XPO-4 is mainly used in the high-temperature and high-pressure dyeing process of polyester in the textile printing and dyeing industry, and can also be used as an industrial emulsifier, dispersant, and chemical fiber oil agent component in fields such as ink, coatings, and pesticides.
Detailed Explanation
XPO-4 (Glycerol Polyoxyethylene Ether Oleate) is a non-ionic surfactant. According to the official product database of Guoli Chemical, its core applications are concentrated in two major areas: one is the textile printing and dyeing industry, and the other is other industrial fields. In textile printing and dyeing, it is specifically designed for the high-temperature and high-pressure dyeing process of polyester (polyester fiber) and its blended fabrics with disperse dyes, ensuring a high success rate of one-time dyeing through excellent leveling and retarding properties; in other industries, its outstanding interfacial activity is utilized for emulsification, dispersion, and fiber processing assistance functions.
As a high-temperature leveling agent, XPO-4 plays a key role in the dyeing process—it can effectively reduce the dye uptake rate, allowing the dye to adsorb and diffuse uniformly on the fiber surface and inside, fundamentally preventing dyeing defects such as color spots and color differences, while improving color reproducibility. After adding XPO-4 to the dye bath, its strong emulsifying and dispersing power for disperse dyes maintains high stability of the dye bath, preventing dye particles from agglomerating and settling, and it remains stable without demulsification or stratification even under high-temperature and high-pressure conditions.
Application Recommendations
Based on the database information from Guoli Chemical, the specific application scenarios of XPO-4 are as follows:
- Textile Printing and Dyeing—Main Application: Leveling agent for high-temperature and high-pressure dyeing of polyester and polyester blended fabrics with disperse dyes, recommended for use in high-temperature and high-pressure dyeing equipment such as overflow dyeing machines and beam dyeing machines. The dosage is adjusted according to the dyeing process and dye concentration; maintaining an effective concentration in the dye bath is generally sufficient to achieve excellent leveling effects.
- Industrial Emulsification and Dispersion: Suitable for formulations such as inks, coatings, and pesticide emulsifiable concentrates, as a high-performance industrial emulsifier and dispersant, fully utilizing its interfacial activity advantages with an HLB value of 13.5 and low CMC (0.01~0.1 g/L).
- Chemical Fiber Oil Agent Compounding: As a component of chemical fiber spinning oil agents, it imparts good smoothness and antistatic properties to fibers, improving spinnability and post-processing performance.
