ABSTRACT:
Fibers are made from thermoplastic polymers by supplying solid particles of the thermoplastic to a melting grid; heating the melting grid to a temperature sufficient to melt the thermoplastic; melting the thermoplastic particles on the heated melting grid such that the melted thermoplastic flows through the grid and is collected in a collecting chamber located beneath the melting grid; injecting into the collecting chamber below the melting grid an additive present in a non-aqueous carrier which carrier comprises organic rosin materials and a surfactant; without actuated mechanical stirring, forming a substantially homogeneous mixture from the injected additive; and extruding fibers from the substantially homogeneous mixture.
