(1) The position of the rear beam (C28) is too low. After opening, the tension difference between the upper and lower warp yarns is too small. When the weft yarn shrinks, the warp yarns are not easy to move horizontally with the weft yarns, so the gaps in the reed teeth after weft cannot be filled, forming a square eye on the cloth. The warp yarns on both sides differ, and the thicker cloth surface on the one side is affected, resulting in square eyes.
(3) The warp holder is too close to the weaving opening. This increases the tension of the pressing mouth, affecting the warp yarns not easily swim and move, resulting in square eyes.
(4) The hanging collar is too high or the side strut (L44) is too low. Both cases will reduce the tension difference between the upper and lower layers of warp yarns. The cloth surface is prone to full width and edge square eyes.
(5) The hanging sling is too tight, which makes it difficult for the warp yarn to move in the hentai eyes when weaving. When weaving, the warp yarn tension in the weft area cannot be compensated, the warp yarn dry is damaged, and the fabric is The surface is thin and not plump, and severely it forms square eyes.
(6) The iron stalk of the healing wire is bent, causing the healing wires on the same water trunk line to produce square eyes.
(7) The healing clip at the lower end of the healing frame is damaged or lost, so that the lower warp yarn is away from the shuttle plate.
(8) The tension of the warp yarn is too large, which means that the tension difference between the upper and lower layers of warp yarns is greatly reduced.
(9) In the starting combination, the brake roulette (F216) does not come into close contact with each other, and the gap slip occurs during weaving, which means that the resistance is large when weaving. The slip increases, weakens the weft force, and makes the fabric surface less square eyes.
(10) The opening time is inappropriate. The door is opened early, and the angle between the warp yarns and the weft yarns is relatively large. After weaving, the weft yarns are not easy to reverse and backward. The fabric surface is plump and thick. The opening time is late, the tension of the warp yarn is small, and the tension is also small when weaving. If some warp yarns are too loose, the fabric surface will be uneven. In addition, due to the late opening, the tension difference between the upper and lower layers of warp yarns is small. The upper warp yarn is not easy to move sideways, so square eyes will appear on the cloth surface.
(22) The contact position of the stopper hitting the mouth (K23, K27) is not up to standard, the clamping shaft hook foot (K26) fails or the reel is loose, causing the steel bar to be subjected to the reaction force on the fabric when weaving, and then the reel is allowed to cause the steel bar to be wefted. , the weft yarn cannot reach the specified position, causing square eyes.
