Viscose how much you know?

  If someone says that the Miss World finalists most critical step, because wearing a stick-fiber clothing, you can not simply dismiss this argument, sticky fibers is entirely possible the dream of success dudes and babes. Now the market for high fashion, trend clothing, almost all of the above festooning the label marked sticky fiber content. So, what is the sticky fibers? It is what good characteristics? Viscous fiber what health effects on consumers? Meet people from the pursuit of comfort in dress have anything special? Why stick with the clothing fiber value for money? Let us conduct a scientific perspective-depth understanding.
  First, what is the sticky fibers?
  Viscose fiber is the fiber of the full name of the stick.
  Viscous fiber is one of the old fiber varieties. In 1891, the British Cross (Cross), Bevan (Bevan) and Beadle (Beadle), etc. First of all, made of cotton as the raw material of cellulose sodium yellow, due to the viscosity of such a great solution, so named as "glue." Viscose case of acid, the cellulose will be re-precipitation.
According to this principle, in 1893, developed as a method of manufacture of cellulose fibers, the fibers called "viscose fiber." To 1905, Germany Ms. Miller (Muller) and so invented a dilute sulfuric acid and sulfate composition of coagulation bath, to achieve the industrial production of viscose fiber stick, also known as artificial silk, ice yarn, viscose filament. In recent years, there has also called Tencel, bamboo fiber of new varieties.
  In cotton, silk and other 12 kinds of major textile fibers, sticky fibers moisture content most physical demands of human skin, it has smooth, cool, breathable, antistatic, stain beautifully and other characteristics.
  Viscous fiber performance and the nature of natural cotton fiber is very similar to the current, widely used in viscose silk, weaving, knitting, weaving and manufacturing line, the system cashmere industry, can separate into a beautiful silk weaving, spinning and various Fuchun silk quilt cover, etc., but also with wool, hemp, silk and other fibers for weaving, but also with cotton, silk, synthetic fiber woven into camlet, satin and crepe and so fragrant. Because of its comfortable, especially for
  Production of underwear. China's chemical fiber products viscous fiber is the most important competitive fiber varieties.

  Viscous fibers mainly cotton or wood cellulose fiber as raw fiber, its most important feature is certain to take the natural properties of cotton fiber is very similar, such as moisture, breathable, easy to dye, antistatic and easy to spin and other properties. However, a more viscous fiber nature of natural cotton fiber is more pure. Viscous fiber cellulose content of 99.5%, while 95-97% cotton fibers; sticky wax fat and fiber accounts for 0.2-0.3%, cotton fiber accounts for 0.5-0.6%; sticky substance containing chlorine-free fiber, cotton fiber accounted for 1-1.1% of Chlorinated substances; sticky fiber pectin and a number of non-shrink Xu sugar, and cotton fiber with 1.2%; sticky fiber content of other trace ash, cotton fiber content of 1.14% ash.
  Viscous fiber sunlight resistant, anti-insects, heat resistance, chemical resistance, melting agents, anti-mold, in the main textile fiber, it's excellent performance is more comprehensive. Therefore, the viscous fiber has "the essence of cotton, silk quality", is typical of ecological fiber. It comes from natural and better than natural.
  Third, why the most viscous fiber skin moisture content of the physical needs?
Some experts in the "man-made fibers," the author said: human skin surface water at 12-15%, the skin smooth and elastic. Once dry skin becomes dry, followed by coarse dry, for a long time the wrinkles will appear.
   シャネル コピー グッチ コピーTherefore, the requirement to have a certain textile moisture absorption, air permeability, moisture regain of fiber to ensure that 12-14% of skin surface moisture content of 12-15%. Balance of the major textile fibers regain the standard are:
  Cotton 7-8.5%, 14-16% wool, silk 9-11%, 12-14% adhesive fiber, polypropylene and polyvinyl chloride fiber is 0, 0.4-1.3% spandex, polyester was 0.4-0.5%, 7.0-10.0% ramie and so on.
