1.
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。
5) spinning coil
纺纱纱圈
6) independent quadrilaterals
四圈
1.
If d(x)+d(y)≥83k for each pair of vertices x∈V_1,y∈V_2,then G is covered by k independent quadrilaterals.
设k是正整数,G=(V1,V2;E)是一个二部图,满足|V1|=|V2|≥2k+1,若对G中任意的两个顶点x∈V1,y∈V2,都有d(x)+d(y)≥83k,则G恰好被k个独立的四圈所覆盖。
