Is Nylon Fabric More Expensive Than Polyester? A Sourcing Guide
Yes, nylon knit fabric is more expensive than polyester knit fabric at the same weight and construction. The premium comes from raw material chemistry, not supplier markup. As a working reference, nylon 6 knits typically carry a higher quotation than comparable polyester knits at the same weight — a spread that tracks the nylon 6 chip versus PET chip gap. Polyester offers lower cost and faster drying; nylon provides superior stretch recovery and durability, making it ideal for high-abrasion activewear. The real sourcing question is not which fiber is cheaper per meter, but which is cheaper per wear and per returned unit.
Short Answer: Is Nylon More Expensive Than Polyester?
Yes — nylon knit fabric carries a price premium over comparable polyester knit at the same weight and construction. The premium is driven by raw material chemistry, not by supplier markup. Polyester offers lower cost and faster drying; nylon offers superior stretch recovery and durability for high-abrasion activewear. The real question is not which is cheaper per meter but which is cheaper per wear and per returned unit.
For a sourcing manager building a BOM, the per-meter gap is real and consistent. Nylon 6 feedstock (caprolactam) trades in a different upstream market than polyester’s PTA and MEG, and that difference flows directly into the fabric price. But the decision framework should not stop at the invoice line. A nylon-spandex swim knit that survives repeated pool exposure without sagging may deliver a lower cost per wear than a cheaper polyester alternative that loses shape after repeated washing. Conversely, a polyester jersey for a promotional tee wins on cost per wear because the garment’s expected life is short and the performance bar is low.
This guide breaks down the price drivers, compares performance and cost per wear side by side, and gives you a negotiation checklist to reduce the nylon penalty without sacrificing the performance your program needs. For a deeper fiber-level comparison, see our polyester vs nylon knit fabric guide.
What Actually Drives the Nylon–Polyester Price Gap
Raw material feedstock is the dominant driver: nylon 6 derives from caprolactam, while polyester derives from PTA and MEG — different upstream markets with different volatility profiles. Because raw material is the largest visible cost layer, feedstock differences dominate the final price. The cost stack below is typical for our programs, based on YXX internal costing rather than a third-party index.
| Cost Layer | Share of Total Fabric Cost (YXX internal costing) |
|---|---|
| Raw material | 45–55% |
| Processing (knitting, dyeing, finishing) | 20–25% |
| Logistics | 8–12% |
| Compliance | 5–8% |
Dyeing economics also matter. Nylon dyes at lower temperatures with different energy and chemical profiles than disperse-dyed polyester. That can mean lower energy per batch for nylon, but the chemicals and dye selection often cost more, and the shade-matching window is tighter. Polyester dyeing runs hotter and requires more energy, but the process is highly standardized and forgiving at scale.
Finishing and yield add another layer. Nylon’s higher moisture regain and hand feel often require different finishing routes — sometimes softer, sometimes more dimensional stabilization — which affects yield per meter and the effective GSM you pay for. If you buy on weight, a nylon knit that requires more finishing passes can carry a hidden cost that does not show up in the quoted price per kilogram.
Finally, supply chain structure matters. Nylon knit capacity is less commoditized than polyester, so fewer mills compete on the same construction. That reduces price pressure and keeps the premium sticky. For a full breakdown of how these layers interact, see our textile sourcing cost control guide.
Nylon vs Polyester Knit: Cost and Performance Compared
Nylon costs more per meter but can cost less per wear in high-abrasion, high-stretch programs. Polyester wins on upfront price and drying speed. The table below compares the two fibers across the drivers that matter most to a BOM decision.
| Cost / Performance Driver | Nylon Knit | Polyester Knit | Cost-per-Wear Implication |
|---|---|---|---|
| Raw material feedstock | Caprolactam (nylon 6) | PTA + MEG | Nylon higher upfront; polyester more volatile to oil prices |
| Dyeing energy / temperature | Lower temperature, tighter shade window | Higher temperature, highly standardized | Nylon energy savings offset by chemical cost |
| Moisture management | Absorbs more, feels cooler | Wicks and dries faster | Polyester better for sweat-heavy, quick-dry programs |
| Stretch recovery | Superior — resists sagging | Moderate — can lose shape | Nylon lower cost per wear in swim and compression |
| Abrasion durability | Outlasts polyester in high friction | Wears faster under abrasion | Nylon lower cost per wear in activewear and uniform |
| Typical end-use | Swim, compression, high-abrasion activewear | Tees, casual knits, price-sensitive basics | Match fiber to garment life, not to unit price |
A practical way to read this table: if your garment’s expected life is long and the performance bar is high, nylon’s per-meter premium narrows or reverses on a cost-per-wear basis. If the garment is a short-life basic, polyester’s lower upfront cost and faster drying usually win. The mistake is applying a single fiber rule across an entire range.
