Latest News and Updates on Textile Auxiliaries and Dyes

For fabrics with slight chromatic aberration, the following methods can be used: When the exhaustion rate is reduced and a large amount of dye remains in the residual liquid, it can be adjusted by extending the dyeing time or increasing the dyeing temperature. When the dyeing depth is slightly highe 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

What is Polyurethane (PU) and its application? Polyurethane (PU), whose full name is polyurethane, is a polymer compound. It was produced in 1937 by Otto Bayer and others. Polyurethane has two categories: polyester type and polyether type. They can be made into polyurethane plastic (mainly foam), po Read More

En un colorante reactivo, un cromóforo (un átomo o grupo cuya presencia es responsable del color de un compuesto) contiene un sustituyente que reacciona con el sustrato. Los colorantes reactivos tienen buenas propiedades de solidez, debido a la unión que se produce durante el teñido. Los colorantes reactivos son los más utilizados en el teñido de celulosa como el algodón o el lino, pero también lana es susceptible de teñido con colorantes reactivos. En este informe se estudia el mercado Colorantes reactivos. Read More

Thermal migration is a redistribution phenomenon of disperse dyes in two-phase solvents. Therefore, all additives that can dissolve disperse dyes can produce thermal migration.The reason for the thermal migration phenomenon is that the auxiliary agent in the outer layer of the fiber dissolves the dy Read More

Also called enzyme washing, enzyme is a kind of cellulase, which exists in natural organisms and is a natural and healthy beneficial enzyme. It can degrade the fiber structure under a certain pH value and temperature, so that the cloth surface can be faded more gently, and a lasting soft effect can Read More

Levelling agent In the printing and dyeing process, pay attention to the phenomenon of uneven dyeing or staining. Leveling agent means that the dyeing can delay the dyeing speed of the fiber (retarded dyeing), and can make the dye transfer from the high concentration of the fiber to the fiber. It is Read More

What is compound silicone oil and its application? The compound silicone oil is a colorless and transparent oily liquid with a freezing point of -4°C without freezing, and the ionic type is anionic and non-ionic. Compound silicone oil is a macromolecular material compounded with polymethylsiloxane. Read More

1. The choice of dye: a. Reactivity: medium degree; b. Directness: medium to low. In addition, the fixation rate of the dye itself must be considered: if the fixation rate is too low, the amount of dye is large, which is not conducive to post-washing. Generally speaking, the domestic m-type and fore Read More

The causes of color stains are roughly as follows: 1. Cohesion of dyesDue to the direct collision of dye molecules, they aggregate into larger dye aggregates (or dye associations). These larger dye aggregates are deposited on the fabric during the dyeing process, causing color stains.In the color de 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.
