摘　　要：比较了氯化改性和拉伸改性羊毛的染色性。氯化改性羊毛的上色速率、上染平衡比原毛快,各项色样牢度基本相同或略高;在拉伸羊毛的拉伸率较高时,其上染率和平衡上染率会明显提高;拉伸(不)定型和染色条件对染色性能有明显影响。选择了1:1金属络合染料、1:2金属络合染料和溴代丙烯酰类毛用活性染料对改性羊毛染色,探讨了染色机理,在两种改性羊毛达到了低温染色的要求,80℃时上染速度快、上染率高,能透染。The dyeing properties of wools modified by chlorination and drawing were compared. Compared with wool yarn,chlorinated wool had higher dyeing rate,quick to dyeing balance,and same or higher color fastnesses;The drawn wool with higher drawing ratio had improved dye uptake and balance uptake;the dyeing properties Were affected by drawing setting and dyeing conditions. These modified wools were dyed with 1:1 metal complex dyes, 1:2 metal complex dyes and bromoacryloylamine-based reactive dyes,and the dyeing mechanism was investigated,These two kinds of modified wools were suitable for dyeing at low temperature,and had high dyeing rate and uptake and osmotic dyeing ability at 80℃.
