Description
Technical Field
The invention belongs to the technical field of fabrics, and particularly relates to an antibacterial non-woven fabric.
Background
Nonwoven fabrics are a modern material industry with a wide range of applications, with a remarkable rate of development, and are known as the "sun-facing industry" in the textile community, with a high technical content in flexible material production systems, with a wide range of market demands. Although the non-woven fabrics produced by different processes have excellent effects in improving sanitary environment and being convenient to use. However, human skin and clothes are sites where bacteria grow, and the bacteria continuously propagate by taking human excretions such as urea in sweat as a nutrient source, and simultaneously emit ammonia with very strong odor, so that the health of people is affected and the people are unhygienic.
The antibacterial non-woven fabric is a non-woven fabric product widely applied to the fields of sanitation and medical treatment, and is generally prepared from materials such as terylene, polypropylene, chinlon, spandex, acrylic fiber and the like. The main component of the acrylic fiber is polyacrylonitrile, and the polyacrylonitrile fiber has a plurality of excellent characteristics, and enjoys the name of 'synthetic wool' according to the characteristics of softness and good warmth retention of the fiber; in addition, the polyacrylonitrile fiber has excellent light resistance, corrosion resistance, radiation resistance and organic solvent resistance, and is suitable for being applied to the field of non-woven fabric production.
The antibacterial mechanism of the metal ion antibacterial agent is realized through metal ion contact reaction: when positively charged metal ions are contacted with negatively charged cell membranes of microorganisms, coulomb attraction is generated between the positively charged metal ions and the negatively charged cell membranes, and the metal ions can penetrate through the cell membranes to enter the bacteria to react with amino or sulfhydryl groups on proteins in the bacteria, so that the cell protein structure is destroyed, and the microorganisms die or lose the division and proliferation capacity. Among them, silver ion antibacterial agents are preferable.
However, the existing silver-loaded antibacterial non-woven fabric is poor in washing fastness, and silver nano particles can fall off after being washed for a plurality of times, so that the antibacterial performance of the antibacterial non-woven fabric can be greatly reduced, and the application of the antibacterial non-woven fabric is greatly limited.
