Dye Color Fastness - a property of keep original dye color

Dye color fastness refers to the ability to keep original dye color under the influence of other kinds of external factors in the use or late processes of dyeing textiles. It is an important indicator to measure the quality of dyeing products. The requirement to dye color fastness varies from the application of dyeing textiles.

Due to the use of chemicals in the late processes of dyeing and finishing, like acid, alkali, oxidants, reductants,etc, and when using in washing, sunlight, rubbing, sweat, high temperature and so on, dyeing textiles may fade or discolor. Therefore, dye color fastness is diverse, including washing fastness, light fastness, rubbing fastness, perspiration fastness, chlorine fastness, ironing fastness, etc.

I think the color fastness grade was evaluated based on the discoloration of the sample and the coloration of the unstained fabric. Among them, the color fastness to perspiration, the light fastness and the rub fastness are closely related to our daily lives. If you want to know more about Perspiration Tester, please come to:
