Description

A kind of corium is made leather

Technical field

The utility model relates to a kind of corium and makes leather, and particularly a kind of corium with local damascene structures is made leather, belongs to the leather technology field.

Background technology

Corium is made leather and is made up of epidermal area and skin corium, and wherein the epidermal area fibrous texture the most closely, pore is the finest and closely woven, and intensity and sweating character can be best, have natural slick appearance surfaces; Epidermal area is following is skin corium, tight more the closer to the skin corium fibrous texture of epidermal area, pore is fine and closely woven more, and intensity and sweating character can be good more; Skin corium fibrous texture away from epidermal area is loose more more, pore is thick more, and intensity and sweating character can be poor more; Positive and negative two surfaces of skin corium behind the removal epidermal area are coarse fibrous texture, must could form slick appearance surfaces by surface treatments such as artificial overlay films.In leather industry, generally comprise epidermal area and the skin corium branch of close epidermal area cut off as the raw material of producing high-grade leathercraft, be called first layer leather, with making the high-grade leathercraft higher, as goods such as summer sleeping mat, cushion, fur clothing, sofas to intensity, sweating character energy and appearance requirement; Multilayer leather such as can be divided into one by one under the first layer leather that thickness do not wait two layers, three layers are used separately as the low and middle-grade leathercrafts not high to intensity, sweating character energy and appearance requirement, as goods such as case and bag, belts.

With first layer leather production to intensity, sweating character can and during the higher high-grade leathercraft of appearance requirement, because the animal material skin can stay scar inevitably, original vestige such as fine wrinkle, the raw material skin is through the wet blue leather treating processes, the tanning dyeing course is to making leather, all can not eliminate the scar of epidermal area, original vestige such as fine wrinkle, have only and pass through the local surfaces overlay film again, color in etc. to handle and to cover vestige, but these are through overlay film, the epidermal area part of treatment process such as color in, in fact the character and the performance that have no longer had natural epidermal area, thereby finally reduced the quality of the high-grade leathercraft of producing with first layer leather, particularly at the skin summer sleeping mat, goods fields such as leather saddle, because these leathercrafts directly contact with human body, the weakness of prior art can make the corresponding local epidermal area intensity of goods inevitably, sweating character can reduce, and the chemistry of the surface attachment raw material that colors in also can bring in various degree healthy hidden danger to human body.Also has a kind of prior art, by the first layer leather of original vestiges such as scar, fine wrinkle being arranged or handles the multilayer leather respective surfaces position that the back forms smooth surface through overlay film residual, the corium that direct another piece of stickup has definite shape is made leather, and the corium that forms the local adhesive type structure with art pattern is made leather; But the constructional feature that the adhesive type structure is had, be that the corium that is used to paste is made the skin corium of removing from office reverse side, make leather relative slick epidermal area in front or overlay film layer with the corium that is stuck, the surface that forms by tackiness agent connects, this structure must have two blocks of corium and make leather joint face fibrous texture difference, connects weak weakness, because in use contacting with human body inevitably, leathercrafts such as summer sleeping mat, cushion produce regular friction, bending, make the corium leather goods of this structure, adhered layer comes off easily, and duration of service is shorter.

The utility model content

The purpose of this utility model is in order to remedy the deficiency of prior art, and the natural corium with damascene structures that original vestige such as a kind of scar of eliminating epidermal area, fine wrinkle is provided and has kept corium to make the original intensity of leather and sweating character energy, life-time service embeding layer difficult drop-off is made leather.

The purpose of this utility model is achieved in that corium makes the embedding corium that leather comprises that the matrix corium with a plurality of cavitys is made leather and polylith is bonded in the cavity, have corresponding size and a shape and make leather, and formation has the corium of local damascene structures and makes leather.Make the residual corresponding position that original vestiges such as scar, fine wrinkle are arranged of leather at matrix corium, remove epidermal area and part skin corium; Or handling the multilayer leather respective surfaces position that the back forms smooth surface through overlay film, remove overlay film layer and part skin corium, the skin corium cavity that certain plane pattern shape and certain depth are arranged, the cavity inwall all presents natural corium fabric structure, be marked with caking agent in the cavity, matrix corium is made leather and is embedded corium and make the bonding plane of leather and be skin corium; Cavity is embedded in the corium of pattern form of the corresponding size of homogeneity and makes leather, and intact epidermal area and skin corium are arranged; The corium fabric that embedding corium is made the leather reverse side fully contacts with the corium fabric of cavity inwall, by adhesive securement, forms the corium with local damascene structures and makes leather.

Because the utility model has adopted local damascene structures, the corium that is used to embed is made the skin corium of leather reverse side, make leather with matrix corium and cut off epidermal area, the skin corium cavity inwall that forms behind the part skin corium, both contacted parts are the fibrous texture of homogeneity, pass through caking agent, be intertwined to form more abundant between the fiber, more deep joint face, this structure makes two blocks of corium make closely connection of leather, make leather with the embedded corium in this part and produce summer sleeping mat, leathercrafts such as cushion, can thoroughly eliminate the scar of epidermal area, original vestige such as fine wrinkle, keep corium to make original intensity of leather and sweating character energy, the corium that embeds is made the leather life-time service and also is not easy to come off, and the corium that embeds is made leather and can be selected for use versicolor corium to make leather, cut randomly into various patterns with aesthetic feeling, select different thickness, can also make this embedded corium make leather and have the characters cut in intaglio embossing of depression or the artistic sensory effects such as characters cut in relief embossing of protrusion, improve with this embedded corium and made corium Products Quality and the class that leather is produced.
