Protein fibers are essentially the hairs that grow on animals. 
The examples are:
These are just a few examples of protein-based yarn fibers. Other types include mohair, silk, camel, and llama, among others.
Synthetic fibers are man-made fibers that are produced from petrochemicals, coal, or other materials. These fibers are created through a process called polymerization, in which small molecules called monomers are chemically bonded together to form long chains of polymers.
Synthetic fibers have become increasingly popular in recent years due to their affordability, durability, and versatility. Some common types of synthetic fibers include polyester, nylon, acrylic, rayon, spandex.
While synthetic fibers have many benefits, they also have some drawbacks. For example, they are not as breathable as natural fibers, and they can release microplastics into the environment when they are washed. However, advancements in technology have led to the development of more sustainable synthetic fibers, such as recycled polyester and biodegradable plastics
Cellulose fibers are a type of natural fiber that are derived from plant sources. These fibers are made from cellulose, which is the main component of plant cell walls. Cellulose fibers are known for their softness, breathability, and ability to absorb moisture.
Some common types of cellulose fibers include:
The examples are:
Cellulosic fibers are also made from cellulose of plant material (mostly often cotton and
trees) that has 
been chemically processed down to a base liquid form before being extruded and regenerated into a spinnable fiber form.
The most common cellulosic fibers are rayon and Tencel. Probably you also heard about lyocell, modell and acetate.
I am a passionate knitter who wants to share my love for this wonderful craft with the world. I believe that knitting is more than just a hobby – it’s a way to express your creativity, connect with others, and even promote mindfulness and relaxation.
