锦纶染色中匀染剂的选用

在锦纶染色生产中引入缓冲体系后，匀染剂的选用及用量对锦纶染色色差控制起关键作用。研究结果表明，利用缓冲体系将pH值控制在4～6．5，染浅色时，可加入匀染剂FTS-T2％～3％；染中深色时可加入匀染剂TBW-950．2～0．8g／L，可达到良好的匀染性和重现性。大生产时，可根据小样试验将匀染剂用量放大25％。

Selection of leveling agent for nylon dyeing

Based on practice, it is recognized that selection and dosage of leveling agent in nylon dyeing are key to control the color difference between bulk and laboratory samples. As a result, pH value can be controlled to 4~6.5 by use of buffering system, and add leveling agent FTS-T 2%~3% during light dyeing, and add leveling agent TBW-95 0.2~0.8 g/L during deep dyeing, so as to obtain good levelness and reproducibility. The dosage of bulk production should be increased 25% than sample dosage.
