  1. True

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

Spun yarns are long continuous length of interlocked fibers, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, and rope making. 


Thread is a type of spun yarn intended for sewing by hand or machine. 

Spun yarns can be made from a number of natural or synthetic fibers.

Therefore, option A is correct.

Multiple choice chemistry substances in daily use polyester and acrylic rayon and nylon synthetic fibres

Which of the following do not contain polyester fabric?

  1. Terrywool

  2. Terrycot

  3. Terylene

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

Terrywool, Terrycot and Terylene all contain polyester.


Orlon is a polymer of vinyl cyanide. It is made by the addition of acrylonitrile molecules. It is a brand of the synthetic, acrylic textile fibre of the lightweight and wrinkle-resistant fabric.

Option D is correct.

Multiple choice chemistry substances in daily use polyester and acrylic rayon and nylon synthetic fibres

Arrange the following fibers in the order of increasing strength:

Nylon, Cotton, Wool, Polyester, Silk

  1. Silk, Wool, Cotton, Nylon, Polyester

  2. Wool, Silk, Cotton, Nylon, Polyester

  3. Cotton, Silk, Wool, Nylon, Polyester

  4. Nylon, Cotton, Silk, Wool, Polyester
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tensile strength of polymer increases with increase in chain length and cross-linking of polymer chains. According to this, the tensile strength of wool < silk < cotton < nylon < polyester. Artificial fibers like nylon and polyester are designed specially to have more tensile strength.

Multiple choice aluminium patterns and properties of metals chemistry

Which of the following materials can make cloth fire-proof?

  1. Copper oxide

  2. Aluminium sulphate

  3. Nickel chloride

  4. Magnesium sulphate
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Aluminium sulphate is used in producing fire proof textiles.

Multiple choice evs roots and leaves plant adaptation and modification leaves root, stem, and leaves

Which of the following varieties of cotton do not attract bollworm?

  1. Hairy leaves

  2. Solid stem

  3. Smooth leaved and nector less
  4. High aspartic acid and low $N _2$ content
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cotton varieties with hairy leaves are known to be resistant to bollworm attacks because the hairs interfere with the insect's ability to lay eggs or feed.

Multiple choice chemistry substances in daily use polyester and acrylic rayon and nylon synthetic fibres

Ropes made of _______ are used in cranes and lifts.

  1. rayon

  2. nylon

  3. acrylic

  4. spandex
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Nylon ropes are used in cranes and lifts because of high tensile strength and elasticity of nylon.


Nylon is the strongest of all ropes in common use. It is used for absorbing shock loads, such as when lifting or towing because it has the ability to return to it's original length after being stretched. 

It also has good abrasion resistance and can last several times longer than natural fibres.

Therefore, option B is correct.

Multiple choice classification of polymers introduction to polymers and its classification polymer polymers chemistry

Rayon is chemically known as:

  1. cellulose nitrate

  2. cellulose

  3. cellulose acetate

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

Rayon is chemically known as cellulose acetate, which is a semi-synthetic kind of polymer.

It is considered as semi-synthetic because it has natural component cellulose which combined with acetate gives cellulose acetate (rayon)

Option C is correct.
