Description

Technical Field

[0001] This utility model relates to the textile field, and more specifically, to a breathable polyester fabric. Background Technology

[0002] Polyester fabric is one of the most common textile materials we use every day. It has the characteristics of high strength and abrasion resistance, which can ensure the overall lifespan and strength of textile products.

[0003] Due to its high strength and long lifespan, polyester fabric is widely used in curtains. To ensure its aesthetic appeal, some curtain fabrics feature hot stamping on both sides. Some curtains also require a certain degree of breathability, so the weaving density and thickness of the polyester fabric are reduced to improve breathability. However, the low weaving density and thickness of the polyester fabric result in insufficient tightness between the yarns, leading to poor adhesion of the hot stamping pattern.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a breathable polyester fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breathable polyester fabric, comprising a breathable layer and two surface layers located on both sides of the breathable layer, wherein the surface layer comprises a breathable part and a hot stamping part, the thickness of the breathable part is less than the thickness of the hot stamping part, and a plurality of grooves are formed on the side of the surface layer facing the breathable layer, the grooves being formed at the positions where the breathable parts are provided on the surface layer, and the projections of the breathable parts on the two surface layers onto the breathable layer overlap by at least 4 / 5.

[0007] The present invention is further configured such that: the surface layer is woven from warp yarns, weft yarns and skein yarns, the warp yarns include fine yarns located in the breathable part and coarse yarns located in the hot stamping part, the skein yarns are only provided on the breathable part, the fine yarns and skein yarns are twisted together to form skein warp, the weft yarns are connected in series with several skein warp and form several meshes on the breathable part, and the weft yarns and coarse yarns are woven on the hot stamping part to form a plain weave structure.

[0008] The present invention is further configured such that: the diameter of the roving is equal to the diameter of the weft yarn, the diameters of the skein and the yarn are equal, and the diameter of the roving is at least three times the diameter of the yarn.

[0009] The present invention is further configured such that the area of ​​the breathable part on the surface layer is larger than the area of ​​the hot stamping part on the surface layer, and that several bamboo joints are provided on both the fine yarn and the skein.

[0010] The present invention is further configured such that: a plurality of meshes are woven on the breathable layer, wherein the area of ​​the meshes is smaller than the area of ​​the holes.

[0011] The present invention is further configured such that: the breathable layer is woven from polyester yarn, the polyester yarn is made of low-elastic polyester filament twisted together, and the cross-section of the low-elastic polyester filament is Y-shaped.

[0012] In summary, this utility model has the following beneficial effects: the hot stamping part is thick and relatively flat, which ensures the adhesion of the hot stamping pattern, thereby guaranteeing the lifespan and durability of the hot stamping pattern. The yarn arrangement gaps on the breathable part and breathable layer of the surface layer are relatively large, which makes both the breathable part and the breathable layer have good breathability. Furthermore, the gaps between the breathable part and the breathable layer prevent the gaps on the breathable part and the breathable layer from accumulating and clogging. In addition, the breathable part occupies a large area on the surface layer, thereby ensuring the overall breathability of the polyester fabric. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A breathable polyester fabric, such as Figure 1As shown, the device includes a breathable layer 1 and two surface layers 2 located on either side of the breathable layer 1. The surface layer 2 includes a breathable portion 3 and a hot stamping portion 4. The thickness of the breathable portion 3 is less than the thickness of the hot stamping portion 4. Several grooves 5 are formed on the side of the surface layer 2 facing the breathable layer 1, at the locations where the breathable portions 3 are located. The projections of the breathable portions 3 on the two surface layers 2 onto the breathable layer 1 overlap by at least 4 / 5. The distribution area of ​​the breathable portions 3 on the surface layer 2 is greater than the distribution area of ​​the hot stamping portions 4 on the surface layer 2. The unevenness of the breathable portions 3 is greater than that of the hot stamping portions 4. The density of the yarn arrangement on the hot stamping portions 4 is greater than that on the breathable portions 3. The hot stamping portions 4 are thicker and relatively flat. Placing the hot stamping pattern on the hot stamping portions 4 ensures the adhesion of the hot stamping pattern, thereby guaranteeing the lifespan of the hot stamping pattern. The breathable parts 3 on the surface layer 2 and the yarn arrangement gaps on the breathable layer 1 are relatively large, resulting in good breathability for both the breathable parts 3 and the breathable layer 1. Furthermore, the gaps between the breathable parts 3 and the breathable layer 1 prevent the air pockets from accumulating and becoming clogged. The breathable parts 3 occupy a large area on the surface layer 2, thus ensuring the overall breathability of the polyester fabric. Preferably, during the lamination process, the breathable parts 3 and hot-stamping parts 4 on both surface layers 2 are arranged in a one-to-one correspondence. This arrangement ensures that the projections of the breathable parts 3 on the breathable layer 1 overlap. Since the requirement for the breathable parts 3 to correspond to each other is high during the lamination process, only a large overlap area is needed between the breathable parts 3 on the two surface layers 2. This ensures the breathability of the polyester fabric while also facilitating the lamination and production of polyester fabric.

