Latest News and Updates on Textile Auxiliaries and Dyes

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.

El proceso de laminación en frío es un proceso de procesamiento a temperatura ambiente. Debido a que la tecnología del proceso de laminación en frío tiene muchas ventajas, como un bajo costo de inversión, bajo consumo de energía, bajo consumo de agua, alta flexibilidad y productividad, fuerte adaptabilidad al proceso y pequeña pérdida de resistencia de la tela, actualmente se usa en algodón. Es ampliamente utilizado en pretratamiento, teñido, estampación y acabado en teñido y acabado de tejidos. Read More

①Innumerable products of any type of dye have been developed, but not many products are suitable for the commercial market. If the global dye companies that are suitable for commercialization are competing to imitate them, some of them only slightly change the chemical structure of the dye in order Read More

Dye (pigment) structure, the dye structure is basically divided into three parts "chromophore root group" "reaction (bonding) root group" "connecting root group"Chromophore: Light (photons) can be irradiated on this chemical structure (photons hit the chromophore, resonate and emit a specific wavele Read More

Acid dyeing of protein fibers, in addition to the composition, chemical properties and physical state of the fibers and dyes themselves have a direct impact on the dyeing, external conditions such as pH value of the dye solution, temperature and the addition of electrolytes also directly affect the Read More

1. Color fastness to washingThe specimens are sewn together with a standard backing fabric, washed, washed and dried, and washed at the appropriate temperature, alkalinity, bleaching and rubbing conditions to obtain test results in a relatively short period of time. The friction between them is acco Read More

After dyeing of textiles, the ability of fabrics to retain their original color can be expressed by testing various dye fastnesses. Commonly used indicators for detecting dyeing fastness include washing fastness, rubbing fastness, light fastness, sublimation fastness and so on.The better the washing Read More

(1) Physical properties of disperse dyes:Wetting, dispersibility, particle fineness, dispersion stability, etc. These properties will affect the preparation of the dye solution and are the main factors for the formation of dyeing spots.(2) High temperature dispersion stability of disperse dyes:Repre Read More

Appearance: A group of several or dozens of fabrics, after continuous dyeing under the same set conditions, the beginning and the end of the dyed fabrics, there are shades of difference in color.Causes: 1). In the pretreatment process, there are differences in desizing, scouring, bleaching, merceriz Read More
