Problems solved by technology

However, graphene oxide and its derivatives are easily soluble in water, which will fall off from the surface of the fabric during the reduction process and dissolve in the reducing agent solution, resulting in a decrease in the utilization of graphene oxide. In addition, the anion used in the finishing process Surfactants are more polluting to the environment
[0005] It can be seen that in the prior art, the application of graphene in the field of textile fibers is mostly expensive, and the types of fibers targeted by some finishing methods are limited. At the same time, crosslinking agents and adhesives have to be used in the finishing process, which not only increases the production cost , and pollute the environment

Abstract

The invention relates to a graphene / polyvinyl alcohol modified nonwoven fabric production method, and belongs to the technical field of textile chemistry. The method comprises the following steps: dipping a nonwoven fabric in a graphene oxide / polyvinyl alcohol composite modification solution, drying the nonwoven fabric, and reducing graphene oxide to make the surface of the nonwoven fabric covered with a layer of reduced graphene oxide in order to obtain a nonwoven fabric product with excellent hydrophilic, antibiotic, antistatic and adsorptive functions. The method is suitable for modifying polypropylene fibers, terylene, polyamide, acrylic fibers, polyethylene fibers, polyvinyl chloride fibers, polytetrafluoroethylene, polyphenylene sulfide and other nonwoven fibers, and the nonwoven fabric product obtained in the invention can be used in fields of clothes, home textiles, medical health care, air purification, sewage treatment and military matters. The preparation method has the advantages of simplicity, low cost, wide application range and high application values.

Description

technical field [0001] The invention relates to a method for preparing a non-woven fabric with multiple functions such as hydrophilicity, antibacterial, antistatic and adsorption by using a graphene / polyvinyl alcohol modification liquid, belonging to the technical field of textile chemistry. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are widely used in clothing and home textiles, medical and health care, electronics industry, air purification, sewage treatment and other fields because of their excellent performance. Graphene has good electrical conductivity and is also an ideal non-porous adsorbent and antibacterial agent, which can be used as a new type of adsorbent and antibacterial material. [0003] The application of graphene in the field of textile fibers to prepare multifunctional materials such as antistatic, antibacterial, and adsorption is the development direction in recent years. The usual method is to add graphene to the ...
