Printing and dyeing equipment to improve the color effect of printing and dyeing

The printing and dyeing equipment mainly uses its microwave equipment to heat the fiber cloth which is put into the sealed box quickly. Because the microwave heating is to use the high frequency vibration friction for heating effect, so the high temperature drying moisture of high temperature fiber cloth can increase the friction between dye and cloth, so as to increase the solid color.

Printing and dyeing equipment has been widely used in the field of drying and heating. In the field of printing and dyeing, in addition to drying operation, it can also be used in dye fixation. Such as: polyester dyeing with disperse dyes in high temperature fixation and printing fixation. Reduced energy consumption

The principle of printing and dyeing equipment is to use the solution of dip rolling dyes. After the fabric is irradiated by microwave, the dipole of polar molecules in the fiber is affected by the high frequency electric field of microwave, which leads to repeated polarization and change of arrangement direction. After repeated friction between molecules, the heating effect can be achieved, and the energy absorbed by electromagnetic wave can be quickly converted into thermal energy. At the same time, some dye molecules are induced to form high temperature under the action of microwave to achieve the effect of fast dyeing and fixation. In fact, microwave heating is to use the water induction on the fabric to generate heat, so as to increase the temperature of the fabric and the color paste printed on other surfaces. So the fabric is fixed at the end of drying.

Printing and dyeing equipment can be used not only in the dyeing of hydrophilic fibers, but also in the dyeing of hydrophobic fibers.
