[0005] In the prior art, there are polyester materials with a single function and fibers made therefrom, or composite polyester materials with the above two functions and fibers made therefrom, which are obtained by adding anti- UV paste or flame retardant, thereby preparing polyester products with anti-ultraviolet function or flame-retardant function, such as Chinese patent CN101735578A, which discloses a flame-retardant and anti-ultraviolet polyester composite material and its preparation method. The material only modifies the polyester material in terms of flame retardancy and UV resistance, but does not modify its hygroscopic performance, and the flame retardant used in it contains halogen, which will bring toxic substances such as hydrogen halide while flame retardant. gas, may cause secondary poisoning incidents; and for example, Chinese patent CN201210526666.1 discloses a preparation method of moisture-absorbing flame-retardant polyester fiber, and its modification of polyester is limited to flame-retardant and moisture-absorbing aspects, No modification in UV
[0006] In summary, polyester and its fibers with composite functions of moisture absorption, UV resistance and flame retardancy have yet to be developed.

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...
