The short answer
Nylon is a type of polyamide. All nylon is polyamide, but not every polyamide is nylon. On clothing labels, “polyamide” almost always refers to nylon, so for shopping purposes the two terms are usually treated as the same fabric.
What polyamide means
Polyamide is a chemical term for polymers whose repeating units are joined by amide linkages. It is a broad family that includes:
- Nylons, the synthetic polyamides used in clothing, carpets, ropes and many molded plastic parts.
- Aramids, such as the fibers sold under brand names like Kevlar and Nomex, used in protective gear and industrial products.
- Natural polyamides. Proteins such as wool and silk contain amide linkages, so they are sometimes described as natural polyamides in a chemical sense. This is rarely how the word is used in a fashion or textile context.
Where nylon fits
Nylon was developed in the 1930s and was among the first fully synthetic fibers sold on a large scale. Common textile types are often called nylon 6 and nylon 6,6, which differ in their chemical makeup. Both are used in apparel and other products.
Nylon fabric is known for strength, abrasion resistance, some elasticity, low water absorption and quick drying. For a fuller look at the benefits and drawbacks, see our pillar guide: is nylon good or bad.
Why clothing labels say polyamide
In many regions, textile labeling rules require a generic fiber name. In Europe, for example, “polyamide” is the standard generic name on labels, while in the United States “nylon” is the standard term. Brands may also use “nylon” in their marketing while the tag says polyamide. So a “polyamide” tag on a swimsuit, legging or jacket is generally describing a nylon-type fabric.
Other polyamides
Outside everyday clothing, the differences matter more:
- Aramid fibers are far more heat-resistant and are used for protective clothing and ballistic materials, not casual wear (see the most durable fabric).
- Engineering plastics made from nylon are used in gears, fasteners and automotive parts.
If you are shopping for apparel, these distinctions rarely affect your decision.
Does it matter for the fabric you buy?
Mostly no. What changes how a garment feels and performs is:
- the exact nylon type and yarn thickness
- the weave or knit
- any blend, such as nylon with elastane for stretch (see uses of Lycra fabric) or with cotton for comfort
- finishes, such as water-repellent coatings

Care
Care guidance for polyamide and nylon is the same because they are the same fabric in most garments.
- Wash in cool or warm water and follow the label.
- Dry on low heat or air-dry.
- Use a low iron setting if needed, since high heat can damage the fibers.
- Consider a fiber-catching wash bag, as synthetic fabrics can shed microfibers.
Plastic and safety questions
Is nylon 100% plastic? Nylon is a synthetic polymer, which places it in the broad chemical category of plastics, but it is processed into fibers and textiles rather than molded objects.
What is the unhealthiest fabric to wear? No fabric can be ranked this way with confidence. Reactions depend on dyes, finishes, fit and individual sensitivity. Anyone with a skin condition or concerns should consult a healthcare professional.
FAQ
Is nylon a type of polyamide?
Yes. Nylon is the best-known family of synthetic polyamides.
Is polyamide a good material?
It is a good choice where strength, flexibility and quick drying matter, such as activewear, swimwear (see sewing swimsuit fabric) and hosiery. It is less ideal where you want maximum breathability.
Is polyamide natural or synthetic?
Most polyamide fabric on clothing labels is synthetic. Natural polyamides such as silk and wool exist in chemical terms but are labeled by their own names.
