Title:
高強度ポリエチレン繊維およびその利用
Document Type and Number:
Japanese Patent JP4141686
Kind Code:
B2
Abstract:
A ballistic material comprising high strength polyethylene fibers in which the fiber is characterized in that: it contains a high molecular weight polyethylene consisting essentially of a repeating unit of ethylene; it has an intrinsic viscosity number of 5 or larger and an average strength of 22 cN/dtex or higher; and the measurement of the fiber by differential scanning calorimetry (DSC) exhibits a temperature-increasing DCS curve having at least one endothermic peak over a temperature region of 140°C to 148°C (on the low temperature side) and at least one endothermic peak over a temperature region of 148°C or higher (on the high temperature side) or the number of frictions until the fiber is broken in an abrasion test according to method B for measuring abrasion resistance in the Testing Methods for Spun Yarn (JIS L 1095) is 100,000 or larger.
