Study Notes
Fiber Cohesion and Unevenness
- Cohesion is less important for staple fibers than for filament fibers due to unevenness.
- Unevenness refers to the variation in the surface characteristics of fibers.
- Filament fibers have a more consistent surface, leading to stronger cohesion compared to staple fibers with their irregular surfaces.
- Various fiber types exhibit different surface characteristics:
- Acrylic, spandex: Dog-bone shape
- Modified nylon or polyester: Square with voids
- Silk: Triangular, rounded edges
- Wool: Oval with overlapping scales
- Cotton: Flat, oval lumen, convolutions
- Rayon: Lobular, lengthwise striations
- Nylon, polyester: Circular, uniform in diameter
- Flax: Polygonal lumen
- Acetate: Trilobal
