Relative information about Printing and Dyeing Shang hai Exhibition.
Description
Dye show is held in Shanghai. And do you know the composition of inject ink ? But no matter what type of inject ink is, its basic composition is colorant, the dispersion medium (water, organic solvents), anti bacteria agent, pH regulator, humectant and so on, and forPigment inks include dispersant and binder etc.
1．Colorant
Colorants used in textile printing are divided into dyes pigments and the mixture ink of dyes and pigments. Nowadays, the developed printing inject ink are mainly reactive dyes, acid dyes and disperse dyes.
2．Anti bacteria agent
Anti bacteria agentcan prevent the ink turning into mildew and refrain from mold block because of mildew ink.
3．PH regulator
On the one hand, PH regulatoris to prevent the hydrolysis of dyes to ensure the stability of the dye. On the other hand, PH regulator is to make the ink neutral to avoid corrosion of the nozzle and system of inkjet printing machine.Sublimation ink Therefore, PH value about 8 is necessary for the composition of ink.
4．Surface active agent
There are two functions of surface active agent. One is to control the surface tension of ink to meet the demand of digital inkjet printing machine. The other is to help dissolve the dyes to improve the stability of dye solution. Generally, surface active agent consists of Gan alcohol or naphthalene sulfonic acid substances.
5．Humectant
The adjunction of humectantcan not only play the role of preventing nozzle block because of fast dry ink which generates inkjet obstacle, but also adjust the ink diffusion and penetration on the fabric.
6．Dispersant
Dispersantis especially used in pigment inkjet printing inkwhich is used for pigment dispersion. Commonly used dispersants are polystyrene maleic anhydride, polyacrylic acid and so on.
7．resin
For pigment inkjetPigment ink, because the pigments have no affinity to textile fiber, it is necessary to make use of the function of resin which adhere to color the fabric. The commonly usedpolyacrylic acid resinadhesive is intoxicated, waterborne polyurethane and UV curing adhesive.
Therefore, the composition of ink probably includes seven components. With the discovery and synthesis of new materials, environmentally supplies with lower consumption will replace the old one to optimize production and utilization.
