PURPOSE:To provide a conjugate fiber having high color-developing property and drapeability, giving a silk-like fabric having excellent feeling, most suitable for clothes, processable without causing problems, giving ultrafine fibers dyeable under normal pressure and effective in producing high-class clothes. CONSTITUTION:The objective splittable conjugate fiber is composed of at least two components A and B. The component A of the conjugate fiber is a copolymerized polyester containing terephthalic acid consisting the major part of the acid component and copolymerized with 8-15mol% of 5-sodium sulfoisophthalic acid and 5-40mol% of isophthalic acid and the component B is a copolymerized polyester containing terephthalic acid consisting of the major part of the acid component and copolvmerized with 1.7-5.5mol% of 5-sodium sulfoisophthalic acid. |
