1. Reasons for uneven mesh.
(1) The height of the two ends of the suspension is inconsistent, causing the net to roll in the high end and roll back in the low end, resulting in unevenness in the middle of the net.
(2) Insufficient tension of the net and the appearance of broken weft.
(3) When weaving plain weave mesh, silk with a serious ovality enters the mesh.
(4) When weaving plain weave mesh, if the warp position line coincides with the warp straight line (that is, when the reed is flat, the warp eye coincides with the warp straight line), the woven mesh will be uneven. During carding, the position of the twisting bar vibrates up and down, causing the relative position of the warp to be high or low (even if it is a small change), resulting in the curved diameters woven on the mesh unable to be on the same plane, resulting in uneven mesh.
(5) Uneven mesh occurs during the process of feeding the warp during weft-beating.
(6) When the mesh roller is not flexible, the tension of the net changes alternately, causing uneven mesh.
2. Solutions for preventing uneven mesh surface:
(1) Maintain moderate and consistent warp tension during weaving.
(2) Use a low or high density weaving technique.
(3) Do not feed any warp while weft-beating.
(4) Avoid using wire with excessive ellipticity.
