Introduction of bamboo fiber series
A series of bamboo fiber as raw material according to the different processing methods, the current can be divided into: --- original bamboo fiber bamboo fiber; --- regenerated bamboo fiber bamboo fiber; bamboo charcoal fiber. Usually we have mentioned most of the bamboo fiber is regenerated bamboo fiber products as raw materials.
Bamboo fiber is a unique process directly isolated from bamboo fiber, by the experts as the "breathing the fibers."
Bamboo fiber is made into pulp by chemical methods obtained after the spinning. Hebei Jigao production of "bamboo" fiber is a bamboo fiber, which consists of cotton, in the long type, hair type composition, fiber products, uniform, length uniformity, spinning performance, but also according to customer specifications, production of special yarn line. "Bamboo" fiber textile fabric soft, comfortable and smooth, there is a sense of velvet, wearing a light next to the skin. "Bamboo," a special hollow fiber structure, can absorb and evaporate moisture in an instant, it has the cool of taking performance, suitable for making clothing, home textiles, interior decoration and so on.
Bamboo fiber is the use of nanotechnology, the first powder of bamboo charcoal, bamboo charcoal powder and then through the high-tech nano-processing technology, and then prepared using the traditional chemical process, can be spinning molding, bamboo charcoal fiber prepared qualified. Currently, bamboo fiber fabric has received applications, and in the market, won the "black diamonds" in the world. The picture shows the "bamboo" fiber products
The characteristics of bamboo fiber bamboo viscose fiber made of bamboo as raw material, it is a new type of green viscose fibers, the fibers woven into the fabric has antibacterial, deodorant and other special features.
Bamboo fiber is a fiber registered Hebei Jigao the "bamboo" brand bamboo viscose staple fiber, it is a new natural, green, green fiber, which uses rich land of abundance of bamboo in China for raw materials, through to treatment and two sulfate cooking Second drafting meeting and other special acid bath, complex treatment process, the ratio of 8:1, the extracted cellulose Takeuchi, and then by spinning processes made of. The fiber fineness and whiteness of the close of ordinary viscose fiber, strength is good, toughness and wear resistance high, excellent spinnability, made of breathable fabric and excellent moisture absorption, with a smooth, velvet, anti-bacterial, odor and other special features. Because of its natural anti-bacterial and deodorant function, so that bamboo fiber underwear products in the health material and has a unique charm.
Breaking strength of dry bamboo viscose fiber in 2.7-3.OcN/dtex, wet breaking strength 1.3-1.5cN/dtex, better than the cotton fiber, process the following points have been adjusted.
(1) to ensure control of bamboo pulp degree of polymerization of 600-700.
(2) in the viscose denaturant added to extend their shape, so that the fibers in the first high-power tensile acid bath, acid bath in the second draft of up to 1.6
(3) Road to hot drawing from the Ⅰ Ⅱ Road, after Ⅱ Road, led after the heat, humidity control mode coefficients between 1.2-1.4.
Because the nature and processing of bamboo is different from bamboo fiber caused some of the features is different from other fibers.
1. Has good moisture absorption, air permeability
Fiber moisture absorption and polymer functional groups and the structure of natural cellulose and regenerated cellulose although the same number of hydroxyl groups, but because fewer hydrogen bonds between molecules of regenerated cellulose, so it's bigger than natural fibers and moisture, Bamboo fiber is a regenerated cellulose fiber, the structure of porous network structure, moisture permeability of its viscose fiber is better than the other, giving a feeling of cool sweat.
