Abstract

The invention provides a preparation method of seaweed polyester master batch. According to the seaweed polyester master batch, the content of seaweed extract is 0.1-5%. The preparation method comprises a step of preparing a seaweed modifier. In the step of preparing the seaweed modifier, the seaweed extract, negative ion powder, calcium stearate, dodecyl dimethyl benzyl ammonium chloride and an ethanol-water solution are mixed, and stirred at a speed of 2000-2500rpm for 5-6h to obtain the seaweed modifier, wherein the volume ratio of ethanol in the ethanol-water solution is 6-8%. The preparation method further comprises the steps of preparing a loading agent, preparing master batch modified powder and preparing the seaweed polyester master batch. The dispersion degree and the uniformity degree of seaweed active ingredients in the prepared seaweed polyester master batch are remarkably improved, and no obvious agglomeration phenomenon occurs. A good inhibition effect is achieved. The seaweed polyester master batch has relatively 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 ...
