Cotton fiber particulate and method of manufacture
View Patent ↗A cotton fiber particulate and method of manufacture including, generally, obtaining cotton fibers; mixing the cotton fibers with a solvent such as water to obtain a fiber furnish; milling the fiber furnish; and drying the fiber furnish to recover the cotton fiber particulate. Other steps include modifying the pH of the fiber furnish with a material such as calcium carbonate in an effort to make the fibers brittle, and filtering the fiber furnish to recover the cotton particulate. The fibers are milled to between 5-25 microns in length with a mean length of less than 50 microns with a mean length of 20 microns preferred.
1. A method of manufacture of a cotton fiber particulate, comprising:
obtaining cotton fibers;
mixing said cotton fibers with water to obtain a fiber furnish;
milling said fiber furnish to a mean fiber length of less than 50 microns;
drying said fiber furnish to recover the cotton fiber particulate.
2. The method of claim 1 wherein said mean fiber length is approximately 20 microns.
3. The method of claim 1 wherein said fiber furnish is filtered to obtain the cotton fiber particulate.
4. The method of claim 1 wherein the pH of the fiber furnish is modified through the introduction of calcium carbonate.
5. The method of claim 1 wherein said cotton fibers are virgin cotton fibers.
6. The method of claim 1 wherein said cotton fibers are reclaimed fibers derived from cotton waste.
7. The method of claim 6 wherein said reclaimed fibers are opened and cut.
8. A method of manufacture of a cotton fiber particulate, comprising:
obtaining cotton fibers;
mixing said cotton fibers with a solvent to obtain a fiber furnish;
milling said fiber furnish to a range of between approximately 5 and 25 microns;
filtering said fiber furnish to obtain cotton fiber particulate;
drying said cotton fiber particulate.
9. The method of claim 8 wherein said fiber furnish is milled to a mean of less than 25 microns.
10. The method of claim 9 wherein said fiber furnish is milled to a mean of approximately 20 microns.
11. The method of claim 8 wherein said solvent is water.
12. The method of claim 8 wherein the pH of the fiber furnish is modified with calcium carbonate.
13. The method of claim 8 wherein said cotton fibers are virgin cotton fibers.
14. The method of claim 8 wherein said cotton fibers are reclaimed fibers.
15. The method of claim 14 wherein said reclaimed fibers are opened and cut prior to mixing in a fiber furnish.
