Description

BACKGROUND OF THE DISCLOSURETechnical Field

[0001] The present disclosure relates to a textile stitched structure, and particularly relates to a high-strength textile stitched structure and a manufacturing method thereof.Description of Art

[0002] Products used for outdoor sports such as fall protection suits, protective gear, and backpacks; military protective applications such as bulletproof vests and stab-resistant suits; and automotive interior applications such as seats and seatbelts often require exceptional tensile strength, tear resistance, and abrasion resistance. Consequently, high-strength textile fabrics are frequently employed in manufacture in order to significantly enhance product safety and durability.

[0003] However, during the sewing process of the aforementioned products, issues such as stitch damage and uneven stitch tension often arise due to the needle and thread penetrating the fabric. This leads to reduced seam strength and causes phenomena like stitch breakage, wear, or fabric tearing. Furthermore, the seams often become the weakest link in the product due to the specific usage characteristics of high-strength textile fabrics. Related-art sewing techniques fail to effectively address the stress issues of stretching and abrasion at the seam, often leading to thread breakage and seam failure. This shortens product lifespan and compromises user safety.

[0004] In view of the aforementioned deficiencies of the related art, the present disclosure has conducted research based on the existing technologies and the application of theories, and finally developed a reasonable design in accordance with the present disclosure to overcome the deficiencies of the related art.SUMMARY OF THE DISCLOSURE

[0005] The present disclosure discloses a high-strength textile stitched structure and manufacturing method thereof, which utilizes a reinforcing fabric, a first stitch, and a second stitch to reinforce the seams of a main fabric to achieve the high tensile strength and tear resistance of the high-strength textile stitched structure.

[0006] In an embodiment of the present disclosure, the present disclosure provides a high-strength textile stitched structure including: a pair of main fabrics, having two first flat sections spaced side-by-side with each other, two first folded sections folded downward from two adjacent sides of the two first flat sections respectively, two extended sections extending from the ends of the two first folded sections and disposed below the two first flat sections respectively, and a seam formed between the two first folded sections; a reinforcing fabric, having a second flat section stacked on top of the two first flat sections, two second folded sections folded downward from two outer sides of the second flat section and passed into the seam, and a remaining section stacked below the two extended sections; a first stitch, for sewing the two first folded sections together with the two second folded sections; and a pair of second stitches, for sewing the left and right sides of the second flat section together with each first flat section, each extended section and the remaining section.

[0007] In an embodiment of the present disclosure, the present disclosure provides a manufacturing method of a high-strength textile stitched structure, and the method includes the steps of: (A) providing a pair of main fabrics, a reinforcing fabric and a first stitch, folding the pair of main fabrics into two first flat sections spaced side-by-side with each other, folding two first folded sections downward from the adjacent sides of the two first flat sections respectively and two extended sections extending from the ends of the two first folded sections and located below the two first flat sections, forming a seam between the two first folded sections, folding the reinforcing fabric into a second flat section stacked on top of the two first flat sections, two second folded sections folded downward from two outer sides of the second flat section and passed into the seam, and a remaining section stacked below the two extended sections, and sewing the two first folded sections together with the two second folded sections through the first stitch; and (B) providing a pair of second stitches, and sewing the left and right sides of the second flat section together with each first flat section, each extended section and the remaining section through the pair of second stitches.

[0008] Based on the description above, the reinforcing fabric is inserted into the seam of the main fabric, and then the first folded section of the main fabric at the seam is sewn together with the second folded section of the reinforcing fabric through the first stitch. Finally, the left and right sides of the second flat section covering the seam of the main fabric are sewn together with each first flat section, each extended section of the reinforcing fabric and the remaining section through the second stitch. This reinforces the seam of the main fabric through the reinforcing fabric, the first stitch and the second stitch, thereby avoiding problems such as stitch breakage, fabric slippage, tearing or seam rupture at the seam of the main fabric, and also provides high tensile strength and tear resistance to the high-strength textile stitched structure of the present disclosure.

[0009] Based on the description above, the reinforcing fabric is an inverted U-shaped fabric or an O-shaped fabric. When the reinforcing fabric is an inverted U-shaped fabric, it is adhered to the adhesive tape to increase structural strength. The adhesive tape improves the friction resistance of the reinforcing fabric, making it suitable for use in areas of clothing with low wear, such as shoulders, back, legs, and chest, thereby giving the high-strength textile stitched structure stronger adaptability and abrasion resistance. When the reinforcing fabric is an O-shaped fabric, its shape provides all-around uniform support and reinforcement, making it suitable for use in key areas of clothing, such as shoulders, back, and legs, thereby enhancing the overall durability and safety of the high-strength textile stitched structure.BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The detailed description and technical contents of the present disclosure are illustrated with reference to the accompanying drawings, which are intended for the illustrative purposes only, but not intended for limiting the disclosure.

