Problems solved by technology

[0002] At present, the products made of short fibers extracted from leather scraps are not able to make full use of the high-quality characteristics of the raw leather fibers due to the short fibers and the limitations of the production process, which makes the products obviously insufficient in terms of air permeability, strength and other physical properties. Especially short fibers below 2mm are mostly used as fillers

Embodiment 1

[0013] Embodiment 1: the production method of leather fiber base cloth comprises the following steps: a. skin block is opened fiber, and broken leather material is processed into the leather fiber of 0.1mm-40mm length through physicochemical treatment; b. leather fiber is netted, and 0.1 mm-40mm leather fibers with different lengths are combed by air flow and card cloth sticks, then air-laid into a web, and then sprayed with different high molecular polymers between layers of leather fibers or on the surface of each layer of leather fibers and combed by high-pressure spraying, and then air-laid to form a web. 30-800 g / m2 weight net, the high molecular polymer is one or more of polyester, modified polyester, nylon 6, nylon 66, viscose, PP; c. through high temperature and high pressure steam (gas ) stabbing (dry method), using steam (gas) stabbing heat energy to spray at high speed to make a single fiber expand and decompose into multiple nano-scale fibers, the surface of the fib...

Embodiment 2

[0015] Embodiment 2: the production method of leather fiber base cloth comprises the following steps: a. skin block is opened fiber, and broken leather material is processed into the leather fiber of 0.1mm-40mm length through physicochemical treatment; b. fiber is netted, and 0.1mm - 40mm leather fibers of different lengths are combed by air-flow needle cloth sticks, and then sprayed with different high-molecular polymers between layers of leather fibers or on the surface through high-pressure spraying. A net with a weight of square meters, the polymer is one or more of polyester, modified polyester, nylon 6, nylon 66, viscose, and PP; c. Through high temperature and high pressure spunlace (wet method), use Hydroentanglement can soften the fiber, increase the curl and self-viscosity of the fiber, increase its saturation and interweave to form a base fabric with high strength and good hand feeling. Among them, the leather fiber base cloth is made of at least two layers of leath...

Abstract

The production method of the leather fiber base cloth includes the following steps: opening the leather block, and physically and chemically treating the shredded leather material into leather fibers with different lengths of 0.1mm-40mm; After being carded by air-flow card cloth sticks, spraying different high-molecular polymers between layers of leather fibers or on the surface through high-temperature and high-pressure spraying, and then air-laid to form a net with a weight of 30-800 grams per square meter; The fiber-assisted web is punctured by high-temperature and high-pressure steam (gas), and the single fiber is expanded and decomposed into multiple nano-scale fibers by using the heat energy of the steam (gas) thorn at a high speed. The surface of the fiber is softened, and the heat exchange between the single fiber and the single fiber The leather fiber base cloth is formed by intertwining, or through high temperature and high pressure spunlace, the fiber is softened by the heat energy of the spunlace, the curl degree and self-viscosity of the fiber shape are increased, the saturation is increased and the leather fiber base cloth is interwoven. The invention has wide application fields, uniform apparent density, and various physical properties are similar to those of corium or improved.

Description

technical field [0001] The invention belongs to the technical field of production and application of leather fiber base cloth, and in particular relates to a production method of leather fiber base cloth. Background technique [0002] At present, the products made of short fibers extracted from leather scraps are not able to make full use of the high-quality characteristics of the raw leather fibers due to the short fibers and the limitations of the production process, which makes the products obviously insufficient in terms of air permeability, strength and other physical properties. Especially short fibers below 2mm are mostly used as fillers. For this reason, it is necessary to improve the comprehensive solution of the manufacturing process, to restore the excellent character of its fiber, to produce a high-quality leather fiber base cloth with excellent fiber quality, and to better serve human beings. Contents of the invention [0003] The present invention mainly sol...
