[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] As Figure 1As shown in Fig. 6, the present embodiment discloses a shading fabric, which comprises a first area 40, a second area 50 and a base fabric area 60. The fabric is formed by 32 warp yarns and 20 weft yarns in one cycle. The first 15-32 warp yarns and the first 1-20 weft yarns are interwoven to form the first area 40. In the interweaving of the first 15-32 warp yarns and the first 1-20 weft yarns, the first 15-22 warp yarns and the first 1-8 weft yarns are interwoven to form the first recessed area 402, and the first 15-22 warp yarns and the first 11-18 weft yarns are interwoven to form the first raised area 401. The first 25-32 warp yarns and the first 1-8 weft yarns are interwoven to form the first raised area 401, and the first 25-32 warp yarns and the first 11-18 weft yarns are interwoven to form the first recessed area 402. Therefore, the first raised areas 401 in each first area 40 are diagonally distributed, and the first recessed areas 402 in each first area 40 are diagonally distributed. The first raised areas 401 and the first recessed areas 402 are connected by the interweaving of the first 23-24 warp yarns and the first 1-20 weft yarns. The first 15-32 warp yarns and the first 9-10 and 19-20 weft yarns are interwoven. In the first area 40, the floats of the first raised areas 401 and the first recessed areas 402 are long, and in each first area 40, the connection between the first raised areas 401 and the first recessed areas 402 is the base fabric area 60, and the base fabric area 60 is a plain weave. Therefore, the first area 40 forms a concave-convex surface through the first raised areas 401 and the first recessed areas 402, and the light can be reflected multiple times at different angles, increasing the path length of the light on the surface of the fabric, thereby reducing the direct penetration of light and improving the shading effect of the fabric. Because the floats of the connected base fabric area 60 are short, and the floats of the first raised areas 401 and the first recessed areas 402 are long, in the first area 40, when the base fabric area 60 is connected to the first raised areas 401 and the first recessed areas 402, the long floats of the first raised areas 401 and the first recessed areas 402 will block the passage of light, thereby further increasing the shading of the fabric. In addition, due to the different floats, small air channels are formed between the first raised areas 401 and the first recessed areas 402, thereby increasing the air permeability of the fabric.

[0023] The first 1-10 warp yarns and the first 1-20 weft yarns are interwoven to form the second region 50, and in the interweaving of the first 1-10 warp yarns and the first 1-20 weft yarns, the first 1-4, 7-10 warp yarns and the first 1-8 weft yarns are interwoven to form the second rectangular area 502, the first 1-4, 7-10 warp yarns and the 11-18 weft yarns are interwoven to form the first rectangular area 501, and in the first rectangular area 501, the first 1-2, 7-8 warp yarns and the 11-18 weft yarns are interwoven to form the second convex area 5011, the third 3-4, 9-10 warp yarns and the 11-18 weft yarns are interwoven to form the second concave area 5012, and in the second rectangular area 502, the third 3-4, 9-10 warp yarns and the first 1-8 weft yarns are interwoven to form the second convex area 5011, the first 1-2, 7-8 warp yarns and the first 1-8 weft yarns are interwoven to form the second concave area 5012, so that not only the upper part of each second region 50 is the first rectangular area 501 and the lower part of each second region 50 is the second rectangular area 502, but also each first rectangular area 501 and each second rectangular area 502 include the second convex area 5011 and the second concave area 5012, the left side of the first rectangular area 501 is the second convex area 5011, the right side of the first rectangular area 501 is the second concave area 5012, the left side of the second rectangular area 502 is the second concave area 5012, and the right side of the second rectangular area 502 is the second convex area 5011, so that the second convex area 5011 and the second concave area 5012 are arranged in an up-and-down staggered manner, and because the staggered arrangement structure formed by the second convex area 5011 and the second concave area 5012 increases the concave-convex structure of the fabric, when light is irradiated, the reflection and scattering of light are increased, and the direct transmission of light is reduced, thereby increasing the light-shielding property of the fabric, and because in the second region 50, along the width direction of the fabric, the first rectangular area 501 and the second rectangular area 502 are connected by the base fabric area 60 formed by the interweaving of the fifth 5-6 warp yarns and the first 1-20 weft yarns, and along the length direction of the fabric, the first rectangular area 501 and the second rectangular area 502 are connected by the base fabric area 60 formed by the interweaving of the first 1-10 warp yarns and the ninth 9-10, 19-20 weft yarns, so that in the same second region 50, when the base fabric area 60 is connected with the second convex area 5011 and the second concave area 5012, the long floats of the second convex area 5011 and the second concave area 5012 can block the passage of light, further increasing the light-shielding property of the fabric, and because of the different floats, a small air flow is formed between the second convex area 5011 and the second concave area 5012, thereby increasing the air permeability of the fabric.

