Abstract (en)
[origin: WO9401604A1] Improvements to the manufacture of yarn spun on closed-end, high draft spinning systems, in which a yarn structure is formed in which each of the constituent fibres migrates between the surface and the core of the yarn so that part or parts of each fibre are trapped and bound by parts of other fibres in the yarn cross-section. The constituent fibres can migrate cyclically between the core and the surface of the yarn or the migration or withdrawal of individual fibres can be impeded by a degree of inter-fibre entanglement deliberately introduced in the yarn structure. Mechanisms for producing the yarn structure are also described.
