1061-82 PROCESS FOR MAKING FASCIATED SPUN YARN ABSTRACT OF THE DISCLOSURE A process for making a fasciated spun yarn by draft- ing and pneumatically false twisting a bundle of staple fibers is disclosed. In the method, the width W (mm) of a bundle of fibers measured just upstream of the nip point of a pair of second rollers of a drafting zone and a yarn count N (Nm) of the spun yarn are set to satisfy the following equation: 60/??W ? 170/? and the overfeed ratio of the bundle of fibers during the false twisting operation is 5% at most. The fasciat- ed spun yarn made by this process has a straight shape, re- sembles a ring-spun yarn and has sufficiently stable strength.
