Embodiment 1

[0045] 1) Wet mixing ingredients: Stir 5kg of dimethylformamide and 0.5kg of color paste for 80 minutes, then filter to obtain mixture A, which is ready for use. Stir 100kg of dimethylformamide and 20kg of wood flour for 20 minutes, and fully swell for 30 minutes, then add mixture A and stir evenly to obtain mixture B, which is ready for use. Add 100kg of polyurethane wet-process resin to the mixture B formed in step b, stir for 30 minutes, and defoam for 40 minutes to obtain slurry C.

[0046] 2) Wet bass production: Squeeze slurry C on textile fibers, immerse in 18% dimethylformamide aqueous solution for solidification, then go through at least one water rolling process, and then wash and dry. After drying, wet process bass D was obtained, wherein the line speed was 18 m / min.

[0047] 3) Dry-process mixing ingredients: Mix 100kg polyurethane dry-process resin, 15kg dimethylformamide, 15kg methyl ethyl ketone, 15kg toluene, 0.5kg additives and 3kg toner and stir at high spee...

Embodiment 2

[0053]1) Wet mixing ingredients: 10kg of dimethylformamide and 2kg of color paste were stirred at high speed for 100 minutes, and then filtered to obtain mixture A, which was set aside. Stir 120kg of dimethylformamide and 30kg of wood powder for 30 minutes, and fully swell for 40 minutes, then add the mixture A and stir evenly to obtain the mixture B, which is ready for use. Add 100kg of polyurethane wet-process resin to the mixture B formed in step b, stir for 40 minutes, and defoam for 50 minutes to obtain slurry C.

[0054] 2) Wet bass production: Squeeze slurry C on textile fibers, immerse in 22% dimethylformamide aqueous solution for solidification, then go through at least one water rolling process, and then wash and dry. After drying, wet process bass D was obtained, wherein the line speed was 20 m / min.

[0055] 3) Dry-process mixing ingredients: Mix 100kg polyurethane dry-process resin, 20kg dimethylformamide, 20kg methyl ethyl ketone, 20kg toluene, 1.0kg additives an...

Embodiment 3

[0061] 1) Wet mixing ingredients: 7kg of dimethylformamide and 1.2kg of color paste were stirred for 90 minutes, and then filtered to obtain mixture A, which was set aside. Stir 110kg of dimethylformamide and 25kg of wood powder for 25 minutes, and fully swell for 35 minutes, then add mixture A and stir evenly to obtain mixture B, which is ready for use. Add 100kg of polyurethane wet-process resin to the mixture B formed in step b, stir for 35 minutes, and defoam for 45 minutes to obtain slurry C.

[0062] 2) Wet process bass production: Squeeze the slurry C on the textile fibers, immerse it in a 20% dimethylformamide aqueous solution for solidification, and then go through at least one water rolling process, and then wash and wash with water. After drying, wet process bass D was obtained, wherein the line speed was 19 m / min.

[0063] 3) Dry-process mixing ingredients: Mix 100kg polyurethane dry-process resin, 17kg dimethylformamide, 17kg methyl ethyl ketone, 18kg toluene, 0....

The beneficial effects are that: the finished product preparedusing the production method possesses metal wire base fabric characteristics, so that feather surface patterns possesses excellent third dimension performance, pattern fixing effect is excellent, andthe patterns are permanent.

Description

technical field [0001] The invention relates to memory leather and a production method thereof, belonging to the technical field of synthetic leather production methods. Background technique [0002] At present, synthetic leather products have gradually become a popular trend in the future, and synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. Now people are paying more and more attention to the aesthetics of leather. In order to make synthetic leather meet people's needs for the beauty of the leather surface, the leather will be embossed and sprayed with paint to make the surface of the synthetic leather full, bright and bright. Permeable. In the prior art, synthetic leather is mainly composed of a base fabric layer, a wet-laid base layer, and a dry-laid veneer layer. There are many technical difficulties in the embossing and spraying of synthetic leather, and the surface of the finished product is prone to low brig...
