[0066] figure 1 It is a partial enlarged cross-sectional view of the weed control sheet 101 of the first embodiment. figure 2 It is a structure diagram of the weed structure which the weed control sheet 101 of 1st Embodiment has. It should be noted, figure 1 The cross-sectional view of the diagram exaggerates the fineness and spacing of the yarns for easy understanding, and does not strictly reflect the actual scale and positional relationship. In addition, in figure 2 In the organization diagram of , the arrangement of organizations in the horizontal direction is called "row", and the arrangement of organizations in the vertical direction is called "column".
[0067] Such as figure 1 and figure 2 As shown, the weed control sheet 101 has a weed 110 on the front side including a first warp yarn 111, a weave 120 on the back side including a second warp yarn 121, and the weed 110 on the front side is connected to the weave 120 on the back side to form a double. The weft ...

[0087] image 3 It is an example of the structure diagram of the weed structure which the weed control sheet 201 of 2nd Embodiment has. Figure 4 It is a partially enlarged cross-sectional view of the weed texture of the grass-proof sheet 201 of the second embodiment. exist image 3 and Figure 4 In the grass-proof sheet 201 of the second embodiment shown, the 3 / 1 twill weave of the warp and weft double-layer fabric is used, and not only the warp but also the weft also use two kinds of weft yarns, that is, the first weft yarn 231a and the second weft yarn 231b. Here, according to image 3 , in the odd-numbered columns, the first warp yarns 211 constituting the ground weave 210 on the surface side are shown in gray, and the first weft yarns 231a are shown in white. The second warp yarns 221 constituting the ground weave 220 on the back side are shown in white in the even-numbered columns, and the second weft yarns 231b are shown in gray in each column. In addition, not onl...
Embodiment 1
[0096] Black dyed processed yarn 167dtex / 36f (manufactured by Nan Ya Plastics Corporation (hereinafter referred to as Nanya)) of polyester was used for the first warp yarn, and white semi-dull (SD) processed yarn 167dtex of polyester was used for the second warp yarn / 36f (manufactured in South Asia), using polyester black spun-dyed processed yarn 167dtex / 36f (manufactured in South Asia) for the weft yarn to form a warp yarn double-layer fabric to obtain the grass-proof sheet with a deformed satin weave in Example 1. In the weed control sheet of Example 1, both the weeds on the surface side and the weeds on the back side had three floating yarns, and the length of the floating yarns was 1.24 mm. In addition, the blending degree of the warp was 40247, the blending degree of the weft was 11356, and the blending degree ratio was 3.54.
