TQC sheen – Abrasion Testers – Taber Crockmeter

The Taber® Crockmeter 418 provides a quick and accurate method to determine the amount of color that is transferred by rubbing textile materials to other surfaces. The Taber Crockmeter was originally designed to simulate the action of a human finger and forearm, as described in internationally recognized test standards. The Taber® Crockmeter uses a standard pressure and rubbing motion to provide reliable and reproducible test results. The Taber® Crockmeter has been used to test most colored textiles including fabric, carpeting, yarn and leather. The Taber® Crockmeter can also be used to perform smudge and smear resistance tests on printed or copied images, along with rub abrasion, scuff and / or mar tests on flat painted specimens.

Originally designed to simulate the action of a human finger and forearm, the Crockmeter uses a standard pressure and rubbing motion to provide reliable and reproducible test results. Specimens are positioned on the base of the Crockmeter and held in place with the sample holder. To prevent the specimen from shifting during testing, a sandpaper pad is provided to place under the specimen. A hand crank moves a reciprocating arm a distance of approximately 100mm. The rubbing action is provided by a 16mm diameter acrylic ‘finger’ which moves back and forth in a straight line with each complete turn of the crank. The reciprocating load arm is weighted to provide a constant 9N load on the sample at all times and a mechanical counter keeps track of completed cycles.