[0027] With reference to FIGS. 1 to 6 for a high-strength textile stitched structure and a manufacturing method thereof in accordance with the first embodiment of the present disclosure, the high-strength textile stitched structure 10 includes a pair of main fabrics 1, a reinforcing fabric 2, a first stitch 3, an adhesive tape 6 and a pair of second stitches 4.

[0028] With reference to FIGS. 1 and 2 for the steps of the manufacturing method of a high-strength textile stitched structure 10 in accordance with the first embodiment of the present disclosure, the first step (as shown in Step S11 of FIGS. 1 and 3) provides a pair of main fabrics 1, a reinforcing fabric 2 and a first stitch 3, folds the pair of main fabrics 1 to form two first flat sections 11 spaced side-by-side with each other, two first folded sections 12 folded downward from the adjacent sides of the two first flat sections 11, two extended sections 13 extending from the ends of the two first folded sections 12 and located below two first flat sections 11, and a seam formed between the two first folded sections 12, and folds the reinforcing fabric 2 to form a second flat section 21 stacked on top of the two first flat sections 11 and covering the seam S, two second folded sections 22 folded downward from two outer sides of the second flat section 21 and passed into the seam S, and a remaining section 23 stacked below the two extended sections 13, and sews the two first folded sections 12 together with the two second folded sections 22 through a first stitch 3, that is, the two first folded sections 12 and the two second folded sections 22 are sewn together through the first stitch 3, the second flat section 21 is a flat Ω-shaped section 51, and the remaining section 23 is composed of two one-line sections 52 stacked below each extended section 13.

[0029] In some embodiments, the main fabric 1 is a high-strength fabric, but is not limited thereto, and the high-strength fabric is made of at least one selected from the group of a high-strength abrasion-resistant nylon fiber (such as CORDURA®), a high-strength polyethylene terephthalate fiber (PET), an aromatic polyamide fiber (such as Kevlar®), an ultra-high molecular weight polyethylene fiber (UHMWPE), a liquid crystal polymer fiber (such as Vectran®), and a carbon fiber.

[0030] In some embodiments, the main fabric 1 is made of a plain weave woven fabric with a material composition of 84.2% nylon fiber, 6.8% liquid crystal polymer fiber and 9% thermoplastic polyurethane coated. This plain weave woven fabric has a warp density of 69 ends per inch and a weft density of 47 ends per inch, wherein each inch of weft yarn contains 8 liquid crystal polymer fiber yarns, and the plain weave woven fabric has a weight of 215 g / m2 and a thickness of 0.55 mm, so that the main fabric 1 has excellent strength and durability to meet the high strength requirements of outdoor sports applications such as fall protection suits, protective gear, and backpacks, military protective applications such as bulletproof vests and puncture-resistant suits, and automotive interior applications such as seats and seat belts.

[0031] The reinforcing fabric 2 is made of high-strength synthetic fibers, such as nylon, polyethylene terephthalate, or high-performance fibers with special functions. In some embodiments, the reinforcing fabric 2 is made of nylon plain weave fabrics with a warp density of 112 ends per inch, a weft density of 94 ends per inch, a fabric weight of 272 g / m², and a thickness of 0.53 mm to provide stable and durable structural support for the seam.

[0032] The manufacturing method of the present disclosure is further elaborated as follows. Firstly, as shown in FIG. 2, the step S11 sequentially includes a step S21, a step S22 and a step S23. In the step S21, the reinforcing fabric 2 is formed by an inverted U-shaped fabric 5 horizontally arranged between the pair of vertically stacked main fabrics 1. As shown in the step S22, the inverted U-shaped fabric 5 is sewn together with the pair of main fabrics 1 through the first stitch 3. Finally, as shown in the step S23, the two first flat sections 11, the two first folded sections 12 and the two extended sections 13 are folded and formed from the pair of main fabrics 1, such that the inverted U-shaped fabric 5 is passed into the seam S, and then the top end of the inverted U-shaped fabric 5 is pressed and flattened to form a flat Ω-shaped section 51, and two one-line sections 52 are folded and formed from the two bottoms of the inverted U-shaped fabric.

