Abstract
Description
Technical Field
[0001] This application relates to the field of automotive pop-top tent technology, and more particularly to a composite fabric processing technology and composite fabric structure for composite fabric structures. Background Technology
[0002] Currently, as disclosed in the application document CN201710611432.X, a folding tarpaulin for a vehicle roof lifting system is used. This solution commonly uses material splicing and sewing to achieve a large area of tarpaulin, which is a conventional method for traditional pop-up tents. However, this practice of using "large-area synchronous sewing" to sew the outer, middle, inner, and internal functional components into one piece at once will result in needle holes penetrating the entire fabric thickness, forming water seepage channels and posing a risk of water leakage when used outdoors. In addition, on the one hand, the large number of exposed seams makes the overall appearance quality of the pop-up tent poor. On the other hand, the tarpaulin is formed by mechanical stress generated by the pulling of the sewing machine needle, which will cause irreversible wavy wrinkles on the surface of the entire tarpaulin. Summary of the Invention
[0003] This application provides a composite fabric processing technology and a composite fabric structure for use in composite fabric structures, which can improve waterproof performance.
[0004] To achieve the above objectives, the main technical solutions adopted in this application include: Firstly, the processing technology for composite fabrics includes the following steps: Step 1: Sew the V-shaped guide plate to the middle support fabric; Step 2: Secure the outer and inner fabrics to both sides of the middle support fabric using PUR adhesive. Step 3: The outer fabric, middle support fabric and inner fabric are heat-pressed together in a flat state using hot press rollers to form a composite fabric structure, and all seams are completely hidden inside the interlayer of the composite fabric structure. Step 4: Fix the shaped steel pipe onto the composite fabric structure.
[0005] This application proposes a composite fabric processing technology for composite fabric structures. A V-shaped guide plate is sewn and fixed to the middle support fabric. Then, the outer and inner fabrics are fixed to both sides of the middle support fabric with PUR adhesive. With the help of hot pressing rollers, the three are hot-pressed together in a flat state, so that all the seams are completely hidden inside the interlayer of the composite fabric structure, replacing the traditional large-area through-sewing. There are no through-holes for fixing on the outer and inner fabrics, eliminating the channels for rainwater to seep in along the needle holes and improving the waterproof effect.
[0006] Understandably, since the V-shaped guide plate is pre-sewn and fixed to the middle support fabric, its seams are completely wrapped inside the interlayer between the middle layer, outer layer, and inner layer after the subsequent PUR glue hot-pressing composite, so that there are no exposed seams in the main area of the composite fabric structure, eliminating the visual defects caused by traditional large-area sewing and significantly improving the appearance of the pop-up tent.
[0007] Optionally, between step 3 and step 4, step 3.1 is further included: making a hole on the outer surface of the composite fabric structure; wherein, in step 4, a shaped steel pipe is inserted into the interior of the composite fabric structure through the hole and the shaped steel pipe is fixed on the middle support fabric.
[0008] Optionally, in step 1, the shaping bag is simultaneously sewn and fixed onto the middle support fabric, and the shaping bag has a through hole; in step 3.1, a hole is made at the inner fabric at the position corresponding to the end of the through hole, and the shaping steel pipe is passed through the through hole to sew and fix the shaping steel pipe onto the composite fabric structure.
[0009] Optionally, between step 1 and step 2, step 1.1 is further included: pre-positioning an identifier at the end of the through hole in the shaping bag; after step 4, step 5 is further included: stitching the opening in step 3.1.
[0010] Optionally, the marker is a snap fastener and / or button sewn onto the shaping bag; wherein, in step 4, the position of the marker is confirmed by touching with a finger or observing with the naked eye the raised bumps formed on the surface of the outer fabric due to the marker.
[0011] Optionally, the marker is a metal sheet sewn onto the shaping bag; wherein, in step 4, a magnetic pen or metal detector is used to scan the outer surface of the composite fabric structure, and the position of the marker is confirmed by capturing the magnetic attraction or metal signal generated by the metal sheet.
[0012] Optionally, step 5 may also include removing the metal sheet.
[0013] Optionally, in step 3.1, only the inner fabric is perforated, and in step 5, the hook stitching is performed by: artistic hook stitching of the opening edge of the inner fabric and the middle support fabric to make the surface of the outer fabric intact.
