Yellowing tendency of ozonated cotton fabric and ways to prevent this undesirable side effect

Abstract

This paper provides a general framework for studying the yellowing tendency of ozonated cotton fabric. Yellowing tendency of ozonated cotton fabric and ways to prevent this situation was examined extensively. For this purpose, five different treatments (hot/cold rinsing, washing, reductive washing, catalase treatment) were performed after ozonation. It was found that performing any kind of treatment was significantly important for preventing yellowing of ozonated cotton fabric during storage.

Keywords:

• ozone
• yellowing
• cotton fabric
• whiteness
• bleaching

Notes

∗The temperature was raised from 50°C to 85°C after treatment and pegged for 10 min.

∗∗Neutralization was performed.

^a After all treatments, samples were dried at 80°C.
