Assertion (A): A desizing stage is always followed by thorough washing.
Reason (R): The size is only broken into soluble fragments and must still be washed out of the cloth.
Answer: A
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the reason gives the necessity. Desizing is a solubilisation rather than a removal - nothing leaves the cloth until it is washed out. Poor washing is a common source of unlevel dyeing, since the residual dextrins remain on the fibre and interfere with the dye reaching it.
