Pure cotton fiber has the advantages of good moisture absorption, alkali resistance and strong heat resistance, but the fabric finish, uniformity, feel and drape are not as good as rayon;Rayon fiber has good dyeability, high brightness and color fastness, comfortable to wear, moisture absorption sim
There are two main methods of fabric printing and dyeing, one is traditional paint printing and the other is reactive printing and dyeing as opposed to paint printing and dyeing.Reactive printing and dyeing means that the active gene of the dye is combined with fiber molecules under certain conditio
In addition to excellent design, the choice of fabric is also an important factor for good clothing. An excellent design concept needs to have matching fabrics to express it perfectly.Therefore, it is their daily needs for fashion designers to pay attention to fabrics and their fashion trends.As an
The influence of disperse dyeing The thermal migration of disperse dyes is not the redistribution of dyes in the two phases of fiber and surface solvent under dry heat conditions, but its inherent physical characteristics, which also cause the color fastness and shade variation of polyester-contain
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
Causes of scattered dyeing spots and spots There are two kinds of color spots and spots produced by the high temperature and high pressure dyeing machine when dyeing polyester knitted fabrics:1. The color spots and spots caused by the condensation of dyes can be repaired with a repair agent or strip
The so-called tarification of dyes refers to the process in which dye particles and surfactants agglomerate into coal tar-like substances under high temperature conditions.There are usually the following 4 factors that cause dye tarizationPoor pretreatment and insufficient purification. The oil (lub
The maximum working temperature of this kind of proofing machine is 130℃, the heating speed can be adjusted, and two electric heating tubes are used as the heat source. Up to 12 dye cups can be placed, and the hook with the sample is moved up and down by the linkage device to complete the proofing p
As the global economy recovers from the epidemic, the Turkish textile industry hopes to open a new era of cooperation with international companies and brands, with production capacity exceeding US$100 billion. Turkey is the fifth largest textile supplier in the world and is expected to export textil
Key points of chemical material operation1. Check the accuracy of the prepared dyes and chemicals according to the prescription list. When disperse dyes are used to make materials, generally use cold water to beat them and mix them evenly (stirring with a mixer for about 20-30 minutes), and then dil
1. When dyeing, close the machine cover before heating up, and observe the running condition of the grey cloth in the machine from the glass sight hole at any time, and check whether there are any abnormal sounds and phenomena in the machine parts.2. When the temperature is 50～60℃, the disperse dye
Nylon 6 is a type of polymer material with characteristic structure amide bonds on the main chain of macromolecules, and its dyeing performance is similar to wool. It has excellent strength, abrasion resistance, soft hand feeling, light texture and other good wearing properties, and it occupies an i
