The Importance of Color Fastness in Fabric Specifications

March 18, 2024

In fabric specifications, there are numerous critical indicators such as yarn density, tensile strength, tear strength, shrinkage rate, and color fastness, each directly impacting the quality and performance of the fabric. However, among these indicators, color fastness stands out as particularly crucial, directly influencing the fabric's lifespan and visual appeal.


Color fastness refers to a fabric's ability to maintain color stability under different conditions, serving as a significant criterion for measuring fabric durability and quality. Good color fastness implies that the fabric can retain stable colors during washing, exposure to sunlight, friction, perspiration, etc., thus prolonging its lifespan and preserving its aesthetic appeal. There are four types of color fastness commonly required for accessing fabric’s color stability which are color fastness to washing, to light, to crocking, and to perspiration. Color fastness to washing assesses the fabric's ability to maintain color stability during the washing process, while color fastness to light evaluates its resistance to color fading when exposed to sunlight or artificial light sources. Color fastness to crocking measures the fabric's resistance to color fading or staining when subjected to friction with other surfaces. Color fastness to perspiration evaluates how the fabric maintains its color stability when in contact with sweat, reflecting its durability and appearance during wear.


As a professional workwear and uniform supplier, Bscam has implemented stringent color fastness standards for our polyester wool blend fabric, polyester cotton blend fabric, and nylon cotton blend camouflage fabric to ensure product quality and performance. Our factories utilize advanced testing methods and equipment to conduct thorough inspections on each batch of fabric, ensuring that their color fastness meets relevant standards and requirements. Below is the color fastness test report for shipment of our NylonCotton camouflage fabric. For the test results of shipments for our PolyWool and PolyCotton Fabric, you can check in About Us/Inspection for details. Overall, they demonstrate excellent performance in the SGS lab. tests of color fastness to crocking, to light, to washing and to perspiration, with ratings reaching 4-4.5 grade.



Color fastness plays a crucial role in fabric specifications, ensuring product quality and performance. Bscam will continue to focus on improving color fastness to meet customer demands and provide high-quality uniform and workwear fabrics.
