Description

Technical Field

[0001] The present invention relates to a textile suture structure, and in particular to a high-strength textile suture structure and a manufacturing method thereof. Prior Art

[0002] Products for outdoor sports applications such as anti-fall clothing, protective gear, and backpacks, military protection applications such as bulletproof vests and puncture-resistant clothing, and automotive interior applications such as seats and seat belts are often made of high-strength textile fabrics because they require excellent tensile, tear, and abrasion resistance, thereby significantly improving product safety and durability.

[0003] However, during the sewing process, the above-mentioned products often suffer from problems such as thread damage and uneven thread tension caused by the needle and thread penetrating the fabric, resulting in reduced strength at the seams, and further causing thread breakage, wear, or fabric tearing. In addition, due to the special usage of high-strength textile fabrics, their seams often become the weak link of the product. Traditional sewing technology cannot effectively deal with the stress problems caused by stretching and wear at the seams, which often leads to seam breakage and rupture at the seams, thereby shortening the product life and even endangering the safety of users.

[0004] In view of this, the present inventor has devoted himself to studying the above-mentioned prior art and has applied theoretical knowledge to try his best to solve the above-mentioned problems, which has become the goal of the present inventor's development. Summary of the Invention

[0005] The present invention provides a high-strength textile seam structure and a method for manufacturing the same. The structure utilizes a reinforcing fabric sheet, a first seam thread, and a second seam thread to reinforce the seams of a main fabric, thereby achieving high tensile strength and tear resistance in the high-strength textile seam structure.

[0006] In an embodiment of the present invention, a high-strength textile sewing structure is provided, comprising: a pair of main fabrics, comprising: two first flat sections spaced apart and arranged side by side, two first inverted sections folded downward from adjacent sides of the two first flat sections, and two extension sections extending from the ends of the two first inverted sections and disposed below the two first flat sections, with a seam formed between the two first inverted sections; a reinforcing fabric sheet, comprising: a second flat section stacked above the two first flat sections, two second inverted sections folded downward from both outer sides of the second flat section and disposed through the seam, and a remaining section stacked below the two extension sections; a first stitching line stitching the two first inverted sections to the two second inverted sections; and a pair of second stitching lines stitching the left and right sides of the second flat section to the first flat sections, and to the remaining sections to the extension sections.

[0007] In an embodiment of the present invention, a method for manufacturing a high-strength textile seam structure is provided, comprising the following steps: A) providing a pair of main fabrics, a reinforcing fabric sheet, and a first stitching line; folding the pair of main fabrics into two first flat sections spaced apart and arranged side by side, two first inverted sections folded downward from adjacent sides of the two first flat sections, and two extension sections extending from ends of the two first inverted sections and disposed below the two first flat sections, with a seam formed between the two first inverted sections; folding the reinforcing fabric sheet into a second flat section stacked above the two first flat sections, two second inverted sections folded downward from both outer sides of the second flat section and disposed through the seam, and a remaining section stacked below the two extension sections; and sewing the two first inverted sections to the two second inverted sections via the first stitching line; and B) providing a pair of second stitching lines, and sewing the left and right sides of the second flat section to the first flat sections, and to the extension sections to the remaining section via the pair of second stitching lines.

[0008] Based on the above, a reinforcing fabric piece is inserted through the seam of the main fabric, and then the first inverted section of the main fabric aligned with the seam is sewn together with the second inverted section of the reinforcing fabric piece using a first stitch. Finally, the left and right sides of the second flat section of the main fabric covering the seam are sewn together with the first flat sections, the extended sections of the reinforcing fabric piece, and the remaining sections using a second stitch. This ensures that the seam of the main fabric is reinforced by the reinforcing fabric piece, the first stitch, and the second stitch. This prevents problems such as seam breakage, fabric slippage, cracking, or rupture at the seam of the main fabric, thereby ensuring that the high-strength textile seam structure of the present invention has high tensile strength and tear resistance.

[0009] Based on the above, the reinforcing fabric piece can be an inverted U-shaped fabric piece or an O-shaped fabric piece. When the reinforcing fabric piece is an inverted U-shaped fabric piece, the inverted U-shaped fabric piece will be bonded with the adhesive tape to increase the structural strength. The adhesive tape can improve the friction resistance of the reinforcing fabric piece, and thus it is suitable for application to areas of clothing with less wear, such as shoulders, back, legs and chest, so that the high-strength textile sewing structure has stronger adaptability and wear resistance; when the reinforcing fabric piece is an O-shaped fabric piece, the O-shaped fabric piece can provide all-round uniform support and reinforcement effects due to its own shape, and is suitable for application to key parts of clothing, such as shoulders, back and legs, thereby enhancing the overall durability and safety of the high-strength textile sewing structure of the present invention.

