What is carding of wool? How is woollen yarn obtained from carded wool?

Answer:

The wool fibres are dried and then disentangled. They are then combed and straightened by a cardinal machine. This is called carding.                                                                                                                                     In the cardinal machine, the disentangled woollen fibres are passed between a pair of rotating cylinders covered with a material called carding cloth, which contains fine, pliable wire teeth. The wool emerges from the rollers in the form of thin wire called web.
