[0031] Referring to Figure 1, this utility model provides a warp-knitted multidimensional fabric, which includes a weft weft yarn 10, a first oblique weft yarn 20, a second oblique weft yarn 30, and a ground yarn 40; the weft weft yarn 10 is padded in the weft direction; the first oblique weft yarn 20 is padded on one side of the weft weft yarn 10 and forms an angle with the weft weft yarn 10; the second oblique weft yarn 30 is padded on the other side of the weft weft yarn 10 and forms an angle with the weft weft yarn 10; the ground yarn 40 is woven in the radial direction and wraps around the weft weft yarn 10, the first oblique weft yarn 20, and the second oblique weft yarn 30 to form a warp plain weave.

[0032] Using 0° in the warp direction as a reference, the first oblique weft yarn 20 is laid in a direction of 0° to 90°, and the second oblique weft yarn 30 is laid in a direction of 0° to -90°. The ground yarn 40 interweaves the weft yarn 10, the first oblique weft yarn 20, and the second oblique weft yarn 30 for continuous weaving, forming a warp-plain weave structure. The weft yarn 10, the first oblique weft yarn 20, and the second oblique weft yarn 30 are inserted into the fabric from different directions, forming three textile layers. At the same time, by varying the number of loops in the weft yarn 10, the first oblique weft yarn 20, and the second oblique weft yarn 30, different openwork textures and appearances are formed, which can be adaptively adjusted according to actual production needs.

[0033] The plain weave is one of the basic weaves of warp knitting, characterized by the fact that the loops formed by the same warp yarn are alternately arranged in two adjacent loops. The loops can be open or closed. The plain weave is formed by alternating the insertion of each warp yarn on two adjacent needles. There are two courses in a complete stitch. Due to the bending of the yarn at the junction of the loop and the extension line, the loop body tilts in the opposite direction of the extension line under the elastic restoring force, causing the loop column to be in a zigzag state in the fabric. In addition, due to the extension line passing through the loop arc pressing one side of the loop column, the loop is turned into a plane perpendicular to the plane of the knitted fabric, so that the appearance of the two sides of the fabric is similar. When a loop breaks and is stretched in the transverse direction, the loop will gradually unravel from the broken yarn along the inverse knitting direction of the longitudinal row, causing the fabric to separate into two unconnected pieces. When the plain weave is stretched in the longitudinal or transverse direction, the fabric has a certain elongation due to the change in the inclination angle of the loop and the transfer of the yarn in the loop and the elongation of the yarn itself.

[0034] The first diagonal weft yarn 20 forms an angle of 45°-60° with the weft weft yarn 10, that is, the insertion is in the direction of 45°-60°; the second diagonal weft yarn 30 forms an angle of -45°-60° with the weft weft yarn 10, that is, the insertion is in the direction of -45°-60°; the setting of such an angle can prevent the related interference of the guide bar during the insertion movement, and at the same time, the setting of such an angle can form a better support structure for the weft yarn in the fabric, effectively enhancing the tensile strength of the fabric and preventing the fabric from being damaged or deformed due to external stretching. Of course, the above technical solution can also include a warp weft yarn, which is inserted in the direction of 0°, that is, forms an angle of 90° with the weft weft yarn 10.

[0035] The ground yarn 40 is knitted in a full-insertion manner, so that the fabric has good longitudinal and transverse elongation 。 Full insertion refers to the process of inserting the ground yarn 40 into each needle position during knitting. A threading machine or device is provided to ensure that each yarn is accurately inserted into each needle position. According to the specifications of the chain knitting machine and the type of fabric to be produced, the parameters of the knitting equipment, including yarn tension and needle spacing, are adjusted. Start the chain knitting machine to ensure that the ground yarn 40 passes smoothly through each needle position, forming a uniform and consistent knitting structure. The full-insertion knitting of the ground yarn 40 can significantly enhance the overall strength and durability of the fabric, making it less prone to tearing and wear. During the knitting process, each ground yarn 40 participates in knitting, making the fabric structure more stable and less prone to deformation and wrinkling. Uniform yarn distribution makes the fabric surface smoother and more aesthetically pleasing.

[0036] The weft yarns 10, the first and second diagonal weft yarns 20, 30 have at least one characteristic different from the ground yarns 40; the characteristic includes the elongation at break, the elongation at break of the weft yarns 10, the first and second diagonal weft yarns 20, 30 is greater than that of the ground yarns 40.

[0037] The lower elongation of the ground yarns 40 can increase the stability of the fabric in the longitudinal direction, reduce the risk of longitudinal deformation of the fabric during use, help to evenly distribute stress during stretching, improve the overall tensile strength and durability of the fabric, the greater elongation of the weft yarns 10, the first and second diagonal weft yarns 20, 30 enables them to better adapt and disperse stress during fabric processing, thereby reducing the occurrence of wrinkles and rolled edges, improving the surface flatness of the fabric, making the fabric softer and more elastic, improving the hand feeling, enhancing the drape of the fabric, and making it more beautiful in appearance. The difference in elongation between the ground yarns 40 and the weft yarns can optimize tension control during weaving, reduce the occurrence of broken yarns and fabric defects, and improve production efficiency and yield.