  Thus, the most viscous fibers regain skin moisture requirements. In warm weather, breathable, absorbent; cold weather can be moist, not static, soft and comfortable, specially designed to meet physical needs of human skin. The main characteristics of viscous fibers because it contains a lot of hydrophilic groups [- hydroxyl (-OH)], cellulose large number of molecules adsorbed water molecules and hydration play a role, while the crystallization of viscous fiber ratio
  Other textile fibers determined by the characteristics of the low. They also made a scientific thesis, even if the cotton and viscose rayon underwear underwear is not consistent with human skin moisture requirements. The wool fiber was slightly higher than the skin surface of the water content of 12-15%, although the heat, but easy to static electricity, from this point and is not sticky fiber.
  As the viscous fiber has to make the most moist skin has been in a state of the properties, therefore, been widely used for underwear, pajamas, T-shirts, shirts, also for the cheongsam, the Tang suit, etc. made.
Fourth, 韓国ドラマ dvd 激安 激安 dvd 中国what clothing and electrostatic hazards on people? Viscous fiber antistatic performance?
  Winter air is too dry, skin and clothing easily between the static and high static pressure up to those moments of thousands of volts, will cause damage to the human body. It was done on the daily life of a static survey and measurement, walking on the carpet can generate static electricity 1500 to 35,000 volts, the vinyl resin produced when walking on the floor 250 to 12,000 volts static electricity, indoor chair Yiceng will result in 1800
  Volts or more static. Depending on the level of static ambient air humidity. Electrostatic interference is usually more than 7,000 volts, people will have a sense of shock.
  Information that the human body has a very large electrostatic hazards. Long-lasting alkaline static can increase the blood, reducing serum calcium, urinary calcium excretion increased, and this is the growth and development of children, the elderly low blood calcium levels, and many pregnant women take calcium and lactating mothers and children is undoubtedly worse. Excessive accumulation of static electricity in the body, but also lead to brain cell electrical spread
Conductivity anomalies, central nervous, leading to blood pH and oxygen characteristics of the body affected by changes in the body's physiological balance, people dizziness, headache, irritability, insomnia, poor appetite, trance and other symptoms.
 日本映画 Static electricity can interfere with human blood circulation, immune and nervous systems, affecting all organs (especially the heart) is working properly, may cause abnormal heart rate and heart premature. In the winter, about one-third of cardiovascular diseases and related static. In explosive areas, the human body with static electricity may even cause a fire.
  Recently, the Japanese MITI damage to clothing to the skin up to the security issue to understand. A survey showed that 600 out of 1,500 people have strange feeling of cloth damage to the skin. Nylon, polyester, polyacrylonitrile fibers and acetate fibers made fiber underwear close, there is the prominent problems caused by skin inflammation. They tracked the patients heart premature observation, some patients found no structural heart disease, and no smoking, alcohol, medication, etc., causing arrhythmia. They have in common is to wear synthetic clothing.
Synthetic fiber clothing and the skin caused by friction between the static, static electricity voltage of more than 4,000 volts in an instant, changed the surface electrostatic potential difference, impeding the normal cardiac conduction. So-induced premature ventricular contractions and other arrhythmias. When the recommendations of these people wearing other fiber underwear, the arrhythmia would miraculously disappear. Synthetic clothing can be obtained through the conclusion of arrhythmia, it is not alarmist.
   新作映画 人気アニメThis shows that the elimination of the human body with static electricity, the most important one should not wear synthetic underwear, synthetic fiber fabric does not make contact with the skin. Resistance from the fiber of view, should wear viscose fibers, cotton and hemp.
  However, the use of hemp fiber can be made to wear underwear in summer, to the other seasons is clearly not comfortable. Therefore, more usually wear cotton, but cotton fiber and viscose fiber containing wet far, and viscose fiber flexibility is also better than the cotton fiber.
  Therefore, moisture from the skin and wearing soft and comfortable, and the fiber resistance of view, the scientific concept of health is to choose to wear the consumption of viscose fiber, fabric made of viscose fiber underwear is the most appropriate.
  Can be seen from the following list, static, and wearing clothing which the fiber has a very close relationship.
  Fiber types of volume resistivity (Ω · cm)
  107 of 107 viscose cotton wool and nylon 109, acetate fiber 1012 (to oil) 1012 acrylic (to oil) 1014 Polyester (to oil) 1014 chlorofibres 1015
  Can be seen from the table, the resistance of cotton and viscose fibers lowest, while the resistance of synthetic fiber is much higher.
