| titleOfInvention | low creep fiber |
| abstract | The present invention relates to a method for preparing gel-spun UHMWPE fibers, the method comprising the steps of: providing an intrinsic viscosity (IV) of at least 8 dl/g, a comonomer content (C BR ) of at least 0.05 SCB/1000TC, An ultra-high molecular weight polyethylene composition having a comonomer mass average distribution (C MAD ) of at least 0.05, wherein the comonomer has at least 4 carbon atoms; the composition is dissolved in a solvent to form a UHMWPE concentration of 2- 40 wt% polymer solution; spinning the polymer solution through a porous template to form solution fibers; cooling the solution fibers to below 80° C. to form gel fibers; drawing the fibers in at least one step to form drawn fibers; At least a portion of the solvent is removed before, during, or after stretching, wherein the ratio of C MAD to C BR is greater than 1.0. The present invention also relates to gel-spun UHMWPE fibers obtainable by this method and products comprising said gel-spun UHMWPE fibers. |
