Problems solved by technology

The convenience of conventional polyester production in my country has reached about 70% of the world's total output, but in the field of development and application of functional polyester, it is urgent for scientific researchers to make breakthroughs in the research of functional composite polyester, such as in polyester In the clothing field of polyester fiber materials, due to the poor hygroscopicity of polyester materials, it is easy to generate static electricity, pilling, easy to absorb dust, and the cloth surface is easy to get dirty, which limits its application in high-end clothing fabrics. Therefore, it is developed to have hygroscopicity. The modified polyester is of great significance

Abstract

The present invention relates to a self-adjusting and hygroscopic modified polyester synthesis method. The method comprises the steps of 1) mixing up sodium bentonite nanoparticles, halloysite nanotubes, ultra-fine diatomite, sodium alginate, p-hydroxy benzoic acid and the like with a certain proportion of ethylene glycol and propylene glycol, and grinding mixed materials in the sealed manner in a liquid ball mill to prepare a hygroscopic composite alcohol solution; 2) mixing up powdered steatile, sodium polyacrylate, polyethylene glycol and propylene glycol, and grinding mixed materials in the sealed manner in the ball mill to prepare a hygroscopic composite promoter; 3) mixing a certain proportion of the hygroscopic composite alcohol solution with ethylene glycol and terephthalic acid, subjecting mixed materials to reaction, adding a certain amount of the hygroscopic composite promoter during the medium stage of the reaction, and subjecting obtained materials to further polycondensation to prepare a self-adjusting and hygroscopic modified polyester. The prepared self-adjusting and hygroscopic modified polyester is an intelligent self-adjusting and hygroscopic structure material, and meets the adjustment control requirements of people on the ambient humidity.

Description

technical field [0001] The invention belongs to the technical field of polyester synthesis and modification, and in particular relates to a synthesis method of self-regulating and hygroscopic modified polyester. Background technique [0002] Polyester mainly refers to polyethylene terephthalate (PET for short) made by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG), which has good fiber-forming properties, mechanical properties, and wear resistance. Properties, creep resistance, electrical insulation properties, etc., it has a wide range of uses, and can be used to make plastics, films, fibers, etc. The convenience of conventional polyester production in my country has reached about 70% of the world's total output, but in the field of development and application of functional polyester, it is urgent for scientific researchers to make breakthroughs in the research of functional composite polyester, such as in polyester In the clothing field of polyester f...
