AI Technical Summary

⚠Technical Problem

Existing automotive trim part constructions using structured needlefelt carpets face issues with delamination, strike-through of glue elements, and unwanted visual appearance due to fiber contamination, while requiring adhesive layers for abrasion performance, which also affect recycling and production waste.

⚗Method used

A carpet construction comprising a fibrous structured needlefelt top layer and a backing layer with thermoplastic binder, where fibers from the top layer extend into the backing layer and are locked by the binder, eliminating the need for separate adhesive layers and maintaining a soft pile appearance.

🎯Benefits of technology

The solution provides a strong, abrasion-resistant carpet construction with improved visual appearance and reduced production waste, allowing precise moulding and easier recycling by eliminating adhesive layers.

Abstract

Automotive trim part comprising a carpet layer consisting of a fibrous structured needlefelt top layer, and a backing layer comprising a fibrous needlefelt layer, whereby the fibrous needlefelt layer comprises fibers and a thermoplastic binder. The fibers from the needlefelt top layer extend into the backing layer and the extended fibers in the backing layer are locked in place by the thermoplastic binder of the backing layer.
