The Complete Guide to Tricot Knit Nylon Fabric: Properties, Uses, and Sourcing

When you see the term “tricot nylon fabric,” it describes a very specific and widely used construction within the world of synthetics. It’s not just any nylon; it’s nylon that has been knitted using the tricot warp knitting technique. This combination creates a fabric with a unique set of characteristics that make it a powerhouse in activewear, swimwear, intimates, and outdoor gear. Understanding this fabric means separating the properties of the base fiber (nylon) from the structure created by the tricot knit.

This guide will break down exactly what makes tricot-knit nylon distinct, where it excels (and where it doesn’t), how to source it intelligently, and what to consider for care and sustainability. Whether you’re a designer, a small brand owner, or an informed consumer, knowing these details helps you make better material choices.

What Is Tricot Knit Nylon? Decoding the Terminology

The name is a two-part descriptor:

• Nylon: The synthetic polymer fiber, first introduced by DuPont in the 1930s. It’s known for high strength, elasticity, abrasion resistance, and quick-drying properties. Common types in apparel are Nylon 6 and Nylon 6,6.
• Tricot: A specific warp knitting construction. Unlike weft knitting (like a hand-knit sweater where one yarn forms a row), warp knitting uses multiple yarns that run lengthwise (warp-wise) and are interlooped by a machine. A tricot machine has two sets of warp yarns: one set of “ground” yarns and one set of “plating” or “inlay” yarns that lay on top. This creates a fabric with a smooth, often slightly ribbed front surface and a more textured back, with the yarns running diagonally.

The result is a fabric that is inherently run-resistant (a critical feature for hosiery and swimwear), dimensionally stable, and has excellent drape. It’s the primary reason your swimsuit or cycling shorts hold their shape under stress.

Key Properties of Tricot-Knit Nylon: A Technical Breakdown

The magic is in the synergy between the fiber and the knit structure. Here’s a practical breakdown of what you can expect.

Tradeoff Alert: The tight, stable structure of tricot knit can sometimes feel less “soft” or “breathable” than a more open jersey knit, even with the same fiber. However, for performance, its stability is non-negotiable.

Performance Profile Deep Dive

• Moisture Management: Nylon itself is hydrophobic (water-hating). It doesn’t absorb moisture but can wick it across its surface to the outer layer for evaporation. Tricot’s smooth surface aids this. It will feel clammy if saturated, but dries quickly.
• Thermal Properties: It’s not inherently warm. Its insulation comes from trapping air in its structure. Lightweight tricot is for warm-weather or high-exertion use. Heavier, brushed tricot (like in fleece) can provide warmth.
• Durability Limits: While abrasion-resistant, nylon is susceptible to UV degradation (it weakens and yellows in sunlight). It also melts under high heat (ironing or dryers). Chlorine (from pools) can degrade it over time, though tricot knits for swimwear are engineered for better chlorine resistance.
• Pilling: Lower-quality nylon or loosely constructed tricot can pill. Look for fabrics with a high denier (thicker yarn) or with treatments like mercerization or silicone finishes to reduce this.

Primary Applications: Where Tricot-Knit Nylon Dominates

You find this fabric where shape and recovery are paramount.

• Swimwear & Activewear: The undisputed king. Its run-resistance prevents catastrophic tears, and its compression/containment properties are essential for performance swimsuits, cycling shorts, yoga pants, and base layers. Brands like Speedo and Under Armour rely on specialized tricot knits.
• Hosiery & Intimates: From ultra-sheer pantyhose to supportive shapewear, tricot’s smoothness and run-proof nature are essential. It provides the necessary compression and smooth silhouette.
• Outdoor & Utility: Used in windshells, softshell jackets (often as a face fabric bonded to a membrane), and backpacks for its smooth, abrasion-resistant surface and wind-blocking ability.
• Lining & Technical Garments: Its low friction makes it ideal for jacket linings (reduces snagging on underlying layers) and as a stable substrate for bonding performance membranes (like Gore-Tex).

Sourcing Tricot Nylon Fabric: A Practical Guide for Buyers

Sourcing this fabric requires understanding a few key specs beyond just “nylon.”

