Abstract: Water soluble polyamides which are obtained by reacting aliphatic polyamines with Alpha , Beta -unsaturated aliphatic monocarboxylic acids or aliphatic polycarboxylic acids optionally containing hetero atoms or their functional derivatives capable of forming amides are used as agents for preventing damage to protein-containing fiber materials or mixtures of such materials by adding the polyamides to an acidic aqueous medium used to treat said fibers.
