Classification of fibres
Fibres can be classified into various categories based on different parameters. Here are some common classifications of fibres:
1. Natural fibers vs. Synthetic fibers: Fibres can be either natural or synthetic. Natural fibres are obtained from natural sources, such as plants (cotton, jute), animals (wool, silk), or minerals (asbestos). Synthetic fibres, on the other hand, are man-made and are derived from chemicals (polyester, nylon).
2. Plant fibers vs. Animal fibers: Natural fibers can be further classified as plant fibers or animal fibers. Plant fibers include cotton, jute, hemp, flax, and bamboo, while animal fibers comprise wool, silk, and hair from other animals like cashmere and angora.
3. Regenerated fibers: These fibers are made by converting natural materials into fibres. Rayon, modal, and lyocell are examples of regenerated fibers that are derived from cellulose or wood pulp.
4. Mineral fibers: These fibers are made from minerals and are primarily used in insulation and fireproofing. Examples of mineral fibers include asbestos and fiberglass.
5. Synthetic fibers: Synthetic fibers are man-made and are created through various chemical processes. Common synthetic fibers include polyester, nylon, acrylic, and spandex.
6. Microfibers vs. Macrofibers: Fibres can also be classified based on their diameter. Microfibers have a diameter less than 10 micrometers and are used for applications such as fabrics, filters, and medical applications. Macrofibers have a larger diameter and are used for structural reinforcements in composites.
It's important to note that this is not an exhaustive list, and there may be other ways to classify fibers based on specific characteristics or applications.
