Description

A kind of flame-retardant aqueous polyurethane superfine fiber synthetic leather base cloth and manufacture method thereof

Technical field

The present invention relates to superfine fibre technical field of composite materials, be specifically related to a kind of flame-retardant aqueous polyurethane superfine fiber synthetic leather base cloth and manufacture method thereof.

Background technology

Twentieth century forties can be traced back in the source of fiber fine research, and what utilize synthetic fiber successfully to make composite fibre industrialization at first 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 respective method successfully to produce the superfine fibre differed from one another.Such as, the various composite fibre such as multi-core type, wood grain type, radial pattern, hollow radial pattern is developed.

Enter the eighties of last century later stage seventies, Dong Li company is therefrom subject to inspiration by analysis natural fabric and produces very uniform fibre technology.After the eighties, the characteristic that superfine fibre is good is subject to the favor of consumer, forms the Artificial Chamois Leather heat of today.

After having arrived eighties of last century nineties, many companies have released the fine denier filaments such as polyester, polyamide, polyacrylonitrile and polypropylene one after another in the world.Also there is the noun such as " fine count fiber ", " microfibre ", " superfine fibre " simultaneously, but there is no the unified definition about fine count fiber so far in the world.In the last few years, monofilament linear density was generally called superfine fibre lower than the fiber of 0.3dtex by Japanese chemical fibre industry.

Superfine fibre is because it, than traditional fiber finer, so have more fluffy, soft sense of touch than general fiber, and can overcome easy wrinkle, the air-locked shortcoming of artificial fibre of natural fabric.In addition, many excellent specific properties that can not be substituted such as it also has warming, not mouldy, free from insect pests, light weight, waterproof 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 produces non-weaving cloth.At present in China, tangerine lobe type bi-component micro staple fiber non-weaving cloth is mainly used in cleaning products, and the non-weaving cloth of the tangerine lobe bicomponent filament procedure of fibre production of top grade, then for leather base fabric, produces clothes and glove leather etc.
