Description

Technical Field

[0001] The utility model relates to the field of textiles, and more specifically, to a wear-resistant curtain fabric. Background Art

[0002] Curtain fabric is a decorative material used for making curtains. It is designed and sewn, and is usually used for window decoration in indoor spaces such as homes and offices.

[0003] In order to ensure the overall wear resistance and service life of the existing curtain fabric, the curtain fabric is woven with polyester yarn with better wear resistance. And in order to ensure that the curtain fabric has relatively good light-shielding performance, the weaving density of the curtain fabric is relatively high, making the gap between the yarns relatively small, so that the amount of sunlight passing through the curtain fabric is relatively small. However, the air permeability of the polyester yarn itself is weak, and the overall weaving density of the curtain fabric is relatively high, resulting in weak air permeability of the curtain fabric as a whole.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a wear-resistant curtain fabric.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a wear-resistant curtain fabric, including an outer layer and an inner layer. Alternately arranged arc segments and straight segments are formed on the inner layer. A cavity is formed between the arc segment and the inner layer. A plurality of through holes communicating with the cavity are opened on the outer layer. All of the plurality of through holes are arranged close to the edge of the arc segment. The length of the arc segment along the warp direction of the inner layer is at least three times the diameter of the through hole. The arc segment includes a light-shielding portion and a breathable portion. The area of the light-shielding portion is twice that of the breathable portion, and the projection of the light-shielding portion on the inner layer covers the position where the through holes are arranged on the inner layer.

[0007] The present utility model is further arranged as follows: Alignment portions formed by weaving colored yarns are provided on both the straight segment and the outer layer.

[0008] The present utility model is further arranged as follows: The outer layer is woven with polyester yarn, and the weaving density of the outer layer is 180 - 200 threads per inch.

[0009] The present utility model is further arranged as follows: The inner layer is formed by warp and weft weaving of warp yarns and weft yarns. The weft yarns include breathable yarns and shielding yarns. Among them, the weft yarns located on the light-shielding portion are shielding yarns, and the weft yarns located on the breathable portion are breathable yarns. The distance between adjacent breathable yarns is greater than the distance between adjacent shielding yarns.

[0010] The present utility model is further configured such that: both the warp yarn and the shielding yarn are formed by winding slub yarns, and the slub yarns are twisted from low-elastic polyester filaments.

[0011] The present utility model is further configured such that: the breathable yarn is twisted from cotton fibers.

[0012] In summary, the present utility model has the following beneficial effects: The outer layer of the curtain fabric faces away from the interior of the room, and a plurality of through holes are close to the lower end of the arc section. Such a setting enables sunlight to directly irradiate on the light-shielding part after passing through the through holes. The light-shielding part has a good light-shielding effect, making it difficult for sunlight to penetrate the light-shielding part. The area of the light-shielding part is relatively large. Even if sunlight obliquely enters the cavity, the sunlight still shines on the light-shielding part. External air can enter the cavity through the through holes and then interact with the internal air through the breathable part, thereby enabling the curtain fabric to have a certain air permeability and ensuring the air permeability of the curtain fabric.

[0017] The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] A wear-resistant curtain fabric, such as Figure 1As shown in the figure, it includes an outer layer 1 and an inner layer 2. Alternately arranged arc segments and straight segments are formed on the inner layer 2. A cavity is formed between the arc segments and the inner layer 2. A number of through holes 3 are provided on the outer layer 1 and are communicated with the cavity. A number of through holes 3 are all arranged close to the edge of the arc segment. The length of the arc segment along the meridional direction of the inner layer 2 is at least three times the diameter of the through hole 3. In this embodiment, the length of the arc segment is three times the diameter of the through hole 3. The arc segment includes a light-shielding portion 4 and a breathable portion 5. The area of the light-shielding portion 4 is twice that of the breathable portion 5. The projection of the light-shielding portion 4 on the inner layer 2 covers the position where the through hole 3 is provided on the inner layer 2. The outer layer 1 of the curtain fabric faces away from the interior. A number of through holes 3 are close to the lower end of the arc segment. Such a setting enables sunlight to directly irradiate on the light-shielding portion 4 after passing through the through hole 3. The light-shielding portion 4 has a good light-shielding effect, making it difficult for sunlight to penetrate the light-shielding portion 4. The area of the light-shielding portion 4 is large. Even if sunlight obliquely enters the cavity from top to bottom, the sunlight also shines on the light-shielding portion 4 of the arc segment close to the straight segment. The inner wall of the arc segment is arc-shaped, so that sunlight is easily reflected multiple times in the cavity, thereby reducing the intensity of sunlight, so that even if the sunlight passes through the curtain fabric, its intensity will not be too high. External air can enter the cavity through the through hole 3 and then interact with the internal air through the breathable portion 5, so that the curtain fabric has a certain air permeability, ensuring the air permeability of the curtain fabric. The area of the breathable portion 5 is half of the area of the light-shielding portion 4, so that the breathable portion 5 still has a certain area, ensuring a large breathable area on the arc segment while meeting the light-shielding performance.

[0019] As Figure 2 and Figure 3 shown in the figure, alignment portions 6 formed by weaving colored yarns are provided on both the straight segment and the outer layer 1. During the process of laminating the inner layer 2 and the outer layer 1, the alignment portion 6 on the straight segment is aligned with the alignment portion 6 on the outer layer 1, thereby facilitating the lamination of the inner layer 2 and the outer layer 1. The setting of the colored yarn makes it easy to distinguish the alignment portions 6 on the inner layer 2 and the outer layer 1. The outer layer 1 is woven from polyester yarn. The weaving density of the outer layer 1 is 180 - 200 threads per inch. The weaving density of the outer layer 1 is relatively high and the polyester yarn itself has the characteristics of high strength and good wear resistance, thus ensuring the light-shielding ability and wear resistance of the outer layer 1. The inner layer 2 is formed by warp knitting and weft knitting with warp yarns 7 and weft yarns. The weft yarns include breathable yarns 8 and shielding yarns 9. Among them, the weft yarns located on the light-shielding portion 4 are shielding yarns 9, and the weft yarns located on the breathable portion 5 are breathable yarns 8. The distance between adjacent breathable yarns 8 is greater than the distance between adjacent shielding yarns 9. A number of through holes are woven on the breathable portion 5. The large spacing between the weft yarns and the setting of the through holes in the breathable portion 5 ensure the air permeability of the breathable portion 5. The arrangement density of the shielding yarns 9 in the light-shielding portion 4 is large, making the gap between the shielding yarns 9 small and the shielding yarns 9 having a certain light-shielding ability, thus ensuring the light-shielding ability of the light-shielding portion 4. The weft yarns on the straight segment are also shielding yarns 9, making the weaving density of the straight segment relatively high, thus facilitating the connection between the straight segment and the outer layer 1.

[0020] As Figure 3 shown, both the warp yarn 7 and the shielding yarn 9 are formed by winding slub yarns. The slub yarns are made by twisting low-elastic polyester filaments. The low-elastic polyester filaments have the characteristics of high strength and low elasticity, making the structure of the arc segment relatively stiff and ensuring the stability of the cavity. The low-elastic polyester filaments also have good light-shielding ability, thus ensuring the light-shielding performance of the light-shielding part 4. There are slubs on the slub yarns, making the surface of the light-shielding part 4 uneven, so that sunlight is prone to diffuse reflection when shining on the light-shielding part 4, facilitating the weakening of the sunlight intensity. The breathable yarn 8 is made by twisting cotton fibers. The cotton fibers have good breathable performance, so that air can easily pass through the breathable yarn 8, ensuring the breathable performance of the breathable part 5.

[0021] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
