XPO-4 (Glyceryl Polyoxyethylene Ether Oleate) is a high-performance nonionic surfactant developed by GuoLi Chemical. Its core application positioning is as a high-temperature and high-pressure leveling agent for polyester and its blended fabrics. In the high-temperature and high-pressure dyeing process with disperse dyes, this product effectively regulates the dye uptake rate through excellent migration and retardation capabilities, enabling uniform adsorption and diffusion of dyes on and inside the fiber surface. This fundamentally prevents dyeing defects such as color patches, color differences, and spots, significantly improving the one-time dyeing success rate and shade reproducibility.
In addition to dyeing processes, XPO-4, leveraging its outstanding interfacial activity and emulsifying/dispersing abilities, can be widely used in the industrial emulsifier and dispersant fields, such as in formulations for inks, coatings, and pesticide emulsifiable concentrates, effectively stabilizing emulsions and preventing particle agglomeration and sedimentation. Meanwhile, this product is also used as a component in chemical fiber spinning oil formulations, imparting good smoothness, cohesion, and antistatic properties to fibers, thus improving the spinnability and subsequent processing performance of chemical fibers.
| Application Industry | Specific Process/Use | Functional Role |
|---|---|---|
| Textile Printing & Dyeing | High-temperature and high-pressure dyeing of polyester with disperse dyes | High-temperature leveling agent, retarder |
| Textile Printing & Dyeing | Dyeing of polyester blended fabrics | Prevents color patches and differences, improves leveling |
| Inks/Coatings | Preparation of emulsions and dispersion systems | Industrial emulsifier, dispersant |
| Pesticide Formulations | Formulation of pesticide emulsifiable concentrates (EC) | Emulsifier component |
| Chemical Fiber Manufacturing | Spinning oil formulation compounding | Smoothing agent, antistatic agent component |
In high-temperature and high-pressure dyeing processes, XPO-4 is recommended to be added during the dye bath preparation stage. Its excellent emulsifying and dispersing power ensures that disperse dyes are uniformly suspended in the dye bath, reducing the risk of dye particle aggregation at high temperatures. Its outstanding resistance to acid, alkali, and hard water ensures stable performance under different water qualities and process conditions, without demulsification or delamination under high-temperature working conditions. When used as an emulsifier or oil agent component, it is recommended to determine the optimal dosage through experiments based on the specific formulation system and HLB value requirements.
