Fibers with filler

1. An article of manufacture comprising:

a binder and a filler, the binder being cellulose nanofibrils and PVOH, and the filler being deinking waste solids comprising ash and cellulose fines;

wherein the article is a fiber or a film, and the cellulose nanofibrils and PVOH impregnate or encapsulate the deinking waste solids to form the fiber or the film, and the PVOH is present an amount in a range between about 20 wt. % to about 99 wt. % based on the total weight of the article.

2. The article of claim 1 , wherein the filler is present in a range between about 1 wt. % to about 80 wt. % based on the total weight of the fiber.

3. The article of claim 1 , wherein the cellulose nanofibrils are present in a range between about 1 wt. % to about 80 wt. % based on the total weight of the article.

4. The article of claim 1 , wherein the ash is precipitated calcium carbonate, ground calcium carbonate, gypsum, titanium dioxide, clay, silica, or any combination thereof.

5. The article of claim 1 , wherein the filler comprises particles having an average size of less than about 20 micrometers in diameter.

6. The article of claim 1 , further comprising a processing aid.

7. The article of claim 6 , wherein the processing aid is present in a range between about 0.5 wt. % to about 10 wt. % based on the total weight of the fiber.

8. The article of claim 6 , wherein the processing aid is carboxymethylcellulose, starch, glyoxal, glutaraldehyde, dialdehydes boric acid carbonate, zirconium ammonium carbonate, glyoxalated polyacrylamide, polyamide-epichlorohydrin, polyamine-epichlorohydrin, urea-formaldehyde, melamine-formaldehyde, polyethyleneimine, propylene glycol, diethylene glycol, triethylene glycol, dipropylene glycol, glycerol, or any combination thereof.

9. A paper web comprising the article of claim 1 , wherein the article is the fiber.

10. The article of claim 1 , wherein the PVOH has a degree of polymerization in a range between about 500 to about 3,000.

11. The article of claim 10 , wherein the degree of polymerization is in a range between about 1,000 to about 1,600.

12. The article of claim 11 , wherein the PVOH has a degree of hydrolysis of greater than about 95%.

13. The article of claim 12 , wherein the PVOH has a degree of hydrolysis of greater than about 98%.

14. A paper web comprising:

a cellulosic substrate having a surface; and

a fiber impregnating the cellulosic substrate and having an average diameter in a range between about 1 micrometer and about 80 micrometers;

wherein the fiber comprises a binder and a filler, the binder being cellulose nanofibrils, and the filler being deinking waste solids comprising ash and cellulose fines, the cellulose nanofibrils impregnating or encapsulating the deinking waste solids.

15. The article of claim 14 , wherein the filler is present in the fiber in a range between about 5 wt. % to about 50 wt. % based on the total weight of the fiber.

16. A method of making an article of manufacture, the method comprising:

impregnating or encapsulating a binder with a filler to form a filler impregnated binder or a filler encapsulated binder, the filler being deinking waste solids comprising ash and cellulose fines, and the binder being a PVOH and cellulose nanofibrils; and

preparing an extrudable dope from the filler impregnated binder or the filler encapsulated binder;

wherein the article is a fiber or a film and the PVOH is present an amount in a range between about 20 wt. % to about 99 wt. % based on the total weight of the article.

17. The method of claim 16 , further comprising wet spinning, dry spinning, shear spinning, or slit extruding the extrudable dope to form the fiber or the film.

18. The method of claim 16 , wherein the cellulose nanofibrils are at least one of a cellulose nanofibril or a cellulose fibrid.

19. The method of claim 16 , further comprising homogenizing wood pulp fibers or other fibrillatable cellulose to form the cellulose nanofibrils.
