(2) preparation of dry method surface layer slurry: by 100 parts of PU resin of dry method, 80 parts of solvents, color chips 4-20 part, mix and obtain dry method surface layer slurry; Described solvent is one of following: solvent is DMF, methyl acetate, ethyl acetate, butyl acetate, MEK;
(3) preparation of artificial leather surface layer: arrived dry method surface layer slurry is conformed on bass prepared by step (1) to rolling after drying;
(4) compound base fabric: the bottom surface of the artificial leather that step (3) is obtained (bass base cloth face) and specific composite for base fabric.
As preferred technical scheme, in step (4), the bottom surface (bass base cloth face) of artificial leather adopts the mode composite for base fabrics such as glue, flame with specific composite for base fabric.
As preferred technical scheme, the described base cloth of step (4) is one of following: 0.3mm～1.0mm woven fabric, 50 grams～220 grams nonwoven fabric, 0.2～0.6 gram of knitted cloth, polar fleece, OXFORD.
As preferred technical scheme, after described step (3), adopt printing: select 200～30 object wheels to carry out 1～5 edition printing treatment income earner fabricate-leather surface layer, described printing treatment agent: to select antifouling treatment agent, various wax sense finishing agent or other common or special finishing agent to carry out surface treatment.
As preferred technical scheme, after printing treatment, adopt embossing: select as required different knurling rolls embossings, to obtain different grain effects.
As preferred technical scheme, after compound base fabric, adopt punching: select as required different patterned roll punchings, to obtain different effect of decorative patterns.
As preferred technical scheme, after adopting punching, rub line and process: according to feel or texture, need to rub line processing to composite lether.
As preferred technical scheme, also comprise WATER REPELLENT TREATMENT: composite water-proof film or other function film more as required.
Explanation of nouns: bass is English word: the transliteration of base, base is exactly the meaning of artificial leather basic unit.
Beneficial effect of the present invention is mainly reflected in: the method can select the artificial leather of different efficacies and texture carry out the post processings such as compound from different base materials (cloth) according to client's different demands, thereby that acquisition has is higher, the artificial leather of physical property, function and texture more specifically.Cost can be effectively controlled.The present invention can select common substrate (cloth) material to produce, can effectively guarantee material supply in time and stability, both guaranteed with low costly, can meet well again client and ask high, look for novelty, ask strange requirement.
