The flocking printing usually referred to means a cotton-like technique such as cotton fabric or carpet, which does not have the print feeling. Also known as fluff imprinting or wool processing, it is a printing method that imparts a textile-like effect on paper or on a fabric.
For example, there is a cloth-made doll that is sewed by itself and has a pattern printed on the cloth surface and a cut line. The colored parts are planted with fluff, which are cut and cut according to the cutting line to form a cloth doll.
Flocky is the meaning of sticking the swarf. The short fibers of about 0.2mm to 1.5mm are implanted on the fabric or paper surface by static electricity to obtain a three-dimensional print.
The method of production is to print the common pattern first by offset printing, then to print the paste on the part intended to be flocked by means of screen printing, apply a negative charge, and apply rayon on the positively charged plate. Short fibers or dust made of nylon, wool, or gold-silver powder, due to the short distance between the positive and negative electrodes, utilize the electrostatic principle of attraction between the positive and negative electrodes, so that the fibers are adsorbed on the brushed pattern and stand upright. .
If the flocked material is a three-dimensional object, glue can be sprayed on it with a spray gun and the fiber can be stood up by means of static electricity.
The difficulty lies in the strength
The materials that can be used for flocking are paper, plastic products, leather, wood products, ceramics, metal products, etc. The colors of fibers used for flocking are various colors other than gold and silver.
In addition to the above-mentioned fabric dolls, electrostatic flocking is currently accompanied by linings of jewel boxes, coasters, albums for the blind, interiors of automobiles, and the like. Although it looks like it is affixed with fabrics, In fact, there are many occasions where printing is used.
Because electrostatic flocking basically relies on adhesive to adhere short fibers, if the viscosity of the paste is not enough, the strength of the flocking will not be strong enough, and it will fall off due to friction. In view of this, the fine pattern of the line is not suitable. Electrostatic flocking printing method
