Description
Technical field
This utility model relates to non-woven material and technical field of synthetic leather, especially relates to a kind of hydrolytic collagen superfine fiber chemical leather.
Background technology
Superfine fiber chemical leather is a kind of high-grade synthetic leather being similar to natural leather, its outward appearance and performance and natural leather are quite similar, being substitute the optimal material of natural leather at present, have good development potentiality and wide application prospect, synthetic leather industry is had revolutionary significance by its appearance.Superfine fiber chemical leather does matrix with the non-woven fabrics of three-dimensional net structure, and has polyurethane mesh and nylon (chinlon) fascicular texture of open-celled structure.In performance with configuration aspects with corium closely, feel aspect is close to natural leather, and leather body is poor without position, adapts to the needs of various industrial products for superfine fiber chemical leather.Super fiber leather is various in style, and manufacturing process is various, has better water-fast, oily and climate performance and mechanical strength than natural leather, thus is used widely in every profession and trade, it might even be possible to as the substitute products of high-grade natural leather.Regrettably, the active group contained currently as the superfine polyamide fiber of super fiber leather substrate material is less, its-COOH and-NH2It is distributed only over the end of strand, cellulosic backbone is then substantial amounts of carbochain and amido link, not having active side chain, therefore in base fabric, less active group result in steam and can not get effective transmission between fiber and the external world and absorb, thus reducing its sanitation performance.So no matter superfine fibre product is at aspects such as wearing comfort, dyeabilities, still there is a certain distance with natural leather.
Summary of the invention
In order to overcome the deficiency in background technology, the utility model discloses a kind of hydrolytic collagen superfine fiber chemical leather.
In order to realize described goal of the invention, this utility model adopts the following technical scheme that a kind of hydrolytic collagen superfine fiber chemical leather, including base layer, casing play and surface layer, described base layer includes superfine fibre nonwoven cloth base fabric and the hydrolytic collagen layer of three dimensional network structure, the two sides of described superfine fibre nonwoven cloth base fabric connects hydrolytic collagen layer respectively, adhesive connecting framework layer is passed through in the outside of described hydrolytic collagen layer, and adhesive connection table surface layer is passed through in the outside of described casing play.
For further improvement opportunity scheme, casing play described in the utility model is bundle superfine fibre layer, and described surface layer is layer of polyurethane；The polyurethane of described surface layer is distributed in the bundle superfine fibre surrounding of casing play, and polyurethane has the foaming structure of circle or aciculiform, and each abscess in described foaming structure is interconnected；Described casing play is spatially netted with surface layer entirety.
For further improvement opportunity scheme, the outside of surface layer described in the utility model is bonded with tapetum also by adhesive.
For further improvement opportunity scheme, being additionally provided with antistatic backing between surface layer described in the utility model and tapetum, described antistatic backing is conducting fiber.
For further improvement opportunity scheme, the thickness of base layer described in the utility model is 3～4mm, and the thickness of described casing play is 1.5～2.5mm, and the thickness of described surface layer is 0.2～0.8mm.
Owing to have employed technique scheme, this utility model has the advantages that the modified of superfine fiber chemical leather has been carried out exploratory development by Many researchers in recent years, its most efficient method is to manage introducing active group in superfine fiber chemical leather, and then improves its dyeability.
Gelatin is a kind of nontoxic natural biomass materials, and after hydrolysis, the collagen protein of preparation contains a large amount of active group, and hydrophilic, biocompatibility and degradability are good.Gelatin extraction in discarded shavings is out used, it is possible to economize on resources, reduces and pollute, it is achieved the recycling of discarded shavings.The present invention utilizes the hydrolytic collagen biological material extracting from leather castoff to modifiy for the compound of superfine fiber synthetic leather base cloth, chemical combination, and dexterously by a class low temperature can the aqueous PU resin of end-NCO temporary closure of deblocking as cross-linking agent, by hydrolytic collagen covalent immobilisation between the fiber fines of super fiber leather base fabric, while giving the excellent hygiene-type of super fiber leather, also give its certain plentiful pliability, colourability and biodegradable.
Hydrolytic collagen superfine fiber chemical leather described in the utility model, has excellent permeable poisture-penetrability, degradability, affinity and colourability, can be widely applied to multiple fields such as work clothes, sportswear, footwear, and application prospect is very wide.
