  • Method for strengthening cellulosic substrates
    Patent number: 5427587
    Abstract: This invention relates to a method for strengthening a cellulosic substrate by treating the substrate with a formaldehyde-free curable aqueous composition and curing the composition. The cellulosic substrates include, for example, paper oil- and air-filter stock, rayon nonwoven wipes, cellulosic laminating stock, cotton woven fabrics, and wood flakes suitable to be consolidated into flakeboard.
