The differences among color fastness, color durability, and staining fastness

The differences among color fastness, color durability, and staining fastness
Color fastness, also referred to as dyeing fastness or color durability, refers to the resistance of a textile’s color to various factors encountered during processing and use. The fastness grade is determined by assessing the degree of color change in the test sample and the level of staining on the undyed backing fabric. Color fastness testing is a routine quality-control procedure in the evaluation of textile intrinsic quality.

What is a jump light, and how can it be resolved?

What is metamerism? Imagine two color swatches that appear to match under D65 illumination but exhibit a noticeable color difference under TL84 illumination—this is the phenomenon of metamerism, also known as color mismatch. The Metamerism Index (MI) is a key metric for quantifying this phenomenon, reflecting the degree of color variation under different light sources. The higher the MI value, the greater the risk of metamerism.

Causes, Testing, and Solutions for Yellowing of Textiles

Causes, Testing, and Solutions for Yellowing of Textiles

The phenomenon in which white or light-colored materials develop a yellowish tint on their surface under external conditions such as exposure to light or chemical agents is known as “yellowing.” When white and dyed textiles yellow, not only is their appearance compromised, but their service life is also significantly reduced. Consequently, research into the causes of textile yellowing and strategies for preventing it has long been a popular topic both domestically and internationally.

Dye Knowledge | Sulfur Dyes

Dye Knowledge | Sulfur Dyes

Sulfur dyes are a class of sulfur-containing dyes with relatively complex molecular structures. They are typically produced by heating certain organic compounds, such as aromatic amines and amino phenols, together with elemental sulfur or sodium polysulfide, a process known as sulfuration. Most sulfur dyes are insoluble in water; during dyeing, they must be dissolved in sodium sulfide or an alkaline hydrosulfite solution to be reduced to a leuco form, which is then absorbed by the fiber and subsequently oxidized to develop color.
