Embodiment

[0025] Embodiment: a kind of two-color synthetic leather manufacture method, concrete steps are as follows:

[0026] Step 1: Wet Mixing Ingredients:

[0027] a. Stir 5-10kg of dimethylformamide and 0.5-2kg of color paste at high speed for 80-100 minutes, then filter and set aside;

[0028] b. Mix 100-200kg of dimethylformamide and 20-30kg of wood powder and stir for 20-30 minutes, then fully swell for 30-40 minutes, then add the filtered mixture in step a and stir evenly for use;

[0029] c. Add 100kg polyurethane wet-process resin to the mixture formed in step b, stir for 30-40 minutes, and defoam for 40-50 minutes;

[0030] Step 2: Wet bass production:

[0031] Squeeze the slurry formed by degassing in step 1 on the textile fabric fibers, then immerse it in an aqueous solution of dimethylformamide with a concentration of 18-22% by mass for solidification, and then go through at least one water rolling process, and then A wet bass is obtained after washing and drying;

Abstract

The invention discloses a manufacturing method of bicolor synthetic leather. The manufacturing method comprises the following steps: uniformly mixing 5-10 parts of dimethylformamide with 0.5-2 parts of color paste and filtering, uniformly mixing 100-200 parts of dimethylformamide with 20-30 parts of wood powder, and swelling, adding 100 parts of polyurethane wet-process resin in a mixture of the former two materials, mixing uniformly, de-aerating, coating on a weaved cloth fiber, soaking in 18-22% of dimethylformamide solution, solidifying, squeezing, washing by water, and drying to obtain wet-process base; uniformly mixing 100 parts of polyurethane dry-process resin, 15-20 parts of dimethylformamide, 15-20 parts of butanone, 15-20 parts of methylbenzene, 0.5-1.0 part of assistant and 3-5 parts of color powder and coating on a release paper to obtain a dry-process overlay, bonding the wet-process base, drying, separating the release paper, coating dyeing solution on the dry-process overlay, drying at 90 DEG C to 120 DEG C, washing by water, dewatering and drying to obtain a product. The bicolor synthetic leather has bicolor effect, and the product is bright in color.

Description

technical field [0001] The invention relates to a method for making artificial leather, in particular to a method for making double-color synthetic leather. Background technique [0002] Traditional artificial leather has a single color, and the surface needs to be combined with various colors and patterns through printing and other subsequent processes. When it is used, the overall sense is rigid and dull, not dazzling and bright enough. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for manufacturing double-color synthetic leather, which has simple process, double-color effect and gorgeous color. [0004] The technical scheme that the present invention adopts in order to solve its technical problem is: a kind of two-color synthetic leather manufacturing method, concrete steps are as follows: [0005] Step 1: Wet Mixing Ingredients: [0006] a. Stir 5-10kg of dimethylformamide and 0.5-2kg of c...
