How to Wash Nylon Fabric: The Complete Care Guide

Nylon is one of the most durable and versatile synthetic fabrics around — found in everything from windbreakers and swimwear to backpacks and hosiery. It's generally easy to care for, but a few simple mistakes can cause pilling, static, or damage. Here's exactly how to wash nylon fabric the right way.

Can You Machine Wash Nylon?

Yes — most nylon garments are machine washable. Nylon is a strong, resilient synthetic fiber that handles washing well, as long as you use the right settings. The main thing to avoid is high heat, which can warp, shrink, or damage nylon fibers.

What You'll Need

A gentle laundry detergent
A mesh laundry bag for delicate nylon items
Access to a washing machine or sink

💡 Pro tip: Always wash delicate nylon items — like athletic wear, swimwear, or lingerie — inside a mesh laundry bag like this one from Polecasa. It prevents snagging, stretching, and friction damage during the wash cycle.

Step-by-Step: How to Machine Wash Nylon

Check the care label — always start here. Some structured nylon items like bags or outerwear may have specific care requirements.
Turn the garment inside out — this protects the outer surface from friction and reduces pilling.
Place in a mesh laundry bag — essential for delicate nylon pieces.
Select cold or warm water — use a maximum of 86°F / 30°C. Never wash nylon in hot water.
Choose a gentle or delicate cycle — less agitation means less wear on the fibers.
Use a gentle detergent — a non-toxic, enzyme-based detergent like Puracy Laundry Detergent is ideal for nylon. Avoid detergents with bleach or optical brighteners.
Skip the fabric softener — fabric softener coats synthetic fibers and can reduce nylon's performance properties over time.

How to Hand Wash Nylon

Hand washing is the gentlest option for delicate nylon items like hosiery, lingerie, or lightweight athletic wear.

Fill a basin with cool or lukewarm water
Add a small amount of gentle detergent and mix well
Submerge the garment and gently swish for 2–3 minutes
Rinse thoroughly with cool water until no detergent remains
Gently press out excess water — never wring nylon

How to Dry Nylon

Air drying is best — hang or lay flat away from direct sunlight
If using a dryer, use the lowest heat or air-only setting
Remove promptly from the dryer to prevent wrinkles
Never use high heat — nylon can warp, shrink, or melt under high temperatures
Nylon dries very quickly — most items are ready within 1–2 hours of air drying

Common Mistakes to Avoid When Washing Nylon

❌ Washing in hot water
❌ Using high heat in the dryer
❌ Using bleach — it weakens and discolors nylon fibers
❌ Wringing the fabric — this distorts the shape
❌ Washing with rough fabrics like denim or towels that cause friction
❌ Using fabric softener on performance nylon

Special Nylon Items: Extra Care Tips

Nylon windbreakers and outerwear: Machine wash on gentle in cold water. Re-apply a DWR waterproofing treatment after washing to restore water repellency — washing removes the original coating over time.

Nylon swimwear: Rinse in cold water immediately after use to remove chlorine or salt. Hand wash with gentle detergent and air dry flat.

Nylon backpacks and bags: Spot clean where possible. If machine washing, remove all contents, place in a large mesh bag, and wash on gentle in cold water.

Frequently Asked Questions

Does nylon shrink in the wash?
Pure nylon is very resistant to shrinking in cold or warm water. High heat in the dryer can cause some shrinkage or distortion. Always use low heat or air dry.

Can you wash nylon in warm water?
Yes — warm water up to 86°F / 30°C is safe for most nylon. Cold water is the safest option.

How often should you wash nylon clothes?
Activewear nylon should be washed after every use. Outerwear and bags can go longer between washes depending on use.

Can you iron nylon?
Only on the very lowest heat setting with a pressing cloth. A garment steamer is a much safer option for removing wrinkles from nylon.

Why does nylon get static?
Like all synthetic fabrics, nylon builds up static electricity through friction. Use wool dryer balls instead of dryer sheets, and dry on low heat or air dry to minimize static.

The Bottom Line

Washing nylon is straightforward: cold or warm water, gentle cycle, low heat drying. Protect delicate pieces with a mesh laundry bag, use a gentle enzyme detergent like Puracy, and skip the fabric softener. Do that consistently and your nylon clothes and gear will stay in great condition for years.
