Problems solved by technology

[0003] Nowadays, in order to meet the needs of fabrics, we have begun to develop new fabrics with various properties, such as antibacterial fabrics with excellent antibacterial properties. Conventional antibacterial fabrics mostly use the structure of base fabric-antibacterial middle layer-outer fabric Composite, while the antibacterial middle layer is mostly prepared in the form of antibacterial coating, which not only increases the production cost, but also reduces the breathability of the fabric, making it uncomfortable to use

Abstract

The invention discloses a bio-based high-breathability antibacterial fabric and a preparation method thereof. The antibacterial fabric comprises a base cloth and an outer-layer cloth, and the base cloth and the outer-layer cloth are bonded through a modified hot melt adhesive; the modified hot melt adhesive comprises a hot melt adhesive, modified silicon dioxide, an additive A and an additive B; the modified silicon dioxide is mainly prepared from hexadecyltrimethylammonium bromide, tetraethoxysilane, mercaptopropyltrimethoxysilane, methylbenzene and hydrogen peroxide; the additive A is mainlyprepared from silver nitrate, glucose and sodium chloride; and the additive B is mainly prepared from chitosan, 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride, N-hydroxysuccinimide and lysine. According to the bio-based high-breathability antibacterial fabric and the preparation method thereof, the process design is reasonable, the component proportion is proper, and the prepared antibacterial fabric has excellent antibacterial performance and breathability and has high practicability.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a bio-based highly breathable antibacterial fabric and a preparation method thereof. Background technique [0002] Composite fabric is a new type of material formed by bonding one or more layers of textile materials, non-woven materials and other functional materials; it is suitable for sofas, clothing and other textiles, and is one of the indispensable fabrics for people's home life. . [0003] Nowadays, in order to meet the needs of fabrics, we have begun to develop new fabrics with various properties, such as antibacterial fabrics with excellent antibacterial properties. Conventional antibacterial fabrics mostly use the structure of base fabric-antibacterial middle layer-outer fabric Composite, while the antibacterial intermediate layer is mostly prepared in the form of antibacterial coating, which not only increases the production cost, but also reduces the breathability of ...
