Abstract

See full text

The present invention relates to means for manufacturing micro-beads (polymer micro-particles) comprising thermoplastic polymer and having the average particle size of 10 μm or less, and extending into the nano-range. An original filament comprising a thermoplastic polymer is passed through an orifice under an air pressure (P1) and guided to a spray chamber under a pressure (P2; where P1>P2). The original filament having passed through the orifice is heated and melted under irradiation by an infrared beam, and is sprayed in microparticulate form from the orifice by the flow of air generated by the pressure differential between P1 to P2, whereby micro-beads comprising thermoplastic polymer micro-particles having an average particle size of 10 μm or less, and even less than 1 μm are manufactured.
