Definition of Fibres
Long strands of molecules interwoven to form a linear, string-like structure are known as ‘Fibres’. Fibers are natural or man-made such as cotton, silk, jute, etc.
Fibres
Fibers were discovered when early people realized the need to cover and protect their own hair and skin from the weather. Since early people would live in cold climate they hunted animals with skins (fur and food) that kept them warm. When used continuously this skin becomes harder and made it hard for the early men to hunt and hence later they started to treat this skin to maintain its softness. In a much later time, they started using the bones of animals as needle and nerves as the thread to stitch. And now decades later we finally know how to grow our own fibres and make clothes or fabrics out of them.
Characteristics of Fibers
Fibers used in clothing are used to cover the body, to protect our body, etc. Everyone wears clothes for different reasons. Some of the other characteristics of fibres are:
Fibers can be repeatedly stretched more than 500% of its original size and can also recover back; immediately to its original size and shape once the tension is relaxed.
In comparison to rubber, it is stronger and more durable.
It is lightweight.
Natural Fibres
Fibres obtained from plants and animals that can be spun into filament, thread or rope are termed as ‘Natural fibres’. They may be woven, knitted, matted or bonded.
Decades later even though the methods used to make fabrics from fibres may have changed greatly, their functions remain the same:
Most natural fibres are still used to make clothing and containers.
To insulate, soften and decorate our spaces.
Cotton
The journey of a cotton plant starts on a farm where a dry breeze blows across the endless stretch of fields as the woolly cotton seeds are planted in neat rows. When the crops are ready to harvest, the plants are first intensely watered up to 200 days. Cotton is almost pure cellulose. The length of cotton varies from 10 to 65 mm, and the diameter from 11 to 22 microns. Since cotton absorbs moisture easily, it is the most obvious choice as a fabric for clothes.
Wool
Wool is made from shearing a sheep, after which its quality is checked and is later prepared for spinning. This wool is spun into long strands. The strands are then woven into a fabric. Since wool holds moisture without feeling
wet it is a great thermal insulator. The diameter of a wool ranges from 16 microns to more than 40 microns.
jute
silk
there are only 4 naural fibre
hope it helps

Abaca: It's a leaf fibre, composed of long slim cells that form part of the leaf's supporting structure. Lignin content is a high 15%. Abaca is prized for its great mechanical strength, buoyancy, resistance to saltwater damage, and long fibre length – up to 3 m. The best grades of abaca are fine, lustrous, light beige in colour and very strong. Once a favoured source of rope for ship's rigging, abaca shows promise as an energy-saving replacement for glass fibres in automobiles.
Coir: Among vegetable fibres, coir has one of the highest concentrations of lignin, making it stronger but less flexible than cotton and unsuitable for dyeing. The tensile strength of coir is low compared to abaca, but it has good resistance to microbial action and salt water damage. A coarse, short fibre extracted from the outer shell of coconuts, coir is found in ropes, mattresses, brushes, geotextiles and automobile seats.
Cotton: It's almost pure cellulose, with softness and breathability that have made it the world's most popular natural fibre. Fibre length varies from 10 to 65 mm, and diameter from 11 to 22 microns. It absorbs moisture readily, which makes cotton clothes comfortable in hot weather, while high tensile strength in soap solutions means they are easy to wash. Cotton is the world's most widely used natural fibre and still the undisputed "king" of the global textiles industry.
Flax: Like cotton, flax fibre is a cellulose polymer, but its structure is more crystalline, making it stronger, crisper and stiffer to handle, and more easily wrinkled. Flax fibres range in length up to 90 cm, and average 12 to 16 microns in diameter. They absorb and release water quickly, making linen comfortable to wear in hot weather. One of nature's strongest vegetable fibres, flax was also one of the first to be extracted, spun and woven into textiles.
Hemp: Long, strong and durable, hemp fibres are about 70% cellulose and contain low levels of lignin (around 8-10%). The fibre diameter ranges from 16 to 50 microns. Hemp fibre conducts heat, dyes well, resists mildew, blocks ultraviolet light and has natural anti-bacterial properties. Shorter, woody core fibres ("tow") contain higher levels of lignin. Easy to grow without agrochemicals, hemp is used increasingly in agrotextiles, car panels and fibreboard, and "cottonized" for clothing.
Jute: Dubbed the "golden fibre", jute is long, soft and shiny, with a length of 1 to 4 m and a diameter of from 17 to 20 microns. It is one of nature's strongest vegetable fibres and ranks second only to cotton in terms of production quantity. Jute has high insulating and anti-static properties, moderate moisture regain and low thermal conductivity. The strong threads made from jute fibre are used worldwide in sackcloth - and help sustain the livelihoods of millions of small farmers.
Ramie: It's is white with a silky lustre, similar to flax in absorbency and density but coarser (25-30 microns). One of the strongest natural fibres, it has low elasticity and dyes easily. Strands of ramie range up to 190 cm in length, with individual cells as long as 40 cm. Trans-fibre fissures make ramie brittle but favour ventilation. Not widely known outside the East Asian countries that produce it, ramie is lightweight, silky and made for summer.