[0026] The detailed description and technical contents of the present invention will be described below with reference to the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the present invention.

[0027] 1 to 6 , the present invention provides a first embodiment of a high-strength textile stitching structure and a method for manufacturing the same. The high-strength textile stitching structure 10 primarily includes a pair of main fabrics 1, a reinforcing fabric sheet 2, a first stitching thread 3, an adhesive tape 6, and a pair of second stitching threads 4.

[0028] As shown in FIG1 and FIG2, the steps of the method for making the first embodiment of the high-strength textile stitching structure 10 of the present invention are as follows: first, as shown in step S11 of FIG1 and FIG3, a pair of main fabrics 1, a reinforcing fabric sheet 2, and a first stitching line 3 are provided. The main fabrics 1 are folded into two first flat sections 11 spaced apart and arranged in parallel, two first inverted sections 12 folded downward from adjacent sides of the two first flat sections 11, and two extending sections 13 extending from the ends of the two first inverted sections 12 and disposed below the two first flat sections 11. A seam S is formed between the two first inverted sections 12. The reinforcing fabric sheet 3 is then folded into the reinforcing fabric sheet 2. 2 is folded to form a second flat section 21 stacked on top of the two first flat sections 11 and covering the seam S, two second inverted sections 22 folded downward from the two outer sides of the second flat section 21 and inserted into the seam S, and a remaining section 23 stacked below the two extended sections 13. The two first inverted sections 12 and the two second inverted sections 22 are sewn together using the first stitching 3. That is, the two first inverted sections 12 and the two second inverted sections 22 are sewn together using the first stitching 3. The second flat section 21 is a flat Ω-shaped section 51, and the remaining section 23 is two straight-line sections 52 stacked below each extended section 13.

[0029] The main fabric 1 can be a high-strength fabric, but is not limited thereto. The high-strength fabric is made of at least one of high-strength wear-resistant nylon fiber (such as CORDURA®), high-strength polyester fiber (PET), aromatic polyamide fiber (such as Kevlar®), ultra-high molecular weight polyethylene fiber (UHMWPE), liquid crystal polymer fiber (Vectran®), and carbon fiber.

[0030] Furthermore, a preferred embodiment of the main fabric 1 is made of a plain woven fabric composed of 84.2% nylon fiber, 6.8% liquid crystal polymer fiber, and 9% polyurethane coating. The plain woven fabric has a warp density of 69 yarns per inch and a weft density of 47 yarns per inch, with each weft inch containing 8 liquid crystal polymer fiber yarns. The plain woven fabric weighs 215 g / m² and has a thickness of 0.55 mm. This gives the main fabric 1 excellent strength and durability, meeting the high-strength requirements of outdoor sports applications such as anti-fall clothing, protective gear, and backpacks, military protective applications such as bulletproof vests and puncture-resistant clothing, and automotive interior applications such as seats and seat belts.

[0031] The reinforcing fabric sheet 2 is made of high-strength synthetic fibers, such as nylon, polyester, or high-performance fibers with special functions. Preferably, the reinforcing fabric sheet 2 is made of nylon plain weave fabric with a warp density of 112 threads per inch, a weft density of 94 threads per inch, a fabric weight of 272 g / m², and a thickness of 0.53 mm. This allows the reinforcing fabric sheet 2 to provide stable and durable structural support for the seam area.

[0032] As further described below, as shown in FIG. 2 , step S11 sequentially includes steps S21, S22, and S23. First, in step S21, the reinforcing fabric sheet 2 of this embodiment is formed by an inverted U-shaped fabric sheet 5 disposed transversely between the upper and lower stacked main fabric sheets 1. Furthermore, in step S22, the inverted U-shaped fabric sheet 5 is sewn to the main fabric sheets 1 using a first stitch 3. Finally, in step S23, two first flat sections 11, two first inverted sections 12, and two extended sections 13 are folded from the main fabric sheets 1 so that the inverted U-shaped fabric sheet 5 is inserted into the seam S. The top of the inverted U-shaped fabric sheet 5 is then flattened into a flat Ω-shaped section 51, and two straight-line sections 52 are folded from the bottom ends of the inverted U-shaped fabric sheet.

