      Why does the fabric crease during the dyeing process?
      Mar 05, 2020

      Because the air dyeing machine is relatively fast in cloth speed, its main purpose is to effectively increase the exchange frequency between the fabric and the dyeing solution, ensure the uniformity of the entire dyeing, and reduce the stagnation of the fabric under static conditions. Time, effectively avoiding the phenomenon of creases in the fabric. However, many relatively thin and high-density filament fabrics are very prone to abrasion if the cloth speed is fast, but if the cloth speed is If it is slow, creases will appear, so we should choose an appropriate cloth speed to reduce the occurrence of such situations.

      If the knitted fabric has creases, the main reason is that during the weaving process of the knitted fabric, a relatively large internal stress occurs, and the external radial tension is relatively large, it will be very easy to occur radial folds Marks, and are basically in the presence of water during processing, so in the entire dyeing process, the dye will be different in the location of the creases, there are obvious marks of varying depth, want to avoid or reduce this type of When the situation occurs, we should match the air volume passing through the line speed of the cloth lifting roller in the early processing, so that even if the fabric leaves the cloth guide tube, it still has an expansion process, which can continuously Adjust the position so that the crease position can be quickly expanded.
