Definitions

  • Small diameter fibers are commonly made with the "islands in the sea” design. This is where many small fibers made up of one material are extruded within another sacrificial material, so that once the outer sacrificial material is washed away, what remains are many small individual diameter fibers. This allows the encapsulated plurality of fibers to be stretched when cooled while still maintaining their inner shape, but allowing for smaller diameter, individual fibers to be made.
  • each leg has opposite first sides, wherein each of the opposite first sides having a plurality of the protrusions extending laterally outwardly therefrom.
  • the method further includes extruding protrusions simultaneously with the legs, with the protrusions extending laterally outwardly from at least some of the legs and extending lengthwise in generally parallel relation with one another and with the central axis to form second channels between adjacent protrusions.
  • the method further includes co- extruding an outer sheath about the inner fiber from a second material that is different from the first material, such that the outer sheath at least partially fills the first and second channels.
  • the method former includes extruding each leg having opposite first sides, and extruding a plurality of the protrusions extending outwardly from each of the opposite first sides.
  • the method further includes extruding each protrusion extending to a second peak, and extruding each of the protrusions having opposite second sides converging toward the second peak.
  • the method can further include providing the second material as being dissolvable in water.
  • the fiber 10 includes a continuous inner fiber 11 that extends lengthwise along a longitudinal central axis 12.
  • the inner fiber 11 has a plurality of legs 14 extending lengthwise in generally parallel relation with one another and with the central axis 12.
  • Each of die legs 14 extend radially outwardly in branched fashion away from a central body 16 of the inner fiber
  • each of the channels 20 extend in generally parallel relation with one another and also with the central axis 12.
  • At least some of the legs 14, and shown here as each of the legs 14, have elongate ridges and also referred to as lobes, ridges, fingers, protrusions or arms 22, extending laterally outwardly therefrom.
  • Each of the arms 22 extends radially outwardly to a second peak 24.
  • the fiber 10 is initially formed as a bi-component co-extrusion, with the inner fiber 11 being extruded from a first material having the geometric features described above extruded coincident with the central axis 12, and with an outer sheath 28 being simultaneously extruded, referred hereafter as coextruded, from a second material about the first material.
  • the outer sheath 28 can fully encapsulate or partially encapsulate the inner fiber 11 to either completely fill or at least partially fill the first and second channels 20, 26, wherein the first and second materials are different types of material.
  • the fiber 10 can first be processed as a generally standard monofilament having a generally circular cross-section, or otherwise, including a generally oval or flatted cross- section, and then after forming the end product, the outer sheath 28 can be dissolved to exposed the encapsulated inner fiber 11.
  • processing the inner fiber 11 into the textile fabric can be made easy, as with a standard monofilament, and thereafter, the more complex shape of the inner fiber 11 can be exposed by dissolving the outer sheath 28 away from the inner fiber 11.
  • any suitable solvent can be used, depending on the material content of the second material, such as NaOH, acids, or in the case of a water-soluble polymer such as Exceval, water can be used to dissolve the outer sheath 28.
