Class teacher gave four different samples of fibres to
four students. Ria has fibre H, which is obtained from
plant that grows best in alluvial soil in warm and humid
climates. Fibre I given to Sumit gives smell of burning
hair on being burnt and has ability to trap air and heat,
while fibre J given to Kanika, is a fibre obtained from
an insect. Fibre K given to Rahul burns with smell of
burning plastic. Identify the fibres H, I, J and K and
select the correct option regarding them.
AFibre H is the cheapest vegetable fibre and is also known as golden fibre.
BFibre I is obtained from passion vine and can be worn both in summers and winters.
CFibre J does not absorb water at all hence is used in making raincoats.
DFabric made of fibre K can absorb sweat, thus is comfortable to wear in hot and humid weather.
Given images show various steps in processing of cotton fibre into fabric. Arrange these steps in correct sequence.
