Method for producing fiber non-woven fabric superfine fiber synthetic leather

The invention relates to a method for producing fiber non-woven fabric superfine fiber synthetic leather, belonging to the technical field of production of synthetic leather. The method comprises the following steps of wet-method impregnating, coating, solidifying, water washing, drying shaping, dry-method veneering and line rubbing to obtain the fiber non-woven fabric superfine fiber synthetic leather, wherein a special fiber adopted by the method is mucilage glue and PA (Polyamide), mucilage glue fiber has soft hand feeling and good elasticity, the softness of the the mucilage glue fiber isnot basically influenced but the fiber strength of the mucilage glue fiber is worse after the mucilage glue fiber is impregnated in a dimethylformamide solution of polyurethane resin slurry. The PA has better physical mechanical performance, and the softness of the PA is not increased excessively after the PA is impregnated in the dimethylformamide solution of the polyurethane resin slurry. The mucilage glue fiber and the PA both are complemented, and a majority of advantages of superfine fiber synthetic leather can be realized through utilizing a reasonable formula and the technique operation above during a dry-wet method; therefore, the fiber non-woven fabric superfine fiber synthetic leather produced by the method disclosed by the invention has the advantages of soft and thick hand feeling, smooth and full grains and attractive appearance and further has better physical mechanical properties such as strong force, tearing strength and peeling strength.
