Classification of fibres
To classify fibers, we can categorize them based on various factors such as their origin, chemical composition, and physical properties. Here are the common classifications of fibers:
1. Natural fibers: These are derived from natural sources such as plants, animals, and minerals. Examples include cotton, wool, silk, jute, hemp, and asbestos.
2. Synthetic fibers: These are man-made fibers created through chemical processes. They are often categorized into two types:
a. Regenerated fibers: These are made by reconstituting natural materials using chemical processes. Examples include rayon, acetate, and bamboo fibers.
b. Polymer fibers: These are produced by synthesizing polymers from petrochemicals. Common examples are polyester, nylon, acrylic, and spandex.
3. Semi-synthetic fibers: These are fibers derived from natural materials but modified through chemical processes. They combine the properties of both natural and synthetic fibers. Examples include modal, lyocell, and viscose.
4. Inorganic fibers: These fibers are produced from inorganic materials such as glass, ceramics, and carbon fibers. They are known for their high strength and heat resistance.
5. Specialty fibers: These fibers possess specific properties to meet unique requirements. Examples include aramid fibers (used in bulletproof vests), conductive fibers (for applications like electronics), and optical fibers (for transmitting light signals).
To determine the classification of a particular fiber, you can refer to its label or conduct tests to gather information about its origin, chemical composition, and physical characteristics.
