Question

Nylon clothes should be ironed on low heat?

Answer 1

Generally, nylon is a silky smooth thermoplastic (which means it melts and turns runny when you heat it up, generally at around 260°C or 500°F) that's strong, tough, and durable (it's reasonably wear-proof and resists sunlight and weathering). Since it's a synthetic plastic, it's highly resistant to attack from such natural nasties as molds, insects, and fungi. It's waterproof (hence its use in umbrellas and waterproof clothes) and fast-drying because (unlike with natural fabrics like cotton or wool) water molecules can't easily penetrate the outer surface. Although reasonably resistant to quite a lot of everyday substances, nylon will dissolve in phenol, acids, and some other harsh chemicals.
