Differential fiber
The differential treatment of fibers is the need for the development of chemical fibers. With the development of chemical fibers and the textile industry, chemical fiber products are increasingly used in taking and other fields. While people fully appreciate many of the excellent properties of synthetic fibers, there are also some deficiencies in the use of synthetic fibers, especially when taking and decorating. This prompted people to make necessary modifications to chemical fibers, especially synthetic fibers.
Differentiated fibers generally refer to chemical fibers that are physically or chemically modified on the basis of conventional chemical fibers so that their properties are improved to some extent. There are many varieties of differentiated fibers. Here are some commonly used differential fibers.
Shaped fiber
Profiled fibers refer to non-circular cross-sectioned chemical fibers processed with a non-circular orifice spinneret. According to different spinning holes, shaped fibers can be divided into triangular (trilobal, T-shaped), polygonal (five-star, five-leaf, hexagonal, branch-shaped), flat-shaped (dog-bone, bean-shaped) and hollow ( Round hollow, triangular hollow, plum hollow) fiber and so on.
Shaped fibers have a certain effect on improving fabric luster, feel, coverage, breathability, stain resistance, anti-pilling, and elasticity. Such as triangular cross-section of the fiber has the effect of flash; cross-section of the fiber elasticity is good; flat section of the fiber has significantly improved the anti-pilling; shaped fiber used in a variety of imitation silk, wool, imitation linen fabric.
2. Microfiber
The fibers with a monofilament linear density of 0.44 dtex become ultrafine fibers, and the fibers with a linear density of more than 0.44 dtex and less than 1.1 dtex become fine fibers. Microfiber products have high added value, and their fabrics are delicate in touch, soft and light, with good drape, breathability and wearing comfort. Microfibers are mostly used for artificial silks. Imitation peach, imitation suede, imitation down and high-grade filter materials and other high-value and high-tech products.
3. Composite fiber
Composite fibers, also known as conjugate fibers, refer to fibers that have two or more non-mixed polymers present in the cross-section of the fiber. The composite fibers are classified into two-component composite fibers and multi-component composite fibers according to the contained components. The composite fibers can be classified into side-by-side, skin-core, sea-island, and radial, depending on the distribution of the components in the fibers.
Due to the difference in the polymer properties of the components constituting the composite fiber, the composite fiber has many excellent properties. If the use of different components of different shrinkage, the formation of a stable three-dimensional three-dimensional crimp fibers. This kind of fiber has good fluffiness and good elasticity for spinning. The advantages of good cohesion between fibers, the product has a certain degree of hair type. Another example is the use of nylon for the skin, polyester fiber as the core of the composite fiber, both the dyeing of nylon, the advantages of good wear resistance, but also high polyester modulus, good elasticity. In addition, composite fibers with flame retardant, electrical conductivity and other functions can also be produced through different composite processing.
4. Easy to dye fiber
Easy-to-stain fibers can also be referred to as differentially dyeable fibers (DDF). The so-called "easy-to-dye" fiber means that it can be dyed with different types of dyes, and the dyeing conditions are mild, the chromatography is complete, the color is uniform and the fastness is good. The common varieties are mainly cationic dyeable polyester fiber (CDP), normal temperature atmospheric pressure cationic dyeable polyester fiber (ECDP), acid dyeable polyester fiber, acidic or basic dyeable polyester fiber, acid dye Dyed acrylonitrile fiber, dark acidic dyeable polyamide fiber, and cationic dyeable polyamide fiber.
Difunctional fibers
Functional fibers are fibers that have a specific function in addition to their original properties. Analyzed from the consumer market, functional fibers are mainly composed of three types: comfort, health care and protection. Among them, the comfort type is the most basic requirement for fabrics, such as moisture absorption, moisture permeability, lightness, softness, and cold and warmth; basic functions such as antibacterial, deodorizing, skin care, anti-pollution, etc., and protection against UV and antistatic. Radiation protection, anti-virus, flame retardant and other functions. The method of developing functional textile fibers can be roughly divided into two types: one is the functionalization of fibers; the other is the functionalization of finishing, that is, some functions are obtained by processing methods such as padding and coating.
