11. A nonwoven product comprising a fiber, wherein said fiber has increased fibrillation tendency and a wet abrasion resistance value (NSF value) of less than 45, wherein the fiber comprises cellulose and α(1→3)-glucan.
12. The non-woven product of claim 11 , wherein the fiber comprises between 1% and 99% by weight of said α(1→3)-glucan.
13. The non-woven product of claim 11 , wherein at least 90% of the α(1→3)-glucan are hexose units and at least 50% of the hexose units are linked via α(1→3)-glycosidic bonds.
14. The nonwoven product of claim 11 , wherein the α(1→3)-glucan has a weight-average degree of polymerization between 200 and 2000.
15. The nonwoven product of claim 14 , wherein the weight-average degree of polymerization is between 500 and 1000.
16. The nonwoven product of claim 11 , wherein said nonwoven product is a nonwoven fabric.
17. A paper product comprising a fiber, wherein said fiber has increased fibrillation tendency and a wet abrasion resistance value (NSF value) of less than 45, wherein the fiber comprises cellulose and α(1→3)-glucan.
18. The paper product of claim 17 , wherein the fiber comprises between 1 and 99% by weight of said α(1→3)-glucan.
19. The paper product of claim 17 , wherein at least 90% of the α(1→3)-glucan are hexose units and at least 50% of the hexose units are linked via α(1→3)-glycosidic bonds.
