Problems solved by technology

Although this kind of non-woven fabric has flame retardant properties, it also has shortcomings. First, the flame retardants that make up the flame retardant layer are all single components, and the flame retardant effect that can be played is limited, and it is difficult to Obtain significant flame retardant effect; secondly, only flame retardant effect, but no antibacterial function; thirdly, the preparation method cannot obtain a product with both significant flame retardant effect and antibacterial function

Abstract

The invention discloses a fabric with a flame-retardant function and an anti-bacterial function and a manufacturing method of the fabric. The functional fabric is formed by covering a fabric with more than one layer of polyhexamethylene guanidine salting layer and a polyphosphate salting layer on the polyhexamethylene guanidine salting layers. The manufacturing method includes the steps of dipping the fabric in a 0.05-5g / 100g polyhexamethylene guanidine saline solution for 10-120 seconds prior to taking out, washing with distilled water for 20-120 seconds, and drying at the temperature of 50-80 DEG C for 20-60 minutes to obtain the fabric with polyhexamethylene guanidine salting; dipping the fabric with the polyhexamethylene guanidine salting in a 0.05-5g / 100g polyphosphate saline solution for 10-120 seconds prior to taking out, washing with the distilled water for 20-120 seconds, and drying at the temperature of 50-80 DEG C for 20-60 minutes to obtain the fabric with the polyhexamethylene guanidine salting and polyphosphate salting; repeating the two steps for at least more than 0 time to obtain the fabric with the flame-retardant function and the anti-bacterial function. The fabric with the flame-retardant function and the anti-bacterial function is excellent in the flame-retardant function and the anti-bacterial function, is durable in quality and can be widely used in daily life of people.

Description

technical field [0001] The invention relates to a fabric and a preparation method, in particular to a fabric with flame-retardant and antibacterial functions and a preparation method thereof. Background technique [0002] Textile fabrics have been widely used in people's daily life, such as various cotton fabrics, hemp fabrics, chemical fiber fabrics, and their blended fabrics. These fabric materials are extremely flammable, and the flame spreads fast and is not easy to extinguish. At the same time, the dense smoke generated during the burning process also poses a huge threat to the natural environment and human life safety; in addition, the cellulose molecular chains in the fabric contain a large amount of Hydroxyl, therefore highly hygroscopic, provides a good living environment for the growth of bacteria. The bacteria they breed will not only pose a threat to human health, but also destroy the structure of cellulose by releasing acidic substances, causing the degradation ...
