Problems solved by technology

[0004] Traditional cotton fabrics have relatively single functionality, and are prone to breed bacteria and mildew during long-term use, which reduces the comfort of cotton fabrics. At the same time, current cotton fabrics lack self-cleaning functions, and are easy to get dirty and difficult to clean

Embodiment 1

[0028] A kind of preparation method with antibacterial and self-cleaning cotton fabric, comprises the following steps:

[0029] S1. The preparation of the antibacterial layer, at first coating the upper and lower sides of the bamboo fiber cloth with nano-silver sol, and then drying the bamboo fiber cloth coated with nano-silver sol, so that the nano-silver sol can be combined with the bamboo fiber cloth. Fiber fabrics are combined to obtain an antibacterial layer, and then the antibacterial layer is thermally bonded to the cotton fabric;

[0030] S2. The preparation of the self-cleaning layer, which changes the surface structure of the cotton fabric through bionics to form a microemulsion protruding surface "lotus leaf structure", thereby endowing the textile with an excellent water and oil repellent effect; at the same time, on the surface of the cotton fabric Adhering to photocatalysts with photocatalytic ability, such as titanium dioxide and zinc oxide, can release electron...

[0042] A kind of preparation method with antibacterial and self-cleaning cotton fabric, comprises the following steps:

[0043] S1. The preparation of the antibacterial layer, at first coating the upper and lower sides of the bamboo fiber cloth with nano-silver sol, and then drying the bamboo fiber cloth coated with nano-silver sol, so that the nano-silver sol can be combined with the bamboo fiber cloth. Fiber fabrics are combined to obtain an antibacterial layer, and then the antibacterial layer is thermally bonded to the cotton fabric;

[0044] S2. The preparation of the self-cleaning layer, which changes the surface structure of the cotton fabric through bionics to form a microemulsion protruding surface "lotus leaf structure", thereby endowing the textile with an excellent water and oil repellent effect; at the same time, on the surface of the cotton fabric Adhering to photocatalysts with photocatalytic ability, such as titanium dioxide and zinc oxide, can release electron...

Abstract

The invention discloses a preparation method of an antibacterial and self-cleaning cotton fabric. The preparation method comprises the following steps that an antibacterial layer is prepared, and firstly nano-silver sol is coated on the upper surface and the lower surface of bamboo fiber cloth; then the bamboo fiber cloth coated with the nano-silver sol is dried, so that the nano-silver sol can be combined with the bamboo fiber cloth, and the antibacterial layer is prepared; then, the antibacterial layer and the cotton fabric are subjected to heat bonding connection; a self-cleaning layer is prepared, and the surface structure of the cotton fabric is changed through bionics, so that a micro-emulsion lotus leaf structure protruding out of the surface is formed; and meanwhile, titanium dioxide, zinc oxide and other photocatalysts with photocatalytic capacity are attached to the surface of the cotton fabric, electrons can be released under the irradiation of ultraviolet rays and react with oxygen in air, and oxygen free radicals with strong oxidizing capacity are generated. The surface structure of the cloth can be changed through bionics, the self-cleaning capacity is enhanced through photocatalysis, and manufacturing is simple.

Description

technical field [0001] The application relates to the technical field of cotton fabrics, in particular to a method for preparing cotton fabrics with antibacterial and self-cleaning properties. Background technique [0002] Cotton fabric is a cloth made of cotton yarn. It is a general term for all kinds of cotton textiles. It is mostly used to make fashion, casual wear, underwear and shirts. Its advantages are easy to keep warm, soft and close to the body, good hygroscopicity and air permeability. The disadvantage is that it is easy to shrink and wrinkle, and the appearance is not very crisp and beautiful. It must be ironed frequently when wearing it. [0003] The production and manufacture of cotton cloth includes three processes of spinning, weaving and dyeing and finishing. Spinning and weaving are the processes of processing textile fibers into yarns and fabrics by mechanical means, while dyeing and finishing is the process of processing textile fibers into yarns and fabr...
