Abstract

The invention relates to the technical field of textile fabrics, and discloses a preparation method of a superhydrophobic cotton and linen textile fabric. First, the cotton and linen fabric is steamed, SiO2 micron particles and ZnO micron particles are connected to the cotton and linen fabric through oxidized carboxymethyl chitosan, Ti(SO4)2 is hydrolyzed to form titanium dioxide nano-ions, and the titanium dioxide nano-ions are deposited on the surface of the cotton and linen fiber fabric and the SiO2 micron particles and ZnO micron particles to form a complex multi-layer microstructure and greatly improve the surface roughness of cotton and linen fibers in the cotton and linen fabric, so that the cotton and linen textile fabric has strong hydrophobic properties. The preparation method combines the gas permeability and the hydrophobicity of the cotton and linen textile fabric to allow the fabric to have waterproof and breathable properties.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a method for preparing superhydrophobic cotton and linen textile fabrics. Background technique [0002] Cotton and linen textile fabric is a fabric interwoven with cotton and linen, which has many advantages. For example, cotton and linen fabric has good air permeability, and after the body sweats, it can be released to the outside of the fabric in time with the air; , good comfort, suitable for next-to-body wear; antistatic, no pilling, no curling, no curling, cotton linen is sewn with pure cotton, no free charge, cotton fiber is not easy to deform, no pilling; natural environmental protection, From planting to hand-woven fabrics, no pesticides and chemical dyes are used, and the textiles do not contain chemical heavy metal ions such as formaldehyde and azo, and fully meet the requirements of "prohibited carcinogenic-azo dyes" stipulated in the European Union's textile b...
