Paper Title:
Process Structure and Properties of Bi-Shrinkage Yarns Spun by one-Step Spinning Process
  Abstract

Aggregation structure and properties such as crystallinity, orientation, mechanical properties, boiling water shrinkage of high-shrinkage component, low-shrinkage component, and the bi-shrinkage yarns which are spun at different process conditions are characterized and tested. The high-shrinkage component and low-shrinkage component spin individually, the bi-shrinkage yarns spun by one-step spinning process. The research indicates that with the spinning speed increases, the degree of crystallinity and orientation of the high-shrinkage component increases, and its tensile strength increases, elongation at break decreases, boiling water shrinkage attain the highest value when the spinning speed is 3,000 m/min; With draft ratio decreased, the orientation, crystallinity, tensile strength, initial modulus of the low shrinkage component decrease, and its elongation at break, boiling water shrinkage increases; as the draft ratio decrease, BSY crystallinity decreased, orientation first increases, then decreases, strength, initial modulus decrease slightly, boiling water shrinkage increases; H1 increases from 80 °C to 95 °C, BSY crystallinity gradually increased; degree of orientation decrease, strength, initial modulus increases and elongation decreases, boiling water shrinkage increases firstly,and decreases slightly afterwards; with the H2 temperature increases, BSY crystallinity increase, orientation first increased and then decreased slightly,the tensile strength reduce a little, elongation at break increase, initial modulus decreased, boiling water shrinkage decreased.
