Abstract: A treating agent for cellulosic textile materials includes a water-soluble phosphonium salt of phosphorus-containing oxoacid and polycarboxylic acid as active ingredients, and a process of treating cellulosic textile materials uses the treating agent. The treating agent eliminates the necessity of the use of a substance releasing formaldehyde during wash and wear treatment and enables non-formaldehyde wash and wear treatment, and the cellulosic textile material treated by the treating agent is completely free from formaldehyde, retains enough of the strength thereof, and undergoes neither discoloration nor fibrillation.
