Problems solved by technology

[0004] The characteristics of natural leather are isotropic, and the synthetic leather base fabric imitates the base structure of natural leather. The cloth is relatively low, and the vertical and horizontal ratio is relatively large, so it still cannot meet the requirements of high-grade leather base cloth

preparation example Construction

[0024] A kind of preparation method of high-performance uniform leather base cloth that the present invention relates to, comprises the following steps:

[0025] ① Preparation of non-woven fabric layer: the non-woven fabric layer is made of 70-100wt% recycled polyester fiber and 0-30wt% Dahua polyester staple fiber as raw materials, and is mixed and opened, carded into a net, laid and two layers A non-woven fabric layer is formed after needling; the linear density of the regenerated polyester fiber is 1.5-4D, and the fiber length is 38-76mm; the linear density of the Dahua polyester staple fiber is 1.4-3D, and the fiber length is 38-51mm.

[0026] For the opening and mixing process: fully open and mix the above-mentioned regenerated polyester fibers and Dahua polyester staple fibers to make them evenly mixed. In order to improve the mixing effect, manually mix the cotton and adjust the humidity at a certain temperature and humidity in advance, which can reduce fiber damage and...

Embodiment 1

[0038] The invention relates to a preparation method of a high-performance uniform leather base cloth, which uses 85% by weight of recycled polyester fiber and 15% by weight of Dahua polyester staple fiber as raw materials. Among them, the fineness of recycled polyester fiber is 2.5D, the fiber length is 51mm, the fineness of Dahua polyester staple fiber is 1.5D, and the fiber length is 51mm. The warp density of the woven fabric is 65-75 threads / in, and the weft density is 37-40 threads / in.

[0039]During production, the fiber raw materials are firstly opened and mixed, and then the fibers are fed into the carding system through the fiber feeding system, the vibrating cotton box or the pneumatic cotton box or the combination of the two boxes, and the fiber is carded into a web, and then passed through the web-laying machine. Carry out repeated overlapping to the required number of layers or gram weight of 250-270 grams per square meter. High-performance uniform leather base f...

Embodiment 2

[0045] The invention relates to a high-performance uniform leather base cloth, which uses 85% regenerated polyester fiber 2.0D×51mm and 15% regenerated polyester fiber 3.0D×51mm as raw materials, and the warp density of the woven cloth is 70-75 pieces / in, the weft density is 40-45 threads / in.

[0046] During production, the fiber raw materials are firstly opened and mixed, and then the fibers are fed into the carding system through the fiber feeding system, the vibrating cotton box or the air pressure cotton box, and the fibers are carded into a web, and are repeatedly overlapped to the desired The number of layers or gram weight is 250-270 g / m2. High-performance uniform leather base fabrics were prepared by 5 needling machines and 9 needle-plate needling machines. The fiber web is preliminarily formed into a fiber mat through barbs and positive punctures.

[0047] The frequency and depth of the first needling are 550-650r / min, 12-14mm respectively, and the frequency and de...

Abstract

The invention discloses a preparation method for high-performance uniform leather base cloth. The preparation method comprises a first step of preparing a non-woven cloth layer; a second step of compositing the prepared non-woven cloth layer and a woven cloth layer; and a third step of performing reinforcement and hot rolling treatment, wherein in the first step, 70-100wt% of regenerated polyester fibers and 0-30wt% of chemical fiber polyester staple fibers serve as raw materials and undergo mixed opening, carding, lapping, primary needling and secondary needling to form the non-woven cloth layer, the linear density of the regenerated polyester fibers is 1.5-4D, the fiber length of the regenerated polyester fibers is 38-76mm, the linear density of the chemical fiber polyester staple fibers is 1.4-3D, and the fiber length of the chemical fiber polyester staple fibers is 38-51mm; and in the second step, the woven cloth layer is selected, is compositely connected with the non-woven cloth layer prepared in the first step through a needling process and is made of polyester yarn, the warp density of the woven cloth layer is 65-85 pieces / in, and the weft density of the woven cloth layer is 35-50 pieces / in. The characteristic of large vertical and horizontal strength ratio of non-woven cloth and the characteristic of small vertical and horizontal strength ratio of woven cloth are combined by the preparation method, so that the prepared leather base cloth has unique characteristics of the non-woven cloth and the woven cloth and has uniform vertical and horizontal breaking strength and breaking elongation rate performance.

Description

technical field [0001] The present invention relates to the field of leather base cloth, more specifically relates to a kind of preparation method of high-performance uniform leather base cloth, and the leather base cloth that it makes has vertical and transverse breaking strength and breaking elongation ratio within 1:1.1, blasting High strength, smooth surface and good stiffness. Background technique [0002] In the production of synthetic leather, one of the keys to requiring synthetic leather to have a unique style and excellent performance is the choice of base fabric. The excellent performance and stability of the base fabric play an important role in the strength and stability of the final product. It requires the base fabric to have good vertical and horizontal To strength and solution permeability. [0003] At present, woven fabrics, knitted fabrics and nonwoven fabrics can meet these requirements and can be used as base fabrics. However, non-woven fabrics are arr...