[0033] Secondly, as shown in the step S12 of FIGS. 1 and 4, the manufacturing method of the present disclosure provides an adhesive tape 6, adheres the adhesive tape 6 below the two one-line sections 52 and covers the seam S. In some embodiments, the adhesive tape 6 is either a hot-press fusion tape or a cold-press pressure-sensitive tape. The hot-press fusion tape is melted and bonded at high temperatures, while the cold-press pressure-sensitive tape is cold-

[0034] pressed and bonded at room temperature to improve the adhesion strength with the reinforcing fabric 2 and prevent the seams from peeling or delaminating during use. The adhesive tape 6 uses either a single-sided fabric tape or a plastic film tape to ensure that it is suitable for high-strength fabrics and has excellent abrasion resistance, tensile strength, and thermal stability.

[0035] In some embodiments, the adhesive tape 6 is a fabric TPU hot melt adhesive tape with a thickness of 0.4mm, and capable of performing a hot press treatment at a temperature of 150°C and a pressure of 5kg / cm² for 20 seconds to ensure that the fabric TPU hot melt adhesive tape is firmly bonded to the reinforcing fabric 2, thereby further improving the strength and durability of the seam.

[0036] Thirdly, as shown in FIG. 3, the step S13 of FIGS. 1, 5 and 6, the manufacturing method of the present disclosure provides a pair of second stitches 4 to sew the left and right sides of the second flat section 21 together with each first flat section 11, each extended section 13 and the remaining section 23. In other words, 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 each first flat section 11, each extended section 13 and each one-line section 52 through the pair of second stitches 4.

[0037] The adhesive tape 6 is mainly for increasing the structural strength of the inverted U-shaped fabric 5, but it is not a necessary component of the high-strength textile stitched structure 10 of the present disclosure. In some embodiments, the adhesive tape 6 is omitted depending on the actual situation. In other words, the adhesive tape 6 below the two one-line sections 52 is also omitted, and only the left and right sides of the flat Ω-shaped section 51 are sewn together with each first flat section 11, each extended section 13 and each one-line section 52 through the pair of second stitches 4.

[0038] In FIGS. 5 and 6, a using status of the high-strength textile stitched structure 10 in accordance with an embodiment of the present disclosure is shown, wherein the reinforcing fabric 2 is inserted through the seam S of the main fabric 1, and then the first folded section 12 of the main fabric 1 at the seam S is sewn together with the second folded section 22 of the reinforcing fabric 2 through the first stitch 3. Since the reinforcing fabric 2 of this embodiment is an inverted U-shaped fabric 5, it is bonded to the adhesive tape 6 to increase structural strength.

[0039] However, the adhesive tape 6 is not a necessary component and is omittable. Finally, the second stitch 4 is provided for connecting the left and right sides of the second flat section 21 of the main fabric 1 that covers the seam S to each first flat section 11, and each extended section 13 of the reinforcing fabric 2 to the remaining section 23 and adhesive tape 6. In this way, the seams of the main fabric 1 are reinforced by the reinforcing fabric 2, the first stitch 3, and the second stitch 4 to prevent problems such as stitch breakage, fabric slippage, tearing, or seam rupture at the seams of the main fabric 1 and achieve the high-strength textile stitched structure 10 with high tensile strength and tear resistance.

[0040] The reinforcing fabric 2 of this embodiment is an inverted U-shaped fabric 5, and the inverted U-shaped fabric 5 is bonded to the adhesive tape 6 to increase structural strength. The adhesive tape 6 improves the friction resistance of the reinforcing fabric 2, making it suitable for use in areas of clothing with low wear, such as shoulders, back, legs, and chest, so that the high-strength textile stitched structure 10 has stronger adaptability and better wear resistance.

[0041] With reference to FIGS. 7 and 8 for a high-strength textile stitched structure 10 in accordance with the second embodiment, of the present disclosure, this embodiment is substantially the same as the first embodiment as shown in FIGS. 1 to 6, except that the high-strength textile stitched structure 10 of this embodiment further includes a one-line piece 8.

[0042] The details are described as follows. The one-line piece 8 is passed into a flat Ω-shaped section 51. The one-line piece 8 is a string 81 or a strip, but is not limited thereto. The string 81 or strip is made of high-strength fibers such as polyethylene terephthalate, nylon, aromatic polyamide (Kevlar®), or ultra-high molecular weight polyethylene (UHMWPE) to provide excellent tensile strength and durability at the flat Ω-shaped section 51 through the string 81 or strip, and further enhance the tensile strength and structural strength of the high-strength textile stitched structure 10.

