MANUFACTURING METHOD OF POLYESTER FIBER ADDING FIRE RETARDANT AGENT AND ANTI-PILLING MATERIAL TO GIVE FIRE RETARDANCY AND ANTI-PILLING PROPERTY

摘要

PURPOSE: A manufacturing method of polyester fiber having fire retardancy and anti-pilling property is obtained by containing a fire retardant agent and anti-pilling material. CONSTITUTION: Polyester fiber having fire retardancy and anti-pilling property is obtained by the steps of: using a dicarboxylic acid ingredient and a diol ingredient; adding 0.3-0.8wt.% of a fire retardant agent(formula I) based on phosphorus and 0.03-4mol% of anti-pilling material(formula II); and then polymerizing the ingredients and the materials. The anti-pilling material is phosphoric compound having three functional groups.