2. Higher initial modulus, anti-pilling and wrinkle resistant
Initial modulus fibers can be used to show that the rigidity, the initial modulus value depends on the chemical properties of polymers and macromolecular interaction between the intensity of the soft, supple macromolecular chains of larger, then the fibers more easily deformation, Preparation of a polymer fiber with an initial modulus greater the intensity of the molecular interaction between the larger fiber crystallinity and orientation degree, the greater, bamboo fiber crystallinity of 40%, while viscose fiber crystallinity of 30%
3. Natural antibacterial, antimicrobial and UV resistance
Bamboo in the growth process, no insects bore no no corrosion, very good in the nature of self-protection, if there are other plants asphalt Cupressaceae trees, aloe, licorice, cloves, indicating that its natural antibacterial bamboo and antibacterial substances, and resistant to pests and diseases outside world, this kind of material in small amounts in the bamboo, we call it "bamboo quinone" in the production process using patented technology, to remain in the bamboo fibers from damage so that it has antibacterial and antimicrobial activity, and by Japan Textile Inspection Association confirmed, has good antimicrobial activity, to prevent the breeding of bacteria, cut off the route of transmission through clothes, but by the Shanghai Institute of Physics, Chinese Academy of Sciences testing proved that bamboo fiber fabric on the 200-400nm UV transmittance is almost zero, we can see that bamboo fiber fabric has a good shielding effect against ultraviolet rays, thus ensuring the human body from UV rays, especially the atmospheric ozone hole growing, more and more by the ultraviolet, more serious damage on the human body, the special nature of bamboo fiber to ensure the health of the human body, even more significant. Wood fiber in 20-30 ℃, pH4.7-7 and the water close to or above the fiber saturation point, serious decay by the fungus into the role of powder, cellulose degradation seriously, and bamboo fiber trace elements because it contains anti-bacterial, in the growing season, and kept no insects, no termite, no decay phenomenon, that bamboo has natural antibacterial own, bamboo fiber in the purification process using new technology to make anti-bacterial substances adsorbed on the molecular chain is not damaged, and other fibers in the post-processing by adding antibacterial agents are essentially different bamboo fiber fabrics after repeated washing the sun will not lose its antibacterial activity, tests by the Japanese Textile Inspection Association; same number of bacteria under a microscope, in cotton, wood survive and multiply on the fiber fabric, bamboo fiber products, not only can not long survive, but also in the short-term reduction, antibacterial bamboo fiber is a unique feature. Bamboo in the growth process, and insect, does not need to spraying; because bamboo can reproduce itself, does not need to fertilization;
Bamboo fiber has a porous network structure, you can Shunshi swelling in water, so that excellent water-soluble reactive dyes which dye, molecular and small bamboo quickly adsorbed on the fiber, and can quickly spread in the bamboo fiber, initial dye higher rate of half dyeing time is shorter, because bamboo fiber reactive dyes in the higher diffusion rate, but also give it a good permeability and levelness, the structural features, reactive dyes can increase the absorption area, reactive dyes and to hydrogen bonding between the bamboo fiber, multi-layer van der Waals forces to form the absolute increase in the number of physical adsorption, so the balance of a higher percentage of dye uptake, the high percentage of the dye under the premise of participation with the occurrence of bamboo fiber bonding reaction of reactive dyes increased, given the high fixation rate, therefore, bamboo fiber reactive dyes, excellent performance, a higher percentage of its equilibrium dyeing, half dyeing time is short, bright color, good dyeing, fixing rate, fastness excellent.
5. No acid and alkali resistance
In the cellulose macromolecule, the basic chain linking the glucoside bond, the acid stability is very small, in addition to structural characteristics of bamboo fiber, the stability of the inorganic acid is smaller than the viscose fiber, the temperature rises, the damage acid particularly strong effect, bamboo fiber swelling in alkali and the dissolution of strong base in the same conditions, the permeability of the bamboo fiber is larger than the ordinary viscose fiber, so although the crystallinity of bamboo fiber than ordinary viscose fiber high, but porous structure, resulting in poor alkali resistance.
6. Strong heat resistance
Viscose fiber is a higher heat resistance, and higher than that of cotton, bamboo fiber is better than the heat resistance of viscose fiber.
Under normal temperature conditions, and textile bamboo fiber is very stable, but in a certain environment and conditions, bamboo fiber can be decomposed into carbon dioxide and water, degradation methods are:
(1) waste: cellulose combustion of CO2 and H2O, environmental pollution.
(2) embedded in the degradation of land: soil nutrients to the soil microbial activation, increased soil strength, after 8-10 months of degradation.
(3) degradation of activated sludge: mainly through a large number of bacteria present, the cellulose decomposition.