[0043] With reference to FIG. 9 for a high-strength textile stitched structure 10 in accordance with the third embodiment of the present disclosure, this embodiment is substantially the same as the embodiments shown in FIG. 7 and 8, except that the one-line piece 8 of this embodiment is a strip plate 82 or a bar.

[0044] Further elaboration is provided below: the strip plate 82 or bar is made of metal, polyethylene terephthalate (PET), nylon, thermoplastic polyurethane (TPU), or polyethylene (PE) to provide excellent tensile strength and durability at the flat Ω-shaped section 51 through the strip plate 82 or bar and further enhance the tensile strength and structural strength of the present disclosure high-strength textile stitched structure 10.

[0045] The strip plates 82 or bars made of polyethylene terephthalate (PET), nylon, thermoplastic polyurethane (TPU), or polyethylene (PE) are lighter and more flexible than the strip plates 82 or bars made of metal. Since the high-strength textile stitched structure 10 of the present disclosure has a high requirement for the rigidity of the stitches, therefore strip plates 82 or bars made of metal are selected for use. Since the high-strength textile stitched structure 10 of the present disclosure also has a high requirement for the lightweight of the stitches, therefore the strip plates 82 or bars made of polyethylene terephthalate (PET), nylon, thermoplastic polyurethane (TPU), or polyethylene (PE) are selected for use.

[0046] Referring again to the embodiment as shown in FIGS. 7 and 8, the one-line piece 8 is a string 81, strip or bar used to concentrate the linear strength of the stitch, and the one-line piece 8 is a strip plate 82 used for large stitch areas where the force needs to be distributed.

[0047] With reference to FIGS. 10 to 14 for a high-strength textile stitched structure 10 in accordance with the fourth embodiment of the present disclosure, this embodiment is substantially the same as the embodiment as shown in FIGS. 1 to 6 except that the steps of the manufacturing method of this embodiment are different.

[0048] With reference to FIGS. 10 and 11 for the steps of the manufacturing method of the high-strength textile stitched structure 10 in accordance with the fourth embodiment of the present disclosure, firstly, as shown in the step S31 of FIGS. 10 and 12, the manufacturing method of this embodiment provides the pair of main fabrics 1, reinforcing fabric 2 and first stitch 3, folding the pair of main fabrics 1 to form two first flat sections 11 spaced side-by-side with each other, two first folded sections 12 folded downward from the adjacent sides of the two first flat sections 11, two extended sections 13 extending from the ends of the two first folded sections 12 and located below two first flat sections 11, and a seam S formed between the two first folded sections 12. The manufacturing method further folds the reinforcing fabric 2 to create a second flat section 21 stacked on top of the two first flat sections 11 and covering the seam S, and folds the two outer sides of the second flat section 21 downwards and passes it through the seam S to create two second folded sections 22, and then folds the remaining section 23 which is stacked on top of the two extended sections 13, and sews the two first folded sections 12 and the two second folded sections 22 together with the first stitch 3, wherein 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.

[0049] The details are further elaborated as follows. As shown in FIG. 11, the step S31 includes a step S41, a step S42 and a step S43 in sequence. Firstly, as shown in the step S41, the reinforcing fabric 2 of this embodiment is composed of an O-shaped fabric 7 that is horizontally arranged between the pair of vertically stacked main fabrics 1. Furthermore, as shown in step S42, the O-shaped fabric 7 is sewn together with the pair of main fabrics 1 through the first stitch 3; finally, as shown in step S43, the two first flat sections 11, two first folded sections 12, and two extended sections 13 are folded out from the pair of main fabrics 1, so that the O-shaped fabric 7 is passed into the seam S, and then the top of the O-shaped fabric 7 is pressed and flattened to form a flat Ω-shaped section 71, and the bottom of the O-shaped fabric 7 is pressed and flattened to form a flat inverted Ω-shaped section 72.

[0050] Secondly, as shown in the step S32 of FIGS. 10, 13 and 14, the manufacturing method of this embodiment provides a pair of second stitches 4, and sews the left and right sides of the second flat section 21 together with each first flat section 11, each extended section 13 and the remaining section 23 through the pair of second stitches 4. In other words, the left and right sides of the flat inverted Ω-shaped section 72 and the left and right sides of the flat Ω-shaped section 71 are sewn together with each first flat section 11 and each extended section 13 through the pair of second stitches 4.

