Abstract
The invention relates to a full-grain elastic leather. The full-grain elastic leather is of a two-layer structure, wherein a surface layer is full-grain leather and a lining layer is an elastic fabric; and two layers of the full-grain leather and the elastic fabric are compounded together via glue so as to form the two-layer full-grain elastic leather. A processing technology for the full-grain elastic leather comprises the following steps: sorting of chrome splits; tanning of gray leather; splitting: a step of splitting off grain leather with a thickness of 0.25 to 0.30 cm; compounding: a step of compounding the full-grain leather part and the elastic fabric together via the glue so as to form the two-layer full-grain elastic leather; dyeing; and after-treatment so as to obtain the full-grain elastic leather. According to the invention, the gray leather produced in traditional leather making process is split by using mechanical equipment and then compounded with the elastic leather, so the obtained full-grain elastic leather has a thickness greater than the thickness of conventional large leather, higher tear strength, high elasticity and a wide application scope.
Description
Technical field
The present invention relates to leather industry and textile industry field, be specifically related to a kind of light face elastic force skin and processing technology thereof.
Background technology
The structure of the skin of the animals such as mammality, by the mutually different epidermal area of institutional framework and skin corium, this is two-layerly formed.The skin obtained from animal is processed into leather through following process, and is provided with using.First, depilation process is carried out to skin, removes epidermal area, thus obtain skin corium.Skin corium mainly comprises crisscross collagenous fibres, and collagenous fibres contribute to the high physical strength maintaining leather.
Skin corium, according to its institutional framework, can be divided into the papillaris pars of side, top layer and the lamina reticularis of internal layer side.Papillaris pars comprises the surface being referred to as grain, and this grain has the outward appearance of the intrinsic concavo-convex grain pattern of animal and smooth grace.Cutting stripping from the upper epidermis of papillaris pars to lamina reticularis top, and after the process such as tanning process, dyeing process is carried out to the upper epidermis of gained, its surface is being applied, thus the leather products being referred to as to be with grain leather can be obtained.Band grain leather, because of its attractive appearance, is preferably applied to the purposes such as shoes, dress material, bag class, groceries, furniture, automobile inside.But along with the raising of people's living standard, existing smooth musculus cutaneus product can not meet the requirement of people to comfort level, and intensity is not high, and range of application is narrow.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and a kind of light face elastic force skin and processing technology thereof are provided, this light face elastic force skin by the crust leather that produces in conventional leather making processes by plant equipment delamination, then by it and band textile compound springy, the Final finishing eventually passing product obtains finished product, and this product has the features such as high resiliency, good comfortableness, applied range.
Above-mentioned technical problem of the present invention is mainly solved by following proposal: a kind of light face elastic force skin, comprises double-layer structure, and top layer is light musculus cutaneus, and nexine is stretch fabric, and described smooth musculus cutaneus and stretch fabric are compounded to form light face elastic force skin by glue.
As preferably, described smooth musculus cutaneus is the light musculus cutaneus layer after crust leather split.
This light face elastic force skin is by the crust leather that produces in conventional leather making processes by plant equipment delamination, and then by it and band textile compound springy, the leather thicknesses obtained reaches the thickness of existing great Pi, and tearing strength is higher, and comfort level is better, applied range.
The invention also discloses the processing technology of a kind of light face elastic force skin, comprise the steps: (1) blue plate sorting: grade is better, and larger blue skin of opening a business sorts out, and treats retanning; (2) tanning openpore; Process for tanning condition is liquor ratio 1:5-10, temperature 30-60 DEG C, and rotary drum turns 1-3 hour, adds stone flour, regulates PH; (3) split; By openpore by splitter split, thickness is 0.25-0.30mm (4) compound: step (1)-(3) are processed the light musculus cutaneus part obtained and stretch fabric is compounded to form light face elastic force skin by glue; (5) dye; (6) Final finishing obtains finished product light face elastic force skin.
The light face elastic force skin that above-mentioned processing technology obtains, by the skin base of traditional process hides by plant equipment delamination, then by it and band textile compound springy, the leather thicknesses obtained reaches the thickness of existing great Pi, and tearing strength is higher, has high resiliency, good comfortableness, range of application is also wide.
Detailed description of the invention
Describe the present invention further below in conjunction with embodiment, but the present invention is not by the restriction of embodiment:
The present invention is a kind of two layers of light face elastic force skin, and comprise double-layer structure, top layer is light musculus cutaneus, and nexine is stretch fabric, and described smooth musculus cutaneus and stretch fabric are compounded to form two layers of light face elastic force skin by glue.
The invention also discloses the processing technology of a kind of light face elastic force skin, comprise the steps: (1) blue plate sorting: grade is better, and larger blue skin of opening a business sorts out, and treats retanning; (2) tanning openpore; Process for tanning condition is liquor ratio 1:5-10, temperature 30-60 DEG C, and rotary drum turns 1-3 hour, adds stone flour, regulates PH; (3) split; By openpore by splitter split, thickness is 0.25-0.30mm; (4) compound: step (1)-(3) are processed the light musculus cutaneus part obtained and stretch fabric is compounded to form light face elastic force skin by glue; (5) dye: (6) Final finishing obtains finished product light face elastic force skin.
The light face elastic force skin that above-mentioned processing technology obtains, by the skin base of traditional tanning production by plant equipment delamination, then by it and band textile compound springy, the leather thicknesses obtained reaches the thickness of existing great Pi, and tearing strength is higher, have high resiliency, good comfortableness, range of application is also wide.
Finally, it should be pointed out that above embodiment is only the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to above-described embodiment, can also have a lot of distortion.All distortion that those of ordinary skill in the art can directly derive from content disclosed by the invention or associate, all should think protection scope of the present invention.
