Abstract
This invention relates to methods for manufacturing super-micro fibers to produce fibers having dimensions of between 0.003-0.0003 denier per filament. The manufacturing methods include the following steps: blending polyamide-polyester mixtures; passing said polyamide-polyester mixtures through single-path and twin-screw extrusion processes; spinning said polyamide-polyester mixtures; melting and dissolving said polyamide-polyester mixtures; and separating polyester compounds from said polyester-polyamide mixtures to form polyamide compound or super-micro fibers.
