Embodiment
[0024] Embodiment: a kind of hydrolysis-resistant garment leather production method, concrete steps are as follows:
[0025] Step 1: Wet Mixing Ingredients:
[0026] 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;
[0027] b. Mix 100-120kg 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 later use;
[0028] c. Add 100kg of polyurethane wet-process hydrolysis-resistant resin to the mixture formed in step b, stir for 30-40 minutes, and defoam for 40-50 minutes;
[0029] Step 2: Wet bass production:
[0030] 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 o...
