CRIMPING APPARATUS FOR MANUFACTURING A BULKY YARN

摘要

An air-jet type crimping apparatus equipped with a fiber ejection nozzle of an increased thermal effect, a rotational crimping member having a surface on which are peripherally arranged needle or honey-combed protuberances defining a multiplicity of spaces receptive of the fibers ejected by the nozzle composing the yarn and cone-type means for taking up the yarn from the surface at speeds automatically adjusted according to variations in the thermal shrinkability of the processed fibers. Fiber cooling means may advantageously be added for enhanced stability of the crimps imparted to the fibers.
