Banana belongsto the familyMusaceae and genus Musa. After harvest ofthe fruit,fibre could be extracted fromthepseudostemwhichis an agricultural wasteand could be used forvarious textile purposes. The present studywasundertakentoseethesuitabilityofikatdyed banana blends forfurnishings. Banana fibre was blended with viscose rayon intwo proportions of60:40and40:60andtwotypesofyarnsin45 tax were spun on cotton system. Two weft ikat designs suitable for furnishingswere evolved. Boththe blended yarnswere tied according to the designs and dyed with natural dyes (Natural indigo, Myrobolan and Chawali—kodi)asperthedesigns. Plainweavefabricwaswoven with2/ 205cotton yarn as warp and theblendedyarn as weftona frame loom. The fabric samples were tested fortheircolourfastness properties and costwascalculated.Theacceptabilityofthefabricsampleswasassessed by a panel offifty members constituting the postgraduate students and staffofHomeScienceCollege,ANGRAU,Hyderabad.The collecteddata wasanalysedusingonewayanalysisofvariance. xii Laboratorytestsforcolourfastnessrevealedthatblueandorange colourshad‘excellent‘fastness,whereas,yellowcolourhad'fair'fastness tosunlightandwashing.Allthethreecolourshadabetterrubfastnessin dry condition than inwetcondition.
