ABSTRACT OF THE DISCLOSURE A process is provided herein for the immobilization of an enzyme on the surface of cotton cloth. The cotton cloth so provided is also novel. The process comprises treating the cloth with a chemi- cal agent e.g. polyethylenimine to provide an ionic surface thereon; adsorbing the enzyme, e.g. invertase on that surface by ionic inter- action; and immobilizing the adsorbed enzyme on the cloth by cross- linking with a cross-linking agent, e.g. glutaraldehyde. The enzyme immobilized on the cloth by this technique exhibits good activity and stability.
