A method for providing a treated cellulose-comprising mixed starting material (110), in particular a mixed starting material (110) for forming a, in particular regenerated, cellulosic molded body (102) is described. The method comprises: i) providing (10) a first starting material (101a) which comprises a lignocellulosic raw material, ii) providing (1) a second starting material (101b) which comprises a cellulose-containing lignin-free product, iii) mixing (15) the first starting material (101a) and the second starting material (101b) to a mixed starting material (101), and iv) at least partially commonly treating (20) the first starting material (101a) and the second starting material (101b) for obtaining the treated mixed starting material (101), in particular a mixed pulp.

A composition and process for making the composition by co-refining: fibrillated virgin cellulose fibers, waste/recycle cellulose fibers, or both; co-refined cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3 and the weight percent of CE staple fibers is less than 30 wt. %, based on the weight of CE staple fibers and said cellulose fibers; and water. The composition can be co-refined to obtain lower Canadian standard freeness yet improved drainage and wet laid products having good tensile strength, air permeability, stiffness, burst strength, and bulk.
