Moisture-Wicking Fabric: B2B Sourcing Guide & AATCC Testing
Direct Answer
Moisture-wicking fabric uses capillary action to transport sweat from the skin surface to the outer fabric layer where it evaporates. Unlike cotton, which absorbs moisture INTO the fiber (becoming heavy and slow-drying), polyester and nylon move moisture ALONG fiber surfaces—drying in 2-3 hours vs. cotton's 6-8+ hours.
For B2B sourcing, the key specifications are:
- AATCC 195 grade — Industry-standard moisture management test. Grade 4-5 = excellent wicking; Grade 3 = acceptable minimum for activewear
- Fiber type — Polyester and nylon are hydrophobic (moisture regain <0.4%); cotton is hydrophilic (absorbs 25x its weight)
- Fabric construction — Mesh and textured knits wick better than dense, tight constructions
- Surface treatment — Hydrophilic finishes enhance wicking but may wash out after 20-50 cycles
Wicking performance hierarchy:
- Best: Mesh fabrics, lightweight textured knits (100-150gsm)
- Very good: Standard polyester jersey, pique (150-200gsm)
- Good: Medium-weight knits (200-250gsm)
- Poor: Dense tight knits, cotton, blends with >35% cotton
TL;DR — Key Sourcing Takeaways
- Wicking ≠ absorption: Polyester moves moisture along surface (dries fast); cotton absorbs into fiber (stays wet)
- Request AATCC 195 testing: Only objective way to compare moisture management—don't accept "moisture-wicking" marketing without data
- Fiber matters most: All polyester wicks inherently; modified cross-section fibers (channel, tri-lobal) enhance performance
- Fabric weight affects drying: 100-150gsm dries in 2-3 hours; 250gsm+ takes 4-5 hours
- Avoid fabric softeners: They coat fibers and reduce wicking performance—communicate this in care labels

Why Moisture-Wicking Matters for Activewear
Moisture management is the foundation of athletic apparel performance. Get it wrong, and every other feature fails.
The sweating problem: During exercise, the body produces 0.5-2 liters of sweat per hour. This moisture must leave the skin-fabric interface or the athlete experiences:
- Clammy, uncomfortable sensation
- Increased chafing and skin irritation
- Overheating (wet fabric loses thermal regulation)
- Perceived heaviness (cotton can absorb 25x its weight)
How wicking solves it: Hydrophobic fibers (polyester, nylon) don't absorb moisture—they transport it via capillary action. Sweat moves from the warm skin side to the cooler outer surface, spreads across a large area, and evaporates rapidly.
Why this matters for B2B:
- Customer complaints about "fabric stays wet" drive returns
- Athletes choose brands based on comfort during performance
- Proper wicking creates competitive differentiation
- AATCC-tested fabrics justify premium pricing
The Science: How Wicking Works (5 Steps)
Step 1: Sweat Contacts Fabric
Moisture from skin reaches the fabric's inner surface through direct contact. Athletic fit matters—loose garments have limited skin contact, reducing wicking efficiency.
Step 2: Capillary Action Initiates Transport
The hydrophobic nature of polyester creates surface tension differences. Moisture moves along the fiber surface (not into it) through capillary action in the yarn and fabric structure.
Step 3: Moisture Spreads Across Surface Area
Fabric construction creates pathways for lateral spreading. Open knit structures, mesh, and textured surfaces increase spreading area, accelerating evaporation.
Step 4: Evaporation at Outer Surface
With moisture spread across a large area on the fabric's outer surface, evaporation occurs rapidly. Lighter fabrics evaporate faster due to less mass and more surface-area-to-weight ratio.
Step 5: Vapor Escapes to Atmosphere
The final step requires breathability—fabric porosity that allows water vapor to pass through. Dense, tight constructions can wick but trap vapor.
AATCC 195 Testing Specification Guide
Understanding the Test
AATCC Test Method 195 (Liquid Moisture Management Properties of Textile Fabrics) is the industry standard for objective moisture management measurement.
What AATCC 195 Measures:
| Metric | What It Means | Why It Matters |
|---|---|---|
| Wetting Time (Top) | Time for moisture to spread on inner surface | Faster = moisture moves away from skin quickly |
| Wetting Time (Bottom) | Time for moisture to reach outer surface | Faster = quicker transport to evaporation zone |
| Absorption Rate | Speed of moisture uptake | Higher = fabric accepts moisture readily |
| Max Wetted Radius | How far moisture spreads | Larger = more surface area for evaporation |
| Spreading Speed | Rate of radial expansion | Faster = quicker distribution |
| One-Way Transport | Net moisture movement skin→outer | Higher = better moisture removal from skin |
| Overall MMT Grade | Composite performance score | Grade 4-5 = excellent |
Grading Scale
| Grade | Performance | Application Suitability |
|---|---|---|
| 5 | Excellent | Premium performance wear, competition apparel |
| 4 | Very Good | Quality activewear, training gear |
| 3 | Good | Acceptable for casual activewear |
| 2 | Fair | Not recommended for performance use |
| 1 | Poor | Not suitable for athletic applications |
Specification Requirements by Application
| Application | Minimum Grade | Recommended Grade |
|---|---|---|
| Competition running/cycling | 4 | 5 |
| Training/gym wear | 3 | 4 |
| Team jerseys | 3 | 4 |
| Casual activewear | 2 | 3 |
| Athleisure/lifestyle | 2 | 3 |

Common Wicking Fabric Mistakes
Mistake 1: Accepting "Moisture-Wicking" Marketing Without Data
The problem: Every polyester fabric claims moisture-wicking because polyester is inherently hydrophobic. But performance varies significantly. The fix: Request AATCC 195 test reports. Compare one-way transport index (OMMC) and overall grade across fabrics.
Mistake 2: Specifying Cotton Blends for Performance Wear
The problem: 50/50 or 65/35 cotton-poly blends wick worse than 100% polyester. Cotton absorbs and holds moisture. The fix: Use 100% polyester or 95/5 poly-spandex for performance applications. Reserve cotton for lifestyle/athleisure where performance is secondary.
Mistake 3: Ignoring Fabric Weight Impact on Drying
The problem: Heavy fabrics (250gsm+) take 2x longer to dry than lightweight (150gsm), even with identical wicking properties. The fix: Specify lighter weights (100-180gsm) for high-intensity summer applications; accept 180-220gsm for year-round training.
Mistake 4: Using Dense Tight Knits for Maximum Wicking
The problem: Dense constructions move moisture but trap vapor. Wicking without breathability leaves moisture at the surface. The fix: Balance wicking with breathability. Mesh panels, open knit structures, and textured surfaces enable both.
Mistake 5: Not Communicating Care Instructions
The problem: Customers use fabric softener, which coats fibers and ruins wicking performance. They blame the product. The fix: Include clear care labels: "Avoid fabric softeners to maintain moisture-wicking performance."
Mistake 6: Confusing Wicking with Quick-Dry
The problem: All polyester is hydrophobic, so technically all polyester wicks. But drying speed depends on weight, construction, and breathability. The fix: Specify both wicking (AATCC 195) and drying time in your requirements. They're related but not identical.
