Test: Fibre to Fabric - Class 6 MCQ

 Figures X and Y represent takli and charkha respectively. Both takli and charkha are used for spinning i.e., process of twisting fibres to make yam.

In the given flow chart, P could be animal fibre like wool or silk. Q could be jute, flax or hemp. R could be sisal and S could be cotton. Wool is used in winter clothing while cotton is used for summer clothing. Plant stem fibres like jute, flax, hemp are generally used for making bags, ropes, carpets, etc. Sisal which is a leaf fibre is also used for almost same Dumoses.

• Ginning (iii): This is the process of separating cotton fibers from the seeds. It involves the use of a machine called a cotton gin.



• Spinning (i): In this step, the separated cotton fibers are spun into yarn or thread using spinning machines.



• Weaving (ii): The spun yarn is then woven into fabric using weaving machines, creating the final cotton cloth.

Therefore, the correct steps involved in processing of cotton are (i), (ii) and (iii) only, which corresponds to option C.

According to the given dichotomous key, P is a synthetic fibre like polyester, Q could be jute, flax, etc. R is cotton, S is silk and T is wool.

• Natural breathable fabric: Cotton is a natural breathable fabric, allowing air to pass in and out through its fibres, making it comfortable to wear.


• Coiled cellulose springs: Each cotton fibre is made up of 20-30 layers of coiled cellulose springs, giving it strength and flexibility.


• Moisture absorbing quality: Cotton has the ability to absorb moisture, making it ideal for making good quality clothes that are comfortable to wear in various climates.


• Natural twist for spinning: Cotton has a natural twist that makes it suitable for spinning into yarn, which is then used to make textiles.

Based on these characteristics, the fibre described in the question is Cotton.
