[0002] In related technologies, curtain fabrics achieve their light-blocking function by using blackout yarns in the finishing process. Although some related technologies use blackout curtains with black silk interlayers, conventional black silk only achieves light blocking through physical weaving, which can lead to problems such as the structure becoming loose after repeated washing. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide a third thread with a fusible connection that can improve the structural stability of curtain fabric.

[0005] The curtain fabric according to an embodiment of the present invention includes a plurality of first threads, a plurality of second threads, and a plurality of third threads. The plurality of first threads, the plurality of second threads, and the plurality of third threads are woven into a fabric structure.

[0015] In some examples of this utility model, the ratio of the radial dimension of the core to the radial dimension of the third wire is greater than or equal to 10% and less than or equal to 80%.

[0016] In some examples of this invention, the sheath uniformly wraps around the core wire.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] Combination Figures 1 to 7 According to an embodiment of the present invention, the curtain fabric 100 includes a plurality of first threads 10, a plurality of second threads 20, and a plurality of third threads 30. The plurality of first threads 10, second threads 20, and third threads 30 are woven into a fabric structure. The plurality of third threads 30 are disposed between the plurality of first threads 10 and second threads 20. The first threads 10 and second threads 20 are cross-woven to wrap around the third threads 30. The third threads 30 are heat-melted light-blocking agents. For example, the third threads 30 contain a light-blocking hot-melt adhesive film or a light-blocking hot-melt adhesive mesh. Thus, the third threads 30 can be heated and melted, and have a light-blocking effect. The third threads 30 include a core 31 and a sheath 32 wrapping the core 31. The melting temperature of the sheath 32 is lower than that of the core 31. Therefore, when heated and melted, the sheath 32 melts while the core 31, with its higher melting temperature, does not melt, thus allowing the core 31 to provide some support. The sheaths 32 of the plurality of third threads 30 are fused together after being heated to a preset temperature.

[0033] Specifically, the core 31 of the third line 30 plays a supporting role inside the sheath 32. The sheath 32 can be fused together during processing, so that the sheaths 32 of multiple third lines 30 are connected to form a surface. After curing, multiple third lines 30 together form a film or layered structure between the first line 10 and the second line 20, which helps to improve structural stability and makes it difficult for light to penetrate from the gaps between the lines, thus achieving a light-blocking effect.

[0034] Furthermore, compared to the structure of braided threads, the third thread 30 in this application is fused together to form a whole, resulting in better structural stability. It is less likely to loosen after washing, which helps to improve structural stability. Therefore, under the same structural strength or the same light-blocking effect, the number of third threads 30 in this application can be reduced compared with related technologies, thereby reducing the weight of the curtain fabric 100.

[0035] According to the embodiment of the present invention, the curtain fabric 100 has a third thread 30 with a core 31 and a sheath 32 provided between a plurality of first threads 10 and a plurality of second threads 20. The sheath 32 of the third thread 30 can be fused together to achieve a light-blocking effect, and the third thread 30 can provide a supporting effect between the first threads 10 and the second threads 20, thereby improving the structural stability.

[0036] like Figure 1 This shows the state where the third line is not fused together, as shown. Figure 3 The state after the third line is fused together is shown.

[0037] Combination Figure 1 and Figure 3 In some embodiments of this utility model, multiple first threads 10, multiple second threads 20, and multiple third threads 30 are woven into a double-warp single-weft or double-warp double-weft three-layer fabric structure. The first threads 10, second threads 20, and third threads 30, after being woven, can form a three-layer fabric structure, wherein the first threads 10 and second threads 20 are the outer layers of the fabric, and threads that improve breathability or aesthetics can be selected. Multiple first threads 10 are woven to form the outer layer 110 of the curtain fabric 100, multiple second threads 20 are woven to form the bottom layer 120 of the curtain fabric 100, and multiple third threads 30 are fused together to form the middle layer 130.

