Abstract

PURPOSE: Conjugate fiber is made by using a blend-colored polyester as the core component and a not blend-colored polyester as the sheath component and drawn, then treated with alkali and the sheath part is dyed to produce the titled fiber having finely roughnend surface and developing good black color.
CONSTITUTION: A polyester blend-colored with carbon blacked is used as the core component and another polyester not blend-colored, as the sheath component to effect melt-spinning to give sheath-core type conjugate fiber. The resultant conjugate fiber is drawn and treated with an alkali solution such as aqueous caustic soda to elute the fiber surface, preferably by 10W30wt% and form fine uneveness on the surface. Then, the resultant fiber is treated with a dye to dye at least at sheath part.
