[0017] The utility model is described in detail below in combination with the drawings and examples.
[0018] The polyester fabric, as shown in Figure 1 And Figure 2 The utility model discloses a base layer 1, and the base layer 1 includes a plurality of breathable parts, and the breathable part is composed of a plurality of through holes 2, and the setting of the through hole 2 increases the passage of outside air directly passing through the fabric and entering the room, guarantees the air permeability of the whole structure, and the through hole 2 is integrally formed with the base layer 1, and the base layer 1 is set as the joint organization that openwork weave and plain weave are woven together, and the setting of the joint organization guarantees the stability of the formation and use of the through hole 2, and the side of the base layer 1 is sewn with the blocking piece 3 of the same position and the section area greater than the section area of the breathable part, so that the blocking piece 3 can completely block a plurality of through holes 2, reduce the situation that outside sunlight enters the room along the through hole 2, and guarantee the light shielding effect of the whole structure.
[0019] As shown in Figure 1 And Figure 2As shown, the blocking piece 3 includes a fixed section and a rotating section, the width of the fixed section is greater than the width of the rotating section, the width of the fixed section is three times the width of the rotating section, the supporting force of the fixed section to the rotating section is greater than the gravity of the rotating section, the gravity of the rotating section is reduced by increasing the length of the fixed section, thereby reducing the downward overturning of the rotating section under its own gravity, thereby ensuring the stable shading effect of the blocking piece 3. When external air flows through the through hole 2, the air will exert a pushing force on the rotating section to make it rotate away from the base layer 1, thereby enabling part of the through hole 2 to communicate with the indoor environment, and the external air can directly enter the indoor environment through the through hole 2. And because the width of the rotating section is small, the number of through holes 2 that communicate with the indoor air is also small, which reduces the light that enters the indoor environment through the through hole 2 while ensuring the structure's air permeability, so that the fabric can simultaneously consider sun protection and air permeability. The two sides of the fixed section are fixedly connected to the base layer 1 by stitching lines 8, the stitching lines 8 are arranged in a staggered manner with the through holes 2, and the stitching lines 8 are made of polyester yarn. The polyester yarn has good structural strength and wear resistance, and the characteristics of the polyester yarn are used to ensure the fixing strength of the stitching lines 8.
[0020] As shown in Figures 1-3 The two sides of the blocking piece 3 are formed with a plurality of support protrusions 4, which form a channel for external air to flow between the blocking piece 3 and the base layer 1. There is an air permeable space between adjacent support protrusions 4. While ensuring that the blocking piece 3 stably blocks external light, air can still enter the indoor environment along the channel and the air permeable space, ensuring the air permeability of the fabric. The blocking piece 3 and the support protrusions 4 are integrally formed. The blocking piece 3 is woven from blocking yarn 5. The blocking yarn 5 includes core yarn one 6 and core yarn two 7, which has a smaller diameter than the core yarn one 6. The core yarn one 6 and the core yarn two 7 are twisted by a twisting machine to form the blocking yarn 5. Therefore, when weaving, the larger diameter core yarn one 6 will form a plurality of support protrusions 4 on the base layer 1. The core yarn one 6 is twisted by a twisting machine from bamboo charcoal fiber. Bamboo charcoal fiber is usually dark gray in color. Therefore, the support protrusions 4 and the blocking piece 3 can stably absorb external light under the action of bamboo charcoal fiber. Bamboo charcoal fiber has good air permeability. The characteristics of bamboo charcoal fiber make the overall shading comfort of the structure. The core yarn two 7 is twisted by a twisting machine from polyester fiber. Polyester fiber has good light resistance and structural strength, so it can ensure the light resistance and durability of the blocking piece 3.
[0021] As shown in Figure 1 The base layer 1 is woven from polyester yarn. The polyester yarn is twisted by a twisting machine from polyester profiled fiber with a cross-sectional shape. The setting of the polyester profiled fiber ensures its light resistance while increasing the internal channel for air flow, further enhancing the air permeability of the fabric when in use.
[0022] As shown in Figures 1-3As shown, the polyester yarns are put into the weaving machine to form the base layer 1 and the through holes 2 by means of the openwork weave and the plain weave, the barrier yarns 5 are put into the weaving machine to form the barrier layer and the supporting protrusions 4, the barrier pieces 3 are cut along the thickness direction of the barrier layer by means of the laser cutting machine, and finally the barrier pieces 3 are sewn on the base layer 1 by means of the sewing machine using the sewing thread 8.
[0023] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical scheme falling within the idea of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application can also be considered as the protection scope of the present application.
