Gray Scale

Gray Scale
The Gray Scale is a visual tool used in the textile and dyeing industry to evaluate and grade the color change or staining of a fabric after testing (e.g., washing, rubbing, and light exposure). It helps assess how much a fabric’s color has altered or transferred during durability or fastness tests.
Types of Gray Scale:
- Gray Scale for Color Change – Compares the original and tested sample to measure color fading or alteration.
- Gray Scale for Staining – Compares a white adjacent fabric (before and after testing) to assess color transfer or staining.
Rating System :
– Uses a 1 to 5 scale:
– Grade 5: No change or staining (excellent)
– Grade 1: Severe change or heavy staining (poor)
Intermediate grades (like 4–5, 3–4, etc.) are also used for finer evaluation.
Construction :- Each scale includes pairs of gray chips with varying contrast levels to visually match the test results.
Usage Areas:- Textile testing labs- Dyeing and finishing quality control- Standards like ISO, AATCC, and BIS tests

- Cost-Effective Tool – Inexpensive yet essential for reliable quality control in textiles.
- Enhances Quality Assurance – Helps detect dyeing or printing issues before bulk production.
- Supports Multiple Tests – Used for evaluating wash fastness, rubbing fastness, perspiration, light exposure, and more.
- Portable and Durable – Easy to carry and long-lasting with proper care.
Features :
- Dual Type Availability – Comes in two types: for Color Change and for Staining.
- 5-Point Grading System – Grades from 1 (poor) to 5 (excellent), with half-step intervals like 4–5, 3–4.
- Standardized Grey Chips – Includes contrasting grey color pairs to match fabric changes accurately.
- Compact Design – Small, portable card or booklet format for easy lab and field use.
- Durable Material – Made from stable, fade-resistant plastic or cardboard for long-term use.
- Compliance with Standards – Follows ISO 105-A02 (Color Change) and ISO 105-A03 (Staining) norms.
- Easy Visual Comparison – Designed for quick side-by-side assessment of fabric before and after testing.
How to Use :
Select the Right Gray Scale – Use Color Change scale to check fading, or staining scale to check color transfer.
- Place the Samples – Lay the untested (original) and tested fabric side by side (for color change)
– Or place the adjacent white fabric next to the gray scale (for staining).
- Match Against Gray Scale Chips – Visually compare the difference between the samples and find the closest matching gray pair on the scale.
- Assign a Grade
– Grade from 1 to 5, where:
– Grade 5 = no change/staining
– Grade 1 = severe change/staining
– Use half-grades like 4–5 if needed.
- Record the Result – Note the grade in your test report as per the test method (e.g., ISO 105).
- Store Properly – Keep the gray scale away from light and moisture to avoid fading.

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. - Sample Size: Commonly 60 mm × 60 mm. - Test Cloth: Standardized white cotton cloth, either dry or wetted depending on the test condition.