[0024] The 11th-14th warp yarns are interwoven with the 1st-20th weft yarns to form the base fabric area 60 connecting the first area 40 and the second area 50. Since the base fabric area 60 is respectively connected with the first area 40 and the second area 50, when the base fabric area 60 is connected with the first area 40 and the second area 50, the float length of the first area 40 and the second area 50 will partially cover the float length of the base fabric area 60, so that the base fabric area 60 will not be transparent to light, but the air permeability of the fabric is increased.

[0025] Since the first raised area 401 and the first recessed area 402 are both formed by interweaving 8 warp yarns and 8 weft yarns, the first raised area 401 and the first recessed area 402 are square-shaped. Since the second raised area 5011 and the second recessed area 5012 are both formed by interweaving 2 warp yarns and 9 weft yarns, the second raised area 5011 and the second recessed area 5012 are rectangular-shaped. Since the first rectangular area 501 and the second rectangular area 502 are both formed by interweaving 4 warp yarns and 9 weft yarns, the first rectangular area 501 and the second rectangular area 502 are rectangular-shaped. Therefore, when the first area 40 and the second area 50 are interwoven and connected, a rectangular grid and a square grid are alternately arranged, which forms a rough surface. Since the rectangular grid and the square grid have different reflection angles for light, multi-angle reflection and scattering are formed, thereby increasing the light-shielding property of the fabric. Since the float length of the second raised area 5011 and the second recessed area 5012 is long, the degree of the raised area can be increased, thereby making the fabric structure more compact. Since the float length of the first raised area 401 and the first recessed area 402 is short, and the interweaving times of the warp yarns and the weft yarns are uniform, the fabric forms a stable skeleton structure. Therefore, when the first area 40 and the second area 50 are connected, the stable structures complement each other, thereby improving the overall structural stability and wear resistance of the fabric.

[0026] Because the first convex region 401, the first concave region 402, the second convex region 5011 and the second concave region 5012 are all formed by interweaving 8 weft yarns, the length of the first convex region 401 and the first concave region 402 is the same as the length of the second convex region 5011 and the second concave region 5012, because the first convex region 401 and the first concave region 402 are interwoven by 8 warp yarns, while the second convex region 5011 and the second concave region 5012 are interwoven by 2 warp yarns, and the first rectangular region 501 and the second rectangular region 502 are interwoven by 4 warp yarns, therefore the width of the first convex region 401 and the first concave region 402 is 2 times the width of the first rectangular region 501 and the second rectangular region 502, and the width of the first convex region 401 and the first concave region 402 is 4 times the width of the second convex region 5011 and the second concave region 5012, and in the first region 40 and the second region 50, the base cloth region 60 is interwoven by 2 warp yarns or 2 weft yarns, therefore the width of the base cloth region 60 in each first region 40 and each second region 50 is the same as the width of the second convex region 5011 and the second concave region 5012, and the base cloth region 60 in each first region 40 and each second region 50 is interwoven by warp and weft yarns to form a small channel, thereby increasing the air permeability of the fabric, and the yarn is interwoven by plain weave in the base cloth region 60 in each first region 40 and each second region 50, thereby increasing the structural stability of the first region 40 and the second region 50, thereby reducing the hooking phenomenon of the long floats in the first region 40 and the second region 50.

[0027] Along the width direction of the fabric, the first region 40 and the second region 50 are arranged alternately, the first region 40 is connected with the base cloth region 60, the second region 50 is connected with the base cloth region 60, each first region 40 includes two first convex regions 401 and two first concave regions 402, each second region 50 includes two first rectangular regions 501 and two second rectangular regions 502, the first convex region 401 and the first concave region 402 are square, the first rectangular region 501 and the second rectangular region 502 are rectangular, the interweaving points in the square of the first region 40 are uniformly distributed, the friction between the fibers is larger, which can reduce the slip of the fibers, while the long floats in the rectangular of the second region 50 are long, the friction between the fibers is smaller, which can increase the wear resistance of the fabric, and the first region 40 and the second region 50 are interwoven, the first region 40 and the second region 50 can form more comprehensive reflection and scattering of light, increase the reflection path length of light, thereby increasing the light-shielding property of the fabric, and the first region 40 and the second region 50 are both connected with the base cloth region 60, and the first region 40 and the second region 50 are both concave and convex, therefore the insertion of the base cloth region 60 increases the small channels between the fabrics, thereby increasing the air permeability of the fabric.

It should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
