With the development of electronics, fiber, chemical industry, machinery and other industries, the quality of flocking cloth is increasingly popular, and its use is also expanding. From the original industrial cloth and decorative cloth, it has gradually developed into the field of clothing cloth. In recent years, it has developed rapidly and developed more and more new varieties. Many printing and dyeing methods have been applied to flocking cloth, such as pigment printing, gilding printing, flocking of printed cloth, and direct printing and discharge printing on flocking cloth. The use of these means enriches cloth flocking products and adds a beautiful landscape to the clothing industry.

technological process

Apply adhesive

The viscosity of the adhesive should be controlled between 15000 and 30000 cp. The viscosity is high. It is not good for the fluff to penetrate deeply into the base cloth. The fluff will fall off due to insufficient bonding strength; If the viscosity is too low, it is easy to penetrate into the base cloth. Although the fluff can penetrate into the inner layer of the adhesive, the abrasion resistance becomes higher, but the feel is hard. Therefore, the thickness of the adhesive layer should be 0.2~0.4 mm.

Flocking

The quantity of flocking wool affects the quality of flocking fabric. If the quantity of flocking wool is insufficient, the flocking density is insufficient; If the amount of hair is too much, most of the fluff is stuck to the base cloth by the adhesive, while the remaining fluff that is not stuck by the adhesive will continue to fly up and down under the effect of the electric field, affecting the indoor cleaning.

Drying and baking

The purpose of pre baking is to evaporate the organic solvent and water in the adhesive. It is generally about 80 ℃. The purpose of baking is to improve the fastness, so that the adhesive can be firmly combined with the fluff and the base cloth. The temperature is low, and the fixation fastness cannot be reached. The temperature is high, which causes the catalyst in the adhesive to precipitate acidic substances and vulcanize the substrate. The temperature is generally controlled at 150 ± 5 ℃.

Cleaning

The purpose of cleaning is to recycle the floating brush without adhesive on the flocking fabric.
