Description

Technical Field

[0001] This utility model relates to the field of footwear manufacturing technology, specifically to a dynamic two-color paddle flyknit upper. Background Technology

[0002] Existing flyknit uppers have limitations in terms of visual dynamic effects. Most flyknit uppers offer static patterns, while a few achieve limited dynamic effects through mesh variations or single-material deformation, but these effects are often not pronounced enough or lack a sense of three-dimensionality. As consumer demand for personalized products and interactive experiences grows, developing products with significant dynamic visual effects becomes particularly important.

[0003] In existing technologies, some products attempt to achieve dynamic effects by adding external decorative elements or using special materials, but these methods often increase weight, affect breathability, or increase manufacturing costs. Other designs employ simple color variations but lack a sense of depth and multi-layered visual impact. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing flyknit shoe uppers having a monotonous, unclear, and three-dimensional dynamic visual effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dynamic two-color flyknit upper includes a main body woven from flyknit yarns. The main body comprises a bottom layer and a top layer. The bottom layer is a mesh structure layer woven from first-color yarns. The top layer consists of several flyknit units, each formed by alternating weaves of second-color and third-color yarns. When the main body is stretched, the flyknit units reversibly deflect from a first stable position to a second stable position, while the mesh of the mesh structure layer undergoes coordinated deformation. The visual exposure ratio of the first-color, second-color, and third-color yarns dynamically changes with the deflection of the flyknit units and the deformation of the mesh.

[0006] A further improvement is that the mesh structure layer is a rhomboid mesh structure layer, a hexagonal mesh structure layer, or a wavy mesh structure layer, and the mesh structure layer changes its opening area through yarn slippage when dynamically stressed.

[0007] A further improvement is that the first colored yarn is either white elastic breathable yarn or black elastic breathable yarn.

[0008] A further improvement is that the second and third color yarns are elastic yarns with complementary colors or high-contrast color combinations.

[0009] A further improvement is that the paddle unit is woven into the bottom layer by an elastic cantilever braided connection structure, the length and stiffness of which are configured to allow the paddle unit to warp under stress.

[0010] A further improvement is that the elastic cantilever braided connection structure is woven from elastic yarn, and the elastic modulus of the elastic cantilever braided connection structure is lower than the elastic modulus of the paddle unit.

[0011] A further improvement is that the paddle unit is coplanar with the bottom layer when static, and forms an angle of 10°-60° with the bottom layer when dynamic.

[0012] A further improvement is that the arrangement direction of the paddle units on the upper body forms an angle with the expected stretching direction.

[0013] Compared with existing technologies, the above technical solution has the following advantages: The surface-layered paddle units and the underlying planar mesh structure work together to respond to external forces, producing multi-layered and multi-dimensional visual changes. Each paddle unit contains two contrasting colors, which change due to angle and light reflection when deflected, creating a distinct color alternation effect. The paddle units are connected to the underlying weave structure by elastic cantilever weave, ensuring controllable and reversible deflection behavior under force. The force-induced deflection of the paddle units creates dynamic shadows and three-dimensional effects, forming a complex visual interaction with the color changes of the underlying mesh. Significant dynamic visual effects: The visual changes produced by the coordinated deformation of the two-layer structure are more obvious and complex than those of a single structure; Rich three-dimensionality: The warping motion of the paddle unit creates a three-dimensional dynamic effect that cannot be achieved with traditional flat fabrics; Enhanced product interactivity: Visual changes are directly related to the intensity and manner of the wearer's movement, creating a highly personalized interactive experience; Integrated structure: All functions are formed in one piece through a flyknit process, without the need for additional assembly, maintaining the lightweight and breathable properties of the fabric.

[0017] See Figures 1-6 As shown, the technical solution adopted in this specific embodiment is: a dynamic two-color swivel flyknit upper, comprising an upper body 1 woven integrally with flyknit, characterized in that: the upper body 1 includes a bottom layer 2 and a top layer 3, the bottom layer 2 is a mesh structure layer woven with first-color yarn, the top layer 3 is composed of a plurality of swivel units 4, the swivel units 4 are woven alternately with second-color yarn and third-color yarn, the swivel units 4 reversibly deflect from a first stable position to a second stable position when the upper body 1 is stretched, and at the same time the mesh of the mesh structure layer undergoes coordinated deformation; the visual exposure ratio of the first-color yarn, the second-color yarn and the third-color yarn dynamically changes with the deflection of the swivel units 4 and the deformation of the mesh.

[0018] The mesh structure layer is a rhomboid mesh structure layer, a hexagonal mesh structure layer, or a wavy mesh structure layer. When the mesh structure layer is dynamically stressed, the opening area changes due to the slippage of the yarn.

[0019] The first colored yarn is either white elastic breathable yarn or black elastic breathable yarn.

[0020] The second and third colored yarns are elastic yarns that are complementary colors or combinations of high-contrast colors. A strong contrast can be created using bright yellow and dark blue.

[0021] The paddle unit 4 is woven onto the bottom layer 2 via an elastic cantilever braided connection structure. The length and stiffness of the elastic cantilever braided connection structure are configured to allow the paddle unit 4 to warp under stress.

[0022] The elastic cantilever braided connection structure is made of elastic yarn, and the elastic modulus of the elastic cantilever braided connection structure is lower than the elastic modulus of the paddle unit 4.

[0023] In this configuration, the paddle unit 4 is coplanar with the bottom layer 2 when static, and forms an angle of 10°-60° with the bottom layer 2 when dynamic.

[0024] The arrangement direction of the paddle units 4 on the upper body 1 forms an angle with the expected stretching direction. In practical applications, the arrangement direction and density of the paddle units 4 can be optimized according to the expected motion deformation characteristics of different areas of the upper. For example, in the metatarsophalangeal joint area, the paddles can be arranged longitudinally to produce the maximum deflection effect during walking flexion.

[0025] The working principle of this utility model is as follows: the main body of the shoe upper is integrally formed by advanced flyknit programming technology, and the bottom layer is woven with the first color yarn (such as black or white) to form a basic mesh structure. These meshes are preferably rhomboid, hexagonal or wavy, and the weaving process enables them to undergo controllable shape changes when subjected to force. The outer layer consists of multiple independent flap units. Each flap unit is woven into the bottom layer by a connecting structure made of elastic yarn. The elastic modulus of the connecting structure is lower than that of the flap unit to ensure that the flap unit can produce the expected warping angle when the fabric is stretched in a specific direction. The pick unit itself is formed by alternating weaves of second-color yarn and third-color yarn to create distinct two-color segments. When static, the pick lies flat on the same plane as the bottom layer, mainly displaying the color facing outwards. When subjected to force, the exposed area of ​​different colors changes with the angle, and the brightness and saturation of the colors also change due to the change in the angle of light reflection. The deformation of the bottom mesh and the deformation of the paddle are designed in synergy. When the main body of the shoe upper is stretched, the shape of the bottom mesh changes, which causes the area of ​​the bottom color to change. This, combined with the color change of the paddle, produces a complex visual mixing effect.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model.
