Color bleeding or dye hydrolysis is one of the leading causes of garment returns and buyer complaints in the textile industry. Learn the scientific causes of color bleeding, lab testing methods, international standards, prevention techniques and how Darong’s advanced instruments help manufacturers ensure superior colorfastness and global quality compliance.
What is Color Bleeding in Garments?
Color bleeding is the unwanted transfer of dye from a dyed textile to another fabric or an adjacent area during washing, rubbing, perspiration or exposure to water, and it usually occurs when unfixed or loosely bonded dye molecules migrate from the fabric surface under these conditions.
Bleeding of color can lead to customer dissatisfaction, product returns, shipment rejection and damage to the manufacturer’s reputation and performing proper lab evaluation is very important before commercial production.
The Science Behind Color Bleeding in Garments
The performance of the dyed or printed fabrics depends on the strength and interaction between the dye molecules and the fibers, and if the dye molecules are not completely fixed, there will be unfixed dye molecules on the surface of the fabric and washing or rubbing will cause these unfixed dye molecules to dissolve into water or transfer mechanically onto the adjacent material.
There are many scientific factors that influence the bleeding of the color, such as:
- Low fixation efficiency
- Improper washing off after dyeing
- Improper selection of the dye molecules
- Excessive concentration of the dye molecules
- Poor affinity between the dye and the fiber
- Incorrect dyeing parameter
- Incomplete soaping process
Which Textile Products Are Most Susceptible to Color Bleeding in Garments?
Although bleeding of the color may occur in any dyed or printed textile, it is common in:
- Dark-colored garments
- Denim products
- Reactive dyed cotton fabrics
- Printed textiles
- Towels
- Home textiles
- Sportswear
- A garment with a contrasting combination of colors
What Causes Color Bleeding in Garments?
There are many manufacturing and processing factors that contribute to poor colorfastness and dye migration included:
- Poor dye fixation
- Improper washing off
- Incorrect dye selection
- Improper dyeing parameters
- Excessive dye concentration
Why Does Color Bleeding Lead to Customer Complaints?

Each and every consumer expect garment to retain its original appearance after repeated washing, and color bleeding can result in:
- Staining of adjacent garments
- Color transfer onto white fabrics
- Consumer dissatisfaction
- Product returns
- Brand reputation damage
- Shipment rejection
- Retail quality claims
How is Color Bleeding Tested in a Textile Lab?
The general testing procedure of the color fastness test is:
- Conditioning the testing specimen under standard atmospheric conditions
- Washing or rubbing the testing specimen under specified lab conditions
- Placing the adjacent multifiber in contact with the testing specimen
- Assessing the staining and color change using the standardized Grey Scale
International Standards for Color Bleeding Testing
There are many internationally recognized standards that are used to evaluate color bleeding resistance, including:
- ISO 105-CO6 (Colorfastness to domestic and commercial washing)
- AATCC TM61 (Colorfastness to laundering)
- ISO 105-X12 (Colorfastness to rubbing
- AATCC TM8 (Colorfastness to crocking)
- ISO 105-E04 (Colorfastness to perspiration)
How to Prevent Color Bleeding in Garments?
Textile manufacturers can minimize color bleeding by improving the dyeing processes and quality control procedures, and the effective preventive measures include:
- Selecting the high-quality dyes with excellent fixation properties
- Optimize the dyeing parameters such as temperature, pH and dosing of auxiliaries
- Performing proper washing-off and soaping treatments
- Using the best quality dye fixation chemicals
- Controlling the process consistency
- Conducting lab testing
- Verifying compliance with the buyer’s specification before shipment
How Darong Textile Testing Instruments Help Prevent Color Bleeding Problems
Darong offers advanced textile testing instruments for evaluating colorfastness, rubbing fastness, washing fastness, perspiration fastness, shrinkage, tensile strength, pilling resistance, air permeability, moisture management and other critical fabric properties.
These advanced lab solutions enable textile manufacturers to optimize all processes from greige yarn to dyed and finished products, verify compliance with ISO and AATCC standards, reduce customer complaints and minimize shipment rejection risks.
Conclusion
Color bleeding is one of the common quality defects affecting dyed textiles and garments. IT primary results from the poor dye fixation, inadequate washing off, improper selection of the dye molecules and uncontrolled processing conditions. By understanding the scientific causes of dye migration and implementing standardized lab testing, manufacturers can identify and resolve issues before shipment. Advanced Darong textile testing instruments provide an accurate, repeatable and standard-compliant testing solution that improves color fastness performance, reduces product returns and helps exporters meet international buyer requirements.
FAQs
What is color bleeding in garments?
Bleeding of color is the transfer of dye molecules from a colored fabric to another fabric or an adjacent area during washing, rubbing, perspiration, or water exposure. It occurs when unfixed dye molecules migrate from the fabric’s surface, causing staining and reducing the overall quality of the garment.
What caused color bleeding in fabrics?
Color bleeding is mainly caused by poor dye fixation, improper washing off after dyeing, excessive dye concentration, improper dye selection, incorrect dyeing conditions and insufficient soaping.
What is the difference between color bleeding and color fading?
Color bleeding is usually the transfer of dye molecules from one fabric to another, and color fading is the loss of a color’s intensity in the original fabric due to washing, sunlight or chemical degradation.
How is color bleeding testing conducted in textile laboratories?
With the help of standardized color fastness tests such as ISO 105-C06, AATCC TM61, ISO 105-X12, and AATCC TM8, the testing specimen is subjected to washing or rubbing under controlled conditions, and the degree of color transfer to adjacent fabrics is assessed using Gray Scale ratings.
How can textile manufacturers prevent color bleeding?
Textile manufacturers can minimize color bleeding by selecting high-quality dyes, optimizing dyeing parameters, maintaining the correct pH and temperature, performing efficient washing-off and soaping, and conducting lab color fastness testing before bulk production and shipments.
Which international standards are commonly used for color bleeding testing?
The widely used testing standards are ISO 105-C06, ISO 105-X122m ISO 105-E04, AATCC TM61 and AATCC TM8 and these methods are recognized by international brands and retailers around the globe.
How do Darong textile testing instruments help reduce the color bleeding problems?
Darong instruments provide accurate and repeatable evaluation of washing fastness, rubbing fastness, perspiration fastness and other color performance properties as per ISO and AATCC testing standards and combined with Darong conditioning chamber and quality control equipment, these machines help manufacturers to optimize dyeing processes, verify color fastness, reduce color bleeding risks and improve the compliance with international buyer requirements.
