seed yarn

Design and spin fancy yarns with polyester filament,mainly spiral yarn,seed yarn and circle yarn,and test the fineness,tensile break strength,elongation and twist of the spinned yarn,which provides the material performance basis for the late fabric design.

对涤纶长丝纺制花式线进行花样设计,主要是螺旋纱、结子纱、圈圈纱,并对纺制出的花式纱线的细度、拉伸断裂强度、断裂伸长率及捻度等性能进行测试,为后期的面料设计提供了材料性能依据。
