摘要
We have studied the elastic recovery and inverse relaxation phenomena of polyester staple fiber rotor spun yams. Better fiber orientation obtained with a drawing passage before spinning results in higher permanent deformation and lower delayed elastic recovery of the yarn. Yam twist has little influence on elastic characteristics. The stress produced in the yam when strained at 10% is higher when fibers are straighter and lower when twist increases. The inverse relaxation effect increases with the level of orientation of the fibers in the yarn.
