What Is Printing Paste And Its Characteristics

Printing paste color pulp refers to the mixing ratio of different proportion of dye water with printed paste (when adding printed color pulp, generally dissolved in water or fully bloated and dispersed in water). Purch.

Polychism

Dyes or pigments (coatings)

Additives (fixing agent, hygroscopic agent, dispersion agent, solvent, muffin, etc.)

Original paste (paste and water consisting of paste and water)

The requirements of printed projects on printed colored pulp

(1) The mixed state of each component of the color slurry is uniform; no impurities, no large particles, no pieces;

(2), have a certain amount of wetness, adhesion, and internal agglomeration;

(3) The color paste has a certain flow of degeneration; it is easy to form a film, and it is elastic;

(4), with a high upper dyeing rate and giving color;

(5), have good printing uniformity and appropriate printing;

(6) The easy removal of the auxiliary substances;

(7) Good stability;

(8) The solid content is as low as possible.

According to the requirements of the printed color, we compare the composition of the color pulp and the composition of the dye solution. The composition of the dye solution is mainly a solution of the dye (or pigment) and the auxiliary water solution or other liquid (critical carbon dioxide). The color paste is more primitive with it. Therefore, the role of the original paste in the color pulp can be imagined. The performance of the color pulp mainly depends on the performance of the paste, and the practice has proved that the same is true.

Ideal paste

(1) High paste rate; small dosage and small pollution;

(2) Given high color: not chemically combined with the dye, low affinity for dyes, and do not change dye color light;

(3) It has good wetness and water hugging, stability; the contour contour is clear without seepage;

(4) The compatibility of the dye and the auxiliary agent is good, the dispersability is good, and it has good storage stability; it provides a good color -solid environment for the combination of dyes or pigments and fabrics.

(5) It has a certain flowing performance (moderate viscosity), that is, there must be a certain viscosity, tactile, plastic elasticity;

(6) It has a certain stickiness to the fabric;

(7) Fast conjunctiva, soft, not cracking;

(8) Easy to wash.
