Has some special features of the special Fabric bread basket . The so-called Oven Mitt and Potholder Set special features refers to reverse osmosis, mixed gas separation, dialysis, ultrafiltration, absorption, oil absorption, ion exchange, high efficiency filter, such as guided light conductive. Functional fiber with its own special features, corresponding, respectively, in the industrial application. Functional fibers can be divided into five categories:

Microporous structure of the hollow fiber membranes of microporous hollow fiber diameter of 1 to 10 angstroms, with reverse osmosis, can make the reverse osmosis device for the separation of very small size of the metal ions and low molecular weight substances, especially for in desalination desalination. Manufacture of hollow fiber materials include: aromatic polyamide, polyethylene hydrazine, 3 cellulose acetate ester, polyester, polycarbonate, polysulfone, etc.. Such as in aromatic polyamide, polyethylene hydrazine as hollow fibers, through the dry - wet spinning forming device made of reverse osmosis, desalination of seawater up to 98% effect, that a deal can be reached through the water quality of drinking water. Microporous hollow fiber membrane diameter of 10 to 3 microns and Egypt, it has the characteristics of ultrafiltration and dialysis can be used on some of the polymer coating, latex, fiber oil, proteins, enzymes, acids concentration, recovery or refining , in the medical or electronic industry can be used as ultra-pure water filters, artificial kidney dialysis membrane. This type of hollow fiber material with copper ammonium fibers, triacetate cellulose acetate, polyacrylonitrile, polymethyl methacrylate, polyvinyl alcohol, and polysulfone, etc.. Commonly used wet - spinning forming the center of the fiber access certain components of coagulation liquid to form a porous structure of tubular fibers. Microporous membrane with the walls of polyethylene or polypropylene hollow fiber membrane for the separation of gas mixture can also be used as ultrafiltration and dialysis.

Non-woven fabric mat and a large selection of over static vinyl or PVC, by electrostatic spinning or static - high-speed air jet, the formation of ultra-fine fiber mat that can be used to filter radioactive dust and other aerosols, the highest filtration efficiency 99.999%, and also be used as the filter clean or sterile room. Good use acid or alkali polyamide, polyester or polypropylene with melt flow jet process, the availability of non-woven microfiber cloth can be used as a variety of micro-battery separator. Use a large hydrophobic polypropylene or polystyrene nonwoven fabric manufactured, used as oil-absorbing material, a certain thickness of the reservoir surface adsorbed water, oil absorption capacity of up to ten times its own weight.

Microporous structure of activated carbon fibers, the surface has a strong absorption feature can be used for some of the gas, liquid adsorption, recovery, deodorizing, decolorizing, refining, separation equipment such as filters and artificial organs, is also used for some chemical reaction catalyst carrier. The raw material for the cellulose fibers, polyacrylonitrile, or phenolic fibers after carbonization at high temperature high pressure steam activation obtained.

Ion-exchange fiber in the introduction of some of the macromolecular active groups, such as sulfonate, carboxyl, amine, thiol and other phosphate-based or fiber on a pair of heavy metal ions by ion exchange or capture function can be used for sewage treatment radioisotopes or heavy metal separation and recycling.

Optical fiber and conductive fiber of two different refractive index transparent material made by a special composite core technology sheath composite fibers, known as the optical fiber. This fiber optical performance. With high-purity silicon or transparent polymer (PMMA or polystyrene) as core material, transparent fluorinated resin, polyamide 12 and other materials for the sheath made of optical fiber, make light in the core Department of refraction conduction along the interface can be used as optical communication, data transmission, a variety of lighting and digital display. In the chemical fiber mixed with graphite or metal powder (such as copper, silver and nickel) and other conductive additives can be certain of the conductive fibers and antistatic properties, this fiber is conductive fiber. Mixed with additives in different ways: a configuration of the center of the fiber; have to fine ribbed scattered among the fibers; there is gold in the fiber surface layer; also have to like copper iodide absorption of metal compounds within the fiber. Than the resistance between conductive fiber carbon fiber and metal fibers, so this is actually the semiconductor fiber, can be used as clean clothing, live line work clothes, work clothes explosion-proof anti-static, carpet and other industrial materials. Most of these conductive fibers with a variety of dark colors, if used white metal compounds, may be obtained white fibers, used as a white uniform and with services such as hospitals.
