Papermaking squeezing felt

Abstract

The invention provides a papermaking squeezing felt which comprises a fiber net layer, a framework layer and an elastomer layer, the fiber net layer comprises a surface layer fiber net, a middle layerfiber net and a bottom layer fiber net; the framework layer is arranged between the middle layer fiber net and the bottom layer fiber net; wherein the framework layer comprises at least one layer ofupper-layer base net and at least one layer of lower-layer base net; the upper-layer base net and the lower-layer base net are both of a warp and weft interwoven base net structure; the elastomer layer is arranged between the upper-layer base net and the lower-layer base net; the elastomer layer is of an integrally-formed grid type structure. Wherein the fiber net layer, the framework layer and the elastomer layer are connected in an entangled manner in a needling manner; due to the fact that the elastomer layer has good elasticity, after the papermaking squeezing felt is discharged out of a squeezing area, the papermaking squeezing felt is made to expand rapidly due to the good elasticity, negative pressure is formed on the surface of the papermaking squeezing felt, the dryness of paper can be kept, rewetting of paper sheets is reduced, the drying cost of a paper machine is reduced, the energy-saving and consumption-reducing effects are achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of papermaking felts, in particular to a papermaking press felt. Background technique [0002] Paper-making felts are special industrial textiles, and are indispensable valuable consumables in the paper-making industry. Its quality is directly related to the quality of paper produced, the production efficiency of paper machines, and energy consumption. The development of industrial production technology requires that the papermaking felt should have the characteristics of high strength, good flatness, good compression resilience and good dimensional stability. [0003] At present, papermaking felt is a key item used in the steps of wet paper pressing, dehydration or conveying in papermaking technology. Its industrial preparation method is usually to first use synthetic fibers to make a base network with wide gaps and many gaps, and then compound it with non-woven fabrics. , formed by acupuncture, chemical t...