[0038] Specifically, when curtain fabric 100 is double-warp and single-weft, each warp yarn group can be composed of two yarns running side by side, and each weft yarn group can be woven with one yarn interlaced. This improves the tensile strength of curtain fabric 100 in the longitudinal or warp direction, thus increasing its overall strength. The single weft results in a lower density in the transverse or weft direction, improving breathability and making the fabric feel softer. Furthermore, the reduced weft yarn usage saves material. The double-warp, single-weft three-layer fabric structure is suitable for applications requiring high drape but not excessive weight. In the double-warp, double-weft three-layer fabric structure, each warp yarn group can be composed of two yarns running side by side, and each weft yarn group can also be woven with two yarns running side by side. This doubles the warp and weft lengths, resulting in a thicker, denser fabric with better light-blocking properties, stronger structural stability, and greater wrinkle resistance.

[0039] Combination Figure 2 and Figure 4 In some embodiments of this utility model, the first line 10 and the second line 20 are configured to extend along a first direction. For example, the first line 10 is configured as a wavy line extending along the first direction, the second line 20 is configured as a wavy line extending along the first direction, a plurality of first lines 10 and a plurality of second lines 20 are staggered along a second direction and have a plurality of intersections distributed along the first direction, and a third line 30 extends along the second direction and is disposed between adjacent intersections, with at least one third line 30 disposed between adjacent intersections, and the first direction and the second direction are perpendicular. Specifically, the staggered distribution of the first lines 10 and the second lines 20 can improve the tightness of the connection between the first lines 10 and the second lines 20, and the wavy first lines 10 and the second lines 20 can form a receiving space between the two intersections of the first lines 10 and the second lines 20 after they intersect, and the third line 30 can be disposed in the receiving space between the two intersections, which is beneficial to improving the compactness of the structure, and the third line 30 can be interwoven between the first lines 10 and the second lines 20, thereby reducing the light passing through the second lines 20 from the first lines 10, thereby improving the light-blocking effect.

[0040] In some embodiments of this utility model, the number of third lines 30 between each adjacent intersection is the same, which helps to improve the consistency of the curtain fabric 100 structure and facilitates manufacturing.

[0041] Alternatively, the number of third lines 30 varies between multiple intersection points; the number of third lines 30 can be a single group or a group of multiple lines. Specifically, combining... Figure 2In some embodiments of this utility model, the multiple intersection points include adjacent first intersection point 201, second intersection point 202, and third intersection point 203. The number of third lines 30 between the first intersection point 201 and the second intersection point 202 is different from the number of third lines 30 between the second intersection point 202 and the third intersection point 203. For example, the number of third lines 30 between the first intersection point 201 and the second intersection point 202 may be greater than or less than the number of third lines 30 between the second intersection point 202 or the third intersection point 203. That is, the number of third lines 30 between the multiple intersection points can be different, and the different numbers of third lines 30 can be arranged alternately.

[0042] In some embodiments of this utility model, a third line 30 is provided between the first intersection point 201 and the second intersection point 202, and two third lines 30 are provided between the second intersection point 202 and the third intersection point 203. The one and two third lines 30 can be arranged alternately along a first direction; that is, in the first direction, one third line 30 is provided between the first intersection point 201 and the second intersection point 202, two third lines 30 are provided between the second intersection point 202 and the third intersection point 203, one third line 30 is provided between the third intersection point 203 and the fourth intersection point, two third lines 30 are provided between the fourth intersection point and the fifth intersection point, and so on. This increases the number of third lines 30 and creates a texture on the curtain fabric 100, which helps improve the structural stability, light-blocking ability, and aesthetics of the curtain fabric 100. Of course, the third line 30 can also be arranged in other ways. For example, a third line 30 is provided between the first intersection 201 and the second intersection 202, two third lines 30 are provided between the second intersection 202 and the third intersection 203, three third lines 30 are provided between the third intersection 203 and the fourth intersection, and so on. This utility model is not limited to this.

