Latest News and Updates on Textile Auxiliaries and Dyes

Cuando se fabrica un tejido, existen una variedad de procesos a los que llamamos acabado a los que se les puede someter antes de su uso. Estos procesos pueden ser pretratamientos (preparation of fabric) como el decolorante (bleaching); la coloración (dying), serigrafiado (printing), o acabados (finishing). Hoy vamos a hablar sobre el acabado químico de los tejidos. Read More

No matter what kind of dyeing bath ratio is not a single stipulation, it should be determined by the dyeing and finishing company according to the processed products when formulating the process. For dyeing light and thin polyester fabrics with a weight of 60~100g/㎡, the bath ratio is generally cont Read More

1. Color matching principleIn daily production, there are more and more varieties of textile colors. Many colors can't be dyed with a single dye. They must be solved by color matching. In the process of specific color matching, the three colors of red, yellow, and blue are often referred to as the t Read More

Use of solvent dyesThe solvent DYESTUFF, as an organic redissolvable dye, is easily soluble in general organic solvents such as ethanol, BTX, ketone, ester, oil and paraffin, and has the advantage of bright colors. These dyes come in many series and have many uses.Solvent dyes are widely used oil-so Read More

The alkaline dyeing method has the advantages of effectively removing oligomers, shortening the dyeing time, stabilizing the color and saving energy and so on. 1. It can further improve the refining effect:Because there are more oils on synthetic fibers, it is difficult to completely remove the rema Read More

Measures to improve textile pH unqualified:1. Acid-base neutralization: neutralization by adding alkali for more acidic, neutralization by adding acid for more alkaline, generally used acid is acetic acid or citric acid, and alkali is soda ash.2. Improvement of dyeing and finishing process: increase water washing, etc. Choose high-quality raw materials, dyes, etc., and eliminate them from the source. Read More

Types of cationic dyesCationic dyes can be classified according to two classification methods: application performance and chemical structure type. According to the application performance, China divides the existing dyes into ordinary type, X type and M type. According to the chemical structure, it Read More

As the global economy recovers from the epidemic, the Turkish textile industry hopes to open a new era of cooperation with international companies and brands, with production capacity exceeding US$100 billion.

Key points of chemical material operation1. Check the accuracy of the prepared dyes and chemicals according to the prescription list. When disperse dyes are used to make materials, generally use cold water to beat them and mix them evenly (stirring with a mixer for about 20-30 minutes), and then dil Read More

What is Amylase and its application? Amylase is the general name of enzymes that hydrolyze starch and glycogen. It usually catalyzes the hydrolysis of starch slurry on fabrics by amylase. Due to the high efficiency and specificity of amylase, the desizing rate of enzyme desizing is high and the desi Read More

What is Desizing? Desizing (desize) refers to the process of treating fabrics with acids, alkalis, enzymes, etc., to remove the slurry rhyme added to the warp yarns during weaving. The purpose is to facilitate subsequent processing such as refining. Before fabric weaving, warp yarns are generally su Read More

The nature of cationic dyesSolubilityThe salt-forming alkyl and anionic groups in the cationic dye molecule affect the solubility of the dye. In addition, if there are anionic compounds in the dyeing medium, such as anionic surfactants and anionic dyes, they will also combine with cationic dyes to f Read More
