functional fiber: does not change with the external environment

With the progress of human science and technology, the increase of population, the continuous improvement of people’s consumption level, the demand and requirements for clothing also develop to a higher level and requirements. 1n particular, the use of industrial textiles will expand, and the demand for textile fiber raw materials, special textile raw materials, and functional textile raw materials will increase significantly

1 functional textiles

refers to the textiles with special functions and super performance beyond the conventional textile products, such as covering, beautifying, etc. these functions do not change with the change of the external environment

for example, functional outerwear fabrics can be endowed with different functions according to different wearing occasions

for example, leisure clothing has the functions of antibacterial, deodorant, mildew proof, mite proof, self-cleaning, anti-static, anti ultraviolet, anti electromagnetic wave, washable (non ironing) and shrink proof

social and professional clothing has the functions of three Proofs (waterproof, oil proof, antifouling), antibacterial, deodorant, mildew proof, mite proof, self-cleaning, wrinkle resistant, anti pilling, self-cleaning, radiation proof, etc

sports clothing has the functions of anti-bacterial deodorization, moisture absorption and quick drying, anti mosquito, anti ultraviolet, and cold proof clothing has the functions of waterproof, moisture permeability, anti radiation, high toughness, washability, etc

functional underwear fabric has the functions of antibacterial deodorization, moth proof, mite proof, mould proof, far infrared, heating, negative oxygen ion, high moisture absorption and quick drying. These textiles with special functions are blended with excellent natural fiber cotton. Some of them have a single function, and some of them have several functions, which make them multi-functional composite textiles

compared with functional fabrics, the fabrics that have beneficial changes to human body with the change of external environment are called intelligent fabrics, such as shape memory clothing fabrics that can restore the initial shape of the fabric by means of external stimulation such as heating, and light-sensitive fabrics that have wrinkle resistance, washability and non ironing functions and can change with the change of light, 1t is mainly used in the military and maritime fields. 1t can change with the temperature of the external environment. 1t is mainly used in the military stealth and large temperature difference environment. 1t can prevent the seawater from penetrating into the clothing. 1t also has high permeability and water absorption

functional fibers can be divided into the following categories


PTT polymer

Corterra fiber made of poly (propylene terephthalate) (PTT) fiber is known as the “elastic fiber of the future”, which has the characteristics of inherent comfort, softness, fluffy, easy dyeing, bright color and durability, 1t is mainly used in heavy or shirt woven fabrics and knitted underwear


moisture absorption and quick drying cool polyester fiber – through physical and chemical modification of polyester fiber, the moisture absorption of polyester fabric can be improved, the surface static electricity can be reduced, and the wearing comfort can be improved

hygroscopic and quick drying cool fibers and fabrics have the following characteristics: A. sweat absorption and quick drying comfort; b. The fabric is light and high-grade, with excellent capillary wicking and dry handle; c. 1t is cool to wear in hot and humid environment in summer; d. Easy to wash, quick dry, no iron

at present, moisture absorbent and sweat wicking polyester fabrics are mainly used in sportswear, casual wear, underwear, coat, socks, gloves, bra, knee protection, hat, towel, etc


high temperature resistant and flame retardant fiber

carbon fiber and aramid fiber with high performance. Carbon fiber is resistant to high temperature, corrosion and radiation. 1t is widely used in aviation equipment and construction engineering. Aramid fiber is high temperature resistant, flame retardant and high toughness. 1t can be made into various protective clothing, fire-fighting clothing and bulletproof clothing. Flame retardant polyester fiber has flame retardant properties because of the phosphorus atom in polyester molecule. 1t is mainly used in hospital, insurance, decorative and industrial fabrics; Flame retardant polypropylene fiber obtains flame retardant property by traditional process treatment or adding additives into polymer formulation. The product is mainly used for curtain, wall cloth and decorative cloth; Melamine fiber is a new type of high temperature resistant fiber with high flexibility and flame retardancy, which can be used in the field of fire protection

with the rapid increase of the consumption of various civil and industrial textiles, especially the increasing demand of various interior decoration, cabin decoration fabrics (curtains, curtains, wall cloth, carpets, furniture cloth, etc.) and bedding, the fire caused by textiles is also increasing. According to the regulations of international organization for standardization, flame retardancy (or flame resistance) refers to the characteristics of materials to slow down, terminate or prevent flaming combustion


antibacterial fiber

by adding antibacterial masterbatch to the chemical fiber, the fabric can obtain antibacterial, deodorizing, anti mildew, anti mite, self-cleaning and other functions. The most famous inorganic antibacterial fiber is nano copper, which has broad-spectrum antibacterial and good thermal stability. 1t is mainly used in underwear, sanitary materials and bedclothes

production method: CO blended spinning process – antibacterial fiber is made by adding copper antibacterial masterbatch in the polymerization stage of fiber production or spinning melt. The advantage of this method is that there is no need for finishing and the cost is low; Long term efficacy, washability and environmental protection. Permanent antibacterial fabric is widely used in hospital, hotel and family bed sheet, quilt cover, blanket, napkin, towel, shoe lining, cloth, curtain cloth, medical professional clothing, work clothes of food and service industry, military clothing, bandage and gauze, etc., which has great social significance


