Description

Knitting fabric and knitting method thereof, vamp and footwear product Technical Field The application relates to the technical field of textiles, in particular to a braided fabric, a braiding method thereof, a vamp and a footwear product. Background The fly knitting technology has become one of the currently mainstream vamp manufacturing technologies by virtue of the characteristics of integrated knitting and forming, light weight, excellent air permeability and the like. In the structural design of the fly-knitted vamp, in order to meet the functional requirements of different parts, a combined structure of a single-layer area and a double-layer area is generally adopted, wherein the single-layer area is mainly realized by single-needle bed knitting, is mainly used for ventilation and light weight and is usually used for parts needing a large amount of heat dissipation such as the middle part of the vamp, and the double-layer area is formed by double-needle bed knitting, has higher structural strength and supporting performance and is usually used for parts needing anti-collision, supporting or attaching functions such as a toe cap, a heel and an arch. However, the existing fly-weaving process has significant technical drawbacks in achieving the transition between the single layer region and the double layer region. Because single-layer knitting only uses a single needle bed for operation, double-layer knitting needs the cooperation of double needle beds to participate, and the two structures have larger differences in the number of knitting needles, yarn loop density and yarn tension. When single-layer and double-layer switching is performed in the knitting process, obvious zigzag lines are generated in the joint area due to discontinuous needle movement, abrupt yarn supply and low matching degree of the coil structure. The texture not only damages the visual flatness and the whole aesthetic degree of the vamp surface, influences the texture of the product, but also leads to the reduction of the fitting degree of the foot and the vamp due to uneven joint in the actual wearing process, is easy to generate local friction and uncomfortable feeling, and reduces the comfort and the functional performance of the shoe. Disclosure of Invention In order to solve one or more of the above technical problems in the prior art, the application provides a braided fabric, a braiding method thereof, a vamp and a footwear product, so as to solve the problems of obvious saw teeth, poor fitting degree and the like in a single-layer and double-layer connecting area in the prior art. In order to achieve the above purpose, the technical scheme adopted by the application for solving the technical problems is as follows: In a first aspect, the present application provides a braid comprising a first region 100, a second region 200, and a transition structure 300 formed at the junction of the first region 100 and the second region 200, the number of braiding layers of the second region 200 being greater than the number of braiding layers of the first region 100; The transition structure 300 includes a loop transition portion 310 extending from the second region 200 toward the first region 100, and a reverse wrap edge portion 320 between the loop transition portion 310 and the second region 200. According to the technical scheme, the composite transition structure formed by the loop transfer transition part and the reverse wrapping edge part is arranged at the joint of the first area and the second area, so that the technical problem that the joint is obvious in saw tooth feel in the existing fly weaving process is successfully solved, smooth transition between the first area and the second area is realized, the attractiveness and the texture are remarkably improved, the wearing comfort and the fitting performance are enhanced, the structural integrity is optimized, and the mechanical property is enhanced. In a specific embodiment, the loop-transfer transition 310 is formed by at least one coil of the second region 200 being offset in the direction of the second region 200 by a loop-transfer operation. According to the scheme, the loop of the second area 200 is shifted to the direction of the second area 200 to form the loop transferring transition part 310, so that the self-adaptive buffering and rebalancing of yarn tension are realized, the sawtooth cause is basically weakened, a physical slope with a progressive structure for dismissing is constructed, the visual and tactile flatness is improved, the structure anchoring effect of the transition area is enhanced, and the durability is improved. In a specific embodiment, the loop-transfer transition 310 has a loop-transfer offset distance of at least 1 needle position. According to the scheme, the transfer offset distance of the transfer transition part 310 is limited to at least 1 needle position, so that the optimal balance of tension buffering and structural continuity is reali