[0014] Secondly, embodiments of this application provide a composite fabric structure, manufactured using the composite fabric processing technology of the first aspect, comprising a middle supporting fabric, V-shaped guide plates, a shaping steel pipe, an inner fabric, and an outer fabric. Multiple V-shaped guide plates are provided, arranged along the folding direction of the middle supporting fabric. The V-shaped guide plates are fixed to the middle supporting fabric and are used to guide the middle supporting fabric in an accordion-like fold. The shaping steel pipe is fixed between two adjacent V-shaped guide plates and is arranged along the length direction of the middle supporting fabric. The inner fabric is fixedly connected to the middle supporting fabric and covers the V-shaped guide plates and the shaping steel pipe. The outer fabric is fixedly connected to the middle supporting fabric.
[0015] Optionally, the composite fabric structure further includes a shaping bag, which is fixed between two adjacent V-shaped guide plates. The shaping bag is provided with a through hole for inserting a shaping steel tube, and the through hole is provided along the length direction of the middle layer support fabric.
[0016] Optionally, the inner layer fabric has openings, the openings correspond to the positions of the through holes, and the edges of the openings are fixedly connected only to the middle layer support fabric.
[0017] Optionally, the thickness of the middle support fabric is greater than the thickness of the V-shaped guide plate, the thickness of the shaping bag, and the diameter of the shaping steel tube, so that the V-shaped guide plate, the shaping bag, and the shaping steel tube are embedded in the middle support fabric.
[0018] Optionally, the outer layer fabric is made of waterproof fabric, the middle support fabric is made of thermal insulation fabric, and the inner layer fabric is velvet fabric.
[0019] The composite fabric structure proposed in this application improves the waterproof effect to at least a certain extent. Attached Figure Description

[0028] Reference Figure 1 The composite fabric processing technology of this invention includes the following steps: Step 1: Sew the V-shaped guide plate 200 to the middle support fabric 100; Step 2: Fix the outer fabric 500 and the inner fabric 400 to both sides of the middle support fabric 100 using PUR adhesive; Step 3: The outer fabric 500, the middle support fabric 100 and the inner fabric 400 are heat-pressed together in a flat state using hot press rollers to form a composite fabric structure, and all seams are completely hidden inside the interlayer of the composite fabric structure. Step 4: Fix the 600-shaped steel pipe onto the composite fabric structure.
[0029] The aforementioned composite fabric structure includes a middle support fabric 100, V-shaped guide plates 200, a shaped steel pipe 600, an inner fabric 400, and an outer fabric 500. Multiple V-shaped guide plates 200 are arranged along the folding direction of the middle support fabric 100 and are fixed to it. The V-shaped guide plates 200 guide the middle support fabric 100 in an accordion-like fold. The shaped steel pipe 600 is fixed between adjacent V-shaped guide plates 200 and is arranged along the length of the middle support fabric 100. The inner fabric 400 is fixedly connected to the middle support fabric 100 and covers the V-shaped guide plates 200 and the shaped steel pipe 600. The outer fabric 500 is fixedly connected to the middle support fabric 100.
[0030] In the composite fabric processing of this embodiment, the V-shaped guide plate 200 is first sewn and fixed onto the middle support fabric 100, with the seams exposed on the surface of the middle support fabric 100. Then, PUR adhesive is applied to both sides of the middle support fabric 100, and the outer fabric 500 and inner fabric 400 are respectively attached to both sides of the middle support fabric 100. Next, the three layers of fabric are fed into a hot-pressing roller device, and hot-pressing is performed while the fabric remains unfolded and flat, bonding the three layers together. During the hot-pressing process, the seams of the V-shaped guide plate 200, which were originally exposed on the surface of the middle support fabric 100, are completely encased within the interlayer between the outer fabric 500 and the middle support fabric 100, making them invisible from the outside. Finally, the shaping steel pipe 600 is fixed to the composite fabric structure, completing the preparation of the composite fabric structure assembly.
[0031] Specifically, during use, when the pop-up tent is unfolded, the V-shaped guide plate 200 guides the entire composite fabric structure to unfold in an accordion-like manner along a preset direction, and the shaped steel pipe 600 provides lateral support for the composite fabric structure, so that the composite fabric structure maintains a crisp and flat unfolded shape; when the pop-up tent is retracted, the V-shaped guide plate 200 guides the composite fabric structure to fold in an orderly manner along the folding direction, avoiding disorderly stacking of the fabric.
