摘　　要：将可染组分与聚丙烯共混改性,纺得了可染丙纶,可纺性好;主要性能变化不大;分散染料的上染量提高3～5倍以上;色牢度达4.5～5级,色泽鲜艳,手感柔润。上染率提高的主要原因是改性丙纶结构疏松,结晶度较低。Polypropylene mixed with dyeable compositions has been spun into dyeable PP filament(fine denier).Spinability is satisfactory.Main properties remain little change.The dye-uptakeof disperse dye increases by over 3～5 times.The dyed fibres possess good fastness to soaping andrubbing.It also has bright color and soft handle.The primary reason for changing color-ability is because the modified PP fibre has loose structure and lower crystallinity.
