Problems solved by technology

[0004] However, if such a high-molecular-weight phosphorus compound is used as a fire retardant, it has been difficult to impart sufficient fire resistance to synthetic fibers, especially polyester fibers containing CDP (cationic dyeable polyester).
In addition, although there are known substances that can impart fire resistance, these substances have poor dispersibility at high temperatures, contamination of dyeing machines, and deterioration of light fastness of disperse dyes are serious problems.

Abstract

A dispersion of a flameproofing agent for fibers which is obtained by dispersing a flameproofing agent which is an aromatic phosphate compound represented by the following formula (1): (wherein R1, R2, R3, and R4 each independently represents hydrogen, etc.) and an ultraviolet absorber in water in the presence of a surfactant. Use of the dispersion for flameproofing synthetic fibers, especially CDP and polyester fibers, can impart excellent long-term flameproof performance to the synthetic fibers.

Description

technical field [0001] The present invention relates to a dispersion liquid of a phosphorus fireproofing agent for fibers, a fireproofing processing method using it, and fibers obtained by performing fireproofing processing therefrom. More specifically, it relates to a dispersion of a fire retardant for fibers obtained by dispersing an aromatic phosphate ester compound as a fire retardant, preferably together with an ultraviolet absorber, in water in the presence of a surfactant, and fire retardant processing using the same The method and the fiber obtained by carrying out the fireproof processing thereof. By using the dispersion liquid of the present invention, it is possible to impart fireproof performance excellent in durability to fibers. Background technique [0002] Conventionally, as a method of imparting flame retardant properties by post-processing synthetic fibers, a method of attaching a flame retardant agent obtained by dispersing a halogen compound as a flame r...
