There are many kinds of dyes in stretch lace trim wholesale, but in terms of the physical form of its commodities, can be divided into solid, liquid and pulp.

Dyes are organic compounds, often in the presence of liquid conditions to complete the chemical reaction, so the world's first synthetic dyes were first sold in liquid form, and these liquid dyes are mainly VAT dyes and mordant dyes.

In 1923, the British first added the selected auxiliary agent into the original dye and crushed it to make the insoluble disperse dye aqueous dispersion. However, the original powdery dye had the disadvantages of severe dust emission and poor wettability.

Now the liquid dye after optimized processing formula of various properties have been significantly improved, storage time can reach more than half a year without deterioration, liquid dye processing cost is low, easy to use and has been constantly developed. the progress of chemical machinery, chemical equipment, now many dyes are processed into granular goods.

The research content of dyestuff processing technology mainly includes the determination and treatment of the original dyestuff, the research on the properties of processing additives, the design and selection of processing equipment and the research on processing technology.

Dye processing involves several aspects embrodiery lace wholsale.

1. To test and analyze the physical and chemical properties of raw dyes for the purpose of dye processing.Including the intensity of the original dye, color light, hydrophilicity, crystal type, energy level, impurity content and many other indicators.

2. A substance added during the post-processing of a dye to improve the performance of a specific dye commercial formulation or to improve the performance of a given dye and the dyeing properties on the fiber.

3. Processing equipment (post-processing equipment) is an important means to complete post-processing operations. Reasonable design and selection of processing equipment are the primary conditions for successful completion of post-processing operations.

4. Processing technology is a method for the comprehensive application of the above three parts.Practice has proved that the same raw dyes, auxilaries and equipment, using different processing technology to get completely different results in dyeing china chemical lace trim, it can be seen that the importance of process conditions.From the above introduction, it is not difficult to see that these four aspects mark the technical level of post-processing.
