Fiber and fiber sheet carrying solid particles

摘要

Process for manufacturing a fiber having at least a surface comprised mainly of a thermoplastic resin and carrying solid particles affixed to the surface, comprising the steps of: heating (50,51,52,53) the solid particles (29) having a melting point or a decomposition point higher than a melting point of the thermoplastic resin, to a temperature higher than the melting point of the thermoplastic resin, bringing the heated solid particles (29) into contact with the fiber (80,80') while maintaining the temperature of the heated solid particles (29) higher than the melting point of the thermoplastic resin to bond the solid particles (29) to a fiber (80,80') surface by fusing the fiber surface, and cooling the fused fiber (80,80') carrying the solid particle (29) to affix the solid particles (29) to the fiber (80,80') surface. Further, an apparatus of manufacturing the same, and a fiber having at least a surface comprised mainly of a thermoplastic resin and carrying solid particles affixed to the surface are also disclosed.
