Water-colored functional white-printed fabric is a fabric that can be written or painted with a pen or brush after printing a special milky white printing paste on the fabric. When writing or painting, it can produce colored text or pattern. After the moisture on the fabric is evaporated, the fabric is milky white without text and pattern, that is, it can continue to be written or painted, and it can be recycled and reused. It is the best environmentally friendly product because it is loved by the painter and the painter. Writing with tap water is colorless, tasteless, and non-polluting.
Composition of color-changing function printing paste
The color paste of the water-colored functional white-printed fabric is composed of two parts: ground printing paste and white printing paste: the ground printing paste can be made from general paint printing paste, fluorescent printing paste, reactive dye printing paste and dispersion. Dye printing paste, etc., but requires the color paste to be bright and beautiful. Covering white printing paste is composed of special polymer materials. To obtain excellent covering effect and writing effect, the material must be screened and tested. The final printing paste must control its whiteness, viscosity and scratch resistance. , rheology, PVI value, film formation, film fastness and slurry stability.
Water color printing function printing process
The water-changing function milk-white printing fabric is completed by the ground color printing and the white printing secondary printing process. The composition of the secondary printing color paste is completely different, but it has good mutual performance and can maintain the secondary printing color paste. The color fastness is good.
Fabric printing paste - drying - baking - printing cover white pulp - drying - baking.
Production points of water-changing functional printing
(1) Water-color-changing function The milk-white printed fabric is printed twice, so it is necessary to pay attention to the uniform color when printing in the ground color.
Prevents ills such as bottoming and unevenness, and affects the covering effect of covering white pulp.
(2) Water-discoloring function The characteristic of white-printed fabric is that it must be sensitive when writing with a pen or a brush. That is, when writing, it can be displayed when writing, and it must have a pen effect. If there is a late display phenomenon, For poor sensitivity, the writing effect is poor, which is the key to the function of water color change, and must be strictly checked during production.
(3) The color fastness of the water-colored functional white-printed fabric is mainly to evaluate its rubbing fastness and crease fastness, and does not require washing fastness. The product is characterized by repeated writing, repeated evaporation and drying, which should be It can be used innumerable times, as long as the milky white printing paste is intact, the writing effect can be kept unchanged.
