Color Wing Difference

Color Wing Difference

In the textile sector, the fact that the right and left sides of the woven fabrics are in different color tones is called color wing difference and is a serious problem. However, this problem is generally not easy to recognize before the fabric is cut. This is understandable after the fabric has been cut into a garment. The color flap problem is a quality problem in dyeing yarns or woven fabrics.

The difference between right and left or wing is the difference in color from the edge of the fabric to the edge. This is caused by curvature of the clamping rollers. Because of the curvature, the edges of the clamping roller are less tightened. As such, a greater amount of dyestuff remains in the middle and edges of the fabric. The color differs between the edges because the spin function is not evenly performed.

Sometimes there is a temperature difference between the edges and the middle of the fabric in the dyeing process, and the fabric is not properly wound on the rollers. Therefore, color differences may occur from the edges of a dyed fabric towards the center.

For physical tests performed in accredited laboratories, standards issued by local and foreign organizations are complied with. In this context, the following standards are used in color wing difference analysis:

  • TS EN ISO 105-J03 Textiles - Color fastness tests - Part J03: Calculation of color differences
  • AATCC 173 Calculation of small color differences for acceptability (Test method 173)
  • AATCC EP9 Visual evaluation of textile color differences

These test methods describe general principles and processes for identifying and identifying test samples. The visual color difference assessments of textile products are connected to a standard.

All laboratories must use state-of-the-art equipment and equipment in order to produce fast, high quality and reliable results. It is also important to have a strong technological infrastructure and an experienced and trained staff.
