Latest News and Updates on Textile Auxiliaries and Dyes

Because the amino groups and carboxyl groups at both ends of the macromolecules of nylon fibers are sensitive to light, heat and oxygen, especially the amino groups, the number of groups will decrease during the process of oxidation and thermal cracking. Nylon fibers also turn yellow at the same tim Read More

1. The effect of pH value of dye solution on dyeingThe industry has always believed that the control of the pH value of nylon dyeing is the key to success or failure. After years of production accumulation, we found that if the buffer system auxiliaries and the selection of good leveling agents are Read More

When the medium temperature reactive turquoise blue is dip-dyed, the reason why it is easy to produce color spots and stains is because the reactive turquoise blue has the defects of salt resistance and poor alkali dissolution stability. The medium-temperature active turquoise blue has good salt-dis Read More

1.1 Fixed-length titer unitDenier (D): Refers to the weight in grams of a 9000-meter-long fiber or yarn at a given moisture regain. For example: 1500D polyester raw silk means that the raw silk is measured 9000 meters, and its weight is 1500 grams. Others follow and so on.Special number (tex): also Read More

1) Twisting length of the bobbin: the length of the fiber or yarn wound on the bobbin after twisting. 2) Wool: The cord is fluffed due to yarn abrasion or raw silk. 3) Oil stained yarn: Yarn contaminated by oil. 4) Wrong denier silk: The same kind of raw silk in production, different deniers are not Read More

Fluorescent Dyes: Dyes that strongly absorb and radiate fluorescence in the visible light range.The fluorescent reflectance of fluorescent dyes on fabrics depends on the intensity of the ultraviolet light source, the amount of fluorescent substances dyed on the fabrics and the fluorescent quantum ef Read More

1. Water inlet and liquid level control before the fabric is put into the tank During airflow dyeing, before the fabric enters the tank, the water inlet valve is first opened through the control system to enter the water. The amount of water entering is automatically controlled by the electrical con Read More

Dyeing fee calculation:Textile dyeing costs are mainly affected by the dyeing method, dye selection, dyeing process, fabric specifications, and color depth. 1. Dyeing method 1.1 Pad dyeing Under normal circumstances, pad dyed cotton fabric has good dye fastness and the surface of the fabric is smoot Read More

Light fastness Sunlight has wave-particle duality, and the sunlight that transfers energy in the form of photons has a strong impact on the molecular structure of the dye. When the basic structure of the coloring part in the dye structure is destroyed by photons, the color of the light emitted by th Read More

1. The choice of dye or paintThe light-fading mechanism of dyes is very complicated, but the main reason is that the dyes are excited after absorbing photons, and a series of photochemical reactions occur to destroy the structure, leading to discoloration and fading. The light fastness of textiles m Read More

Flat screen printing featuresThe printing method of the flat screen is that after the scraper runs in the weft direction, the cloth surface moves forward after the screen is lifted up and down, which is more suitable for patterns that express the pattern effect in the warp direction.Because it is a Read More

By analyzing the factors of the pH value of nylon cloth in production, such as bath ratio, acid used in the bath and acid dosage, etc., suitable production conditions are formulated to overcome the shortcomings of sourness, yellowing in storage and unstable pH value of nylon finished cloth. After ad Read More
