METHOD OF MANUFACTURING POLYESTER FIBER WITH FIRE RETARDANT AND ANTI-PILLING PROPERTIES

摘要

The present invention is a method for producing a polyester fiber having flame retardancy and anti-pilling properties.;The present invention polymerizes a polyester polymer with dicarboxylic acid and a diol component, and melt-spun and stretches the polymer to produce polyester fibers.At the time of polyester polymerization, a flame retardant of the following general formula (I) and a general formula ( The method is characterized in that the polymerization is carried out by adding the anti-pilling agent of II).