[0043] Combination Figure 4 In some embodiments of this invention, the sheaths 32 of multiple third threads 30 are fused together to form a continuous film structure. This film structure can be a light-blocking film structure, providing a light-blocking effect. Specifically, the multiple sheaths 32 are fused into a film, so that the multiple third threads 30 form a whole after melting. On the one hand, this can better block light and improve the light-blocking properties of the fabric; on the other hand, it can improve the structural stability of the multiple third threads 30, preventing them from loosening during washing.

[0044] In some embodiments of this utility model, the wire core 31 forms a support skeleton after the wire sheath 32 is melted. The support skeleton is used to support the molten wire sheath 32 to form a continuous light-shielding film structure, thereby improving the structural stability of the light-shielding film structure.

[0045] In some embodiments of this invention, the ratio of the thickness of the multiple third threads 30 after fusion to the thickness of the curtain fabric 100 is greater than or equal to 0.1 and less than or equal to 1. This ratio affects the functionality of the curtain fabric 100. Specifically, when the ratio is small, the thickness of the multiple third threads 30 after fusion is smaller relative to the thickness of the curtain fabric 100, meaning the intermediate layer 130 formed by the multiple third threads 30 in the middle is thinner, resulting in weaker light-blocking effect. However, the first thread 10 and the second thread 20 have a certain thickness, leading to better breathability, softness, and lightness. When the ratio is large, the thickness of the multiple third threads 30 after fusion is larger relative to the thickness of the curtain fabric 100, resulting in a thicker intermediate layer 130 and stronger light-blocking effect. When the ratio is 1, the third threads 30, after fusion, can form a single unit with the first thread 10 and the second thread 20. Therefore, this ratio can be adjusted according to the actual application scenario to improve practicality. Optionally, the ratio of the thickness of the multiple third lines 30 after fusion bonding to the thickness of the curtain fabric 100 can be 0.2, 0.5, 0.6, 0.8, 0.9, etc.

[0046] Combination Figure 2 In some embodiments of this utility model, the ratio of the radial dimension of the core 31 to the radial dimension of the third thread 30 is greater than or equal to 10% and less than or equal to 80%. The radial dimension of the third thread 30 can be approximated as the thickness of the film-like structure formed by the fusion of the sheaths 32 of multiple third threads 30. Specifically, this ratio is the proportion of the thickness of the core 31 to the thickness of the third thread 30. If the ratio is small, the thickness of the core 31 is small, and the supporting effect of the core 31 on the third thread 30 will be weakened; if the ratio is large, the thickness of the core 31 is large, which may result in poor softness of the curtain fabric 100. Furthermore, the radial dimension of the sheaths 32 will also be small, and the structural stability after the sheaths 32 are fused together may be weakened. Therefore, by reasonably setting the radial dimension of the core 31 to the radial dimension of the third thread 30... The ratio can improve the structural stability of curtain fabric by 100%.

[0047] Combination Figure 6 In some embodiments of this utility model, the sheath 32 uniformly wraps the core 31, which can improve the structural stability of the third wire 30. In particular, after the sheath 32 is melted, the overall structural stability of the third wire 30 can be improved.

[0048] In some embodiments of this utility model, the weaving density of the first thread 10 and the second thread 20 is greater than or equal to 50 threads / cm and less than or equal to 500 threads / cm, and the weaving density of the third thread 30 is greater than or equal to 10 threads / cm and less than or equal to 50 threads / cm. That is, the weaving density of the first thread 10 and the second thread 20 is greater than the weaving density of the third thread 30. This allows the first thread 10 and the second thread 20 to more firmly wrap the third thread 30, and since the first thread 10 and the second thread 20 are exposed and facing the user, the higher weaving density and smaller gaps enhance softness and aesthetics. The lower weaving density of the third thread 30 facilitates the lightweighting of the curtain fabric 100. Specifically, the first thread 10 and the second thread 20 can be weft threads, and the third thread 30 can be warp threads; alternatively, the first thread 10 and the second thread 20 can be warp threads, and the third thread 30 can be a weft thread. Figure 1 This illustrates a scenario where the first line 10 and the second line 20 are latitudinal lines, and the third line 30 is a radial line. For example... Figure 7 This illustrates the case where the first line 10 and the second line 20 are radial lines, and the third line 30 is a latitudinal line.

