POROUS POLYOLEFIN FIBERS Russian patent published in 2017 - IPC D01F6/46 A61F13/51 A61F13/53 A61L15/24 A61L15/42 

Abstract RU 2622431 C1

FIELD: chemistry.

SUBSTANCE: polyolefin fiber is formed from a thermoplastic composition comprising a continuous phase which contains a polyolefin matrix polymer and an nanoinclusion additive. The nanoinclusion additive is dispersed in the continuous phase as discrete nanoscale phase domains. When pulled, the nanoscale phase domains are able to interact with the matrix in a unique way creating a network of nanopores.

EFFECT: technique of porous structure creation in polyolefin fibers to provide a reduced density.
