Peregal O is a non-ionic surface active agent, mainly composed of polyoxyethylene aliphatic alcohol ether, which is milky white or beige paste and freezes when it is cold. It is soluble in water and stable in hard water, acid or alkali.
Appearance is milky white or beige paste, easily soluble in water, ethanol, ethylene glycol, etc., solubility in cold water than in hot water, non-ionic surfactant. Saline fog point (10%)73℃, pH6.5 ~ 7.5. The pH of 1% aqueous solution is close to neutral and is stable to acids, bases, and hard water. It has good evenness, slow dyeing, permeability, diffusion and scouring aid for all kinds of dyes, and is also an excellent oil-in-water emulsifier. Can be used with all kinds of surfactants and dyes in the same bath. When used as levelling agent in dyeing bath, it should not be used in the same bath with anionic surfactant.
Usually used as a levelling agent. Such as direct, reduction, acid metal complexation, dispersion, cationic dye dyeing levelling agent. When used for direct dye dyeing, the dosage is about 0.2-0.5 g/L. Used for dyeing elastic polyamide silk with disperse dyes, the general dosage is I% 14%. The dosage for cationic dye dyeing is 0.2-1g /L; Used as a diffuser to prevent the decomposition of some Naftol dyes from getting on the fabric and contaminate the color products; For stripping agent; As EP flower anti-dyeing agent, the color depth varies according to the amount of Peregal O, the general amount is 5-100g /L; As anti-white auxiliaries, blue BB bessi brightening agent, raw hair cleaning agent, reactive dye printing cleaning agent, electrostatic prevention agent and emulsifier.
For stripping can be in boiling dyeing bath or other preparation of stripping bath for stripping, the general dosage is 0.2 ~ 1g/L, or 1% ~ 5% of the weight of the fabric, acid media dye stripping, can be added to the stripping bath L % ~ 3% oxalic acid.
The diffusion and stability of the ice dye blue salt developing solution are improved after the addition of the additive, especially the scaling on the roller shaft of the developing groove can be reduced without staining the fabric.
