The first organization 1 can also be understood as a structure formed by a weaving method, that is, the first organization 1 is formed by interweaving a plurality of groups of first warp yarns 10 and first weft yarns 20 perpendicular to each other. The chain stitch organization 3 has a looped knitting structure, and can be arranged along each first warp yarn 10 in the longitudinal direction, sequentially passing through each first organization point on the first warp yarn 10 and being arranged, thereby strengthening the fixed connection between the first warp yarn 10 and the first weft yarn 20, reducing the extensibility of the lining yarn unit in the longitudinal and transverse directions, and improving the overall stability of the fabric structure.

The oblique direction includes the first direction and the second direction, and the second organization 2 intersects in the first direction and the second direction to form a plurality of second intersection points, and then the second organization 2 is coupled with the first organization 1, so that the second organization 2 intersects with the first warp yarn 10 to form a second intersection point, and the chain stitch organization 3 is arranged on the second intersection point sequentially passed by the first warp yarn 10 while being arranged on the above-mentioned first organization point, thereby strengthening the fixed connection between the first warp yarn 10 and the second organization 2, and the stability inside the second organization 2, to reduce the extensibility of the lining yarn unit in the oblique direction.
[0031] It should be noted that, as shown, Fig. 3 The above-mentioned "coupling" of the coupling of the second organization 2 with the first organization 1 includes the connection mode of the second organization 2 passing through at least one first warp yarn 10 or first weft yarn 20 in the first organization 1 in an up-down alternating manner, and also includes the connection relationship of the second organization 2 directly covering the first organization 1.
[0032] In summary, the fabric structure adopts a multi-axial fabric structure to combine the braiding structure of the chain stitch 3 with the warp-weft interweaving structure of the first stitch 1, and introduces the second stitch 2 obliquely on the basis of the first stitch 1, forms a multi-axial lining yarn unit, so that it also has good mechanical properties in the oblique direction. At the same time, the chain stitch 3 can fix the multi-axial lining yarn unit, so as to avoid the lining yarn unit from slipping, and the lining yarn unit of the fabric structure can form a larger open hole structure due to the use of the weave structure, thereby improving the air permeability and toughness of the fabric structure. In addition, based on the above structural characteristics, the application of the multi-axial fabric structure on the vamp fabric has its own advantages, the yarn has strong universality by using the fabric structure, the yarn diameter is applicable in the range of 0.1mm to 1mm, and even can be thicker, the porosity between the lining yarn units can be adjusted according to the density of the first stitch 1 or the second stitch 2, and a special fabric appearance and style are obtained, and the porosity can realize the air permeability improvement and light weight effect of the whole fabric structure.
[0033] In order to better understand the purpose, structure and function of the utility model, the fabric structure will be further described in detail below with reference to the drawings and taking the specific structure of the fabric structure as an example.
[0034] As shown in Figs. 1 to 3 The fabric structure includes a lining yarn unit and a chain stitch 3, the lining yarn unit includes a first stitch 1, the first stitch 1 includes a plurality of first warp yarns 10 arranged longitudinally, a plurality of first weft yarns 20 arranged transversely, and a plurality of first stitch points formed by the interweaving of the first warp yarns 10 and the first weft yarns 20. It should be noted that the above longitudinal and transverse directions include not only the first warp yarns 10 and the first weft yarns 20 arranged completely vertically, but also the structure arranged with some offset angle, as long as the first stitch 1 can form a weave structure.
[0035] The first stitch 1 is formed by the interweaving of the first warp yarns 10 and the first weft yarns 20. When such an interweaving structure is subjected to an external force, the first warp yarns 10 and the first weft yarns 20 are prone to relative sliding, i.e. slipping phenomenon, which will cause defects on the surface of the fabric, affecting the quality and appearance of the fabric. In severe cases, slipping may also cause the fabric structure to loosen, reducing the durability of the fabric.
[0036] The chain stitch 3 is formed by a group of longitudinal yarns, each group of chain stitches 3 is arranged along each first warp yarn 10 and arranged on a plurality of first stitch points through which the first warp yarn 10 sequentially passes. The first warp yarn 10 and the first stitch points of the first stitch 1 are fixed by the chain stitch 3, which can strengthen the connection between the first warp yarn 10 and the first weft yarn 20 and improve the overall stability of the fabric. In addition, the chain stitches 3 are interwoven in a ring shape, which increases the contact area and friction between the yarns, thereby improving the stability of the first stitch 1. The above characteristics of stability and high friction of the chain stitch 3 can effectively reduce the relative sliding between the first warp yarn 10 and the first weft yarn 20, reduce the extensibility of the lining yarn unit in the longitudinal and transverse directions, and further avoid the occurrence of the first stitch 1 slipping phenomenon.
