1. A method for treating a fabric, the method comprising the steps of contacting the fabric with a cationic polygalactomannan and preventing or recovering degradation of the fabric, wherein said cationic polygalactomannan contains non-ionic hydroxyalkyl substituents and has a Brookfield RVT viscosity at 25° C. and 20 rpm between 700 and 1,200 mPa·s, at a concentration of 1 wt % in water, wherein the cationic polygalactomannan is a hydroxypropyl guar hydroxypropyltrimonium chloride, and wherein preventing or recovering degradation of the fabric is evidenced by less fibrils in the fabric as compared to contacting the fabric with deionized (DI) water alone.
