Key Differences
Polyester: Composed of ester functional groups in its polymer chain. Polyamide: Contains amide functional groups (CONH) in its polymer chain.
Polyester: Known for its resistance to wrinkles, moisture-wicking properties, and durability. Polyamide: Recognized for its strength, flexibility, and abrasion resistance.
Polyester: Generally more affordable and widely available in various forms. Polyamide: May be relatively more expensive and commonly used in specialized applications.

Polyester
A synthetic resin in which the polymer units are linked by ester groups, used chiefly to make synthetic textile fibres.
Polyamide
A polyamide is a polymer with repeating units linked by amide bonds.Polyamides occur both naturally and artificially. Examples of naturally occurring polyamides are proteins, such as wool and silk.
Polyester
Any of numerous synthetic polymers produced chiefly by reaction of dicarboxylic acids with dihydric alcohols and used primarily as light, strong, weather-resistant resins in boat hulls, textile fibers, adhesives, and molded parts.
Polyamide
A synthetic polymer of a type made by the linkage of an amino group of one molecule and a carboxylic acid group of another, including many synthetic fibres such as nylon.
Polyester
A wrinkle-resistant fabric of fibers made from any of these resins.
Polyamide
A polymer containing repeated amide groups, as in various kinds of nylon.

Common Curiosities
What is polyester made from?
Polyester is made from ester monomers, usually derived from petroleum-based chemicals.
Can polyester fabrics be ironed?
Yes, polyester fabrics can be ironed at low to medium temperatures to remove wrinkles.
What is the primary characteristic of polyamide (nylon) fabrics?
Polyamide fabrics, such as nylon, are known for their strength, flexibility, and resistance to abrasion.
What are some common applications of polyamide engineering plastics?
Polyamide engineering plastics are used in automotive parts, gears, and industrial components due to their durability and heat resistance.
Is polyester environmentally friendly?
While polyester can be recycled, it is not considered as eco-friendly as natural fibers like cotton.
Can polyamide materials be recycled?
Some types of polyamide, especially nylon, can be recycled into new products.
What are the advantages of using polyester in clothing?
Polyester offers wrinkle resistance, moisture-wicking properties, and durability, making it suitable for sportswear and everyday clothing.
Is polyamide fabric suitable for outdoor activities?
Yes, polyamide fabrics like nylon are commonly used in outdoor clothing and gear because of their toughness and moisture-wicking properties.
What is PET, and how is it related to polyester?
PET (polyethylene terephthalate) is a type of polyester often used in the production of plastic bottles for beverages.
What is the difference between polyamide and polyester in terms of feel and texture?
Polyamide fabrics like nylon tend to have a smoother and softer feel compared to the often sleek and shiny texture of polyester.
