Since the 1950s, the varieties of fiber raw materials processed by the cotton textile industry have been continuously increasing. Viscose staple fibers, polyester staple fibers, vinylon staple fibers and nylon staple fibers have gradually become important raw materials for the cotton textile industry and expanded the cotton textile products A series of new areas. YAO Mu academician of textile materials experts pointed out that after 1980, a series of short fibers into the field of cotton textile processing, including cashmere, ramie, apocynum, high moisture modulus viscose fiber, solvent spun viscose fiber, acrylic, polypropylene, Lun and other one after another into the cotton textile industry. After 1987, a variety of "differential fiber" first entered the cotton textile processing industry. Made by Australia, "Siro spinning" and so on, so that the raw material of cotton textile industry not only the use of short fibers also began to use filament. The development of new spinning methods include parallel spinning, filament winding rotor spinning, embedded composite spinning and so on, further introducing silk and chemical fiber filaments into the cotton textile processing industry. With the continuous innovation and long-term development of cotton textile processing technology and cotton textile equipment, cotton spinning expands from traditional ring spinning and rotor spinning to Siro spinning, cable spinning, parallel spinning, Siro spinning, dust cage spinning, jet spinning, wrapped spinning, eddy spinning. And in the ring spinning machine to transform the formation of concentrated spinning (compact spinning), embedded composite spinning, etc., but also in the rotor spinning (ie, air spinning) to produce wrapped yarn and so on. On this basis, the varieties of fiber raw materials that can be used for the ring spinning system and the rotor spinning system of cotton spinning expand significantly. Currently, there are dozens of varieties of staple fiber and filament yarn, including cotton fiber, kapok fiber, ramie, finely processed flax, jute, apocynum, hemp, bamboo fiber, cashmere, yak Velvet, down and so on. The ideal green fiber outlook The first half of the 21st century, global food security will be the primary issue. Fiber textile raw materials are facing a new test. Under such conditions, the raw materials for the cotton textile industry are facing new demands and new opportunities. The call for new fibers is also getting stronger and stronger. Kapok fiber has become a new type of cellulose fiber. Kapok that Panzhihua, also known as red cotton, the hero tree, is a large tree deciduous, is a kapok Branch, mainly in China's Yunnan, Guangxi, Sichuan, Guangdong, Hainan, Fujian, Taiwan and other provinces (regions), foreign Vietnam, India, Myanmar Java is also distributed. Xiong Dingguo, assistant secretary general of China Desertification Foundation and secretary general of Beijing Hongmu Cotton Engineering Technology Development Center introduced that kapok fiber is natural and light, with moderate elasticity and vegetable fat on the surface, which makes the fiber appearance smooth, soft and not easily tangled , And will not permeate. Kapok fiber also has a mildew, not eaten, at room temperature, acid and alkali, anti-static, flooding mite antibacterial and other special advantages. Can be widely used in aviation, navigation, military, medicine, construction and other fields. In fact, the history of the application of kapok is very old, ancient made of bed linen with kapok, Yunnan ethnic minorities with kapok do the daughter dowry. Ancient "kapok" and other handmade kapok textiles. However, kapok fiber is difficult to be modern mechanized processing, modern kapok completely out of the textile field. When talking about the development and application of kapok textiles, Professor Wang Fumei of Donghua University pointed out that the kapok fiber has a hollowness of more than 80% and is closed at both ends, which has the characteristics of good warmth, small volume and light weight, and good buoyancy. Kapok is a natural microfiber with a linear density of 0.4 ~ 0.8dtex, while the linear density of cotton fiber is about 1.5 dtex. Microfiber is an important research and development direction of chemical fiber at present, and has unprecedented properties of ordinary fiber. Kapok is a natural cellulose fiber, and cotton, rayon have a lot of similar properties, is a very ideal green environment-friendly fiber. The development of kapok planting is of great interest to the textile industry. China imports 3 million to 4 million tons of raw cotton each year. At the same time, China is the first major importer of wool in the world. In addition, a larger raw material gap accounts for 65% of the total fiber content, derived from petroleum. The application of kapok fiber to the textile industry will ease the tension of the textile fiber raw material. At the same time, the kapok growth environment is wide and it can help the poor areas to develop their economy. The development of kapok fiber has a certain technical difficulty, the existing products are only primary products, in the open-cotton, carding, spinning, product design and finishing aspects of the technical level also needs to be improved. There is also a need to develop more