Color fastness testing is especially important when materials are exposed to rubbing, washing, moisture, perspiration, dry cleaning, light, or repeated contact with other surfaces. A textile lab may need to evaluate dry and wet crocking, washing fastness, staining of adjacent fabrics, shade change, dye bleeding, finish stability, and appearance change after exposure. Reliable testing helps reduce product complaints, improve supplier approval, and support quality control decisions before materials move into production.
NextGen Material Testing helps laboratories choose color fastness testing equipment based on the material, test method, standard, sample type, and workflow requirement. Whether you are evaluating dyed fabrics, printed textiles, garments, footwear linings, coated materials, leather surfaces, or finished products, the right testing system helps improve repeatability, document performance, and support compliance with recognized test methods.
Color Fastness Testing Equipment for Textile Quality Control
Color is one of the first quality characteristics a customer notices, but it can also be one of the most difficult to control. Dyes, pigments, prints, coatings, finishes, and fabric blends can all respond differently to rubbing, laundering, moisture, heat, and repeated contact. Color fastness testing helps identify these risks before they affect finished products, production batches, or customer satisfaction.
For quality control teams, color fastness testing equipment supports incoming material inspection, supplier comparison, product development, production verification, and failure analysis. Instead of relying only on visual checks, laboratories can use controlled testing to compare color transfer, staining, fading, washing behavior, and appearance change under repeatable conditions.
The best equipment choice depends on the material, the color fastness risk being evaluated, and the required test method. A dyed fabric may need washing fastness testing, while a printed textile, leather surface, or lining material may require rubbing or crocking evaluation under dry and wet contact conditions. Matching the equipment to the method helps ensure that results are meaningful, repeatable, and useful for quality decisions.
What Color Fastness Testing Evaluates
Color fastness testing focuses on how well a material keeps its original color and how much color transfers to other surfaces during use or care. The exact evaluation depends on the test method, material type, exposure condition, and final product application.
| Color fastness Risk |
What It Means |
Why It Matters |
| Color Transfer |
Dye, pigment, or finish transfers from the test specimen to another surface during rubbing or contact |
Helps reduce staining on skin, linings, other garments, furniture, footwear components, or adjacent materials |
| Fading |
The original shade becomes lighter or visibly changed after exposure, use, or care |
Helps maintain product appearance, brand consistency, and customer expectations over time |
| Staining |
Adjacent fabrics, linings, or test materials become stained during washing, rubbing, or wet exposure |
Helps evaluate dye bleeding, cross-staining, and contamination risk in finished products |
| Shade Change |
The color shifts after laundering, rubbing, moisture exposure, or service conditions |
Helps compare batches, suppliers, dye lots, finishing processes, and care performance |
| Finish Wear |
A surface coating, print, treatment, or finish changes after repeated contact or care |
Important for printed fabrics, coated textiles, leather surfaces, footwear materials, and finished goods |
Color Transfer and Crocking
Color transfer testing helps determine whether dye or finish moves from a material to another surface during dry or wet rubbing. This is important for dyed fabrics, printed materials, footwear linings, leather surfaces, upholstery, and products that come into direct contact with skin, clothing, or adjacent components.
Fading, Staining, and Shade Change
Fading and staining evaluations help laboratories understand how materials respond to laundering, moisture, contact, and care conditions. These tests can reveal whether a material loses color, bleeds into adjacent fabrics, or changes appearance after exposure. Consistent evaluation supports better material selection, supplier approval, and production quality control.
Common Color Fastness Test Methods
Color fastness testing methods are selected according to the material, product type, exposure condition, and performance requirement. Some tests focus on rubbing or crocking, while others evaluate washing fastness, staining, shade change, dry-cleaning performance, or appearance retention after controlled care conditions.

