Mango Kernel Starch – An Effective Sizing Agent For Cotton Yarns

Abstract

Starch is a sizing agent used in textile industry for stiffening of warp yarns before putting them on warp beam. Starch can be extracted from waste mango kernels after processing by a simple laboratory method. Mango kernel starch is white, odorless and has good pasting and film forming property. It is environmental friendly, bio-degradable and a low cost non-conventional starch. Eco-standards relating to textile finishing can be suitably adopted in the use of mango kernel starch as sizing agent on warp yarns. Cotton yarns sized with mango kernel starch exhibited decrease in yarn count, elongation percent and yarn hair count per 100 mt. of yarn and increase in the strength and RKM with the increase in the percent of mango kernel starch applied.
