Claims35
A method of making fiber from feathers, said method comprising:
- a) collecting raw feathers,
- b) washing said feathers in a polar water soluble organic solvent,
- c) carring out an additional washing step,
- d) removing solvent from said feathers, and
- e) removing fibers from the feather shafts of said feathers.
Fibers derived from feathers, wherein said fibers are prepared according to a method comprising
- a) collecting raw feathers,
- b) washing said feathers in a polar, water-soluble organic solvent,
- c) repeating said washing step,
- d) removing solvent from said feathers, and
- e) removing fibers from feather shafts;
- said fibers having been subjected to treatment to render them soft and pliable, wherein said treatment is beating or chemical treatment with redox reagents.
A method of making fiber pulp, said method comprising mixing fibers derived from feathers with an amount of water or wetting agents effective for the preparation of said fiber pulp, wherein said fibers are prepared according to a method comprising
- a) collecting raw feathers.
- b) washing said feathers in a polar, water-soluble organic solvent.
- c) repeating said washing step,
- d) removing solvent from said feathers, and
- e) removing fibers from feather shafts;
- said fibers having been subjected to treatment to render them soft and pliable, wherein said treatment is beating or chemical treatment with redox reagents.
A method of making fiber pulp, said method comprising mixing fibers derived from feathers with an amount of water and wetting agents effective for the preparation of said fiber pulp, wherein said fibers are prepared according to a method comprising
- a) collecting raw feathers,
- b) washing said feathers in a polar water-soluble organic solvent,
- c) repeating said washing step,
- d) removing solvent from said feathers, and
- e) removing fibers from feather shafts:
- said fibers having been subjected to treatment to render them soft and Pliable, wherein said treatment is beating or chemical treatment with redox reagents.
A composition comprising fibers derived from feathers and one or more additives, wherein said fibers are prepared according to a method comprising
- a) collecting raw feathers,
- b) washing said feathers in a polar, water-soluble organic solvent,
- c) repeating said washing step,
- d) removing solvent from said feathers and
- e) removing fibers from feather shafts;
- said fibers having been subjected to treatment to render them soft and pliable, wherein said treatment is beating or chemical treatment with redox reagents.
A composition comprising fiber pulp, wherein said fiber pulp comprises fiber derived from feathers and water or wetting agents, and wherein said fibers are prepared according to a method comprising
- a) collecting raw feathers,
- b) washing said feather in a polar, water-soluble organic solvent,
- c) repeating said washing step,
- d) removing solvent from said feathers, and
- e) removing fiber from feather shafts;
- said fibers having being subjected to treatment to render them soft and pliable, wherein said treatment is beating or chemical treatment with redox reagents.
A composition comprising fiber pulp, wherein said fiber pulp comprises fibers derived from feathers, water and wetting agents and wherein said fibers are prepared according to a method comprising
