Abstract
A fiber having a surface with a relatively low coefficient of friction portion and a relatively high coefficient of friction portion. The fiber may be produced by slitting a film/sheet which has been coextruded, laminated and/or coated, or by partially coating a base fiber. Fabrics made from such fibers exhibit increased structural integrity.
Claims9
A method of producing a fiber, comprising the steps of:
- coating a sheet of material to form a coated sheet, said coated sheet having at least a first outer layer, a second outer layer, and a center layer;
- wherein said center layer is made up of a material having a higher coefficient of friction than the material making up at least one of said outer layers;
- and
- orienting and slitting the coated sheet to form fibers, such that the top surface of said fibers are made up of the same material as said first outer layer, the bottom surface of said fibers are made up of the same material as said second outer layer, the side surfaces of said fibers are made up of the same material as said center layer, and the side surfaces of said fibers have a coefficient of friction that is 1.10 to 5.00 times the coefficient of friction of at least one of said top surface of said fibers and said bottom surface of said fibers.
