Abstract
Abstract A sized cellulosic fiber-containing yarn having an excellent weaving property and processing property is provided by sizing, in a non-aqueous medium, with a copolymer prepared by copolymerizing 20 to 80% by weight of at least one monomer selected from the group consisting of methyl methacrylate, styrene and acrylonitrile and 80 to 20% by weight of at least one monomer selected from the group consisting of acrylic esters of aliphatic alcohols having 1 to 8 carbon atoms and methacrylic esters of aliphatic alcohols having 4 to 8 carbon atoms, and removing the non-aqueous medium from the yarn, the copolymer having a glass transition temperature of 40° to 80°C and a Young's modulus of 1 × 10 3 to 1 × 10 4 kg/cm 2 .
