The present invention relates to a polyester resin used for manufacturing a flame retardant fiber, and more specifically to a polyester resin which can be used for manufacturing a flame retardant fiber having not only flame retardancy but also excellent dyeability, with the introduction of a specific flame retardant material into a polyester compound polymerized to have the optimal composition and composition ratio.
本发明涉及一种用于制造阻燃纤维的聚酯
树脂,更具体地说,涉及一种聚酯
树脂,通过在聚酯化合物中引入特定的阻燃材料,聚合成具有最佳组成和组成比例的聚酯化合物,从而可用于制造不仅具有阻燃性,而且具有优异染色性的阻燃纤维。
