Description

A kind of device that ultrashort kraft fibers are extracted from ox-hide leftover pieces

Technical field

It the utility model is related to leather fiber technical field, and in particular to a kind of to extract ultrashort ox-hide fibre from ox-hide leftover pieces The device and method of dimension.

Background technology

With the raising of modern standard of living, leather and fur products with its it is attractive and durable and it is deep liked by consumers in general, All commercially occupy very big share with leatherwork clothes, shoes and hats, furniture, stomacher, automobile decoration material etc., it is right both at home and abroad The demand of leather material is increasingly to increase severely, and leather permeability, water imbibition, elasticity are preferable, the advantages that soft handle, but It is that cost is higher, caused a large amount of offcuts do not recycle fully in leathercraft production process, and ox-hide leftover pieces are Inevitable discarded object in ox-hide product generating process, and ox-hide is mainly mutually woven by the collagenous fibres of beamforming and microbeam type, phase The reusing for leather leftover pieces such as mutually winding composition, true ox-hide generally require to handle it, but existing by leather side Many defects and deficiency be present in the method for corner material reprocessing processing.

Chinese invention patent application (201110146644.8), discloses a kind of preparing cowhide fiber yarns from cowhide leftover materials Method, this invention describes ox-hide leftover pieces are screened successively, color separation, impurity elimination, it is expanded and softening, extruding, repeat soak With extruding, hammering make suede, final finishing, pull loose, dry after obtain length be 15-50mm, ox-hide that fineness is 0.5D-2.2D fibre Dimension, the kraft fibers after drying are obtained into described kraft fibers yarn by combing, drafting, spinning process successively.In fiber Need to use chemical immersion process in extraction process, contain 5-15 kilograms of bleeding agent (sulfonation in the processing aqueous solution per double centner Succinate sodium salt, oleoyl amino acid sodium or straight-chain fatty alcohol APEO etc.), 3-13 kilograms of swelling agent (aromatic hydrocarbon With the compound of the compound or phenols and higher aliphatic APEO of higher aliphatic APEO) and 0.5-3 Kilogram sodium hydroxide, and need repeatedly immersion.Such complex treatment process and the useless discharge of liquid can be increased, it is difficult to meet environmental protection It is required that.

Chinese invention patent application (200410034435.4), disclose a kind of animal's leather collagen yarn and its producer Method, its core technology are mainly to be mixed using the fibrous raw material of different weight ratio, highlight animal leather collagenous fibres Accounting be 1-100%, textile fabric 0-99%, kraft fibers fiber yarn forming mechanical performance can be improved by blending.Should Patent has simply generally referred to the size of yarn ratio, and the specification of fiber, such as length, fineness etc. are not made It is bright, and it also will pass through solution immersion, washing etc. before solution is fine to leather material and produce waste liquid, equally be unfavorable for environmental protection.

Chinese invention patent application (201410767182.5), disclose a kind of processing method of kraft fibers, its method It is including three fibrillation processes, ox-hide leftover pieces are preprocessed, its moisture content is reached 60-80%, first of fibrillation, using height The blade of speed rotation makes the material in sieve plate be divided into fritter ox-hide, and selection by winnowing deslagging, obtain size uniformity is in 1cm × 1cm side The fritter ox-hide of shape, kraft fibers of the length in 3-7mm are finally given through second, third road fibrillation and selection by winnowing deslagging；Middle promulgated by the State Council Bright patent (201510318230.7) discloses a kind of dry and wet joint networking combination process, wherein by the pure ox of cleaning before networking Skin (natural, no added) leftover pieces use is made kraft fibers by fiber opening process grinding, and it is 2-8mm to control fibre length, though The kraft fibers gone out using ox-hide leftover pieces processing within 2-10mm, but its are disclosed in right two patent documents It is not related to polishing or processing mode and the method that the ultrashort kraft fibers can be spinned of specific kraft fibers.

Chinese patent (CN203021703U) discloses cortex material fiber uncoiling machine in a kind of water, and the fiber uncoiling machine includes making onal The aqua storage tank and Bearded-needle knitted cloth roller that matter material suspends in water, three working rolls are horizontally disposed and surround Bearded-needle knitted cloth roller appearance Face top side, fin or billhook are provided with three working roll outer surfaces, and the patent application is equally to need to soak cortex material Duck in drink, between the cortex material in water is transferred into the working roll of relative rolling by Bearded-needle knitted cloth roller, by being arranged on The triangle fin of work roll surface is torn into threadiness after cortex material is caught on.

Japan Patent (clear 62-21808A) discloses the device of a kind of softening and fibrillation leather fiber, and the device includes more To roller pair setting up and down, have in the up-down rollers of the contact surface up and down of which part roller pair or on lower roll along roller axial direction not Uniform groove.

Chinese patent (CN2905832Y) discloses a kind of animal's leather fiber-opening apparatus, and it includes frame, and frame front is set There is the flat curtain of feeding, dust cage is provided with frame, fibrillation licker-in is provided between dust cage and the flat curtain of feeding, thorn is provided with licker-in bottom Roller bottom drain, licker-in bottom drain top are the arcwall faces being engaged with licker-in, are fed roller in anterior be provided with of licker-in, feed roller is divided into There is dish plate, the upper surface of dish plate is the arcwall face being engaged with feed roller, is set between feed roller and the flat curtain of feeding There are a pair of feed rollers being arranged above and below, discharging hired roughneck is provided with dust cage rear portion, the device can process the dynamic of 10-45mm length Thing hide fiber, but its need also exist for before processing to Animal Skin carry out structure expansion pre-treatment, and the device mainly according to Leather shredding is attracted to dust cage into the few fibers of fibre and finally shelled by hired roughneck by the high speed rotation by licker-in into fibre, only shredding Blanking is taken, also has the bottom drain that part is not fallen into below licker-in by the fritter Animal Skin of fibrillation, the fibrillation of its ox-hide leftover pieces utilizes Rate is low.

Understood according to above-mentioned prior art：Kraft fibers are obtained using chemical method, although longer fiber can be obtained, But it is strictly limited because processing method is difficult to meet the requirement of environmental protection in actual production；Ox-hide is obtained by non-woven mode Fiber base cloth, although reducing the requirement to fibre length to a certain extent, its fabric vertical, horizontal strength is not often up to To the requirement of finished product；Kraft fibers scribbled is prepared by mixing fine technology, although kraft fibers fiber yarn forming machine can be improved Tool performance, but pertinent literature has only generally referred to scattered fine mixed proportion, the technology contents description to practice is more fuzzy, and It also will pass through solution immersion, washing etc. before solution is fine to leather material and produce waste liquid, be unfavorable for environmental protection；It is existing from ox-hide Or the device or equipment majority of other animal hide offal extraction leather fibers are intended to before fibrillation to its leather material Solution immersion is learned, makes its expansion or in a liquid fibrillation, easily produces waste liquid, be unfavorable for environmental protection, although in the prior art There are the open kraft fibers obtained using physics fibrillation, Ginding process within 2-10mm, but it is not directed to specific grinding and opened Fine equipment or it is low to leather leftover pieces fibrillation utilization rate.
