The process or processes used in the production of single yarns or of fabrics generated directly from polymer.

  1. Yarn from Staple Fiber : The formation of a yarn by a combination of drawing or draftinh and twisting prepared strands of fibers, such as roving.
  2. Filament Yarn :  In the spinning of manufactured filaments, fiber-forming subtances in the plastic or molten state, or in solution, are forced through the fine orifices in a metallic plate called a spinneret, or jet, at a controlled rate. The solidified filaments are drawn=off by rotating rolls, or godets, and wound onto bobbins or pins. There are several methods of spinning manufactured. Dry, Gel, Wet, Melt, Reaction and Phase Separation Spinning
