Development of Microfiber Leather

Dimensional ultra-fine people for a long time pursuit of natural fibers in the early use of the minimum fineness of wool, silk represents the elegant, people of all ages. But fine denier synthetic fibers began in composite spinning technology in the true sense of successful development. Ultrafine synthetic fiber derived from natural people constantly simulation and beyond, while the continuous development and the pursuit of functional fibrous materials, chemical fiber as a representative of the high-tech, high simulation-oriented development of a new generation of synthetic fiber, its development process can be divided into several stages.


First stage: initial microfiber is wool imitation. Superfine fiber origins can be traced back to the 1940s, that is, imitation wool fiber two-phase structure of bicomponent fiber (conjugate fiber) rayon era. The first to use synthetic succeeded in making bicomponent fibers practical American DuPont. The method utilizes parallel composite fibers produced from crimped success, DuPont has spun out of polyacrylonitrile and polyamide composite fine fibers.


Phase II: subsequent microfiber is silk imitation. Around 1960, the Japanese textile companies to imitate silk, the first commercial bicomponent fiber available, relatively simple structure, the use of parallel type, sheath-core type. But this single fine synthetic fibers with the application of conventional synthetic comparison, feel too soft, the quality of the fabric showing overcapacity, low elongation recovery capability, and poor staining. Then in 1965, Toray, Kanebo, Teijin, Kuraray and other Japanese companies use different methods to develop a multi-layer structure of the special spinning and lift-off method, we succeeded in producing microfiber distinctive, for example, multi-core type, split type, radiation type and other composite fibers. Later in the manufacture of suede success and breakthrough technology, available in fine natural suede microfiber imitation. Later fine fibers become modern industrial production of high-grade synthetic suede materials, and welcomed by the market.

Phase III: With the development of synthetic fiber industry and consumers continue to improve on the performance requirements of the 1970s have undergone a period of modification of synthetic fiber. But merely mimic the performance of the modified natural fibers can not meet consumer demand. By the 1980s, the major companies while continuing to focus on synthetic natural-based, but also dedicated to discovering the special features of chemical fiber has, with superb technology developed natural fibers are also difficult to compare with high performance, high value-added fiber material, "new synthetic fiber" is a new type of ultra-fine fibers as the representative of the fibrous material.


The fourth stage: since 1986, is the era of global research and excavation microfiber function, mainly to explore the microfiber has the features and functions. Microfiberis certainly a good performance, applications continue to expand, many large companies launch countries polyesters, polyamides, polyacrylonitrile and other new varieties of ultra-fine fibers, for the further development of ultra-fine fibers in the broader field of providing a basis for the development of ultra-fine fibers show new prospects. Currently the world's major fiber products superfine fiber most attention, now mainly produces ultra-fine fibers of countries and regions as Japan, the United States, Western Europe.