[0032] In summary, in the composite fabric processing technology and specific composite fabric structure of this embodiment, the V-shaped guide plate 200 is sewn and fixed to the middle support fabric 100. Then, the outer fabric 500 and the inner fabric 400 are fixed to both sides of the middle support fabric 100 with PUR adhesive. With the help of hot pressing rollers, the three are hot-pressed together in a flat state, so that all the seams are completely hidden inside the interlayer of the composite fabric structure, replacing the traditional large-area through-seam stitching. There are no through needle holes for fixing on the outer fabric 500 and the inner fabric 400, eliminating the channel for rainwater to seep in along the needle holes and improving the waterproof effect.
[0033] Understandably, since the V-shaped guide plate 200 is pre-sewn and fixed to the middle support fabric 100, its seams are completely wrapped inside the interlayer between the middle layer, outer layer and inner layer after subsequent PUR glue hot pressing and lamination. This results in no exposed seams in the main area of the composite fabric structure, eliminating the visual defects caused by traditional large-area sewing and significantly improving the appearance of the pop-up tent.
[0034] In some embodiments, between step 3 and step 4, step 3.1 is further included: making a hole on the outer surface of the composite fabric structure; wherein, in step 4, the shaping steel tube 600 is inserted into the interior of the composite fabric structure through the hole and the shaping steel tube 600 is fixed on the middle support fabric 100.
[0035] After completing the hot-pressing composite in step 3, the outer fabric 500, the middle support fabric 100, and the inner fabric 400 are firmly bonded together with PUR adhesive, and all seams are hidden inside the interlayer. At this point, a hole is made at the predetermined position of the composite fabric structure (i.e., the installation position of the shaped steel pipe 600) to form a channel for the shaped steel pipe 600 to pass through. Subsequently, the shaped steel pipe 600 is inserted into the interior of the composite fabric structure through the hole, so that the steel pipe extends in the predetermined direction to the corresponding area of the composite fabric structure. Finally, the shaped steel pipe 600 is fixed to the middle support fabric 100, completing the installation of the shaped steel pipe 600.
[0036] To better facilitate the installation of the aforementioned shaped steel tube 600, in some embodiments, the composite fabric structure also includes a shaped bag 300. The shaped bag 300 is fixed between two adjacent V-shaped guide plates 200. The shaped bag 300 has a through hole 310 for inserting the shaped steel tube 600, and the through hole 310 is arranged along the length direction of the middle supporting fabric 100. The shaped bag 300 is sewn to the middle supporting fabric 100, and its internal through hole 310 provides a guide channel for the shaped steel tube 600. After the shaped steel tube 600 is inserted, it and the V-shaped guide plate 200 together form the "skeleton" of the composite fabric structure: the V-shaped guide plate 200 guides the accordion-style folding direction, and the shaped steel tube 600 maintains the stability of the overall structure.
[0037] Understandably, as a process optimization of the above structure, in step 1, the shaping bag 300 is simultaneously sewn and fixed to the middle support fabric 100, and the shaping bag 300 is provided with a through hole 310; in step 3.1, a hole is made at the inner fabric 400 at the corresponding position at the end of the through hole 310, and the shaping steel tube 600 is passed through the through hole 310 to sew and fix the shaping steel tube 600 to the composite fabric structure.
[0038] It should be mentioned that, in the above embodiments, although the PUR adhesive hot-press lamination can achieve seam concealment and waterproof sealing, it also completely encases all internal structures—including the end position of the through hole 310 of the shaping bag 300—within the fabric interlayer, making it impossible to determine the opening position by visual inspection from the outside. To further improve the efficiency of installing the shaping steel tube 600, a step 1.1 is included between steps 1 and 2: pre-positioning a marker at the end of the through hole 310 in the shaping bag 300; after step 4, a step 5 is included: stitching the opening in step 3.1. By pre-positioning the marker before lamination, and utilizing the marker's ability to provide detectable positioning signals (such as physical protrusions, magnetic signals, etc.) after lamination, a process path of "sealing first, positioning later, and then opening" is achieved, balancing sealing and ease of operation.
