The invention is characterized in that it eliminates the chromatic difference in the reverse side of the leather by a simple process, and handling the reverse side of the leather to material with an surface effect of woollen material, knap surface and cloth, it also can improve the leather quality, upgrade the class, enlarge the applying area and increase the economic value of leather.
Description
Technical field
The invention belongs to the leather processing field, relate to a kind of natural suede leather producing process.
Background technology
Natural leather leans on the leather surface of animal muscle one side to be called as the reverse side of leather, has one deck fine hair on this reverse side leather substrate.Usually the reverse side of leather is done the front when article such as use natural leather making clothes, the leather that is used as this purposes is called suede.Through the natural suede after the existing leather processing art breading, there is one deck suede fiber on its surface, generally be called pile, pile on this suede is erect and is toppled over irregular, visual effect is bad, and pile lodging after stroking makes whole fabric produce aberration, after dress is used and is rubbed, then can balling-up.Thus, this kind suede can not be made high-grade haberdashery.
At the problems referred to above, China Patent No. is that 93103655.0 patents of invention that are called " buff leather " disclose a kind of buff technology, it is to be provided with a coating on the surface of crust leather, on coating, establish tapetum, by tapetum the fibrous tissue of crust leather surface porosity and coarse grain are covered and make low-grade corium become high-grade velour.The suede that this method is made has reduced the ventilation property of leather, and simultaneously, the tapetum that lays comes off in the middle of using easily, has again, and this leather surface method for quality of improving also is a more complicated.
Chinese patent application number is 98118977.6 and is called " treatment process of natural suede leather " patent of invention to disclose a kind of feel treatment process of making natural suede leather, at least also has " feel processing " operation together after " stuffing " operation of i.e. technical process routinely, be somebody's turn to do the technical scheme that " feel processing " operation adopts modified organic silicon emulsion (microemulsion) to handle, natural suede leather product after make handling has fine and smooth good hand feeling as the excellent competent smooth and cheese, and has certain anti-mildew sex change.This technology is fairly simple, but its visual effect of leather and aberration that the above-mentioned art breading of process is crossed are still relatively poor.
Summary of the invention
The objective of the invention is to change natural leather reverse side pile layer poor visual effect, have the problem of aberration and easy balling-up, the front surface of a kind of reverse side of natural leather as articles for use such as clothes is provided, it has the suede of woollen cloth, matte cloth or even cloth cover cloth surface effect, can make high-grade clothes, articles for use etc. with it, can also make the underwear articles for use.
The object of the present invention is achieved like this:
The exsiccant leather that processes such as process skin base eases back, tanning, shaving are made is called backboard, is raw material with the backboard, makes suede by following steps:
1, with the pile layer of flame calcination leather reverse side, makes its carbonization;
2, with napping machine (skin grinder) the leather reverse side is ground processing, when grinding off carbonized pile, form new matte.
Key of the present invention is natural leather reverse side top layer inherent pile layer is got rid of, again on the leather substrate by grinding operation, grind the different new suede layer of length as required, the suede layer uniformity that newly grinds out is so the surface of suede can occur and the visual effect woollen, that matte is the same with the cloth cover cloth.
Grinding off the inherent pile layer, is very difficult, because leather quality softness, fine hair is difficult for being worn away.If leather is made hardening treatment, make the leather substrate hardening, grind then, perhaps can remove pile, still, the leather quality variation of having hardened, the scope of application of the making dress-goods of this leather diminishes, just can't be with this leatherwork such as clothes such as underwears.
And the making method of suede provided by the invention is just carried out calcination to the pile layer on the leather, and it is become fragile, and remove and a new suede by grinding technology, and the quality of leather does not change at all again.Therefore, the suede made from present method can keep the original characteristic of leather.Supple leather also can be made the good suede of visual effect, and such suede can become the good material of making underwear.
Particularly, the described pile layer of calcination can be used liquefied gas spray gun, gasoline spray gun or alcohol spray gun.For fear of the basic unit of damage leather, should guarantee the temperature of flame of calcination leather and the duration of contact of flame and leather surface.The kind difference of leather, the thickness difference of leather, tapetum thickness difference, the temperature of calcination flame and also can have nothing in common with each other with duration of contact of leather surface.Usually, the flame temperature of contact leather is at 200-350 degree centigrade, and the residence time on leather is 0.05-0.5 second.The selection of actual temp and time is all so that pile layer carbonization and do not injure leather substrate and be as the criterion.
Further,, also to carry out frosted and handle the front of leather for ventilation property, flexibility and the elasticity that improves suede, with the epidermis of grain side of leather all with partly worn.As being used to make underwear ground suede, its grain side of leather ground epidermis should be all worn.And make the leather of coat or bag sofa, its positive epidermis is can part worn.Worn thorough more of front epidermis, ventilation property, flexibility and elasticity are good more.
Method of the present invention can be widely used in various natural leathers, as pig suede, pig split, three layers of pigs, the anti-suede of sheep, the anti-suede of goat, Niu Fanrong, cow split, three layers of oxen, suede nap, deer velvet and kangaroo velour and Buffed leather suede, fur one leather suede etc.
Suede leather producing process provided by the invention just can will have been eliminated the aberration of original leather reverse side pile layer by foolproof technological process, the reverse side of natural leather is processed into have woollen cloth, the material of matte or cloth cover lining surface effect, can improve leather quality, and its class is improved greatly, enlarge its use range, promote the economic worth of leather.
Description of drawings
The invention will be further described below in conjunction with embodiment.
Embodiment
Use goatskin to make suede of the present invention.Raw material is the backboard of goatskin.
At first its reverse side is carried out the flame calcination, to its calcination, the liquefied gas spray gun is apart from 20 centimetres of leathers with the liquefied gas spray gun, and the flame temperature of contact leather is between about 280-300 degree centigrade, and the time that flame stops on leather during calcination is approximately 0.3 second.By such calcination, can be with the pile carbonization on the leather reverse side.
Then, leather is placed on the existing napping machine (skin grinder) carries out napping, used napping gauze is about the 600-800 order, and the suede that grinds has the matte effect.If the face of acquisition effect then will be used 800-1000 purpose napping gauze,, then to use the napping sand paper about the 1000-1200 order if obtain the cloth cover effect.
