Problems solved by technology

In addition to the suboptimal use of this method of coating, the high cost of the coating method relative to the base material typically used to manufacture monofilaments for paper machine fabrics and related applications also makes the cost of materials relatively high relative to product performance and effectiveness

Embodiment Construction

[0043] In a first embodiment of the present invention, a full-width base fabric structure or base fabric layer manufactured by conventional techniques such as weaving, knitting, helically wound yarn arrays, or polymer perforated films, using conventional needling equipment, Needling is performed with a portion of the total hair composition. The term part means that the initial layer or layers of batt are applied to the base fabric. As used herein, the base structure or base layer composition includes woven and nonwoven materials such as knitted fabrics, extruded mesh fabrics, spiral link fabrics, arrays of MD yarns or arrays of CD yarns, and spiral wound strips of woven and nonwoven materials bring. Such substrates may comprise monofilament yarns, plied monofilament yarns, multifilament yarns, or plied multifilament yarns, and may be single layer, multilayer, or laminated. Yarn is typically extruded from any of the synthetic polymer resins used by those skilled in the art fo...

Abstract

The present invention relates to paper machine fabrics which are imparted stain resistance and maintain good permeability due to a durable coating which lasts the entire life of the fabric. Fluoropolymers make the fabric stain resistant for the entire life of the fabric.

Description

technical field [0001] This invention relates to the paper industry. Specifically, the present invention relates to a press fabric for a press section of a paper machine having stain resistance. Background technique [0002] During papermaking, a web of cellulose fibers is formed in the forming section of a paper machine by depositing a fiber slurry, which is an aqueous dispersion of cellulose fibers, onto a moving forming fabric. Most of the water in the slurry is drained through the forming fabric, while the cellulosic web remains on the surface of the forming fabric. [0003] From the forming section, the newly formed cellulose web enters the press section, which consists of a series of press nips. A web of cellulosic fibers is supported by a press fabric, or typically between two such press fabrics, and passed through the press nip. In the press nip, the cellulosic web is subjected to compressive forces that force water out of the web and cause the cellulosic fibers i...
