Title:
POLYESTER-BASED FIBER HAVING IMPROVED WEATHERABILITY, ITS PRODUCTION AND FIBER PRODUCT USING THE SAME FIBER
Document Type and Number:
Japanese Patent JP2973846
Kind Code:
B2
Abstract:
PURPOSE: To extremely improve weatherability and increase strength retention of polyester-based fibers used in outdoor and exposed to strong ultraviolet ray for a long period of time.
CONSTITUTION: The object polyester-based fibers having improved weatherability and a fiber product using the fibers are composed of polyester-based fibers containing an ultraviolet absorber in an amount of ≤3.0wt.% to total weight of the fibers and containing the ultraviolet absorber in an amount of ≥3.0wt.% in the surface layer part corresponding to 25% of a cross section of a single fiber. Polyester-based fibers are dipped in a water dispersion of an ultraviolet absorber and squeezed so as an adhered amount of the ultraviolet absorber in a solid content to be ≤3.0wt.% by nip rollers, dried, and heat-treated at 200-220°C to contain the ultraviolet absorber in a concentration of ≥3.0wt.% in the surface layer part corresponding to 25% of a cross section of the polyester-based fibers.
