Description
Technical field
The present invention relates to the dermatine material, is a kind of reducing leather base cloth and processing method thereof of utilizing Animal Skin or animal's leather collagenous fibres to make.
At present, traditional imitative leather goods have artificial leather, synthetic leather, regenerated leather.Wherein artificial leather and synthetic leather are respectively that pvc, pu are coated on woven cloth or knitted cloth or the nonwoven fabric; Regenerated leather is the leftover pieces of various leathers to be pulverized form powder by adhesive or meldable fibre adhering and pressing together.
Animal Skin is a kind of material that covers above the animal health, it is a kind of very complicated biological tissue, the animal raw hide could form leather through a series of machineries of existing tanning technology and the processing of chemistry, different types of Animal Skin has different features, but its structure all is similar to, and the main histological structure of Animal Skin is divided into:
1, epidermal area, this layer accounts for the 0.5%-5% of skin thickness according to different skin kinds, arranged by difform cell to form, and this layer will be removed together with hair in the process hides process.
2, skin corium accounts for more than 90% of whole cortex according to different its thickness of skin kind or weight, is unique processing object of existing tanning technology, and leather is processed into by skin corium in other words.Corium is compact connective, mainly form by collagenous fibres, elastomer, reticular fibre, wherein collagenous fibres account for 95%-98%, collagenous fibres are that pencil can branch, interspersed mutually interweaving in corium, crisscross, this bundle fiber is divided into several strands thinner fibre bundle sometimes, these thinner fibre bundles merge with other fibre bundle again and interweave, and form a kind of special space network.Therefore this special structure makes skin or leather have very high mechanics brute force.In addition, also contain non-fibre composition in the corium, as: blood vessel, adipose gland, interfibrillar substance and adipocyte etc.These materials major part in the process hides process is removed.
3, below the corium be hypodermis layer, it mainly is made up of braiding loose collagenous fibres and part elastomer.This layer is too loose owing to collagenous fibres weave mutually, is the discommodity in the existing leather industry.But this cortex is well to use object for the technology of the present invention.
Utilization for Animal Skin mainly is process hides at present, leather industry is an ancient industry, it is that low output with the high investment of raw material and product is a feature, has only the raw material skin of 20%-40% to change finished leather in leather-making technology, and all the other become discarded object or byproduct.Have many tailings to form discarded object in addition in the process of leather goods again, these skins or leather castoff cause serious pollution to ecological environment.
The length that collagenous fiber bundle exists in skin or leather is considerably beyond the desired length of weaving, but because collagenous fiber bundle removes braiding is tangled mutually the while and is sticked together by materials such as interfibrillar substance are bonding under the nature in skin or leather, its cohesive force is very firm, substantially exceeds the tension brute force of its fiber itself.Therefore, utilize existing shredding technology or can only be processed into very short flour by other any prior aries under nature, the moulding of can't tangling each other of this flour does not more have spinnability.Use present regenerated leather process technology above flour adhering and pressing to be formed regenerated leather together by adhesive or meldable fibre, the structure of this regenerated leather material and composition and former animal's leather all have very big difference, therefore, regenerated leather in gas permeability, hygroscopicity, tensile strength, ABRASION RESISTANCE and feel and comfortableness all not as former animal's leather, still belong to low grade products, this natural precious resources can not be made the best use of everything.But the intrinsic size of former animal's leather is restricted, particularly the size of thickness unanimity, count unanimity is subjected to stricter restriction on selecting for use, therefore former animal's leather can not be wide as, the scope of application as the textiles Crop From when making goods, and especially various leftover pieces and occurring in nature meiofauna skin kind various in style more can't be used.
Summary of the invention
The purpose of this invention is to provide a kind of utilization size, variform any Animal Skin or leather, its tailing particularly, the collagenous fiber bundle of natural woven condition is resolved into the collagenous fiber bundle that can spin length that has of the shape that looses, and having rebulid a kind of collagenous fiber bundle and branch thereof interts mutually and interweaves, crisscross solid netted braided structure, identical with the institutional framework in the former animal's leather, and have enough width as textile fabric, length is consistent with each position braiding tightness, a kind of collagenous fiber bundle reducing leather base cloth and the processing method thereof of minimal thickness unanimity are to solve existing artificial leather, synthetic leather, the shortcoming and defect that regenerated leather and leather exist.
The object of the present invention is achieved like this: this base cloth is made up of collagenous fiber bundle, and collagenous fiber bundle and branch thereof intert mutually and interweave, the solid netted braided structure of crisscross formation.
With the various leftover bits and pieces before the tanning in animal raw hide and the leather-making technology, its processing method comprises following processing step: raw material screening, dipping, depilation, liquid are separated fibre, degreasing, washing and sterilizing, dewatered drying, are mixed, shredding, combing, lapping, thorn are solid.Liquid is separated fibre and is carried out in the liquid fiber uncoiling machine.
With various animal's leathers and leftover bits and pieces thereof and waste and old leather is that its processing method of raw material comprises following processing step: raw material screening, dipping, liquid are separated fibre, washing and sterilizing, dewatered drying, are mixed, shredding, combing lapping, thorn are solid.Liquid is separated fibre and is carried out in the liquid fiber uncoiling machine.
Collagenous fibres are the diffusing shape collagenous fiber bundles that adopt at least a Animal Skin in ox, sheep, pig, horse, dog, deer, rabbit, crocodile and all animals of snake or leather and leftover bits and pieces and waste and old leather thereof to make.
This invention compared with prior art has the following advantages, and the braided structure and the animal corium of (1) this base cloth collagenous fiber bundle are extremely similar, have the ABRASION RESISTANCE identical with animal's leather, hygroscopicity, gas permeability, advantages such as anti-flammability and comfort property; (2) wide in variety, utilize different types of Animal Skin or leather can form the product of multiple different appearance characteristics, also various animals skin or leather collagen fiber can be mixed to use and learn from other's strong points to offset one's weaknesses, form various different-thickness for raw material, different in width, the various products of different counts.(3) the wide cost of raw material is low, available Animal Skin or the blanking of leather corner, the Animal Skin and the waste and old leather and fur products discarded object of not enough any use size, it is strong price advantage, (4) of many uses, the back processing of this base cloth can be adopted existing artificial leather arbitrarily, technologies such as synthetic leather form various new products, the characteristic that also can utilize collagenous fibres simultaneously is by pickling or caustic dip or immerse rapidly and make the collagenous fibres surface form gel in the hot water to restore, formation adds a kind of heavy leather of going back of bonded structure as the winding of corium, (5) this technology advanced person, particularly liquid is separated fine technology, making the bulk fiber bundle that obtains have enough length, is fiber-spinnable, arbitrarily carding, give full play to existing dry non-woven equipment and technology, make product design freely.
