What is the difference between nylon and polyester yarn?

 

Nylon and polyester are both synthetic fabrics, but nylon production is more expensive, which results in a higher price for the consumer. Nylon also tends to be more durable and weather-resistant, which is why it is more likely to be used in outdoor apparel or gear. Both fabrics are flame retardant, but nylon is stronger, while polyester is more heat-resistant.

Both nylon and polyester are used in a wide variety of items, from apparel, to home furnishing, to consumer electronics, and much more.

Apparel

Polyester yarn is more widely used in apparel, found in almost every form of clothing. Typically nylon is only used for blouses, dresses, foundation garments, hosiery, lingerie, tights, underwear, raincoats, ski apparel, windbreakers, swimwear and cycle wear.
