Problems solved by technology

However, because the molecular weight of the silane coupling agent is not large enough and the organic chain length is short, it may volatilize before the spinning temperature is reached, affecting the modification effect and the spinning process.

Abstract

The invention provides a manufacture method for a surface-modified flatting agent for a polyamide chemical fiber. The manufacture method comprises the following steps of: with anatase titanium dioxide with the size distribution of 200-500 nm as a raw material, depositing a layer of amorphous oxide with the thickness of 1-100 nm on the surface of the anatase titanium dioxide by utilizing a precipitation method, then processing the surface of the anatase titanium dioxide by utilizing a compound coupling agent containing amino and epoxy group so as to carry out organic modification, and finally obtaining modified titanium dioxide with excellent dispersity and compatibility in a caprolactam-water system, namely the modified flatting agent provided by the invention.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a method for manufacturing a surface-modified matting agent for nylon chemical fibers. Background technique [0002] Polyamide, also known as nylon, is the main variety of synthetic fibers and the first fiber to be developed and produced. After 1972, polyester fiber replaced its position and became the largest variety of synthetic fiber production. However, due to the advantages of high strength, good resilience, wear resistance and fatigue resistance, polyamide fibers are still widely used in three major fields such as clothing, industry and decorative carpets. In recent years, polyamide products are often seen even in high-end textile industries such as fancy yarn, high-speed warp knitting, and lace, which is mainly due to the development of full-dull polyamide products. [0003] The application of powder nanomaterials in the chemical fiber industry has a long histor...
