Nylon vs. Polyester: Which is Better?

Updated: Jul 4

When it comes to synthetic fibers, two names often come up: nylon vs polyester.

Both materials have carved out significant niches in various industries due to their versatility, durability, and performance characteristics.

However, when faced with the question of which is better, the answer isn't straightforward. It depends on the specific application, the required properties, and the environmental impact considerations. In this blog post, we'll delve into the characteristics, advantages, and disadvantages of nylon and polyester to help you make an informed decision.

Understanding Nylon vs Polyester: Which is better?


What is Nylon?


Nylon, a polyamide, was the first synthetic fiber to be fully synthesized from petrochemicals. Developed by DuPont in the 1930s, nylon revolutionized the textile industry. It is known for its strength, elasticity, and abrasion resistance. Nylon fibers are used in a wide range of products, from clothing and upholstery to industrial applications like ropes and conveyor belts.


What is Polyester?


Polyester is a category of polymers that contain the ester functional group in their main chain. Introduced in the 1940s, polyester has become one of the most widely used synthetic fibers. It is valued for its resistance to stretching and shrinking, quick-drying properties, and resistance to most chemicals. Polyester fibers are used extensively in textiles, home furnishings, industrial fabrics, and packaging.


Comparing Nylon and Polyester


Durability and Strength




- High Tensile Strength: Nylon is incredibly strong, making it suitable for heavy-duty applications.

- Elasticity: Nylon's elasticity helps it return to its original shape after stretching, which is beneficial for applications requiring flexibility.

- Abrasion Resistance: Nylon is highly resistant to abrasion, making it ideal for products subjected to frequent wear and tear.




- Good Strength: While not as strong as nylon, polyester is still very durable.

- Low Elasticity: Polyester is less elastic than nylon but maintains its shape well.

- Abrasion Resistance: Polyester is also resistant to abrasion, though to a slightly lesser extent than nylon.


Moisture Absorption




- High Moisture Absorption: Nylon absorbs more water compared to polyester, which can lead to longer drying times. This property makes it less ideal for moisture-wicking applications.




- Low Moisture Absorption: Polyester absorbs very little water, making it an excellent choice for moisture-wicking fabrics and quick-drying applications.


Comfort and Feel




- Soft and Smooth: Nylon tends to have a softer and smoother texture, providing a more comfortable feel against the skin.

- Breathability: While breathable, nylon can become less comfortable when wet due to its higher moisture absorption.




- Crisp and Firm: Polyester fabrics often feel crisper and firmer than nylon.

- Breathability: Polyester is less breathable than nylon but remains comfortable due to its moisture-wicking properties.


Environmental Impact




- Energy-Intensive Production: The production of nylon is energy-intensive and involves the release of nitrous oxide, a potent greenhouse gas.

- Non-Biodegradable: Nylon is non-biodegradable, contributing to long-term environmental pollution.




- Energy-Efficient Production: Producing polyester requires less energy than nylon, making it somewhat more environmentally friendly.

- Recyclability: Polyester can be recycled more efficiently than nylon, with many recycling programs converting used polyester into new fibers.






- Higher Cost: Nylon is generally more expensive to produce due to its complex manufacturing process and higher raw material costs.




- Lower Cost: Polyester is typically cheaper to produce, making it a more cost-effective option for many applications.


Applications of Nylon and Polyester


Clothing and Textiles




Nylon is commonly used in:


- Activewear and sportswear due to its strength and flexibility.

- Hosiery and lingerie for its smooth texture and elasticity.

- Outerwear and raincoats for its water-resistant properties.




Polyester is often found in:


- Everyday clothing, including shirts, trousers, and dresses.

- Sportswear and activewear for its moisture-wicking abilities.

- Home textiles like curtains, beddings, and upholstery.


Industrial Uses




Nylon's strength and durability make it suitable for:


- Ropes and fishing nets.

- Conveyor belts and industrial hoses.

- Automotive parts and components.




Polyester is used in:


- Industrial fabrics and conveyor belts.

- Hoses and ropes.

- Packaging materials like PET bottles and films.


Which is Better: Nylon or Polyester?


The choice between nylon and polyester ultimately depends on the specific requirements of the application. Here are some guidelines to help you decide:


- Choose Nylon If You Need:

  - High tensile strength and durability.

  - High elasticity and flexibility.

  - A softer, smoother texture.


- Choose Polyester If You Need:

  - Low moisture absorption and quick-drying properties.

  - Cost-effectiveness and recyclability.

  - A crisper, more firm fabric.




Nylon and polyester each have their strengths and weaknesses, making them suitable for different applications. Nylon offers superior strength and a smoother texture, making it ideal for demanding industrial uses and high-performance clothing. Polyester, on the other hand, provides excellent moisture-wicking properties and cost-effectiveness, making it a versatile choice for everyday clothing and various industrial applications.


Understanding the specific needs of your application is key to choosing the right material. By considering factors such as durability, moisture absorption, comfort, environmental impact, and cost, you can make an informed decision that maximizes the benefits of either nylon or polyester.
