  2. cotton ball

  3. cocoon

  4. shiny jute stalk
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

$C$

Cocoon is a protective case of silk or similar fibrous material spun by the larvae of moths and certain other insects as a cover for the pupa. The cocoon is made of a thread of raw silk from $300$ to about $900 m (1,000 to 3,000 ft)$ long. The fibres are very fine and lustrous, about $10 μm (0.0004 in)$ in diameter.

Multiple choice chemistry fibre to fabric: plant fibre yarn to fabric from fibre to fabric processing of fibres

State whether true or false :

Retting is needed to separate cotton fibres from the stem of the plant.

  1. True

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

Retting is a method which is used on plants to rot away the cellular tissues and gummy substances surrounding the fibre bundles. 


This helps in easy separation of the fibre from the stem. 

This is done by the action of bacteria and moisture on plants. Hence, retting is needed to separate cotton fibres from the stem of the plant.

Thus, the correct answer is 'True.
