For papermaking and other industrial fabrics, it is desirable to have a means for monitoring wear on the fabric, particularly at any point on its inner and outer surfaces, even when the fabric is installed on a machine that is operating. The invention relates to wear level indicating filaments and the fabrics made thereof. Disclosed are filaments with multiple (14, 16, 18) layers surrounding a core (12) 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.
