| Abstract: | Cotton yarns were coated with a polymer solution to hold surface fibers to the yarn body, which caused fiber-fly generation
during knitting process. The physical property of the coated yarn, especially a bending rigidity was investigated in order
to evaluate the performance of the coated yarn during knitting. SEM images showing the surface condition of the coated yarn
demonstrated that the thickness of a coating material increased as the concentration of the coating solution increased. The
results of the bending rigidity measured using KES-FB2 system showed that the bending rigidity of the coated yarn increased
as the concentration of the coating solution increased. The results also revealed the possibility that yarn coated with a
low amount of coating material should be employed for further research of reducing fiber-fly generation during knitting process. |
