For example: S or H means high temperature type, SE or C means medium temperature type, E means low temperature type It is generally believed that the molecular weight above 300 is Read More

The disperse dye attached to the surface of the fiber will be "reduced" to become colorless and more soluble in water.Traditional reduction cleaning method: using hydrosulfite and caustic soda for treatment. 1. 100% polyester fabric reduction cleaning process: 2. Polyester/cotton blended reduction c Read More

Disperse dyes can be divided into three categories according to their heat resistance in application: 1. Low temperature type (E type)Low fastness to sublimation, good leveling performanceSuch as red-60#, blue-56#, yellow-54#, orange-25#, etc., because the molecular weight of these dyes is relativel Read More

It can be used directly in medicine or in the processing of traditional Chinese medicine and cosmetics. It has a wide range of applications in daily life. Efficacy and function Read More

Teñido de spandex con colorantes dispersos, las condiciones óptimas del proceso son: temperatura 125 ℃, tiempo 30～40min, valor pH 5～6. La temperatura de teñido debe controlarse dentro del rango de 120 a 130 °C. Cuando la temperatura es inferior a 120 °C, la solidez del color no es suficiente y es fácil de decolorar; cuando es superior a 130 °C, la profundidad del color de la superficie y la solidez del color disminuirán significativamente, y cuanto mayor sea la temperatura de teñido, más duro será el spandex. Cuanto menor sea el grado de enlace de hidrógeno entre los segmentos, menor será la cristalinidad del segmento duro y más grave será el daño a sus propiedades mecánicas y estructura. Read More
