拉细羊毛Lanasol CE染色性能研究

Dyeing Optim fiber with Lanasol CE dyestuff

采用Lanasol CE染料对拉细羊毛进行染色,研究纤维修补剂WLX和毛用匀染剂WPN对纤维染色性能的影响.结果表明,修补剂WLX和匀染剂WPN可以明显降低Lanasol CE染料对拉细羊毛的上染速率,明显提高匀染性,而不影响竭染率、固色率以及染色羊毛的K/S值;同时显著降低拉细羊毛在染色过程中所受的损伤,改善染色羊毛的手感.与Lanasol CE染料配套匀染剂Albegal B相比,80s、90s染色拉细羊毛单纤强力分别提高13.26%,16.52%,不同匀染剂对应染色拉细羊毛色牢度相当.

The effect of repair agent WLX and leveling dyeing agent WPN was investigated on Optim dyed with Lanasol CE dyestuff.It is found that WLX and WPN can obviously reduce the dyeing rate to promote the level dyeing of Optim dyed with Lanasol CE dyestuff,and the dyeing exhaustion,fixation and the K/S value are not weakened.Compared with the level dyeing agent Albegal B matched with Lanasol CE dyestuff,WPN and WLX can reduce the damage to Optim during the dyeing process and improve the handle obviously.The strength of molofilament is improved by 13.26% and 16.52% separately when tested at 80s and 90s Optim fiber.The colour fastness of Optim dyed with WPN stand as it is used to be.
