Background technology
Twentieth century forties can be traced back in the source of fiber fine research, and what utilize at first that synthetic fiber successfully make composite fibre industrialization is the E.I.Du Pont Company of the U.S..
The companies such as between 1962-1965, toray, clock spin, Supreme Being people, Kuraray utilize method separately successfully to produce the superfine fibre differing from one another.For example, the various composite fibres such as multi-core type, wood grain type, radial pattern, hollow radial pattern are developed.
Enter the eighties of last century later stage seventies, Dong Li company is therefrom subject to inspiration by analysis natural fabric and produces fibre technology very uniformly.After the eighties, the characteristic that superfine fibre is good is subject to consumer's favor, forms the Artificial Chamois Leather heat of today.
Arrived eighties of last century after the nineties, many companies release the fine denier filaments such as polyester, polyamide, polyacrylonitrile and polypropylene one after another in the world.Also there is the nouns such as " fine count fiber ", " microfibre ", " superfine fibre ", yet there is no in the world so far the unified definition of relevant fine count fiber simultaneously.In the last few years, Japanese chemical fibre industry was generally called superfine fibre by monofilament linear density lower than the fiber of 0.3dtex.
Superfine fibre is because it,, than traditional fiber finer, so have more fluffy, soft sense of touch than general fiber, and can overcome the air-locked shortcoming of easy wrinkle, artificial fibre of natural fabric.In addition, it also has warming, not mouldy, free from insect pests, light weight, waterproof many excellent specific properties that can not be substituted such as even absorb water.
The purposes of superfine fibre is more and more extensive, and is progressively applied in the aspects such as senior clad material, medical protective material, fine filtering material, senior polishing material.
Tangerine lobe type bi-component superfine fibre can adopt water thorn, needling process to produce non-weaving cloth.In China, tangerine lobe type bi-component micro staple fiber non-weaving cloth is mainly used in cleaning products at present, and the non-weaving cloth of high-grade tangerine lobe bicomponent filament procedure of fibre production, for leather base fabric, is produced clothes and glove leather etc.
