A kind of papermaking felt and its preparation method

Abstract

The invention discloses a paper making felt. The paper making felt comprises a base cloth and fiber webs arranged at the two sides of the base cloth, wherein the base cloth comprises wefts and a plurality of joint elements; each joint element comprises two layers of warps and a joint ring; the two layers of warps are respectively woven on the wefts; at least part of the warps on one of the two layers pass through the joint ring to form the other layer of warps with the warps on the other layer; the joint rings of the plurality of joint elements are arranged along the direction of the wefts in sequence to form a common hole; a center thread used for jointing is inserted into the common hole. The invention also discloses a preparation method of the paper making felt. The paper making felt has the beneficial effects that base cloth weaving on shuttle / projectile looms can be achieved and the base cloth is shaped like a ring through connection of the joint rings, thus reducing the process difficulty; being independent from the warps and the wefts, the joint rings do not easily have quality problems; further, the formed paper making felt with the joint rings is simple to operate when being loaded and dismounted on paper machines, thus greatly reducing the workload, improving the work efficiency and reducing the manpower resources and the time cost.

Description

technical field [0001] The invention relates to the field of papermaking industry, in particular to a papermaking felt and a preparation method thereof. Background technique [0002] Papermaking felt is an indispensable dewatering equipment in the wet end and press section of modern papermaking. The papermaking felt is loaded on the press roll of the paper machine to carry and transfer the paper sheet. The papermaking felt removes the moisture of the wet paper sheet under the extrusion of the press roll or vacuum suction, and can modify the surface of the paper sheet to a certain extent. [0003] According to whether the papermaking felt has an end structure, it is divided into an endless loop felt and a seamed felt. There are two types of endless endless felts: one kind of base fabric is made into a ring by splicing on a sheet loom, and the other kind of base cloth is woven into a ring by endless weaving; when the endless endless felt is loaded and unloaded on a paper mach...
