ABSTRACT:
A composition for increasing the resistance of polyamide fibers or polyester fibers to oxidizing agents comprising an organosiloxane modified with amino groups, melamine formaldehyde resin, a catalyst for complexing the melamine formaldehyde resin and water. The composition is used by applying it to the fibers so the fibers absorb the composition, and then drying and curing the composition on the fibers. The composition is employed to treat a polyester or polyamide felt employed to convey wood pulp which is to be bleached, prior to paper making operations, treatment of the felt with the composition significantly lengthens the useful life of the felt, exposed to bleaching chemicals.
