Title:
POLYESTER-BASED CONJUGATE FIBER EXCELLENT IN FASTNESS
Document Type and Number:
Japanese Patent JP3230686
Kind Code:
B2
Abstract:
PURPOSE: To obtain the subject fiber, suitable as a raw material for nonwoven fabrics according to a hot bonding method and dyeable with a disperse dye by using a polyester as a core component and polyethylene as a sheath component and regulating the thickness of the sheath component to a prescribed value or below and the residual elongation to a prescribed value or above.
CONSTITUTION: The objective fiber is core-sheath type conjugate fiber containing (A) a core component of a polyester and (B) a sheath component of polyethylene. The thickness of the polyethylene which is the component (B) is ≤15μm and the residual elongation is ≥20%. The above-mentioned fiber is dyeable with a disperse dye.
