Multiple choice botany fibre to fabric: plant fibre classification of fibres fibres history of fabric

 Fibres can be classified as natural fibres and synthetic fibres.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fibres can be classified as natural fibres and synthetic fibres.
Natural fibres are obtained from plants and animals. The examples of such fibres include cotton, jute, silk and wool.
Synthetic fibres are made from chemical substances, which are not obtained from plant or animal sources. Examples include polyester, nylon and acrylic.

Dispersed dye was originally developed for the dyeing of cellulose acetate,
and are water-insoluble this dye is mainly used to dye:

  1. nylon

  2. polyster

  3. both A and B

  4. wool
Reveal answer Fill a bubble to check yourself
B,C Correct answer
Explanation

Dispersed dyes were originally developed for the dyeing of cellulose acetate and are water-insoluble. The dyes are finely ground in the presence of a
dispersing agent and sold as a paste, or spray-dried and sold as a
powder. Their main use is to dye polyester but they can also be used to dye nylon.
Hence option C is correct.

Which of the following fibre is recyclable?

  1. Hemp

  2. Flax

  3. Sisal

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A, B and C are natural fibres. 


All natural fibres are easily recyclable. It is a renewable resource, the production requires little energy, $CO _2$ is used while oxygen is given back to the environment. 

They are also carbon neutral. They absorb the same amount of carbon dioxide they produce. 

During processing, they generate mainly organic wastes and leave residues that can be used to generate electricity or make ecological housing material. And, at the end of their life cycle, they are 100% biodegradable.

Hence the correct option is D.

$X$ is a thread of filament from which $Y$ is made. If prepared from plants and animals, it is known as $Z$ fibres whereas by humans it is known as $W$ fibres. Synthetic fibres are nylon, rayon, polyester, acrylic etc.
What is $Y$?

  1. Cloth

  2. Paper

  3. Pen

  4. Book
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fibre is the basic unit of raw material having suitable length, pliability, and strength for conversion into yarns and fabrics/material/cloth. 

A fibre of extreme length is a filament. Fibres can occur naturally or can be produced artificially. 

Here, X is a fibre, Y is the cloth/fabric/material. Z is the natural fibre and W is the artificial or human-made fibre.

paper/book is an example of products of natural polymer (cellulose), pen is an example of industrial product of synthetic polymer.

Therefore, option A is correct.

Linen fibre is obtained from __________.

  1. chia seeds

  2. cotton seeds

  3. flax plants

  4. cotton flowers
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Linen yarn is spun from the long fibers found just behind the bark in the multi-layer stem of the flax plant. In order to retrieve the fibers from the plant, the woody stem and the inner pith, which holds the fibers together in a clump, must be rotted away. 

The cellulose fiber from the stem is spinnable and is used in the production of linen thread, cordage, and twine.

So, option C is correct.

To which of the following does the 4R principle apply the most?

  1. Synthetic fibre

  2. Natural fibre

  3. Metals

  4. Plastic
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Plastic is a man-made substance that cannot be broken down by natural microbial action. Hence, the 4R principle is applied to it. 

The 4 R principle is- ${\text{Refuse, Reduce, Reuse and Recycle}}$. This helps in reducing the harmful effect of plastic in the environment. 

Thus the correct answer is option A.

Bed sheets, curtain, tents, parachutes can be made from :

  1. Natural fibre

  2. Synthetic fibre

  3. Yarn

  4. Plastics
Reveal answer Fill a bubble to check yourself
A,B,C Correct answer
Explanation
Bed sheets, curtain, tents, parachutes are made from fabric like cotton, silk, nylon, rayon etc. and the fabric is a cloth produced by weaving or knitting textile fibers. 

These fibers can be obtained naturally from plant or animal sources like cotton seeds and silk, wool or can be synthesized like nylon or rayon.

Therefore, natural and synthetic fibers are used to make fabric.

Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking. Thread is a type of yarn intended for sewing by hand or machine.

Plastics are synthetic polymers and not used in fabric production.

Hence, option A, B and C are correct.

What is $Z$?

  1. Plant fibre

  2. Animal fibre

  3. Natural fibre

  4. Artificial fibre
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Fibre is the basic unit of raw material having a suitable length, pliability, and strength for conversion into yarns and fabrics/cloth/material. 

A fibre of extreme length is a filament. Fibres can occur naturally or can be produced artificially. 

Here, X is a fibre, Y is the cloth/fabric. Z is the natural fibre and W is the artificial or human-made fibre.

Plant and animal fibre are natural fibres, and artificial fibre are man-made fibres such as rayon.

Therefore, option C is correct.