[0033] Second, as shown in step S12 of FIG. 1 and FIG. 4 , an adhesive tape 6 is provided and adhered below the U-shaped segment 52 to cover the seam S. The adhesive tape 6 can be a hot-melt adhesive tape or a cold-press adhesive tape. Hot-melt adhesive tapes can be melt-bonded at high temperatures, while cold-press adhesive tapes can be cold-bonded at room temperature. This improves the bond strength with the reinforcing fabric 2 and ensures that the seams do not debond or peel during use. The adhesive tape 6 can be a single-sided cloth tape or a plastic film tape, making it suitable for high-strength fabrics and exhibiting excellent abrasion resistance, tensile strength, and thermal stability.

[0034] Furthermore, the adhesive tape 6 is preferably made of a 0.4 mm thick fabric-covered TPU hot-melt tape, and is heat-pressed at a temperature of 150°C and a pressure of 5 kg / cm² for 20 seconds to ensure a firm bond between the fabric-covered TPU hot-melt tape and the reinforcing fabric sheet 2, further enhancing the strength and durability of the seam.

[0035] Third, as shown in step S13 of FIG. 1 and FIG. 5 to FIG. 6 , a pair of second stitches 4 is provided, and the left and right sides of the second flat section 21 are sewn together with the first flat sections 11, the extension sections 13, and the remaining sections 23, respectively, through the pair of second stitches 4. That is, the left and right sides of the adhesive tape 6 and the left and right sides of the flat Ω-shaped section 51 are sewn together with the first flat sections 11, the extension sections 13, and the straight-line sections 52, respectively, through the pair of second stitches 4.

[0036] Furthermore, the adhesive tape 6 is primarily used to increase the structural strength of the inverted U-shaped fabric piece 5 and is not an essential component of the high-strength textile stitching structure 10 of the present invention. The adhesive tape 6 may be omitted depending on the actual situation. In other words, the adhesive tape 6 may not be applied below the two I-shaped segments 52, and only the left and right sides of the flat Ω-shaped segment 51 may be sewn together with the first flattened segments 11, the extension segments 13, and the I-shaped segments 52, respectively, via the pair of second stitches 4.

[0037] As shown in Figures 5 and 6, the first embodiment of the high-strength textile sewing structure 10 of the present invention is in use. The structure utilizes a reinforcing fabric sheet 2 inserted through a seam S of a main fabric sheet 1. A first stitch 3 is then used to sew the first inverted section 12 of the main fabric sheet 1 aligned at the seam S to the second inverted section 22 of the reinforcing fabric sheet 2. Furthermore, because the reinforcing fabric sheet 2 of this embodiment is an inverted U-shaped sheet 5, the inverted U-shaped sheet 5 can be bonded to an adhesive tape 6 to increase structural strength. However, the adhesive tape 6 is optional and can be omitted. Finally, a second stitch 4 is used to sew the left and right sides of the second flat section 21 of the main fabric sheet 1 covering the seam S to the first flat sections 11, the extended sections 13 and the remaining section 23 of the reinforcing fabric sheet 2, and the adhesive tape 6, respectively. In this way, the seams of the main fabric 1 are reinforced by the reinforcing fabric piece 2, the first seam 3, and the second seam 4, thereby preventing the seams of the main fabric 1 from breaking, slipping, cracking, or rupture, thereby achieving high tensile strength and tear resistance of the high-strength textile seam structure 10 of the present invention.

[0038] In addition, the reinforcing fabric piece 2 of this embodiment is an inverted U-shaped fabric piece 5, and the inverted U-shaped fabric piece 5 is bonded with an adhesive tape 6 to increase structural strength. The adhesive tape 6 can improve the friction resistance of the reinforcing fabric piece 2, making it suitable for use in areas of clothing that are less prone to wear, such as the shoulders, back, legs, and chest. This allows the high-strength textile seam structure 10 to have greater adaptability and wear resistance.

[0039] As shown in Figures 7 and 8, this is a second embodiment of the high-strength textile suture structure 10 of the present invention. The embodiment of Figures 7 and 8 is roughly the same as the embodiment of Figures 1 to 6. The difference between the embodiment of Figures 7 and 8 and the embodiment of Figures 1 to 6 is that the high-strength textile suture structure 10 further includes a strip 8.

[0040] The strip 8 is described in detail below. The strip 8 is inserted into the flat Ω-shaped segment 51. The strip 8 is a rope 81 or a belt, but is not limited thereto. The rope 81 or belt is made of high-strength fibers such as polyester, nylon, aromatic polyamide (Kevlar®), or ultra-high molecular weight polyethylene (UHMWPE). The rope 81 or belt provides excellent tensile strength and durability at the flat Ω-shaped segment 51, thereby further enhancing the tensile strength and structural strength of the high-strength textile suture structure 10 of the present invention.

