| abstract | (57) [Abstract] [Problem] To be dyeable with a basic dye, excellent in deep color, strength, A high-speed and stable supply of polybutylene terephthalate-based composite fibers having excellent heat shrinkage properties and excellent strength retention after alkali reduction. SOLUTION: Polybutylene terephthalate obtained by copolymerizing 1.0 to 5.0 mol% of 5-sodium sulfoisophthalic acid and 0.03% by weight or more of inert fine particles have a melting point of 1. Weight ratio of crystalline thermoplastic polymer of 50 ° C. or more to 3 At 0:70 to 70:30, composite melt spinning was performed so that the component A was disposed in the sheath, and the mixture was cooled to a temperature below the glass transition point of the components A and B, and subsequently passed through a heating zone at an ambient temperature of 150 ° C or higher. By taking over at a speed of 2500 m / min or more, both the boiling water shrinkage and the dry heat shrinkage are 10% or less, and the strength is reduced. A composite fiber of 3 g / d or more is produced. |
