Fiber-yielding plants have been critical to man and they rank second just to food plants in their handiness. In antiquated times, plants were of significant assistance in fulfilling man’s necessities in regard to food, apparel, and haven. Albeit different materials like creature skin and stows away were additionally used to meet the requests with respect to apparel, they were very deficient for the reason. 

Further, the requirement for some lighter and cooler substance was distinctly felt. Back then, man likewise required some type of cordage for his catches, bow-strings, nets, and so on, and furthermore for better kinds of coverage for his asylum. Extreme, adaptable strands acquired from stems, leaves, roots, and so forth, of different plants, filled the above needs quite well. With the progression of development, the utilization of plant strands has steadily expanded and their significance today is exceptionally perfect. Albeit a wide range of types of plants, generally, around at least 2,000, are currently known to yield filaments, monetarily significant ones are tiny in number.

In trade, ‘strands’ incorporate basically all little, slim, parts of any substances. There are strands of mineral beginning (asbestos, turned glass, etc) and of creature beginning (fleece and other creature hair, silk, feathers, etc), as well as the more significant plant strands. The filaments might be assembled into two general classifications, to be specific, (I) normal strands, and (ii) engineered or fake strands. The regular strands incorporate filaments got from plants and creatures. Fleece, hairs of a large number of the creatures, and silk are creature filaments. Almost 90% of the world’s creation of filaments is from normal vegetable strands.

The plant filaments are among the most significant of the world’s yields, and an important product in world exchange since they are fundamental for an individual to produce quite a bit of his dress, his cordage, and coarse textures. The plant strands are ordered into their gatherings as per their physical beginning in the plant.

Delicate, Stem, or Bast Fibers

These are sclerenchyma strands related to the phloem, pericycle, or cortex of the stems of plants. They are subsequently somewhat simple to isolate from fundamental woody tissues as a constituent of the ‘bark’ which can be stripped from the stems, They emerge with essential tissues from the apical meristem, or with auxiliary tissues created by the sidelong meristem, the cambium, related with the vascular tissues of the stem. Significant bast strands are flax, jute, hemp, kenaf, ramie, and so forth.

Hard, Leaf, or Structural strands

The hard strands are heaps of little, short lignified cells unsheathing xylem and phloem which happen in the leaves of certain monocotyledons, outstanding models are Agaves, Manila hemp, Sansevieria, Mauritius hemp. 

Seed and Fruit strands

Surface hairs related to the products of the soil of plants are single-celled outgrowths from the testa or from the ovary wall, which safeguard creating seeds. Cotton, which has a place in this gathering, comprises the surface hairs delivered by the testa of the seeds of developed types of the family Gossypium. Kapok, which is the floss, filling the cases of the tree, Ceiba pentandra, comprises single-celled, glistening hairs with a waxy covering, which develop from the ovary wall.  In the coconut, the natural products have sclerenchymatous strands, which are hard because of high lignifications. 

Fiber yields can likewise be grouped in light of their applications and utilization:

  • Material strands: It is the main gathering; the filaments are utilized for the production of textures, mesh, and cordage. The material strands of financial significance are cotton, flax, kenaf, hemp, Roselle hemp, deccan hemp, sun hemp, and so forth.
  • Brush filaments: It is intense and firm strands utilized for the production of brushes and brushes.
  • Unpleasant winding around filaments – level, malleable stringy strands utilized for making straw caps, shoes, bushels, mats, seat seats, and so on. These incorporate hard filaments like Palmyra leaves, Coconut coir, and Agave strands.
  • Filling strands: Filaments utilized in upholstery and for stuffing pads, beddings, pads, and so on. They are likewise utilized as pressing materials. These incorporate Cotton, floss of numerous species ex. Calotropis, Inflorescence of Aerva tomentose, delicate pieces of coir, sun hemp, and so forth.
  • Normal filaments: It boasts extricated from the bark in layers or sheets and utilized alternative for fabric or trim.
  • Paper-making filaments:  Wood strands, and so on, utilized for papermaking.

Fiber crops will be crops that are developed for their strands. They are farming yields utilized for assembling materials, paper, and ropes. Cotton and Jute are two fiber crops.

Conditions expected for the development of cotton

Cotton is a plant that needs a long ice-free period, a ton of intensity, and a lot of daylight. It favors a warm and moist environment. Cotton seeds will have a little germination rate, on the off chance that the dirt temperature is beneath 60°F (15°C). During dynamic development, the ideal air temperature is 70 to 100°F (21-37°C). Temperatures well above 100°F are not alluring. In any case, the typical cotton plant can get by in temperatures up to 110°F (43°C) for brief periods without extraordinary harm, however, this additionally relies upon the moistness levels. To develop cotton plants effectively, we will not have incessant rainfalls during the growing (summer) and during the times of reap (during pre-winter).

  • High temperature north of 27 degrees C during the developing time.
  • Precipitation over 60 cm to 10 cm with tenacious showers.
  • All around depleted soil.
  • Clear, bright, and dry climate during the development of cotton balls.

Conditions expected for the development of Jute

  • Temperature and Humidity: Jute flourishes well in a warm moist environment. Month to month normal temperature to the degree of 26 degrees Celsius is great. The temperature might vary between 24 degrees Celsius and 37 degrees Celsius, the ideal being around 34 degrees Celsius. Normal stickiness of 80% to 90% is important.
  • Precipitation: Jute is a parched plant. Jute requires adequate precipitation very much appropriated over the time of development. The pre-rainstorm fall however low (differing from 25 centimeters to 55 centimeters) is fundamental as it advances the development of the plant until it gets weighty water. Yearly typical precipitation surpassing 150 centimeters is great for Jute cultivation­. Infrequent rainfalls at stretches favor the development of Jute.
  • Soils: Jute plant is called a fruitfulness debilitating plant. Hence, Jute needs new alluvial soils. Without any new alluvial soils, the utilization of substance compost is required. Jute is likewise filled in clayey soils, yet the filaments become tacky. Sandy soils produce coarse fiber.
  • Water bodies: Water for a dousing of plants and is expected to wash the striped fiber.

Frequently Asked Questions

Question 1: Where are fiber crops developed?


Gujarat, Maharashtra, and Andhra Pradesh are significant cotton-creating states. Cotton is the primary fiber crop in India. It gives the basic natural substance (cotton fiber) to the cotton material industry.

Question 2: What is the temperature of fiber crops?


Plants need a high temperature between 25 degrees Celsius to 35 degrees Celsius (roughly). High relative dampness is additionally required. Precipitation: About 170 to 200 cms.

Question 3: What kind of soil and environment is expected for developing jute and cotton?


Stream bowls or alluvial or loamy soils are best for jute development. Cotton is developed between scopes of 37° north and 30° south in mild, subtropical, and tropical districts and on each landmass. Ideal circumstances for the cotton plant are Long vegetation periods (175 to 225 days) without ice.
