Antibacterial chitosan fabric and preparation method and product thereof

Abstract

The invention discloses an antibacterial chitosan fabric and a preparation method and product thereof. The antibacterial chitosan fabric is prepared by knitting or weaving skin-core composite filaments; the skin-core composite filaments comprise core layers and skin layers; the skin layers coat the outer surfaces of the core layers, and the cross-sectional profiles of the skin layers are circular;the cross-sectional area ratios of the core layers and the skin layers are 1 : (0.7-0.8); the core layers are prepared from the following raw materials in parts by weight: 90-95 parts of polyethyleneterephthalate and 5-10 parts of polypentanediamine adipate; the skin layers are prepared from the following raw materials in parts by weight: 4-8 parts of polyethylene terephthalate, 86-92 parts of polypentanediamine adipate, 1.6-2.0 parts of nano graphene sheets, 6-9 parts of chitosan, 3-5 parts of diatomite, 3-4 parts of fumed silica and 4-5 parts of a dispersant. The antibacterial chitosan fabric has the advantages of high antibacterial rate, good antibacterial effect, good wear resistance, high tensile strength and good mechanical property.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a chitosan antibacterial fabric, a preparation method and a product thereof. Background technique [0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. Among them, functional fabrics refer to fabrics with certain special properties and uses, such as waterproof, windproof, breathable, moisture-permeable, warm, oil-proof, easy to decontaminate, anti-bacterial and deodorizing, anti-ultraviolet, anti-static, anti-radiation, Anti-flame retardant, high temperature resistance, acid and alkali resistance and other functions. The functional fabrics on the market are mainly clothing fabrics, which are mostly used in outdoor sportswear and high-end casual wear. Among the new functional textile materials, pol...

AI Technical Summary

Problems solved by technology

[0006] 1. The antibacterial and antibacterial effect is poor. When it is used as clothing fabric to sweat or have other pollution, it is easy to breed bacteria, affect health, and even stink, and the user experience is poor;

[0007] 2. Antibacterial agents such as nano-silver are usually added, the antibacterial effect is poor, the antibacterial effect is not durable, and the mechanical properties of the fabric are affected;

[0008] 3. Poor mechanical properties and poor wear resistance. When used as fabrics for outdoor (sports) products and / or clothing, it is easy to be scratched and has a short service life.