Introduction nylon; generic polyamide fiber, polyamide produced is referred to the fiber. Internationally known as nylon. High strength. Wear resistance, good elasticity. Can make a variety of pure and blended textile fabrics and knitwear. The main varieties are nylon 6 and nylon 66, and its almost the same physical properties. Moisture absorption than nylon and polyester dyeing good acid and alkali but not long-term exposure to sunlight will decrease the fiber strength. Have heat-setting properties of nylon and can hold the formation of deformation heating.
Can be made of stretch nylon filament yarn, staple fiber blended with cotton and acrylic, to enhance its strength and elasticity. In addition to the application of clothing and accessories, but also widely used in industries such as tire cord, belt, soft tubes, ropes, fishing nets, tires, parachutes and so on.
Nylon Nylon is a synthetic nylon defined the Chinese name, translated name known as "Nylon", "Nylon", scientific name polyamide fibre, the polyamide fiber. Jinzhou Chemical Fiber Factory is the first synthetic polyamide fibre plant, therefore it the name "nylon." It is the world's first synthetic varieties, due to excellent performance, raw materials rich in resources, has been widely used.
The performance of nylon strength, wear resistance, ranking first in all fibers. Its wear resistance is 10 times that of cotton fibers, viscose fibers dry state 10 times, is 140 times of wet fiber. Therefore, their durability is excellent.
Nylon fabric flexibility and elastic recovery excellent, but the small force under the deformation, so the fabric folds in the wear process variable.
Poor ventilation, easy to produce static electricity.
Nylon fabric synthetic fabric moisture is good in the variety, hence the production of clothing than polyester nylon clothing wear comfortable.
Good resistance to termite, corrosion resistance.
Heat lightfastness are not good enough, ironing temperature should be controlled at 140 ℃ or less. In the wearing course should note using the washing, maintenance conditions, so as not to damage the fabric.
Nylon fabric is lightweight fabrics, synthetic fabrics in only out in polypropylene, acrylic fabric, the result, suitable for production of mountaineering and winter clothing.
Nylon nylon many kinds of species categories, there are nylon 6, nylon 66, nylon 11, nylon 610, nylon 66 is the most important and nylon 6. Not identical nature of all kinds of nylon, a common feature on both the main chain amide macromolecular chain, to adsorbed water molecules can form crystal structure, wear resistance and very good fiber clothes are excellent.
Polyamide fiber fabric can be divided into pure spin, blending, and mixed fabrics three categories, each category contains many varieties.
1. Pure nylon textile nylon fiber as raw materials in a variety of woven fabrics such as nylon taffeta, nylon crepe and so on. Silk with nylon for long, so it feel smooth, fastness and durable, affordable features, there are also easy to fold and easy to restore the fabric of the shortcomings. Lightweight nylon taffeta and more used for clothing, down jacket or raincoat fabric, and nylon crepe dress is suitable for summer, spring and dual-use Shandeng.
2. Nylon blended and mixed fabrics with nylon filament or staple fiber blended with other fibers or woven fabrics obtained, both the characteristics and strengths of each fiber. Such as a sticky / Kam gabardine, with 15% nylon and 85% viscose blended yarn obtained, with a warp density twice as large than the weft density, then the body texture of thick, tough and durable features, drawback is poor flexibility, easy crease, wet fall, when the easy to wear sagging. In addition, stick / Kam valitin, sticky / nylon / wool tweed and other varieties, are some common fabric.
The most common market for the nylon 6 and nylon products nylon 66.
Nylon 6: Nylon fiber full name, by the polymerization of caprolactam.
Nylon 66: full name of the acid poly hexamethylene diamine fiber has, by polymerization of adipic acid and hexamethylene diamine.
Nylon 6 and nylon 66 common characteristics: light is poor, in the long daylight and UV irradiation, the intensity decreased, the color yellow; its heat resistance is also not good enough, at 150 ℃, 5 hours that changed through Huang, strength and elongation decreased significantly increased shrinkage. 6,66 nylon filament with a good low temperature performance, below minus 70 ℃, its resilience will not change much. It is the dc conductivity is very low, in the process vulnerable to friction and static electricity, the conductivity increases with the moisture absorption rate, and with the humidity increases by exponential law of increase. 6,66 nylon filament with a strong ability of anti-microbial action, in sludge water or soda behind the ability of microorganisms resistant polyvinyl chloride fiber. In chemical properties, the nylon filament 6,66 alkali resistance and reducing agent with the role, but in the acid resistance and poor performance on the role of oxidant.
