[0047] Polyethylene fibers were produced in the following manner. The oil-jacketed twin-helix mixer was filled with 6 wt% UHMWPE powder (GUR 4120, Ticona), 0.6 wt% antioxidant (tris(2,4-di-(tert)-butylphenyl)phosphate (Irgafos 168 , Ciba) and tetrakis-(methylene-(3,5-di-tert-butyl-4-phenylpropanoic acid))methane (Irganox 1010, Ciba), and 94.4% by weight mineral oil (Hydrobrite 1000, Sonneborn). The mixture was stirred and heated to 170° C. under nitrogen at 60 rpm until the UHMWPE was completely dissolved to prepare a spinning dope.
[0048] The spinning dope was then pumped through a 180-hole spinneret, and each hole of the spinneret had a diameter of 1 mm and 6 / 1 L / D. Throughput was 16 g / min and spin draw was 13. The extruded spinline was quenched through a water bath positioned 1 inch below the spinning spinneret. The gel filament yarn was wound onto a 4 1 / 8 inch diameter perforated plastic core.

[0052] Five polyethylene continuous 400 denier (364 dtex) multifilament yarns were obtained. Representative yarn properties are shown in Table 2. Yarn 1 is the yarn obtained from Example 1. Comparative Yarns A, B, & C are representative commercially available high tenacity and high modulus solvent spun high molecular weight polyethylene yarns. Comparative Yarn D is a representative low tenacity and low modulus melt spun low molecular weight polyethylene yarn.

[0055] The knitted fabric samples were made separately from each of the five filament yarns. Specifically, to facilitate acceptable knitting, all yarns were plied at both ends and twisted at 1.5 turns per inch (tpi) using a Saurer Allma twister. A Shima Seiki 13 standard glove knitting machine was used to produce approximately two meters of knitted fabric material with sufficient fibers to provide samples for subsequent cut tests and other evaluations. Glove samples were also knitted ...

[0061] The general procedure of Example 1 was repeated using appropriate spinnerets and spinning conditions to form polyethylene yarns of circular cross-section filaments of 200 and 1000 denier linear densities having a range of 1.1 to 3.9 dtex per yarn Individual filament linear density of filaments (1.0 to 3.5 denier per filament). The properties of these yarns are shown in Table 4.
