The present invention pertains to a process for manufacturing high molecular weight polyethylene fibers, comprising subjecting a polyethylene tape with a weight average molecular weight of at least 500 000 gram/mole, an Mw/Mn ratio of at most 6, and a 200/110 uniplanar orientation parameter of at least 3 to a force in the direction of the thickness of the tape over the whole width of the tape. The invention also pertains to a polyethylene fiber having an Mw of at least 500 000 gram/mole, an Mw/Mn ratio of at most 6, and a 020 uniplanar orientation value of at most 55°. The use of these fibres in various applications is also claimed. The preparation of low-linear density fibers is particularly preferred. |
