Embodiment 1

[0023] A color spinning loaded photocatalyst yarn is made by blending 15-35 parts by weight of white fibers, 20-40 parts by weight of light gray fibers and 20-45 parts by weight of blue fibers;

[0024] Using cotton fiber as raw material;

[0025] Photocatalyst dispersion liquid: the average particle size of nano titanium dioxide is 180nm, the molecular weight of degraded chitosan is 3000, the mass ratio of the two is 5:1, and water is used as solvent to prepare dispersion liquid with titanium dioxide concentration of 2 g / L and 3 g / L ;

[0026] Fiber dyeing: Divide the pretreated cotton fiber into three parts at a ratio of 25:30:45, add them to white, light gray, and blue dye solutions respectively, dye at 55°C for 30 minutes, then cool to room temperature and adjust with acetic acid. After the pH is 6.8, it is washed with water, then oiled, dehydrated and dried to obtain three kinds of fibers with different color shades, namely white dyed fiber, light gray dyed fiber and blu...

Abstract

The invention belongs to the technical field of textiles, and particularly relates to a yarn containing a photocatalyst. The raw materials of the yarn comprise white fibers and colored fibers, whereinthe white fibers are loaded with the photocatalyst, and the colored fibers are not loaded with the photocatalyst. The yarn containing the photocatalyst has the advantages that the yarn is prepared through selective loading with the photocatalyst and a blending process, which not only can reduce the cost and ensure the stability of the yarn colors, but also can impart various functions such as deodorization, bacterium resistance and mould resistance to the yarn, and an adopted photocatalyst material is environmentally friendly and safe, and can be widely used in the field of life.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a yarn containing a photocatalyst and a preparation method thereof. Background technique [0002] The dyeing process of the traditional textile industry is divided into yarn dyeing and fabric dyeing, while the color spinning process is to complete the dyeing of fibers before spinning and weaving. Color spinning not only solves the problem of cylinder difference in grey fabric dyeing, but also can produce complementary properties through fiber blending, giving fabrics unlimited development space. Since the fiber is a porous material, a multi-layer body with numerous voids will be formed after superimposed knitting, so the fabric is easier to absorb bacteria. [0003] At present, there are two main processing methods for antibacterial fabrics: one is to directly use antibacterial fibers to make various fabrics, and the obtained fabrics have long-lasting antibacterial ...
