Abstract

The invention discloses a composite papermaking felt and a preparation method thereof, the composite papermaking felt comprises a first composite fiber layer and a second composite fiber layer, and the second composite fiber layer is laid on the first composite fiber layer; wherein the second composite fiber layer is provided with a plurality of wool layers, needling traces are formed on the wool layers, and the depths of the needling traces are gradually reduced along with the increase of the number of the wool layers. Through a special flocking needling method, the manufactured composite papermaking felt is not prone to hair falling, the smooth and fine effect of the felt is guaranteed, and the composite papermaking felt is particularly suitable for papermaking of paper products such as decorative paper, cultural paper and tissue paper with the high flatness requirement.

Description

technical field [0001] The present application relates to the technical field of the papermaking industry, in particular to a composite papermaking felt and a preparation method thereof. Background technique [0002] Papermaking felt is one of the necessary materials in the papermaking industry. It is a dewatering device in the press section of a paper machine. Its main function is to dewater the nip in the press section, support the wet paper sheet, and guide the wet paper web through the nip. [0003] At present, the papermaking felt commonly used on paper machines is the bottom mesh needle-punched flocking felt, which is generally composed of a base fabric layer and a fiber layer. big performance difference. In addition, different pressing forms of paper machines and different types of papermaking have different performance requirements for papermaking felts. For example, papermaking felts made of board paper have relatively low requirements for surface flatness, while ...
