Abstract
The invention relates to a net composed of a regular array of longitudinal ribbon-formed continuous filaments of a polymer substance, and a regular array of transverse stems of different polymer matter, said filaments being embedded in said stems, as well as to a process of producing such net from a sheet consisting of a regular array of longitudinal ribbon-like polymer filaments embedded in a polymer matrix, the filament polymer having a higher melting point than the matrix polymer, by transversely impressing said sheet at a temperature where said matrix is at least semi-molten and the filaments are solid, then splitting the structure.
