Abstract
Processes for forming a yarn formed of i) high-performance polyethylene fibers including a hard component, the hard component having a Mohs hardness of at least 2.5, and ii) a polymeric resin, wherein the polymeric resin is a homopolymer of ethylene or propylene or is a copolymer of ethylene and/or propylene, wherein the polymeric resin has a density as measured according to ISO1183-2004 in the range from 860 to 970 kg/m3, a melting temperature in the range from 40 to 140° C. and a heat of fusion of at least 5 J/g.
Claims47
A method of manufacturing a multifilament yarn comprising filled high-performance polyethylene (HPPE)-based fibers, the method comprising the steps of:
- (a) providing HPPE-based fibers comprising HPPE filled with a hard component having a Mohs hardness of at least 2.5;
- (b) applying a solvent solution or an aqueous suspension of a polymeric resin to the fibers of step a), wherein the polymeric resin is a homopolymer of ethylene or propylene or is a copolymer of ethylene and/or propylene, wherein the polymeric resin has a density as measured according to ISO1183-2004 in the range from 860 to 970 kg/m3, a melting temperature in the range from 40 to 140° C. and a heat of fusion of at least 5 J/g;
- and
- (c) at least partially drying the solvent solution or aqueous suspension of the polymeric resin to obtain the yarn comprised of the filled HPPE-based fibers.
