Textile color fastness, also known as the color fastness, refers to the color of colored fabrics against the outside world without the ability to change the role of color in recent years in the international textile and garment trade, the color fastness requirements in addition to ensuring product quality, But also continue to pay attention to its safety and environmental protection. GB on the color fastness requirements of the project for water; resistant to dry friction, moisture friction. EU eco-textile logo requirements of the color fastness in the national standard on the basis of an increase of sun color fastness, and perspiration color fastness.
 
Color fastness detection process:
Washing Fastness: Samples are stitched together with standard backing fabric, washed, washed and dried, washed at the appropriate temperature, alkalinity, bleach and rubbing conditions to obtain test results in a short period of time . During which the friction is through the small bath and the appropriate number of stainless steel beads rolling, impact to complete, with gray card rating, the test results. Different test methods have different temperature, alkalinity, bleaching and friction conditions and sample size, according to the specific test criteria and customer requirements to choose. Generally washed color fastness of the color are Cuilan, Yan Lan, black red, dark blue and so on.
Dry-cleaning color fastness: the same as washing fastness, just washed into dry cleaning.
In this case,
Friction color fastness: the sample on the friction fastness meter, in a certain pressure with a standard friction with a certain number of friction white cloth, each group of samples are required to do dry friction color fastness and wet friction color fastness. The standard color of friction on the white cloth with the gray card to be graded, the resulting series is the measured color fastness to rubbing. Friction color fastness need to do dry friction and wet friction two tests, all the samples on the color to be friction to.
In this case,
Color fastness to sunlight: textiles in use are usually exposed to light, the light can damage the dye which leads to the well-known "fade", so that colored textiles change color, generally lighter, darker, and some will appear shade changes, so , You need to test the color fastness, sun color fastness test, the sample is different with the fastness of the series of blue wool standard cloth with the required conditions under the sun exposure, the sample and blue wool Cloth for comparison, assessment of light fastness, blue wool, the higher the standard fabric of the more light-resistant.
Perspiration color fastness: the sample and the standard bonded fabric stitched together, placed in the perspiration solution, the folder in the color fastness to perspiration, placed in the oven temperature, and then dry, gray card with a rating, Get the test results. Different test methods have different perspiration ratio, different sample size, different test temperature and time.
In this case,
Color fastness to water: Tested with water as above.
Chlorine bleach fastness: the chlorine bleach in the fabric according to certain conditions after washing to assess the degree of color change, which is chlorine bleach fastness.
Non-chlorine bleach fastness: the fabric with non-chlorine bleaching washed under the conditions of washing, to assess the degree of color change, which is non-chlorine bleaching fastness.
In this case,
Color fastness: The dry specimens were covered with cotton-lined fabric, pressed in a heating device at the specified temperature and pressure for a certain period of time, and then the discoloration of the samples and the staining of the adjacent fabrics were evaluated using a gray-colored sample card. Hot pressing color fastness of dry pressure, tidal pressure, wet pressure, according to different customer requirements and test criteria to select the test method.
