[0028] Please refer to Fig. 9 as well as Fig.10 This embodiment provides a fabric weaving method, which uses a loom having a tangle heddle structure 17 as described above, and the method includes the following process: Weaving body area 14: In a state where the first twisted warp 10 and the second twisted warp 11 do not interfere with each other, the first twisted warp 10 is driven by the ground heddle 18 to form a shed for introducing the weft yarn 16, and the second twisted warp 11 is driven by the twisted heddle structure 17 to form a shed for introducing the weft yarn 16, and the fabric body area 14 is interwoven; Weaving mesh area: the three first twisted warps 10 are selected as the first unit warp bundle, and the second twisted warp 11 and the first unit warp bundle form a shed for introducing the weft yarn 16, and the relative positions of the first twisted warp 10 and the second twisted warp 11 are adjusted by the jacquard component and the reset component so that the horizontal heights of the first twisted warp 10 and the second twisted warp 11 are different and do not interfere with each other, and the front basic heddle 4 of the twisted heddle structure 17 is driven to rise and the rear basic heddle 5 is driven to descend by the jacquard component and the reset component, and the heddle eye 6 is closed and the three second twisted warps 11 in the heddle eye 6 are gathered into the second unit warp bundle. At the same time, the first twisted warp 10 slides upward along the edge of the half heddle 19 with the front basic heddle 4 and finally slides to between the rear basic heddle 5 and the half heddle 19, so that the second unit warp bundle cooperates with the weft yarn 16 to be twisted around the first unit warp bundle to form a mesh structure.

[0029] The front basic heddle 4 and the rear basic heddle 5 of the heddle structure 17 are controlled to rise or fall through the holes of the jacquard component during the weaving process to control the opening and closing of the heddle eye 6. The first warp 10 passes through the guide holes on the ground heddle 18 and the heddle eye 6 on the heddle structure 17 respectively. The second warp 11 passes through the guide holes of the ground heddle 18 and then passes through between the front basic heddle 4 and the rear basic heddle 5 of the heddle structure 17. The weaving process of the main body area 14 is specifically to adjust the relative positions of the first warp 10 and the second warp 11 through the ground heddle 18 so that the horizontal heights of the first warp 10 and the second warp 11 are different and do not interfere with each other, and the ground heddle 18 is driven to rise or fall through the jacquard component and the reset component so that the first warp 10 forms a shed for introducing the weft yarn 16 together with the ground heddle 18.

[0030] During the weaving process of the main body area 14, the jacquard component and the reset component are used to control the front base heddle 4 of the heddle structure 17 to descend and the rear base heddle 5 to rise to open the heddle eye 6.

When the front basic heddle 4 rises to the uppermost position, the first warp 10 will slide along the edge of the half heddle 19 to between the rear basic heddle 5 and the half heddle 19. Fig. 9 shown.

[0032] During the weaving process, the present invention can control the front and rear base heddle 5 of the twisted heddle structure 17 to rise or fall independently through the jacquard component and the reset component, thereby controlling the opening and closing of the heddle eye 6. The shape of the twisted warp in the heddle eye 6 can be changed according to actual weaving needs, so that the woven fabric has more forms of organizational structure and enhances the layering of the fabric.

[0033] The present invention provides the twisted heddle structure 17 with three independent movable parts, so that during the weaving process, the opening and closing of the heddle eye 6 can be controlled by the interaction of the front and rear base heddle 5, so that the twisted warps in the heddle eye 6 can be gathered or dispersed, the heddle eye 6 can be passed through more than two twisted warps, and then a shed for weaving the weft yarn 16 can be formed by pulling up and down a plurality of ground heddle 18, thereby realizing the weaving of various tissue patterns of the twisted warps in one twist group.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
