Abstract

The utility model discloses a double-layer paper-making mesh, comprising a surface layer and a bottom layer, wherein the wefts (1) and (2) on the surface layer are polyester monofilaments with different diameters and arranged at intervals; the wefts (3) and (4) on the bottom layer are respectively polyester monofilaments and nylon monofilaments, which are arranged at intervals, and the diameter of the weft (4) is bigger than that of the weft (3); the diameters of the wefts (1) and (2) are smaller than that of the wefts (3) and (4); and a construction unit composed of at least 16 warps and 48 wefts is formed by taking the polyester monofilaments as the warps (5) combination-bound with the surface wefts (1) and (2) and the bottom wefts (3) and (4). The double-layer paper-making mesh has fine and smooth surface and wearproof bottom, not only improves the retention rate of pulp fibers, but also prolongs the service life of the products.

Description

A kind of double layer wire

One, technical field

The utility model relates to a kind of papermaking forming web, a kind of specifically double layer wire.

Two, background technology

Papermaking forming web (abbreviation papermaking wire-cloth) is an a kind of paper making wet part dehydration equipment, by radially forming according to certain preparation method braiding with the monofilament of broadwise.Papermaking wire-cloth is wanted most moisture in the energy filter paper pulp, has good filtration, also wants the support wet page, and the l Water Paper page or leaf is passed to next procedure.This just requires papermaking wire-cloth to have even curface to remove to support page and should have stable structure to transmit page.Yet for the filter effect that obtains, select for use little line footpath monofilament often can't satisfy transfer function, be restricted service life; The situation of filtration and supporting role can appear satisfying again if adopt big line footpath material for the requirement of satisfying service life.Along with the development of high speed paper machine, the single-layer polyester forming web can't satisfy water filtering function, supporting role and transfer function simultaneously.

Three, summary of the invention

The utility model is intended to for high speed paper machine provides a kind of double layer wire, and technical problem to be solved is that one is to increase the service life by architecture advances collection drainage, support and transfer function.

Design of the present utility model is a kind of papermaking wire-cloth that comprises surface layer and fabric of design, and surface layer contacts with page and mainly plays a part to support page, and bottom has contacted the effect of setting off with machine, is wear surface.Adopt the filling-backed weave of warp associating access node surface layer and bottom.Concrete technical scheme be parallel 1 and 2 on the surface layer (calling the face picks line in the following text) be two kinds of different-diameters monofilament polyester alternately, the ratio of two kinds of face picks lines is 1: 1; Parallel 3 and 4 on the bottom (calling the back weft line in the following text) for monofilament polyester and nylon monofilament alternately, the diameter of nylon back weft line is greater than the diameter of polyester back weft line, the ratio of two kinds of back weft lines is 1: 1; Face picks line 1 and 2 diameter are all less than the diameter of

back weft line

3 and 4; The ratio of face picks line and back weft line is 2: 1, as shown in Figure 1; With the monofilament polyester is that the minimal structure unit that four kinds of parallels of warp 5 associating access nodes constitute comprises at least 16 warps and 48 parallels, and the circulation of construction unit constitutes double layer wire.

Design feature of the present utility model also is: the diameter of parallel 1 is less than the diameter of parallel 2, as shown in drawings.

This double layer wire is selected the structure of fine line diameter and big density at surface layer, by different reinforcement satin weave method increase surface layer parallel 1 and warp 5 the intertwined point, make and under the prerequisite that guarantees certain dewatering, increase the retention of paper pulp, reduce stock losses, and adopting big line footpath and little density structure to strengthen wear-resisting and dewatering at bottom, braid method is the heavy satin weave of filling face.

This double-deck papermaking wire-cloth, the top layer exquisiteness, smooth.The filling face of bottom large span is organized wear-resisting.In improving paper pulp, in the retention of fiber fines, increased the service life of product.Stability Analysis of Structures improves into paper efficient.

Four, description of drawings

Fig. 1 is the utility model cross-sectional view.Circular cross-section is the parallel section among the figure, and what diameter was less is face picks line 1 and 2, directly through bigger be back

weft line

3 and 4.

Five, the specific embodiment

In conjunction with the accompanying drawings, non-limiting examples is described below:

Get Ф 0.15mm, Ф 0.20mm monofilament polyester is done face picks line 1 and 2 respectively; Get Ф 0.45mm monofilament polyester and make back weft line 3; Get Ф 0.47mm nylon monofilament and make back weft line 4; Get Ф 0.20mm monofilament polyester and make warp 5 (black lines); The heavy satin weave of the filling face method weaving that interweaves is adopted in the bottom surface, warp 5 associating access node face picks line 1,2 and

back weft lines

3,4, face picks line 1,2 ratios 1: 1, alternately,

back weft

3,4 ratios 1: 1, alternately, face picks line and back weft line ratio 2: 1,42/cm of warp density, 45/cm of weft density, constitute the minimal structure unit by 16 warps and 48 parallels, the circulation of minimal structure unit constitutes double layer wire.By increasing the intertwined point of parallel 1 and warp 5, reaching increases the surface layer flatness, reduces stock losses, improves into the purpose of paper efficient.

Claims

1. a double layer wire comprises surface layer and bottom, it is characterized in that: parallel on the surface layer (1) and (2) are the monofilament polyester of two kinds of different-diameters and alternately, the ratio of face picks line (1) and (2) 1: 1; Parallel on the bottom (3) and (4) are respectively monofilament polyester and nylon monofilament and alternately, nylon back weft (4) diameter is greater than polyester back weft (3) diameter, the ratio of back weft line (3) and (4) 1: 1; The diameter of face picks line (1) and (2) all less than with the diameter of back weft line (3) and (4), face picks line (1) and (2) are 2: 1 with the ratio of back weft line (3) or (4); With the monofilament polyester is that warp (5) associating access node face picks line (1) and (2) and back weft line (3) and (4) constitute at least by 16 warps and 48 construction units that parallel is formed.

2. double layer wire according to claim 1 is characterized in that: the diameter of parallel (1) is less than the diameter of parallel (2).
