Description :
Use of solar energy and natural sources for dyeing is simple, economical and ecofriendly.In this study an attempt has been made to optimize time for dye extraction, dyeing and temperature for dyeing of silk fabric with natural dye source i.e. flowers of flame of forest (Palas) in tie and dye using solar energy. Tying styles such as spot, circular, spider web, line, and marble were used for tying of fabric. Solar cooker was used for dyeing as well as extraction of dye from dye source. Based on color strength values, temperature and time for dyeing was optimized. Tinctometer was used to test color strength of dye solution at selected time intervals and temperatures. At optimized dyeing time and temperature using solar energy, tie and dye samples were prepared, washed thoroughly dried and evaluated visually for various criteria using 5 point scale Samples dyed in acid dye were used as control samples. It was concluded from this study that- Utilization of solar energy for dyeing of silk fabric with flowers Palas in tie and dye was successful; optimized temperature was 55-65 oC , optimized dye extraction time was 3 hours, optimized dye quantity was 9 gms & dyeing time was 3 hours & the score of tie and dye samples dyed at optimized time and temperature was highest.
