Abstract: The performance of starch and other sizing materials for cotton yarn has been investigated at different relative humidity by studying their film properties, adhesion to cotton and weaving performance. At low humidity, the poor weaving performance of cotton yarn sized with starch is due to the lower film extension and poor adhesion caused by low moisture regain. Hydroxyethyl starch (HES) gives excellent weaving performance of cotton yam at 65% RH. Among the synthetic sizes, polyvinyl alcohol (PYA) gives excellent low RH weaving of cotton yarn even at low add-on. Polyacrylamide (PAM) is less effective but permits, at low add-on, satisfactory low RH cotton yarn weaving. Carboxymethyl cellulose (CMC) is useless for low RH weaving of cotton yarn. Among the blended size recipes studied, HES/Starch (50:50) and PAM/Starch (10:90) .give excellent weaving performance at low RH and are most economical.
