PROBLEM TO BE SOLVED: To enable the sizing of a cloth to give excellent smoothness and abrasion resistance while suppressing the generation of fluffs by using a sizing agent composition produced by compounding a carboxyl-containing polyvinyl alcohol with a specific phosphoric acid ester compound. SOLUTION: A sizing agent composition is produced by compounding 100 pts.wt. of a polyvinyl alcohol resin containing 0.1-10 mol.% of carboxyl group and having an average polymerization degree of 100-10,000 with 0.1-20 pts.wt. of a phosphoric acid ester compound of formula [R is H, an alkyl or an alkylallyl; (n) is an integer; R' is H or R(CH2 CH2 O)n ] or its salt. An aqueous sizing liquid containing 2-20 wt.% of the sizing agent composition is applied to a yarn in an amount of 5-20 wt.%, preferably 5-10 wt.% and the fiber is oiled and dried to complete the sizing treatment. |