  Five, why stick fiber clothing will be very unique smooth feel?
  Viscous fiber is cotton fiber and other natural fiber cellulose purification, and continuous pumping made of cellulose fibers. Viscous fiber in the production process determines its longer than cotton and other fiber properties, and excellent adhesive properties of fiber moisture, has a superior anti-static properties, does not produce the feeling attached to the body, single fiber structure, the proportion of higher than cotton, which drape and is very smooth, which is other fiber
Victoria can not match.
  Sixth, why stick the dyeing properties of fibers are 10 kinds of major textile fibers in the best?
  Viscous fiber of this feature to meet the needs of people seeking international fashion color. Both dyeing and finishing of the physical treatment and chemical treatment, or bleaching, dyeing, printing and finishing, all kinds of fiber dyes are suitable for viscous fiber, following the application of various fiber dye table:
Project cotton polyester viscose nylon wool
  Direct dye application, reduction,
  Alkaline, sulfide, reactive, azo, mordant acid, reduction, direct, mordant dyeing, indigo type, alkalinity, dissolved chromium, active direct, reduction, basic, color phenol, sulfide, reactive, mordant, azo disperse, color phenol, reduction, soluble disperse, acid, chromium media
  Project chloride fiber spandex polypropylene acrylic PVA
  Application of dye dispersion, alkaline, acid, cationic direct, acid, sulfide, reduction, color phenol, distributed dispersion, acid,
  Chelated liquid dispersion, color phenol, metal dispersion, acidic, alkaline, metal, chrome media
  As can be seen from the table for viscose dye up, not only more than the synthetic fibers, the same than with its chemical composition of cotton (both formed by the condensation of many glucose molecules) has more. It is reported that viscous fiber has been able to cool in the thousands of bright colors. In more than 500 times magnification under the microscope, we can see that the single sticky silk fiber surface has many irregular grooves, there are many non-crystalline regions, these micro-structure will help absorb dye and fixation, thus, In contrast, viscous fibers stained clothing is not only beautiful, but, not easy to fade color fastness.
  7, adhesive fiber excellent moisture absorption and staining its performance and cost matter?
  Viscous fiber of moisture absorption and staining properties and fiber itself contains a large number of hydroxyl (-OH) has a close relationship, hydroxyl (-OH) groups in a large number of adsorbed water molecules or other molecules, the better moisture absorption of fiber dyeing, the better. Viscose fiber manufacturing process as it has gone through many physical and chemical reaction caused by decomposition of cellulose macromolecules groups, to shorter molecules, molecular gap large sparse arrangement also
  Song messy, the hydroxyl molecule (-OH) may be polar, nor in these superior than cotton. Therefore, cotton viscose fiber dyeing better than some, not only for many dyes, chromatography wide stain color is also bright.
  Which belong to the regeneration of cellulose acetate fibers in fiber (including the two acetate fibers and three acetate fibers), and their dyeing performance was significantly inferior to viscose fiber. This is because the molecules of acetate fibers most of hydroxyl (-OH) was acetylated became a hydrophobic group. Therefore, viscose and cotton can be used to dye it can not necessarily be. Can be seen in the cellulose fiber, rayon fiber dyeing is the best, but also easy to dye, and the cost of printing and dyeing and lower.
  Viscose fiber in printing and dyeing, also has shortcomings, such as cotton, cellulose fiber it can be widely used as dyes. Although reactive dyes can replace a number of harmful chemical dyes, but it is in the dyeing process of the formation of more colored water. In addition, in some printing and dyeing viscose rayon color fastness and light performance is less than some of the synthetic fiber. Although this and related dyes and process, but the ease of dyeing viscose fibers, chromatography full, bright color, low cost, is nonetheless a great advantage.
  8, viscous fibers which functional fiber?
  Viscose fibers including ordinary fiber, high wet modulus fiber, glass fiber, modified and several categories of special fiber.
  Ordinary fiber include: viscose rayon filament and staple fiber, staple fiber, it also includes: cotton-type fiber, wool fiber,
  Mid-fiber and high crimp fiber; high wet modulus fiber include: polynosic fiber, high wet modulus fibers,
  High crimp and high wet modulus fiber; strength fiber include: general strength fiber, ultra-strong fiber; Modified
  Special fiber include: graft fiber, flame-retardant fiber, hollow fiber, conductive fiber, anti-bacterial fiber, colored fiber.
