The invention relates to the technical field of the production of leather, and particularly relates to a processing method of cattle-hide fibers. The processing method of the cattle-hide fibers comprises the following steps: a. primarily splitting fibers, namely, cutting a pure cattle-hide leftover material in an irregular size into square small blocks of 1cm*1cm in a regular size; b. secondarily splitting the fibers, namely, changing the small-blocks of cattle hide in regular sizes into crude fibers with the length of 0.8cm to 1cm; c. tertiaryly splitting the fibers, namely, preparing fine fibers by utilizing the crude fibers, controlling the fiber length of the cattle-hide fiber in the range of 3mm to 7mm, and controlling the fineness at 0.3mm+/-0.05mm. By adopting the processing method, waste is converted into treasure; the leftover broken material of the authenticate leather can be adequately utilized, no chemical additive is added when in production, the product is environment-friendly, and the requirement of the international market for the leather can be met.
Description
Technical field
The present invention relates to leather production technical field, particularly a kind of processing method of kraft fibers.
Background technology
Along with growth in the living standard, the application of leather and fur products is increasingly extensive, grows with each passing day both at home and abroad to the demand of leather material.Leather permeability, water imbibition, elasticity are all better, the advantages such as soft handle, but cost is higher.The a large amount of offcuts produced in leathercraft production process are not fully recycled, and a part only lets alone contaminated environment as waste material, and another part is used as his use by lawless person, as prepared medical gelatin or producing capsule.The conventional treatment method of discarded cladding is: prepare medical gelatin or capsule by industry after leather leftover pieces grinder mill powdered, also have as animal feed, the direct burning disposal of most leftover pieces.How turning waste into wealth, make full use of the offcut of leather, is the Research Challenges of the current industry.The utilization again of leather leftover pieces often needs to process it, to carry out combining or Application of composite with other materials, conventional processing method can not meet or can not reach the object with other materials Application of composite.
Summary of the invention
The invention provides a kind of processing method of kraft fibers, the method meets the kraft fibers of production requirement for providing, kraft fibers size uniformity, fibre length and fineness degree that the method obtains all meet the requirement with composite for base fabric, thus further produce ox embryo cloth product.
The technical solution adopted for the present invention to solve the technical problems is:
A processing method for kraft fibers, comprises following three road fibrillation step: a, first fibrillation, the fritter that 1cm × 1cm that the pure ox-hide leftover pieces of irregular size are cut into regular size is square; B, second fibrillation, make the fritter ox-hide of regular size change the crude fibre that length is 0.8cm-1cm into; C, the 3rd road fibrillation, fine fibre made by crude fibre, makes the fibre length of kraft fibers control within the scope of 3-7mm, and fineness degree is 0.3 mm ± 0.05mm.The kraft fibers that this method obtains can meet the requirement that papermaking becomes net and water thorn compound, and as fiber is oversize, papermaking wet-laying just can not ensure with regard to the uniformity, and fiber is too short, stings with nonwoven water distribution the requirement that combined strength bination just can not reach leather.Further, according to inventor's repeatedly experience of obtaining of compound, fiber is too thin, and fibrous elasticity just can not ensure, the too thick and non-woven fabric compounded intensity of fiber can not ensure.
As preferably, the method is specific as follows:
A, clean pure ox-hide leftover pieces are through preliminary treatment, its moisture content is made to reach 60-80%, enter first fibrillation, the blade of High Rotation Speed makes the material in sieve plate be divided into fritter ox-hide, selection by winnowing deslagging, discharge size inhomogenous particle, to obtain the fritter ox-hide square in 1cm × 1cm of size uniformity after guaranteeing first fibrillation;
B, square fritter ox-hide are through atomization process, and moisture content reaches 60-80%, enters second fibrillation, selection by winnowing deslagging, discharge size inhomogenous particle, to obtain the ox-hide crude fibre of length in 0.8-1cm scope of size uniformity after guaranteeing second fibrillation;
C, ox-hide crude fibre are through atomization process, and moisture content reaches 60-80%, enters the 3rd road fibrillation, selection by winnowing deslagging, and discharge the inhomogenous particle of size, obtaining fibre length is 3-7mm, and fineness degree is the kraft fibers of 0.3 mm ± 0.05mm.
As preferably, described preprocessing process is the drying and processing of spraying process or less than 50 DEG C, and the selection of preprocess method is determined according to the moisture content of pure ox-hide raw material.
As preferably, sieve plate is the meshed stainless steel cylinder of band, and the screen deck net hole dimension of first fibrillation is 10mm × 10mm, and the screen deck net hole dimension of second fibrillation is 10mm × 7mm, and the screen deck net hole dimension of the 3rd road fibrillation is 15mm × 1.2-1.5mm.
The invention has the beneficial effects as follows: kraft fibers processing method provided by the invention, turn waste into wealth, make full use of the offcut of leather, during production, do not add any chemical addition agent, Product Green environmental protection, the requirement of international market to leather can be met.The obtained kraft fibers elasticity of the method is better, size is homogeneous, can use paper process wet-laying, to become after net can with nonwoven water distribution acupuncture manipulation laminating production leather substrate, papermaking can be made into kraft fibers paper for all kinds of field after becoming net oven dry.
