Introduction Of Electrostatic Flocking
Electrostatic flocking is widely used and popular in industrially developed countries, such as the United States, Italy, Germany and Japan, because of its unique decorative effect of suede
and embroidery, as well as its simple process, low cost and strong adaptability.In recent years, a variety of electrostatic flocking products have also been developed in China.Electrostatic flocking has a wide range of applications, such as the use of flocking machine can process different fabrics, different grades of textile fabrics. Colored velvet paper made of various kinds of fluff can be used for art decoration, display boards, window, trademarks, etc. The craft painting style of various design pictures has a unique style.
Machining Method
Flocking processing can be divided into descending method, ascending method, transverse flying method and upward and downward flying method according to the different direction of flying villus. More than 80% of domestic flocking processing equipment adopts the descending method, so the descending method is taken as an example to explain its working principle.The upper plate is a plate type metal mesh frame, and the lower plate is a metal plate bracket, which is covered with a screen printed with adhesive to be flocking base cloth. The upper and lower two plates are respectively connected with wires to the positive and negative output ends of the high voltage electrostatic generator. The fluff in the hopper falls on the negative pole of the metal mesh due to the rotation of the fuzzy-supplying shaft. The villi are charged by contact with the negative electrode during the descent, causing them to partially align in the direction of the electric field.The upper plate is a plate type metal mesh frame, and the lower plate is a metal plate bracket, which is covered with a screen printed with adhesive to be flocking base cloth.

The fluff in the hopper falls on the negative pole of the metal mesh due to the rotation of the fuzzy-supplying shaft. The villi are charged by contact with the negative electrode during the descent, causing them to partially align in the direction of the electric field.When the villi contact the negative electrode, conductive current will be generated in the fiber because the conductivity of the electrode is higher than that of the villi, and the villi will generate negative static charge, which makes the villi have a great degree of elongation and flight in the electric field. The villi will fall vertically to the base cloth with adhesive pattern on the net at a high speed, forming fine suetex-text. In electrostatic flocking processing, the villi are not only charged due to contact, but also charged due to polarization effect when entering the electric field, which ensures that the villi move toward the positive plate direction, and makes the villi rotate continuously in the uniform electric field, so that the villi stand upright on the surface of the base cloth instead of lying flat on it.
