[0030] Referring to FIG. 1, the utility model provides a kind of multi-axial shoe material fabric, it includes weft yarn 10, first oblique weft yarn 20, second oblique weft yarn 30 and ground yarn 40, the weft yarn 10 is padded in weft direction;First oblique weft yarn 20 is padded in one side of weft weft yarn 10, and forms angle with weft weft yarn 10;Second oblique weft yarn 30 is padded in the other side of weft weft yarn 10, and forms angle with weft weft yarn 10;The ground yarn 40 is radially chain into loop;The weft yarn 10, first oblique weft yarn 20, second oblique weft yarn 30 and ground yarn 40 are thermoplastic polyurethane elastomer filament yarn or composite yarn comprising thermoplastic polyurethane elastomer filament yarn.

[0031] The warp direction is taken as 0° as a reference, i.e. the weft yarn 10 is padded in a 90° direction, the first oblique weft yarn 20 is padded in a 0°-90° direction, the second oblique weft yarn 30 is padded in a 0°--90° direction, and the ground yarn 40 is chained in a 0° direction.

[0032] The weft yarn 10, the first oblique weft yarn 20, the second oblique weft yarn 30 and the ground yarn 40 are made of thermoplastic polyurethane elastic filaments or composite yarns containing thermoplastic polyurethane elastic filaments, which have good wear resistance, bending resistance, tear resistance and other properties. The multi-axial padding and multi-axial weaving of the shoe material fabric have good deformation resistance, such as stretching, twisting and tearing, and can strengthen the extensibility and strength of the shoe material fabric, and meet the requirements of good strength, wear resistance, bending resistance and other properties of the shoe material fabric.

[0033] Preferably, the first oblique weft yarn 20 and the weft yarn 10 form an included angle of 30°-60°, i.e. the first oblique weft yarn 20 is padded in a 30°-60° direction; the second oblique weft yarn 30 and the weft yarn 10 form an included angle of 30°-60°, i.e. the second oblique weft yarn 30 is padded in a -30°--60° direction.

Of course, the above technical solution can also include a warp weft yarn, which is padded in a 0° direction, i.e. forms an included angle of 90° with the weft yarn 10.

[0034] Preferably, the weft yarn 10, the first oblique weft yarn 20 and the second oblique weft yarn 30 form adhesive points at the intersections. The adhesive points formed by the weft yarn 10, the first oblique weft yarn 20 and the second oblique weft yarn 30 at the intersections can increase the stability and structural strength of the shoe material fabric, reduce the deformation and loosening of the shoe material fabric, and make the shoe material fabric more firm and durable. The specific implementation can be that the woven fabric is sent into a process in which the temperature is greater than the melting point of the yarn or the yarn skin of the weft yarn 10, the first oblique weft yarn 20 and the second oblique weft yarn 30, so that the fibers of the weft yarn 10, the first oblique weft yarn 20 and the second oblique weft yarn 30 are fused together to form adhesive points at the intersections of the yarns, which can help to improve the dimensional stability of the shoe material fabric and reduce the deformation. The process can be the original process, such as dry heat setting or wet heat setting in the dyeing and finishing process, or a newly added process.

[0035] The ground yarn 40 has at least one feature different from the weft backing yarn 10, the first diagonal backing yarn 20 and the second diagonal backing yarn 30; the feature includes elongation, the elongation of the ground yarn 40 is greater than the weft backing yarn 10, the first diagonal backing yarn 20 and the second diagonal backing yarn 30.

The ground yarn 40 can be a composite yarn of a sheath-core structure thermoplastic polyurethane elastomer filament, the sheath layer is a thermoplastic polyurethane elastomer filament, and the core layer is a chemical fiber; the chemical fiber is a non-elastic fiber such as polyester and nylon, which forms a sheath-core structure with the thermoplastic polyurethane elastomer filament, so that the ground yarn 40 has good elongation, and the shoe material fabric formed by weaving has good longitudinal elongation.

[0036] The weft backing yarn 10, the first diagonal backing yarn 20 and the second diagonal backing yarn 30 can have the same feature, or at least one different feature, which can be breaking strength. That is, the weft backing yarn 10 has at least one feature different from the first diagonal backing yarn 20 and the second diagonal backing yarn 30; the feature includes breaking strength. That is, the thermoplastic polyurethane elastomer filament yarn or the composite yarn containing the thermoplastic polyurethane elastomer filament yarn is used to give the shoe material fabric transverse or diagonal strength and support, so that the weft backing yarn 10 or the first diagonal backing yarn 20 and the second diagonal backing yarn 30 have higher breaking strength, which can enhance the transverse or diagonal tensile performance of the shoe material fabric, making the shoe material fabric more tough and durable; in some embodiments, the breaking strength of the first diagonal backing yarn 20 and the second diagonal backing yarn 30 is greater than that of the weft backing yarn 10, which enhances the transverse strength and support of the shoe material fabric; in some embodiments, the breaking strength of the weft backing yarn 10 is greater than that of the first diagonal backing yarn 20 and the second diagonal backing yarn 30, which enhances the two diagonal strengths and supports of the shoe material fabric; the thermoplastic polyurethane elastomer filament yarn or the composite yarn containing the thermoplastic polyurethane elastomer filament yarn with different breaking strengths can be used to meet different shoe material fabric design and manufacturing requirements, and increase the adaptability of the shoe material fabric. The ground yarn 40 with different breaking strengths can be selected according to specific needs to realize the change of the structure and effect of the shoe material fabric, and meet the needs of different markets and consumers.

