It is the combination of sweat components and energy in sunlight that makes some dyes with good color fastness to perspiration and light fastness, but poor fastness to perspiration and light.
The reason may be that the dye undergoes a complex oxidation-reduction reaction under the combined action of light, sweat and oxygen, which leads to the breakage of the azo bond in the dye or the destruction of other chromophoric groups, causing the dye to fade.
[0003] Reactive dyes have complete chromatograms, low price, and wide application, but their light fastness to perspiration is poor. Although some companies have successfully developed a few dyes with better perspiration light fastness, their chromatogram is limited and expensive, which cannot meet the needs.
[0004] At present, the perspiration and light composite fastness improving agent adopted in the conventional method has single performance and cannot satisfy the simultaneous improvement of sweat and light fastness at the same time, such as the perspiration and light composite fastness improving agent UVS-327 produced by Riken Corporation of Japan. The development and research of a new sweat-light composite fastness enhancer is highly anticipated by the relevant departments

Abstract
The invention discloses an agent for improving the composite fastness to light and sweat and its application. The components of the agent for improving the composite fastness to light and sweat include: hydroxyphenylbenzotriazole, benzophenone derivatives, and salicylic acid derivatives , SiO2, sodium cinnamate, nitrobenzene derivatives, terephthalaldehyde derivatives, ethylene glycol monoethyl ether. The perspiration and light composite fastness improving agent of the present invention can improve the perspiration and light fastness of various active dyes by 1-2 grades, and can meet the needs of relevant departments.
Description
Technical field [0001] The invention relates to a printing and dyeing auxiliary, in particular to a perspiration-light composite fastness improver. Background technique [0002] Perspiration composite fastness is abbreviated as perspiration fastness, which refers to the resistance of the color of textiles to the combined effects of human sweat and sunlight during the course of taking it. The components in the sweat and the energy in the sunlight will act on the dye and cause the dye to change color. It is the combination of sweat components and the energy in sunlight that make some dyes with good perspiration and light fastnesses, but poor perspiration and light fastnesses. The reason may be that the dye undergoes a complex oxidation-reduction reaction under the combined action of light, sweat and oxygen, which leads to the breaking of the azo bond in the dye or the destruction of other chromophoric groups, which causes the dye to fade. [0003] Reactive dyes have complete chroma...
