1 foam printing features. a. The density of the foam does not exceed 0.7 g/ml; the viscosity is in the range of 20 to 200 centipoise. b. The printed fabric is bright in color and soft to the touch. 2 foam printing example. b. Foam printing: Using this printing paste, it is printed on a cotton cloth through a rotary screen, dried, and heat-treated at 150°C for 3 minutes. As a result, the printed blue print fabric has a bright color, a soft hand, and is significantly resistant to washing and dry cleaning.

An aqueous solution containing a thickener (0.1 to 5% by weight), a binder (1 to 10% by weight), and a surfactant (l to 5% by weight) is insoluble The mixture is stirred in the presence of inert gas in water to form a foam which is 1.5 to 3 times the volume of the original aqueous solution, and then mixed with the paint to prepare a foam printing paste. Fabric printing with this foam printing paste is called foam printing.
c. Printing paste stability is good.
d. Especially suitable for rotary screen printing.
The adjuster, binder, sodium alginate, and water were mixed with each Other, and then aqueous ammonia was added to produce a uniform, foam-free solution. Next, sodium lauryl sulfate and dodecyl (alk) were added and the stirring was continued to form a foam. The specific product is 2 times the original solution, and the concentration and viscosity are within the specified range. This foam was then mixed with the suspension of Aquarine Blue 3GW to make a print paste.
