METHOD OF COMPLEX THREAD FROM HIGH-QUALITY POLYETHYLENE Russian patent published in 2013 - IPC D01F6/04 D01D4/02 A61L17/10 A61L17/04 F41H5/04

Abstract RU 2495969 C2

FIELD: metallurgy.

SUBSTANCE: thread is produced from polyethylene of super-high molecular weight with characteristic viscosity of 8-40 dl/g. Note here that said thread features creep rate defined at 70°C and 600 MPa equal to at most 5-10^-6s^-1. Complex thread produced from polyethylene of super-high molecular weight with characteristic viscosity of 8-40 dl/g containing 0.2-10 alkyl groups C₁-C₄ per 1000 atoms of C features creep rate defined at 70°C and 600 MPa equal to at most 3-10^-6s^-1. Invention covers also semi-finished articles including said thread, particularly, super-strong ropes, bullet-proof modules, medical implants.

EFFECT: better thread characteristics.
