The fibre used for making cloth should have certain characteristics like it should be light in weight and should not have a dull surface, i.e. should be shiny/lustrous. It should be strong/durable and should possess some elasticity. These characteristics make nylon fibre a suitable choice for making cloth.
High tensile strength, easy moulding and being a regenerated fibre are also the characteristics of nylon, but these are not the requisite properties for using it make cloth.
