Which of the following fibres catches fire least? (1) Nylon (2) Cotton (3) Rayon (4) Terricot

Description : Which of the following fibres catches fire least? (1) Nylon (2) Cotton (3) Rayon (4) Terricot

Last Answer : (2) Cotton Explanation: The fibre least prone to catch fire is cotton. Fabrics with more of the fiber surface area exposed to air have more oxygen available to support, burning and therefore burn more easily. Thus, thin, gauzy fabrics, lace, or brushed fabrics can be very flammable.
