FIELD: process engineering.
SUBSTANCE: invention relates to fabrication of synthetic fibrous materials, particularly polyamide yarns, fibers and threads and products thereof. Proposed method comprises spinning composition from melt containing, at least, one polyamide matrix wherein 0.01 to 5.0% by weight are dispersed. Note here that thread intake speed vs extrusion rate varies from 20 to 300. Aforesaid yarn, fibers or threads feature threshold strain of crosswise plasticity equal to 40 to 150 MPa and tensile elongation varying from 20% to 140%.
EFFECT: products comprising aforesaid yarn, fibers or threads represent felt for paper production machines, carpets, mats, cables, filtration fabrics etc.
