Abstract

The invention discloses a preparation method of core-spun yarns, and belongs to the technical field of textile preparation. The core-spun yarns disclosed by the invention help neutralize the characteristics of natural fibers, so that the strength and elasticity of cotton fibers are improved. According to the invention, the cotton yarns prepared from the natural plant fibers are immersed in a reinforcing adhesive with titanium dioxide; when in liquid media, especially in polar media, titanium dioxide particles can attract opposite charge to form a diffused double electrode layer since their surface is charged; the effective diameter of the particles is increased, so that fine particles are firmly attracted in pores of the cotton yarns due to an electrostatic effect when passing through thecotton yarns; activated carbon used herein is prepared by firing bamboo chips at high temperature without oxygen; as bamboo is acidic, the prepared activated carbon is also acidic; therefore, the antibacterial effect can be achieved, the moisture absorption characteristic of the cotton fibers can be improved, clothes, cotton quilt and the like prepared with the cotton fibers have sweat absorptioncapacity, are more comfortable to wear, are widely applicable.

Description

technical field [0001] The invention discloses a method for preparing a core-spun yarn, which belongs to the technical field of textile preparation. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The original core-spun yarn is short fiber and short-fiber core-spun yarn developed with cotton fiber as the skin and polyester spun yarn as the core. New bead thread with polyester coated polyester cored thread. [0003] Core-spun yarn is generally a yarn made of synthetic fiber filaments with good strength and elasticity as the core yarn, and short fibers such as cotton, wool, and viscose fibers are twisted and spun together. The core-spun yarn combines the excellent properties of the filament core yarn and the outer staple fiber. The more common core-spun yarn is polyester-cotton core-spun yarn, which uses polyester filament as the core yarn and is covered with cotton fibers. Th...
