Properties of Specialty Yarns Based on Raw and Dyed Cotton

摘要

During the manufacture of specialty yarns by blending dyed cotton and raw cotton, fibers damaged by the dyeing process degrade the physical properties of the specialty yarns. For a raw cotton blended with a large amount of dyed cotton, the spinnability of the specialty yarn worsens due to the disparity of the raw materials, which makes fine count specialty yarns difficult to manufacture. The basic properties of the component fibers of a specialty yarn, such as strength, elongation, unevenness, and spinnability, are analyzed as a function of the blending ratio of the dyed cotton to provide reference properties for fine count specialty yarns.
