| dc.description.abstract | Reactive dyes cannot be stripped satisfactorily from cellulosic materials due to the formation of
co-valent bonds between dye and fiber. This research was under taken using around 5% bi-hetero
reactive dyes trichromatic combination on pretreated viscose fabric and stripping was carried out
in alkali reductive stripping process. The aim of the work was to investigate the effects of
reactive dye stripping on the quality of viscose fabric. Stripping performance was evaluated in
percentage by k/s analysis using spectrophotometer. Also Strength loss, weight loss, pilling
resistance, absorbency and color fastness of stripped fabric were calculated for quality
assessment. Though with the increase of concentration of stripping chemicals and temperature,
stripping percentages were improved; processing damage to the fabric such as losses in strength,
weight and pilling resistance ratings was found. In contrast, increased fabric absorbency was
found due to stripping | en_US |
