Use | Color fixing agent SE is a water-soluble low molecular weight polymer color fixing agent. It is a fiber specific color fixing agent used for dyeing wool, nylon, silk, leather, and other fabrics with anionic dyes (acidic dyes, metal complex dyes). After treatment, the dyed fabric has significantly improved water washing fastness, no color change, and there is no concern of contamination or adhesion after treatment. It is different from traditional tannic acid and tartaric acid. The fixing agent SE is a one bath fixing agent suitable for strong acidic, weak acidic, neutral and other dyes, and the fixing process and time can be greatly shortened. The fixing agent SE can provide excellent moisture resistance to treated fiber fabrics and significantly improve the color fastness of the fibers. After steaming, the printed fabric is treated with fixing agent SE, which can prevent the white part from being contaminated by dyes. The fixing agent SE will not change the color of the dyed fabric and will not be affected by steam fixation or soft processing. |
