Под текстильными волокнами обычно понимают объекты диаметром в несколько микрометров или десятков микрометров и длиной, во много раз превышающей диаметр. Текстильные волокна должны иметь определенную тонкость и длину, чтобы волокна могли сцепляться друг с другом и полагаться на трение между волокнам Read More

Color fastness to rubbing is also called color fastness to rubbing. The main influencing factors are the structure and properties of dyes, the organizational structure of different fibers and fabrics, and the dyeing process. Reactive dyes contain hydrophilic groups such as sulfonic acid groups. If t Read More

Color fastness to light is also called light fastness or light fastness. The main factors affecting fading under sunlight include light, molecular structure of dyes, dye aggregation state and dyeing depth, and fiber properties. Light is the most important factor causing dye fading. The chromophore g Read More

Cotton fiber belongs to natural cellulose fiber. Cotton fabric has soft hand feel, good moisture absorption and air permeability and excellent wearing performance. As people pay more and more attention to wearing health and advocating nature, cotton fabric is loved by people. Reactive dyes are one o Read More

1 Choose the right dyeThe color fastness is closely related to the structure of the dye, and the selection of the dye should consider:① Strong reactivity between dyes and fibers;②High fixation rate;③It has better acid-base stability;④ The bond energy of the covalent bond of the dye-fiber is high, th Read More

En la inspección de calidad de la solidez del color textil, la solidez del color al frotamiento es uno de los elementos de inspección más importantes, y el resultado de la prueba está directamente relacionado con la solidez general del color de la tela. Debido a que algunos colorantes con poca solidez del color pueden causar diferentes grados de daño al cuerpo humano, diferentes organismos normativos y países han formulado estándares para esto, limitando estrictamente los niveles de solidez del color de la ropa y los textiles para el hogar.
