① Cotton fiber burns when it encounters a fire. It burns quickly and produces a yellow flame with an odor; it has a slight off-white smoke, which can continue to burn after leaving the fire. After the flame is blown out, there are still sparks that continue to burn, but the burning time is not long; Read More
1. The influence of solvent and mediumThe absorption wavelength of the dye solution changes with the polarity of the solvent. When the dye is dissolved in a polar solvent, the polarity of the dye increases as the polarity of the solvent increases, so that the excitation energy is reduced, the absorp Read More
What is the role of fixing agent in fabric fixing?Fixing agent can be used to improve the color fastness of dyes on fabrics. It can form insoluble colored substances with dyes on the fabric to improve the washing and perspiration fastness of the color, and sometimes the light fastness. In the catego Read More
MSC Mediterranean Shipping Company announced that the following new freight rates will be released from February 1, 2021 until further notice, but not later than February 28, 2021. Unless otherwise stated, all prices are in U.S. dollars. Read More
1 Sampling and pretreatment The key steps to identify the types of dyes on cellulose fibers are sampling and sample pretreatment. When taking the sample, the part of the same dye should be taken. If the sample contains several shades, each shade should be taken. If fiber identification is required, Read More
When it comes to the detection of fluorescent whitening agents, the first thing everyone thinks of is to use a currency detector to irradiate it, which is the ultraviolet lamp method. Since the principle of the fluorescent whitening agent is that the blue light excited by the ultraviolet light neutr Read More

Fixing principle of fixing agentThe current fixing agents can be roughly divided into cationic polymer type fixing agents, resin type fixing agents (containing formaldehyde resin type fixing agents, containing polyamine resin type fixing agents), and crosslinking reaction type fixing agents.The fixi Read More
A Maersk executive said that in the reality of strong demand, there is almost no excess capacity in container ships, and the congested supply chain can hardly be alleviated. Maersk Line’s parent company AP Moller-Maersk A/S Latin America and the Caribbean Senior Vice President Fan Chuyan Robbert van Read More
Let us first understand the fluorescent brightener. It is a type of fluorescent dye, which belongs to a separate category in the Colour Index (C.I.). The molecular structure of fluorescent whitening agent is mainly composed of a continuous conjugated system containing an aromatic ring and one or mor Read More
