FIELD: natural and chemical threads and fibers.
SUBSTANCE: method of manufacturing precursors for orientational stretching of film threads from ultrahigh molecular weight polyethylene – UHMWPE refers to the initial stage of manufacturing high-strength high-modulus film filaments from the specified polymer by carrying out orientational stretching of the inventive precursors. Method of manufacturing precursors for orientational stretching of film filaments from ultrahigh molecular weight polyethylene includes: selection of UHMWPE reactor powder by morphological properties; compaction of UHMWPE reactor powder at room temperature with a degree of compression deformation – ratio of sample thicknesses before and after completion of compaction Θ = Sstarts/Sends = 2.0–2.2; monolitization of compacted UHMWPE reactor powders at temperature of 130–135 °C.
EFFECT: inventive method is characterized by high processability and does not require technologically complex and energy-consuming devices for its implementation.
