摘　　要：在分析分散染料可染丙纶的形态结构、化学结构、热性能、结晶度及物理机械性能的基础上，采用分散红FB、分散黄E-3G和分散蓝2BLN对分散染料可染丙纶进行染色。通过单因素和正交试验及极差分析，确定了最佳染色工艺：T=130℃，t=90min，pH为4．5，浴比1：50。实验结果表明：在该染色工艺下的可染丙纶针织物的上染率在72％以上、K／s值在6．3以上，但色牢度比常规涤纶染色品低1～1．5级。In this paper, firstly the surface morphology, chemical structure, crystallinity, thermal, physical and mechanical properties of dyeable PP fiber with disperse dyes were analyzed. On this basis, disperse red FB, disperse yellow E-3G and disperse blue 2BLN were used to dye dyeable PP fiber with disperse dyes. Mono-factor, orthogonal experiments and range analysis were carried out to confirm the optimal dyeing process. T=130℃, t=90 rain, pH=4. 5 and liquor ratio 1 ：50. The results show that dye-uptake of dyeable PP fiber with disperse dyes under such technology is above 72%, and K/S value exceeds 6. 3, but color fastness is 1-1.5 lower than Dacron.
