PRODUCTION METHOD OF SYNTHETIC AND COATED LEATHER IN GENERAL, USING MICRONIZED RESINS AND MICRONIZED POLYURETHANE RESIN

摘要

A production method of synthetic and coated leather in general is disclosed, characterised in that it uses a micronized resin powder preferably with dimensions lower than 120 micron. Moreover, a micronized polyurethane elastomeric polymer powder with dimensions lower than 120 micron is disclosed. Advantageously, the said powder can be used to produce an eventually discontinuous sintered film, in particular for production of imitation leather material.
