| Abstract: | In present work, PET FDY has been used to blend with diacetate filaments by air texturing process and core-and-effect air-textured
yarns have been produced. The influences of both over-feeds of core and effect components on properties of textured yarns
were mainly examined. It was observed that a spun-like effect of diacetate filaments occurred during air texturing and there
were a little amount of free fiber ends besides loops on blended air textured yarns, while the number of free fiber ends changed
little with variation in over-feeds. The tenacity of textured yarns decreased with increase in over-feeds of effect or core
component. The breaking elongation increased with increase in over-feed of effect component, but decreased with increase in
over-feed of core component. The yarn stability improves when both over-feeds are increased. The effect of over-feeds on boiling
water shrinkage shows no clear trend. The core and average diameters are higher at high over-feed of effect component, but
the over-feed of core component exhibits little effect on yarn diameters. The number and size of loops are increase with increased
over-feed of effect component. |
