The Rotary Rubbing Color Fastness Tester, also known as a Crockmeter, is widely used in the textile industry to evaluate the color fastness of fabrics under dry and wet rubbing conditions. It is particularly suitable for printed fabrics and provides precise, reproducible results according to international textile standards. The instrument simulates real-world abrasion to assess fabric performance during wear, laundering, or handling.

Application

The tester is mainly used for printed fabrics and dyed textiles to determine resistance to color transfer caused by friction. Key applications include textile printing, garment manufacturing, quality control, and R&D in fabric finishing and dyeing.

Standards

ISO 105-X12 (Textiles — Color fastness — Tests for color fastness to rubbing)
AATCC 8 (Colorfastness to Crocking)

Features

(1) High-precision friction head with 16mm diameter delivering 1143g pressure.
(2) Friction rotation sequence: 1.125 cycles clockwise followed by counterclockwise rotation for uniform testing.
(3) One-way rotation handle ensures consistent operation.
(4) Steel spring sample holder allows rapid specimen fastening and reproducible results.
(5) Designed to comply with AATCC and ISO standards for textile color fastness testing.
(6) Suitable for testing both dry and wet rubbing resistance.
