Fibers are long, thin strands of material that are typically flexible and strong. They can be natural, such as cotton, wool, or silk, or synthetic, such as polyester or nylon. Fibers are used in a variety of applications, including textiles, ropes, and composites. They can be woven or knitted together to create fabrics for clothing, upholstery, and other products. Fibers can also be used in non-textile applications, such as in construction materials or medical devices.

Definition:
Fibers are long, thin, flexible structures found in plant cell walls and the connective tissues of animals.
Plant Fibers:
- Cellulose: The most abundant plant fiber, providing structural support and rigidity to cell walls.
- Hemicellulose: A branched polymer that bonds with cellulose and lignin, contributing to cell wall strength.
- Lignin: A complex polymer that bonds with cellulose and hemicellulose, adding stiffness and durability to cell walls.
- Pectin: A polysaccharide that helps form the middle lamella, the layer that connects adjacent cell walls.
Animal Fibers:
- Collagen: The most abundant protein in the body, forming the main structural component of bones, tendons, and skin.
- Elastin: A flexible protein that provides elasticity to tissues, such as blood vessels and lungs.
- Reticular fibers: Thin, branching collagen fibers that form networks in connective tissues.
Properties:
- Strength: Fibers are extremely strong and resistant to tensile forces.
- Flexibility: Fibers can be bent and twisted without breaking.
- Insolubility: Most fibers are insoluble in water and organic solvents.
- Biodegradability: Plant and animal fibers are biodegradable, meaning they can be broken down by microorganisms.
Functions:
- Structural support: Plant fibers provide strength and rigidity to plant cell walls. Animal fibers form the framework of connective tissues.
- Water retention: Plant fibers hold water within cell walls, providing hydration to plants.
- Wound healing: Collagen fibers play a crucial role in wound healing by forming a scaffold for new tissue growth.
- Tissue elasticity: Elastin fibers allow tissues to expand and recoil, enabling movement and flexibility.
- Thermal insulation: Animal fibers, such as wool, trap air and provide insulation against cold temperatures.
Applications:
- Textiles: Plant and animal fibers are used in the production of clothing, bedding, and other fabrics.
- Paper: Plant fibers are the primary raw material for papermaking.
- Construction: Plant fibers are used in composite materials, such as fiberglass and wood composites.
- Medicine: Collagen and elastin fibers are used in medical implants and tissue engineering applications.
