Fibers can be categorized into three main types: natural fibers, artificial fibers, and synthetic fibers.
Natural Fibers: These fibers are obtained from natural sources and are not chemically modified. Examples of natural fibers include cotton, wool, silk, jute, hemp, and flax. These fibers are derived from plants, animals, or minerals and have been used by humans for thousands of years.
Artificial Fibers: Also known as semi-synthetic fibers, these fibers are derived from natural materials but undergo chemical processing to create the final fiber. One common example is rayon, which is made from cellulose obtained from wood pulp. Lyocell is another example of an artificial fiber made from wood pulp using an environmentally friendly process.
Synthetic Fibers: These fibers are entirely man-made and are created through chemical processes. Examples of synthetic fibers include polyester, nylon, acrylic, and spandex. These fibers are designed to have specific properties and characteristics for various applications.
So, fibers can be natural (obtained directly from nature), artificial (chemically processed natural materials), or synthetic (entirely man-made).
