ABSTRACT:
The production of pile fabric, comprising the use of a compound of two or more azilidine groups or two or more blocked isocyanate groups in one molecule, with a polyurethane solution as a binding agent is disclosed. The binding strength of the binding agent is not affected by high-temperature, high-pressure jet-dyeing or the solvent used in dry-cleaning. There is no loss of quality as a result of pile fall-out during such processes.