Flame retardant fiber
Fibers that meet the specific combustion test criteria that are stipulated in certain application areas are called flame-retardant fibers. It is mainly used again in the event of a fire hazard or in a hazardous situation in the event of a fire. For example, the United States, the United Kingdom, Japan, and other countries have restricted the application of non-flame-retardant fabrics in certain legal forms, that is, require the decoration of public buildings such as hotels and theaters, elderly clothing, handicapped clothing, mattresses, and other fabrics. Textile fabrics must meet certain flame retardant standards. At present, flame retardant materials mainly develop flame retardant polyester, flame retardant acrylic, flame retardant polypropylene, flame retardant viscose fiber and products. At the same time, it also finishes fire-retardant finishing on cotton, viscose, wool and even polyester fabrics. In addition to the above-mentioned fields, product uses can also be used to make fire fighting clothing, military clothing, industrial protective clothing, and protective underwear.
2. Antistatic fiber
Antistatic fibers refer to fibers that do not tend to accumulate static charges. Under standard conditions, the quality coin resistance is less than 101oΩ·cm. Anti-static fiber fabrics are commonly used in explosion-proof, dust-proof workwear.
3. Warm temperature control fiber
1 High Hollow Fiber: High hollow fiber is made by spinning with a soluble polymer and then dissolving the core soluble component. The hollowness can reach 35% ~ 40%. Compared with solid fabrics, it has high warmth and light weight of 60% ~ 70%. With warmth, light weight, washability, warmth can be comparable to down.
2 Trimune Crimped Fibers: Tri-folded crimped fibers are formed by the use of different shrinkage properties between the two components of the composite fiber. This curl has three-dimensional, long-lasting stability, good elasticity and other characteristics, so that the fabric's fluffy, better coverage. Can be used as a down substitute, used as a ski wear, bedding, pillows, toys, chair cushions and so on.
3 Far-infrared fiber: Far-infrared fiber is made of ceramic powder that can emit far-infrared rays as an additive and is produced by blending and spinning. This fiber absorbs the heat of the surrounding environment and emits far-infrared rays to the human body at the same time. In addition, there are various functions such as absorbing sunlight, converting light energy into heat energy, and preventing far-infrared heat generation from the human body. After being absorbed by the human body, far-infrared fiber can make people feel warmer. Colleagues can speed up the metabolism of the human body in the new city, promote blood circulation, and have dual functions of warmth and health. Can be used as electric blanket cover, sportswear, winter clothes, thermal underwear and so on. Treatment of hypertension, diabetes, rheumatism, low back pain, frozen shoulder, etc.
4. High hygroscopic fiber
Compared with natural fibers, most synthetic fibers have poor hygroscopicity, especially polyester and polypropylene, and thus seriously affect the wearing comfort and hygiene of these fiber fabrics. Colleagues, poor fiber hygroscopicity also brings a series of problems such as static electricity, poor stain resistance. To improve the hygroscopicity and comfort of synthetic fibers, chemical modification methods and physical modification methods can be adopted. The modification can improve the wetting and swelling capacity of the fibers, or can be made into porous microfibers to form microcavity systems inside. Reinforces the ability of the fiber to absorb (absorb) water from air or water. Hygroscopicity modified fiber is mainly used for functional underwear, sportswear, training wear, sports socks and other products.
5. Hygroscopic fiber
Moisture wicking fiber has a unique "cross" shape, "five-leaf" shape and other profiled cross-section. The fiber has a strong moisture absorption and quick drying performance, thus forming a comfortable and dry "microclimate" between the human body and the fabric. Its moisture climb height, diffusion speed, diffusion time and evaporation rate are much higher than ordinary fabrics. The fabric is breathable, hygroscopic, quick-drying, comfortable, clean, soft and smooth, and is an excellent fabric for sportswear, casual wear and shirts.
6. Antibacterial and deodorant fiber
Antibacterial and deodorant fibers are prepared by adding inorganic bactericidal additives such as antibacterial stones to the polymer. Stone boiling is harmless to the human body, but it is effective against various bacteria and molds such as Klebsiella pneumoniae and Pseudomonas aeruginosa, and it is particularly good against Staphylococcus aureus (MRSA). MRSA is the culprit in the hospital causing patients to cross-infection. Hospitals made from antibacterial and deodorant fibers have good development prospects.
