Claims
- 1. A method for producing an applicator for makeup use comprising:
- preparing an elongated bundle of fibers of a predetermined length having a core portion consisting of a plurality of straight fibers and a sheath portion wrapped around said core portion consisting of crimped thermoplastic fibers adhering partially to each other;
- removing a longitudinal section of said fibers of said sheath portion at one end of said bundle from about said fibers of said core portion to expose an end portion of said fibers of said core portion;
- applying heat and pressure to said thermoplastic fibers over a region adjacent said exposed end portion of said core portion to heat-soften, radially compact, and bond together the thermoplastic fibers in said region about said core fibers.
- 2. A method for producing an applicator for makeup use comprising:
- preparing an elongated element comprising:
- a bundle of fibers of a predetermined length having a core portion formed from a plurality of straight fibers and a sheath portion wrapped about said core portion and formed from crimped thermoplastic fibers partially adhered to each other; and a sheet of material wrapped around the outer periphery of said bundle of fibers;
- removing said sheet of material and said fibers of said sheath portion at one end of said elongated element while said fibers of said core portion are retained so that one end of said core portion becomes exposed; and
- applying heat and pressure to said thermoplastic fibers over a region adjacent said exposed end portion of said core portion to heat-soften, radially compact, and bond together the thermoplastic fibers in said region about said core fibers.
- 3. A method for producing an applicator according to claim 2, wherein said sheet of material is removed from said region in which said thermoplastic fibers are compacted and bonded together.
- 4. A method for producing rod shaped material for an applicator for makeup use comprising:
- feeding a plurality of straight filaments to a flattened bundle of crimped thermoplastic fibers;
- applying solvent or plasticizer to said bundle of thermoplastic fibers;
- feeding sheet material to said bundle of thermoplastic fibers;
- guiding said straight filaments, said bundle of thermoplastic fibers and said sheet material by means of a guide so that said bundle of crimped thermoplastic fibers enwrap said straight filaments with said straight filaments radially centered and said sheet material wraps in turn around said wrapped bundle of thermoplastic fibers to form a continuous elongated body; and
- cutting said continuous body into predetermined lengths so as to form elongated elements of said predetermined length.
