Verfahren zur Herstellung von lederaehnlichen Vliesstoffen

摘要

Leather-like sheet materials having good moisture permeability and having appearance, texture, touch, drape and grain break similar to those of leather are produced by applying a layer of a solution of a polymer capable of being coagulated in a wet process onto a support; immersing the polymer solution applied to the support into a coagulation bath to coagulate the polymer solution layer into a porous structure; bonding a substratum to the surface of the resulting porous film which has not been in contact with the support and removing the support from the film.
