Manufacture of bonded textile sheet structures

A process for the manufacture of bonded textile sheet structures which comprises applying:

• a. a solution or an aqueous dispersion of a binderpolymer;
• and
• b. from 6 to 40 percent by weight, based on the textile web structure, of a .beta.-aziridino propionic acid ester or aziridino succinic acid ester or both of an ethylene oxide adduct with water or with a compound which is at least bifunctional containing OH, NH.sub.2 or NH groups and containing from 2 to 6 carbon atoms, and in which the number of ethylene oxide units per functional group in said adduct is from 3 to 50, to a textile sheet structure and solidifying the polymer by drying the impregnated structure at elevated temperatures, followed by fixation of the aziridino compounds on the textile web structure in the presence of 3 to 40% by weight, based on the aziridino compounds, of an organic polymer with a K value of from 15 to 100 containing at least 3% by weight of the polymer of carboxyl, hydroxyl, NH.sub.2 or NH groups as crosslinkers.
