Problems solved by technology

Protective clothing needs to be durable and comfortable to wear. Nylon has good wear resistance and good hydrophilicity, which are characteristics that other fibers cannot replace. Therefore, fibers with these two characteristics and multifunctional properties have not been found in the market.

Abstract

The invention discloses a functional nylon 66 fiber and a preparation method thereof. The method performs blending granulation of nylon 66 resin slices, nanometer TiO2, and nanometer montmorillonite treated by an intercalator, and then performs melt blending spinning of the obtained master batch, nylon 66 slices, and nylon color master batch, and the functional nylon 66 fiber with multiple functions is produced by combination of specially-shaped spinneret plates with differentiation technology. The functional nylon 66 fiber is colored, has a specially-shaped cross section, has performance of ultraviolet resistance, bacterial resistance, static electricity resistance, flame retardation and infrared ray absorption, and is used for high-grade garment materials, knitted products, room textile, medical textile, and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of organic synthetic fibers and application of nanometer materials, in particular to a functional nylon 66 fiber and a preparation method thereof. The invention is applied to high-grade clothing fabrics, knitted products, indoor textiles and medical textiles, etc. Background technique [0002] Blending technology is mostly used in the production and manufacture of functional fibers, and the production of colored and special-shaped cross-section fibers is also a mature differential fiber manufacturing technology. The purpose of blending and spinning synthetic fiber resin raw material slices with a certain nanomaterial to achieve the purpose of fibers with certain special properties is also basically mature, and there are relatively many applications. For example, the invention patent with publication number CN102330188A introduces nano-SiO 2 Modified spun fiber preparation method, another exa...
