摘要
采用4种常见的活性染料三原色组合,即Cibacron FN型、Levafix CA型、Novacron NC型和Remazol型染料对纯棉针织物进行染色,测试并分析了加碱方式、染色浴比、纯碱用量对织物色光的影响。结果表明,采用高温加碱染色工艺,织物不易染花;Cibacron FN型和Novacron NC型染料对浴比依存性较大,Remazol型染料对浴比依存性适中,Levafix CA型染料对浴比依存性较小;纯碱用量对织物色光影响较大;化验室小样染色工艺能够为大生产工艺提供方向,浴比及加碱量的精确控制是提高化验室配方到车间再现性的必要措施。
Cotton knitted fabrics were dyed by four kinds of common three primary colors group of reactive dyes, including Cibacron FN, Levafix CA, Novacron NC and Remazol type dyes.The effects of the way of adding alkali, the ratio and the dosage of sodium carbonate on color shade were tested and analyzed. The results show that fabric has no dyeing defect when dyed by the process with adding alkali at high temperature; the bath ratio dependency of Cibacron FN and Novacron NC type dyes is big, the bath ratio dependency of Remazol type dyes is moderate, and the bath ratio dependency of Levafix CA type dyes is small; the effect of the dosage of sodium car- bonate on color shade is big; the sample dyeing process in laboratory can provide direction for large scale process; the accurate control of bath ratio and the dosage of sodium carbonate is the necessary measures of improving repro- ducibility from laboratory to large scale process.
