Abstract

A particle or particles of cellulosic wood pulp fibers having a top and bottom face and a hexagonal perimeter, and methods of using it.

Claims (13)

1. A method of combining wood pulp fibers with a material, the method comprising:

providing wood pulp fiber particles having two opposed faces and a hexagonal perimeter, a major axis length of 4 to 8 mm, a width of 2 to 5 mm and a thickness of 0.1 mm to 4 mm,

metering the particles through a feeder to a mixer,

forming fibers, fiber bundles or a mixture thereof from the particles before or during the mixing, and

mixing the fibers, fiber bundles or mixture thereof with a material to form a blend of the fibers, fiber bundles or mixture thereof and the material.

2. The method of claim 1 wherein the material is a thermoplastic resin.

3. The method of claim 1 wherein the material is cement.

4. The method of claim 1 wherein the material is a thermoset resin.

5. The method of claim 1 wherein the material is a dry constituent having a higher bulk density than the fiber to produce a blend with a bulk density lower than the bulk density of the dry constituent.

6. The method of claim 1 wherein the material is a dry constituent having a lower bulk density than the fiber to produce a blend with a bulk density higher than the bulk density of the dry constituent.

7. The method of claim 1 wherein the material is a dry constituent having a lower absorbent capacity than the fiber to produce a blend with a higher absorbent capacity than the dry constituent.

8. The method of claim 1 wherein the material is a dry constituent having a higher absorbent capacity than the fiber to produce a blend with a lower absorbent capacity than the dry constituent.

9. The method of claim 1 wherein the material is a dry constituent having a lower absorbency rate than the fiber to produce a blend with a higher absorbent absorbency rate than the dry constituent.