[0051] With reference to FIGS. 13 and 14 for a high-strength textile stitched structure 10 in accordance with the fourth embodiment of the present disclosure, the reinforcing fabric 2 is inserted into the seam S of the main fabric 1, then the first folded section 12 of the main fabric 1 at the seam S is sewn together with the second folded section 22 of the reinforcing fabric 2 through the first stitch 3, and finally the left and right sides of the second flat section 21 of the main fabric 1 are sewn to cover the seam S with each first flat section 11, and each extended section 13 of the reinforcing fabric 2 is sewn together with the remaining section 23 through the second stitch 4. In this way, the seams of the main fabric 1 are reinforced by the reinforcing fabric 2, the first stitch 3 and the second stitch 4 to prevent problems such as stitch breakage, fabric slippage, tearing or seam rupture at the seams of the main fabric 1 and achieve high tensile strength and tear resistance of the high-strength textile stitched structure 10 of the present disclosure.

[0052] The reinforcing fabric 2 of this embodiment is an O-shaped fabric 7. The O-shaped fabric 7 provides all-round uniform support and reinforcement due to its shape, thus making it suitable for use in key parts of clothing, such as the shoulders, back and legs, and enhancing the overall durability and safety of the high-strength textile stitched structure 10 of the present disclosure.

[0053] With reference to FIG. 15 for a high-strength textile stitched structure 10 in accordance with the fifth embodiment of the present disclosure, this embodiment is substantially the same as the embodiment as shown in FIGS. 10 to 14, except that the high-strength textile stitched structure 10 of this embodiment further includes one or more one-line pieces 8.

[0054] The present disclosure is further elaborated as follows. In some embodiments, the one-line piece 8 is passed into at least one of the flat Ω-shaped section 71 and the flat inverted Ω-shaped section 72, that is, two one-line pieces 8 are passed into the flat Ω-shaped section 71 and the flat inverted Ω-shaped section 72 respectively, or one one-line piece 8 is passed into either the flat Ω-shaped section 71 or the flat inverted Ω-shaped section 72. In some embodiments, the one-line piece 8 is a string 81 or a strip, but is not limited thereto. The string 81 or strip is made of high-strength fibers such as polyethylene terephthalate, nylon, aromatic polyamide (Kevlar®), or ultra-high molecular weight polyethylene (UHMWPE) to provide excellent tensile strength and durability at the flat Ω-shaped section71 through the string 81 or strip and further enhance the tensile strength and structural strength of the high-strength textile stitched structure 10.

[0055] With reference to FIG. 16 for a high-strength textile stitched structure 10 in accordance with the sixth embodiment of the present disclosure, this embodiment is substantially the same as the embodiment as shown in FIG. 15, except that the one-line piece 8 of the high-strength textile stitched structure 10 of this embodiment is a strip plate 82 or a bar.

[0056] The strip plate 82 or bar is made of metal, polyethylene terephthalate (PET), nylon, thermoplastic polyurethane (TPU), or polyethylene (PE) to provide excellent tensile strength and durability at the flat Ω-shaped section 71 through the strip plate 82 or bar, and further enhance the tensile and structural strength of the high-strength textile stitched structure 10.

[0057] Furthermore, the strip plates 82 or bars made of polyethylene terephthalate (PET), nylon, thermoplastic polyurethane (TPU), or polyethylene (PE) are lighter and more flexible than the strip plates 82 or bars made of metal. Since the high-strength textile stitched structure 10 of the present disclosure has a high requirement for the rigidity of the stitches, therefore the strip plates 82 or bars made of metal are selected for use. Since the high-strength textile stitched structure 10 of the present disclosure also has a high requirement for the lightweight of the stitches, therefore the strip plates 82 or bars made of polyethylene terephthalate (PET), nylon, thermoplastic polyurethane (TPU), or polyethylene (PE) are selected for use.

[0058] Furthermore, referring to the embodiment as shown in FIG. 15 again, the one-line piece 8 is a string 81, a strip or a bar used to concentrate and enhance the linear strength of the stitch, and the one-line piece 8 is a strip plate 82 used for large stitch areas where force needs to be dispersed.

[0059] The above examples merely represent preferred embodiments of the present disclosure and they are not intended to limit the scope of the present disclosure. Therefore, any equivalent techniques, means, or variations made by utilizing the content of the specification and drawings of the disclosure are likewise included within the scope of the present disclosure.
