Fuctional Fiber Traditional textile industry

The development of functional fibers is a symbol of modern fiber science progress. The development of functional fibers, differentiated fibers and high-performance fibers has created favorable conditions for the technological innovation of the traditional textile industry and the transformation of high-tech industries, and has contributed to the improvement of human living standards. Functional fiber refers to the general fiber in addition to the physical and mechanical properties, but also has a special function of the new fiber. Protective effect (radiation, anti-static, anti-ultraviolet, etc.); hot and humid comfort function (endothermic, exothermic, moisture absorption, wetting, etc.); Etc.); medical and environmental protection functions (biocompatibility and biodegradability).

Special fibers with some special function. The so-called special function, refers to the reverse osmosis, separation of mixed gas, dialysis, ultrafiltration, adsorption, oil absorption, ion exchange, efficient filtration, light and conductive. Functional fibers with their respective special features, in the industry were the corresponding application. Functional fibers are broadly divided into five categories:

The pore structure of the hollow fiber hollow fiber membrane diameter between 1 to 10 angstroms, with reverse osmosis, can be made of reverse osmosis device for the separation of very small particle size of metal ions and low molecular weight substances, especially for Desalination in seawater desalination. Materials for the production of hollow fibers are: aromatic polyamide, polyhydrazide, cellulose triacetate, polyester, polycarbonate, polysulfone and the like. Such as aromatic polyamide, polyhydrazide as a hollow fiber, after dry - wet spinning made of reverse osmosis, the desalination effect of seawater can be as high as 98% or more, that is, once a sea water treatment can achieve drinking water quality. Hollow fiber membrane diameter of 10 Å to 3 microns, with ultrafiltration and dialysis properties, can be used for certain polymer coatings, latex, fiber oil, protein, enzymes and other solutions for concentration, recovery or refining , In the medical or electronics industry can be used as ultra-pure water filter, artificial kidney dialysis membrane. This type of hollow fiber material is copper ammonium fiber, cellulose triacetate, polyacrylonitrile, polymethyl methacrylate, polyvinyl alcohol and polysulfone. Generally used dry-wet spinning forming, in the center of the fiber into a certain component of the coagulation fluid to form a porous structure of the tubular fiber. Polyethylene or polypropylene hollow fiber membranes with microporous membrane walls can be used to separate mixed gases as well as ultrafiltration and dialysis.

Fiberglass and non-woven fabrics Select an electrostatic large perchlorethylene or polyvinyl chloride, high-frequency electrostatic spinning or electrostatic - high-speed air jet, that is, the formation of ultra-fine fiber mats, can be used to filter radioactive dust and other aerosols, filtration efficiency Up to 99.999% or more, can also be used as a dust or sterile room filter. Selection of acid or alkali resistance of polyamide, polyester or polypropylene with melt gas jet processing, available ultra-fine fiber non-woven fabrics, can be used as a variety of micro-battery separator. Selection of lipophilic polypropylene or polystyrene made of non-woven fabrics, can be used as oil-absorbing materials, adsorption of water on a certain thickness of the oil layer, oil absorption capacity can be up to ten times their own weight.
