Problems solved by technology

[0003] Moreover, because the application of fabrics is closely related to people's daily life, and as a wearable product, it is common to be in contact with the skin. Therefore, people's requirements for the antibacterial performance of fabrics are getting higher and higher. Nowadays, fabrics have begun to appear on the market. Some fabrics with antibacterial function have been introduced, but because the fabric itself is easy to absorb and breed bacteria and fungal microorganisms, especially in underwear and medical fabrics, if the antibacterial effect is not good, it will greatly affect personal health, so it can be improved. The flammable properties of pre-cellulose fibers and the cellulose fabrics with antibacterial properties have become a research hotspot in this field.

Abstract

The invention relates to a preparation method of a cellulose fabric having antibacterial and inflaming-retarding functions, belonging to the field of production of textiles. The preparation method comprises the following steps: dissolving chitosan phosphate into a butanetetracarboxylic acid solution, adding sodium hypophosphite having catalytic amount into the solution to prepare fabric treatment fluid, and dipping the cellulose fabric into the fabric treatment fluid, taking out and rolling for drying the fabric. According to the technical scheme, sodium hypophosphite is used as a catalyst, chitosan phosphate is dissolved into butanetetracarboxylic acid to be prepared into the fabric treatment fluid, and the cellulose fabric is dipped into the fabric treatment fluid, is taken out and is rolled to be dried, thus, the cellulose fabric has antibacterial and inflaming-retarding functions and has remarkable beneficial effects.

Description

technical field [0001] The invention relates to a preparation method of a cellulose fabric with antibacterial and flame-retardant functions, belonging to the field of textile production. Background technique [0002] The application fields of fabrics are extremely wide, such as clothing fabrics, decorative fabrics, automotive fabrics, industrial fabrics, medical fabrics and aerospace military fabrics, etc., which are widely used in various fields related to the national economy and people's livelihood. Due to the low thermal stability of cellulose fibers , at 300°C to 400°C, it can be dehydrated to produce aliphatic and depolymerized to produce levoglucosan and then pyrolyzed. Levoglucosan decomposition products have high flammability and low molecular weight, and the oxidation heat can support the further development of cellulose. Pyrolysis. [0003] Moreover, because the application of fabrics is closely related to people's daily life, and it is common for wearable produc...