[0049] When the first thread 10 and the second thread 20 are radial threads or warp yarns, the weaving density of the first thread 10 and the second thread 20 is greater than or equal to 50 threads / cm and less than or equal to 500 threads / cm; when the first thread 10 and the second thread 20 are weft threads or weft yarns, the weaving density of the first thread 10 and the second thread 20 is greater than or equal to 10 threads / cm and less than or equal to 100 threads / cm.

[0050] Specifically, the appropriate weaving density of the first thread 10 and the second thread 20 can balance the relationship between the quality and cost of the curtain fabric 100, or the weaving density can be set according to whether the first thread 10 and the second thread 20 are radial or weft threads. For example, the weaving density of the first thread 10 and the second thread 20 can be 80 threads / cm, or 200 threads / cm, or 300 threads / cm, etc. The appropriate weaving density of the third thread 30 can balance the relationship between the structural stability, light-blocking properties, and weight of the curtain fabric 100. For example, the weaving density of the third thread 30 can be 20 threads / cm, or 30 threads / cm, or 40 threads / cm, etc.

[0051] According to one embodiment of the present invention, the curtain fabric 100 has a weaving density of 150 threads / cm for the first thread 10 and the second thread 20, and a weaving density of 25 threads / cm for the third thread 30.

[0052] In some embodiments of this utility model, the first thread 10 and the second thread 20 constitute the outer layer of the fabric, which can directly contact the user. Therefore, the first thread 10 and the second thread 20 can be set to a softer form or set to a colored form, and after weaving, they form a pattern to enhance the aesthetics.

[0053] In some embodiments of this utility model, the sheath 32 is a tubular structure made of the same material as the core 31 but with a lower melting point, and wraps around the core 31. This improves the wrapping effect of the sheath 32 on the core 31 and enhances the support effect of the core 31 on the sheath 32. Thus, after the sheath 32 melts, the core 31 can provide better support within the sheath 32. Furthermore, the outer periphery of the tubular structure is arc-shaped, which improves structural stability and compactness, facilitating the lightweight and softness of the curtain fabric 100. The lower melting point of the sheath 32 compared to the core 31 makes it easier to fuse the sheath 32 during manufacturing, while the core 31 does not melt, ensuring support within the sheath 32.

[0054] Furthermore, in some embodiments of this utility model, the melting point of the wire sheath 32 is greater than or equal to 60°C and less than or equal to 150°C, and the melting point of the wire core 31 is greater than or equal to 200°C and less than or equal to 300°C. That is, the melting point of the wire core 31 is greater than the melting point of the wire sheath 32, so that only the wire sheath 32 melts during fusion bonding. The melting point of the wire core 31 should be at least 50°C greater than the melting point of the wire sheath 32. For example, the melting point of the wire sheath 32 can be 90°C, 100°C, or 140°C, etc. The melting point of the wire core 31 can be 220°C, 240°C, or 280°C, etc. In one specific embodiment of this utility model, the melting point of the wire sheath 32 is 120°C, and the melting point of the wire core 31 can be 260°C.

[0055] In some embodiments of this utility model, the first thread 10 and / or the second thread 20 are made of conventional textile materials, which facilitates manufacturing, reduces costs, improves the practicality of the curtain fabric 100, and enhances the versatility of the curtain fabric 100.

[0056] In some embodiments of this utility model, the third thread 30 adopts a black silk core structure. The black silk has a light absorption rate and can play a light-blocking role, thereby improving the light-blocking performance of the curtain fabric 100, so that the curtain fabric 100 can be used in curtains and other scenarios that require light blocking.

