Method and apparatus for high denier hollow spiral fiber |
摘要 |
An apparatus and method for producing self-texturing hollow fiber that exhibits a desirable tendency to coil rather than to bend sharply or zig-zag. In one embodiment the invention is a spinneret for the production of hollow filament having first and second curved slots where each slot is defined by a first end having a first width and a second end having a second width and where the first and second ends are separated by an intermediate portion possessing a non-uniform width. In another embodiment the invention is a method for of producing generally cylindrical hollow filaments comprising extruding a polymer melt through a spinneret having first and second curved slots where each slot has a first end having a first width and a second end having a second width and where the first and second ends are separated by a intermediate portion possessing a non-uniform width along the continuum defined by the distance between the first end and the second end.
