The aim of the research was to study the effect of different types of softeners on whiteness value and yellowing propensity by curing conditions and on storage of 100% cotton woven fabric. Different ionic nature and compositions of softeners were applied from solution to the pretreated cotton samples singly and also in combination with optical brightening agent in pad-thermofixation process to investigate the reflectance variation due to different curing temperature and time. Yellowing of fabrics on storage were also predicted by phenolic yellowing test. Different ionic nature and composition of softeners influenced the reflectance and yellowing behavior differently due to various treatment conditions.

Keywords: Reflectance, yellowing propensity, softeners, optical brightener, curing.
