Abstract
In order to solve the problem that white powder is easy to appear in the dyeing of polyester bobbin yarn and difficult to remove,the causes of white powder production and composition analysis were studied,as well as the anti-sticking and dispersing effects of additives on the surface of white powder.The results showed that the main component of white powder was cyclic trimer of polyester oligomers.Increasing the amount of dye,the temperature of dyeing bath and extending the holding time could promote the oligo-mers to separate out from the fiber.The dispersant with moderate molecular weight and high degree of sulfo-nation had better anti-sticking and dispersing effect on oligomers on fiber surface.By TF-2501,TF-2500,TF-288E dyeing,there was almost no oligomer adhesion on the fiber surface,the oligomer particle size in the so-lution was small,and the dispersion effect was good.关键词
