DTF digital printing white ink and production equipment thereof

The invention relates to DTF digital printing white ink and production equipment thereof, and belongs to the technical field of grinding equipment, the white ink is relatively simple in composition and low in solid content, under the normal-temperature liquid condition, a water-based DTF white pigment ink system is relatively stable, and the phenomena of particle aggregation, flocculation and composition crosslinking or layering are avoided. When a wet ink film is baked at a high temperature of 90 DEG C or above, a closed aliphatic polyisocyanate curing agent NCO group in a water-based DTF white pigment ink system is unblocked, and the water-based DTF white pigment ink system is subjected to a cross-linking reaction with resin in a lower CMYK four-color ink film layer while being subjected to self-cross-linking curing, so that the water-based DTF white pigment ink is obtained. And the color-white double-layer ink film forms a three-dimensional network cross-linked structure. The three-dimensional network cros
