FIBER HAVING CONTROLLED FIBER-BED FRICTION ANGLES AND/OR COHESION VALUES

摘要

The present invention relates to fiber having controlled dry fiber-bed friction angles and/or cohesion values. Controlling the dry fiber-bed friction angle and/or cohesion value of the fiber may allow control of the swelling of the material, the absorbency of the material, and/or the bending, buckling, porosity, and the compressibility and/or tension characteristics of the absorbent composite containing the fiber. The present invention relates to treatments for fiber to manipulate dry fiber-bed friction angle and cohesion value as well as new fiber materials having the desired dry fiber-bed friction angle and/or cohesion value characteristics. The present invention also relates to composites and products employing fibers have controlled dry fiber-bed friction values and/or cohesion values, alone or with other ingredients, including, for example, superabsorbent materials.
