According to an example aspect of the present invention, there is provided a process for the conversion of cellulosic waste material into a recycled cellulose product comprising the steps of cooking the waste material in a cooking liquor to remove lignin from the waste material and provide a delignified pulp, dissolving the delignified pulp in an ionic liquid to provide a spinning dope suitable for dry jet-wet spinning in an ionic liquid solution, and subjecting the spinning dope to a further processing step to provide a recycled cellulose product, said further step selected from the group of spinning cellulose fibers for use in textiles from the solution, extruding a film product for use in packaging, regenerating the dope as a hydrogel and regenerating the dope as an aerogel.

Disclosed is a method of obtaining regenerated cellulose fiber by using supercritical-N.sub.2O and/or supercritical-CHF.sub.3 compounds from cotton straw which are formed as thin chips mechanically.

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.

A method for producing a microbial cellulose pulp for the production of viscose dope, the method comprising the step of: exposing a microbial cellulose to a volume of water to form the microbial cellulose pulp for the production of viscose dope, wherein the cellulose concentration in the microbial cellulose pulp is less than 0.040 g of cellulose per mL of pulp.

The present invention relates to a method for producing a nonwoven fabric. The method according to the invention comprises forming a nonwoven web using a wet lay forming process, hydroentangling the web and providing the web with a high quality hydroembossed pattern. The invention also concerns a nonwoven fabric exhibiting a three dimensional pattern, which remains even in wet wipes prepared from the material.

The present invention provides a wet-pressed, wet-laid tissue product that is soft and durable. The tissue product includes regenerated cellulose fibers providing 25% or less of the total weight of the wet-laid tissue product. The tissue product can include a DSF value of greater than 1.22. The DSF value is defined by the equation: DSF=(Durability Value/TS7 Softness value)/number of plies of the wet-pressed, wet-laid tissue product.
