Problems solved by technology

However, since the C atoms on the graphene carbon network plane are sp2 hybridized to form a stable six-membered ring crystal structure, the force between the sheets is strong, which makes graphene poor in dispersibility and difficult to dissolve in water and most organic compounds. Therefore, traditional graphene products are produced by blending spinning method and composite spinning method, that is, when spinning and spinning, graphene particles or powders are added to chemical fiber particles in a certain proportion, and then through spinning Obtained by spinning, the carrier includes polyester, nylon, polypropylene, viscose filament, etc., which makes graphene finishing difficult, and the effect is poor, the antibacterial effect lasts for a short time, and it is not washable

Embodiment 1

[0033] 1 Preparation method

[0034] This embodiment provides a method for preparing water-resistant 5A antibacterial and antiviral graphene fibers, which is prepared by a dipping process, specifically including the following steps:

[0035] S1: Antibacterial and antiviral treatment is carried out on the raw fiber or fiber fabric to obtain antibacterial and antiviral fiber or fiber fabric, specifically including:

[0036] Step (1): The raw material fibers or fiber fabrics are boiled and bleached in the pretreatment working solution to produce reactive free radicals. Specifically, take 20g of raw material fibers or fiber fabrics and place them in a 300cc jar In the middle, the cylinder cup is equipped with a pretreatment working solution: 50% hydrogen peroxide 4g / L, 100% sodium hydroxide 4g / L, scouring agent 2g / L, and the yarn is reacted at 100°C at a bath ratio of 1:10 60min, obtain the raw material fiber or fiber fabric with better capillary effect, and described refining ag...

Embodiment 2

[0070] This embodiment provides a method for preparing water-resistant 5A antibacterial and antiviral graphene fibers, which is prepared by a padding process, and specifically includes the following steps:

[0071] S1: Antibacterial and antiviral treatment is carried out on the raw fiber or fiber fabric to obtain antibacterial and antiviral fiber or fiber fabric, specifically including:

[0072] Step (1): The raw material fibers or fiber fabrics are boiled and bleached in the pretreatment working solution to produce reactive free radicals. Specifically, take 20g of raw material fibers or fiber fabrics and place them in a 300cc jar In the middle, the cylinder cup is equipped with a pretreatment working solution: 50% hydrogen peroxide 4g / L, 100% sodium hydroxide 4g / L, scouring agent 2g / L, and the yarn is reacted at 100°C at a bath ratio of 1:10 60min, obtain the raw material fiber or fiber fabric with better capillary effect, and described refining agent is selected from prior a...

Abstract

The invention relates to the technical field of light industry textile, in particular to a preparation method of washable 5A-grade antibacterial and antiviral graphene fiber and a fiber product. The preparation method comprises the following steps: firmly combining an antiviral group and an antibacterial group on the fiber in a chemical bond manner by grafting modification and chemical modification methods, so as to obtain modified fiber with antibacterial and antiviral properties; reprocessing the modified fiber by a dipping method and a padding method through graphene finishing liquid so as to obtain the antibacterial and antiviral graphene fiber or fiber fabric. The fiber or fiber fabric and the fiber product prepared from the fiber or fiber fabric have antibacterial and antiviral effects, have various advantages of graphene fabric, and can be widely applied to the fields of infant products, underwear, bedding articles, homewear, home textile towels, socks, masks, medical supplies, health and epidemic prevention, military supplies and business.

Description

technical field [0001] The invention relates to the technical field of light industry textiles, in particular to a preparation method of water-resistant 5A grade antibacterial and antiviral graphene fibers and fiber products. Background technique [0002] In recent years, with the improvement of people's living standards and the enhancement of health awareness, the market demand for antibacterial products continues to rise. Consumers have gradually transformed from the initial pursuit of warmth and comfort to the pursuit of functionality, safety and health. Antibacterial textiles are one of the most popular functional textiles in the textile market today. The recurrent attacks of infectious inflammation are mostly caused by the "not clean enough" underwear. This "unclean" does not mean that the clothes are not cleaned properly, but that there are many viruses and bacteria on the clothes that are invisible to the naked eye. It is difficult to avoid germs on clothes in dail...