[0057] In some embodiments of this invention, the sheath 32 and the core 31 are made of the same material but with different melting points: polyester or nylon. Specifically, polyester is less expensive, more durable, easier to care for, and more convenient for users. High-density polyester can naturally block light (e.g., 150 threads / cm warp density), and after being laminated with black yarn, it can achieve 100% light blocking. Nylon has a higher resilience, stronger tensile strength, and is softer and more comfortable; in practical applications, it can be selected according to the user's usage scenario or habits.

[0058] In some embodiments of this utility model, the first thread 10 is set as 75D polyester fully drawn yarn or nylon fully drawn yarn, the second thread 20 is set as 75D cationic composite yarn, and the third thread 30 is 300D core-sheath yarn.

[0059] In some embodiments of this utility model, after multiple first threads 10, multiple second threads 20, and multiple third threads 30 are braided, they are heated at a preset temperature for a predetermined time to melt the sheath 32 of the multiple third threads 30. The preset temperature is higher than the melting point of the sheath 32 but lower than the melting point of the core 31, and the predetermined time is greater than or equal to 5 seconds and less than or equal to 600 seconds. Specifically, a shorter heating time may result in the sheath 32 not melting or a poor fusion connection; a longer heating time may also result in a poor fusion connection or damage to the core 31 or the first threads 10 and second threads 20. Furthermore, a suitable heating time can improve processing efficiency. Therefore, by setting a suitable predetermined time, the fusion connection of the third threads 30 can be achieved, and the connection is stable, which is beneficial for improving processing efficiency.

[0060] According to the present utility model, the curtain includes the aforementioned curtain fabric 100. By applying the aforementioned curtain fabric 100, a light-blocking effect can be achieved, and structural stability can be improved.

[0061] The following description, with reference to the accompanying drawings, describes a specific embodiment of the curtain fabric 100 and the curtain.

[0062] According to an embodiment of the present invention, the curtain fabric 100 includes a surface layer 110 woven from a plurality of first threads 10 and a bottom layer 120 woven from a plurality of second threads 20. A plurality of third threads 30 are disposed between the surface layer 110 and the bottom layer 120. Each third thread 30 includes a core 31 and a sheath 32 wrapped around the core 31. The sheaths 32 of the plurality of third threads 30 are fused together to form an intermediate layer 130 disposed between the surface layer 110 and the bottom layer 120. The surface layer 110 and the bottom layer 120 are outer layers made of conventional textile materials, while the intermediate layer 130 uses black yarn with a core 31 structure. (See also:) Figure 7 The hot melt yarn (i.e., the third yarn 30) can be used as the weft yarn. The core yarn 31 is made of the same textile material with different melting points (e.g., the sheath 32: modified polyester with a melting point of 120℃; the core yarn 31: conventional polyester with a melting point of 260℃). The material includes, but is not limited to, polyester and nylon. The diameter of the core yarn 31 accounts for 10-80%, and the sheath 32 is evenly wrapped around the core yarn 31.

[0063] Specifically, conventional yarn consists of two layers: an inner sheath and a core. The core material is consistent (PET, PE, PP, PA, etc. are all acceptable), but their melting points differ. For example, the core may be made of conventional polyester with a melting point of around 260 degrees Celsius, while the sheath may be made of polyester with a melting point of 120 degrees Celsius, forming a core yarn resembling an egg roll. In this application, the sheath 32 of the third yarn 30 can be fused together to achieve a yarn-to-surface structure. Specifically, after weaving, the yarns in each layer of the fabric have a yarn-to-yarn connection structure. However, after high temperature treatment, the sheath 32 of the third yarn 30 melts and then undergoes conventional processing. The melted material then solidifies again, and the original yarn structure transforms into a surface structure.

[0064] In actual processing, the yarn sheath 32 is melted through dyeing (80-120℃) or finishing (130-180℃) processes. The molten yarn sheath 32 forms a continuous film-like structure that wraps around the core layer, while the unmelted core layer maintains the fiber morphology, forming a "reinforced concrete" composite structure. Specifically, the core 31 structure is used to prevent the yarn from completely melting after melting, thus preventing it from penetrating to the fabric surface layer 110. The presence of unmelted core threads also allows the solidified black film to have a certain degree of extensibility and a more uniform film. Because the third thread 30 forms a skeleton after melting, it improves the support effect and ensures that it will not be washed away by the dyeing liquid. Alternatively, the yarn sheath 32 can also be melted using a separate heating device.