[0041] As shown in Figure 9, this is the third embodiment of the high-strength textile suture structure 10 of the present invention. The embodiment of Figure 9 is roughly the same as the embodiments of Figures 7 to 8. The difference between the embodiment of Figure 9 and the embodiments of Figures 7 to 8 is that the strip member 8 is a strip sheet 82 or a strip rod.

[0042] As further explained below, the strip sheet 82 or the strip rod is made of metal, polyester (PET), nylon (Nylon), polyurethane (TPU), or polyethylene (PE). Furthermore, the strip sheet 82 or the strip rod provides excellent tensile strength and durability at the flat Ω-shaped section 51, thereby further enhancing the tensile strength and structural strength of the high-strength textile suture structure 10 of the present invention.

[0043] In addition, the strip sheets 82 or strip rods made of polyester (PET), nylon (Nylon), polyurethane (TPU) or polyethylene (PE) are lighter and more flexible than the strip sheets 82 or strip rods made of metal. Therefore, if the high-strength textile suture structure 10 of the present invention has a higher rigidity requirement for the sutures, the strip sheets 82 or strip rods made of metal are selected for use. If the high-strength textile suture structure 10 of the present invention has a higher lightweight requirement for the sutures, the strip sheets 82 or strip rods made of polyester (PET), nylon (Nylon), polyurethane (TPU) or polyethylene (PE) are selected for use.

[0044] 7 to 8, the strip member 8 is a rope 81, a belt or a strip rod that can be used to centrally enhance the linear strength of the suture, and the strip member 8 is a strip sheet 82 that can be used for large-area suture areas that require dispersed force.

[0045] Please refer to Figures 10 to 14, which are the fourth embodiment of the high-strength textile suture structure 10 of the present invention. The embodiments of Figures 10 to 14 are roughly the same as the embodiments of Figures 1 to 6. The difference between the embodiments of Figures 10 to 14 and the embodiments of Figures 1 to 6 lies in the different steps of the manufacturing method.

[0046] As shown in Figures 10 and 11, the steps of the manufacturing method of the fourth embodiment of the high-strength textile stitching structure 10 of the present invention are as follows: first, as shown in step S31 of Figure 10 and Figure 12, the main fabric 1, the reinforcing fabric 2 and the first stitching line 3 are provided, the main fabric 1 is folded into two first flat sections 11 spaced apart and parallel, two first reversed sections 12 reversed downwardly from adjacent sides of the two first flat sections 11, and two extension sections 13 extending from the ends of the two first reversed sections 12 and arranged below the two first flat sections 11, a connecting section 13 is formed between the two first reversed sections 12. The reinforcing fabric sheet 2 is folded to form a second flat section 21 stacked on top of the two first flat sections 11 and covering the seam S, two second inverted sections 22 folded downward from the outer sides of the second flat section 21 and passing through the seam S, and a remaining section 23 stacked below the two extended sections 13. The two first inverted sections 12 and the two second inverted sections 22 are sewn together using the first stitching 3. That is, the two first inverted sections 12 and the two second inverted sections 22 are sewn together using the first stitching 3. The second flat section 21 is a flat Ω-shaped section 71, and the remaining section 23 is a flat inverted Ω-shaped section 72.

[0047] The details are as follows. As shown in FIG. 11 , step S31 sequentially includes steps S41, S42, and S43. First, in step S41, the reinforcing fabric sheet 2 of this embodiment is formed by an O-shaped fabric sheet 7 disposed transversely between the upper and lower stacked main fabric sheets 1. Furthermore, in step S42, the O-shaped fabric sheet 7 is sewn to the main fabric sheets 1 using a first stitching thread 3. Finally, in step S43, two first flat sections 11, two first inverted sections 12, and two extended sections 13 are folded from the main fabric sheets 1 so that the O-shaped fabric sheet 7 is inserted into the seam S. The top end of the O-shaped fabric sheet 7 is then flattened into a flat Ω-shaped section 71, and the bottom end of the O-shaped fabric sheet 7 is flattened into a flat inverted Ω-shaped section 72.

[0048] Second, as shown in step S31 of Figure 10 and Figures 13 to 14, a pair of second sutures 4 are provided, and the left and right sides of the second flat segment 21 are respectively sewn together with the first flat segments 11, the extension segments 13 and the remaining segments 23 through the pair of second sutures 4, that is, the left and right sides of the flat inverted Ω-shaped segment 72 and the left and right sides of the flat Ω-shaped segment 71 are respectively sewn together with the first flat segments 11 and the extension segments 13 through the pair of second sutures 4.

