Multiple choice chemistry man made materials environmental impact: plastics plastic plastic plastic waste garbage in, garbage out

Synthetic fibers are obtained from which of the following?

  1. Plants

  2. Sheeps

  3. Chemicals

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

Synthetic fibres are created by extruding fibre forming materials through spinnerets into air and water, forming a thread. These artificially manufactured fibres were made from polymers obtained from petro chemicals. These fibres are called synthetic or artificial fibres. The two most common ones are nylon and polyester. Nylon is made from two chemicals, adipic acid (AA) and hexamethylene diamine (HMD).

Therefore, the correct answer is option C.

Fibre obtained by chemical treatment of wood pulp is called:

  1. natural Silk

  2. rayon

  3. nylon

  4. polyster
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Natural Silk: The protein fibre of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons.
Rayon: Rayon is a manufactured regenerated cellulose fibre. It is made from purified cellulose, primarily from wood pulp, which is chemically converted into a soluble compound.
Nylon: Nylon is a strong, light synthetic fibre. Nylon thread is made from the polymerization of an amine and an acid chloride. 
Polyester: Polyester is a synthetic polymer made of purified terephthalic acid or its dimethyl ester dimethyl terephthalate and mono ethylene glycol. 

Hence, the correct option is $B$

  1. Flax

  2. Coir

  3. Cotton

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

Cotton fibres (Gossypium) are the outgrowth of the epidermis. These are the epidermal cells and they become elongated.

So the correct option is C.

Which of the following is grown as most important source of textile fibres in Bengal

  1. Crotolaria

  2. Gossypium

  3. Corchorus

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

(c) Corchorus is mainly grown in Bengal because of the climatic and soil conditions of this region. These conditions are favourable to this crop and abundant water of Hugli river is available for the rotting of fibres.

So the correct option is C.

Jute fibre deteriorates quickly due to presence of

  1. High cellulose

  2. Low cellulose

  3. High lignin

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

Jute fiber is a lignocellulosic fiber. High lignin content makes the fiber more resistant to degradation, but in the context of commercial processing and quality, high lignin content is often associated with lower flexibility and faster deterioration under certain environmental conditions compared to pure cellulose fibers.

Which one of the following is known as the golden fibre?

  1. Cotton

  2. Jute

  3. Hemp

  4. Silk
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Jute
Jute is extracted from the bark of the white jute plant (Corchorus capsularis) and to a lesser extent from tossa jute (C. olitorius). It is a natural fibre with golden and silky shine and hence called the Golden Fibre. Jute is an annual crop taking about 120 days (April/May-July/August) to grow. Also, since jute is a cash crop, its cultivation can bring in lot of money.
