| Abstract: | High shrinkage polyester staple was prepared by using amorphous polyester chip. The technology of drying, spinning, drawing and non-setting was studied. The result showed: using existed equipment, high shrinkage polyester staple could be made at lower spinning temperature,lower pre-drawing ratio, lower temperature drawing and non-setting. |
