摘要：
A composite textured yarn contains a component yarn A and a component yarn B each false twisted and crimped. The component yarn B is shorter in yarn length or larger in shrinkage at least after heat treatment. Single fibers of component B have thick portions and thin portions successively alternating in the longitudinal direction.
