Soybean Fiber - The current chemical name is: Soybean protein fiber. Soybean fiber content of 16-50% soy protein polyvinyl alcohol, only two major components through grafting, copolymerization, blending the production of fiber, as the soybean fiber. Soybean fiber was invented by Mr. Li Guanqi of Huaxian County in Henan Province, belonging to the original invention in China. Its invention patent number is ZL.1. At present, the fruits of this invention are transformed into productive forces and a 10,000-ton-scale production base has been set up in Changshu City, Jiangsu Province. The real large-scale production of the two soybean fiber bases was 2003 and 2004 respectively. Along with the large-scale production, the inventor of soybean fiber Mr. Li Guanqi and other researchers developed the anti-ultraviolet function, far-infrared function and negative oxygen ion function of soybean fiber , Its current profile describes the domestic and foreign companies and consumers who use soy fiber to develop and produce their products. (For details, visit Yuan Xiu International ) Function one: the role and harm of ultraviolet light UV: UV disinfection with the role of anti-rickets can synthesize vitamin D, and therefore UV to humans and all creatures on Earth are necessary. UV wavelengths in the 180-400 nm range, according to the wavelength size is divided into UV-A (320-400nm), UV-B (290-320nm) and UV-C (180-290nm) three kinds of UV. Long-wave ultraviolet rays can tan the skin, wrinkles accelerate skin aging; UVB burns the skin, the skin becomes red blisters; shortwave UV is absorbed by the ozone layer 10-50km above the ground and can not reach the ground, shortwave UV is the most harmful ultraviolet . In recent years, due to a large number of freon and other halogen compounds remain in the earth above the earth, was decomposed by ultraviolet light to form active chlorine, and then a chain reaction with ozone, the ozone layer was destroyed, the shortwave ultraviolet rays may reach the ground. In short, UV long-term exposure to the human body, the light tanned the skin to increase freckles, butterfly spot; severe skin wrinkles, rhombic head and neck skin; the most serious UV can cut off the nucleus DNA (DNA) molecular chain, broken The DNA of the strand will be restored to its original state by the enzyme with the ability to repair. If this repair ability is weak, it is prone to skin cancer. To this end, people have developed a UV-resistant fibers, overalls made with this fiber, summer field work for a long time, such as military personnel, traffic police, geologists, construction workers wear this overalls, Can prevent UV penetration. Anti-UV fiber summer clothes can prevent the skin tan; automotive interior fabric with anti-UV fiber can reduce fade, prolong the aging time caused by ultraviolet radiation. Anti-UV fiber is a very promising development of functional fibers. ①References, Wang Shu, Wang Qingrui, Liu Zhaofeng edited "Introduction to high-tech fibers." Soybean protein fiber UV resistance: Soybean protein fiber has a strong UV absorption rate, according to the National Far-infrared product quality supervision and inspection center testing, soybean fiber knitted fabric UV absorption rate of 99.8% (see Table 1), can effectively prevent Skin cancer occurs. Function 2, far-infrared function Far-infrared fiber is a kind of fiber with infrared absorption and emission function, which can release far infrared ray of certain wavelength to the human body by absorbing the heat emitted by the human body or absorbing the energy of the outside world, which has the functions of warmth and health care . ② References, Wang Shuhe, Ma Xinan, eds., "Special function of textile development." Soybean fiber can radiate the same far infrared ray as human body biological wave spectrum (6-14um), and the far-infrared emissivity reaches more than 87% (see Table 2 for details). This far-infrared effect on the human body, that is, the resonance of human cells to activate the phenomenon of antibacterial, and promote blood circulation and blood flow, enhance immunity and other health care functions. Function Third, the negative oxygen ion function Air is composed of numerous molecules, atoms, when the air molecules or atoms lost or get the electrons, the formation of charged particles called ions, positively charged called positive ions, negatively charged called Negative ions. The mechanism of ionization of air molecules in the air: mainly rely on the results of the role of the external catalyst on the role of different gases, activin UV, radiation, photoelectric effect. Odd stone is a kind of catalyst, it can produce thermoelectric effect and piezoelectric effect under certain conditions. When temperature and pressure are present (even minor changes), they can also cause electrical differences between their crystals, which can reach as high as 1 million ev at energies sufficient to ionize the air, Adjacent molecules and make it into air negative ions, negative oxygen ions e-. Air negative oxygen ions in the air was Z-shaped movement. In the process of moving the negative charge to the continuous delivery of bacteria, dust, smoke particles and water droplets, the charge combined with these particles into a ball, and then fall to the ground, thus purifying the air. According to the "International Medical Journal" reported negative oxygen ion content and health as shown in Table 3. Thus, the body inhaled a small amount of negative oxygen ions a day, of great benefit to health, mainly in: 1, so that the body energetic, eliminate fatigue and burnout and improve work efficiency; 2, to improve sleep, eliminate neurasthenia; 3, Reduce the incidence of diseases, prevent colds and respiratory diseases; 4, to improve the symptoms of cardiovascular disease; 5, prevention of air-conditioning disease; 6, under the action of negative oxygen ions can increase the excitement of skeletal muscle, help to improve the performance of sports; , The body absorbs air negative oxygen ions, can reduce the central nervous system to accelerate the body's aging serotonin content, play an anti-aging effect; 8, negative oxygen ion fiber itself has a strong far-infrared emission function; 9, for the circulatory system , Can play the telangiectasia, enhance blood circulation, promote metabolism, enhance the circulation of lymph; 10, for cell tissue, cell activation, enhance cell function and vitality; for car decoration, to eliminate the car Odor, purify the air, regulate driver's nervous system excitement and inhibition, improve cerebral cortex function, keep the human body Good mental state; 11, negative oxygen ions fiber itself has high activity, has a strong oxidation-reduction action, can destroy the activity of the bacterial cell plasma membrane or enzyme activity, so as to achieve an antibacterial effect sterilization. ③ References, Dr. Wang Qi, Donghua University, China. After ten tests, the average emission values ​​of the two bleached pure soy fiber jersey negative ions are shown in Table 4. Function Fourth, the comfort of soybean fiber (touch comfort) Touch refers to the fiber material on the human hand and skin texture, warmth, soft feeling, smooth feel, adhesion, etc., these indicators are mostly intangible , More difficult to quantitative determination, is now five quantitative research. Now through the following four aspects of human touch to measure and evaluation. (1) fiber humidity, and the body's hot or cool related. (2) fiber temperature, and the body's sense of hot and cold. (3) fiber perspiration, and the body's adhesion or slippery feeling. (4) Friction coefficient and amount of compression of the fiber are related to the soft or stingy feeling of human skin. 1, soybean fiber moisture, water retention several times lower than cotton, the same weight of a knitted cotton underwear and a soybean underwear in the same washing machine by a washing and drying, outdoor cooling on the sun, in time, Then soybean underwear only one-third of the time cotton underwear dry, and wet underwear soybean fiber. 2, the test results of soybean fiber test results prove that far-infrared functionality, the soybean fiber infrared light emitted by its own micro-heat skin contact with the soybean fiber fabric is a warm feeling of skin temperature; 3, soybean fiber dumbbell type and Irregular kidney shape rich longitudinal groove shape, and the skin surface has convex island shape, its siphon liquid is very strong perspiration, people in strenuous exercise environment, human skin feel dry and comfortable; 4, the proportion of soybean fiber light, fineness Fine, low friction, strong skin contact with human skin.
