Abstract: The present invention relates to a deinking composition and a method of deinking wastepaper by using a mixture of enzymes that act on constituents of all three waste paper components involved in ink retention on final pulp. The first component represents substrates located on the surface and in the internal waste paper structure. The second component represents substrates located in the interface between paper and ink, usually formed by coatings or size-press (starch containing or not) applied layers. The third component represents substrates located in the ink and/or toner compounds. This method provides improved performance in relation to conventional methods, or current deinking with enzymes, which acts on a limited number of substrates involved in ink retention on final pulp.

Abstract: An organic agent for enhancing opacity in paper, paperboard or pulp comprises a hydrolase or an oxido-reductase; this enzymatic opacifying agent overcomes drawbacks associated with traditional organic and inorganic opacifying agents but also serves to provide increased strength and reduced porosity in paper and paperboard.

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.
