Problems solved by technology

[0003] However, although the cotton fabric made of cotton fiber is comfortable to wear, it has a large specific surface area and strong moisture absorption capacity, which makes cotton products easy to attach microorganisms, and creates conditions for their reproduction and propagation, resulting in strong fiber damage and breeding. Bacteria, and even cause the spread of disease, affecting human health
[0004] In recent years, with the rapid development of nanotechnology, some nano-inorganic antibacterial agents have been applied in the field of textile and clothing because of their remarkable broad-spectrum antibacterial properties. At present, the antibacterial finishing of webbing mainly adopts post-finishing method. However, the post-finishing method often appears that the antibacterial effect of the webbing after finishing is not durable enough and the washability is poor due to the weak combination of nano-silver

Abstract

The invention discloses an in situ-based production method of an antibacterial ribbon. The method comprises the following steps: allowing cotton fibers to enter sodium periodate in order to obtain oxidized cotton fibers, impregnating the oxidized cotton fibers in polyethyleneimine to obtain polyethyleneimine grafted cotton fibers, allowing the polyethyleneimine grafted cotton fibers to enter silver nitrate in order to prepare antibacterial cotton fibers, and carrying out normal ribbon interlacing to obtain the antibacterial ribbon. The antibacterial ribbon produced through the method has very good soaping resistance and highly-efficient and lasting antibacterial property, still keeps the sterilization rate at 95-100% after 30 time washing, has no destroys to the self structure of the ribbon, and is widely applied; and the production method is simple.

Description

technical field [0001] The patent of the present invention relates to a webbing, in particular to an in-situ-based preparation method for an antibacterial webbing. Background technique [0002] Ribbon is made of various yarns and elastic core wires as narrow fabrics or tubular fabrics. It is widely used in various industrial fields such as clothing, shoe materials, luggage, industry, agriculture, military supplies, and transportation. , the webbing is mainly used as bra shoulder straps or underwear elastic bands, usually it is in direct contact with the skin, so the webbing in the field of clothing is required to have softness and breathability requirements, and the soft and hygroscopic properties of cotton fiber make it the most commonly used webbing fiber. [0003] However, although the cotton fabric made of cotton fiber is comfortable to wear, it has a large specific surface area and strong moisture absorption capacity, which makes cotton products easy to attach microorg...