[0038] The ground yarns 40 have at least one characteristic different from the weft yarns 10, the first and second diagonal weft yarns 20, 30; the characteristic includes the breaking strength, the breaking strength of the ground yarns 40 is greater than that of the weft yarns 10, the first and second diagonal weft yarns 20, 30.

[0039] In some embodiments, the breaking strength of the first and second diagonal weft yarns 20, 30 is greater than that of the weft yarns 10, enhancing the transverse strength and support of the warp-knitted multi-dimensional fabric; in some embodiments, the breaking strength of the weft yarns 10 is greater than that of the first and second diagonal weft yarns 20, 30, enhancing the two diagonal strengths and support of the warp-knitted multi-dimensional fabric; the ground yarns 40 with different breaking strengths can be selected according to specific needs, realizing the change of the structure and effect of the warp-knitted multi-dimensional fabric, and meeting the needs of different markets and consumers.

[0040] In some embodiments, the weft yarns 10, the first and second diagonal weft yarns 20, 30 have an elongation at break of at least 2.5 cN / D, and the ground yarns 40 have an elongation at break of at least 4 cN / D.

[0041] The breaking strength represents the force (strength) that the fiber or yarn can withstand at the time of breaking per unit density (D), and the unit is cN, which represents centinewton, the unit of force in the International System of Units, equal to 0.01 newton. Therefore, the breaking strength of 2.5 cN / D means that the fiber or yarn per unit density can withstand more than 2.5 centinewtons of force at the time of breaking. Preferably, the breaking strength of the ground yarn 40 is not less than 4 cN / D, which can increase the overall strength of the warp-knitted multi-dimensional fabric as a chain material, making it more able to withstand external stretching and resist friction and wear in daily use, prolonging the service life of the warp-knitted multi-dimensional fabric, while providing better support and structural stability for the warp-knitted multi-dimensional fabric, helping to increase the stability and structural strength of the warp-knitted multi-dimensional fabric. Similarly, the breaking strength of the weft ground weft yarn 10, the first diagonal ground weft yarn 20 and the second diagonal ground weft yarn 30 is preferably not less than 2.5 cN / D, the weft ground weft yarn 10 can provide good support and structural stability in the weft direction, increase the toughness of the weft direction, help to increase the stability and structural strength of the warp-knitted multi-dimensional fabric, make it more able to withstand external stretching and resist friction and wear in daily use, prolong the service life of the warp-knitted multi-dimensional fabric, the first diagonal ground weft yarn 20 and the second diagonal ground weft yarn 30 make it have better tensile strength, can increase the strength and wear resistance of the warp-knitted multi-dimensional fabric. The first diagonal ground weft yarn 20 and the second diagonal ground weft yarn 30 can provide good support and structural stability in two diagonal directions (at an angle to the weft direction), increase the toughness of the diagonal direction, help to increase the stability and structural strength of the warp-knitted multi-dimensional fabric, and as a diagonal material can increase the overall strength of the warp-knitted multi-dimensional fabric, making it more able to withstand external stretching and resist friction and wear in daily use, prolonging the service life of the warp-knitted multi-dimensional fabric.

[0042] The ground yarn 40 at least comprises a polyester monofilament or a composite monofilament comprising a polyester monofilament. The polyester monofilament is a single continuous filament made of polyester (polyethylene terephthalate) material. It has high strength, high wear resistance, chemical corrosion resistance and low moisture absorption. Polyester monofilament is commonly used in industries, clothing, home textiles and other fields. The composite yarn comprising polyester monofilament is a mixture or composite of polyester monofilament and other fibers or materials such as cotton, wool, nylon, etc., forming a yarn with multiple properties. This composite yarn combines the excellent properties of polyester and the properties of other materials, widening its application range. The ground yarn 40 uses polyester monofilament or composite yarn containing polyester monofilament, which has the advantages of high strength and durability, chemical resistance, low moisture absorption, dimensional stability, easy chemical processing, environmental protection, etc., can significantly improve the performance and service life of the product, meet various application requirements, and has a wide market prospect.

[0043] The weft backing weft yarn 10, the first oblique backing weft yarn 20 and the second oblique backing weft yarn 30 at least contain TPEE monofilament or composite monofilament containing TPEE monofilament. The TPEE (thermoplastic polyester elastomer) monofilament is a single continuous filament made of TPEE material. TPEE is a material that combines the elasticity of rubber and the processing characteristics of thermoplastic plastic, with good mechanical properties, high elasticity and wear resistance. The composite yarn containing TPEE monofilament is a yarn formed by mixing or compounding TPEE monofilament with other fibers or materials (such as polyester, nylon, cotton, etc.). This composite yarn combines the excellent properties of TPEE and the properties of other materials, widening its application range. The weft yarn uses TPEE monofilament or composite yarn containing TPEE monofilament, which has excellent elasticity and flexibility, wear resistance, chemical resistance and weather resistance, and is easy to process, can enhance the stability of the fabric, has good processing performance, and the weft backing weft yarn 10, the first oblique backing weft yarn 20 and the second oblique backing weft yarn 30 use TPEE monofilament or composite monofilament containing TPEE monofilament, which can significantly improve the elasticity, wear resistance, chemical resistance and overall performance of the fabric, and is suitable for a variety of high-performance and special-purpose fabrics.
