| 发明名称 | Method for manufacturing high molecular weight polyethylene fibers | ||
| 摘要 | A process for manufacturing high molecular weight polyethylene fibers, including subjecting a polyethylene tape with a weight average molecular weight of at least 500,000 grams/mole, a 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 entire width of the tape. A polyethylene fiber having a Mw of at least 500 000 gram/mole, a Mw/Mn ratio of at most 6, and a 020 uniplanar orientation value of at most 55°. | ||

| 主权项 | 1. A process for manufacturing high molecular weight polyethylene fibers, comprising: forming a polyethylene tape with a weight average molecular weight of at least 500,000 grams/mole, a Mw/Mn ratio of at most 6, and a 200/110 uniplanar orientation parameter of at least 3 by subjecting a starting polyethylene to a stretching step in which a total stretching ratio applied is at least 80, and subjecting the polyethylene tape to a force in a direction of a thickness of the tape over an entire width of the tape. | ||
