process for the production tiefziehbarer, bound nadelvliese for motor vehicle interiors with reduced tendency to shrink

摘要

this invention concerns a process for the production tiefziehbarer, bound nadelvliese for motor vehicle interiors with tiefgezogenem condition decreased tendency to shrink in the heat, in which the genadelte fleece with a two-stage emulsionscopolymerisation vo a olefinisch unsaturated monomers produced copolymerisate dispersion treatmentin the latexteilchen two phases exist, their glastemperaturen at least 40 degrees c differ, and the treated fleece drying at elevated temperature.
