Manufacture method of secondary-seaming ternary-papermaking forming net

Abstract

The invention discloses a manufacture method of a secondary-seaming ternary-papermaking forming net. Sixteen heald frames are adopted to interweave polyester or nylon monofilaments into three layers of different weaving structures into a whole, the three layers of different weaving structures comprise a paper-forming layer, an intermediate connecting layer and a machine layer, the minimum tissue unit comprising sixteen polyester monofilaments as warps and thirty-two polyester or nylon monofilaments as wefts, the warp number ratio of the paper-forming layer to the machine layer is 1:1, the weft number ratio of the paper-forming layer to the machine layer is 2:1, and the intermediate connecting layer comprises one half of total wefts and is characterized by being formed by the secondarily seaming of the self warp seaming and the self weft seaming of the paper-forming layer. The invention has the advantages of smooth papermaking surface, firm interlayer binding force, no internal abrasion or net elongation and compact and even net structure, and the machine layer has wear resistance, small thickness, long service life and strong dewatering performance.

Description

technical field [0001] The invention relates to a method for manufacturing a double-stitched three-layer paper forming net, which is a kind of wire net equipment used in the wet part of a paper machine for forming and dehydrating paper sheets. Background technique [0002] Paper forming wire is an important forming and dehydrating material in the wet part of paper machine. Paper forming wire directly affects the quality of paper. At present, the competition in the paper industry is becoming increasingly fierce, and paper machines are developing at high speed and wide width. This requires the development of new products of paper forming wire. Development should keep up with the development of papermaking. At present, the existing two-layer and two-and-a-half-layer forming fabrics can no longer meet the needs of high-speed and wide-width paper machines. There are two types of existing three-layer forming fabrics for papermaking: weft-sewn three-layer fabrics and warp-sewn thre...

Problems solved by technology

[0003] In order to overcome the uneven formation of the existing three-layer forming wire for papermaking, obvious web marks, weak interlayer bonding and internal wear, elongation of the wire, decreased wire tension, short service life, and poor dehydration performance etc., the present invention provides a paper surface that can make the paper surface smooth, the bonding force between the layers is firm, no internal wear, no net elongation, tight and uniform net structure, wear-resistant machine layers, small thickness, long service life, and dehydration. A double-stitched three-layer paper forming fabric manufacturing method with strong performance
