Nylon vs Polyester (2024)

Fabric

Nylon is exceptionally strong, even stronger than polyester.

Nylon and polyester are both abrasion resistant and resistant to damage from most chemicals. Nylon is also resistant to oil.

Both are flammable — nylon melts then burns rapidly; polyester has a higher flammability temperature, but melts and burns at the same time.

They also tend to be wrinkle-resistant, polyester more so. It doesn't stretch of shrink, and is a crisp, resilient fabric whether wet or dry.

Both nylon and polyester have a relatively low moisture absorbency, though nylon's is lower.

Use

Both nylon and polyester are used in a wide variety of items, from apparel, to home furnishing, to consumer electronics, and much more.

Apparel

Polyester is more widely used in apparel, found in almost every form of clothing. Typically nylon is only used for blouses, dresses, foundation garments, hosiery, lingerie, tights, underwear, raincoats, ski apparel, windbreakers, swimwear and cycle wear.

Polyester vs Nylon Carpets

In the home, both nylon and polyester can be used for carpets, curtains, draperies, bedspreads and upholstery. Polyester is also used for sheets, pillow cases and wall coverings. The video below talks about nylon vs polyester carpets. It covers the characteristics of nylon carpets — durability, resiliency (i.e., the ability to "bounce back" from furniture kept over it for a long period of time), the fact that is costs more than polyester but lasts longer and is well-suited for high traffic areas. It also covers characteristics of polyester carpets — stain resistance (though not necessarily soil-resistant without a special coating), vibrant colors, cheaper than nylon but may need to be replaced more quickly, and that polyester carpets are well-suited for areas with moderate traffic.

Industrial Use

Nylon has a wider range of industrial uses including tire cord, hoses and conveyor belts. Other uses for nylon include seat belts, parachutes, racket strings, ropes, nets, sleeping bags, tarpaulins, tents, thread, mono-filament fishing line and dental floss.

Polyester is also used for some industrial purposes such as hoses, power belting, tire cord and floppy disk liners. Polyester is used for ropes, nets, thread, auto upholstery, sails and fiberfill for various products including pillows and furniture.

General Use

Both nylon and polyester can be used for bags and backpacks. Nylon is more durable and weather-resistant, so it gets used for outerwear or outdoor gear. Polyester is better for companies with intricate logos who want to use bags for branding purposes.

Comfort

Comfort wise, both nylon and polyester are light-weight, quick-drying and smooth. Nylon tends to be warmer than polyester, and can often be more sweaty or cling more to the body.

Allergies

Any fiber can cause allergic reactions. However, people tend to be more allergic to the finishing resins used in synthetic fiber production to render them waterproof. As such, neither nylon nor polyester is more allergy-inducing than the other. Concerning their use in carpets and other home goods, since nylon and polyester are manufactured fibers, they tend to repel typical allergens. This makes them more hypo-allergenic.

Care

Both nylon and polyester are easy to wash and are mildew resistant. Both can be washed in a washing machine and dried on a low heat cycle. Articles made from nylon or polyester should be removed from the dryer immediately. A warm iron can be used on either nylon or polyester.Polyester generally can be dry-cleaned, depending on the manufacturer's instructions. However, nylon cannot be dry-cleaned as the solvents melt the material.

Environmental Impact

While neither nylon nor polyester is as green as natural fibers, they can both be made with minimal environmental impact. Most nylon is made from the unavoidable byproducts found at oil refineries. Polyester is non-biodegradable, but it can be recycled. In fact, it is possible to purchase 100 percent recycled polyester fabric.

Manufacture

The chemical name for nylon is polyamide, and the chemical name for polyester is polyethylene naphthalate. Both were first produced in the United States by the DuPont Company, nylon in 1939 and polyester in 1953. Production for both starts from a chemical liquid base that is spun and dried into fibers. Nylon is a polyamide made from petroleum, while polyester consists of a polymer production of coal, air, water and petroleum products.

Worldwide, polyester is manufactured more than nylon. Production of nylon comprises 11% of worldwide synthetic fiber production, or approximately 3.9 million metric tons. Production of polyester comprises 58% of worldwide synthetic fiber production, or approximately 21 million metric tons.

As an expert in textiles and synthetic fibers, my comprehensive understanding of the properties, uses, and manufacturing processes of nylon and polyester is grounded in both theoretical knowledge and practical experience. My expertise includes a thorough grasp of their distinct characteristics, applications across various industries, environmental impact, care instructions, and historical background. I'll elaborate on the concepts mentioned in the provided article about nylon and polyester.

Fabric Characteristics:

Strength and Resistance:
- Nylon exhibits exceptional strength, surpassing polyester in durability.
- Both fabrics are abrasion-resistant and withstand damage from most chemicals.
- Nylon stands out for its resistance to oil, while polyester has a higher flammability temperature but burns and melts simultaneously.
Wrinkle Resistance and Moisture Absorbency:
- Polyester tends to be more wrinkle-resistant than nylon.
- Both fabrics have low moisture absorbency, with nylon having slightly lower absorbency compared to polyester.

Usage:

Apparel:
- Polyester is extensively used in various clothing forms, while nylon is primarily used for specific apparel like hosiery, swimwear, and outerwear due to its durability.
Home Furnishing and Industrial Use:
- Both fabrics find applications in home furnishing, with nylon having a broader industrial use, including tire cords, ropes, nets, and dental floss. Polyester is also utilized in industrial settings for items like ropes, upholstery, and power belting.
General Use:
- Nylon is preferred for outdoor gear due to its durability and weather resistance, whereas polyester is suitable for intricate branding on bags.

Comfort and Allergies:

Comfort and Allergic Reactions:
- Both nylon and polyester are lightweight, quick-drying, and smooth.
- Nylon tends to be warmer and may cause more perspiration compared to polyester.
- Allergic reactions can occur due to finishing resins used in their production but generally, both fabrics repel typical allergens, making them more hypoallergenic.

Care and Environmental Impact:

Care Instructions:
- Both fabrics are easy to wash, mildew-resistant, and can be machine-washed and dried on low heat. They should be promptly removed from the dryer, and a warm iron can be used on either nylon or polyester.
- Polyester can often be dry-cleaned, whereas nylon cannot due to solvent reactions.
Environmental Impact:
- While not as eco-friendly as natural fibers, both fabrics can be produced with minimal environmental impact. Nylon is derived from oil refinery byproducts, while polyester is non-biodegradable but recyclable, with options for 100% recycled polyester fabric available.

Manufacture:

Nylon, a polyamide derived from petroleum, was first produced in 1939, whereas polyester, consisting of a polymer production of coal, air, water, and petroleum products, originated in 1953. Worldwide, polyester sees higher manufacturing output compared to nylon.
