Abstract

The invention discloses a three-dimensional papermaking felt and a making method thereof. The three-dimensional papermaking felt comprises a surface flocking layer, an upper-layer base cloth layer, a lower-layer base cloth layer and a reverse-side flocking layer, wherein the lower-layer base cloth layer comprises a warp thread sub-layer and a weft thread sub-layer which are vertically stacked, and the warp thread sub-layer and the weft thread sub-layer are fixed through binding lines to form the lower-layer base cloth layer. The three-dimensional papermaking felt is characterized in that the warp thread sub-layer and the weft thread sub-layer are not provided with weaving points and are fixed through the binding lines to form a whole, the third dimensionality is increased spatially, so that the warp thread sub-layer and the weft thread sub-layer form a three-dimensional woven fabric, the structural stability and crushing resistance of the felt in the whole three-dimensional direction are increased, and the three-dimensional papermaking felt has elastic restoration, pressure microcosmic uniformity and uniform dehydration property, does not easily deform, is long in service life, easy to clean and free of felt marks and can meet the demands of various papermaking machines.

Description

technical field [0001] The invention relates to a felt for pressing paper webs on a paper machine, in particular to a three-dimensional paper-making felt and a preparation method thereof. Background technique [0002] As an indispensable dehydrating material in the papermaking industry, papermaking felts can dehydrate, support paper sheets, and smooth and modify the paper surface. Therefore, the structure and performance of the papermaking felt play a key role in the quality of the formed paper. When the paper machine is running, the felt will be repeatedly squeezed in the press area, so the felt is not only required to have excellent dehydration performance, but also has good structural stability, compaction resistance, elastic recovery and long service life. life. [0003] Existing paper-making felts: one is the bottom net felt, which mainly combines the fiber web obtained by carding and laying on both sides of the base net through the needle punching process. Woven fab...
