Question

Why is a spinneret used to make nylon but is not needed to make cotton or wool fibres?

Answer 1

Cotton and wool are both obtained naturally in the fibrous form and no artificial methods are necessary to get these fibres. In contrast, nylon is a synthetic fibre obtained from plastics derived from petroleum. The plastic is first melted at high temperature and then forced out through a device with many holes in it known as a spinneret. Since, nylon is developed from plastic, a spinneret is needed to make nylon fibres.
