Household textiles will inevitably be exposed to various external effects such as light, washing, ironing, perspiration, friction and chemicals during use. Under these effects, household textiles will inevitably fade, and even dye other things, so The color fastness to rubbing of household textiles is required.
The clothes are subjected to factors such as friction, water immersion, perspiration and the like during the wearing process. When the dye and the fabric are not firmly combined, they will migrate to the human skin. Due to the sweating of the human body and the catalysis in the saliva, the dye can be decomposed. It is harmful to human health.
Color fastness is a general term, the color fastness of textile is the color fastness (referred to as color fastness), and the simulated dyed fabric is subjected to external factors (extrusion, friction, water washing, rain, exposure, light, seawater impregnation) during use. The degree of fading under the action of saliva, water stains, perspiration, etc. is an important indicator of fabrics. The color fastness is 5 grades, etc., (1, 1-2, 2, 2-3, 3, 3-4, 4, 4-5, 5) The 1st grade is the worst, the 5th grade is the highest, almost impossible .
The detection of color fastness is a very complicated work, and it is usually sent to a professional testing institution. In addition to the three commonly used color fastness tests, such as washing, light and rub resistance, the color fastness test should be strengthened. It is resistant to water, perspiration, acid spots, alkali spots, hypochlorous acid bleaching, peroxide bleaching and formaldehyde resistance.
