Natural Fibers – fibers from the nature
All fibers which come from natural sources (animals, plants, etc.) and do not require fiber formation or reformation are classed as natural fibers. The natural fibers are vegetable, animal, or mineral in origin. Some of the natural fibers like vegetable fibers are obtained from the various parts of the plants. They are provided by nature in ready-made form. It includes the protein fibers such as wool and silk, the cellulose fibers such as cotton and linen, and the mineral fiber asbestos.
Textile fibres are normally broken down into two main classes, natural and man-made fibres. All fibres which come from natural sources (animals, plants, etc.) and do not require fibre formation or reformation are classed as natural fibres.
Natural plant and animal fibres have provided the raw materials to meet our fibre needs. No matter which climatic zone humans settled, they were able to utilize the fibres of native species to make products such as clothes, buildings, and cordage. The use of composite materials dates from centuries ago and it all started with natural fibres.
Natural fibres are found in natural surroundings; there are two classifications, which fibres being either animal or plant-based. All natural fibres have to be processed to make them suitable for use as yarns and fabrics.
Natural fibre is any hair like raw material directly obtainable from animals, vegetables or mineral source and convertible into nonwoven fabrics such as felt or after spinning into yarns or woven cloth.
Properties of Natural Fibres
Fibres are all unique, with their own set of characteristics, advantages and disadvantages. These are called properties. Sometimes one fibre is mixed or blended with another to improve its properties.
Vegetable fibres are obtained from the various parts of the plants. These fibres are classified into three categories depending on the part of the plant from which they are extracted. Those three categories are bast or stem fibres (jute, mesta, banana etc.), leaf fibres (sisal, pineapple, screw pine etc.) seed fibres (cotton, coir, old palm etc.).

Many of the plant fibres such as coir, sisal, jute, banana, pineapple, and hemp find applications as a resource for industrial materials. Properties of natural fibres depend mainly on the nature of the plant, locality in which it is grown, the age of the plant, and the extraction method used.
A natural fibre also may be further defined as an agglomeration of cells in which the diameter is negligible in comparison with the length. In some applications, natural fibres are replacing glass fibres in reinforced polymers, where the tensile strength of the fibre is not as important as the specific stiffness. Natural fibre reinforced polymers are generally restricted for use in non-structural products.
In contrast, fibres from natural sources are provided by nature in ready-made form.
Natural fibres include the protein fibres such as wool and silk, the cellulose fibres such as cotton and linen, and the mineral fibre asbestos.
Plant fibres can be further on classified as:
- Fibre occurring on the seed (raw cotton, java cotton)
- Phloem fibre (flax, ramie, hemp, jute)
- Tendon fibre from stem or leaves (Manila hemp, sisal hemp etc)
- Fibre occurring around the trunk (hemp palm)
- The fibre of fruit/ nut shells (coconut fibre – Coir)
Cotton and Linen (made from Flax pant) are the most important among them.

Natural fiber suits everyone and creates no harm to humans and also nature as it is completely degradable and that the good thing about natural fabrics.
