The utility model discloses the wide application is as shaping and dehydration material in paper machine wet end. Its advantages are smooth surface, no net mark, firm binding force of intermediate layer, no slide and stripping between layers, wear-resisting bottom net layer and long service life.

Description

Tough polyester fiber 20 is combined thick order papermaking wire-cloth

Affiliated technical field

The utility model relates to a kind of gauze goods, and specifically a kind of paper machine wet end that is applied in is as being shaped and the papermaking wire-cloth of dehydrating material is tough polyester fiber 20 comprehensive thick order papermaking wire-cloths.

Paper making forming net is important shaping of paper machine wet end and dehydrating material, paper pulp makes on forming net that paper fiber and the crisscross even dispersion of filler form quantitatively, thickness, all spend the page of uniformity, when removing wherein 90% above moisture content page is sent to the press section of paper machine from the paper machine head box.Though existing papermaking wire-cloth is finished paper sheet formation substantially and is removed the task of moisture content, but its weak point is existing papermaking wire-cloth becomes the paper surface crazing obvious, the incompatible needs of producing high-grade culture with paper, become paper layer and spacer screen layer by layer between the adhesion weakness, easily producing slippage separates with interlayer, spacer screen layer and paper machine contact-making surface are not wear-resisting, cause papermaking wire-cloth shorter service life.

Summary of the invention

Become the paper reticulate pattern obvious in order to overcome existing papermaking wire-cloth, interlayer is easily separated, the spacer screen layer is not wear-resisting, the deficiency that service life is short etc., the utility model provides a kind of tough polyester fiber 20 to combine thick order papermaking wire-cloth, makes it become paper more smooth, and the intermediate connecting layer adhesion is stronger, the spacer screen layer is more wear-resisting, long service life.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of tough polyester fiber 20 is combined thick order papermaking wire-cloth, be interwoven by tough polyester and nylon monofilament long filament, it is characterized in that adopting 20 to combine weaving structures, its minimum weaving structure organization unit is a warp with 60 polyester and Tynex monofilament by 20 tough polyester filament monofilament is that parallel is woven into the compound intertexture that three layers of different weaving structure of spacer screen layer that positive one-tenth paper layer, intermediate connecting layer and reverse side contact with the paper machine running gear connect into an integral body up and down.The ratio of above-mentioned described one-tenth paper layer and spacer screen layer warp radical is 1: 1; The ratio of above-mentioned described one-tenth paper layer and spacer screen layer parallel radical is 3: 2; Above-mentioned described intermediate connecting layer parallel radical accounts for total parallel radical and brings up to 1/3 by former 1/9-1/5, to strengthen the adhesion of intermediate connecting layer; Above-mentioned described one-tenth paper layer is that warp and parallel interweave with plain weave structure with diameter 0.11-0.20 millimeter monofilament polyester long filament, meanwhile the one thick one thin alternate intermediate connecting layer that inweaves simultaneously reduces thin staple fibre and filler in the paper pulp and pricks a pair of thinner nylon monofilament long filament that runs off from net and be connected a parallel the parallel with page is played a supportive role as filling and leading up the page reticulate pattern in face picks, another root connects parallel and alternately inweaves, it is more smooth to make into paper, no wire mark; Above-mentioned described spacer screen layer is to be warp and alternately to be that parallel adopts 5 to combine the satin weave structures and interweave with diameter 0.20-0.50 millimeter nylon and monofilament polyester long filament with diameter 0.18-0.27 millimeter monofilament polyester long filament.

The beneficial effects of the utility model are into the more smooth no reticulate pattern of paper layer, make things convenient for page to separate from becoming the paper layer, and paper pulp fiber picking-up rate height has avoided thin staple fibre and the filler in the paper pulp to run off from mesh; Intermediate connecting layer connects parallel and accounts for and make into after total parallel radical rises to 1/3 that adhesion is strengthened between paper layer and the spacer screen layer, even paper machine runs up, papermaking wire-cloth is difficult for producing interlayer slip and peeling off, and is more durable; The spacer screen layer adopts tough wear-resisting thick polyester and nylon monofilament long filament alternately to interweave with 5 comprehensive satin weave structures as parallel, has improved the ABRASION RESISTANCE of spacer screen, longer service life.
