Example Embodiment
[0030] (1) Preparation of 37-island polyester fixed-island microfiber nonwoven fabric: firstly, 37-island 5dtex×51mm, 70% PET / 30% COPET bi-component fixed island short staple fiber is needle punched into 400g / m 2 The polyester microfiber non-woven fabric.
[0031] (2) Water-based polyurethane impregnation: polyester super fiber non-woven fabric is impregnated with aliphatic water-based polyurethane with a solid content of 35% and a viscosity of 600 cps, and the polyester super fiber non-woven fabric is impregnated with 220% of liquid and dried in a blower oven.
[0032] (3) Disperse dye dyeing and finishing of non-woven fabric impregnated with polyurethane: weigh the base fabric of step 2) into the dyeing tank, because the fiber fineness is 5dtex, the diameter is small, and the particle size of the disperse dye is selected Below 0.5μm, because the particle size of the dye is small, the dispersibility in the solution is good. In the dye bath at 130°C, the disperse dye is easier to pe...

[0035] 1) Preparation of 37-island polyester fixed-island microfiber non-woven fabric: the fineness of 5dtex, 70% PET / 30% COPET bi-component 37-island fixed-island fiber is processed into a gram weight of 400g / m through a needle punching process 2 Superfine fiber non-woven fabric;
[0036] 2) Water-based polyurethane impregnation: impregnating water-washed polyurethane with a solid content of 35%;
[0037] 3) The non-woven fabric impregnated with polyurethane and dried is dyed with disperse dye: 220% of the liquid is dried and then dyed at 130°C under high temperature and high pressure, and the disperse dye particle size is about 2μm;
[0038] 4) Perform alkali reduction treatment on the base fabric in step 3): After dyeing and washing, perform alkali reduction finishing, with a sodium hydroxide concentration of 3%, reaction at 95°C for 60 minutes, and washing and drying to obtain polyester superfiber suede leather.