[0065] The curtain fabric 100 implemented by this utility model, after testing, has a light-blocking rate of over 99.5% and a light-blocking weight of over 10%; the warp breaking strength retention rate is ≥85%; and the washability is improved (the light-blocking rate does not decrease after 100 washes).

[0066] More specifically, the warp and weft yarns are as follows: the outer layer 110 uses 75D polyester FDY, the middle layer 130 uses 300D core yarn 31 (core yarn 31: conventional polyester; sheath yarn 32: low melting point polyester 120 degrees), and the bottom layer is 120 75D cationic composite yarn. In summary, the curtain fabric 100 according to this embodiment of the present invention utilizes novel low-melting-point fibers to melt and then solidify the original warp and weft yarns after weaving, thus forming a light-blocking film within the fabric.

[0067] Weaving: Double warp and single weft structure, warp density 150 threads / cm, weft density 25 threads / cm; Heat setting: 185℃×90s treatment to completely melt the yarn sheath 32.

[0068] According to one embodiment of the present invention, the curtain fabric 100, when applied to curtains, can be a double-warp, single-weft black silk blackout curtain, suitable for bedroom use. Specifically, the fabric structure is as follows: Outer layer 110 (decorative layer): 75D polyester matte yarn, using a double-warp, single-weft structure, with a 1.8x pleat design to enhance drape. Middle layer 130: Middle layer 130 uses 300D core 31 yarn (core: regular polyester; sheath: low melting point polyester 120 degrees). Bottom layer 120: 75D cationic composite yarn. It adopts a five-end, three-fly weave specification, with a warp density of 120 threads / cm and a weft density of 25 threads / cm.

[0069] In related technologies, black and gold-backed curtains manufactured by physical weaving have a light-blocking effect of over 95%, a weight of 400gsm, and a light-blocking effect that decreases to about 90% after 50 washes; the blackout curtains of this application have a light-blocking effect of over 99%, a weight of 350gsm, and a light-blocking effect of about 99% after 50 washes.

[0070] In some embodiments of this utility model, the curtain fabric as described above can be made according to the following steps, including: first step, pre-weaving treatment; second step, weaving; third step, dyeing and finishing, including pre-dyeing treatment → dyeing and heating and melting → finishing → rolling.

[0071] Specifically, the manufacturing process consists of the following steps: pre-weaving treatment → weaving → pre-dyeing treatment → dyeing (heating and melting) → finishing → rolling → finished product processing.

[0072] More specifically, the pre-weaving treatment can involve arranging the first thread 10, the second thread 20, and the third thread 30 in parallel and evenly, or performing special treatments on threads of special materials, to improve the finished product. Weaving: This involves cross-weaving the first thread 10 and the second thread 20, and wrapping the third thread 30 between the first thread 10 and the second thread 20. Specifically, the threads treated in the first step can be interwoven on a loom to form a grey fabric. Further, the grey fabric formed in the second step undergoes pre-treatment, i.e., pre-dyeing treatment, to remove impurities and improve its dyeing performance.

[0073] Furthermore, the treated fabric is dyed and heated to melt. The dyeing and finishing process includes dyeing the first thread 10, the second thread 20, and the third thread 30 after weaving and then heating and melting them at a preset temperature. The core 31 of the third thread 30 acts as a support within the sheath 32. The sheath 32 can be fused together during processing, allowing multiple sheaths 32 of the third thread 30 to connect and form a surface. After curing, multiple third threads 30 together form a film-like or layered structure between the first thread 10 and the second thread 20. The dyed and heated fabric undergoes functional and aesthetic finishing. Finally, the finished fabric is rolled into a roll, and then cut and sewn to produce the finished curtain fabric.
