The History of Microfiber Development
Apr 02, 2018

      The fiber superfine source can be traced back to the artificial silk era of two-component composite fiber (conjugated fiber) in the 1940s. The first to use synthetic fiber successfully to make the composite fiber is still the DuPont company in the United States. This method is used to produce self - crimping fiber. From 1962 to 1965, Japan toray, kanebo, teijin, coke and other companies to use their own special spinning method developed multi-layer structured method and stripping method, successfully create distinctive superfine fibers.                                                                                                                                                                                                                                                                     For example, various kinds of composite fibers such as multi-core type, wood grain type, radial type and hollow radiation type are developed. Into the late 70 s, the use of superfine fiber emulation silk fabrics, and high density fabric appear constantly, through the analysis of natural fiber inspired, develop manufacturing narrow limits, and very uniform fiber technology. The fibers used in this technique are called polymers arranged in a fiber. At that time, the fiber was well received in the country, and it was highly praised at the Paris international exhibition several years later. After entering the 1980s, the excellent properties of ultrafine fibers are popular with the public, forming today's artificial suede heat.                                                                                                                                                                                                                                                                                                                                                                                       By the 1990s, many companies in the world have introduced polyester, polyamide, polyacrylonitrile and polypropylene filament. At the same time, there are also nouns such as "fine denier fiber", "fine fiber" and "superfine fiber". However, there is no uniform definition of fine denier fiber in the world. In recent years, Japan's chemical fiber industry has generally referred to the fiber of less than 0.3dtex as ultrafine fiber.

      In addition, because of superfine fiber and has developed into a major indicators of future fiber industrial competitiveness, and because the composite superfine fiber has different performance of the conventional fiber, which makes the products have many unusual characteristics, and hence step into many application fields. At present, the main products of the world fiber are the ultra-fine fiber, which is the most famous. Now, the countries and regions that mainly produce the ultra-fine fiber should be Japan, the United States and Western Europe.
