Which of the following characteristics distinguishes filament yarns from staple yarns?
Which of the following characteristics distinguishes filament yarns from staple yarns?
- Staple yarns are made from short fibers twisted together, while filament yarns are made from long, continuous fibers. (correct)
- Filament yarns are typically composed of natural fibers like cotton and wool, whereas staple yarns are synthetic.
- Filament yarns are smoother and less prone to pilling compared to staple yarns.
- Staple yarns are made from long, continuous fibers, while filament yarns are made from short fibers.

What alteration is primarily responsible for transforming a flat filament yarn into a textured filament yarn?
What alteration is primarily responsible for transforming a flat filament yarn into a textured filament yarn?
- Chemically treating the fibers to increase their tensile strength.
- Coating the yarn with a polymer to enhance its smoothness.
- Altering the yarn to provide bulk, stretch, or a more natural appearance. (correct)
- Twisting multiple single yarns together to increase thickness.

Study Notes
Staple vs. Filament Yarns
- Staple yarns consist of short fibers twisted together (e.g., cotton, wool).
- Filament yarns consist of long, continuous fibers (e.g., silk, synthetic fibers like polyester).
Flat Filament vs. Textured Filament Yarns
- Flat filament is smooth, compact, and has no added texture, it is often used in shiny, silky fabrics.
- Textured filament is altered to provide bulk, stretch, or a more natural fiber-like appearance (e.g., crimped polyester).
"Ply" Definition
- "Ply" refers to the number of single yarns twisted together to create a thicker, stronger yarn.
- More plies result in increased strength, durability, and reduced pilling.
- Higher ply yarns are often used in stronger, more structured fabrics.
