Title:

HIGH STRENGTH POLYETHYLENE FIBER AND ITS USE

Document Type and Number:

WIPO Patent Application WO/2001/012885

Kind Code:

A1

Abstract:

A high strength polyethylene fiber which comprises a high molecular weight polyethylene having a recurring unit being substantially ethylene, has an average strength of 22 cN/dtex or more, and has the following property that a temperature rising DSC curve thereof shows at least one endothermic peak in a temperature region of 140 °C to 148 °C (low temperature side) and also at least one endothermic peak in a temperature region of 148 °C or higher (high temperature side), or alternatively, in the abrasion test substantially according to B method for measuring abrasion resistance in the test method for general purpose spun yarn (JIS L 1095), the frequency of friction until the break of the fiber is 100,000 or more; and the use of the fiber, for example, in cut fibers, lopes, nets, a bulletproof/protective clothing, a protective glove, a fiber-reinforced concrete product or a helmet.
