| Abstract: | Effect of heat treatment time at 80 ℃ on melt spinning polyester polyurethane fiber which produced by prepolymer is discussed. It is pointed out that the linear density of this fiber increased with the increasing of heat treatment time,the intensity increased with the increasing of heat treatment time at first,then it will decreased with the increasing of heat treatment time .The heat treatment time has no effect on dry heat and wet heat shrinkage of the fiber while the extension at break and boiling shrinkage will increased with the increasing of it . |
