High-grade daily used paper-polyester fibres three-layer wire-cloth

Abstract

The invention provides 24 harness self-binding polyester three-layer wire-cloth, wherein polyester and nylon monofilament is interwoven to be composite intertexture of a structural connection whole body of a paper forming layer, an intermediate connection layer and a machine layer by 24 pieces of harness frames, the minimum organization unit is composed of 24 polyester monofilaments as a warp thread and 36 polyester or nylon monofilament as a weft thread. Number ratio of warp threads of the paper forming layer to that of the machine layer is 1:1, and number ratio of weft threads is 3:2; the number of weft threads is 2 / 6 of total number of the weft threads; the paper forming layer employs plain weave method, and the machine layer employs 6 harness weave method. The invention has advantages of high fibre supporting index, high retention of fibre and fillers, uniform forming of page, easy peeling of page from net, flattening paper forming, firm combination of upper and lower layers, good abrasive resistance and long service life.

Description

Technical field [0001] The invention relates to the wet end of a paper machine, in particular to a wire mesh device used in the wet end of a paper machine for sheet forming and dehydration, that is, high-grade household paper-polyester fiber three-layer paper-making wire. Background technique [0002] Papermaking forming wire is an important forming and dewatering material in the wet end of a paper machine. Although the existing papermaking forming wire can basically complete the task of paper sheet forming and dewatering, its disadvantage is that the surface layer of the existing papermaking forming wire is uneven. , uneven mesh, large gaps, and low fiber support index, resulting in obvious texture on the surface of the paper, resulting in low retention of fibers and fillers in the paper, uneven sheet formation, and difficult peeling of the paper from the net, which is not suitable for The need to produce high-grade paper. Moreover, the binding force between the paper form...

[0002] Papermaking forming wire is an important forming and dewatering material in the wet end of a paper machine. Although the existing papermaking forming wire can basically complete the task of paper sheet forming and dewatering, its disadvantage is that the surface layer of the existing papermaking forming wire is uneven. , uneven mesh, large gaps, and low fiber support index, resulting in obvious texture on the surface of the paper, resulting in low retention of fibers and fillers in the paper, uneven sheet formation, and difficult peeling of the paper from the net, which is not suitable for The need to produce high-grade paper

Moreover, the binding force between the paper forming layer and the machine layer of the existing papermaking forming wire is weak, and separation and relative displacement between layers are easy to occur, and the wear resistance of the contact surface between the machine layer and the paper machine is not enough, resulting in a short service life of the papermaking forming wire
