PURPOSE: To obtain a cloth having low free formaldehyde content and excellent shrink-proofness by crosslinking a rayon fiber cloth in a specific state and subjecting the cloth to low-temperature plasma treatment.

CONSTITUTION: A cellulosic fiber cloth, especially a rayon fiber cloth is immersed in a treating liquid containing a crosslinking agent (e.g. methylol-type resin), preferably a non-formaldehyde crosslinking agent and a catalyst, and dried in a state pressed in longitudinal direction with a compressive processing machine to effect the crosslinking reaction with the crosslinking agent. The crosslinked cloth is subjected to low-temperature plasma treatment to obtain the objective cellulosic fiber cloth having excellent shrink-proofness.
