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

The cationic dye can be dissolved in water. In the water solution, it is mostly used in the water solution that is mainly used for the dyeing of acrylic. Read More

As a part of organic pigments, solvent dyes have the properties of organic pigments, and also have their own characteristics. When coloring with the same color, solvent dyes have a color-enhancing function, and their strength is much higher than that of organic dyes. They can be used for transparent Read More

There are many factors that affect the dye dyeing process, mainly including: 1. Dye propertiesThe dye structure and molecular size and shape determine the solubility, diffusionability of dyes, and the height of dyes and fibers. Second, the nature and concentration of the aidThere are many categories Read More

El tinte catiónico tiene una gran afinidad por el acrílico. Cuando el teñido es rápido, se extiende lentamente debido a la rápida adsorción, que es propensa a teñir el fenómeno desigual. Una vez que el teñido es desigual, es difícil corregirlo extendiendo el tiempo de teñido. Al teñir el colorante c Read More

There are many factors that affect the dyeing process, mainly including: 1. Properties of dyesThe dye structure and its molecular size and shape determine the solubility, diffusibility and affinity of the dye to the fiber. 2. The nature and concentration of additivesWhether it is in the dye or in th Read More

En 1935, el Dr. Carothers, los científicos estadounidenses y su equipo desarrollaron poliamida, comúnmente conocida como "nylon". Read More

If it is a re-ordered color that is frequently produced, the pre-treatment process must be stable and consistent to ensure that the semi-finished products produced each time have the same gross effect, whiteness, and pH value. And each time before dyeing, the laboratory needs to make a sample, and t Read More

Acid dyes refer to the acid group in the dye molecules, also known as anion dye, which can be combined with amino groups in protein fiber molecules. Read More

Scouring pleats are mostly found in high-count and high-density polyester-cotton fabrics and pure cotton thin fabrics. Due to the high hardness of water during production, scale is easy to form during steaming and washing and is easy to adhere to the cloth guide roller. Long-term production will for Read More

1. Unqualified color plasticityThe color fastness includes sun exposure, soap washing fastness, sweat staining fastness, friction fastness, sublimation fastness, ironing fastness, etc. These fastness is The dyeing process and external conditions are closely related. Therefore, whether the color fast Read More

1. Descripción general de los tintes ácidos Los colorantes ácidos se refieren al grupo de ácido en las moléculas de colorante, también conocido como colorante de anión, que se puede combinar con grupos amino en moléculas de fibra de proteínas con enlaces iónicos y aplicables bajo ácidos ácidos.
