[0003] In the prior art, a large number of fabrics are prepared from petroleum derivatives. On the one hand, it will consume a large amount of fossil energy, on the other hand, it will cause harm to the environment, and most of the fabrics widely used in various fields are combustible. Sometimes it will become a substance that accelerates the spread of fire, so flame-retardant fabrics are widely used in many fields, but in the prior art, in order to ensure that the fabric has good flame-retardant properties, it is usually mixed in the fiber raw materials when preparing fibers. Flame retardant or coating a layer of flame retardant coating on the surface of the formed fiber, both of which will have a significant impact on the softness and other properties of the fiber, affecting the range of use of fabrics made of this type of fiber. The flame retardant will also cause harm to the environment, and washing with water will also cause the flame retardant to fall off. In order to provide a degradable environmentally friendly antibacterial and flame-retardant hydrophobic fabric, the present invention provides the following technical solutions

Embodiment 1
[0036] An environment-friendly antibacterial and flame-retardant hydrophobic fabric is prepared by the following method:
[0039] S1. Prepare a modified polyvinyl alcohol aqueous solution with a mass concentration of 2.2%, prepare a chitosan aqueous solution with a mass concentration of 6%, wherein the degree of deacetylation of chitosan is greater than or equal to 90%, and the two are in a weight ratio of 1:0.8 Stir and disperse for 60 minutes at a rotating speed of 240r / min, and after vacuum defoaming, obtain a uniform mixture of polyvinyl alcohol aqueous solution and chitosan aqueous solution, that is, the matrix solution;
[0040] S2. After heating the matrix solution to 80°C, add antibacterial and flame-retardant fillers to it, and then mix and stir for 2 hours at a speed of 460r / min to obtain a polyvinyl alcohol modified material, wherein t...

Abstract
The invention discloses an environment-friendly antibacterial flame-retardant hydrophobic fabric. The environment-friendly antibacterial flame-retardant hydrophobic fabric is prepared by taking flame-retardant modified cellulose fibers as a fiber raw material and grafting carboxyl and metal ions to enable the surfaces of the cellulose fibers to be loaded with the metal ions, so that the flame-retardant performance of the flame-retardant modified cellulose fibers is improved. The surfaces of the flame-retardant modified cellulose fibers are uniformly coated with a layer of a polyvinyl alcohol modified material, and then curing is performed, so that a polyvinyl alcohol modified material film layer is formed on the surfaces of the flame-retardant modified cellulose fibers, and the environment-friendly antibacterial flame-retardant hydrophobic fabric is prepared. The environment-friendly antibacterial flame-retardant hydrophobic fabric is processed and prepared by using the fibers as the raw material, and an antibacterial flame-retardant filler is added into the polyvinyl alcohol modified material, so that the flame-retardant capacity and the antibacterial capacity can be improved, theused materials are degradable and pollution-free, and the environmental protection property of the fabric is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of production of environment-friendly fabrics, and in particular relates to an environment-friendly antibacterial and flame-retardant hydrophobic fabric. Background technique [0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. With the improvement of living standards, people have more requirements for fabrics. [0003] In the prior art, a large number of fabrics are prepared from petroleum derivatives. On the one hand, it will consume a large amount of fossil energy, on the other hand, it will cause harm to the environment, and most of the fabrics widely used in various fields are combustible. Sometimes it will become a substance that accelerates the spread of fire, so flame-retardant fabrics are widely used in many fields, but in th...
