Natural materials are by definition biodegradable. That means that cotton, wool, linen and silk fulfill this criterion. Cotton and linen are cellulose based (a polysaccharide) while wool and silk are made of protein types )wool is made of keratin as is human hair). Of the others only certain types of polyesters are biodegradable such as for example polylactic acid. What is commonly labeled as polyester in garments is not biodegradable.
Just a guess but the fibers in clothing. ( cotton fibers, polyester fibers, etc)
The fibers which are made by man are the synthetic fibers.
Norepinephrine-releasing fibers are called noradrenergic fibers. These fibers are part of the sympathetic nervous system and release norepinephrine as a neurotransmitter.

Collagenous fibers, Elastic fibers, and Reticular fibers
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.

Collagen fibers, elastic fibers, and reticular fibers are the three main types of fibers found in connective tissue. Collagen fibers provide strength and support, elastic fibers offer flexibility, and reticular fibers form a network-like structure to support various tissues and organs.
Elastic Fibers
It is important to know how natural fibers are classified. Natural fibers are fibers from plant, animal and minerals. They are classified according to their origin.