[0037] Preferably, the lining yarn unit includes the first stitch 1 and the second stitch 2 arranged obliquely, the second stitch 2 of the lining yarn unit includes a plurality of first yarns 30 arranged in the first direction and a plurality of second yarns 40 arranged in the second direction, the first yarns 30 and the second yarns 40 are arranged alternately to form a plurality of third intersection points. The first yarns 30 are alternately arranged above and below the first stitch 1, and the second yarns 40 are alternately arranged above and below the first stitch 1. The above-mentioned and below-mentioned arrangement of the first yarns 30 and the second yarns 40 on the first stitch 1 enables the second stitch 2 to be relatively stably fixed on the first stitch 1, improves the overall structural strength of the fabric structure, and enables the second stitch 2 to be in close contact with the first stitch 1, thereby facilitating subsequent processing and manufacturing.
[0038] It should be noted that the above-mentioned and below-mentioned arrangement of the first yarns 30 and the second yarns 40 on the first stitch 1 means that the first yarns 30 and the second yarns 40 are arranged above at least one first warp yarn 10 or first weft yarn 20 and below at least one first warp yarn 10 or first weft yarn 20, thereby increasing the friction and adhesion between the first yarns 30 and the second yarns 40 and the first warp yarn 10 and the first weft yarn 20, and further achieving the effect of close contact between the first yarns 30 and the second yarns 40 and the first stitch 1. It can be understood that the above-mentioned effect can also be basically achieved by directly arranging the second stitch 2 on the first stitch 1 and fixing the second stitch 2 and the first warp yarn 10 by the chain stitch 3.
[0039] Preferably, the first yarn 30 intersects with the first weft yarn 20 to form a plurality of fourth intersection points 50, the first yarn 30 alternately intersects with the first warp yarn 10 and the first weft yarn 20, thereby forming a plurality of second intersection points, the second intersection points and the fourth intersection points 50 on each first yarn 30 are arranged alternately, the first yarn 30 is arranged below all the first warp yarn 10 and above all the first weft yarn 20, thereby forming a structure that the first yarn 30 is alternately arranged above and below the second intersection points and the fourth intersection points 50 through which the first yarn 30 sequentially passes, the second yarn 40 intersects with the first weft yarn 20 to form a plurality of fourth intersection points 50, the second yarn 40 alternately intersects with the first warp yarn 10 and the first weft yarn 20, thereby forming a plurality of second intersection points, the second intersection points and the fourth intersection points 50 on each second yarn 40 are arranged alternately, the second yarn 40 is arranged below all the first warp yarn 10 and above all the first weft yarn 20, thereby forming a structure that the second yarn 40 is alternately arranged above and below the second intersection points and the fourth intersection points 50 through which the second yarn 40 sequentially passes. It can be understood that the arrangement of the second structure 2 on the second intersection points and the fourth intersection points 50 can be interchanged, and the fixing effect is the same, which can enhance the fit and stability of the connection between the second structure 2 and the first structure 1.
[0040] The second structure 2 is arranged above and below the first structure 1, and then the second structure 2 intersects with each first warp yarn 10 to form a plurality of second intersection points, and the binder structure 3 is arranged on the first warp yarn 10 and sequentially arranged on the first structure points and the second intersection points through which the first warp yarn 10 passes. By fixing the first warp yarn 10 and the second intersection points of the first structure 1 through the binder structure 3, the connection between the first warp yarn 10 and the second structure 2 can be strengthened, and the overall stability of the fabric can be improved. In addition, the binder structure 3 is interwoven in a ring shape, which increases the contact area and friction between the second structure 2 and the first structure 1, thereby improving the stability of the first structure 1. Through the above characteristics of the stability and large friction of the binder structure 3, the oblique relative sliding between the first warp yarn 10 and the first weft yarn 20 can be effectively reduced, so as to reduce the extensibility of the base yarn unit in the oblique direction, and make the fabric structure also have good mechanical properties and stability in the oblique direction.
[0041] Further, the third intersection points are arranged on the first warp yarn 10, that is, the third intersection points are arranged coincidentally with the second intersection points, and the binder structure 3 is arranged on the first warp yarn 10 and the first structure points and the third intersection points through which the first warp yarn 10 sequentially passes. By fixing the third intersection points of the second structure 2 on the first warp yarn 10 through the binder structure 3, the stability between the first yarn 30 and the second yarn 40 is enhanced, which helps to improve the mechanical properties of the overall structure of the fabric structure.
