The printing and dyeing industry has a special position in the textile industry, and it plays a bridging role in final products such as textiles and clothing. In the dyeing and finishing industry, the degree of matching of additives plays a pivotal role in the dyeing and finishing effect. As additives in the printing and dyeing process, textile printing and dyeing auxiliaries are mainly used in textile printing and dyeing processing, and it is of key significance in giving textiles multi-functional, multi-characteristic and diversified while being an indispensable chemical in the dyeing and finishing process.
Textile printing and dyeing auxiliaries can not only shorten the technological process, obtain high efficiency and energy saving and reduce pollution in the textile manufacturing process, but also improve the quality of textiles, especially the additives for high-grade finishing and functional finishing, which play a key role in determining the value of fabrics used in downstream industries, and give them excellent performance and high added value.
Isomeric tridecyl alcohol is a common printing and dyeing auxiliary, which is a colorless transparent liquid with high surface activity. In printing and dyeing auxiliaries, isotridecyl alcohol can interact with dyes to improve the dispersion and affinity of dyes. In addition, isotridecyl alcohol also has good emulsification and good interfacial activity, which can help the dye form a uniform film layer on the fiber surface and improve the dyeing effect.
Application of isomeric tridecyl alcohol in printing and dyeing auxiliaries
Improves dye dispersion and affinity.
Isotridecyl alcohol can be used as a color fastener to make it easier for dye molecules to form a uniform pigment distribution on the fiber. At the same time, isotridecyl alcohol can also increase the interaction force between dye pigment molecules, and improve the affinity and durability of dyes. During the dyeing process, isotridecyl alcohol can also reduce the electrostatic force between the dye molecule and the fiber, making it easier for the dye to bind to the fiber.
Improves dyeing results.
Isomeric tridecyl alcohol can help the dye form a uniform pigment distribution on the fibers by forming a film layer between the dye and the fiber surface. In addition, isotridecyl alcohol can also increase the diffusivity of the emulsifier in the printing and dyeing auxiliaries, and improve the stability and dyeing effect of the emulsifier in the dyeing process. Adding an appropriate amount of isomeric tridecyl alcohol to the staining agent can significantly improve the staining effect.
Factors influencing isotridecanol in printing and dyeing auxiliaries
The concentration in the solution
The higher the concentration of isotridecyl alcohol in printing and dyeing auxiliaries, the better its dispersion and affinity properties. In general, isomeric tridecyl alcohol is added to the printing and dyeing solution, and its concentration should be controlled at 02%~0.5%.
Dyeing process conditions
The dyeing process conditions will also affect the role of isomeric tridecyl alcohol in printing and dyeing auxiliaries. In practical applications, it is necessary to optimize the conditions according to different dyes and fiber types to ensure that the effect of isotridecyl alcohol is maximized.
In summary, isotridecanol as a textile printing and dyeing auxiliary can not only improve the dispersion and affinity of the dye, but also improve the dyeing effect. In general, the concentration of isomeric tridecyl alcohol should be controlled at 02%~0.Between 5%, the dyeing process conditions also need to be optimized for different dyes and fiber types. Through the rational use of isotridecyl alcohol, the effect of printing and dyeing auxiliaries can be effectively improved to achieve a more ideal dyeing effect.
