Problems solved by technology

The current antibacterial fiber adopts the original silk modification method and post-treatment method. Among them, the original silk modification method will produce wool and broken ends, and fibers with better smooth hand feeling cannot be obtained; post-treatment will use some antibacterial agents, especially some metals. Elements such as lead and copper exist in the fiber, because they will be in contact with the human body and will cause certain harm to the human body; in addition, some antibacterial agents treat the surface of the fiber by impregnation, adsorption, etc., and the fiber has been washed many times , it may also cause the antibacterial agent to fall off, and the antibacterial effect will be reduced
Through the above analysis, it is not difficult to find the defects of the prior art

Abstract

The invention relates to a nanometer bamboo charcoal antibacterial fiber and a method for producing the same, in particular to a melt-spinning method for producing the nanometer bamboo charcoal antibacterial fiber. The nanometer bamboo charcoal antibacterial fiber consists of nanometer bamboo charcoal, nanometer silver and a carrier slice, wherein the carrier slice is one of terylene, polypropylene fiber or chinlon. An antimicrobial master batch is prepared first and is mixed with the carrier slice according to certain proportion, and then the mixture is used for preparing the required nanometer bamboo charcoal antibacterial fiber through the melt-spinning method. The nanometer bamboo charcoal antibacterial fiber has the advantages that the bamboo charcoal is a renewable resource which is rich, can be produced through adjusting part of the process conditions by using the prior equipment, and passes test and detection with the antibacterial rate of more than 98 percent; and the nanometer bamboo charcoal antibacterial fiber is not only applied in the aspect of dress, but also widely applied to transportation, environmental protection, medical treatment and other industries.

Description

【Technical Field】 [0001] The invention relates to an antibacterial fiber, especially a nano bamboo charcoal antibacterial fiber and a manufacturing method thereof. 【Background technique】 [0002] Today, when environmental pollution is getting more and more serious, there are all kinds of bacteria in our living environment. This requires us to strengthen our protection, and in this regard, our most basic protection is our daily use of underwear, socks, jackets, sheets, quilts and other related apparel products. Nowadays, as people's requirements for clothing are getting higher and higher, clothing made of antibacterial fibers will be welcomed by people. At the same time, due to the continuous reduction of petroleum resources, renewable resources are getting more and more development, especially the requirements of environmental protection. The bamboo charcoal has a wide range of sources, is simple to prepare, and meets the requirements of environmental protection. The most importa...
