After dyeing, the fabric's capacity to retain its original color can be represented by evaluating various color fastness. Washing fastness, rubbing fastness, light fastness, sublimation fastness, and other fabric indicators are commonly used for assessing color fastness. The greater the…
What is color fastness to rubbing? Rubbing color fastness refers to the color change degree of colored textile material caused by a certain way of rubbing with the small white cloth on a specific equipment. The color fastness of textiles…
The color fastness to rubbing of dyed products is divided into dry rubbing fastness and wet rubbing fastness. The former is to rub the dyed product with a dry white cloth to observe the color sticking to the white cloth.…
Color fastness to light is to measure the solar resistance of dyes and materials. The test method can be either sun exposure or solar machine exposure. The fading degree of the sample after sun exposure is compared with the standard…
What are the types of fastness? Color fastness, refers to the resistance of textile color to various effects during processing and use. The color fastness test of textiles is a routine item in the intrinsic quality test of textiles. Generally,…
Light fastness refers to the degree to which the color of the textile changes color under the action of sunlight or light after it has been dyed or printed. The factors affecting the actual test process of textile color fastness…
The elements influencing textile color fastness are classified as internal and exterior. Internal variables are the stiffness of the dye-fiber combination, whereas external elements are the external forces applied by external sources or the ambient conditions given by the product…
What is sublimation fastness Sublimation fastness is commonly associated with the dyeing of polyester disperse dyes. When the temperature rises above a certain point (setting above 180°C, ironing above 200°C), the disperse dyes in the polyester fibers directly convert from…
What is meant by light fastness Color fastness to light is the ability of a stain to retain its original color when exposed to sunlight. Due to the wave-particle biphasism of sunlight in nature, the sunlight that transmits energy in…
Color fastness to rubbing refers to the degree of color fading of dyed fabrics after rubbing, which is divided into color fastness to dry rubbing and color fastness to wet rubbing. It’s also known as color fastness to crocking. The…
Definition of colour fastness The so-called color fastness refers to the degree of fading of dyed fabric under the action of external factors (extrusion, friction, washing, rain, exposure, light, seawater impregnation, saliva impregnation, water stains, sweat stains, etc.) during use…
The color fastness of textiles to washing refers to the fabric's capacity to retain its original color under washing circumstances, that is, the ability to not fade or change color. Almost all textiles are washed in people's everyday lives. The…
