Latest News and Updates on Textile Auxiliaries and Dyes

When polyester-cotton blended fabrics are dyed in hot melt, the color matching dyes must also have the same properties as the monochromatic dyes. The melting temperature and time should be compatible with the fixing characteristics of the dye to ensure the highest color yield. Each single color dye Read More

Disperse dyes are poured into water and then dispersed into fine particles. The particle size distribution is expanded according to the binomial formula, with an average value of 0.5 to 1 micron. The particle size of high-quality commercial dyes is very close, and there is a high percentage, which c Read More

What matters should be paid attention to when acid dyes are fixed?Nowadays, acid dyes have been widely used in the dyeing of fabrics and are often used by people. However, the dyes usually have poor color fastness. Therefore, some users are fixing the dyes to meet the standard, but we need to pay at Read More

Under various soft processing conditions, the working fluid should be very stable. 2. Does not reduce the whiteness and color fastness of fibers or fabrics. 3. The softened fiber or fabric is not easy to be discolored by heat, and there should be no changes in color, feel, or odor during storage. 4. If the softener is emulsion, its emulsion stability is better. 5. According to different processing requirements, it can have proper water absorption or water repellency, anti-static properties and other properties (should be selected according to the different requirements of the fabric). It is resistant to washing or dry cleaning. 6. There is no adverse effect after human skin contact.c is not easy to be discolored by heat, and there should be no changes in color, feel, or odor during storage.4. Read More

This type of softener is an emulsion or microemulsion of polysiloxane and its derivatives, which can make the fabric have a good soft and smooth feel. The products include emulsion polymerization, polymer silicone oil emulsification, modification, compounding and other production techniques, which h Read More

Causes of dye fading under the sunWhen a dye molecule absorbs the energy of a photon, it will cause the outer valence electron of the molecule to transition from the ground state to the excited state. According to different structures, the dye molecules can have different excitation processes under Read More

For dyeing with reactive dyes, the choice of the three primary colors of dyes must be paid attention to by dyeing workers. Among them, the ratio shift value (Rf) of the dye is a very important parameter. The Rf value represents the affinity of the dye. During dyeing, it determines the instantaneous Read More

According to the latest report from the World Wide Web, India has set a new global record of new crown diagnoses for 4 consecutive days, with an average of 1 death every 4 minutes. If it is said that only using words like "hell on earth" to describe the current situation in India cannot give people Read More

The molecular formula is CH3[Si(cH3)2]nSi(CH3)3. The average molecular weight is 5000-100000. Depending on Read More

What is leveling agents and its application? Most leveling agents are water-soluble surfactants. According to the effect of leveling agents on the diffusion and aggregation of dyes, they are mainly divided into two types: fibrophilic leveling agents and dye-philic leveling agents.Uniform dyeing: Whe Read More
