Long Li Long-term supply anti-stained pink anti-agent, sincerely with our customers to develop anti-stained pink recruit agents nationwide and improve together for a better future. Fixative properties and characteristics of the dye fixing agent to improve wet fastness common basic additives, especially for direct, acid dyes f high price of raw powder resist basically must be used. With the market increasingly high demand for color fastness, the general Shen Nong color reactive dyes is also used fixative to ensure color fastness. Fixative are currently no formaldehyde, most fixative stable performance in weak acid bath powder resist direct, effect is relatively the best. But it is for shade, more or less have some impact, if in use for DH value, temperature and other process conditions control is lax, it will affect the stability of the anti-pollution pink shade, and sometimes even the mere mention of a greater cause. Fixative basically for the cationic, anionic dye so has an effect. After staining due to fixing things in general no longer be washed, so if the refurbished former remaining in fixative and sufficiently removed from the reaction product of the dye on the fiber, which added dyes stained color correction, will not only dye dyeing speed becomes very fast, but also to make it lose the ability to transfer dyeing, color flower generation is inevitable, and this time was even more plus leveler is useless. If staining was already baked, then reflect more prominent.
