Difference between Nylon and Polyester

Main difference

The main difference between nylon and polyester is that nylon is low-maintenance and has strength, toughness, and good stretch, while polyester is more breathable and conspicuously waterproof.

nylon vs. polyester

Nylon in its structure is mainly made up of nitrogen atoms, while polyester has no nitrogen atoms in its structure. Due to the presence of amide groups, nylon is also called polyamide, while polyester is also called polyethylene terephthalate (PET). Diamine and dicarboxylic acid monomers are involved in the production of nylon; on the other hand, diol and dicarboxylic acid monomers are involved in the production of polyester. Nylon is manufactured as a liquid, spun, and mechanically dried into individual fibers; on the contrary, the polyester is manufactured as spun into the yarn from the chemical solution. Nylon has low moisture absorption; in contrast, polyester is wrinkle resistant. Nylon’s durability is exceptionally strong, resistant to damage from oil and many chemicals, and resistant to abrasion, while polyester is strong. Shrinkage and stretching, resistant to wet chemicals, etc. Nylon melts then burns rapidly during combustion; on the other hand, polyester melts and burns at the same time. The environmental impact of nylon is that most nylon is made from the unavoidable by-products of oil refineries, while polyester is not biodegradable but can be recycled. Nylon is light, soft, warm, smooth, and quick-drying; in contrast, polyester is light, soft, and quick-drying. The nail can be classified as a thermoplastic polymer; on the other hand, Polyester can be classified as a thermoplastic or a thermosetting polymer. The environmental impact of nylon is that most nylon is made from the unavoidable by-products of oil refineries, while polyester is not biodegradable but can be recycled. Nylon is lightweight, soft, warm, smooth, and quick-drying; In contrast, polyester is lightweight, soft, and quick-drying. The nail can be classified as a thermoplastic polymer; On the other hand, polyester can be classified as a thermoplastic or a thermosetting polymer.

What is nylon?

A common name used for molecules of polymer class that is composed of polyamides is called nylon. Due to their thermal properties, they are known as thermoplastics, and this group of polymers includes plastics. Due to the presence of amide groups nylon is also called as polyamide. The monomers diamines and dicarboxylic acids are involved in the production of nylon. Symmetrical backbones and semi crystalline structures make nylons very good fibers. Nylon gets its name according to the number of carbon atoms in diamine and dicarboxylic acids. Eg, nylon 6,6 has six carbon atoms in diamine and six carbon atoms in dicarboxylic acids. Generally, nylon is tough material. But mostly nylon is light-weight, smooth, warm, soft, and quick-drying Nylon is manufactured as a liquid, mechanically spun and dried into individual fibers. The durability of nylon is exceptionally strong, resistant to damage from oil and many chemicals, and abrasion-resistant but has low moisture absorbency. Nylon melts then burn rapidly during fuel. The environmental impact of nylon is that most nylon made from unavoidable oil refinery byproducts.

What is polyester?

A common name used to define long chain polymers collected from ester groups on the main chain is called polyester. They are chemically composed of approximately 85% by weight of dihydric alcohol, ester and terephthalic acid. In other words, the reaction between alcohols and carboxylic acids that produce esters causes the formation of a polyester. The polyester is manufactured as spun into the yarn from the chemical solution. The monomers diols and dicarboxylic acids are involved in the production of polyester. Polyester is a durable and extremely strong material, resistant to shrinking and stretching, resistant to wet chemicals, etc. Polyester is widely used in the food industry, textile, etc. Polyester melts and burns at the same time. Polyester is lightweight

Types

  • Saturated polyesters: composed of saturated skeletons. These are less reactive or not.
  • Unsaturated polyesters: Composed of vinyl unsaturation, so they are very reactive.

Key differences

  1. Nylon in its structure is mainly made up of nitrogen atoms, while polyester has no nitrogen atoms in its structure.
  2. Due to the presence of amide groups, nylon is also called polyamide, while polyester is also called polyethylene terephthalate (PET).
  3. Diamine and dicarboxylic acid monomers are involved in the production of nylon; on the other hand, diol and dicarboxylic acid monomers are involved in the production of polyester.
  4. Nylon is manufactured as a liquid, spun, and mechanically dried into individual fibers; on the contrary, the polyester is manufactured as spun into the yarn from the chemical solution.
  5. Nylon has low moisture absorption; In contrast, polyester is wrinkle resistant.
  6. The durability of nylon is exceptionally strong, resistant to damage from oil and many chemicals, and resistant to abrasion, while polyester is strong, resistant to shrinkage and stretching, resistant to wet chemicals, etc.
  7. The environmental impact of nylon is that most nylon is made from the unavoidable by-products of oil refineries, while polyester is not biodegradable but can be recycled.
  8. Nylon melts and then burns rapidly during flammability; on the other hand, polyester melts and burns at the same time.
  9. Nylon is lightweight, soft, warm, smooth, and quick-drying; In contrast, polyester is lightweight, soft, and quick-drying.
  10. Nylon is a thermoplastic polymer of the category; on the other hand, polyester can be a thermoplastic or thermosetting polymer in the category.

Final Thought

The above discussion concludes that nylon is low maintenance and has strength, toughness and good stretch, while polyester is more breathable and conspicuously waterproof.
