2. Description of the Related Art Conventionally, as a mesh sheet, a vinyl chloride resin is applied to a base material formed by weaving a synthetic resin yarn such as polyethylene terephthalate into a net shape to impart flame resistance and simultaneously misalignment. Those that have been subjected to prevention processing are generally used. However, in the vinyl chloride resin coating process,
In this method, the substrate is immersed in the emulsion to remove excess adhesion and then dried by heating. This is problematic in that the process is complicated and the working environment is poor.

[0003] Therefore, the yarn to be knitted and woven is a composite yarn composed of two components having a difference in melting point, and a mesh sheet (for example, a real sheet) in which the intersections of the yarns are thermally fused by heat treatment to prevent misalignment. Japanese Patent Application Laid-Open No. 1-78190, Japanese Patent Application Laid-Open No. 4-281040) have been proposed.

[0004]

However, the mesh sheet which is heat-sealed to the base fabric on which the composite yarn is knitted and woven has a lack of flexibility, folds are difficult to be restored, and the appearance at the time of stretching is poor. There is a problem, and an object of the present invention is to provide a breathable mesh sheet that is relatively lightweight, flexible, flexible, and easy to handle.

SUMMARY OF THE INVENTION The present invention provides an air-permeable knitted fabric using a composite yarn 2 having a high-melting polymer 5 as a core and a low-melting polymer 6 on its surface as a warp yarn. A mesh sheet characterized in that a strip 4 having a width of about 5 to 50 mm is formed by replacing a plurality of adjacent composite yarns in at least one direction with a predetermined number of high melting point component yarns 3 in the mesh base material. is there.

As the high melting point polymer 5 of the composite yarn 2 constituting the mesh base material of the present invention, a polyolefin synthetic resin such as polypropylene or high density polyethylene, a polyamide synthetic resin such as nylon, or polyethylene terephthalate The low-melting point polymer is formed of a synthetic resin having a melting point lower than that of the high-melting point polymer by 10 ° C. or more, preferably 20 ° C. or more, such as ethylene-vinyl acetate. Copolymer, ethylene-acrylic acid copolymer, low density polyethylene, linear low density polyethylene, and the like. FIG. 2A shows an example of a composite monofilament, FIG. 2B shows a double monofilament composite monofilament, and FIG.
(c) shows the composite flat yarn in a partial perspective view.

The high melting point component yarn 3 which partially replaces the composite yarn 2 constituting the mesh base is made of a synthetic resin having a relatively high melting point. And the same type or different types may be used. The shape of the yarn is not limited to a flat yarn, a monofilament, a multifilament or the like, but a multifilament which is a converging body of a low fineness filament is most preferably used.

[0008]

According to the mesh sheet 1 of the present invention, a predetermined number of partially adjacent mesh bases composed of composite yarns 2 are replaced with high melting point component yarns 3 to form a belt having a width of about 5 to 50 mm. By forming the body 4 and locating the band 4 at a fold point when packing the mesh sheet 1 or the like, the high melting point component yarn 3 does not fuse with the low melting point polymer 6 of the composite yarn 2, In particular, if the multifilament is a low fineness filament converging body, the mesh sheet 1 is easy to handle with flexibility and resilience.

Therefore, the band 4 formed of the high melting point component yarn 3 is formed at several positions substantially equally divided in the width and length directions of the mesh sheet 1, or at several positions based on the folding method. Is preferred.

[Embodiment] Hereinafter, an embodiment will be described.

As the composite yarn 2, the high melting point polymer 5 is made of high density polyethylene (MI = 1.0, melting point 130 ° C., softening point 126 ° C.)
The low-melting polymer-6 is a low-density polyethylene (MI = 2.4,
A composite monofilament having a core-sheath structure with a fineness of 380dr with a melting point of 109 ° C and a softening point of 87 ° C) and a multifilament with a total fineness of 300dr / 48f made of polyethylene terephthalate as the high melting point component yarn 3 are woven. At a density of 26 × 26 yarns / inch, when weaving with a Sulzer loom, 358 composite monofilaments and then 36 multifilaments are successively and alternately arranged as warps, and the same applies to the weft yarns. The mesh base material is formed by driving as much as possible so that the cross section of the composite yarns is fused by passing through a hot-air drying process. The eyelets 7 were placed at intervals of 350 mm, and the mesh sheet 1 of this example was obtained. FIG. 1 shows the mesh sheet 1 in a plan view.

The mesh sheet 1 of the present embodiment has a multifilament strip 4 having a width of 35 mm arranged every 350 mm in both the longitudinal and vertical directions.

[0013]

As described above, according to the present invention, the high melting point polymer
A mesh base material obtained by heat-sealing a base fabric obtained by knitting and woven a composite yarn having a low melting point polymer on the surface of the composite yarn having a predetermined width by driving a high melting point component yarn in place of an appropriate number of adjacent composite yarns. Since it possesses several bands formed by the high melting point component, the non-fused part of the band has sufficient flexibility and rich flexibility, it is difficult to be creased and the appearance at the time of stretching is good, The air-permeable mesh sheet was easy to handle.
