ABSTRACT:
A plurality of synthetic fiber yarns which have latent bulk by virtue of false twist texturing or stuffer box crimping are pulled from a creel in the form of a warp between a first pair of rolls and then a second pair of slower moving rolls, passing through a steam chamber therebetween. This produces a pre-shrinking and evens out differences in tension and contractile force within the yarn ends, which renders them especially suitable for further processing as a warp, as in warp printing or dyeing. Since slack may periodically develop in individual ends between the first rolls and steam chamber, the first rolls are occasionally opened instantaneously, causing the slack to be taken out, and the rolls are then brought back together.
