Abstract

Multi-filament UHMW PE yarns can be produced according to processes that result in improved properties. The UHMW PE can have an intrinsic viscosity in decalin at 135 °C of at least about 30 dl/g, and can be processed under optimal conditions to achieve a gel spun yarn having a tenacity of greater than about 45 g/d (40.5 g/dtex).

Claims (10)

1. A processes for producing gel spun yarn made from ultra high molecular weight polyethylene (UHMW PE), the process comprising the steps of:
feeding a slurry that comprises an UHMW PE and a spinning solvent to an extruder to produce a liquid mixture, the UHMW PE having an intrinsic viscosity in decalin at 135°C of at least 30 dl/g;

passing the liquid mixture through a heated vessel to form a homogeneous solution comprising the UHMW PE and the spinning solvent;

providing the solution from the heated vessel to a spinneret to form a solution yarn;

drawing the solution yarn that issues from the spinneret at a draw ratio of from 1.1:1 to 30:1 to form a drawn solution yarn;

cooling the drawn solution yarn to a temperature below the gel point of the UHMW PE polymer to form a gel yarn;

drawing the gel yarn in one or more stages at a first draw ratio DR1 of from 1.1:1 to 30:1;

drawing the gel yarn at a second draw ratio DR2;

removing spinning solvent from the gel yarn in a solvent removal device to form a dry yarn;

drawing the dry yarn at a third draw ratio DR3 in at least one stage to form a partially oriented yarn;

transferring the partially oriented yarn to a post drawing operation; and drawing the partially oriented yarn at a post drawing temperature in the post drawing operation to a fourth draw ratio DR4 of from 1.8:1 to 15:1 to form a highly oriented yarn product having a tenacity of greater than 45 g/d (40.5 g/dtex) and a modulus of greater than 1400 g/d.
2. The processes for producing gel spun yarn of claim 1, wherein the partially oriented yarn is produced in a continuous in-line process and the post drawing operation is a discontinuous step that is separate from the in-line process.
3. The processes for producing gel spun yarn of claim 1, wherein the UHMW PE has average particles size from 100 microns to about 200 microns and about 90% of the particles have a particle size that is within 40 microns of the average particle size.
4. The processes for producing gel spun yarn of claim 3, wherein the UHMW PE has an intrinsic viscosity of greater than 30 dl/g, and the partially oriented yarn has an intrinsic viscosity of greater than 17 dl/g.
5. The processes for producing gel spun yarn of claim 1, wherein the solution comprises the UHMW PE in an amount from 6% by weight to 10% by weight of the solution.
6. The processes for producing gel spun yarn of claim 1, wherein the spinning solvent is selected from the group consisting of mineral oil, decalin, and mixtures thereof.
7. The processes for producing gel spun yarn of claim 1, wherein the partially oriented yarn (POY) has a tenacity from 12 g/d (10.8 g/dtex) to 25 g/d (22.5 g/dtex).
8. The processes for producing gel spun yarn of claim 1, wherein the drawing rate of the drawing of the post drawing operation is a constant value when the partially oriented yarn is at the post drawing temperature.
9. The processes for producing gel spun yarn of claim 1, wherein the drawing profile of the post drawing operation is a straight line when the partially oriented yarn is at the post drawing temperature.
10. A ballistic article made from a gel spun yarn produced in accordance with the processes for producing gel spun yarn of claim 1.
