Problems solved by technology

[0003] Conventionally, a method of laying a plastic sheet, a rubber-coated fabric sheet, etc. on the soil has been used as a weed-proof sheet, but the plastic sheet, rubber-coated fabric sheet is not water-permeable, and rainwater, etc. Water does not penetrate into the ground, so if it is laid between trees, there is a problem that the soil will dry out and the trees will die

Embodiment 1

[0095] Multifilament yarn with a total fineness of 84dtex / 36f using black spun-dyed yarn made of PET as a single yarn (Z-direction twisting, number of twists: 400T / m, heat setting conditions: 85°C x 40 minutes) As the first warp yarn, a multifilament yarn with a total fineness of 84 dtex / 36f (S twisted, number of twists: 400 T / m, heat setting condition: 85° C. ×40 minutes) as the second warp. The twist coefficients of the first warp yarn and the second warp yarn are both 1.2. A multifilament yarn (heat setting condition: 130° C.×40 minutes) with a total fineness of 167 dtex / 36f, in which a single yarn was made of a PET black process-dyed yarn, was used as a weft yarn. These first warp yarns, second warp yarns, and weft yarns were combined so that the warp yarn density obtained by combining the first warp yarn and the second warp yarn was 309 yarns / 2.54 cm, and the weft yarn density was 100 yarns / 2.54 cm. The grass-proof sheet of Example 1 was obtained by weaving double-layer...

Embodiment 2

[0098] Set the twisting of the first warp yarn to S-direction twisting, set the twisting of the second warp yarn to Z-direction twisting, and set the weaving structure to double 7 pieces of warp with the direction of the twill weave pattern of the base structure on the surface side to the upper left The weed control sheet of Example 2 was obtained by weaving similarly to Example 1 except the satin weave.

[0099] The twill grain angle α of the grass-proof sheet of embodiment 2 is on average -41 °, and the twist angle β is on average -17 °, and the angle difference between the twill grain angle α and the twist angle β is 17~32 °, and the difference rate is 58.5 ( %), satisfying the aforementioned formula (2). The cover factor (CF) was 4124.

Embodiment 3

[0101] Weaving in the same manner as in Example 1 except that the warp density obtained by combining the first warp yarn and the second warp yarn is 283 / 2.54 cm and the weft density is 106 / 2.54 cm, to obtain Example 3. Weed-proof sheet.

[0102] The twill pattern angle α of the weed control sheet of Example 3 is 36° on average, the twist angle β is 17° on average, the angle difference between the twill pattern angle α and the twist angle β is 11-28°, and the difference rate is 52.5 (%) , satisfying the aforementioned formula (2). The coverage factor (CF) was 3964.

Abstract

The present invention provides a weed control sheet having a structure that is less likely to be damaged and capable of improving light-shielding properties. A weed control sheet (1), which has a twill weave or a satin weave comprising a surface-side base structure (10), a back-side base structure (20) and a weft yarn (31), the surface-side base structure (10) The first warp yarn (11) is included, the backside base fabric (20) includes a second warp yarn (21), and the weft yarn (31) connects the surface side base fabric (10) and the backside base fabric (20) to form a Double weave, and constitute: the first warp yarn (11) is the twisted yarn that comprises black spinning-dyed yarn, and the weft yarn (31) is the yarn that comprises black spinning-dyed yarn, and the twisting direction of the first warp yarn (11) It is consistent with the direction of the twill pattern shown in the base tissue (10) on the surface side.

Description

technical field [0001] The present invention relates to a grass-proof sheet and a method for manufacturing the grass-proof sheet. The grass-proof sheet has a twill weave or a satin weave including a surface-side base structure, a back-side base structure, and a weft yarn. The surface-side base structure includes The first warp yarn, the back side base weave includes the second warp yarn, and the weft yarn connects the front side base weave and the back side base weave to form a warp double weave. Background technique [0002] The weed control sheet has a weed control effect that blocks the light irradiated on the soil and suppresses the growth of plants. It is used to maintain the appearance of buildings and trees around the streets, or it is used to directly lay on the cultivation ground of orchards, vegetable gardens, etc. to adjust The growth environment of fruit trees and vegetables. [0003] Conventionally, a method of laying plastic sheets, rubber-coated fabric sheets...
