40 μm and the like can be mentioned. The shape of the weave using the flat yarn 3 may be appropriately selected from plain weave, twill weave and the like. The number of warp and weft threads is 4 to 50 / inch in the warp direction and 4 to 50 / inch in the weft direction.
Inches are suitable, especially in the case of plain weave, in order to improve the convergence at the time of winding, the number of units per unit length driven in the direction perpendicular to the winding direction may be slightly reduced,
If necessary, a single-layer flat yarn made of a polyethylene-based resin composition or the multi-layered flat yarn 3 made of a thermoplastic resin other than the polyethylene-based resin composition is used as a warp or a weft of a woven fabric to form a base fabric 5 as needed to enhance strength. Surface layer 6
Although it may be driven to such an extent that it does not impair the adhesiveness with, the non-woven fabric formed by aligning warp yarns and weft yarns without woven the flat yarn 3 may be used as the base fabric 5. The flat yarns 3 do not necessarily need to run orthogonally or side by side, and may be laid vertically and horizontally. When the flat yarn 3 has a structure in which the flat yarns 3 run orthogonally or in parallel, the space between the adjacent warp yarns and the weft yarns may be hardly provided, for example, a gap of about 0.1 to 1.5 mm may be provided. .

い。As one of the methods for fusing the polyethylene resin composition to the base cloth 5, there is a melt extrusion laminating method. Specifically, for example, while extruding the material of the surface layer film 6 melted at 280 ° C. to 320 ° C. from the extruder,
The base cloth 5 is pressure-bonded to one side or both sides by a cooling roll or the like called a mirror roll (mirror roll) having a surface roughness of about s to 1.0 s. At the time of pressure bonding, the melted resin composition penetrates into the voids of the flat yarn 3 forming the base cloth 5 and is integrated as a substantially transparent sheet, and a surface layer film having a smooth surface on one or both sides of the base cloth 5. 6 is formed. In order to further increase the transparency of the coating material according to the present invention, it is desirable to apply the surface layer film 6 on both front and back sides.

に外層の比率がより高い方が望ましい。Further, the fusion of the intersecting portions 4 of the warp yarns and the weft yarns of the base cloth 5 can be performed after weaving the base cloth 5, and the melting point of the outer layer 2 of the multi-layer flat yarn 3 can be set to the surface layer. When the surface layer film 6 is applied by the above-mentioned manufacturing method after being set sufficiently lower than the melting point of the film 6, a means for simultaneously forming the surface layer film 6 and fusing the intersection 4 of the warp yarn and the weft yarn of the woven fabric by the heat. Is also possible. The material of the outer layer 2 of the flat yarn melted by heat penetrates into the gap between the warp and the weft to form the base fabric 5 as a single transparent sheet, and is composed of a polyethylene resin of relatively high density, which causes peel strength. In relation to the surface layer film 6, it also functions as an adhesive and also plays a role of increasing the peel strength between the layers constituting the coating material. Multilayer flat yarn The ratio of the thickness of each layer is outer layer: inner layer:
Outer layer = 1: 8: 1 to 4: 8: 4 is a suitable range,
In order to enhance the above function, it is desirable that the ratio of the outer layer is higher, such as 3: 8: 3 to 4: 8: 4.

The density of the polyethylene resin composition of the surface layer film 6 adhered to the base fabric 5 is preferably higher than 0.927 and lower than 0.951 regardless of the material of the inner layer of the multi-layer flat yarn constituting the Can be said. Among them, the density: 0.
Those of 934 g / cubic centimeter to 0.942 g / cubic centimeter are desirable in that they have high abrasion resistance and stable extrusion processability, and the melt flow rate is 4
-20 g / 10 min is desirable.

て展張作業性が悪くなるなどの問題が生じる。That is, when the surface layer film 6 is formed using a polyethylene resin composition having a density of less than 0.934 g / cubic centimeter, the surface of the covering material tends to be easily scratched due to poor wear resistance and lubricity. Yes, it causes the deterioration of transparency to be accelerated. In addition, during the winding and lowering work, the workability tends to be deteriorated due to poor lubricity of the surface of the covering material. On the other hand, the density of the resin composition is 0.94
If it exceeds 2 g / cubic centimeter, problems such as deterioration of workability such as increase of extrusion load and deterioration of workability of spreading due to increased rigidity of the sheet occur.

However, in that case, they may be kneaded in advance with the resin composition or may be dry blended immediately before processing.

Is mentioned. Further, the surface layer film 6 adhered to the front and back of the base cloth 5
May have different thicknesses, but if the thickness is less than 15 μm, not only pinholes are easily generated, but also the heat sealability is deteriorated. On the other hand, when it exceeds 60 μm, the rigidity of the sheet becomes excessively strong, which causes a deterioration in workability.

いる際にも高い実用効果を奏するものである。As described above, the coating material according to the present invention is
Because of the excellent scratch resistance of the sheet surface, the support material that supports the covering material from the side, for example, the aggregate of the house that can prevent slack, and the scratches are less likely to be scratched by rubbing against the pressing obi, etc. The durability period of the sex is dramatically improved,
Combined with the high peel strength, the durability of the side curtain material can be dramatically improved. In addition, since the surface has good slipperiness and there is no stickiness, workability in sheet spreading work, winding, and lowering work is also improved, including use in agricultural facilities such as facility gardening houses and pipe houses, etc. It is also highly practical when used in construction sites and other material storage areas.
