Abstract
The present invention relates to a novel process for the manufacture of nonwoven surfaces. It relates more particularly to a process for the manufacture of nonwoven surfaces by the process of direct melt spinning of continuous filaments arranged in the form of a sheet. This process employs a composition based on a thermoplastic polymer exhibiting an electrical conductivity sufficient to prevent the formation of electrostatic charges or to allow their removal during the spinning process.
