According to statistics, there is a huge space for development in the field of disposable products in China. With the continuous improvement and improvement of people's living standards, consumers pay more attention to the safety of textiles closely related to their own lives. Therefore, it is urgent to continuously develop new antibacterial products with long-lasting, broad-spectrum, high-efficiency and non-toxicity.

Up to now, there have been nearly 100 kinds of natural, organic and inorganic antibacterial agents in China, but the results show that these antibacterial agents have antibacterial efficiency, speed, broad spectrum, long-lasting and heat resistance, compatible mixing and processing properties. With varying degrees of defects, as the field of nonwovens continues to expand, the market calls for the development of more durable, more efficient, non-toxic antibacterial products.

After continuous efforts, Shanghai Petrochemical has developed a new type of functional polypropylene staple fiber - antibacterial polypropylene staple fiber, and achieved outstanding results.

Its production principle is to repeatedly test fiber-grade PP chips, spinning oil (cotton polypropylene fiber), (polypropylene fiber for non-woven fabric) and different antibacterial agents. The results show that organic antibacterial agent (KJY- 1) The quality index of inorganic antibacterial agent (KJW-1) fiber is similar to that of pure PP fiber. It can be used to spun fiber for antibacterial polypropylene fine denier cotton and non-woven fabric. It has been tested by Shanghai Institute of Preventive Medicine and has strict acute toxicity. The test and skin irritation test prove that the two antibacterial agents are safe and non-toxic to humans, and have no irritation to the skin and no allergies. The antibacterial polypropylene staple fiber is widely used in hospitals, rehabilitation hospitals and other susceptible places. It is also suitable for disposable sanitary napkins, baby diapers, and incontinence products for the elderly. It can also be used as air conditioners, dehumidifiers, environmental protection and industrial filter materials. It has been proved that when air or liquid is made through antibacterial polypropylene nonwoven fabrics. After the filter material, the bacteria will be adsorbed and inhibited, effectively extending the service life of the filter material and improving the cleaning quality of the filtered air and liquid; Antibacterial polypropylene non-woven fabric material can effectively inhibit bacterial fungi and eliminate athlete's foot and foot odor caused by bacterial infection. At the same time, the demand for such products in the field of antibacterial decoration products is also great, and can be used for home carpets, trains, Car carpets, sportswear, underwear, T-shirts, pajamas, hotel bedding, towels, decorative fabrics and many other fields.

At present, antibacterial polypropylene fiber is widely used in developed countries. The successful development of this new type of antibacterial polypropylene staple fiber in China has brought a new step in the development of antibacterial nonwovens in China. According to the data, 52% of consumers in developed countries in the world will pay attention to whether the products have antibacterial function and pay more attention to the safety of the products when purchasing non-woven fabrics and textiles. Therefore, the application of antibacterial polypropylene staple fiber in China is very broad.
