Abstract
The invention discloses a manufacturing method for hydrolysis-resistant clothing leather. The method comprises the steps of mixing 5-10 kg of dimethyl formamide and 0.5-2 kg color paste uniformly; filtering the mixture; adding 100-120 kg of dimethyl formamide and 20-30 kg of wood powder to the above mixture, stirring uniformly and swelling; adding 100 kg of a polyurethane wet resin, stirring uniformly, defoaming and coating the obtained mixture on the textile fabric fiber; immersing in a solution of 18-22% dimethyl formamide to make the mixture solidified, squeezing water, washing with water and drying to obtain a wet base; mixing 100 kg of polyurethane dry resin, 10-20 kg of dimethyl formamide, 10-15 kg of butanone, 15-20 kg of toluene, 0.5-1.0 kg of an auxiliary agent and 3-5 kg of a toner uniformly and coating the obtained mixture on release paper to obtain a dry veneer; adhering the wet base to the dry veneer, drying, separating from the release paper, washing with a water graining machine and drying. The obtained product has the effects of hydrolysis resistance, cold resistance and folding resistance, and can effectively prolong service life of the leather.

C. 100kg polyurethane wet method hydrolysis resin is joined in the mixture that step b forms, stirred 30～40 minutes, deaeration 40～50 minutes;
Step 2: the wet method bass is produced:
With in the step 1 the slurry that forms of deaeration be coated with and scrape on the woven fabric fiber, immerse again mass percentage concentration and be in 18～22% the dimethyl formamide aqueous solution and solidify, then through at least one squezzing operation, wash again with drying after obtain a kind of wet method bass;
Step 3: dry mixed batching:
High-speed stirred after 100kg polyurethane dry method hydrolysis resin, 10～15kg dimethyl formamide, 10～15kg butanone, 15～20kg toluene, 0.5～1.0kg auxiliary agent and 3～5kg toner mixed, mixing time 10～15 minutes is to stirring;
Step 4: dry method veneer:
The dry method slurry for preparing in the step 3 is coated with to scrape on the release liners with the flower type, forms the dry method veneer, then be to be adhered on the dry method veneer under 90～110 ℃ the condition in temperature with the wet method bass in the step 2 by adhesive, separate through super-dry heel release liners;
Step 5: rub line:
20-50M is separated rear product, put into the water boarding machine and washed 10～30 minutes, take out also oven dry of dehydration, bake out temperature is controlled at 90～120 ℃.
As a further improvement on the present invention, dimethyl formamide and mill base high-speed stirred 90 minutes among the described step a.
As a further improvement on the present invention, use 240 order nylon wires that the mixed liquor of dimethyl formamide and mill base is filtered among the described step a;
B. with 100～120kg dimethyl formamide and 20～30kg wood powder mix and blend 30 minutes, then abundant swelling 35 minutes then adds and filters good mixture among the step a and stir stand-by;
C. 100kg polyurethane wet method hydrolysis resin is joined in the mixture that step b forms, stirred 40 minutes, deaeration 45 minutes.
As a further improvement on the present invention, step 3: dry mixed batching:
High-speed stirred 15 minutes was to stirring after 100kg polyurethane dry method hydrolysis resin, 10～15kg dimethyl formamide, 10～15kg butanone, 15～20kg toluene, 0.5～1.0kg auxiliary agent and 3～5kg toner mixed.
The invention has the beneficial effects as follows: the present invention effectively prolongs its service life by using polyurethane wet method hydrolysis resin and polyurethane dry method hydrolysis resin to reach the effect that artificial leather itself has hydrolysis, cold-resistant, folding.
