Synthetic yarn crimping nozzle - has vortex chamber in which terminate compressed air supply ducts and attachment whose dia. is greater than propagating cone of air flow

摘要

Synthetic yarn crimping nozzle has a vortex chamber in which terminates =1 radial channel serving for the supply of compressed air, the outlet of the chamber being associated with a co-axial attachment which is provided with a bore whose dia. is greater than the conical formation of air flow in the attachment. Single yarns can be texturised successfully, the yarns retaining their texture even when stressed during subsequent processing.
