Definitions
- the fibers of the present invention are made by combining about 99.9 to about 98.5 weight percent of at least one polyester and about 0.1 to about 1.5 weight percent additive to form a melt extrusion composition.
- the melt extrusion composition is extruded through a non—circular cross—sectional shaped spinneret hole to form a fiber.
- the fiber is quenched, and then taken up.
- the fiber when compared to a second fiber made the same way except that the melt extrusion composition does not contain the additive, has improved shape retention of at least four percent, preferably forty percent.
- the shape factor of the individual as-spun filaments was measured with a computer based image analysis technic.
- the image analysis system consisted of a microscope, a video camera, a personal computer based image processing workstation, a video monitor and a video printer.
- the effect of the amount of additive on the shape factor is shown for Examples 1—8 in Figure 2.
- a comparison is made of a control with no additive to the Examples having varying amounts of PDMS fluids.
- Significant improvement in the shape factor was seen with all Examples.
- a 40 percent improvement in shape factor was observed with the addition of PDMS fluids in these Examples.
