Abstract

The invention relates to a preparation method of an antibacterial sports knitted fabric. The preparation method comprises the following steps of changing spinneret holes on a spinneret plate into a trilobal shape from a circle in the process of preparing round sheath-core fiber from two kinds of PETs with different viscosities according to an FDY process, using cross air blow for cooling, and controlling the arrangement of the trilobal spinneret holes on the spinneret plate to meet certain conditions to prepare a sheath-core polyester fiber; after interweaving a yarn a (the polyester fiber with a circular cross section) and a yarn b ( the sheath-core type polyester fiber) into a grey fabric, sequentially performing composite finishing (firstly, putting the grey fabric into a deionized water solution containing a nano-silver antibacterial agent, then adding paraffin and polyester polyether linear block compound into the deionized water solution, and finally adding isopropanolamine) andperforming relaxation heat treatment to prepare the antibacterial sports knitted fabric; and the gram weight of the finally prepared antibacterial sports knitted fabric is 100 to 150 g / m2, the drip diffusion time is less than or equal to 2.0s, and the wicking height is 13.2 to 13.9cm.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a preparation method of antibacterial sports knitted fabrics. Background technique [0002] In recent years, with the promotion and widespread popularity of sports around the world, people not only increase the demand for sportswear, but also put forward higher requirements for the wearing comfort and health care functions of sportswear. Since exercise is prone to sweating and bacteria breeding, it affects the health of the body. Therefore, moisture absorption, quick drying and antibacterial properties have gradually become essential properties of sportswear. [0003] The antibacterial function can be achieved by adding antibacterial ingredients to the raw materials, or by performing antibacterial finishing on the fabric. For the moisture absorption and quick-drying performance, different raw material selections will have a great impact on the performance of the product. In...
