PCT No. PCT/FI93/00230 Sec. 371 Date Dec. 16, 1994 Sec. 102(e) Date Dec. 16, 1994 PCT Filed May 28, 1993 PCT Pub. No. WO93/24686 PCT Pub. Date Dec. 9, 1993.The invention concerns a high strength polyethylene fibre, which is prepared by melt spinning polyethylene having a high density through a spinnerette, by cooling the fibre coming out from the spinnerette and by stretching the fibre obtained at 50 DEG -150 DEG C. The polyethylene used in the melt spinning is a homopolymer of ethylene having a weight average molecular weight Mw between 125000-175000 g/mol, a number average molecular weight Mn between 26000-33000 g/mol, polydispersity (Mw/Mn) below 5 and the density higher than 955 g/dm3. The stretching degree in the drawing step is at least 400%. |
