Fibers
- Fiber is a long, thin substance, significantly longer than wide.
- Often used in materials like those containing carbon fibers and high-molecular-weight polyethylene
- Natural fibers are made from plants or animals, sometimes for composite materials or sheets like paper/felt
- Earliest examples of fiber use include wool and flax, dated back to 36,000 years ago
- Natural fibers are better for comfort and are better at absorbing sweat while being more degradable.
Natural Fibers
-
Vegetable Fibers
-
Leaf Fibers (e.g., cordage): Tough, rigid fibers used for rope, typically high in lignin content. Examples:
- Abaca (Manila Hemp) – source of lustrous fibers, often a material for textiles.
- Piña – plant fiber from pineapple leaves (lace-like textiles)
- Sisal – another important leaf fiber used for rope/matting, harvested from plants.
-
Seed Fibers (e.g., cotton): Examples of softer, lightweight, comfortable fibers
- Cotton: Most important textile fiber crop globally.
-
Leaf Fibers (e.g., cordage): Tough, rigid fibers used for rope, typically high in lignin content. Examples:
- Animal Fibers (e.g., wool): Made from animals like sheep.
- Mineral Fibers (e.g. Asbestos): Naturally occurring fibrous minerals, resistant to heat and corrosion
Fiber Extraction
- Methods vary depending on the type of fiber
- Process of decortication (for leaf fibers) involves scraping or removing non-fibrous plant parts.
- Plants sometimes are manually handpicked.
- Additional processes may involve combing/sorting.
Additional Details
- Clothing made of natural fibers is often preferred in hot, humid climates.
- Fibers are sometimes extracted prior to fabric production.
