Processes for making high-performance polyethylene multi-filament yarn are disclosed which include the steps of a) making a solution of ultra-high molar mass polyethylene in a solvent; b) spinning of the solution through a spinplate containing at least 5 spinholes into an air-gap to form fluid filaments, while applying a draw ratio DR.sub.fluid; c) cooling the fluid filaments to form solvent-containing gel filaments; d) removing at least partly the solvent from the filaments; and e) drawing the filaments in at least one step before, during and/or after said solvent removing, while applying a draw ratio DR.sub.solid of at least 4, wherein in step b) each spinhole comprises a contraction zone of specific dimension and a downstream zone of diameter Dn and length Dn with Ln/Dn of from 0 to at most 25, to result in a draw ratio DR.sub.fluid=DR.sub.sp*DR.sub.ag of at least 150, wherein DR.sub.sp is the draw ratio in the spinholes and DR.sub.ag is the draw ratio in the air-gap, with DR.sub.sp being greater than 1 and DR.sub.ag at least 1. High-performance polyethylene multifilament yarn, and semi-finished or end-use products containing said yarn, especially to ropes and ballistic-resistant composites, are also disclosed.

A label and related method of manufacture that includes a fabric made of yarn, in either cut individual singles or continuous ribbon format in any length. The yarn includes a fiber that has been recycled, that is recyclable, that is organic, that is biodegradable, and/or that can be derived from a material that is known to be environmentally friendly. The yarn, in one embodiment, may include a fiber defined as “high filament count” material, above the current industry standard of 24 filaments, being in the range of 72 to 96 to 144 filaments or higher per individual yarn, in any denier range of 30 denier to 150 denier thickness, in natural raw white, optical dyed white, or dyed colors. These yarns can be independent of each other.