[0019] like Figure 2 and Figure 3As shown, the surface layer 2 is woven from warp yarns, weft yarns 6, and skein yarns 7. The warp yarns include fine yarns 8 located in the breathable section 3 and roving yarns 9 located in the hot stamping section 4. The skein yarns 7 are only set on the breathable section 3. The fine yarns 8 and skein yarns 7 are twisted together to form skein warps. The weft yarns 6 are connected by several skein warps and form several meshes 10 on the breathable section 3. The weft yarns 6 and roving yarns 9 are woven on the hot stamping section 4 to form a plain weave structure. The distance between two adjacent fine yarns 8 is greater than the distance between two adjacent roving yarns 9. The hot stamping section 4 is a plain weave structure, and the surface of the plain weave structure is relatively flat, thus ensuring the firmness of the hot stamping pattern. The meshes 10 ensure the breathability of the breathable section 3. The diameter of the roving yarn 9 is equal to the diameter of the weft yarn 6, further ensuring the flatness of the hot stamping section 4. The diameters of the skein yarns 7 and fine yarns 8 are equal, and the diameter of the roving yarn 9 is at least three times the diameter of the fine yarns 8. The diameters of yarn 9 and yarn 8 differ significantly, ensuring that the thickness of the hot stamping section 4 is greater than that of the breathable section 3. Both yarn 8 and skein 7 have several slub joints, which increase the unevenness of the breathable section 3, making it easier for light to diffuse and reduce the amount of light passing through the curtain fabric. Several meshes 11 are woven into the breathable layer 1, with the area of ​​mesh 11 being smaller than that of mesh opening 10. The breathable layer 1 is also woven with warp and weft, ensuring its strength. The different breathable areas between mesh 11 and mesh opening 10 cause the breathable section 3 and breathable layer 1 on the polyester fabric to be misaligned with the mesh opening 10 and mesh opening 11, further reducing the amount of light passing through the breathable section 3. The warp, weft, and skein 7 are all made of twisted polyester fibers, ensuring the overall strength and lifespan of the two layers 2.

[0020] like Figure 3 As shown, the breathable layer 1 is woven from polyester yarn 12, which is made of low-elastic polyester filament twisted together. The cross-section of the low-elastic polyester filament is Y-shaped, and the irregular cross-sections have good cohesion, which can improve the fluffiness and breathability of the fiber, thereby ensuring the breathability of the breathable part 3. Moreover, the porosity of the Y-shaped cross-section fiber is 40%, which is more than twice that of the circular cross-section. These pores provide capillary channels for the conduction of sweat and moisture, which is conducive to moisture absorption and perspiration, thereby ensuring the dryness of the breathable layer 1 and reducing the impact of moisture on the breathability of the breathable layer 1.
