摘　　要：本文以松弛热定型的方式对分散染料可染丙纶分别在１０５，１１０，１２０，１３０，１３５，１４０℃处理２０ｍｉｎ．采用Ｘ－ｒａｙ衍射法测定试样的结晶度，并计算（１１０）晶面法线方向的晶粒尺寸；测定了定型前后的试样在常压沸染下的上染率．从而，研究了试样定型前结晶结构与纺丝成形条件的关系、定型后结晶结构的变化及其与上染率的有机联系．he dyeable PP Fibers were treated for 20 min at 105,110,120,130,140℃ respectively. The crystallinity and crystal size along the normal line direction of the (110)crystal surface were measured by X-ray diffractometers. Both set and un-set samples were boiling dyed at normal pressure and their dye uptakes were measured.The relations between crystal structure and fiber forming conditions before setting and the effect of the changes in crystal structures upon dye uptake after the process were studied.
