Investigation into reactions of starch with monochloro triazinyl- {beta} Cyclodextrin and Application of their Products in Textile Sizing

Abstract

Chemical modification of starch and hydrolyzed starches through their reaction with reactive cyclodextrin (RCD), namely, monochloro triazinyl-B cyclodextrin was investigated under a variety of conditions. Results obtained signify that the reaction is favoured in alkaline rather than in acidic media and in shorter than larger liquor ratios. Maximization of the reaction could also be achieved at 40 degree C for 60 minutes. Of the several alkaline catalysts used NaOH proved to be the best when used at a concentration of 10 g/1. Reaction of starch and hydrolyzed starches with RCD is determined by concentration of the latter. It brings about polymeric products the apparent viscosity of which depends on both the extent of reaction, expressed as nitrogen percent, and degree of acid hydrolysis prior to the modification. Evidence for involvement of starch and RCD by chemical bonding is evidenced by FTIR analysis. Furthermore the newly synthesized starch based polymeric products were applied to light cotton fabric and evaluation of the sized materials through monitoring size add-on, size removal and strength properties of the fabric made.
