Colour Changes in Embroidery Threads from Chlorine Exposure
-
Cause of Discolouration: Often due to chlorine-based additives or spot removers in washing.
-
SULKY® Thread: Although highly resistant to heat, light, and perspiration, it is not chlorine-resistant—like all artificial silk threads.
-
Industry Standard: Chlorine additives are universally prohibited for viscose threads, indicated by a symbol on colour charts.
-
Chlorine Sensitivity: Discolouration varies by colour and chlorine concentration. Even partial discolouration of a design is possible.
-
Recommendation: For items exposed to heavy dirt or frequent washing (e.g. workwear), use POLY 40—a chlorine-resistant polyester thread.
