Abstract
The invention relates to a method for producing leather fiber base cloth. The method comprises the following steps of: performing fiber opening on a leather block: performing physical-chemical treatment on the fragmentary leather so as to form leather fibers with lengths of 0.1 to 40 millimeters; networking the fibers: carding the leather fibers with the lengths of 0.1 to 40 millimeters through an airflow needle cloth roller, spraying different high-molecule polymers among the leather fibers or on the surfaces of the leather fibers through high temperature and high pressure spinning, and forming a network with the density of 30 to 800 grams per square meter through airflow after the leather fibers are carded in a mixed manner; and swelling a single fiber and decomposing the single fiber into a plurality of nanoscale fibers by using steam (air) thorning heat energy high speed jetting according to a high temperature and high pressure steam (air) thorning method, so that the surfaces of the fibers are softened, wherein one single fiber is thermally intersected with another single fiber so as to form the leather fiber base cloth; or softening the fibers by using water thorning heat energy and through high temperature and high pressure spunlacing so as to improve the crimpness and the self-adhesion of the fiber form and enhance the saturation, so that the leather fiber base cloth is formed. The method has a wide application range; the observent density of the leather fiber base cloth is uniform; and the physical property of the leather fiber base cloth is similar to that of real leather or is improved.
Description
Technical field
The invention belongs to hide fiber base cloth production application technical field, relate in particular to a kind of hide fiber base cloth production method.
Background technology
The goods that the staple fibre that utilizes leather leftover bits and pieces particle to extract is at present made, because of being subjected to the limitation of its fiber weak point and production technology, fail to make full use of the high-quality characteristic of former hide fiber self, make product obviously not enough aspect rerum naturas such as gas permeability, intensity, especially the following short fiber of 2mm just uses as stuffing mostly.Need to improve the comprehensive solution of manufacturing technique for this reason, to reduce the good moral character of its fiber, produce the hide fiber base cloth of excellent fine high-quality, service is good human more.
Summary of the invention
The present invention solves above-mentioned technological problems of the prior art, provides hide fiber that a kind of length can not interweave less than 2mm and hide fiber different in size to utilize innovative technology to carry out heat through air lay and interweaves and make the hide fiber base cloth production method.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of hide fiber base cloth production method may further comprise the steps:
A. skin bit is opened fibre, and the onal material is processed into 0.1mm-40mm hide fiber different in size through materialization.
B. fiber becomes net, the hide fiber that 0.1mm-40mm is different in size is air lay after air-flow card clothing rod divides comb, mix the comb back through High Temperature High Pressure spray silk at the different high molecular polymer of between each layer skin fibre or surface spray again and pass through air lay, assist into the net of 30-800 gram/weight per square meters.
C. High Temperature High Pressure vapour (gas) thorn (dry method) is crossed by the Netcom assisted of skin fibre, utilize vapour (gas) thorn heat energy and high velocity jet that single fiber is expanded and resolve into many nano-scale fibers, fiber surface is softened, and the hot interlacing of single fiber and single fiber forms the high-quality base cloth that high density, high ventilative, high strength, outward appearance do not have puneture, good hand touch; Perhaps, utilize its heat energy to make fiber softening, increase the fibre morphology crimpness and, improve its saturation degree and the base cloth of interweave formation high strength, good hand touch from viscosity by high-temperature high pressure water thorn (wet method).
As preferably, described step b between each layer skin fibre or the different high molecular polymer of surface spray, is to optimize the rerum natura of skin fibre web through high pressure spray silk.
As preferably, the high molecular polymer of described step b is one or more among polyester, modified poly ester, nylon 6, nylon 66, viscose glue, the PP.
As preferably, the net heat that the hide fiber base cloth is assisted by two-layer at least hide fiber among the described step c is handed over and is made.The net surfaces externally and internally of assisting as each layer of modification skin fibre can also be sprayed with the material of different performance through the high pressure spinning nozzle, to promote inherent performances such as its viscosity, density, elasticity, hygroscopicity, gas permeability, intensity, antibiotic, uvioresistant, sense of touch.
The base cloth that the present invention makes, because of process using advanced person's High Temperature High Pressure vapour (gas) thorn or high-temperature high pressure water thorn property make the fibre morphology improvement, fiber and the hot interlacing of fiber self-adhesion adopt the high pressure spray thread to be sprayed with the function auxiliary material and are used for modification, improve its inside and outside rerum natura, Application Areas is extensive.It is multi-field to can be used for shoemaking, clothes, case and bag, sofa, furniture, interior trim, industrial heat-insulation, filtration etc. after treatment.Every rerum natura and corium are close or raising is arranged, the finished product density uniformity, and the coiled material utilization rate reaches more than 95%.Do not produce secondary pollution in the production process, be fit to large-scale industrial production, can further utilize the leftover bits in the leather industry, form resources circulation and utilize again, help giving full play to the value of this natural precious resources of hide fiber.
The specific embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment one: the hide fiber base cloth production method may further comprise the steps: a. skin bit is opened fibre, and the onal material is processed into 0.1mm-40mm hide fiber different in size through materialization; B. hide fiber becomes net, the hide fiber that 0.1mm-40mm is different in size air lay behind air-flow and card clothing rod branch comb sprays between each layer skin fibre or surface through high pressure spray silk and passes through air lay after different high molecular polymers mixes comb, assist into the net of 30-800 gram/weight per square meters, high molecular polymer is one or more among polyester, modified poly ester, nylon 6, nylon 66, viscose glue, the PP; C. by High Temperature High Pressure vapour (gas) thorn (dry method), utilize vapour (gas) thorn heat energy high velocity jet that single fiber is expanded and resolve into many nano-scale fibers, fiber surface is softened, and the hot interlacing of single fiber and single fiber forms the high-quality base cloth that high density, high ventilative, high strength, outward appearance do not have puneture, good hand touch.Wherein the hide fiber base cloth net heat of being assisted by two-layer at least skin fibre is handed over and is made, the outside can also be sprayed with the material of different performance through the high pressure spinning nozzle in the net of assisting as each layer of modification skin fibre, to promote inherent performances such as its viscosity, density, elasticity, hygroscopicity, gas permeability, intensity, antibiotic, uvioresistant, sense of touch.