Critical Questions to Ask Suppliers

Use this checklist when evaluating samples or quotes:

1. What is the nylon type and denier per filament (DPF)? Nylon 6,6 is generally stronger and more heat-resistant than Nylon 6. Lower DPF (e.g., 15D) creates a softer, silkier hand; higher DPF (e.g., 70D) creates a tougher, more opaque fabric.
2. What is the fabric weight (gsm or oz/yd²)? Light: 80-120 gsm (lining, sheer hosiery). Medium: 130-200 gsm (swimwear, activewear). Heavy: 210+ gsm (wind shells, heavy-duty utility).
3. What is the stretch percentage and recovery? Stretch is usually in the width (cross-grain). 10-20% is common for swim, 20-30%+ for activewear. Recovery must be 90%+ for performance applications. Request a stretch test report.
4. Is it brushed or unbrushed? Brushing (raising the nap) creates a softer, warmer hand and better opacity (used in fleece). Unbrushed is smoother and more transparent.
5. What finishes are applied? Common ones include:
   • DWR (Durable Water Repellent): For water-shedding.
   • Chlorine Guard/C&X: For swimwear to resist pool chemicals.
   • Anti-Pilling: Surface treatments.
   • UV Protection: Additives that block UV rays.
6. Where is it manufactured and to what standards? Look for OEKO-TEX Standard 100 (chemical safety) or bluesign® (environmental & toxicology) certifications, especially for next-to-skin applications. For military or industrial use, specifications like MIL-DTL-XXXX may apply.

Navigating Wholesale and Minimums

Tricot knitting machines are capital-intensive. This leads to:

• Higher Minimum Order Quantities (MOQs): Often 1,000-5,000 yards for custom construction from mills. Stock fabrics from distributors may have lower minimums (e.g., 10-50 yards).
• Lead Times: Custom warp-knit fabrics have longer lead times (8-16 weeks) than weft-knit jerseys due to machine setup and yarn warping.
• Supplier Types: You’ll work with textile converters (who stock and finish fabrics) or direct fabric mills (who produce the greige goods). For small batches, a converter or distributor like Fabric.com (for basics) or a specialty technical fabric supplier is the starting point. For larger, custom runs, sourcing agents or direct mill relationships are necessary.

Cost Driver: The primary cost is not the nylon yarn itself, but the machine time and warp preparation. Complex patterns (like intricate mesh or variegated plating) add significant cost.

Care, Longevity, and Environmental Considerations

Proper care maximizes the life of tricot nylon garments.

• Washing: Use cool or warm water. Avoid hot water, which can set wrinkles and accelerate degradation. Use mild detergents; bleach (especially chlorine) will severely damage nylon fibers.
• Drying: Air dry is strongly recommended. High heat in dryers can melt the fibers, cause irreversible shrinkage, and destroy elasticity. If you must tumble dry, use the lowest heat setting.
• Ironing: Use a cool iron with a press cloth. High heat will melt or shine the fabric.

Environmental Footprint: Nylon is a petroleum-based polymer. Its production is energy and chemical intensive. However, options are improving:

• Recycled Nylon (e.g., ECONYL®): Made from pre- and post-consumer waste (fishing nets, carpet fluff). Performance is nearly identical to virgin nylon. ECONYL® is a leading brand.
• Bio-based Nylon: Partially derived from renewable resources like castor oil (e.g., BASF’s Ultramid® BS).
• End-of-Life: Nylon is recyclable, but infrastructure for apparel recycling is limited. Seek out brands with take-back programs.

Making the Decision: Is Tricot-Knit Nylon Right For You?

Ask these final questions:

• Is run-resistance and shape-holding critical? If yes, tricot is likely your best knit choice. For a simple, stretchy t-shirt, jersey is cheaper and softer.
• What is the primary stress? Abrasion from backpacks? Chlorine from pools? UV from sailing? Match the fabric’s specific treatment and denier to the stress.
• What is your budget and volume? For prototypes or small runs, stock tricot fabrics from distributors are the only viable path. For full-scale production, be prepared for mill MOQs and lead times.
• Can you commit to proper care instructions? If your customer base will machine-dry on high heat, the garment’s lifespan will be drastically shortened, negating any durability benefits.

Frequently Considered Questions

How can I tell if a fabric is tricot knit? Look at the reverse side. A tricot knit will show a distinct pattern of diagonal floats (the inlay yarns) crossing over the vertical columns of the base knit. It won’t look like the neat rows of a jersey knit. You can also gently tug a yarn; in tricot, it’s harder to pull a single yarn through the fabric due to the warp structure.

Is tricot always nylon? Can it be polyester? No. “Tricot” refers to the knit structure. You can have tricot-knit polyester, tricot-knit cotton (rare), or tricot-knit blends. However, in performance apparel, “tricot” almost always implies nylon or a nylon/spandex blend due to nylon’s superior strength and recovery.

What’s the difference between tricot and mesh? Tricot can be made into a mesh by using large, open yarns and specific machine gauges. But not all tricot is mesh, and not all mesh is tricot (some mesh is produced via warp knitting with different structures like Raschel). Mesh tricot focuses on breathability, while solid tricot focuses on containment and smoothness.

Is recycled nylon tricot as durable as virgin? High-quality recycled nylons like ECONYL® meet or exceed the performance specifications of virgin nylon 6,6 in tensile strength and pilling resistance. The key is ensuring the recyclate is from a pure source and processed correctly by a reputable mill.
