Along with the age that the 21 st century we advocate low carbon and environmental protection, the textile industry also strives to reform and innovate; on the basis of the original textile industry, the innovation of the product is focused, and the development is made to the aspects of more multifunction, low cost and green environmental protection.
Nowadays, products which have health concepts, meet environmental protection requirements and market fashion trends in the textile field are always the favourites of consumers, and cool mineral yarns are generated in the concept, so that the functions of moisture absorption, sweat release and cool feel are required by the current market. Meanwhile, various functional composites are also a trend in the development of new textile materials.
Mica is a widely-distributed rock-making mineral, and has various good characteristics of elasticity, toughness, insulativity, high temperature resistance, acid and alkali resistance, corrosion resistance, strong adhesive force, strong hydration, high refraction brightness and the like. At present, the material is mainly applied to building materials, plastics, papermaking, welding materials, electric insulation and the like at home and abroad. The polyester carrier added with mica has the fiber section subjected to special-shaped treatment, and more capillary channels are arranged among the fibers, so that the fiber is a new generation of cooling and heat dissipation fiber material and has the effects of natural cooling, moisture absorption and quick drying.
The development and application of the mica fiber serving as a novel fiber in the domestic and foreign markets are just started, and particularly the production and application in the textile field are not developed on a large scale, the developed mica fiber is small in variety and limited in quantity, and most of the mica fibers are in the experimental stage of trial spinning and trial production of the mica fiber, and mica is firstly applied to composite materials for paints, inks, cosmetics and building site safety nets by Dupont and Japanese company in the United states. In recent years, the national Yueyang petrochemical industry general institute, the south China university, the university of Wuhan and the university of Wuhan engineering and other institutions research the use of mica and fiber combination as the enhancement of the system strength of objects. The research and development application of the mica fiber as a novel fiber in the textile field is just started, for example, the mica nylon cool fiber filaments are invented by Taiwan, jiangsu, shanghai and other scientific and technological companies, and the mica fiber is developed; the yarn for knitting of combed cotton/mica fiber is developed by manufacturers, but is not successfully applied to the industrial production of final products in the textile field.
The mica fiber can be blended with cotton, wool, silk, hemp and chemical fiber short fibers, can be spun purely, has the characteristics of health care, antibiosis and cooling, has good dyeing property and wear resistance, can be used for manufacturing various textile products such as underwear, body shaping clothes, socks, bedclothes, automobile cushions and the like, meets the multidirectional requirement that people integrate functions such as comfort, leisure, health care and the like on the textile, further enriches the varieties of textile materials in China, and has good development prospect.
The mechanism of the antibacterial cooling modified mica yarn is that zinc particles and mica sheets with moisture absorption and heat conduction are added in the spinning process by a nano technology, two different carriers of terylene and chinlon have been developed, the excellent heat conductivity of mica is utilized to exert cooling function, the antibacterial function of the nano zinc particles and an electrostatic shell layer at the outer layer are utilized to generate a positive electric field, and the metabolism of bacteria can be effectively inhibited or stopped, so that the antibacterial cooling double-effect is achieved.
Therefore, how to reasonably match the antibacterial and cooling modified mica polyester filaments with other fibers, and a novel and reasonable fabric structure is adopted to research and perfect a mature weaving process, so that the advantages of different fibers are complementary, the organic combination of antibacterial and cooling is achieved, and the taking requirement of low carbon and environmental protection is met.
