苎麻麻条的染色

Dyeing of ramie slivers

为解决麻条染色后板结凌乱、可纺性差，染色色花色差和重现性差的问题，开发了苎麻精梳麻条染色技术，即在前处理过程中添加膨松剂，在染色中加入尿素，以降低纤维间作用力；同时采用代碱剂NA取代碳酸钠固色，可提高染色重现性；合理控制纤维含油量为0．4％（omf），含潮率8％～10％，以提高可纺性。

In order to solve the hardened messy, low spmnabnlnty, color aevtation ana poor reproaucibility in dyeing, dyeing process of ramie combed slivers is put forward, including adding bulking agent in pre- treatment, adding urea to decrease the cohesion between fibers and using alkali alternative NA instead of sodium carbonate in dyeing, controlling the oil content in fiber of 0.4%（omf） and moisture regain of 8% - 10%.
