Main Difference between PET and PE

The main difference between nylon and polyester is that n​ylon has low maintenance and having strength, resistance, and good elasticity, whereas polyester is more breathable and shines for being water-resistant.

 

Nylon in its structure is mainly composed of nitrogen atoms whereas polyester has no nitrogen atoms in its structure. Due to the presence of amide groups nylon is also called as polyamide, while polyester is also called polyethylene terephthalate (PET). The monomers diamines and dicarboxylic acids are involved in the production of nylon; on the other hand, the monomers diols and dicarboxylic acids are involved in the production of polyester. Nylon is manufactured as a liquid, mechanically spun and dried into individual fibers; on the contrary, polyester is manufactured as spun into the thread from the chemical solution. Nylon has low moisture absorbency; conversely, polyester is wrinkle resistant. The durability of nylon is exceptionally strong, resistant to damage from oil and many chemicals, and abrasion-resistant, whereas polyester is strong, resistant to shrinking and stretching, resistant to moist chemicals, etc. Nylon melt then burns rapidly during combustion; on the flip side, polyester melts and burn at the same time. The environmental impact of nylon is that most nylon made from unavoidable oil refinery byproducts, while polyester is non-biodegradable but can be re-cycled. Nylon is light-weight, smooth, warm, soft, and quick-drying; on the contrary, polyester is light-weight, smooth, and quick drying. Nylon can be classified as a thermoplastic polymer; on the other hand, polyester can be classified as either thermoplastic or a thermoset polymer.
