Latest News and Updates on Textile Auxiliaries and Dyes

Part 1I have always wanted to discuss the decentralization of solvent dyes with my friends. However, I have been going out recently, so I did not find a suitable opportunity to write. Read More

Because at 130 ℃, the dyeing percentage of disperse dyes is the highest, with bright color, level dyeing and less floating color. 1) If the temperature is too high, the dye is easily decomposed and the fiber is easily damaged.2) If the temperature is too low, the dyeing rate is low and the dye penet Read More

1) Heating requirements:Control the temperature rise, otherwise the temperature rises too fast, which will cause the dye to be dyed too fast, resulting in chromatic aberration. ① Colored flowers: refers to the uneven dyeing and dyeing.② The purpose of heat preservation in the middle (90℃*5') is to m Read More

Estructura del colorante (pigmento), la estructura del colorante se divide básicamente en tres partes "grupo raíz cromóforo" "grupo raíz de reacción (unión)" "grupo raíz de conexión" Read More

El teñido en una máquina de desbordamiento, el calentamiento y el enfriamiento afectarán directamente la contracción de la fibra, lo que dará como resultado un pliegue. Para fibras termoplásticas como el nailon, una vez formado el pliegue, será irreversible. Por lo tanto, al teñir, se debe prestar e Read More

Solvent dye is a type of dye that can be dissolved in organic solvents. It is a very common type of dye. It is insoluble in water and can only be dissolved in organic solvents or oils. Read More

Solvent dye was originally named because it can be dissolved in various organic solvents. ) The dye in) is called Oil Dye (Oil Dye), and the dyes that can dissolve the polar solvents (ethanol, acetone) are called alcohol soluble dye. Read More

1) Chemical method: Cold water beating: warm water (<50°C = stir well, dilute and filter before adding to the dye vat for use. ① Add glacial acid first (add after dilution) to adjust the pH value (measure with pH test paper).② Add dissolved leveling agent and dispersant.③ Finally, add the well-dispe Read More

1. Pay attention to the cleaning of the conveying pipeline of the high temperature tank for dyeing and washing tanks.2. The materials and dyes are generally prepared 20-30 minutes in advance, stirred and dispersed evenly for use.3. The temperature of the chemical material should not exceed 50 °C, ot Read More

Polyester fiber with decentralized dyes dyed, during the dry heat treatment process, the phenomenon of decreased color targeting and color -light mutation. It is caused by the heat migration of decentralized dyes.The so -called heat migration refers to a phenomenon of migrating from the inside of th Read More

Disperse dye dyeing is mainly because polyester fiber dyeing is high -temperature and high pressure. Although the dye molecules are small, the dye molecules are not guaranteed to enter the fiber during dyeing. The cleaning is to destroy the dye molecules that are not entered into the fiber to improv Read More

Con el vigoroso desarrollo de la economía nacional y la mejora del nivel de producción nacional, el reconocimiento de los consumidores de la riqueza y viveza de los textiles ha continuado expandiéndose, y la demanda ha aumentado día a día. Con las características de alta intensidad de emisión, color brillante y fuerte fluorescencia, los tintes fluorescentes se utilizan ampliamente en el teñido y estampado de telas, además de la ropa de la policía de tránsito y el personal de mantenimiento vial, para satisfacer las necesidades diarias de los consumidores.
