METHOD FOR MANUFACTURING AN INTERIOR TRIM PART OF AN AUTOMOTIVE VEHICLE COMPRISING A VELVET FONT LAYER AND ASSOCIATED PART

摘要

An interior trim part made by a method that includes the steps of bringing a fiber web onto a conveyor, needlepunching the fiber web to form a base in contact with the conveyor, and introducing a binder component on the base. The binder component introduced on the base is a thermoplastic polymer in solid form. The method includes a step for heating the base to cause the thermoplastic polymer making up the binder component to penetrate the base over a thickness smaller than the thickness of the base.

1. A method for manufacturing an interior trim part of an automotive vehicle, comprising the following steps:
bringing a fiber web onto a conveyor equipped with brushes, the fiber web comprising base fibers, the fiber web comprising a quantity of strictly more than 0 wt % and of less than 15 wt % of binder fibers that are at least partially fusible; needlepunching the fiber web opposite the brushes to form a base in contact with the conveyor and a velvet font layer opposite the conveyor; thermobonding the fiber web; introducing a binder component on the base, the binder component introduced on the base being a thermoplastic polymer in solid form; heating the base after applying the thermoplastic polymer making up the binder component to cause the thermoplastic polymer making up the binder component to penetrate the base over a thickness smaller than the thickness of the base.
