Problems solved by technology

Although the performance of the third-generation high-wire bottom wire needle-punched papermaking felt has been greatly improved compared with the first-generation and second-generation paper-making felts, there are still defects in the dehydration process of the high-wire bottom wire needle-punched papermaking felt. Problems such as high moisture content of paper sheets in the press area, low dehydration efficiency during the press process, and large consumption of steam for paper sheets entering the drying cylinder, etc.

Embodiment Construction

[0011] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 Shown: the present invention provides a kind of high-efficiency dehydration papermaking felt, mainly comprises fiber skeleton layer 1, paper surface fiber layer 2 and bottom water absorption layer 3; It is characterized in that paper surface fiber layer 2 and bottom water absorption layer 3 are all made of polyacrylic acid super Woven from absorbent fibers. The paper surface fiber layer 2 is woven from thin filaments with a diameter of 0.20-0.25mm and a filament density of 120 fibers / cm; the bottom absorbent layer 3 is woven from thick filaments with a diameter of 0.30-0.40mm. The density was 80 fibers / cm.

[0013] The fibrous skeleton layer 1, the paper fiber layer 2 and the bottom water-absorbing layer 3 are combined by a special acupuncture process, and then shaped by a hot oil roller at high temperature to make them tigh...

Abstract

The invention relates to efficient dehydrating paper making felt. The efficient dehydrating paper making felt comprises a fiber skeleton layer, a paper surface fiber layer and a bottom water accepting layer. The efficient dehydrating paper making felt is characterized in that the paper surface fiber layer and the bottom water accepting layer are woven through polyacrylic acid super absorbent fibers. According to the efficient dehydrating paper making felt, the paper surface fiber layer is woven through filaments to improve the smoothness of the paper surface; the bottom water accepting layer is woven through thick filaments to increase the water accepting effect and improve the drying efficiency; the water saturation of the papermaking felt is improved greatly and the speed of moisture transferring from a damp paper sheet to the felt is improved by a large margin due to the fact that the paper surface fiber layer and the bottom water accepting layer are woven through the polyacrylic acid super absorbent fibers.

Description

technical field [0001] The invention belongs to the field of papermaking felts, in particular to a high-efficiency dehydration papermaking felts. Background technique [0002] Papermaking felt is a professional dewatering equipment in the press section of a paper machine. Its organizational structure, dehydration performance, bearing strength and service life are closely related to the production efficiency, product quality and production cost of the paper machine. There are three generations of paper-making felts in the prior art. The first generation is a woven felt; the second-generation is an all-chemical fiber needle-punched non-woven felt; and the third-generation is a needle-punched paper-making felt with a high-line bottom mesh. Although the performance of the third-generation high-wire bottom wire needle-punched papermaking felt has been greatly improved compared with the first-generation and second-generation paper-making felts, there are still defects in the dehyd...
