Abstract

The utility model relates to a high-strength blended knitting fabrics, made of the longitude thread of the plastic flat filament and the woof of the plastic continuous yarn interlaced each other. The high-strength blended knitting fabrics of the utility model can reduce the friction between the longitude thread and the woof while in the process of weaving and using. With the same gram weight, the intensity in the longitude and latitude direction of the knitting fabrics is greatly improved. The high-strength blended knitting fabrics can be widely applied to the civil engineering materials of the base building of the improvement of express highways, railways, bridges around the sea, dykes, channels, etc; and the base material of the container bag for containing the bulk loading cargoes.

Description

High strength blending woven cloth

Technical field

The utility model relates to a kind of high strength blending woven cloth of making packaging bag, geotextiles.

Background technology

Openly be used to make woven cloth such as packaging bag, geotextiles in the market and all be interweaved as warp and parallel and form with plastic flat fiber.Because plastic flat fiber has certain rigidity, therefore in weaving, mobile between warp and the parallel caused mutual friction, but this phase mutual friction makes and has produced shearing force between the flat filament that intersects vertically, make the intensity decreases of warp and parallel, especially the intensity of parallel often is lower than the intensity of warp, and therefore the intensity of braiding back base cloth all has decline.Be to improve the intensity of braiding base cloth, normally the intensity by improving flat filament or the density of regulating graticule realize, this not only increases manufacturing cost, but also has increased the weight of braiding base cloth unit are.High-intensity flat filament still exists through, parallel phase mutual friction and produces the problem of mutual shearing in weaving process.In addition, in use, after the braiding base cloth was subjected to gravity, owing to producing relative displacement between warp, the latitude flat filament, the friction between same warp, the parallel also can reduce the intensity that weaves base cloth, and therefore present woven cloth is difficult for satisfying the requirement of hanging down the gram weight and high strength degree.

Summary of the invention

The purpose of this utility model provides a kind of high strength blending woven cloth, weave with use in, can reduce through the friction between, the parallel, under prerequisite, increased substantially braiding base cloth intensity through, broadwise with grammes per square metre.

The technical scheme that the utility model achieves the above object is: a kind of high strength blending woven cloth is that parallel with the warp of plastic flat fiber and plastics long filament is interweaved and forms.

The utility model adopts plastic flat fiber as warp, long filament is as parallel, in weaving process, plastic flat fiber and flexible filament with certain degree of hardness are interweaved, owing to obviously reduced the friction between warp and the parallel, therefore it is minimum flat filament and long filament shearing force each other to be reduced to, and fabric is also soft.Shape because of long filament is plastic simultaneously, no matter weave with use in, can both reduce relatively moving between warp and the parallel, reduce friction between the graticule, compare with the braiding base cloth with grammes per square metre, the intensity of warp has improved about 10%, and the intensity of parallel can be brought up to 1.2～1.4 times through line strength, thereby increased substantially the intensity of braiding base cloth, realized the requirement of the low gram weight and high strength degree of woven cloth, reduced use cost effectively.The utility model need not to change the production technology of plastic woven cloth, easily guarantees product processing quality.The blending woven cloth that the utility model interweaves with plastic flat fiber and flexible filament has good permeable, permeability, and can reach indexs such as effective aperture and vertical infiltration coefficient by warp, the weft density of adjusting base cloth, can satisfy various construction requirements, especially underwater construction effect is especially obvious, can be widely used in highway, railway, enclose the construction timber for earth-work material of capital constructions such as extra large bridging, dykes and dams, waterway regulation and the container bag base material of dress bulk goods.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

The specific embodiment

High strength blending woven cloth of the present utility model, see Fig. 1, shown in 2, be vertical mutually being interwoven of parallel with warp with the plastics long filament 2 of plastic flat fiber 1, its flat filament 1 is that the polypropylene fibre wire drawing is made, and the width of flat filament 1 is between 1.15mm～5.2mm, thickness is between 0.035mm～0.25mm, long filament 2 of the present utility model adopts polypropylene fibre or polyamide fibre or terylene spray silk to make, the line density of long filament 2 is between 750D～4000D, adopt the utility model blending woven cloth, when warp-wise density at 58/10cm, latitudinal density is when 52/10cm, after testing, warp-wise tensile strength is at 2350N/5cm～2400N/5cm, and broadwise tensile strength is at 2550N/5cm～2650N/5cm, under prerequisite, increase substantially braiding base cloth warp with grammes per square metre, the intensity of broadwise.
