Abstract
The invention provides a modification method of collagen fiber bundles. The collagen fiber bundles are dipped into aqueous binders and then are dried, carding and opening are carried out, and the collagen fiber bundles can become a novel fiber material capable of being used for non-woven and woven technology.
Description
(1) technical field
The invention belongs to the collagenous fibres fields, specially refer to the method for modifying that a kind of dip bonding agent strengthens collagenous fiber bundle.
(2) background technology
It belongs to a kind of new varieties in azelon collagenous fiber bundle, and collagenous fiber bundle of the present invention refers to a kind of leather glue fibrillation bundle of tanning.Mainly be taken at the skin corium of animal, it forms fibre bundle (diameter 20-150nm) step by step by protofibril (diameter 1.2-1.7nm), and this fibre bundle mutual interting in corium is woven into a three-dimensional structure WEB.Sometimes be divided into the fibre bundle of several strands thinner than coarse fiber bundle, these thinner fibre bundles are merged into another larger fibre bundle with other fine fibre bundle again sometimes, so constantly minute and close, close and minute, form in length and breadth a kind of special space network.Therefore separate from the leather of labyrinth so extremely and extract long fiber out to make in the raw material of industry be the very very difficult technology of part.The raw material of in the past making regenerated leather all adopts fairly simple crushing technology to produce, but it can adopt a kind of similar papermaking process first to make slurry then to form the sheet regenerated leather.This product can only be used as in some low-grade auxiliary material due to backward in technique.in recent years had the new breakthrough sexual development to producing the leather fiber technology, as Chinese patent, the patent No.: 20061003547.5 titles: " a kind of liquid opening machine " and number of patent application: 20101024725.1 titles: " a kind of manufacture method of leather fiber ", they have produced equal length greater than the spun collagenous fiber bundle of 16mm, although the fiber of producing with this method has reached the length requirement that weaving needs, but the various strike External Force Actings that are subject to multiple working procedure due to this fiber in the process of producing become short texture intensity low a kind of fiber that still can not spin again, this fiber is difficult to use in nonwoven or spins.With regard to require low nonwoven with fiber with regard to, in order to carry out smoothly combing, to become net, acupuncture also must mix other a large amount of traditional textile fabrics, because making goods, sneaking into of non-leather fiber lose the due valuable performance of original leather.The regenerated leather base cloth made from present state-of-the-art water thorn technology exactly is in the used time for the synthesis of leather, and it can only be as the auxiliary bottom surface material of the woven fabric that is attached to other textile materials.
In order to make collagenous fiber bundle can really be used in nonwoven or have on spinning technique, make it equally be used as raw materials for production with traditional textile fabric, must the intensity of collagenous fiber bundle be enhanced, reach the weaving requirement, this is the technical barrier that this area serious hope needs the general character of solution.
(3) summary of the invention
In order to solve the problem of collagenous fibres beam intensity, it is bonding that the present invention adopts a kind of dip bonding agent that the fiber of collagenous fiber bundle is obtained, increase the mutual cohesive force of fiber in bundle, also made up simultaneously the interfibrillar substance of loss, thereby the intensity of overall enhanced filament bundle, also make some be attached to the outer thin pinniform fiber of bundle and can be close to and control oneself, therefore reach nonwoven or spinning technique is arranged to the requirement of strength of collagenous fiber bundle.
Enhancement Method of the present invention adopts a kind of aqueous binder, and it comprises natural and artificial two kinds, with adhesive, collagenous fiber bundle is flooded, dries, unclogs and readjusts shredding.its production procedure: in filling the container of aqueous binder, drop into the collagenous fibres beam material of cotton shape and fully soak in its container, add in right amount bleeding agent in maceration extract or adopt the material to collagenous fiber bundle to carry out in advance pre-wet process, the drum extrusion machine of sending into pressing through the collagenous fiber bundle of dipping pushes, need there be one to be rubber cylinder and the content of regulating adhesive with the pressure of drum extrusion machine in two cylinders of this machine, enter drying in oven through the collagenous fiber bundle material after extruding, in order to guarantee the quality of collagenous fiber bundle, temperature in baking oven is controlled at the 50-60 Celsius temperature, circulate with pectinid in case and take away wet steam and discharge from the top exhaust hole of its case.Also can adopt the nature airing except adopting the baking oven heat drying, but their aridity need remain on moisture 15% left and right.By adhesive, they are bonded together through each filament, microfiber, fiber in the collagenous fiber bundle of this moment after above-mentioned operation, and make the pinniform fine fibre that depends on fibrillation bundle outside also be bonded to the skin of bundle.Therefore form whole closely filament bundle the intensity of fiber is improved, thereby reach nonwoven and the requirement of strength of the weaving of spinning is arranged.
After adopting the technology of the present invention, solved the technical barrier that present long stapled collagenous fiber bundle can't be weaved.Reduce simultaneously the fine fibre fuds fuddled of textile process process pinniform and improve the environmental pollution of processing site and increase output.The application of this technology just can adopt take collagenous fiber bundle as raw material existing textile technology to produce the product introduction medium and high level leather and fur products market of multiple regenerated collagen fiber innovation.This also plays a role to the leather industry resource circulating economy.
(4) specific embodiment
Embodiment 1:
Be raw material by ox-hide leather leftover pieces, produce collagenous fiber bundle through the production line that leather fiber is produced, first evenly prewetted with water spray take it as raw material, collagenous fiber bundle material after prewetting, input fills interior immersion of bucket of aqueous polyurethane emulsion, add in right amount bleeding agent in order to accelerate to soak into, collagenous fibres material after immersion takes out extruding in the drum extrusion machine of sending into, squeezing goes unnecessary adhesive to send into drying in oven, the temperature inside the box is controlled at 50-60 degree centigrade, adopts the pectinid strong cyclic in case and discharges wet steam from its casing top steam drain.Add thermal recovery Far-infrared Heating mode, get final product discharging when fiber is dried to moisture 15% left and right, through the collagenous fiber bundle material after oven dry, adopt the shredding machine that collagenous fibres are made single collagenous fiber bundle, as nonwoven or the raw material that spins is arranged, make a kind of new regenerated leather product with this material.
Embodiment 2:
This example adopts identical material and the basic identical process of upper example, wherein difference is that the aqueous polyurethane adhesive is changed into poly (vinyl alcohol) binder, producing nonwoven fabric or textiles is arranged with it through the raw material after the identical operation of upper example, the goods of making also need be through the adhesive of pyrohydrolysis except polyvinyl alcohol, namely remove the polyvinyl alcohol in the collagenous fibres goods, be formed in the pure regenerated collagen fiber leather product that does not conform to adhesive.
