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…
Introduction Nanofiber materials have the advantages of large specific surface area, high porosity, low density, good mechanical flexibility and so on, which show broad application prospects in many fields. There are various methods for preparing nanofiber materials, including electrospinning, solution…
Air flow dyeing is a modern dyeing process that has a low liquor ratio, reduced energy consumption, and less pollution, and is regarded as an environmentally friendly dyeing method in the twenty-first century. The characteristics and mechanisms of air flow…
