fire retardation and strong ultraviolet resistance.

Description

technical field [0001] The invention relates to the fields of polymer materials and textile fiber materials, in particular to a polyester with composite functions of moisture absorption, flame retardancy and ultraviolet resistance. Background technique [0002] Polyester fiber, namely polyester, has good strength, drapability, excellent wrinkle resistance and is practical and durable, so it is widely used in clothing textiles. However, garments made of polyester fibers still have many deficiencies in terms of heat and humidity comfort, health protection and flammability when worn. As well as Guangdong Shunde Jinfang Group, etc., all use special-shaped spinnerets to form various types of fine grooves on the surface of polyester fibers to achieve the purpose of dehumidification and quick drying, and to prepare polyester products with comfortable functions. The surface morphology of the fiber has been modified, but the molecular structure of the polyester fiber has not been im...
