Abstract
Compositions are disclosed suitable as biobased and compostable binders for fiber-based materials, paper, textiles, woven and nonwoven materials. The compositions are adjusted to a pH<7 and comprise a water soluble biobased polymer or a protein hydrolysate, a support agent selected from at least one in the group of saccharides and polyols, and tannic acid. Also disclosed is fiber-based materials, paper, textiles, woven and nonwoven materials treated with the compositions and methods for such treatment.
Claims21
A composition suitable as a binder for fiber-based materials, paper, textiles, woven and nonwoven materials, comprising:
- a water soluble biobased polymer or a protein hydrolysate;
- a support agent selected from at least one in the group of saccharides and polyols;
- tannic acid;
- a pH adjuster, providing a resulting aqueous composition with a pH of less than 7;
- and
- wherein the support agent is one or more of a polyols selected from glycerol, mannitol, maltitol, xylitol and sorbitol saccharides selected from glucose, mannose, fructose, sucrose, sucralose, sucrose esters, cyclodextrin, hydrolysed starch, dextrin.
(canceled)
A method of treating fiber based materials, paper, textiles, woven and nonwoven materials with a composition as a binder,
- the composition comprising:
- a water soluble biobased polymer or a protein hydrolysate;
- a support agent selected from at least one in the group of saccharides and polyols;
- tannic acid;
- and
- a pH adjuster, providing a resulting aqueous composition with a pH of less than 7;
- and
- wherein the support agent is one or more of a polyols selected from glycerol, mannitol, maltitol, xylitol and sorbitol saccharides selected from glucose, mannose, fructose, sucrose, sucralose, sucrose esters, cyclodextrin, hydrolysed starch, dextrin;
- the method comprising:
- (a) applying the composition to a fiber based material, a paper, a textile, a woven or a nonwoven material;
- (b) curing the applied material at a temperature above ambient (room) temperature, but below 200° C.
