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

$X$ 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 $Z$?

  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.

Spandex is used in garments because :

  1. elasticity.

  2. strength.

  3. biodegradable.

  4. Both A and B.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Spandex, Lycra or elastane is a synthetic fiber known for its exceptional elasticity. It is stronger and more durable than natural rubber. Because of its elasticity and strength (stretching up to five times its length), spandex has been incorporated into a wide range of garments, especially in skin-tight garments. A benefit of spandex is its significant strength and elasticity and its ability to return to the original shape after stretching and faster drying than ordinary fabrics.

Weaving is the process of 

  1. Separating seeds from cotton bolls

  2. Spinning of yarn

  3. Arranging two sets of yarn together to make a fabric

  4. Immersing stems of jute plant in water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Cloth is made by crossing two sets of threads over and under each other. The two sets of threads are called warp and weft.

Therefore, the correct answer is option C.

The major defects of rubber belts are

  1. Costly

  2. Slips on wet

  3. Early rubbed

  4. Increased due to heat
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rubber belt slips on wet due to loosing of grip. It also slips because the rubber is a type of material that always remains compressed in nature. Rubber belts are made up of synthetic rubbers or natural rubber.                                     So, the correct option is 'Slips on wet'.

The most common type of belt is made up of

  1. Rubber

  2. Kirmich

  3. Leather

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

Belts made of rubber are most common because rubber is more flexible and is less expensive than leather. Because of its elasticity, toughness and smooth nature, it is mostly used. These are also made of natural and synthetic rubber. So, the correct option is 'Rubber'.

Multiple choice biology waste products reduce, recycle, reuse importance of the conservation of natural resources recycling

Which of the following is non-biodegradable?

  1. Tea leaves

  2. Nylon

  3. Remains of animals

  4. Fleece of sheep
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The correct answer is 'nylon'

Nylon is a synthetic polymer that is known for its resistance to biological degradation and is thus non-biodegradable. Tea leaves remain of animals and fleece of sheep are all natural things on which the enzymes of the microbes can be functional and thus can be degraded by them.

Multiple choice chemistry man made materials plastic and environment pollution due to plastics environmental impact: plastics

To which of the following 4R principle apply most?

  1. Synthetic fibre

  2. Natural fibre

  3. Plastic

  4. Metals
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
4R principle was develped for solid waste management and stands for:
Reduce-the use of non-biodegradable materials,
Reuse-materials again and again,
Recycle-use the materials that can be recycled, and
Recovery-of lacking substances
It is mostly applicable to plastics because they are widely used in day-to-day life and are non-biodegradable possesing threat to the ecology.
Option C is correct.
Multiple choice chemistry man made materials plastic and environment pollution due to plastics environmental impact: plastics

Which of the following material take the longest to degenerate ?

  1. Paper

  2. Cotton cloth

  3. Tin can

  4. Plastic bags
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Plastic bags, because they are complex polymer of long chain hydrocarbons.It is non biodegradable. Plastic bags do not break down naturally. When we dispose them in a garbage pile, the air, moisture, climate, or soil cannot break them down naturally to be dissolved with the surrounding land. However natural waste and products made from nature break down easily when they are disposed as waste.

Multiple choice chemistry states of matter: boiling, evaporation and condensation atmospheric pressure and boiling point evaporation - factors and effects in daily life changes in physical state - boiling, evaporation and condensation

Why do we wear cotton clothes in summer?

  1. cotton absorbs water

  2. it leads to sweating

  3. both a and b.

  4. none of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cotton absorbs water, and thus, causes sweating. Sweat comes out the clothing and in contact with the atmosphere. It evaporates taking up the heat from the surrounding and thus, gives a cooling effect.

Acrylic is used for making carpets and blankets.

  1. True

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

Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of $\sim100,000$, about $1900$ monomer units. Strong and warm, acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn.
option A is correct

  3. In ancient times, stitching was known.

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

In ancient times, stitching was not known. People simply draped the fabrics around different parts of their body.
