This liquid fluorescent brightener has the structure ofbis (triazinyl) aminostilbenes. It has rather high fastness when it was applied in fibers. Its most notable features is the better stability on pH. It has substantivity and connectivity on bleaching pulp. And it can also be used in adding the pulp, coating, spraying. This paper makes experiment in optimizing process conditions of preparation and use the nanofiltration membrane to remove the salts and to concentrate the product. From this paper, achieve the clean production processes and get the products with high economic value, super quality and competitive price.
