Description
Technical field
The present invention relates to the hemp packing goods, especially a kind of is the main goods of being processed into as filler with collagenous fibres.
Background technology
Employed stuffing product is a lot of in people's daily life, as cotton-wadded quilt, cotton-padded mattress, pillow, mattress, toy, automobile cushion, sofa, brassiere etc., these goods all be by various fabrics as lining or in the material, interlayer or center are filled with natural fiber or the chemical fiber filler is made.
The filler that prior art is used comprises hemp packing or other fillers.Wherein hemp packing can be divided into two kinds of wadding material filler and material class fillers according to form again.Wadding class filler is meant natural fiber or the chemical fiber without weaving processing.They do not have fixed shape, are in loose condition (of surface).As cotton-wool, silk flosssilk wadding, eider down etc.Material class filler generally is will have the natural fiber of spinnability or chemical fiber by nonwovens process to be processed into and to have soft, even, fixing lamellar morphology, can with lining and/or in material cutting simultaneously, as " gum sprayed cotton ", " hot melting wool ", " acupuncture cotton " etc.All there is different shortcomings in existing fiber, and as natural fiber price height, resource-constrained, the chemical fiber warmth retention property is poor, especially poorer than the cold district warmth retention property.
Utilization to animal skins mainly is process hides at present, in leather-making technology, owing to the raw material skin all exists various defectives as scalding note, fertile wrinkle, bur scratch etc. and other multiple reasons, finally have only the raw material skin finishing cut finished leather of 20%-40%, all the other have all become tailing.In addition, in the leather goods course of processing, can produce a large amount of offcuts again, make this resource very low at the degree of utilization in process hides field.Therefore, annual a large amount of leather limits, following, the angle material of producing of China's leather processing industries, these leather wastes industrial except that being used as low value-added product such as processing regenerated leather, industrial gelatine, protein feed on a small quantity, all the other major parts go out of use, and more do not have the development and utilization of actv. top grade.
Leather is after passing through a series of physical mechanicals and chemical treatment by the skin that animal peels on one's body, to become leather by tanning, forms the i.e. material of fixing not perishable damage of the anti-mechanical action of anti-bacterial action.Before the tanning is skin or rawhide.Skin of a great variety is a kind of very complicated biological tissue.But its structure is close, all is to be made of skin covering of the surface, skin corium and hypodermis.Surface layer thickness accounts for 0.5-5%, is to be arranged by difform cell to form, and skin corium thickness accounts for more than 90%, is compact connective, and mainly elastic fibre and the reticular fibre braiding by collagenous fibres and trace forms.Wherein collagenous fibres account for 95-98%, and the finished product leather is processed into by corium.And what remain in the corium is exactly collagenous fibres.The finer structures of collagenous fibres is done following arrangement: peptide chain-protofibril-fiber yarn-fibril-microfiber-fiber-fibrous bundle, the notion of the collagenous fibres of indication of the present invention is meant collagenous fiber bundle.Hypodermis layer mainly contains braiding to be formed than the elastic fibre of pory collagenous fibres and trace, is the open texture that connects each other between animal skins and the animal body, and skin is peeled by the driven thing of this one deck on one's body.Because therefore loose, the random form of the collagenous fibres of hypodermis layer braiding is eliminated in curriery, but be good raw material for the present invention.The natural braiding structure form of collagenous fibres in corium is very special: be to be divided into several strands thinner fibrous bundle sometimes with thicker fibrous bundle, these thinner fibrous bundles are merged into another bigger fibrous bundle with other fibrous bundle again sometimes.So constantly divide and close, close and divide, crisscross, be not compiled into a kind of special space network with knowing the beginning and the end, make leather have very high mechanics brute force.In the middle of the space of the fibrous bundle of animal skins, fill a kind of gelatinoid, be called interfibrillar substance.It is mainly by albumin, globulin, sticking egg is constituting with class lipoprotein and glucide, interfibrillar substance viscosity is very high, but lubricate under hygrometric state, under the normality drying regime, solidify hardening, being bonded together tightly of the collagenous fibres in the leather, most interfibrillar substance is removed though determine in the tanning production, but still have part residual, processed that tannin is distributed between the collagenous fibres in the journey in addition in tanning, in the dry run in leather-making technology, because the evaporation of moisture, the tannin molecular change is big, the bridged bond that causes adding produces, again because the capillary pressure function in dry run makes the capillary tub bending, contraction makes the collagenous fibres that are woven together take place further bonding.Cohesive force between the collagenous fibres in the leather under the natural seasoning state is very big, surpasses the tensile strength of collagenous fibres.The collagenous fibres density of the bonding point in the leather under normal conditions reach every interval 1-2 millimeter many places are just arranged.Therefore, any shredding equipment that uses prior art carries out to the dry state leather that fiber decomposes or shredding all can be broken collagenous fibres and formed powder or the card clothing of opener is damaged under the natural seasoning situation.
Chinese invention patent application 92103486 once disclosed a kind of with leather consider to be worth doing broken through simply pulverize and fall soft technology after prepare the method for skin chenille article as weighting material.But the technology of this method is simple, and made weighting material is exactly under the situation of dry state leather to be pulverized the formation micro scurf, rather than leather fiber.And this method does not solve the key issue of the above-mentioned mutual dung of mentioning of collagenous fibres.Therefore this technology can only finally form powder with leather, is the inevitable outcome of this method.This method can not prepare spendable fibrous weighting material goods in practice, does not possess exploitativeness.This patent application has been looked and has been removed, and has also proved this point.
