Title:
PHOTOCHEMICAL AND THERMAL STABILIZATION OF UNDYED AND DYED OR PRINTED POLYESTER FIBER MATERIAL
Document Type and Number:
Japanese Patent JP3258113
Kind Code:
B2
Abstract:
PURPOSE: To prevent a polyester fiber material from action by ultraviolet rays and remarkably improve photochemical and thermal stabilities by treating undyed or dyed polyester fiber with a specific compound.
CONSTITUTION: Dispersion obtained by dispersing a triazine-based ultraviolet absorber comprising a compound of the formula [R1 is H or a 1-5C alkyl; R2 is a 1-12C alkyl; (n) is 0-5], preferably a compound of the formula [R1 and R2 are mutually independently each a 1-4C alkyl, preferably methyl or ethyl; (n) is 1-3] into water by a surfactant is added to the interior of a dyeing bath or printing paste containing a disperse dye whose pH is adjusted to 4.5-6.5 to subject a polyester fiber material to dyeing treatment in the dyeing bath or the printing paste. The resultant dyed or printed polyester fiber material (or including undyed polyester fiber material) remarkably improves light and thermal stabilities and is extremely effective as an interior material for automobiles. Furthermore, an amount of the ultraviolet absorber used is preferably 0.5-7.5%owf.
