Abstract

Provided is a strong toughness fiber bifunctional latitude polyester triple-layer forming fabric comprising polyester and nylon monofilaments filament yarns interweaved together which is characterized by the 16 filament weaving. The smallest weaving tissue structural unit comprises a composite mixture fabric of three different weaving tissues of a finised paper surface layer, a medium connecting layer and a bottom network layer connected up and down into an integrated body. The three different weaving tissues are weaved by 16 polyester monofilaments filament yarns as longitude and 48 polyester and nylon monofilaments filament yarns as latitude. The ratio of the number of the longitudes in the finised paper layer surface layer and the bottom network layer is 1:1 and the ratio of the number of the latitudes is 3:2. The number of the latitudes in the medium connecting layer is 1/3 to the total number of the latitudes. The utility model as high speed paper machine wet par paper forming and dehydration network product has the advantage that the finised paper has a plane surface, and a high supporting index to the pulp fiber and is easy to be separated from the paper sheet. The medium connecting layer has a firm bonding force and is not easy to move and to be stripping off. The bottom network layer has a good wear resistance and a long working life.

Description

The difunctional parallel polyester of high-toughness fibres three-layer forming net

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 the difunctional parallel polyester of a high-toughness fibres three-layer forming net as the papermaking wire-cloth of paper sheet formation and dehydrating material.

Background technology

Though existing three-layer forming net for paper making can be finished the paper sheet formation in the paper-making process substantially and remove 90% above moisture content task, its weak point is that the one-tenth paper working face of this kind net is uneven, becomes the paper surface crazing obvious; Be clipped in into intermediate connecting layer parallel between paper layer and the spacer screen layer and only account for the 1/9-1/5 of whole parallels, the adhesion weakness of interlayer, layer and interlayer are easy when running up on paper machine

Looks is separated with interlayer slippage; Spacer screen layer and papermaking machine contact-making surface wear no resistance, and be easy to wear, and service life is short.

Summary of the invention

Become paper flatness, spacer screen layer abrasion resistance poor in order to overcome existing paper grade (stock) polyester three-layer forming net, the deficiency of weak easily relative slippage of intermediate connecting layer adhesion and splitting etc., the utility model provides the difunctional parallel polyester of a kind of high-toughness fibres three-layer forming net, make it become paper smooth, the intermediate connecting layer adhesion is strengthened, 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, the difunctional parallel polyester of a kind of high-toughness fibres three-layer forming net, be interwoven by polyester and Tynex, it is characterized in that adopting 16 comprehensive weaving, its minimum weave construction unit is that warp is that parallel is woven into into the paper layer with 48 polyester and nylon monofilament long filament by 16 monofilament polyester long filaments, three layers of different weaving structure of intermediate connecting layer and spacer screen layer connect into whole compound intertexture up and down, the ratio of the one-tenth paper layer of the difunctional parallel polyester of above-mentioned described high-toughness fibres three-layer forming net and the warp of spacer screen layer is 1: 1, and the ratio of parallel is 3: 2; The intermediate connecting layer parallel accounts for 1/3 of total parallel radical; The working face that the spacer screen layer of the difunctional parallel polyester of above-mentioned described high-toughness fibres three-layer forming net contacts with paper machine is combined the satin weaves method braiding that interweaves by the polyester of diameter 0.35-0.45 millimeter and nylon monofilament long filament with 16; The one-tenth paper layer of the difunctional parallel polyester of above-mentioned described high-toughness fibres three-layer forming net is made warp by the monofilament polyester long filament of diameter 0.25-0.27 millimeter, and the monofilament polyester long filament of diameter 0.20-0.22 millimeter interweaves with the plain weave weave as parallel.

It is smooth that the beneficial effects of the utility model are into paper, to the fiber support index height in the paper pulp, becomes paper level and smooth, separates with paper easily, and the intermediate connecting layer firm binding force is difficult for producing interlayer slip and peeling off, and the ABRASION RESISTANCE of spacer screen layer is good, longer service life.

The specific embodiment

In Fig. 1 Fig. 2, the difunctional parallel polyester of a kind of high-toughness fibres three-layer forming net is interwoven by polyester and nylon monofilament long filament, it is characterized in that adopting 16 comprehensive weaving, its minimum weave construction unit is that warp is that parallel is woven into into the paper layer with 48 polyester and nylon monofilament long filament by 16 monofilament polyester long filaments, three layers of different weaving structure of intermediate connecting layer and spacer screen layer connect into whole compound intertexture up and down, the ratio of the warp radical of above-mentioned described one-tenth paper layer and spacer screen layer is 1: 1, the ratio of parallel is 3: 2, and the intermediate connecting layer parallel accounts for 1/3 of total parallel radical; The working face that above-mentioned described spacer screen layer contacts with paper machine is combined the satin weaves method braiding that interweaves by the monofilament polyester long filament of diameter 0.35-0.45 millimeter with 16, and above-mentioned described one-tenth paper layer is interweaved with the plain weave weave as parallel by the polyester or the nylon monofilament long filament of diameter 0.25-0.27 millimeter monofilament polyester long filament as warp and diameter 0.20-0.22 millimeter.
