Unocalchem’s new polyester polyether copolymerized hydrophilic finishing agent, due to the introduction of SIPM in its structure, its meta-structure destroys the regularity of the macromolecular structure, changes the planar structure of the benzene ring, and facilitates the intrusion of water molecules. The strong hydrophilic character of the sodium group increases the hydrophilic character of the finish, making it easier to disperse and dissolve in water.

The introduction of sodium sulfonate groups on the molecular chain of the new polyester fabric hydrophilic finishing agent causes electrostatic repulsion between the polymer molecules and between the molecular segments and the segments, preventing the mutual interaction between the polymer molecules and the polymer particles. Adjacent to agglomerate, increasing the stability of the aqueous solution or aqueous dispersion of the finish. Therefore, the problem of poor water solubility of the polyester polyether type hydrophilic finishing agent on the market is effectively solved, and the problem that the finishing agent is easy to aggregate during the process of immersing the polyester fabric and affecting the use effect thereof is improved.

Unocalchem ​​uses a self-made water-soluble new polyester polyether copolymerized hydrophilic finishing agent, uses a dipping method to finish the polyester fabric, optimizes the hydrophilic finishing conditions of the finishing agent, tests some application properties of the finished fabric, and compares with other domestic products. The application performance comparison was carried out. The influence of polyester hydrophilic finishing agent on the mechanical properties of the fabric was also investigated.

The results show that the optimum conditions for the immersion finishing of the finishing agent are: 4% (owf) of polyester hydrophilic finishing agent, 150°C baking temperature and 70s baking time; the hydrophilicity and antistatic property of the finished polyester fabric are obtained. Great improvement, good washability, and certain softness; to a certain extent, its application performance is better than domestic similar products, and the breaking strength of finishing fabrics is also improved.
