Abstract

본 발명은 정규 폴리아미드와 정규 폴리아미드에 비해 아미노 말단기와 카르복실 말단기의 수가 50% 이상 차이나는 개질 폴리아미드를 혼합하여 방사하므로써, 별다른 설비투자 없이도 염색성이 개량된 폴리아미드 섬유를 제조할 수 있는 방법에 관한 것이다.The present invention provides a polyamide fiber with improved dyeability without the need for equipment investment by mixing and spinning modified polyamide having a difference of 50% or more of amino and carboxyl end groups compared to regular polyamide and regular polyamide. It is about how it can be.
