Embodiment 1
[0022] 1. The non-woven fabric is infiltrated with 4050 wet-process polyurethane of 3000CPS in the impregnation tank to obtain the rough surface, and the other layer is fully infiltrated by pressing 5020 wet-process polyurethane of 9000CPS through multiple pressure rollers in the impregnation tank to obtain dense Floor.
[0023] 2. The high-solid imitation leather base fabric was overflow dyed at 105 degrees for 70 minutes to obtain the dyed base fabric;
[0024] 3. Dry the dyed base cloth, and use 240-mesh sandpaper when the dried base cloth is buffed and brushed;
[0025] 4. The base cloth after buffing and brushing is soaked in the oil tank by impregnation, the pressure and gap of the pressing roller are adjusted to control the liquid-carrying rate at 45%, and it is dried in an oven at 120 degrees. The softener is Nanjing Gutian 890RZ, and the proportion of softener used is 15%;
[0026] 5. Finally, mechanically knead the soft-treated high-solid imitation leather superfin...
