Embodiment Construction

[0052] Below the embodiment of the present invention is described further:

[0053] A garment leather production process, the garment leather production process includes: the first stage: using a wet production line to process the base fabric into Base: (1), preparing polyurethane slurry; (2), selecting the base fabric, the base fabric The material is preferably knitted fabric, and the base fabric is infiltrated with water; (3), the base fabric is ironed and semi-dried with a normal temperature ironing wheel; (4), the above base is arranged in polyurethane slurry for wet film formation; (5) ), the product after film formation is washed with water to remove the residual DMF, and the semi-finished product is made after finalizing and drying. The production line speed is controlled at 18-25m / min, preferably 22m / min,

[0054] The second stage: dry film to process the Base into leather: (1), color-matching the polyurethane resin; (2), apply the color-matched polyurethane resin on t...

Abstract

The invention relates to a clothing leather manufacturing process and a formula thereof. The process includes the steps of: 1) process on a base cloth to obtain a base through a wet-method production line: soaking the base cloth in water, ironing the base cloth to semi dry through an ironing wheel, performing wet-method film forming to the base cloth in polyurethane slurry, and water-washing a product with film formed to remove residual DMF, and shaping and drying the product to obtain a semi-product, wherein a composition in the step 1) includes: DMF, a flatting agent, a defoamer, a white color paste, light calcium, paper pulp powder and wet-method resin; 2) dry-method film lamination to process the base into leather: coating a release paper with toned polyurethane resin and drying the release paper to semi dry, and laminating the release paper with the base, and drying and stripping the release paper, wherein a composition in the step 2) includes: DMF, butanone, white powder, dry-method resin and a waterproof agent; and 3) later processing treatments: performing printing treatment with a three-processor and priming aqueous treatment, performing embossment and surface aqueous treatment, kneading the leather to form grains, and performing finish product inspection, wherein a composition in the step 3) includes: a priming aqueous treatment agent, aliphatic resin and a crosslinker. The manufacturing process and the formula simplify procedure, reduce period, reduce cost and improve production efficiency.

Description

technical field [0001] The invention relates to the field of leather production, in particular to a garment leather production process and its formula. Background technique [0002] Nowadays, leather products of various designs and colors can be seen everywhere in daily life, such as interior decoration, sofa fabrics, car interiors, clothing, shoes and bags, etc. People often think that these products are made of natural leather, but in fact they are not. A sizable share of products is occupied by synthetic leather. The raw materials for synthetic leather in the existing market are seriously wasted, and the production efficiency is low and the cost is high. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the present invention provides a garment leather production process and its formula, which mainly solve the problems of material waste, high cost and low production efficiency in the existing garment leather production...
