Abstract

The invention provides a method for preparing seaweed polyester masterbatch, wherein the seaweed polyester masterbatch has a seaweed extract content of 0.1-5%. The preparation method comprises the preparation steps of the seaweed modifier; the preparation step of the seaweed modifier: the seaweed extract, negative ion powder, calcium stearate, dodecyl dimethyl benzyl ammonium chloride and ethanol The aqueous solution is mixed, the volume ratio of ethanol in the ethanol-water solution is 6-8%, and the seaweed modifier is obtained by stirring at a speed of 2000-2500rpm for 5-6h. The preparation method also includes the steps of preparation of loading agent, preparation of masterbatch modified powder and preparation of seaweed polyester masterbatch. The degree of dispersion and uniformity of the seaweed active ingredients in the prepared seaweed polyester masterbatch is significantly improved, and there is no obvious agglomeration phenomenon; it has a good inhibitory effect. It has strong negative ion and far infrared effects.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, and in particular relates to a seaweed polyester masterbatch and a preparation process thereof. Background technique [0002] Polyester is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, referred to as PET fiber, which belongs to polymer compounds. Invented in 1941, it is currently the largest variety of synthetic fibers. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery ability. It is strong and durable, anti-wrinkle and non-ironing, and non-sticky. However, it has poor hydrophilicity and air permeability, and people feel poor when wearing it. [0003] With the continuous improvement of people's living standards, people have higher and higher requirements for clothing fabrics, not only requiring the improvement of ...
