As one of the top ten fiber types for the 2012/2013 fiber trend in China, the name of the special-shaped fine-dense and moisture-wicking fiber should be unfamiliar to many people. However, such a new type of fiber relies on its profiled cross-section, and utilizes numerous micro-holes or grooves on the surface, combined with fine denier, so that the fiber can rapidly absorb moisture and sweat on the skin surface, and is transmitted to the outer layer through diffusion to evaporate. Can achieve moisture wicking effect. With the combination of anti-ultraviolet radiation, antibacterial and other multi-functional composites to further improve the function of the fiber, special-shaped fine denier moisture wicking polyester fiber has become a kind of fiber favored by sports brand buyers. Â
Special section brings comfort Â
The function principle of special-shaped fine-densing moisture-reducing perspiration polyester fiber mainly comes from its variant fiber cross-section. The highly profiled fiber cross-section structure and the fluffy yarn structure increase the "capillary tube" effect of the yarn. The capillary channels on or between the fibers can quickly absorb, transport, diffuse, and evaporate moisture to keep the human skin dry. The fine fibers on the surface of fine-denier textiles form numerous fine concave-convex structures, which are equivalent to countless capillary channels. Therefore, the absorption effect of fabrics is significantly increased, which can play a role in transferring water molecules, greatly improving the breathability of fabrics and guiding sweat. performance. Compared with conventional moisture wicking fibers, fine denier shaped fibers have fine densities, large specific surface areas, irregular grooves, and the like, which can greatly increase the hygroscopicity and moisture absorption of polyester fibers, and greatly improve comfort. Â
In terms of production, the polymer manufacturing stage of the heterogeneous fine denier moisture wicking fiber lays the foundation for the production of fibers for high moisture absorption and wicking fabrics during polymer polymerization. In the fiber manufacturing stage, hydrophilic polymer spinning is used to change the shape of the spinneret holes to prepare shaped fibers, longitudinal grooves are formed in the shaped fibers, and in combination with the preparation technology of the ultrafine fibers, the functions of moisture absorption and perspiration of the fibers are further provided. From the current moisture absorption and perspiration fibers, it is mainly spinning special fibers such as “Tenâ€, “Yâ€, and “U†shapes. At the yarn and fabric manufacturing stage, fibers with excellent water absorption properties are blended into yarns or composed of hydrophilic fibers and hydrophobic fibers. The inner layer is composed of hydrophobic moisture-conducting fibers, and the outer layer is used for sweat absorption and perspiration. Dry fiber composition. Â
The special fine denier moisture wicking fibers formed through polymer polymerization, spinning, yarn and fabric weaving, and integration processes combine the comfort of cotton with the quick-drying properties of polyester, leading to moisture fast drying, dry breathability. In addition, the high-profile cross-section structure reduces the volume weight by 25% compared to ordinary polyester, and is lightweight and comfortable. It is a good material for making tights and sportswear. Â
Breakthrough in product refinement Â
The main technical bottleneck in the development of special-shaped fine-diameter moisture wicking polyester fiber in China is still the fiber forming theory and professional spinneret processing accuracy problems, in which the design of high-precision heterogeneous multi-hole spinneret needs the support of spinning fluid mechanics theory. The processing of cross-section porous spinnerets requires high-precision spinneret processing technologies. These are the theories and technologies that the technical personnel in the chemical fiber industry in China need to gradually improve in the future work. There is still a certain gap between China and foreign countries in the technical level of special-type fine-densing moisture wicking polyester fiber. The main features are: the specific surface area of ​​the fiber is not large, the cross-sectional shape is relatively simple, and only the cross-shaped, Y-shaped cross section is used for the function of moisture absorption and perspiration. More development, and foreign countries have developed a flat section. Â
However, this gap is continuously narrowing. According to reports, in March 2003, Suzhou Jinhui Fiber New Material Co., Ltd. began to increase the development of the moisture absorption and perspiration function of polyester fiber, there are still some technical obstacles in the spinning production, and the fiber can not be refined, the product price It is much higher than ordinary products, and the promotion of moisture absorption and perspiration products is limited. Nowadays, in the production method, due to the breakthrough in ring blowing technology, fine denier and ultrafine fibers have already achieved industrial production. In addition, nowadays, special-shaped fine-denier moisture-removing and perspiration-removing polyester fibers are compounded with other functions, such as nano-powders through the combination of profiled cross-sections, and the added value of fibers through component control, fiber structure control, etc. Have a better market effect. Â
Fine denier perspiration wicking polyester fibers also have their own insurmountable disadvantages. Fine denier fibers have a certain amount of reflected light on each surface. Therefore, the finer the fiber denier, the more difficult it is to dye dark colors, and it is also easy to dye unevenly. Compared with the conventional polyester fiber, the light fastness of the fine denier fiber is lower by 1 to 2, and the finer the fiber, the larger the surface area, and the greater the light fastness decrease. Â
Significant achievements in industrial development Â
According to experts' predictions, going out of leisure clothes will guide the sports and leisure market to reach a growth rate of 30%. Therefore, in the aspects of sportswear and casual wear, the special-shaped fine denier moisture-reducing polyester fiber has unlimited potential for future market development. In China, a group of companies represented by Jiangsu Hengli Chemical Fiber Co., Ltd., Jiangsu Shenghong Technology Co., Ltd., and Suzhou Jinhui Fiber New Material Co., Ltd. are committed to the development and industrialization of such fibers, and have achieved remarkable results. Â
Shenghong Technology has made remarkable achievements in the development of fiber cross-section morphology, and has successively formed the research and development of “three-leafâ€, “five-leafâ€, “10â€-shaped, “Wâ€-shaped, and composite-shaped moisture-absorbing and wicking polyester fibers. Taking advantage of the company's ring blowing technology and adopting a new professional fine-denier multi-hole spinneret design, it has successfully developed various types of special-shaped fine denier moisture-reducing perspiration polyester fibers. At present, Shenghong annually produces more than 20,000 tons of special-shaped fine denier moisture-reducing wicking polyester fiber, and has formed a well-known brand "Ice Ice". Â
In respect of fiber fineness, the development of Jiangsu Hengli Chemical Fiber Co., Ltd. has received attention. The project entitled “Key Technology Development of High-quality Melt Spinning Superfine Polyester Filament†won the second prize of National Science and Technology Progress Award. Constant force inside and outside the United Nations experts, after many years of research, the monofilament fiber fineness of 0.3 denier, equivalent to 1/20 of a hair. Â
The temperature-regulating wire developed by Suzhou Jinhui Fiber New Material Co., Ltd. has given special-shaped fine denier moisture-wicking polyester fiber functionality such as antibacterial, anti-UV, and cool, and further enhanced the moisture absorption and perspiration fiber characteristics. Â
Faced with increasing pressures for industrial upgrading, chemical fiber companies have in fact placed high-tech, high-value-added products on R&D and promotion in a very important position. Shaped fine denier moisture wicking fiber will be the focus of future differential fiber development. As a major breed of high-comfort fiber, it is expected that the global production of special-shape fine-sweat moisture-reducing polyester fiber will gradually reach or exceed 2 million tons. At present, Hengli Chemical Fiber's profiled fine denier moisture-wicking fiber has been extensively cooperated with well-known companies such as Buick, Honda, and Li Ning, and has achieved good results. The person in charge of the related department of Shenghong Technology also stated that the company's special-shaped fine-diameter moisture wicking polyester fiber has established long-term use agreements with Nike, Adidas, Li Ning and other well-known brands at home and abroad, and they will gradually increase this category in the future. Product development and promotion efforts make this new type of fiber more effective. Â
