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

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, buckli...

Beschreibung
Zusammenfassung:	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. L'invention porte sur des fibres produisant des lits de fibres sèches à angle de frottement et/ou niveaux de cohésion variables. En agissant sur lesdits angles et lesdites valeurs, on peut également influer sur le gonflant du matériau et son pouvoir absorbant, ainsi que sur les caractéristiques de flexion, flambage, porosité, compressibilité et/ou tension d'un composite absorbant contenant lesdites fibres. L'invention porte également sur des traitements desdites fibres permettant d'agir sur lesdits angles et lesdites valeurs, sur de nouveaux matériaux à base de fibres présentant lesdits angles et lesdites valeurs désirés, et sur des composites et produits à base de telles fibres, associées ou non à d'autres ingrédients, et qui peuvent par exemple être des matériaux superabsorbants.
