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
Benefits :
- Standardized Evaluation – Provides a consistent and objective way to assess color change or staining.

- 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.
- 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.

Categories:
- Gray Scale for Color Change – Used to evaluate the degree of color fading or change in a fabric after testing (e.g., washing, light exposure). – Assesses how much the original color has altered.
- Gray Scale for Staining – Used to assess the degree of color transfer from a dyed fabric to an adjacent white fabric during testing (e.g., rubbing, washing).
– Evaluates staining on undyed fabrics.
These two types are essential tools in color fastness testing across textile labs. Want to know which standard tests use each type?

Random Tumble Pilling Tester
Random Tumble Pilling Tester
The Random Tumble Pilling Tester is a specialized instrument designed to assess the pilling resistance of textile fabrics. Pilling refers to the formation of small, fuzzy balls (pills) on the fabric surface due to wear and friction. This tester simulates the wear conditions that fabrics experience during actual use, providing valuable data on their durability and appearance retention. Purpose of Random Tumble Pilling Tester The primary function of the Random Tumble Pilling Tester is to evaluate how fabrics resist pilling, fuzzing, and matting. This assessment is crucial for manufacturers aiming to ensure the longevity and aesthetic quality of their textile products. Working Principle of Random Tumble Pilling Tester The tester operates by placing fabric specimens into cylindrical test chambers lined with cork. Inside each chamber, a stainless steel impeller rotates at a high speed (typically around 1200 revolutions per minute), causing the fabric samples to tumble randomly. Compressed air is injected to enhance the tumbling action. This process simulates the friction and wear that fabrics undergo during regular use. After a predetermined duration, the samples are removed and visually assessed for pilling using standardized rating scales. Key Specifications of Random Tumble Pilling Tester Test Chambers: Available in configurations of 2 or 4 chambers to accommodate multiple samples simultaneously. - Rotation Speed: Approximately 1200 revolutions per minute. - Chamber Dimensions: Typically around 146 mm in diameter and 152 mm in length. - Impeller Size: Standard impellers measuring about 121 mm. - Compressed Air Pressure: Adjustable, commonly between 14–21 kPa (2–3 psi). - Timer: Digital timer allowing precise control over test duration. - Power Supply: Generally operates on 220V, 50Hz power sources. Applicable Standards of Random Tumble Pilling Tester The Random Tumble Pilling Tester complies with several international testing standards, ensuring its suitability for global applications:- ASTM D3512- ISO 12945-3- DIN 53867- JIS L 1076- GB/T 4802.4 Benefits of Random Tumble Pilling Tester - Realistic Simulation: Accurately replicates the wear and friction conditions fabrics face during actual use.- Standardized Testing: Adheres to international standards, facilitating consistent and comparable results.- Efficient Evaluation: Allows simultaneous testing of multiple samples, increasing laboratory throughput.- Quality Assurance: Provides manufacturers with critical data to improve fabric formulations and production processes.
