Problems solved by technology

[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

Abstract

The invention discloses an environment-friendly antibacterial and flame-retardant hydrophobic fabric. The fabric is prepared by using flame-retardant modified cellulose fiber as a fiber raw material, and grafting carboxyl groups with metal ions so that the surface of the cellulose fiber is loaded with metal. ions, so as to improve the flame-retardant properties of flame-retardant modified cellulose fibers, by uniformly spraying a layer of polyvinyl alcohol modified material on the surface of flame-retardant modified cellulose fibers, and then curing it, so that the flame-retardant modified A layer of polyvinyl alcohol modified material film layer is formed on the surface of the cellulose fiber to obtain an environmentally friendly antibacterial flame retardant hydrophobic fiber, and then the fiber is used as a raw material to prepare an environmentally friendly antibacterial flame retardant hydrophobic fabric, antibacterial flame retardant filler When added to polyvinyl alcohol modified materials, it can improve its flame retardancy and antibacterial ability, and the materials used are all degradable and non-polluting, which greatly improves the environmental protection of the fabric.

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...
