in pace with the raising of setting temperature , the crystallinity, degree of orientation and size of crystal grain will be increased, dye uptake rised, but the dyeing evenness declined.
聚酯细旦丝随着定形温度的增加,结晶度、取向度和晶粒尺寸增加,上染率提高,同时匀染性降低。
the spinning conditions which influence the dyeing evenness of polyester dty including spinning temperature, filter medium, air cooling and the chips quality are investigated.
