Beschreibung
Zusammenfassung:	A conventional sea-island type composite fiber and its suede-like fabrics have poor color strength, and thus have problems such as an increase of a manufacturing cost and environmental contamination since they require a long time dyeing at a high concentration upon making the suede-like, fabrics. Further, they have a problem that the washing fastness and light fastness are low due to the use of a large amount of a dye. The present invention provides a sea-island type composite fiber, which has excellent color strength by containing a specific diol comonomer in island component, and its suede-like fabrics.
