Abstract: Apparatus for manufacturing fasciated spun yarn by false-twisting and detwisting a bundle of fibers. A fiber-diffusing section is provided, and utilizing differential fluid flow to separate and transfer free fibers in a stable manner for subsequent wrapping about the fiber bundle as it is detwisted.

Abstract: Disclosed herein is a twisted yarn comprising at least two bundled sheaves of staple fibers, each sheaf having an initial twist of substantially zero, the sheaves of staple fibers being mutually twisted to form the yarn. The coefficient of finishing twist utilization as defined in the specification is at least 150%. Also disclosed is a method of producing a twisted yarn comprising drafting a sheaf of staple fibers, supplying the sheaf to a bundling zone to reduce it to a bundled sheaf having an initial twist of substantially zero, drafting another sheaf in a similar manner, doubling at least two such bundled sheaves of staple fibers, and twisting them together.

Abstract: A process for making a fasciated spun yarn by drafting 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:and the overfeed ratio of the bundle of fibers during the false twisting operation is 5% at most. The fasciated spun yarn made by this process has a straight shape, resembles a ring-spun yarn and has sufficiently stable strength.

Abstract: 1061-82 PROCESS FOR MAKING FASCIATED SPUN YARN A process for making a fasciated spun yarn by drafting 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 fasciated spun yarn made by this process has a straight shape, resembles a ring-spun yarn and has sufficiently stable strength.
