Firstly we will discuss “What is plant fibre?”
So here we will discuss plant fibres. The plants which have fibres in them are called plant fibres and crops which are sown to get the required fibre such crops are called fibre crops or in case of trees fibres are obtained and their production are called fibre trees. Once they are cultivated then proper climatic conditions are provided to them in order to make them strong enough and then at the right time they are harvested and further processed in the factories in order to extract the required fibres. There is a substance called cellulose present in the plant which gives strength to the fibre. Plant fibres are obtained from cotton and jute.

Here a thing which comes to one’s mind is which substance gives strength to the fibre.

There are mainly two types of fibres which we get from plants namely jute and cotton. These two fibres require different types of climatic conditions to grow. Also as these are obtained naturally therefore they are called natural fibres. These natural fibres are then further processed with chemicals in the industry in order to produce other modified fibres or a variety of fibres.

As these two fibres are obtained from nature therefore, it requires a lot of hardwork and patience and therefore they are quite expensive but the fibres which are manufactured in the industry are cheaper than these but they may cause some other reactions to the skin whereas the natural fibres are mostly safe. Not only for wearing purposes but the fibres play an important role in human life.

Now as it is known that the natural fibres are also of two types which are the fibres which are obtained from plants are called plant fibres and the fibres which are obtained from animals are called animal fibres. It’s the time to discuss the difference between plant and animal fibres.

As we have already discussed, plant fibres get strength from the cellulose present in them in the same animal fibre also need a strength and they get a strength from the protein so we can say that animal fibres contain proteins.
One of the important differences between plant fibre and animal fibre is that plant fibre is obtained from the different parts of the plants like, stem, seeds, and leaves. On the other hand the animal fibres are extracted from the skin of the animals therefore they are bulkier than the plant fibres.
Plant fibres examples are: cotton, jute, flax etc. on the other hand examples of animal fibres are: silk, wool etc.
Jute fibres are obtained from jute plants.

We will be discussing the two most important plant fibres namely cotton and jute. Firstly we will talk about the cotton plant:

Cotton plants come under the category of the shrub.
It is the fibre crop containing the higher percentage of cellulose.
When the ball of cotton gets burst it leads to the dispersal of seeds.
India has quite a good production of cotton constituting a good percentage than the other countries of the world.

Biology of a cotton plant

Here we will discuss the biology of the cotton flower and the other conditions required for the growth of the cotton plant.

Here we will talk about the environmental conditions required for the growth of a cotton plant. So the growth of a cotton plant requires moderate rainfall, frost free time during the growth, and soil with a good holding capacity like black soil. Cotton is best grown in the black soil. This black soil has a good water holding capacity and allows cotton to grow.

Now we will be discussing about another natural fibre i.e jute.

Jute is also a fibre plant which ranges from 3m to 10m.
Jute fibres are obtained from jute plants.
This plant fibre is a little rough in nature but of great variety of uses.
It comprises the cellulose which is the base material for all plant fibres but in addition to that it contains lignin.
It is one of the cheapest natural fibres known.

It is interesting to discuss here how jute fibre is obtained from the jute plant.

Jute plant requires standing water to grow and therefore grows well in the alluvial soil. The process of jute cultivation is as follows:

Firstly the seeds are sown and then the jute is allowed to cultivate in standing water with a good amount of heat required then when the jute gets grown up then the stem of the plant is used to extract jute from it. Then several stems of this jute plant are collected and then dipped or more precisely we can say that it is washed in the slow flowing water then the workforce of the farmers separate the fibres from the unwanted material present. Further it is processed into yarns and then into fibres.

Plant fibers are increasingly used in the automotive industry to create lightweight, eco-friendly components. They can be used in interior panels, seat cushions, and even as reinforcement in composite materials for body parts. This helps reduce vehicle weight, improving fuel efficiency and reducing environmental impact.

43. What is the difference between natural and regenerated cellulose fibers?

Natural cellulose fibers, like cotton or linen, are directly extracted from plants. Regenerated cellulose fibers, such as rayon or lyocell, are made by dissolving natural cellulose (often from wood pulp) and then extruding it into new fibers. While both are based on plant cellulose, regenerated fibers undergo more processing and can have different properties.

44. How do plant fibers contribute to soil remediation efforts?

Some plants used for fiber production, like hemp or flax, can be effective in phytoremediation - the process of using plants to remove contaminants from soil. These plants can absorb heavy metals or other pollutants from contaminated soil. After harvesting, the fibers can still be used for industrial purposes, while the contaminated plant parts are properly disposed of.

47. What is the difference between plant fibers and plant-based synthetic fibers?

Plant fibers are natural fibers directly extracted from plants, retaining their original structure. Plant-based synthetic fibers, like PLA (polylactic acid), are artificially created polymers derived from plant sources. While both originate from plants, synthetic fibers undergo more extensive chemical processing and can have very different properties from natural plant fibers.

48. How do plant fibers contribute to the development of sustainable cosmetics?

Plant fibers are used in various ways in sustainable cosmetics. They can serve as natural exfoliants, replacing microplastics. Nanocellulose from plant fibers can be used as a thickener or stabilizer in cosmetic formulations.
