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 add

Abstract

The invention relates to a nanometer bamboo charcoal viscose antibacterial fiber and a method for producing the same, in particular to a wet-spinning method for producing the nanometer bamboo charcoal viscose antibacterial fiber. Nanometer bamboo charcoal antibacterial liquid slurry is prepared after mixing nanometer silver and nanometer bamboo charcoal. The nanometer bamboo charcoal antibacterial liquid slurry is mixed with alpha cellulose to prepare the nanometer bamboo charcoal viscose antibacterial fiber through the wet-spinning according to a viscose process production method. The nanometer bamboo charcoal viscose 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 through a test and a detection with the antibacterial rate of more than 98 percent; and the nanometer bamboo charcoal viscose antibacterial fiber has stronger handfeel than that of the prior terylene, and better comfort in wearing and use, and is widely applied to transportation, environmental protection, medical treatment and other industries.

Description

【Technical field】 [0001] The invention relates to an antibacterial fiber, in particular to a nanometer bamboo charcoal viscose antibacterial fiber and a manufacturing method thereof. 【Background technique】 [0002] In today's increasingly serious environmental pollution, there are all kinds of bacteria in our living environment. This requires us to strengthen our own protection, and in this regard, our most basic protection is our daily use of underwear, socks, coats, bed sheets, quilt covers and other related clothing 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, more and more renewable resources have been developed, especially the requirements for environmental protection. Bamboo charcoal has a wide range of sources, is simple to prepare, and meets the requirements of environmental protectio...