[0049] Figures 13 and 14 illustrate the fourth embodiment of the high-strength textile seam structure 10 of the present invention in use. The structure employs a reinforcing fabric sheet 2 inserted through a seam S of a main fabric 1. A first stitch 3 is then used to sew the first inverted section 12 of the main fabric 1 aligned with the seam S to the second inverted section 22 of the reinforcing fabric sheet 2. Finally, a second stitch 4 is used to sew the left and right sides of the second flat section 21 of the main fabric 1 covering the seam S to the first flat sections 11, the extended sections 13 of the reinforcing fabric sheet 2, and the remaining section 23, respectively. In this manner, the seam of the main fabric 1 is reinforced by the reinforcing fabric sheet 2, the first stitch 3, and the second stitch 4, thereby preventing problems such as seam breakage, fabric slippage, cracking, or rupture at the seam of the main fabric 1. This ensures that the high-strength textile seam structure 10 of the present invention exhibits high tensile strength and tear resistance.

[0050] In addition, the reinforcing fabric piece 2 of this embodiment is an O-shaped fabric piece 7. Due to its shape, the O-shaped fabric piece 7 can provide all-round uniform support and reinforcement effects, and is suitable for application to key parts of clothing, such as shoulders, back, and legs, thereby enhancing the overall durability and safety of the high-strength textile seam structure 10 of the present invention.

[0051] As shown in Figure 15, it is the fifth embodiment of the high-strength textile sewing structure 10 of the present invention. The embodiment of Figure 15 is roughly the same as the embodiments of Figures 10 to 14. The difference between the embodiment of Figure 15 and the embodiments of Figures 10 to 14 is that the high-strength textile sewing structure 10 further includes one or more strips 8.

[0052] Further explanation is as follows, the strip member 8 can be inserted into at least one of the flat Ω-shaped segment 71 and the flat inverted Ω-shaped segment 72, that is, two strip members 8 are inserted into the flat Ω-shaped segment 71 and the flat inverted Ω-shaped segment 72 respectively, or one strip member 8 is inserted into the flat Ω-shaped segment 71 or the flat inverted Ω-shaped segment 72. The strip member 8 is a rope body 81 or a belt body, but is not limited to this. The rope body 81 or the belt body is made of high-strength fiber such as polyester, nylon, aromatic polyamide (Kevlar®) or ultra-high molecular weight polyethylene (UHMWPE), and then the rope body 81 or the belt body provides excellent tensile strength and durability at the flat Ω-shaped segment 51, so as to further enhance the tensile strength and structural strength of the high-strength textile suture structure 10 of the present invention.

[0053] As shown in Figure 16, this is the sixth embodiment of the high-strength textile suture structure 10 of the present invention. The embodiment of Figure 16 is roughly the same as the embodiment of Figure 15. The difference between the embodiment of Figure 16 and the embodiment of Figure 15 is that the strip member 8 is a strip sheet 82 or a strip rod.

[0054] As described in detail below, the strip sheet 82 or strip rod is made of metal, polyester (PET), nylon (Nylon), polyurethane (TPU), or polyethylene (PE). Furthermore, the strip sheet 82 or strip rod provides excellent tensile strength and durability at the flat Ω-shaped section 51, thereby further enhancing the tensile strength and structural strength of the high-strength textile suture structure 10 of the present invention.

[0055] In addition, the strip sheets 82 or strip rods made of polyester (PET), nylon (Nylon), polyurethane (TPU) or polyethylene (PE) are lighter and more flexible than the strip sheets 82 or strip rods made of metal. Therefore, if the high-strength textile suture structure 10 of the present invention has a higher rigidity requirement for the sutures, the strip sheets 82 or strip rods made of metal are selected for use. If the high-strength textile suture structure 10 of the present invention has a higher lightweight requirement for the sutures, the strip sheets 82 or strip rods made of polyester (PET), nylon (Nylon), polyurethane (TPU) or polyethylene (PE) are selected for use.

[0056] 15, the strip member 8 is a rope 81, a belt or a strip rod that can be used to centrally enhance the linear strength of the suture, and the strip member 8 is a strip sheet 82 that can be used for large-area suture areas that require dispersed force.

[0057] In summary, the high-strength textile suture structure and its manufacturing method of the present invention are unprecedented in similar products and have not been publicly used. They are industrially applicable, novel, and progressive, and fully meet the requirements for patent applications. Therefore, an application is filed in accordance with the Patent Law to protect the rights of the inventor.
