Embodiment Construction

[0016] The present invention is a kind of colorful PU leather production process, and it comprises the following steps:

[0017] (1) Pass the non-woven fabric with a grammage of 220-230g / m² at a linear speed of 7-8m / min through a pre-coagulation tank filled with 30%-35% dimethylformamide aqueous solution; The effect of this step is a wet-laid non-woven fabric.

[0018] (2) Pass the non-woven fabric treated by the pre-solidification tank through a coating head, and coat a layer of coating material with a viscosity of 15000-20000CPS on its surface. The coating material is made of PU resin, dimethyl formaldehyde Composed of amides, fillers, and colorants, the weight ratio of which is 100:65-75:10-15:2 PU resin: dimethylformamide: filler: colorant; the colorant can be selected according to production needs Or a combination of pigments of multiple colors.

[0019] (3) The non-woven fabric treated in step (2) is sequentially solidified and washed through the coagulation tank and t...

Abstract

The invention discloses a colorful PU leather production process. The colorful PU leather production process comprises the following steps: firstly, preparing a wet-type semi-finished product, enabling a non-woven fabric to pass through a pre-solidifying tank, then coating the surface of the non-woven fabric with a layer of coating material, then successively carrying out curing and water-washingtreatment, and then drying to obtain a wet-type semi-finished product; secondly, successively coating the surface of release paper with a shell fabric and a bottom material, after pre-heating, pressing the bottom material and the wet-type semi-finished product, and then drying to obtain a semi-finished product; and finally, coating the semi-finished product through a rolling head with a coating material having flickering pieces, and then drying to obtain a finished product. Base cloth is subjected to special pre-solidification treatment and coating treatment through the coating head, the prepared base cloth has high resilience characteristic and folding resistance, after the base cloth is compounded with the shell fabric and the bottom material, the leather can recover the state before deformation after external force on the leather disappears, and by roll coating of a special material, the leather has dazzling surface and a glossy bright effect.

Description

technical field [0001] The invention relates to a production method of colorful PU leather, and the produced leather is used in fields such as leather shoes, leather clothes, or sofa products. Background technique [0002] The application of synthetic leather in the fields of clothing, sports shoes, sofas and bags is becoming more and more extensive, which to a large extent makes up for the scarcity of sports leather and the impact on related manufacturing industries. Now many manufacturing industries such as shoes, women's Bags use a lot of flickering accessories, but the current flickering of the accessories is not very good, and cannot fully meet the needs of the industry. Contents of the invention [0003] The object of the present invention is to provide a kind of bright-coloured PU leather production method with glittering bright effect. [0004] The technical scheme adopted in the present invention is as follows: [0005] The present invention is a kind of colorfu...
