Factors Affecting the Rubbing Fastness of Flame Retardant Fabrics
Color fastness to rubbing has always been a major problem that has plagued the quality of flame retardant fabrics. The rubbing fastness of the flame retardant fabric depends on the amount of floating color and the molecular weight of the dye, the combination of dye and fiber, the uniformity of dye penetration, and the particle factor of the dye on the surface of the flame retardant fabric. The factors affecting the color fastness of the flame retardant fabric are mainly related to the friction of the surface of the flame retardant fabric, the amount of color of the colored textile and the fastness of the combination of the dye and the fiber.
The rubbing fastness test of flame retardant fabric is divided into dry rubbing fastness and wet rubbing fastness. The former is rubbing colored textiles with a dry white cloth; the latter is rubbing the dyed products with a white cloth containing 100% water. The wet rubbing fading of the flame retardant fabric is caused by the floating color transfer of the water-soluble dye and the mechanical friction transfer of the colored fiber particles under the action of friction. The wet friction has an external force and an aqueous medium, so the wet friction is generally dry. The rubbing fastness is about 1 level lower.