anti mite fiber

mites are very harmful to human health, can spread viruses and bacteria, and can cause hemorrhagic fever, dermatitis, folliculitis, scabies and other diseases. There are three ways to achieve the effect of anti mite: one is not to let mites reproduce, such as acaricidal method, trapping method; Second, keep mites away, such as repellent method; Third, do not let mites invade, such as blocking method

the production methods of permanent anti mite fabrics include functional fiber method and high density fabric method. Functional fiber method: add the anti mite masterbatch to the spinning melt to make anti mite fiber after spinning; Long term efficacy, washability and environmental protection. High density fabric method – the high-density fabric itself is woven tightly or has microporous structure to prevent mites from invading or penetrating the fabric, but it can not avoid or kill mites< Production method: anti mosquito textiles are made of microcapsules containing various mosquito repellent materials and insecticidal materials, which are added into the spinning solution to make the microcapsules combine with the fibers and distribute evenly on the inner surface of the fibers. The fiber can emit the odor that mosquitoes and flies hate, so that mosquitoes and flies do not want to stay on the fabric containing anti mosquito fiber and escape. At the same time, mosquitoes and flies will be knocked down or killed as soon as they touch the fabric. Microcapsule contains natural plant essence and is harmless to human body. Br / >

antistatic fiber

by modifying synthetic fiber, that is, adding antistatic agent or introducing a third monomer into the polymer, the fiber itself has antistatic ability. The products are mainly used for carpets, curtains, hospital operating room work clothes and anti fouling and anti sticking civil textiles

in the contact and friction of antistatic textiles, all kinds of textiles have static electricity phenomenon, but different fibers show different static electricity phenomenon. Natural fibers such as cotton and wool almost do not feel the spot phenomenon in processing and wearing, while synthetic fibers such as polyester and acrylic fiber show strong electrification phenomenon in wearing. 1n the pursuit of environmental protection, ecological, healthy and comfortable textiles, a variety of antistatic textiles came into being


far infrared textiles

in the process of fiber production, far infrared textiles are materials that can absorb external energy (including sunlight and human body heat) and emit far infrared efficiently. They are made into fibers by co blending spinning method and co spinning method, so that the fabric has higher far infrared emissivity in the wavelength range of 4 ~ 20 microns. Far infrared fiber has thermal effect, which can be divided into two types: warm type and health type. Thermal insulation type belongs to thermal storage fiber, which is mainly used for products requiring thermal insulation function; Health care type is mainly to enhance circulation function. At present, there are far-infrared polyester, far-infrared polypropylene, far-infrared nylon, far-infrared acrylic, far-infrared viscose fiber and other products

far infrared health care fabric can be used to develop health care heat storage products, medical supplies, such as underwear, close fitting warm clothing and bedding such as bedspread, sheet, blanket, cushion, knee protection, belt, health care shoes and socks, electric heating products, etc

far infrared fiber is made by fusing ceramic powder with polyester, polypropylene, viscose and other synthetic fibers before spinning. 1t can convert the absorbed solar energy into heat energy needed by human body, promote blood circulation, increase blood and oxygen supply of human body, speed up metabolism and improve muscle energy of human body. The products are mainly used in the fields of medical treatment and health care.


anti ultraviolet fiber

the anti ultraviolet fiber is made by melt spinning of UV shielding agent, which has more than 92% UV shielding rate and certain shielding effect on thermal radiation. 1t is mainly used for making summer shirts, T-shirts and umbrellas


magnetic health care textiles

human cells are micro bodies with certain magnetism, and human body has biological magnetic field. Therefore, the external magnetic field affects the physiological activities of the human body, through the changes of charge, potential, molecular structure, biochemical and physiological functions of the nervous and body fluid system, in order to adjust the body function and improve the disease resistance ability of the human body

magnetic health care textiles mainly use woven and knitted fabrics made of magnetic functional fibers, which are used in various styles of health care clothing and health care products. According to the feedback information of the current users, the magnetic textiles have the characteristics of remarkable effect, strong physical therapy, comfort, softness, easy washing and cleaning


environment friendly fiber

(1) the biggest advantage of cotton is spinnability. Natural bending makes the cotton fiber have a certain strength, which is conducive to the spinning process. Cotton fiber has good hygroscopicity and certain wear resistance, and its moisture regain reaches 8%. 1t has no static electricity, good moisture absorption and perspiration, good air permeability, and is close to human body. The clothes made of it are comfortable to wear, no pilling phenomenon, and soft to handle. The natural waist shaped hollow structure determines the excellent thermal insulation. Cotton has excellent dyeing performance and is easy to dye. Blended with functional fiber, it is the best match. Natural colored cotton, wool and rabbit hair. By changing cotton gene and improving sheep and rabbit breeds, natural color raw materials are formed. Because they are not corroded by dyes and auxiliaries, environmental pollution and harm to human body can be reduced< (2) hemp fiber. Flax, ramie, jute and other hemp fibers have natural antibacterial properties
