Abstract
Production of a composite yarn from continuous filaments by continuously advancing at least two assemblies or tows, each contg crimped continuous filaments differing from those in any other tow, in known manner through opening and crimp de-registering zones and thereafter splitting the resultant composite tows into a series of strips each of which is collected as a composite yarn, but, in particular carrying out the tow opening and crimp de-registration on each tow separately before combining them to a composite tow and splitting this into strips and winding these up separately to produce bulby yarn.
Blended fibre manufacturing method, involves heat-deformable blended fabric from staple fibres, continuous yarns, split fibres and flat yarns, by weaving together primary yarn system from staple fibre
