[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly influence the color and shape of clothing. Three-dimensional fabric is a personalized fabric, some of which are three-dimensional in feel, some are three-dimensional in vision, and some have both feel and three-dimensional appearance.

[0003] However, although existing fabrics have a variety of colors, their color fastness and strength are limited and they are easily damaged. Therefore, a new fabric design is needed to improve color fastness and strength. Utility Model Content

[0009] Preferably, the warp knitting coils of the connecting yarn and the base fabric are woven using a multi-axial warp knitting loop-forming device, and the multi-axial warp knitting loop-forming device includes a compound needle I, a compound needle II, a sinker and two comb bars.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By knitting warp-knitted coils of the base fabric with connecting yarns in a tricot stitch or a chain stitch, the connecting yarns of the multi-axial fabric have a high straightness. Each A area, B area, and C area are closely distributed but do not interweave with each other and are only fixed by the connecting yarns.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] A warp-knitted fabric with high color fastness, such as Figure 1-2As shown in the figure, it includes a multi-axial fabric. The multi-axial fabric includes warp binder yarns 3, weft binder yarns 4, bias yarns 5, connecting yarns 2 and base yarns. The base yarns are used to weave the base cloth 1 with a plain weave. The base cloth 1 is divided into area A, area B and area C. The warp binder yarns 3 are woven into area A of the base cloth 1 at an angle of 0°, the weft binder yarns 4 are woven into area B of the base cloth 1 at an angle of 90°, the bias yarns 5 are alternately woven into area C at an angle of ±0°. The connecting yarns 2 are woven with the base cloth 1 to form warp knitted loops in a warp plain stitch or chain stitch, and are woven with the warp binder yarns 3, weft binder yarns 4 and bias yarns 5; the warp binder yarns 3, weft binder yarns 4 and bias yarns 5 in area A, area B and area C do not interweave with each other, and they all interweave with the connecting yarns 2. The connecting yarns 2 of the multi-axial fabric are all in a straight state, and the straightness of the connecting yarns 2 of the multi-axial fabric is high. Each of area A, area B and area C is closely distributed but does not interweave and is only fixed by the connecting yarns 2. The utilization rate of the mechanical properties of the yarns of the fabric is high, the tensile strength in multiple directions is high, and the bias yarns 5 can inhibit the shear deformation of the fabric when resisting parallel shear forces and oblique external forces.

[0019] As Figure 3 shown, the base yarns of the warp binder yarns 3 and weft binder yarns 4 are alternately fed with yellow cotton roving and white cotton roving to weave the decorative yarn. An anti-color structure with two alternating yellow and white colors is formed on the core yarn of the decorative yarn. The two yellow and white cotton rovings are alternately distributed and woven into the outer wrap roving. After the warp binder yarns 3 and weft binder yarns 4 are woven, an appearance effect of alternating colors is formed on the multi-axial fabric. The decorative yarn is woven with an outer wrap roving by a three-roller fancy twisting machine. The core yarn of the three-roller fancy twisting machine passes through the yarn guide roller and enters the front roller. The yellow cotton roving and white cotton roving are used as the decorative yarn and pass through the back roller, middle roller and front roller in sequence. The white cotton roving enters the back roller at a constant speed to start weaving, and the yellow cotton roving is controlled to be alternately replaced. The two are output at the front roller to form a pattern, pass through the yarn guide hook, and then pass through the hollow spindle, and the pattern is fixed by the yarn fixing, and finally the compounded decorative yarn is output and wound onto the yarn tube. The wrapped yarn structure woven in this way is stable, reduces the wear of the yarn, and improves the overall color fastness of the multi-axial fabric.

[0020] As Figure 4 shown, the multi-axial warp knitting device is used for the connecting yarns 2 and the base cloth 1 to weave warp knitted loops. The multi-axial warp knitting device includes compound needles I 6, compound needles II 7, sinkers 8 and two guide bars 9. By means of a double-axial moving compound needle system, vertical direction piercing and looping are set, and horizontal direction reciprocating movement is set along with the advancement of the multi-axial fabric, so as to achieve the effect of reducing the large holes generated by the knitting needles blocking the advancement of the yarn layer after piercing.
