Description
One, the technical field of invention:
The present invention relates to a kind of polyurethane artificial leather, be related specifically to a kind of Ji Bu of polyurethane artificial leather.
Two, background technology:
Leather is all that people live relevant a kind of requirement since ancient times, and in recent years due to the development of society, this natural leather can not meet demand.Therefore just there is artificial leather, wherein have the plastic products artificial leather of artificial leather and the large class of synthetic leather two.Be simultaneously that the regenerated leather of raw material also has new development, except traditional wet processing product with leather waste.With the regenerated leather of dry production, and also come out one after another (the Chinese patent patent No.: 02138602.1 title " a kind of synthetic leather and manufacturing technique thereof ") with a kind of synthetic leather product of the base cloth of nonwoven fabric construct.
Artificial leather and synthetic leather, they are two large class artificial leathers (ginsengs: Encyclopadia Sinica version 9-302 in 2009 closes he of different performance and different structure base cloth, 18-422 people ren) but their material of base cloth is all the conventional textile fabric of non-leather fiber, therefore just lacks the feature of natural leather.The patented product of above-mentioned mentioned " a kind of synthetic leather and manufacturing technique thereof ", it does not belong to like product of the present invention, although adopted leather fiber to make in scrim material, but the structure of composition base cloth is a kind of nonwoven fabric made without spinning process, therefore just determines the problem of its mechanical strength extreme difference.So the sanitation performance of existing artificial leather or mechanical performance all do not reach natural leather, they just constrain the scope of its application when alternative natural leather.
Have a kind of polyurethane artificial leather in the large class of existing product artificial leather, it take polyurethane as top layer, usually with chemical fibre be main conventional textile fabric have textiles for base cloth, so its sanitation performance does not far reach natural leather.
Three, the content of invention:
In order to manufacture a kind of sanitation performance and outward appearance of existing natural leather, have again the new product of a kind of artificial leather of the physical mechanical strength of natural leather, the polyurethane artificial leather that at this point the present invention is directed in existing artificial leather is transformed.It is comparatively large that the major defect of existing polyurethane artificial leather is that sanitation performance compares gap with natural leather, and determine that its sanitation performance principal element is its Ji Bu, so adopt new technology of the present invention to transform it for base cloth.
Technical scheme of the present invention is by the Ji Bu of existing polyurethane artificial leather, and employing leather collagen fiber is that the one of main raw material has textiles.
The present invention adopts the technology having textiles, and at Chinese patent number of patent application: 200910158852.2, title: open in the patent of " a kind of corium fabric leather and manufacturing technique thereof ", it discloses the fabric be woven into leather collagen fiber.Although flatness, the uniformity of this fabric are all improved, but these goods are still as just the use in regenerated leather category, and its surface is also without any plastic material layer, and this patent is also still last relates to the invention technical scheme disclosing this application.
Inventor herein is also one of inventor of above-mentioned patent, the existing use being applied in base cloth of the present invention with the patented product of foregoing invention.So this invention can think the continuity of foregoing invention, it is the dependent invention of an application.
The present invention realizes like this, " a kind of polyurethane artificial leather " of the present invention, comprising: top layer and Ji Bu, and its top layer is polyurethane is material, employing transfer process, spraying process form top layer, and make the similar various natural leather decorative pattern in top layer and color on base cloth.
The raw material of Ji Bu mainly regenerated leather are made, and its raw material is the leftover pieces of leather and good-for-nothing leather waste.Through following technological process; Bulk, the combing of leather leftover bits, screen, make leather collagen fiber, be main raw material and other textile fabrics of mixture with it, adopt and comprise the yarn that a kind of new spinning technique " high efficiency shortened process embedded composite spinning method " is spun into multiply, cloth is made into by the conventional method of weaving cotton cloth, transfer process is adopted for Ji Bu above with this cloth, spraying process forms the various decorative pattern on surface and the polyurethane skin layer of color, material has water-based or solvent borne, thus makes a kind of new product of polyurethane artificial leather.
In order to reach the performance and kishke feel with natural leather, also process to be processed especially to Ji Bu and goods.As: in order to make Ji Bu and top layer polyurethane material have good cohesiveness, need to fill and lead up the surface of base cloth, hacking, and remove the grease on surface with edible vegetable oil agent, thus reach the high-peeling strength of goods.Also to be aided with shake soft, soft line and the back side after making goods and do suede, reach kishke feel and the outward appearance of simulation natural leather.Need to carry out multiple test repeatedly to every, and in combination production, relevant art and technical parameter are determined in practice.
Technology of the present invention is not the replacement of the base cloth of identical function, and the scrim material of the polyurethane artificial leather of prior art is chemical fibre is main traditional fibre, and the technology being woven into base cloth is also traditional technology.Scrim material of the present invention is pencil leather collagen fiber, and adopts unique new spinning method to be spun into multistrand compound wire.So the material of base cloth of the present invention, make yarn.Structure and institute's function of bringing not identical with prior art, simultaneously also polyurethane artificial leather, made any similar application from end before this.
The goods adopting new technology of the present invention to make are compared with prior art goods polyurethane artificial leather and are had greatly improved, and except reaching the suitable mechanical strength of natural leather, close diopter, flatness, also produce some beyond thought good effects.
As: a kind of footwear leather adopting the technology of the present invention to make, its physical and mechanical properties all technical has reached the requirement of footwear leather, and has outward appearance and the feel of natural leather.With the male leather shoes that this leather is made, when people wear, foot end feels any vexed wet, has the comfort that same natural leather leather shoes are identical.With the leather and fur products of the skin contact of production footwear of the present invention, clothing these and people, beyond thought compatibility is just had when wearing, the various disease of skin that the goods of prior art products polyurethane artificial leather cause can be avoided, so it just has the sanitation performance of natural leather.
The base cloth of this patent product is raw materials used is that its costs of regeneration of the leftover bits of leather is low, the technology manufactured is the technology of this patent, its leather and fur products can substitute the medium and high-grade commodity in natural leather, overcoming recycled product in the past can only be used as in low-grade or auxiliary material, this is the commodity that a kind of cost performance is high in the market, thus has opened up out market.The success of these commercial acquisitions is by the direct result of the technology of the present invention progress completely.
