Digital Crockmeter for Colour Fastness to Rubbing Testing
A Digital Crockmeter is a testing instrument used to evaluate a fabric’s colour fastness to rubbing — how well dye stays put when the material is repeatedly rubbed against another surface, wet or dry. Amith Garment Services offers this crockmeter for testing woven, knitted, and non-woven fabrics, as well as yarns and finished garments, in line with both ISO and AATCC test methods.
The unit uses an electric motor to drive automatic, standardized rotations, removing the inconsistency of manual crocking and giving labs repeatable results. Chrome-plated mild steel components support long-term, trouble-free use, while interchangeable finger attachments (16mm for apparel fabrics, 25mm for furnishings) accommodate different fabric categories. An optional 22N dead weight attachment and yarn-testing fixture extend its versatility for specialized rub-fastness assessments.
Textile mills, apparel export houses, dye houses, and garment quality control labs use crockmeters to confirm colour fastness before shipment, helping meet buyer compliance requirements tied to standards like ISO 105-X12, AATCC 8/165, and ASTM F1319.
Amith Garment Services has supplied Indian textile testing labs since 1999, backing every crockmeter with an NPL/NABL-traceable calibration certificate, warranty, and detailed user manual.

Frequently Asked Questions:
What is a Crockmeter used for in textile testing?
A Crockmeter is used to measure colour fastness to rubbing by checking whether dye transfers from a fabric onto another surface during dry or wet rubbing. It is an essential quality control instrument for apparel, home textiles, yarns, and fabrics before production or export.
Which standards does the Digital Crockmeter comply with?
The Digital Crockmeter from Amith Garment Services complies with major international testing standards, including ISO 105-X12, AATCC 8, AATCC 165, BS 1006 D02, JIS L 0849, and ASTM F1319. This makes it suitable for laboratories serving both domestic and international textile markets.
What is the difference between manual and digital Crockmeters?
A digital or motorized Crockmeter performs rubbing cycles automatically using an electric motor, ensuring consistent speed and pressure throughout the test. This improves repeatability, reduces operator error, and delivers more reliable results than manually operated Crockmeters.
What is a Crockmeter?
A Crockmeter is a textile testing instrument used to determine a fabric's colour fastness to rubbing. It evaluates whether colour transfers from the test fabric to a standard white cloth during controlled friction, helping manufacturers verify product quality.
How does a Digital Crockmeter work?
A Digital Crockmeter rubs a standard white test cloth against the fabric sample using motor-driven movements under controlled pressure. The amount of colour transferred is then compared with a grey scale to determine the fabric's rubbing fastness rating according to international standards.
