INDICATION OF THE WEAR LEVEL OF A FABRIC BY THE USE OF FILAMENTS

摘要

The invention relates to wear level indicating filaments and the fabrics made thereof. Disclosed are filaments with multiple layers surrounding a core yarn, where the core and layers are distinguishable from one another so as to indicate fabric wear. Also disclosed are conductive monofilaments used to detect fabric wear, multilayer filaments used to create a guideline on a fabric, and a conductive monofilament that also has a contrasting color used to form a fabric guideline.
