Ultra high molecular weight polyethylene multifilament yarn
The invention relates to a multifilament yarn containing n filaments, wherein the filaments are obtained by spinning an ultra-high molecular weight polyethylene (UHMWPE), said yarn having a tenacity (Ten) as expressed in cN/dtex of Ten(cN/dtex)=fn.sup.0.05dpf.sup.0.15, wherein Ten is at least 39 cN/dtex, n is at least 25, f is a factor of at least 58 and dpf is the dtex per filament.
Ultra high molecular weight polyethylene multifilament yarn
Process for spinning multifilament yarn containing n filaments are provided, wherein an ultra-high molecular weight polyethylene (UHMWPE) solution containing UHMWPE polymer and a solvent for the UHMWPE polymer are spun through n spin-holes of a spin plate and drawn before, during or after removal of the solvent to thereby obtain the multifilament yarn containing n filaments, the yarn having a tenacity (Ten) as expressed in cN/dtex of Ten(cN/dtex)=fn.sup.0.05dpf.sup.0.15, wherein Ten is at least 39 cN/dtex, n is at least 25, f is a factor of at least 62.0 and dpf is the dtex per filament.
