Application description of fatty alcohol polyoxyethylene ether
Fatty alcohol polyoxyethylene ether (AEO), also known as alcohol ethers and alcohol ethoxylates, is the fastest growing and most widely ust.ed nonionic surfactan It has developed extremely rapidly in recent years and has partially replaced sodium alkylbenzene sulfonate, which is the main active substance of household detergents and an important variety of industrial surfactants. Mainly because AEO has excellent biodegradability and low temperature properties; it is not suitable for washing synthetic fibers without being affected by water hardness. It can be used in both powder formulations and liquid detergent formulations. The earliest application in the textile industry is nonionic surfactants, such as AEO, because nonionic surfactants have a variety of application properties, such as solubilization, cleansing, wetting, dispersibility, emulsifying and leveling. Therefore, it is widely used in the production process of natural fibers and synthetic fibers, and meets various requirements of the textile process. For example, higher fatty alcohol ethoxylates are the primary dye-dye leveling agents that retard the speed of dye-dyed fibers in dyeing and allow the dye to move from dark to light on the fibers, Avoid the phenomenon of unevenness and color spots, so it can be used as a leveling agent for direct, active, acidic and neutral dyes of various natural fibers. It can also be used as a leveling agent for vat dyes.
