Abstract

The invention discloses a waterproof fluorescent whitening agent for fabric. The waterproof fluorescent whitening agent is prepared from 96%-98% of compound-type fluorescent whitening agent, 0.03%-0.3% of acid blue, 0.15%-0.3% of polyethylene glycol and the balance anhydrous sodium sulphate in a physical-mixing mode and an evenly-mixed mode. According to the waterproof fluorescent whitening agent for fiber fabric, as two fluorescent whitening agents are compounded, the whiteness improving force and the acid resistance of the waterproof fluorescent whitening agent for the fiber fabric are effectively improved, and the fiber fabric treated by the waterproof fluorescent whitening agent is high in whiteness, good in color fastness and excellent in overall performance.

Description

technical field [0001] The invention relates to the field of fluorescent whitening agents, in particular to a water-resistant fluorescent whitening agent for fabrics. Background technique [0002] Fluorescent whitening agent is a kind of fluorescent substance that absorbs ultraviolet light and emits blue or purple blue. It not only makes up for the blue light defect in the reflected light of objects with yellow color, but also increases the intensity of reflected light, so that the whiteness and brightness are significantly improved. The compounding of fluorescent whitening agent can get unexpected effects, which can improve the whiteness of dyed fabrics, reduce the amount of fluorescent whitening agent, improve application performance, change fluorescent color, and meet the special requirements of customers. There are mainly three methods for compounding fluorescent whitening agents: compounding fluorescent whitening agents with similar structures, compounding fluorescent ...
