Description
A class of fibers that includes all non-synthetic fibers. Natural fibers are generally separated into three groups based on origin (with some examples):
1) plant fiber: Cotton, Linen, Jute, Abaca.
2) animal fiber: Wool, Silk, Fur.
3) Mineral fiber: Asbestos, graphite, quartz.
Wool and dyed flax, have been found in prehistoric caves indicating their early usage. And many natural fibers are still in wide use because they have many advantages over Synthetic fibers, such as lower density, better thermal insulation, and reduced skin irritation. Natural fibers are good water absorbents and can be found in various textures. Cotton fibers made from the cotton plant, for example, produce fabrics that are light in weight, soft in texture, and which can be made in various sizes and colors.