kapok-specific equipment. At present, the application of kapok fiber in textile field already has some technical foundation. Shanghai climbing large Kapok Science and Technology Co., Ltd., after scientific research, breakthroughs in textile technology, rewrite the "Encyclopedia" Kapok should only be done on the filler should not be spinning conclusion. In March 2009, Honghe Pangda Textile Co., Ltd. was established to form an annual production capacity of 3,000 tons / year of air-jet spun cotton yarn, which can produce 2 to 40 kapok yarn. New fibers bring market vitality Rapid development and upgrading of the textile industry, making a variety of new fibers and functional fibers are widely used in the textile field, which also makes the traditional textile varieties from the past to diversify. With the accumulation of experience and technological breakthroughs, the mutual combination of various fibers, that is, the blended yarn, almost realizes the possibilities of various combinations as desired, and eventually forms an almost infinite variety of combinations. Texas Huayuan ecological technology can be called a variety of fiber blended "experts", the general manager Zhang Lanfeng introduced in 2008, the company purchased more than 800 batches of raw materials, involving more than 50 species of nearly 100 kinds of specifications. Raw materials involved a variety of natural and chemical fibers. Natural fiber covers cotton, wool, silk, hemp, cashmere and other varieties. Chemical fiber to a new type of cellulose fibers, both differentiated polyester, acrylic, milk fiber, corn fiber and other chemical fibers. At present, Huayuan Eco-Technology Co., Ltd. accounts for about 4.2% of pure spinning, two-component blending is about 58.5%, three-component blending about 28.1% and four-component blending about 3.2%. In a variety of new fiber materials in the application of textile enterprises experience a lot. Huayuan eco-technology company concluded that a variety of fiber blends has three major advantages, first of all to adapt to a wide range of users. As a result of a variety of fiber applications and blends, the variety of patterns and varieties of relatively large number, so the corresponding customer base is also more extensive, the company's market contacts more access to the market information is relatively more extensive for the company Development orientation to lay the foundation. Second is the market flexibility. Because it is multi-species, small batch production, relative to the market in terms of superior flexibility, can keep up with changes in the market changes, more convenient variety changes. The third is good economic returns. Due to the tediousness of the production process of a variety of fiber blended yarn, as well as the characteristics of the yarn itself, the production and processing costs of the yarn are relatively high, at the same time the economic benefits are relatively better. Of course, a variety of fiber blends also exist drawbacks need to be noted in the production process of textile enterprises. Due to the mutual existence of many kinds of fibers, in the production of various kinds of fiber blended yarns, in order to meet the simultaneous production of many kinds of fibers, in the production equipment of the previous process, More than the normal cotton spinning with more than about 30% of the amount, so that from the equipment management, the difficulty is also larger than normal. The chances of fiber mixing are increased, and when multiple fibers are simultaneously online, the probability of confusion between the fibers is much greater than when producing a single product. Due to the large differences in the properties of the fibers, no matter what kind of fibers enter the other fibers, it will result in complaints and claims in later procedures. Increase the production site occupies fixed assets, in order to solve the problem of mutual confusion between fibers in the production site to be larger than the normal machine to arrange space, which is nothing more than increasing investment in fixed assets, while the production site to implement the machine and machine The isolation of each other, to the entire production site management has brought great difficulty. The difficulty and complexity of management increase. In terms of production management, the difficulty and complexity of management are relatively large due to the variety of fiber types and varieties, such as feeding schedule, variety schedule control, collecting and storing back flowers, etc. , A little bit of consideration will cause confusion between the fibers. Change the spinning more frequently, is not conducive to the quality and stability, due to many varieties, small quantities of production patterns, resulting in the phenomenon of changing the production workshop more frequently. According to incomplete statistics, Huayuan Company currently has more than 1,000 sets of spinning / spinning machines per month. This phenomenon brings great difficulty to the stability control of product quality. Parts of non-unique equipment, due to the performance of a variety of fiber differences, the required parts of different equipment, so for different fibers in the selection of spare parts and equipment supporting the management of more difficult.
