| titleOfInvention |
Polyurethane fibers and films |
| abstract |
This invention provides a fiber comprising a wet- or dry-spun product, or a film, which comprises a polyurethane and layers delaminated from a lamellar clay, said layers being dispersed in said polyurethane, an a process for producing such fibers or film comprising the steps of: (a) contacting a solution comprising a polyurethane and an aprotic polar solvent with a lamellar clay, or with a dispersion of said lamellar clay in the aprotic polar solvent, to form a polyurethane/clay dispersion; (b) agitating the polyurethane/clay dispersion sufficient to delaminate all or a portion of said layers from the lamellar clay and from each other; and (c) wet- or dry-spinning the polyurethane/clay dispersion to form a fiber (or solution casting and drying the polyurethane/clay dispersion to form a film). Fiber and film produced by the processes of the present invention exhibit reduced tack and an increased ability to affix at least one dye. |