Worked Example: Swim Brief
Take a 200 GSM swim brief in two constructions. A nylon-spandex knit holds shape through repeated chlorine exposure, so the garment stays in rotation for the full season. A polyester-spandex knit costs less upfront but loses recovery sooner, shortening the usable life and raising the effective cost per wear. The nylon premium is worth paying when the garment’s expected life is long and the performance bar is high — swim, compression, and high-abrasion activewear. It is not worth paying in everyday tees, casual knits, and price-sensitive basics, where polyester or cotton-poly blends deliver better margin at acceptable performance.
Compression and high-abrasion activewear follow the same logic. If the garment is worn against the skin, washed frequently, and expected to hold shape, nylon’s durability pays back over the garment’s life. For uniform and schoolwear, evaluate quick-dry and durability requirements against cost targets — if the program demands frequent washing and long wear cycles, nylon blends can reduce replacement frequency.
Blend ratios let you dial performance and cost simultaneously. A cotton-nylon blend can soften hand feel while adding durability; a polyester-nylon blend can balance cost and recovery. The key is to decide the performance floor first, then choose the cheapest fiber mix that clears it.

How to Reduce the Nylon Cost Penalty in Sourcing
Manage three cost layers — visible cost, risk cost, and efficiency cost — not just unit price. Risk cost from shade variation, lead-time failure, and compliance gaps can erase any fiber savings through rework and air freight. The penalty you are trying to reduce is the per-meter gap between nylon and polyester at the same weight — a structural premium on the fabric line, which is the number to negotiate against.
Start with GSM and construction. Lighter or differently knit structures reduce fiber consumption per garment. If your performance floor allows a lighter knit instead of a heavier one, you cut material cost without changing fiber. Work with your mill on stitch density and yarn count before you accept a weight increase.
Consolidate colors and plan MOQ to avoid small-batch surcharges. Every additional color adds dyeing setup, which is a fixed cost spread over fewer meters. If you can reduce your color count by one or two per season, the per-meter penalty drops. Plan MOQ around your mill’s minimum — for many factories, 500 kg per color and 2,000 kg per order is the threshold where pricing becomes efficient.
Lock fiber decisions early in development. Late-stage re-sampling and re-dyeing are pure risk cost. If you switch from polyester to nylon after lab dips are approved, you pay for new dyeing trials, new shade approvals, and potentially new testing. Decide the fiber before the first sample, not after the first fit session.
Finally, negotiate on total program value, not just unit price. A mill that runs its own knitting, dyeing, and finishing can control more of the cost stack and reduce the risk of third-party delays. That integrated model is often worth a small premium over a trading company that outsources every step.

FAQ
Is nylon fabric more expensive than polyester? Yes, nylon knit fabric is more expensive than polyester knit at the same weight and construction. The premium comes from raw material chemistry — nylon 6 derives from caprolactam, while polyester derives from PTA and MEG. Polyester offers lower cost and faster drying; nylon offers superior stretch recovery and durability.
How much more does nylon cost than polyester per meter? As a working reference, YXX quotation ranges for 180–220 GSM knits typically land around 9.00/kg for nylon 6 and 5.50/kg for polyester — a 40–60% premium that tracks the nylon 6 chip versus PET chip spread. The gap is driven by raw material, which accounts for 45–55% of total fabric cost in our programs. Because feedstock markets differ, the premium is structural rather than a supplier markup.
Why is nylon more expensive than polyester if both are synthetic? Both are synthetic, but they come from different upstream markets. Nylon 6 uses caprolactam; polyester uses PTA and MEG. Nylon knit capacity is also less commoditized, so fewer mills compete on the same construction. That reduces price pressure and keeps the premium sticky.
Is nylon worth the extra cost for activewear? For high-abrasion activewear, swim, and compression, yes — nylon’s superior stretch recovery and durability reduce returns and extend garment life, which can lower cost per wear below a cheaper polyester alternative. For short-life basics, polyester or cotton-poly blends usually deliver better margin.
Which is cheaper for t-shirts — nylon or polyester knit fabric? Polyester knit is cheaper for t-shirts, especially for price-sensitive basics and promotional programs. Nylon’s premium is hard to justify when the garment’s expected life is short and the performance bar is low. Cotton-poly blends are also a cost-effective middle ground for everyday tees.
