Fastness Rotary Friction Tester
Fastness Rotary Friction Tester
A Fastness Rotary Friction Tester, also known as a Rotary Crock meter, is a specialized instrument used to evaluate the color fastness of textiles and materials when subjected to rotational rubbing. This test simulates the wear and friction that fabrics experience during use, helping manufacturers assess the durability of dyes and finishes.
Purpose of Fastness Rotary Friction Tester
The primary function of the Fastness Rotary Friction Tester is to determine how well a fabric’s color withstands rubbing, both in dry and wet conditions. This is crucial for ensuring the longevity and appearance of textiles in real-world applications, such as clothing, upholstery, and footwear.
Working Principle of Fastness Rotary Friction Tester
The tester operates by applying a specified pressure to a fabric sample using a standardized rubbing finger covered with a test cloth. The rubbing finger performs a set number of rotational movements (typically 1.125 turns clockwise followed by 1.125 turns counterclockwise) over the fabric surface. After the test, the degree of color transfer to the test cloth and any changes in the fabric’s appearance are evaluated against standardized gray scales.
Common Testing Standards
– AATCC 116: Colorfastness to Crocking: Rotary Vertical Crock meter Method.
ISO 105 X16: Textiles—Tests for color fastness—Part X16: Color fastness to rubbing—small areas.
– SATRA TM8: Color fastness to rubbing.
Key Specifications of Fastness Rotary Friction Tester
– Rubbing Head Diameter: Typically 16 mm.
– Applied Pressure: Approximately 1134 grams (11.1 N).
– Rotation: 1.125 turns clockwise followed by 1.125 turns counterclockwise.
