Title:
POLYESTER-BASED THERMOADHESIVE CONJUGATE FIBER AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP3778808
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyester-based thermoadhesive conjugate fiber composed of a polyalkylene terephthalate as the fiber-forming component and a noncrystalline polyester as the thermoadhesive component, and capable of giving a high-grade fibrous structure with good dimensional stability hard to cause its deformation even if used in a high-temperature atmosphere, and to provide a method for producing the above conjugate fiber.
SOLUTION: This polyester-based thermoadhesive conjugate fiber is composed of a thermoadhesive component consisting of a noncrystalline polyester 50-100°C in glass transition point having no crystal melting point and a fiber-forming component consisting of a polyalkylene terephthalate ≥220°C in melting point. This conjugate fiber has the number of crimps of 3-40/25 mm, crimp percent of 3-40%, and web area shrinkage of ≤20%.
