Development Status And Development Trend Of New Textile Fibers

All countries in the world are developing

High functional fiber

High performance fiber mainly refers to fibers that can pmit light, electricity, adsorption, ultrafiltration, dialysis, reverse osmosis, ion exchange and other special functions. It also provides special functions such as comfort, health care, safety and other suitable fibers for special conditions.

There are mainly functional fibers, such as optical fiber, glass fiber, biodegradable fiber, ceramic fiber, conductive fiber, hollow fiber separation membrane, antibacterial fiber, radiation shielding fiber, high temperature resistant fiber and so on.

Ceramic fiber ceramic fiber is a kind of inorganic refractory fiber, which refers to the fiber made of ceramic material infiltrated into fiber polymer.

The range of ceramic fibers is very wide, including fibers made of metal oxides, carbides, nitrides, alumina, aluminum silicate, silicon carbide, boron nitride and potassium titanate.

Fiber matrix can be polyester, polyamine, polypropylene, polyethylene, etc., according to different uses, different ceramics can be selected.

Ceramic fiber has many advantages, such as high temperature resistance, corrosion resistance, high strength, high modulus, small thermal conductivity, thermal shock resistance and low heat capacity. It has been widely used in such fields as metallurgy, chemical engineering, building materials, aerospace, automobile and other industries in such fields as fire resistance, heat insulation, fire protection, high-temperature filtration and labor protection.

3. the main components of glass fiber glass are silica and other metal oxides, which are spun under melt.

Glass fiber has many advantages, such as rich raw materials, mature manufacturing process, low price, non combustible, corrosion resistant, high heat resistance, high strength and good insulation performance. It has wide application in industry.

4. biodegradable fiber biodegradable fiber refers to fibers that are self degradable in nature under the action of photothermal and microorganism.

Natural fiber itself is degradable, and synthetic fiber is firm and non rotting. Therefore, the waste of synthetic fiber is causing serious environmental pollution problems. Biodegradable synthetic fiber is the focus of improving the degradability of chemical fibers.

At present, chitin and chitosan fibers are widely used in medical materials.

They are fibers made from chitin or chitosan solution. Chitin is a natural biological polymer extracted from the shell of shrimp, crab and insect. Chitosan is the product of chitin deacetylated after strong alkali treatment.

Chitin and chitosan fiber not only have good physical and mechanical properties, but also have good biological activity.

The fiber is nontoxic and biodegradable, which can be degraded by human lysozyme and absorbed completely by human body. They can be used as medical suture and medical gauze, non-woven fabric or film dressing.

Another biodegradable fiber is polylactic acid fiber.

Polylactic acid is a product of milk fermentation. Its melting point is more than 180 degrees. It can be processed by melt spinning. The fabric has luster and dry touch. It is a good clothing material. It can be properly resolved in one year under the action of microorganisms in water or soil.

5. hollow fiber separation membrane hollow fiber separation membrane is a kind of functional fiber, its base material is viscose fiber, polypropylene fiber, polyester fiber and so on. According to its pore size characteristics, it can be divided into microfiltration membrane, ultrafiltration membrane, reverse osmosis membrane, ion exchange membrane and gas separation membrane.

The hollow fiber membrane made of textile technology can be assembled into blood filters, hemodialyzer, plasma separator and various purifiers for water preparation, liquid preparation, waste water treatment, seawater desalination and so on.

6. conductive fiber conductive fiber refers to the fiber in the standard condition (20 degree C, relative humidity 65%), and the mass ratio is less than 1081 ohm g/cm2.

The principle of conduction is that the fiber contains free electrons and no humidity dependence. Even under low humidity conditions, conductivity is not changed.

The elimination and antistatic properties of conductive fibers are much higher than those of antistatic fibers.

The earliest conductive fibers are conductive metal fibers made of conductive properties of metal. The conductive properties, heat resistance and chemical corrosion resistance of these fibers are good, but they are difficult to manufacture. In addition, the metal spraying method makes the fibers have the same electrical conductivity as metal. The current conductive fiber is added with some metal compounds into the fibers by adsorption or chemical reaction to form conductive fibers with good conductivity.

Conductive fibers are usually used to make Antistatic Fabrics, which can effectively prevent local accumulation of static electricity. The products made of conductive fibers can be used to produce explosion-proof work clothes, dustproof work clothes and antistatic blanket.

7. other functional fibers have many functional fibers, including flame-retardant fibers, which are made of flame retardants in polymers. Optical properties include light discoloration fibers, fluorescent fibers, thermochromic fibers and wet hot discoloration fibers. In addition, there are functional fibers such as magnetic fibers, far-infrared fibers, UV resistant fibers, negative ions, antibacterial fibers, and ion exchange fibers.
