Abstract

The invention belongs to the technical field of fluorescent whitening agents and particularly relates to a fluorescent whitening agent for chinlon. The technical problems that existing fluorescent whitening agents for chinlon are low in chinlon whiteness improving value and high in cost are solved mainly. The technical scheme is that the fluorescent whitening agent for chinlon is formed by evenly mixing, by weight parts, 5-10% of component I (fluorescent whitening agent 357), 80-90% of component II (fluorescent whitening agent 351), 0.01-0.3% of acid blue, and the balance anhydrous sodium sulphate in a physical mixing mode. The fluorescent whitening agent has the advantages of being high in chinlon whiteness improving value and low in cost.

Description

technical field [0001] The invention belongs to the technical field of fluorescent whitening agents, in particular to a fluorescent whitening agent for nylon. Background technique [0002] 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 whitening agents with different structures, and compounding by adding sensitizing dyes. [0003] People of different races or have different preferences for colors, and have different understandings of "white". Some people think reddish light looks whiter, while others think blue light looks whiter. Due to these special requirements for visual whit...
