"Textile color standard system"
Color fastness refers to the resistance of the color of the textile to various effects during processing and use. The fastness rating was determined according to the discoloration of the sample and the staining of the unstained fabric. Textile color fastness test is a textile internal quality testing in a routine testing project
Because the fabric in the processing and use of the conditions encountered by the difference is very different, different requirements, so the current test methods are mostly according to the role of the environment and conditions for simulation or comprehensive test, so the color fastness test method Content is quite extensive.
The so-called color fastness (referred to as color fastness), refers to the dyeing fabric in the use or processing process, subject to external factors (extrusion, friction, washing, rain, exposure, light, sea water immersion, saliva impregnation, Etc.) under the effect of the degree of fading, is an important indicator of the fabric.
The dye molecules and heavy metal ions are likely to be absorbed by the skin and endanger the health of human skin, on the other hand will affect the other clothing worn on the body was stained, or with other clothes when washing dirty other clothing The
Color fastness and poor, directly related to the health and safety of the human body, poor color fastness in the process of wearing, run into the rain, sweat will cause the fabric off the paint off,