[0042] Specifically, as Fig. 3As shown, the chain stitch organization 3 includes a second warp yarn, the second warp yarn is arranged to form a plurality of loops, the loops are sequentially arranged on the first warp yarn 10 and the first organization point, the second intersection or the third intersection sequentially passed by the first warp yarn 10, and the first warp yarn 10, the first weft yarn 20, the first yarn 30 and the second yarn 40 are bound by the loops, so that the stability of the fabric structure is obtained.
[0043] Further, the angle of the transverse direction of the fabric structure is defined as 0°, the angle of the longitudinal direction is defined as 90°, the included angle between the first direction and the transverse direction is set as the first included angle, and the included angle between the second direction and the transverse direction is set as the second included angle, the first included angle is set as 30° to 60°, and the second included angle is set as -30° to -60°, the inclination angle of the second organization 2 is set in the angle range, so that the mechanical properties of the first group of components in the oblique direction are effectively improved, preferably, the first included angle is set as 45°, and the second included angle is set as -45°, so that the first yarn 30 and the second yarn 40 obtain relatively balanced stability on both sides of the direction, and the oblique stability of the fabric structure is improved.
[0044] The first warp yarn 10 and the first weft yarn 20 are set as a single filament, the first warp yarn 10 and the first weft yarn 20 are set as a single filament of 1500D, the diameter of the first warp yarn 10 and the first weft yarn 20 is 0.1mm to 1.0mm, the first yarn 30 and the second yarn 40 are set as a multifilament of 1000D / 96F, the chain stitch organization 3 includes a second warp yarn, the second warp yarn is set as two single filaments of 100D, and the diameter of the second warp yarn is 0.1mm to 0.2mm.
[0045] It should be noted that the second warp yarn of the chain stitch organization 3 mainly plays an anchoring role on the first organization 1 and the second organization 2 in the fabric structure, and is set to be weakened in appearance for improving the aesthetic degree, therefore, two single filaments with high transparency are adopted, the two single filaments are arranged in parallel to constitute the chain stitch organization 3, the material has hot melting property, after high-temperature setting, the two single filaments are bonded to each other, so as to enhance the structural strength of the chain stitch organization 3.
[0046] The first warp yarn 10, the first weft yarn 20 and the second warp yarn adopt hot melting materials, for example, polyurethane elastomer, nylon elastomer, polyester, nylon, aramid, polyimide and the like, preferably, the second warp yarn adopts a hot melting single filament of thermoplastic polyurethane 120℃ low temperature, the first yarn 30 and the second yarn 40 adopt heat-resistant materials, for example, polyester and acrylic. Since the first warp yarn 10, the first weft yarn 20 and the second warp yarn adopt hot melting materials, they can be pretreated by hot air, hot pressing and the like, so as to enhance the stability of the fabric structure.
[0047] It can be understood that, due to the characteristics of low extension and high strength of the first weave 1 of the woven structure, the stitching weave 3 needs to be continuously looped to form a stable structure, and the stitching weave 3 requires high yarns, and the commonly used stitching weave 3 yarns have a diameter of about 150D, and the yarn types are limited. The stitching weave 3 described above plays an anchoring role on the first weave 1 in the fabric structure, fixes the first warp yarn 10 and the first weft yarn 20, avoids yarn slippage, and in use, the yarn is mainly transparent monofilament, which weakens the appearance, thereby further expanding the performance advantages of the first weave 1 and improving the diameter application range of the second warp yarn in the stitching weave 3.

[0049] 1. By arranging the lining yarn unit with the woven structure and the stitching weave, the stitching weave has a yarn looped weaving structure, and the first warp yarn on the lining yarn unit and the intersection of the woven structure are arranged, thereby strengthening the fixed connection between the lining yarn units, reducing the extensibility of the lining yarn unit in the longitudinal and transverse directions, and improving the overall stability of the fabric structure.
[0050] 2. By coupling the oblique second weave with the first weave, the second weave intersects with the first warp yarn to form a second intersection, and the stitching weave is arranged on the second intersection through which the first warp yarn passes in sequence while being arranged on the first weave point, thereby reducing the extensibility of the lining yarn unit in the oblique direction, strengthening the fixed connection between the first warp yarn and the second weave, and improving the stability of the second weave.
[0051] 3. The porosity between the lining yarn units can be adjusted according to the density of the first weave or the second weave, and a unique fabric appearance and style can be obtained, and the porosity can realize the overall air permeability and lightweight effect of the fabric structure.
