芳纶1313的超高温染色研究

Dyeing properties of Aramid 1313 under ultra high temperature

芳纶1313有较好的超分子结构立体规整性,玻璃化温度很高,现有染整设备难以达到理想的染色效果,大量载体的加入使染色成本居高不下,同时载体造成的污染也很严重。在染色基本理论指导下,文章设计制造了最高染色温度可达200℃的超高温染色机,研究了超过目前行业最高130℃染色条件下,分散染料对芳纶1313的染色效果。结果表明,分散染料在140℃染色时,可以减少2/3的载体用量,经济效益和环境效益显著。研究发现:由于染料稳定性的限制,更高温度条件下的染色有待于染料的改进才能完成。文章对芳纶1313染色的途径进行了有益的试探,对类似问题的解决提供了新的参考方法。

Aramid 1313 has a good regularity supramolecular structure, and its glass transition temperature is very high. It is difficult to achieve the ideal dyeing effect by using existing dyeing and finishing equipment, so it should add a lot of carrier to complete dyeing, but this will cost much and cause pollution. Under the guidance of the basic theory of dyeing, the ultra high temperature dyeing machine was manufactured, the dyeing properties of Aramid 1313 by disperse dye under ultra high temperature（over 130 ℃ ） was studied in the paper. The results showed that a better dyeing effect was obtained under 140 ~C and it can reduce two-thirds of the carrier＇s dosage, economic and environmental benefit was remarkable. It also showed that because of the limitation of dye stability, dyeing under higher temperature need the improvement of dye. Paper sounds out the way of Aramid 1313 fiber dyeing, and provides a new referenced method to solve similar problems.