Rubbing and Crocking Fastness Testing
Rubbing and crocking fastness testing is used to evaluate whether color transfers from a textile, leather surface, or finished material to a rubbing cloth under controlled dry or wet contact conditions. NextGen’s GenCrock Pro Electronic Crockmeter is designed for color fastness testing under dry and wet rubbing conditions with controlled pressure and fixed stroke geometry.
Washing and Laundering Fastness Testing
Washing fastness testing helps laboratories evaluate color change, staining, dye bleeding, and appearance retention after controlled laundering or dry-cleaning style exposure. NextGen’s GenWashLab Color Fastness to Washing Tester is built for controlled wash fastness evaluation of dyed textiles.
Staining, Shade Change, and Appearance Evaluation
Many color fastness tests involve evaluating both the original specimen and adjacent materials after exposure. Labs may compare shade change, staining, transfer, or finish wear using visual assessment tools, grey scale ratings, or customer-specific reporting procedures. These evaluations help quality teams determine whether a material is suitable for production, care labeling, or final product use.
Water, Perspiration, Light, and Service Exposure Conditions
Some color fastness programs may also evaluate how materials respond to moisture, perspiration, light exposure, or other service conditions. The required method depends on the product, market, material construction, and customer requirements. When these conditions are part of a test program, the equipment and procedure should be selected to match the applicable standard or internal specification.
Materials and Products That Require Color Fastness Testing
Color fastness testing can be used across many textile and material categories. The test method should be selected based on the material structure, dye or finish system, end-use conditions, and the type of color risk being evaluated.

Dyed and Printed Fabric Testing
Dyed and printed fabrics are commonly tested for color transfer, shade change, staining, and washing performance. These results help manufacturers compare dye lots, printing processes, finishing treatments, and supplier materials before the fabric is cut, sewn, or released for production.
Garments, Linings, and Finished Goods
Finished products can create color issues that are not always visible at the material stage. A lining may stain an outer fabric, a dark garment may bleed during washing, or a printed surface may transfer color during contact. Testing finished goods helps quality teams evaluate performance in a form closer to real use.
Leather, Coated Materials, and Footwear Components
Leather, synthetic leather, coated fabrics, and footwear materials may require color fastness testing when surface finishes, coatings, dyes, or pigments are exposed to rubbing, moisture, or repeated contact. These tests help evaluate whether the surface remains stable and whether color transfer could affect adjacent materials or the end user.
Choosing the Right Color Fastness Testing Equipment
Selecting the right color fastness testing equipment starts with defining the material, color risk, exposure condition, and required test method. A dry crocking test, a wet rubbing test, a wash fastness test, and a dry-cleaning evaluation may all require different specimen preparation, contact materials, temperatures, cycle settings, liquids, and assessment procedures.

Start With the Color fastness Risk
The first step is to define the problem the lab needs to evaluate. If the concern is color rubbing onto another surface, crocking or rubbing fastness testing may be required. If the concern is color loss or staining after care, washing fastness testing may be more appropriate. Starting with the risk helps avoid choosing a method that does not match the product failure mode.
Match Contact Conditions and Test Parameters
Color fastness testing depends on controlled contact materials, specimen preparation, pressure, stroke geometry, temperature, time, liquid medium, agitation, and evaluation method. A proper setup helps reduce operator variation and supports better comparison between batches, suppliers, and production lots.
Consider Throughput, Repeatability, and Reporting
Laboratories should also consider how frequently tests will be performed and how results need to be documented. Routine QC testing may require repeatable cycles, consistent sample handling, and clear reporting procedures, while product development may require flexible equipment for comparing materials, finishes, dyes, and process changes.
Color Fastness Standards and Evaluation Methods
Color fastness testing may be performed according to AATCC, ISO, ASTM, or customer-specific procedures, depending on the material, product type, target market, and brand requirement. These methods can define sample preparation, contact material, washing conditions, temperature, rubbing direction, pressure, time, evaluation method, and reporting requirements.

Standard-Based Testing for Comparable Results
Standard-based color fastness testing helps laboratories control variables such as specimen size, contact material, rubbing pressure, washing temperature, exposure time, detergent or solution, agitation, and evaluation method. When these conditions are clearly defined and followed, quality teams can compare results more consistently across materials, suppliers, and production batches.
Application-Specific Testing Requirements
Not every textile or finished product requires the same color fastness program. A dark garment may require strong focus on washing and staining, while a footwear lining may require more emphasis on rubbing transfer under dry and wet contact. The most reliable approach is to select equipment around the exact material, expected use condition, and required test method.
