摘要：

In order to investigate the influence of roving parameters on the appearance and properties of cotton/ polyester sheath-core staple yarns by the two-step spinning process, the effects of factors such as spinning settings, roving linear density, roving twist and core/ sheath fiber ratio on the exposure of core fiber and yarn properties were studied. With the help of image processing technology, the core fiber exposure ratio was quantitatively measured. The results show that as the width of fiber bundle output from roving frame increases from 10. 2 mm to 16. 3 mm, the eccentricity of core fiber bundle in roving decreases from 26. 5% to 19. 2%, and the exposure ratio of core fiber in yarn decreases by 11. 3% (29. 2 tex) and 12. 3% (19. 4 tex). When the roving count increases or the twist coefficient decreases, the core fiber exposure proportion decreases. When the proportion of polyester core fiber increased from 15% to 25%, the exposure proportion of core fiber increased by 35. 6% (29. 2 tex) and 30. 5% (19. 4 tex). © 2022 China Textile Engineering Society.
