摘要
针对活性染料染色中未固着染料难以洗除的问题,选取5种活性染料对苎麻散纤维进行染色,并采用水洗,皂洗(非离子型洗涤剂),DMF-水(1∶1)回流和纯DMF回流4种方式进行洗涤,以洗除率为考察指标,并检测洗涤后的染色苎麻散纤维的耐水洗色牢度,评定这4种方式的洗涤效果。结果表明:DMF-水(1∶1)回流洗涤的洗除效果最佳,其洗除率达到47. 82%; DMF次之,为42. 39%;随后为皂洗,为40. 44%;水洗最差,只有38. 29%。经洗涤后的染色苎麻散纤维的耐水洗色牢度,DMF-水(1∶1)回流洗涤可达到5级,DMF为4～5级,皂洗为4级,而水洗在3～4级到4级之间。此外通过X射线衍射仪测得洗涤后的苎麻纤维的结晶度和取向度并未有明显变化,纤维素晶型仍为纤维素I。
Focuses on the difficulty of washing-off the unfixed dyes in reactive dyeing,5 reactive dyestuffs were selected to dye loose ramie fibers,subsequently treated by water washing,soaping (nonionic detergent),DMF-water mixture solution (1:1)reflux and DMF reflux.Both the dye removal rates of dyed samples treated by these four methods and their wash fastness values were determined to assess the washing performance.The results showed that the DMF-water mixture solution reflux had the best removal of the unfixed dyes,which dye removal rate was 47.82%,followed by DMF (42.39%), soaping (40.44%);and the worst was the water washing method,which was only 38.29%.In the wash fastness investigations,the dyed samples treated by DMF-water mixture solution reflux were at grade 5, while that treated DMF reflux were at grade 4-5,soaping were at grade 4,water washing ranged from grade 3-4 to grade 4.Besides,X-ray diffractometer analyses showed that the crystallinity and orientation of the treated ramie fibers did not change,and its cellulose lattice retained Cellulose I.
