DRAWN GEL-SPUN POLYETHYLENE YARNS AND PROCESS FOR DRAWING |
摘要 |
A polyethylene multi-filament yarn is provided, which comprises a polyethylene having an intrinsic viscosity in decalin at 135°C of from 5 dl/g to 35 dl/g, fewer than two methyl groups per thousand carbon atoms, and less than 2 wt. % of other constituents. The yarn has a tenacity of at least 17 g/d as measured by ASTM D2256-02. The filaments of the yarn have a peak value of the ordered-sequence length distribution function, F(L), as determined at 23°C from the low frequency Raman band associated with the longitudinal acoustic mode (LAM-1), at a straight chain segment length L of at least 40 nanometers. |
