Is polyester stronger than polyamide

The common thing between polyamide and polyester is both are synthetic fibers fall under class man made fibers.

Nylon is commonly known as polyamide. Developed by Dupoint. Polyamide (nylon) is first engineering thermoplastic. It is one of many hetrochain thermoplastics, which as atoms other than C in the chain. It is created when condensation reaction occurs between aminoacids, dibasicacids and diamines.

Polyester is any long chain synthetic polymer, where 85% (of weight) of the polymer is an ester and therphthalic acid. Most polyestr made from polyethylene terephtalate. Properties varies depending on their composition web structuring and processing. Its the inexpensive fiber which brought reveloution in textile industry.
