Embodiment 3

(18) Referring to FIGS. 5, 6, and 7, this embodiment provides a fabric comprising a body region 14 and a mesh region, wherein the mesh region is provided with a mesh weave.

Embodiment 4

(19) In this embodiment, the number of first heddled warp yarns 10 is three, and the number of second heddled warp yarns 11 is three.

(20) Referring to FIGS. 9 and 10, this embodiment provides a method for weaving fabric utilizing a weaving machine with the shedding mechanism structure 19. The method comprises the following steps:

(21) Weaving of the body region 14: under the condition that the first heddled warp yarn 10 and the second heddled warp yarn 11 do not interfere with each other, the ground shedding frame 18 drives the first heddled warp yarn 10 to form a shed for inserting the weft yarn 16, while the shedding mechanism structure 19 drives the second heddled warp yarn 11 to form a shed for inserting the weft yarn 16, thereby interlacing to form the fabric body region 14;

(22) Weaving of the mesh region: Three of the first heddled warp yarns 10 are selected as the first unit warp bundle, such that the second heddled warp yarn 11 and the first unit warp bundle form a shed for inserting the weft yarn 16. The Jacquard part and the reset part drive the shedding mechanism structure 19 to adjust the relative positions of the first heddled warp yarn 10 and the second heddled warp yarn 11, thereby ensuring that the horizontal elevations of the first heddled warp yarn 10 and the second heddled warp yarn 11 differ and do not interfere with each other. The Jacquard part and the reset part drive the front base shedding frame 4 of the shedding mechanism structure 19 to raise and the rear base shedding frame 5 to fall, thereby closing the heddle eye 6 and gathering the three second heddled warp yarns 11 within the heddle eye 6 into a second unit warp bundle. Simultaneously, the first heddled warp yarn 10 raises along the edge of the half shedding frame 17 with the front base shedding frame 4 and ultimately slides between the rear base shedding frame 5 and the half shedding frame 17, such that the second unit warp bundle is entwined with the weft yarn 16 on the first unit warp bundle to form a mesh weave.

(23) During the weaving process, the front base shedding frame 4 and the rear base shedding frame 5 of the shedding mechanism structure 19 are controlled to rise or fall by means of the Jacquard part hole, thereby controlling the opening and closing of the heddle eye 6. The first heddled warp yarn 10 passes through the warp guide hole on the ground shedding frame 18 and the heddle eye 6 on the shedding mechanism structure 19, respectively. The second heddled warp yarn 11 passes through the warp guide hole of the ground shedding frame 18 and subsequently between the front base shedding frame 4 and the rear base shedding frame 5 of the shedding mechanism structure 19. The weaving body region 14 process specifically entails adjusting the relative positions of the first heddled warp yarn 10 and the second heddled warp yarn 11 via the ground shedding frame 18, thereby ensuring that the horizontal elevations of the first heddled warp yarn 10 and the second heddled warp yarn 11 are distinct and mutually non-interfering. Furthermore, the Jacquard part and reset part drive the ground shedding frame 18 to rise or fall, causing the first heddled warp yarn 10 to move synchronously with the ground shedding frame 18 to form a shed for the introduction of the weft yarn 16.

(24) During the process of weaving the body region 14, the shedding mechanism structure 19 is derived by the Jacquard part and the reset part to lower the front base shedding frame 4 and raise the rear base shedding frame 5, thereby opening the heddle eye 6. At this stage, the three second heddled warp yarns 11 within the heddle eye 6 are in a dispersed, freely movable state, allowing each second heddled warp yarn 11 to be individually manipulated by the ground shedding frame 18 to form a Jacquard weave.

(25) In this embodiment, the second heddled warp yarn 11 within the heddle eye 6 slides vertically inside the heddle eye 6 as the front base shedding frame 4 moves up and down. The first heddled warp yarn 10, located outside the heddle eye 6, slides vertically between the front base shedding frame 4 and the half shedding frame 17 as the front base shedding frame 4 falls. When the front base shedding frame 4 reaches its uppermost position, the first heddled warp yarn 10 slides along the edge of the half shedding frame 17 to the space between the rear base shedding frame 5 and the half shedding frame 17, as shown in FIG. 9.

(26) During the weaving process, the present application enables independent raising or lowering of the front and rear base shedding frames 5 of the shedding mechanism structure 19 via the Jacquard part and the reset part, thereby controlling the opening and closing of the heddle eye 6. The configuration of the heddled warp yarn within the heddle eye 6 can be adjusted according to actual weaving requirements, allowing the resulting fabric to exhibit a greater diversity of structural patterns and enhancing the fabric's sense of layering.

(27) The present application configures the shedding mechanism structure 19 with three independent movable parts, thereby enabling, during the weaving process, the opening and closing of the heddle eye 6 to be controlled by the movement of the front and rear base shedding frames 5. This allows the heddled warp yarn within the heddle eye 6 to be gathered or dispersed. The heddle eye 6 can accommodate two or more heddled warp yarns, and, through the vertical movement of multiple ground shedding frames 18, a shed for inserting the weft yarn 16 can be formed, thereby enabling the weaving of multiple fabric patterns within a single shedding group.

(28) The foregoing are merely preferred Embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be encompassed within the scope of protection of the present application.
