[0030] See also Figure 1 As shown, the utility model provides a warp knitted multidimensional fabric, which includes a weft inlay yarn 10, a first oblique inlay weft yarn 20, a second oblique inlay weft yarn 30 and a ground yarn 40; the weft inlay weft yarn 10 is inlaid in the weft direction; the first oblique inlay weft yarn 20 is inlaid on one side of the weft inlay weft yarn 10 and forms an angle with the weft inlay weft yarn 10; the second oblique inlay weft yarn 30 is inlaid on the other side of the weft inlay weft yarn 10 and forms an angle with the weft inlay weft yarn 10; the ground yarn 40 is woven in the radial direction and is wrapped around the weft inlay weft yarn 10, the first oblique inlay weft yarn 20 and the second oblique inlay weft yarn 30 to form a warp plain structure.

[0031] Taking the warp direction 0° as a reference, that is, the first oblique weft yarn 20 is padded in the direction of 0° to 90°, and the second oblique weft yarn 30 is padded in the direction of 0° to -90°; the ground yarn 40 interweaves the weft weft yarn 10, the first oblique weft yarn 20 and the second oblique weft yarn 30 for continuous weaving, and the weaving shape is a warp plain structure. The weft weft yarn 10, the first oblique weft yarn 20 and the second oblique weft yarn 30 are inserted into the fabric from different directions to form three textile layers. At the same time, different hollow textures and appearances are formed by different numbers of empty passes of the weft weft yarn 10, the first oblique weft yarn 20 and the second oblique weft yarn 30, which can be adaptively adjusted according to actual production needs.

[0032] Warp weave is one of the basic weaves of warp knitted fabrics. Its characteristic is that the coils formed by the same warp yarn are alternately arranged in two adjacent coils. The coil form can be open or closed. Warp weave is woven by alternately padding yarns on two adjacent knitting needles for each warp yarn. There are two horizontal rows of coils in a complete weave. Because the yarn is bent at the connection between the coil stem and the extension line, the coil stem is tilted in the opposite direction of the extension line under the action of elastic recovery force, causing the longitudinal row of coils to be zigzag in the fabric. In addition, because the extension line passing through the loop presses one side of the coil column, the coil is turned to the plane perpendicular to the knitted fabric, so the appearance of the two sides of the grey fabric is similar. When a coil breaks and is stretched horizontally, the coils start to fall apart one by one along the longitudinal row in the opposite direction of weaving from the broken yarn, and the fabric is divided into two unconnected pieces. When the warp weave is stretched longitudinally or transversely, the fabric has a certain degree of extensibility due to the change of the inclination angle of the wire circle, the transfer of the yarn in the coil and the elongation of the yarn itself.

[0033] Preferably, the first oblique weft yarn 20 forms an angle of 45° to 60° with the weft weft yarn 10, that is, the yarn is padded in the direction of 45° to 60°; the second oblique weft yarn 30 forms an angle of -45° to -60° with the weft weft yarn 10, that is, the yarn is padded in the direction of -45° to -60°; the setting of this angle can prevent the comb from interfering with the movement of the padded yarn, and at the same time, the setting of this angle can make the weft yarn form a better supporting structure in the fabric, effectively enhance the tensile strength of the fabric, and prevent the fabric from being damaged or deformed due to external stretching. Of course, the above technical solution can also include warp weft yarns, which are padded in the direction of 0°, that is, forming an angle of 90° with the weft weft yarn 10.

[0034] The ground yarn 40 is woven in a full-threading manner, so that the fabric has good longitudinal extensibility and lateral extensibility. Full-threading means that the ground yarn 40 is inserted into each needle position during the weaving process, and a threading machine or a threading device is set to allow each yarn to accurately penetrate each needle position. According to the specifications of the chaining machine and the type of fabric to be produced, the parameters of the weaving equipment, including yarn tension, needle position spacing, etc., are adjusted. Start the chaining machine to ensure that the ground yarn 40 passes through each needle position smoothly to form a uniform and consistent weaving structure. The ground yarn 40 is woven in a full-threading manner, which can significantly enhance the overall strength and durability of the fabric, making it less likely to tear and wear. During the weaving process, each ground yarn 40 participates in the weaving, making the fabric structure more stable, less likely to deform and wrinkle, and the uniform yarn distribution makes the fabric surface smoother and smoother, thereby improving the aesthetics of the fabric.

[0035] The weft weft inlay yarn 10 , the first oblique weft inlay yarn 20 and the second oblique weft inlay yarn 30 have at least one characteristic different from the ground yarn 40 ; the characteristic includes elongation at break, and the elongation at break of the weft weft inlay yarn 10 , the first oblique weft inlay yarn 20 and the second oblique weft inlay yarn 30 is greater than that of the ground yarn 40 .

[0036] The lower elongation of the ground yarn 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, and improve the overall tensile strength and durability of the fabric. The larger elongation of the weft-inserted weft yarn 10, the first oblique weft-inserted weft yarn 20, and the second oblique weft-inserted weft yarn 30 enables them to better adapt to and disperse stress during fabric processing, thereby reducing the generation of wrinkles and curling, improving the surface flatness of the fabric, making the fabric softer and more elastic, improving the hand feel, enhancing the drape of the fabric, and making it more beautiful in appearance. The difference in elongation between the ground yarn 40 and the weft yarn can optimize the tension control during the weaving process, reduce the occurrence of yarn breakage and fabric defects, and improve production efficiency and yield rate.

