Air-jet texturing of filament feed yarns of different shrinkage potential

Abstract

The possibility of feeding filament yarns with different shrinkage potential in air-jet texturing has been studied. Parallel-end air-jet texturing of filament yarns with different shrinkage potential results in decrease of bulk with the increase in shrinkage difference level initially, but then increases with further increase in shrinkage difference. Instability of air-jet textured yarns also first decreases and then increases with the increasing shrinkage difference. The study suggests that shrinkage difference in the feeder yarn is not an effective way to increase the bulk of air-jet textured yams.
