What of Polyester weather marks?

Generally refers to a dyeing defect produced during the drying and storage of textiles after printing and dyeing.

Compared with the normal dyed light blank, the wind seal will show a white or dark gray stripe in the latitude direction of almost the entire door. The defect cannot be seen before the setting, and it will occur after the setting.

Polyester fabrics are not easy to produce wind marks during continuous production (long car production lines), while intermittent production (when high temperature and high pressure overflow dyeing) is prone to produce wind marks.

Most of the wind marks of polyester fabrics are produced after the cloth is dehydrated and opened, and before the final setting, and appear in the reciprocating folding marks when the cloth stacker is stored. In severe cases, dozens of them will appear in the weft direction, and their spacing is exactly the spacing of the reciprocating folding of the grey fabric.