[0039] Furthermore, in step 5, only the inner fabric 400 is perforated, and the hook-stitching in step 5 involves artistic hook-stitching of the opening edge of the inner fabric 400 and the middle support fabric 100 to ensure the outer fabric 500 surface remains intact. During the perforation step, the operator performs the perforation from the inside of the composite fabric structure (i.e., the inner fabric 400 side), penetrating only the inner fabric 400 without penetrating the middle support fabric 100 or the outer fabric 500. After perforation, the end of the through-hole 310 of the shaping bag 300 is exposed from the opening of the inner fabric 400. After the tube is inserted, the opening edge of the inner fabric 400 is stitched using artistic hook-stitching, connecting only the opening edge of the inner fabric 400 to the surface of the middle support fabric 100 without penetrating the outer fabric 500. After sewing, viewed from the outside of the composite fabric structure, the outer fabric 500 remains intact and free of needle holes at the corresponding positions; viewed from the inside of the composite fabric structure, the opening edges are covered with exquisite stitching, presenting an artistic decorative effect. On the other hand, sewing on the inside ensures the waterproof effect on the outside.
[0040] In this embodiment, the inner fabric 400 has openings that correspond to the positions of the through holes 310, and the edges of the openings are fixedly connected only to the middle support fabric 100. This ensures that the opening positions allow the shaped steel pipe 600 to be inserted.
[0041] As one specific embodiment of the above, the marker is a snap fastener and / or button sewn onto the shaping bag 300; wherein, in step 4, the position of the marker is confirmed by touching it with a finger or by visually observing the raised bumps formed on the surface of the outer fabric 500 due to the marker.
[0042] In another specific embodiment described above, the marker is a metal sheet sewn onto the shaping bag 300; wherein, in step 4, a magnetic pen or metal detector is used to scan the outer surface of the composite fabric structure, and the position of the marker is confirmed by capturing the magnetic attraction or metal signal generated by the metal sheet. In this embodiment, step 5 further includes removing the metal sheet.
[0043] In some embodiments, the thickness of the middle support fabric 100 is greater than the thickness of the V-shaped guide plate 200, the thickness of the shaping bag 300, and the diameter of the shaping steel tube 600, so that the V-shaped guide plate 200, the shaping bag 300, and the shaping steel tube 600 are embedded within the middle support fabric 100. The thickness of the middle support fabric 100 is sufficient to completely accommodate the V-shaped guide plate 200 and the shaping steel tube 600. During the hot-pressing process, the pressure of the hot-pressing rollers causes the middle support fabric 100 to be locally compressed and wraps around the V-shaped guide plate 200 and the shaping steel tube 600. After the composite is completed, the outer fabric 500 remains smooth and flat without any protrusions. Specifically, referring to the following specific embodiment, the thickness of the middle support fabric 100 is 6mm, and on the middle support fabric 100, there is a V-shaped guide plate 200 with a thickness of 1mm and a shaping steel tube 600 with a diameter of 3mm. By setting the thickness of the middle support fabric 100 to 6mm, the thickness of the V-shaped guide plate 200 to 1mm, and the diameter of the shaping steel tube 600 to 3mm, the V-shaped guide plate 200, the shaping bag 300, and the shaping steel tube 600 can be embedded within the middle support fabric 100. It is understood that the diameters of the V-shaped guide plate 200, the shaping steel tube 600, and the thickness of the shaping bag 300 can be any combination of these parameters.
[0044] In some embodiments, the outer fabric 500 is made of waterproof fabric, the middle support fabric 100 is made of thermal insulation fabric, and the inner fabric 400 is made of velvet fabric.
[0045] In summary, referring to the above, Figure 4 The composite fabric processing technology of this invention includes the following steps: Step 1: Sew the V-shaped guide plate 200 and the shaping bag 300 onto the middle support fabric 100; Step 1.1: Pre-place a marker at the end of the through hole 310 in the shaping bag 300; Step 2: Fix the outer fabric 500 and the inner fabric 400 to both sides of the middle support fabric 100 using PUR adhesive; Step 3: The outer fabric 500, the middle support fabric 100 and the inner fabric 400 are heat-pressed together in a flat state using hot press rollers to form a composite fabric structure, and all seams are completely hidden inside the interlayer of the composite fabric structure. Step 3.1: Make a hole on the outer surface of the composite fabric structure. The hole is located at the inner fabric 400 at the end of the through hole 310. Step 4: Insert the shaping steel tube 600 into the end of the through hole 310 of the shaping bag 300 and fix the shaping steel tube 600 to the composite fabric structure.
[0046] Step 5: Sew the openings from Step 3.1 with hook stitches so that the middle support fabric 100 is sewn only to the inner fabric 400.
