Abstract

A single layer textile for manufacturing a construction material is obtained by weaving warps and wefts. Each of the warps are selected from a monofilament, a monofilament twine and a core line yarn having a core line of a monofilament, and a bundled yarn having small-diameter raw yarns bundled to form fine water sucking spaces between the raw yarns. The wefts contain both monofilaments and the bundled yarns.

Claims

1. A single layer textile for manufacturing a construction material, comprising warps and first and second wefts;

wherein each of the warps is a monofilament containing warp selected from a group consisting of a monofilament, a monofilament twine and a core line yarn having a core line of a monofilament, or is a bundled yarn in which small-diameter raw yarns are bundled to form fine water sucking spaces between the raw yarns;

each of the first wefts is a monofilament; and

each of the second wefts is the bundled yarn; and

the warps are woven with the first and second wefts.

2. The single layer textile for manufacturing construction material according to claim 1, wherein the first warp that forms a first knuckle on the first weft always forms first knuckles on the first wefts and the first warp that forms a second knuckle on the second warp always forms second knuckles on the second wefts;

each of the first knuckles has a first shape and each of the second knuckles has a second shape, the first and second shapes are different.

3. The single layer textile for manufacturing the construction material according to claim 1, wherein the first and second wefts are alternately disposed;

and a tissue of the warps comprises (i) first warps that pass over the first weft, and next pass under the second weft, the first weft and the second weft, and (ii) second warps that passes over the second weft, and next pass under the first weft, the second weft and the first weft.

4. The single layer textile for manufacturing the construction material according to claim 1, wherein the monofilament, the monofilament twine and the core line yarn is not less than 30% of textile construction yarns.

5. The single layer textile for manufacturing the construction material according to claim 1, wherein the bundled yarn is selected from a group consisting of a span yarn, a multifilament, a raising yarn, a monofilament twine, a mole yarn, a filament process yarn, a yarn in which a span yarn is wound on a core line of a monofilament and a yarn in which at least two kinds of these yarns are co-twined.

6. The single layer textile for manufacturing the construction material according to claim 1, wherein the core line yarn is a yarn in which a span yarn or a multifilament is wound on a core line of a monofilament.
