Polyester is a synthetic fiber derived from petroleum-based products, known for its durability, resistance to shrinking and stretching, and its quick-drying properties. It’s one of the most widely used fibers in the textile industry, particularly popular in clothing, home furnishings, and of course, backpacks.

The creation of polyester involves a chemical reaction between acid and alcohol. In this process, ethylene glycol (alcohol) is combined with terephthalic acid to form the polymer known as polyethylene terephthalate (PET), the most common form of polyester. This substance is then extruded through a spinneret to form fibers, which are stretched, cooled, and cut or woven into the fabric.

Polyester’s appeal in the backpack industry lies in its strength, lightweight nature, and resistance to water and UV damage, making it a cost-effective choice for everyday and moderate use. Additionally, its ability to be recycled adds an eco-friendly aspect, aligning with growing sustainability trends in manufacturing.

What Are the Differences Between Polyester and Nylon Fabrics?

Polyester and nylon are both synthetic fibers, but they have distinct differences that affect their use, feel, and durability. Here are the key differences between polyester and nylon fabrics:

  1. Chemical Composition: Nylon is a polyamide, made from petroleum, and has a silkier, smoother texture. Polyester is a polymer produced from coal, air, water, and petroleum products, known for its durability and resistance to various chemicals.
  2. Moisture Absorption: Nylon absorbs more moisture than polyester, making it feel wetter when sweaty or in damp conditions. Polyester, on the other hand, wicks moisture away, making it more suitable for wet environments as it dries faster.
  3. Durability and Strength: Nylon is generally stronger and more abrasion-resistant than polyester. It’s more elastic, which allows it to maintain its shape and resist pilling better than polyester. However, polyester is more resistant to UV radiation and typically retains its color and strength over longer exposure to sunlight.
  4. Thermal Properties: Polyester has a higher melting point than nylon, making it more suitable for applications where high heat resistance is necessary.
  5. Water Resistance: While both fabrics can be treated for water resistance, nylon inherently has better water repellent properties than polyester, although it absorbs more water when untreated.
  6. Environmental Impact: Both materials are not biodegradable, but recycling methods have improved their environmental footprint. Polyester is more commonly recycled than nylon and is often made from recycled plastics like PET bottles.
  7. Cost: Polyester is generally less expensive to produce than nylon, making products made from polyester more affordable.
  8. Use in Backpacks and Gear: Polyester, known for its softness and moisture-wicking properties, is commonly chosen for everyday backpacks and gear. Nylon, valued for its high strength and abrasion resistance, is preferred for crafting more durable items, including heavy-duty backpacks and outdoor equipment.

Understanding these differences is crucial for choosing the right fabric for specific applications, whether for clothing, backpacks, or other textile products.

Which material offers better water resistance? nylon or polyester?

Considering the differences, it’s water resistance that often garners the most attention, so let’s delve into that.

When comparing the water resistance of nylon and polyester, nylon generally comes out on top due to its inherent hydrophobic properties. This characteristic makes nylon a popular choice for outdoor apparel and gear, as it is less likely to absorb moisture and can keep the contents dry in damp conditions. Nylon’s tightly woven fibers create a barrier against water penetration, enhancing its suitability for use in rain gear, outdoor equipment, and any application where water exposure is likely.

On the other hand, polyester, while also possessing some degree of water resistance, tends to absorb more water than nylon, resulting in longer drying times. This can be a drawback in environments where quick drying is beneficial. However, polyester’s water resistance can be significantly improved with the application of water-repellent coatings or treatments, which seal the fabric’s pores and prevent water absorption.

In the context of backpacks and gear, the choice between nylon and polyester for water resistance depends on the specific needs of the user. For activities that involve heavy exposure to water or require quick drying, nylon is the preferred material. For less demanding situations or when cost is a major factor, polyester with appropriate treatments can be an adequate and more budget-friendly option.

Both materials are versatile and can be engineered to enhance their water-resistant qualities, making them adaptable to a wide range of applications. Ultimately, the decision between nylon and polyester will depend on the intended use, environmental conditions, and specific requirements for water resistance in the gear or backpacks being designed.

Is nylon stronger than polyester?

Yes, nylon is generally considered stronger than polyester. Nylon’s superior tensile strength, elasticity, and abrasion resistance make it a more durable choice compared to polyester, especially for applications where strength and durability are crucial, such as in outdoor gear or heavy-duty backpacks. However, the specific use case and the type of nylon or polyester fabric can influence their relative strength.

How do the costs of nylon and polyester compare?

Typically, polyester is less expensive than nylon. The lower cost of polyester is one reason it’s so widely used in various industries, including textiles and apparel. The production process for polyester is more cost-effective, which is reflected in the final price of products made from it. Nylon, known for its superior strength and durability, often has a higher manufacturing cost, leading to higher prices for end products. However, the exact cost can vary based on the quality, weave, and treatment of the fabrics.

Here are some examples to illustrate the cost differences between polyester and nylon across various products:

  1. Backpacks: School backpacks or basic daypacks are often made from polyester, providing a cost-effective solution for consumers. In contrast, high-performance backpacks designed for hiking or military use typically use nylon, which, despite its higher cost, is preferred for its strength and longevity.
  2. Outdoor Equipment: Tents, tarps, and other outdoor equipment offer a clear example of this cost dynamic. Polyester versions are generally more affordable and serve well in less demanding conditions, while nylon variants, priced higher, are favored for extreme environments due to their robustness.
  3. Clothing: Polyester is commonly used in affordable everyday wear, such as t-shirts, leggings, and casual dresses. Nylon, with its higher cost, is often reserved for specialized apparel like high-end activewear or outdoor gear, where its durability and resistance to elements are crucial.
  4. Automotive Industry: In vehicle interiors, polyester fabrics are often used for trunk organizers,sear organizers, seat protectors, carpets, and headliners as a budget-friendly option. Nylon, although more costly, is utilized in areas requiring more resilience, like airbags and seatbelts.

How eco-friendly are nylon and polyester when making backpacks?

Nylon and polyester, both synthetic materials derived from petroleum, are not inherently eco-friendly. Their environmental impact is largely determined by the production process and the material’s lifecycle.

Polyester, often referred to as RPET (Recycled Polyethylene Terephthalate) when made from recycled materials, is considered more eco-friendly in backpack manufacturing. It can be made from recycled plastics, such as PET bottles. This recycling process helps reduce waste and the consumption of new resources.


Nylon, on the other hand, has a more energy-intensive production process, making it less eco-friendly initially. However, efforts to recycle nylon are increasing, and using recycled nylon significantly lowers its environmental impact.

The overall eco-friendliness of nylon and polyester backpacks also depends on their durability and longevity. A more durable backpack that lasts longer can be more eco-friendly over its lifecycle, as it reduces the need for frequent replacements.

Is Nylon or Polyester Better?

After delving into the characteristics, uses, and environmental considerations of nylon and polyester, you might be wondering: which is better? The answer isn’t straightforward. Nylon’s strength, durability, and water resistance make it superior for outdoor and demanding applications. However, polyester’s cost-effectiveness, UV resistance, and quick-drying properties cannot be overlooked for everyday use and less intensive environments.

Ultimately, the “better” material depends on your specific needs, preferences, and the particular demands of the backpack’s intended use. Whether you prioritize durability, cost, environmental impact, or specific performance features will guide your choice between nylon and polyester for your next backpack.
