What Is AATCC Testing for Performance Fabrics?

AATCC test methods are the quality language of the textile industry. Knowing the key tests helps you verify fabric performance — and avoid paying for claims that were never tested.

AATCC (American Association of Textile Chemists and Colorists) develops the standard test methods used to verify textile quality worldwide. Understanding AATCC testing lets you evaluate fabric performance objectively. Mibein Textile conducts full AATCC and lab testing on all performance fabric programs.

What Is AATCC?

The American Association of Textile Chemists and Colorists (AATCC) develops voluntary standards for evaluating textiles — covering colorfastness, shrinkage, physical properties, and performance. AATCC test methods are referenced globally by brands, labs, and suppliers. When a spec sheet says “colorfastness 4-5,” that rating only means something if you know which AATCC method produced it. This guide decodes the methods that matter most for performance fabrics.

Why Testing Matters for Buyers

Test reports are the evidence behind every performance claim — without them, “moisture-wicking” or “colorfast” is just marketing. For brands, AATCC testing protects against: garments that fade in the first wash, shrinkage that ruins fit, pilling that cheapens the look, and performance claims that fail in the field. Requesting and understanding test reports is the difference between sourcing blind and sourcing with confidence.

Colorfastness Tests

Colorfastness measures resistance to fading or transfer. Key methods: AATCC 61 (colorfastness to laundering), AATCC 8 (crocking/rubbing — color transfer to other surfaces), AATCC 15 (perspiration), AATCC 16 (light). Ratings run 1-5 (or 1-8 for light), with 4-5 considered good for most apparel. For performance and sportswear, laundering and perspiration fastness are critical — garments face sweat and frequent washing.

Shrinkage Testing

Shrinkage testing (AATCC 135 for dimensional change) measures how a fabric changes after laundering. The sample is washed and dried under controlled conditions, and the change in dimensions is recorded as a percentage. For knits, acceptable shrinkage is typically under 3-5% in both directions. High shrinkage produces garments that don’t fit after washing — a leading cause of returns. Check shrinkage on the finished, garment-ready fabric, not the greige.

Pilling and Abrasion

Pilling — those little balls of fiber on the surface — degrades a garment’s look quickly. AATCC 127 (Martindale) or AATCC 124 test resistance to pilling by abrading the fabric and rating surface change on a 1-5 scale (5 = no change). For activewear, which faces constant friction, pilling resistance of 4+ is the quality bar. Abrasion resistance (cycles before wear-through) is also tested for durability-critical products.

Moisture Management Tests

For performance fabrics, moisture management is measured with AATCC 195 (liquid moisture management properties). This test measures how quickly a fabric wicks moisture, its one-way transport, and drying characteristics — producing a detailed performance profile rather than a single number. Other relevant methods: ASTM D737 (air permeability) and AATCC 22 (water repellency spray test). These tests turn “moisture-wicking” into measurable data.

Key AATCC Methods Table

Method	What It Tests	Good Result
AATCC 61	Colorfastness to laundering	4-5 (excellent)
AATCC 8	Crocking (color transfer)	4+ dry, 3+ wet
AATCC 15	Colorfastness to perspiration	4+
AATCC 16	Colorfastness to light	4+ (fade resistance)
AATCC 135	Dimensional change (shrinkage)	<3-5%
AATCC 124	Appearance after laundering	4+ (no pilling)
AATCC 195	Liquid moisture management	Good-excellent profile

How to Verify Test Claims

Always request test reports for your specific fabric and color — not generic marketing claims. Verify: the report covers your color (dye lots differ), the test lab is accredited (ISO 17025), and results meet your required thresholds. For high-stakes claims (moisture-wicking, UPF, colorfastness), commission independent third-party testing on production samples. Mibein provides test reports and factory inspection for all programs.

FAQ

What does AATCC stand for?

AATCC is the American Association of Textile Chemists and Colorists — the organization that develops standard test methods for textile quality and performance.

What AATCC tests should I request for sportswear?

Prioritize: AATCC 61 (laundering fastness), AATCC 135 (shrinkage), AATCC 124 (appearance/pilling), and AATCC 195 (moisture management) for performance fabrics.

What is a good colorfastness rating?

For most apparel, a rating of 4-5 on laundering and perspiration fastness is considered good to excellent. Below 3.5, fading or transfer is likely to be visible.

How do I know if a supplier’s test report is reliable?

Verify the lab is ISO 17025 accredited, the report covers your exact fabric and color, and results were produced recently. Prefer independent third-party testing for critical claims.
