  • Publication number: 20230071802
    Abstract: A ply fibrous product comprises at least one ply selected from a nonwoven ply and a tissue paper ply, wherein the at least one ply selected from a nonwoven ply and a tissue paper ply comprises cellulosic fibers comprising an organic polycarboxylic acid and wherein the organic polycarboxylic acid has at least one carboxyl group covalently bound to the cellulosic fibers and at least one free carboxyl group. Due to the presence of covalent chemical bonds between a carboxyl group of the polycarboxylic acid and hydroxy groups of the cellulosic fibers present in all substrates, the ply fibrous products display a long-lasting acidic pH even after having been rinsed with water. In some embodiments a long-lasting acidic pH may be achieved in the nonwovens treated with an organic polycarboxylic acid even after washing with a washing detergent.
