Abstract
The invention discloses the preparation method of a kind of colourless migration playshoes suede Synthetic Leather, use colourless migration, the super fine base fabric of two-sided fluffing of solvent resistant corrosion, and wet method is impregnated with polyether-type hydrolysis resistant polyurethane resin impregnated material against hair, and use and roller is forced containing soaking technology, increase slurry impregnation amount, it is based respectively on aqueous polyurethane/polyacrylic resin material cutter against cant to positive and negative by fabricbase and is coated with technique envelope hair process, the vertical six roller decorticating mills semi-finished product two-sided mill skin wharf's pavement quality to Feng Maohou, change colour through post processing, form colourless migration playshoes suede Synthetic Leather base material.The colourless migration playshoes suede Synthetic Leather of this method manufacture has surface particles sense and velvet is strong, feel, pliability, otch, two-sided color effects etc. are close with corium suede, and are substantially better than suede in colourless migration, the feature of environmental protection, cost performance with aspects such as transitivities.
Description
Technical field
The present invention relates to footwear synthetic leather preparation method field, a kind of colourless migration poly-ammonia of playshoes suede
The preparation method of Lipase absobed leather.
Background technology
Suede is to be polished into velvet-like by corium skin base surface, dyes the first layer lether of various popular color the most again,
There is texture good, the advantages such as outward appearance is elegant and graceful；Traditional Synthetic Leather imitate suede often by wet bottom base or
Flocking on person's fabricbase, plant the mode such as corium powder or sheep bar foaming, then carry out grinding process process, thus reach suede or
The effect of person's corium.The most all there is the shifting of easy colour migration, easy dirty bad maintenance, easily fade, fall floss or the feature of environmental protection is poor in above method
Etc. problem, and do not reach satisfied effect.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of colourless migration playshoes suede Synthetic Leather, with
