Abstract
The invention relates to a process for manufacturing a continuous yarn, and the product obtained from such process. A multiplicity of continuous filaments are formed by the mechanical drawing of a multiplicity of streams of molten thermoplastic(s) flowing from the orifices of at least one fiberizing device. A mixture, in the liquid state, is deposited on the surface of at least some of the filaments before they are brought together into at least one yarn. An absorbent mat may be continuously impregnated, with at least some of said mixture being continuously taken up by means of a rotating roller in contact with said mat, and using a sizing roller, said mixture may be deposited on the filaments while they are being drawn.