  Viscous fiber products to achieve differentiation and its function, in addition to conventional products, but also the development of the fine denier fiber, superfine fiber, profiled fiber, coarse denier fiber, very crude fiber, crude monofilament fiber thin filaments, monofilament thick filaments are not crude fiber, composite fiber degeneration savings fiber, fiber matting agents, coloring agents and other fibers modified with various functional materials, such as flame retardant, antistatic, anti-odor, antibacterial, high moisture absorption, anti- Ultraviolet radiation and functional fiber.
  9, viscous fibers are green products?
  In addition to natural fibers such as cotton, wool, green fiber, Lyocell fiber is the green fibers.
  1, from the view of the molecular structure of viscous fiber
Green fiber, cotton, linen and wool is a natural molecular structure of cellulose, basically (C6H10O5) macromolecules, degree of polymerization above 200, called the α-cellulose. Again, this is the main component of viscose fiber, the difference is that they contain a large number of macromolecules on hydroxy (-OH) hydrophilic group.
  Another is the different molecular structure: macromolecular crystallization cotton 70%, while the crystallinity of viscose fiber is only 30 ~ 40%, about 44% Modal fiber, fiber is only 48% polynosic , Lyocell fiber is about 50%.
Wool is a natural protein polymer, is the formation of α-amino acid peptide composed of more than. In its molecule that contains a large number of (-CONH-) amide, (-NH2)-amino-Hop (-COOH) carboxyl groups, which are hydrophilic groups.
Water, natural protein and cellulose are major components of life on Earth. The fibers are natural cellulose, the basis of the natural protein but also has a large number of hydrophilic groups, and therefore life on Earth has a natural affinity, thus more human kinship. Although the regeneration of cellulose viscose rayon fiber, but fiber is still the natural macromolecular molecules, it Lyocell fibers belong to the same
  Class molecules, so when cotton, hemp, wool, and Lyocell fibers are seen as green fibers, viscose fibers when used as a textile fiber of course, the green fibers.     
  2, from analysis of fiber production
  Consumption of green products and green ideas from Germany in 1997 introduced the "Blue Angel Plan", which mainly manufacture and production of products to meet environmental requirements, to the factors that will minimize negative environmental protection. Was first launched in Europe on textile Oeko-Tex100 environmental standards, the formation of green textile entry certification mark. In 2002 the world's largest enterprise cellulose fibers Lenzing, Austria was granted all the company's products and EU-eco logo, the logo of the assessment is very rigorous and relevant products and processes to go through the process of analysis and testing. China Siliya viscose fiber and some good company's products have been Oeko-Tex100 logo. This shows that the viscose fiber is the green product categories.
  3, from the comfort of the human body
  The most moisture content of viscose fiber to satisfy the requirements of human skin against moisture, while the conductivity of its natural fibers are better than others, these show viscose fiber more than other human health requirements.
  Because viscose fibers good moisture absorption and softness, it is processed into a wide range of spunlace non-woven fabrics for the health sector and various one-off clean with a cloth.
  4, from the softness of garment
  Soft viscose fiber is good. At present, the pursuit of dress is more casual, more comfortable and has become a trend. One of the underwear of the softness is an important one. Some countries also provide baby clothing and bedding banned synthetic fabric, in order to protect the skin and use of more comfortable. Currently, Japan, EU and other developed countries have strict requirements on the baby clothing must comply with the International Textile Standard Oko-Tex100, in our country will have to comply with the standards of ecological textiles HJB30-2000. Clothing for babies are generally simple, warm, soft as the main principle. The viscose fiber flexibility is better than cotton and Lyocell and other chemical fiber.
  5, from the waste pollution analysis
  Viscous element is carbon fiber (C), hydrogen (H), oxygen (O) consisting of its waste in nature under the action of sunlight and water, until the decomposition of cellulose will slow degradation, without any harm to people and nature.
Viscose and Lyocell fibers, like cotton and are derived from natural cellulose, biodegradable waste after use, it is a natural cycle characteristics, the basic will not cause environmental pollution. The synthetic polymer is artificial, difficult to degrade after disposal will cause white pollution.
