Motorized Rubbing Colorfastness Tester

The Motorized Rubbing Colorfastness Tester is designed for evaluating the dry and wet rubbing colorfastness of textiles, knits, and leather. The instrument uses a friction head fitted with a standard white cloth to perform reciprocating motion over the specimen, simulating wear and color transfer. The color transfer on the white cloth is assessed using gray scales, providing reliable data for material evaluation and selection. The fully motorized design ensures consistent results, higher efficiency, and repeatability compared to manual methods.

Application

This tester is suitable for:

(1) Determining dry and wet rubbing colorfastness of cotton, wool, linen, silk, and knitted fabrics;

(2) Assessing printed textiles and surface coatings for color stability;

(3) Textile production quality control and R&D laboratories;

(4) Leather and synthetic materials testing for color transfer resistance.

Standards

The instrument complies with the following international and national standards:

(1) ASTM F1319 – Standard Test Method for Colorfastness to Crocking;

(2) AATCC 8 / 165 – Colorfastness to Crocking;

(3) BS 1006 D02 – British Standard for colorfastness to rubbing;

FAQ

What is this product?

A motorized instrument for measuring the dry and wet rubbing colorfastness of textiles, knits, leather, and coated materials.

What is the purpose of this product?

To evaluate the degree of color transfer from a sample to a standard white cloth under controlled friction conditions.

Why is this product important?

It ensures consistent, reproducible results, helps maintain quality standards, and prevents unwanted color transfer in end products.

What problems can this product solve for users?

Detects poor rubbing resistance, evaluates material durability, and provides objective data for quality control and R&D.

What types of this product are available?

Motorized versions with 16 mm or 25 mm friction heads, capable of dry and wet rubbing tests.

How is this product operated?

(1) Condition specimens and standard white cloths in a controlled environment;

(2) Mount specimens and attach the white cloth to the friction head;

(3) Set test cycles and start the motorized test;

(4) For wet tests, pre-moisten the white cloth and repeat;

(5) Assess color transfer using gray scales and record results for dry and wet tests separately.
