Spread or place, the cut edges to make the pattern larger or smaller, as needed. When you spread the sections apart, lay a strip of paper underneath the cut edges. Check the altered pattern measurements to be sure that they are with the measurements, needed then paste, pin or use gummed tape to fasten the pattern pieces in place.

1. Wet Spinning: Examples: Acrylic, Rayon, Spandex. 2. Dry Spinning: Examples: Acetate, Acrylic, Mod-acrylic, spandex, triacetate, vinyon. 3. Melt Spinning: Examples: Nylon, Olefin, Polyester, Saran. After the filaments have been extruded and solidified, they are drawn out between rollers having different speeds. Drawing can also be a separate process. Spinneret size, plus spinning and drawing conditions, determine the final filament diameter. The filaments can be combined into a tow and then chopped into staple fibers. Man-made fibers may be spun into yarns, either alone or as blends with other fibers.
