CA 2206020

Fiber produced from high density (>0.940 g/cm3) polyethylene resins. The resins have a MWD less than 3.6, a melt index in the range from 4 to 1000, and a Mz/Mw ratio less than 2.2. Both homopolymers and copolymers of ethylene may be used in this invention. The fibers may be formed by the spunbonded, meltblown or melt spinning processes and may be used to form fabrics and garments.

La présente invention concerne une fibre fabriquée à partir de résines de polyéthylène à densité élevée (>0,940 g/cm?3¿). Ces résines ont une répartition de masse moléculaire (MWD) inférieure à 3,6, un indice de fusion appartenant à la gamme de 4 à 1000, et un rapport M¿z?/M¿w? inférieur à 2,2. Conformément à cette invention, il est possible d'utiliser à la fois des homopolymères et des copolymères d'éthylène. Les fibres peuvent être obtenues par les procédés de production de non-tissé, de fusion-soufflage ou de filage par fusion et peuvent servir à la fabrication de tissus et de vêtements.
