According to the present invention, there are provided a novel partial ester of a nitrogenous carboxylic acid ester with cellulose, the partial ester being useful as an antibacterial agent, a flame retardant, etc., and a simple and convenient process for preparing the same. Fibers made of said partial ester have washing-resistant antibacterial property and flame retardancy.
There can be prepared the partial ester of a nitrogenous carboxylic acid ester with cellulose by contacting a nitrogenous carboxylic acid ester with cellulose and heat-treating the mixture.
