Embodiment Construction

[0022] Hereinafter, preferred embodiments of the present invention will be described by describing fibers and papermaking fabrics woven from them. However, it should be noted that the present invention can be applied to fabrics used in other industrial facilities where wear detection and indication are important. .

[0023] Fabric structures include woven fabrics, spiral wound fabrics, knitted fabrics, extruded mesh fabrics, spiral wound fabrics and other non-woven fabrics. These fabrics may also include monofilament yarns, twisted monofilament yarns, multifilament yarns, or twisted multifilament yarns, and may be single-layer woven, multi-layer woven, or laminated. When the fabric is a spiral wound fabric, the silk may be a spiral wound, and the spiral wound or an insert (filler) that may appear in the inner space of the spiral wound is connected with yarn. Yarns are usually extruded from any of the synthetic polymeric resins used for this purpose by those skilled in the art o...

Abstract

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.

Description

Technical field [0001] The present invention relates to a device for detecting the degree of wear of papermaking fabrics and other industrial fabrics and forming an indication thereon. Specifically, the present invention relates to a multilayer wire and conductive wire used as such a device. Background technique [0002] In the papermaking process, in the forming section of the paper machine, the fibrous pulp is deposited on the moving forming fabric to form a cellulose fiber web. The fibrous pulp is an aqueous dispersion of cellulose fibers. A large amount of water in the slurry is discharged through the forming fabric, while the cellulose fiber web remains on the surface of the forming fabric. [0003] The newly formed cellulose fiber web enters the press section from the forming section, which includes a series of press nips. The cellulosic fibrous web is supported by the press fabric, or is usually located between two layers of such press fabric, passing through the press nip....
