Chitosan has become a new favorite in the raw material market for health care functional textiles

Chitosan is becoming a new highlight of the raw materials of health care products, which not only guides the research and development of functional foods, but also becomes a "new trend of food research", but also becomes the mainstream of healthy fashion consumption in the consumption of functional clothing, accessories, household and other daily necessities. At the "Hanchen Shimei 2015 Health Functional Textiles Annual Conference and New Product Launch Press Conference" held in Hanchuan, Hubei Province on December 26, 2014, Zhou Bangyong, deputy secretary general of the China Health Care Association, said that due to the unique biological characteristics of chitosan fiber, the health care power spinning fabric produced from it has a broad market application space, and the future development will be unlimited.

Chitosan is a kind of biological polymer substance obtained by chitin after deacetylation, chitin is mainly derived from shrimp shell and crab shell, is the only, alkaline, positively charged natural polysaccharide organic matter found in nature, a renewable natural resource, can be naturally degraded, will not cause pollution to the environment, chitin can be obtained after deacetyl treatment. Chitosan fiber takes chitosan as the main raw material, dissolves it in an appropriate solvent, prepares it into a certain concentration of colloidal spinning liquid, and then prepares chitosan fibers by spinning, solidification, stretching and other processes.

Professor Chen Shaojuan of Qingdao University said that chitosan comes from nature, has good biocompatibility, non-toxicity, at the same time, chitosan can be hydrolyzed into the corresponding glucosamine by enzymes in the human body such as lysozyme, which is absorbed by the human body, so it has good biodegradability. It is widely used in agriculture, makeup industry, environmental protection industry, health care industry, food industry, textile industry, medical field and other aspects.

Although chitosan fiber has good antibacterial properties, its strength is low and the price is high, and it is not suitable for large amounts of addition. How to evenly increase a certain amount of fiber in non-woven fabrics is always a technical problem. In this regard, Liu Xiaohui, chairman of Hainan Litian Industrial Co., Ltd., told the Science and Technology Daily reporter that the Lismier series of chitosan non-woven fabrics they developed and will be listed soon, with its unique technology, the appropriate amount of chitosan fibers are evenly added to the non-woven fabric, so that it has good antibacterial properties, but also light, thin, transparent, at present, Hanchen Shimei health care functional textile products after scientific research and development of chitosan, in the mask, diaper is not wet, sanitary napkins and pads, electromagnetic shield maternity wear, baby and child clothing, There are related applications in antibacterial underwear such as scarves and health care.

Industry insiders said that at present, China's major mask manufacturers are competing to use silk mask paper produced by Japanese and American companies, resulting in a shortage of supply in the market, and the factory continues to raise the price of raw materials. The birth of the Lischmel series of non-woven fabrics will break this market monopoly and supply the best quality mask base cloth to Chinese mask enterprises in unlimited quantities.

Data show that in 2009, the output value of the health care functional textile industry was about 32.15 billion yuan, and it increased at a rate of 20% per year, and it is expected that the market size will reach 100 billion yuan by 2015. Moreover, the development of functional textiles shows the following trend, that is, the application and functionalization of multiple high-tech and special fibers of fiber raw materials, the compounding of fiber structure and performance, and the compounding of textile multi-functional functions.

New products brought by new technologies make the market bigger cake, enhance economic restructuring and transformation will play a positive role, who grasps the technical core of new health care materials, who occupies the leading right of the health care industry and market.

Professionals pointed out that according to the health and functional needs, the molecular structure of the fiber, the material collocation and the cross-sectional form of the textile performance can strengthen the functionality of the textile. Nowadays, single-function products can no longer meet the market demand, a variety of functions of the composite, new specialization and high simulation series of products to become the focus of the development of functional products in the future; the use of a new generation of high-tech fibers, including temperature color-changing fibers, light-color-changing fibers, fragrance fibers, thermal insulation and storage fibers, high water absorption, antistatic, low melting point, conductivity and moisture conductivity, waterproof and breathable and other functional fibers, the development of textiles with specific functions, the use of biotechnology to develop more new functional textile materials, such as spider silk protein fiber, Mulberry leaf protein fiber and so on. The birth of Lischmel fiber is expected to completely solve the application problems of chitosan with natural antibacterial effects in various fields, and the application of new materials for health textiles is a new technological revolution, and Lischmel will become the leader of chitosan as a raw material in the health functional textile market.

It is reported that as an entrepreneur from Hanchuan, Hubei Province, Liu Xiaohui hopes to make a contribution to the development and construction of his hometown. To this end, he plans to invest in the establishment of a production base in Hanchuan, specializing in the production of health functional textile raw materials - Lischmel fiber. At present, the first phase of 200 acres of land is under planning and preparation.
