Natural fibers

Definition

Natural fibers are materials derived from plants, animals, or minerals that can be spun into yarn or thread for use in textiles and other applications. These fibers are biodegradable and often have unique properties, making them desirable for various uses including clothing, home textiles, and composite materials. The ability to process and manipulate natural fibers connects them to essential techniques in fiber spinning and their incorporation into fiber-reinforced composites.