Polyurethane spandex fibers are short fibers, trade names are Lai Kela (Lycra, United States, Britain, the Netherlands, Canada, Brazil), Antonio Wong (Neolon, Japan), Dora Stein (Dorlastan, Germany). First of all by the German Bayer Company of success in 1937, DuPont began commercial production in 1959. At present, nearly 40 factories, seven lines of production, the annual output of about 10 million tons, China's current production capacity of l million tons. Spandex is a synthetic, composed of material containing more than 85% of polyurethane components.
There are two varieties of spandex fiber, a double by different neuraminidase aromatic hydroxyl-containing polyester copolymer chain segment mosaic (referred to as polyester polyurethane), and another double by aromatic isocyanate and polymer containing hydroxyl groups ether chains inlaid copolymer (referred to as polyether-based polyurethane). Elastic spandex fiber and polyolefin fiber and elastic fiber elastic fiber collectively.
High elongation (400%), low modulus and high elastic recovery rate of synthetic fibers. Segmented polyurethane fiber of the Chinese trade name. Also known as the elastic fibers. Spandex with high elongation (500% ~ 700%), low elastic modulus (200% elongation, 0.04 to 0.12 g / denier) and high elastic recovery rate (200% elongation, 95% ~ 99%). In addition to greater strength, other physical and mechanical properties very similar to silk and natural latex. More resistant than latex chemical degradation of silk, with a moderate thermal stability, softening temperature above about 200 ℃. Synthetic and natural fibers used for the majority of dyes and finishing agents, but also for dyeing and finishing of polyurethane. Spandex perspiration, water-resistant and resistant to all kinds of dry cleaning and most of the sunscreen. Long-term exposure to sunlight or chlorine bleach will fade, but fade with the level of the different type of spandex, very different.
Spandex fiber with such a high elasticity so because of its low melting point polymer chain is the amorphous "soft" segments for the mother and embedded in one of the high melting point, crystallization of the "hard" segments formed. Flexible chain segments between cross-linked to a certain a certain network structure, the interaction between the molecular chains of small, free expansion, resulting in a large elongation properties. Rigid chain links together large molecules, the molecular chain is not unlimited extension, resulting in high elasticity. Lun filament cross-section of radon most of the dog bone-shaped (dog-bone-shaped) are also some filament surface smooth or serrated. Breaking strength of all the textile fibers is the lowest, only 0.44 ~ 0.88CN/dtex (polyether strength than polyester). Moisture range of smaller, usually 0.3-1.2% (absorption rate of filament slightly higher than the single-wire). Different depending on heat-resistant varieties are quite different, most of the fibers in the range of 90 ~ 150 ℃ kept short, the fiber will not be injured, security ironing temperature is 150 ℃, can interfere with wet heat. Dyeing better performance, can be dyed various colors Dayton, dye fiber affinity, and can be adapted to most varieties of dyes, and has good chemical resistance, resistance to most acids, alkalis, chemicals, organic solvents, dry cleaners and bleach, and resistance to sun and snow, but the impatience oxide, yellow and easy to make the fiber strength decreased.
Spandex is generally not used alone, but mixed with a small amount to the fabric. This fiber has both properties of rubber and the performance of a fiber, mostly for the spandex yarn as the core yarn, called elastic yarn, this yarn, the main characteristics, namely, get a good feel and appearance, composed of natural fibers outside fiber moisture absorption; Second, only 1-10% of the spandex yarn can produce high-quality stretch yarn; third is the percentage of control flexibility from 10% to 20%, according to the use of the product , choose a different elasticity values. Easy-to-25 to 2500 Dan spun silk of different thickness, it is widely used to make elastic fabric, such as socks, furniture covers, ski clothes, sportswear, medical fabric, ribbon, military equipment, spacesuits and other flexible part of the . With new demands on the fabric, such as light weight, comfortable fit, soft, etc., low-denier spandex fabric in the proportion of synthetic fabrics is also growing. Also useful silk and spandex spandex naked combined with other fibers made of twisting twisting wire, mainly used for warp and weft knitted fabric, woven fabric and elastic cloth.
