What to Focus On

  • Yarn is a continuous strand of fibers twisted together.
  • Spinning is the process of making yarn from fibers.
  • Natural fibers are spun mechanically; synthetic fibers are spun chemically using a spinneret.
  • Fineness refers to the thickness of the yarn – finer yarns are smoother and stronger.
  • Twist holds fibers together and affects fabric texture and strength.
  • High twist creates crinkled fabrics like georgette.
  • Staple yarns are made from short fibers and are fuzzy, warm, and absorbent.
  • Filament yarns are made from long, continuous fibers and are smooth and lustrous.
  • Textured yarns are modified filament yarns with crimps or loops to add bulk and comfort.

Common Mistakes to Avoid

All yarns are made by twisting fibers together, so filament yarns must also be twisted like cotton yarns.

More twist in a yarn always makes it stronger, so highly twisted yarns are best for all fabrics.

Thread and yarn are the same thing; the terms can be used interchangeably.

Memory Tips