[0037] The ground yarn 40 has at least one characteristic different from the weft weft yarn 10, the first bias weft yarn 20 and the second bias weft yarn 30; the characteristic includes breaking strength, and the breaking strength of the ground yarn 40 is greater than that of the weft weft yarn 10, the first bias weft yarn 20 and the second bias weft yarn 30.

[0038] In some embodiments, the breaking strength of the first oblique weft yarn 20 and the second oblique weft yarn 30 is greater than that of the weft weft yarn 10, thereby enhancing the lateral strength and support of the warp knitted multi-dimensional fabric; in some embodiments, the breaking strength of the weft weft yarn 10 is greater than that of the first oblique weft yarn 20 and the second oblique weft yarn 30, thereby enhancing the two oblique strengths and support of the warp knitted multi-dimensional fabric; ground yarns 40 with different breaking strengths can be selected according to specific needs to achieve changes in the structure and effect of the warp knitted multi-dimensional fabric and meet the needs of different markets and consumers.

[0039] In some embodiments, the weft inlay yarn 10, the first bias inlay yarn 20 and the second bias inlay yarn 30 have a breaking strength of at least 2.5 cN / D, and the ground yarn 40 has a breaking strength of at least 4 cN / D.

[0040] The breaking strength indicates the force (strength) that a fiber or yarn bears per unit density (D) when it breaks, and the unit cN represents centinewton, i.e. centinewton, which is a unit of force in the International System of Units and is equal to 0.01 Newton. Therefore, a breaking strength of 2.5 cN / D means that a fiber or yarn per unit density bears a force greater than 2.5 centinewton when it breaks. Preferably, the breaking strength of yarn 40 is not less than 4 cN / D. As a braiding material, it can increase the overall strength of the warp knitted multidimensional fabric, making it more able to withstand the stretching of external forces and resist friction and wear in daily use, extending the service life of the warp knitted multidimensional fabric, while providing better support and structural stability for the warp knitted multidimensional fabric, which helps to increase the stability and structural strength of the warp knitted multidimensional fabric. Similarly, it is preferred that the breaking strength of the weft inlay yarn 10, the first oblique inlay weft yarn 20 and the second oblique inlay weft yarn 30 is not less than 2.5 cN / D. The weft inlay weft yarn 10 can provide good support and structural stability in the weft direction, increase the toughness in the weft direction, and help increase the stability and structural strength of the warp knitted multidimensional fabric, so that it can better withstand the stretching of external forces and resist the friction and wear in daily use, and extend the service life of the warp knitted multidimensional fabric. The first oblique inlay weft yarn 20 and the second oblique inlay weft yarn 30 make it have better tensile strength, which can increase the strength and wear resistance of the warp knitted multidimensional fabric. The first oblique inlay weft yarn 20 and the second oblique inlay weft yarn 30 can provide good support and structural stability in two oblique directions (with the weft angle), increase the toughness in the oblique direction, and help increase the stability and structural strength of the warp knitted multidimensional fabric. As an oblique material, it can increase the overall strength of the warp knitted multidimensional fabric, so that it can better withstand the stretching of external forces and resist the friction and wear in daily use, and extend the service life of the warp knitted multidimensional fabric.

[0041] The ground yarn 40 at least contains polyester monofilament or composite monofilament containing polyester monofilament. 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 generally used in industry, clothing, home textiles and other fields. Composite yarn containing polyester monofilament is a yarn with multiple characteristics formed by mixing or compounding polyester monofilament with other fibers or materials (such as cotton, wool, nylon, etc.). This composite yarn combines the excellent properties of polyester with the properties of other materials to broaden its application range. The ground yarn 40 uses polyester monofilament or composite yarn containing polyester monofilament. Polyester monofilament has the advantages of high strength and durability, chemical corrosion resistance, low moisture absorption, dimensional stability, easy chemical processing, environmental protection, etc., which can significantly improve the performance and service life of the product, meet various application requirements, and have broad market prospects.

[0042] The weft-inlay weft yarn 10, the first oblique-inlay weft yarn 20 and the second oblique-inlay weft yarn 30 at least contain TPEE monofilament or composite monofilament containing TPEE monofilament. TPEE (thermoplastic polyester elastomer) monofilament is a single continuous filament made of TPEE material. TPEE is a material that has both the elasticity of rubber and the processing characteristics of thermoplastics. It has good mechanical properties and high elasticity and wear resistance. The composite yarn containing TPEE monofilament is a yarn that is formed by mixing or compounding TPEE monofilament with other fibers or materials (such as polyester, nylon, cotton, etc.) to form a yarn with multiple properties. This composite yarn combines the excellent properties of TPEE and the properties of other materials, broadening its scope of application. The weft yarn is made of TPEE monofilament or a composite monofilament containing TPEE monofilament. TPEE monofilament has excellent elasticity and flexibility, wear resistance, chemical resistance and weather resistance, etc. It is easy to process, can enhance the stability of the fabric, and has good processing performance. The weft inlay yarn 10, the first oblique inlay weft yarn 20 and the second oblique inlay weft yarn 30 are made of TPEE monofilament or a 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.
