Abstract

The invention discloses a multi-layer composite high-line-pressure-resistant papermaking felt and a preparation method thereof. The multi-layer composite high-line-pressure-resistant papermaking feltcomprises a bottom fiber layer, a base cloth layer, an inner fiber layer and a surface fiber layer making contact with paper, wherein all of the layers are arranged in a stacked mode, and the base cloth layer comprises at least two layers of single-layer base cloth. The multi-layer composite papermaking felt is actually formed by compounding a plurality of pieces of single-layer base cloth with awarp and weft weave system, and warp yarns in an upper-layer weave are not easy to embed into gaps of warp yarns in lower-layer weave; after receiving high line pressure, the multi-layer composite papermaking felt is good in resilience, high in water containing space and not easy to deform, and does not lose water filtering performance; and the multi-layer composite papermaking felt facilitates quick transferring of moisture in paper sheets to the papermaking felt, meets the dehydration requirement of a high-speed high-line-pressure paper machine on the papermaking felt, and is prolonged in service life.

Description

technical field [0001] The application belongs to the technical field of papermaking industry, and in particular relates to a multilayer composite high-line-pressure-resistant papermaking felt and a preparation method thereof. Background technique [0002] Papermaking felt is an essential consumable in the press section of a paper machine. Its function is to provide elastic and permeable support to maximize the dehydration of the paper sheet, to modify the surface effect of the paper sheet, and to convey the wet sheet through the press. area and press section. [0003] With the continuous development of the papermaking industry, the papermaking process and equipment are developing in the direction of wide width, high speed, new paper machine structure and better paper performance. The wide-nip pressing form is widely used. The linear pressure of this pressing form is generally above 800KN / m. Therefore, higher requirements are put forward for papermaking felts. In addition t...
