Frequently asked questions

What is the most common textile test?

Colorfastness to washing (ISO 105-C06 / AATCC TM 61). Most-frequently-run because every garment that goes through laundry must not bleed.

What is the difference between AATCC and ISO?

AATCC is the American standard (TM 61, 8, 16, 135). ISO is the international standard. Most tests have equivalent versions; labs run whichever the buyer specifies.

How long does textile testing take?

Standard tests take 1-5 days. Colorfastness to light (ISO 105-B02) is the longest at 20-80 hours of xenon-arc exposure. A 10-15 test suite takes 5-10 business days.

What is a 1-5 gray scale for colorfastness?

A visual rating: 5 = no change, 4 = slight, 3 = noticeable, 2 = considerable, 1 = severe. Used in ISO 105 and AATCC TM. Commercial-grade fabric rates 4+ dry and wet.

What is the difference between Martindale and Wyzenbeek?

Both test abrasion. Martindale (ISO 12947) uses circular rubbing; Wyzenbeek (ASTM D4157) uses linear back-and-forth. Wyzenbeek results are roughly double Martindale for the same fabric. US uses Wyzenbeek; EU uses Martindale.
