发明名称 METHOD FOR PREPARING IMPROVED HEAT ADHESIVE POLYESTER AND POLYESTER BINDER FIBER USING SAME
摘要 The present invention relates to a method of preparing copolymerization polyester for a binder with improved heat adhesion, the method synthesizing copolymerized polyester with an acid component and a diol component. The acid component contains a terephthalic acid or an ester-forming derivative thereof and maleic anhydride (MA); or a terephthalic acid and an isophthalic acid or ester-forming derivatives thereof and maleic anhydride (MA). The diol component is ethylene glycol, or ethylene glycol and diol having a boiling point less than 300°C. In the acid component, the maleic anhydride (MA) is added therein during an esterification reaction. Further, the present invention relates to a polyester binder composite fiber using the same.