[0039] Denier is a unit of measure for the linear density of textile fibers, and the larger the value, the thicker the fiber line and the higher the strength and wear resistance. Preferably, the ground yarn 40 has a tenacity of at least 600 grams per denier of thermoplastic polyurethane elastomer filament as a chain material, which has better tensile strength and can increase the strength and wear resistance of the shoe material fabric. The ground yarn 40 can provide better support and structural stability for the weft base weft yarn 10, the first diagonal base weft yarn 20 and the second diagonal base weft yarn 30, reduce the deformation and looseness of the shoe material fabric, and help to increase the stability and structural strength of the shoe material fabric.

[0040] Breaking strength represents the force (strength) that the fiber or yarn withstands at break per unit of density (D) in cN, which is centinewton, a unit of force in the International System of Units, equal to 0.01 newton. Thus, a breaking strength of 1.5 cN / D means that the fiber or yarn withstands a force greater than 1.5 centinewtons per unit of density at break. Preferably, the yarn 40 has a breaking strength greater than 1.5 cN / D, which as a warp material can increase the overall strength of the footwear material, making it more resistant to stretching under external forces and to friction and abrasion in daily use, prolonging the life of the footwear material, while providing better support and structural stability to the footwear material, helping to increase the stability and structural strength of the footwear material.

[0041] Similarly, the weft backing weft yarn 10 has a tenacity of at least 100 grams per denier; and / or the weft backing weft yarn 10 has a breaking strength of at least 1.2 CN / D. It is understood that in some embodiments the weft backing weft yarn 10 has a tenacity of at least 100 grams per denier; in some embodiments the weft backing weft yarn 10 has a breaking strength greater than 1.2 cN / D; in some embodiments the weft backing weft yarn 10 has a tenacity of at least 600 grams per denier and a breaking strength greater than 1.2 cN / D. Preferably, the weft backing weft yarn 10 has a breaking strength greater than 1.2 cN / D, which as a weft material can increase the overall strength of the footwear material, making it more resistant to stretching under external forces and to friction and abrasion in daily use, prolonging the life of the footwear material, while providing better support and structural stability to the footwear material, helping to increase the stability and structural strength of the footwear material. Preferably, the weft backing weft yarn 10 has a breaking strength greater than 1.2 cN / D, which as a weft material can increase the overall strength of the footwear material, making it more resistant to stretching under external forces and to friction and abrasion in daily use, prolonging the life of the footwear material.

[0042] Similarly, the first and second diagonal weft yarns 20 and 30 have a tenacity of at least 150 grams per denier; and / or the first and second diagonal weft yarns 20 and 30 have a breaking strength of at least 2 cN / D. It can be understood that in some embodiments, the first and second diagonal weft yarns 20 and 30 have a tenacity of at least 150 grams per denier; in some embodiments, the first and second diagonal weft yarns 20 and 30 have a breaking strength of greater than 1.2 cN / D; in some embodiments, the first and second diagonal weft yarns 20 and 30 have a tenacity of at least 600 grams per denier and a breaking strength of greater than 1.2 cN / D. Preferably, the first and second diagonal weft yarns 20 and 30 have a breaking strength of greater than 1.2 cN / D, so that they have better tensile strength, which can increase the strength and wear resistance of the shoe material fabric. The first and second diagonal weft yarns 20 and 30 can provide good support and structural stability in two diagonals (at an angle with the weft direction), increase the tenacity of the diagonals, and help to increase the stability and structural strength of the shoe material fabric. Preferably, the first and second diagonal weft yarns 20 and 30 have a breaking strength of greater than 1.2 cN / D, which can increase the overall strength of the shoe material fabric as a diagonal material, so that it can better withstand external stretching and resist friction and wear in daily use, prolonging the service life of the shoe material fabric.

The ground yarn 40 is padded in a full-thread manner to form a chain, so that the fabric has good longitudinal extensibility, increases the elasticity and resilience of the shoe material fabric, and makes the shoe material fabric have better supportability and shape recovery ability, better fits and supports the instep to adapt to the movement of the foot, and provides a more comfortable wearing experience.
