The fatty alcohol polyoxyethylene ether has a melting point of 41-45 ° C, and is easily soluble in water, ethanol, ethylene glycol, etc., and has a cloud point. It is resistant to acids, alkalis, hard water, heat, heavy metal salts, easy to biodegrade, and less foam. It has strong leveling, retarding, penetrating and diffusing properties for various dyes. It has the performance of scouring and can be used in the same bath as various surfactants and dyes. The number of ethoxy groups in the fatty alcohol polyoxyethylene ether molecule can be artificially adjusted during the synthesis process to prepare a series of nonionic surfactants with different properties and uses. Low toxicity, stored in a cool, ventilated, dry place, transported as normal chemicals.
1 as a diffusing agent. It prevents the decomposition products of some sodium-frozen dyes from accumulating on the fabric and contaminating the chromaticity.
2 to do direct dye dyeing cotton leveling agent. Add 0.2~0.5g/L to the solution.
3 to do vat dye dyeing cotton leveling agent. The general dosage is 0.02~0.1g/L.
4 to do acid complex dye dyeing wool products leveling agent. The addition of leveling agent O is 1% to 3%, the amount of sulfuric acid can be reduced from 4.7% to 9.2% to 4.3% to 5.8%, and the pH value (dyeing bath) can be increased from 1.9 to 2.1 to 2.2 to 2.4. At this time, the initial dyeing speed is less increased, the dyeability is improved, and the percentage of dyeing at the end of dyeing is less affected. The dyeing bath can be added after dyeing for a period of time, so that the initial dyeing speed is not increased by the addition of the flattening plus O. Pingping plus O can be used together with Yuanming powder. Yuanming powder can reduce the initial dyeing speed and improve the transferability.
5 to do disperse dye dyed elastic nylon silk leveling agent. The general dosage is 1%~4%.
