| 摘要 |
The present invention provides a terminal blocking processing agent of a polyester-based fiber structure allowing a treated product to efficiently take up a terminal blocking agent, and a method of producing a polyester-based fiber structure having hydrolysis-resistant properties using the terminal blocking processing agent, and is characterized in that terminal blocking treatment is carried out with the terminal blocking processing agent in which a carbodiimide-based terminal blocking agent and a carrier containing alkyl phthalimide and benzoate as essential components are emulsified or dispersed in water or a solvent using a surfactant. |
