Soaping fastness refers to the degree of fading of dyed fabrics after soaping in soap solution under specified conditions. It includes the original fading and white cloth staining. Original fading refers to the fading of printed and dyed fabrics before and after soaping. White cloth staining is a si Read More

The fading and discoloration of dyed fabrics is a relatively complicated process. Under the action of sunlight, the dye absorbs light energy and the molecule is in an excited state. It is unstable. The energy obtained must be released in different forms to become a stable state. One of the forms is Read More

According to a Bloomberg report, although the soaring freight rates have brought huge profits to container shipping companies such as Maersk Group and COSCO Shipping Holdings, importers are also facing higher costs that are more difficult to digest. Some companies have raised retail prices, intensif Read More

1. Dyeing process The dyeing process can be roughly divided into three stages: A. Absorbing Adsorption is the process in which the dye attaches to the surface of the fiber; the dye is adsorbed by the fiber in the solution due to the intermolecular force and the electrostatic attraction between ions.

As direct dyes and other accelerating agents for cotton dyeingWhen dyeing cotton with direct dyes, sulphur dyes, vat dyes and Yindioxin dyes, sodium sulfate can be used as a dye-promoting agent.These dyes are easy to dissolve in the prepared dyeing liquor, but not easy to dye cotton fibers. Because Read More

The super-commodity cycle was too much to steal the spotlight, but the volatility of the foreign exchange market was ignored-the weaker dollar indirectly stimulated the rise of commodities, and the renminbi also went crazy silently.As of 16:30 on May 10, Beijing time, the onshore renminbi closed at Read More

The dyeing mechanism of reactive dyes on cellulose fibers is different from other dyes. As a result of dyeing, the dyes on the fibers are not physically dyed on the fibers by hydrogen bonds, ionic bonds or van der Waals forces, but in the form of covalent bonds. It is chemically combined with the fi Read More

Lifting powerLet's first look at the lifting power of disperse dyes, which is one of the important properties of disperse dyes. The lifting power is good, indicating that there is a good deep dyeing property. So what is the effect on dyeing? In fact, the lifting power of different varieties is very Read More

Traditional disperse dye printing has been extended for many years: screen printing → steaming (color development) → washing (removing paste and floating color) → drying and setting. Among them, the sewage discharge from the washing process is the main cause of printing sewage. Since the printed pro Read More

Facing the irresponsible over-issuance of the U.S. dollar, countries should reduce their holdings of U.S. dollar assets and resist the U.S. dollar he Read More

1. Choose reactive dyes with less floating color after dyeingFloating color is the main reason for the unqualified wet rubbing fastness of dark and dense fabric.The floating dyes of reactive dyes include dyes that have been adsorbed on the fibers without reacting with the fibers, partially hydrolyze Read More

Direct dye was developed after Bottiger discovered Congo Red in 1884. Before this, cotton fibers were dyed with indigo and other natural dyes, which was troublesome. At that time, synthetic dyes were just beginning to be developed, and cotton fibers could not be dyed directly. The cotton fibers must Read More
