Brief introduction of electrostatic flocking technology

尽管目前植绒产品繁多，设备也各不相同，植绒工艺流程大体如下:进料、上浆、植绒、预烘、焙烘、刷毛、后整理、成品。流程示意图如下：

Although there are many flocking products and different equipment, flocking process is generally as follows: feeding, sizing, flocking, pre-baking, baking, brushing, finishing, finished products. The schematic diagram of the process is as follows:

1.上浆。根据产品和底材性质,选择不同性能的粘合剂。根据不同材料和性能可以选用水性聚氨酯粘合剂或丙烯酸类粘合剂。如橡胶、塑料、钢材、玻璃、木材等为底材时，主要考虑粘接牢度。服装用而料,既要考虑耐水洗牢度,又要考虑手感柔软以及透气、透湿性能等。粘度太小植上的绒毛可能倾斜,粘度太大则妨碍植入深度,降低强度。涂层量大,会使手感差,且延长烘燥时间;涂层量少,则摩擦牢度降低。调整适当的粘度和涂层量才能确保植绒质量。

1. sizing. According to the properties of products and substrates, different properties of adhesives are selected. Waterborne polyurethane adhesives or acrylic adhesives can be selected according to different materials and properties. For example, rubber, plastics, steel, glass, wood and so on, the adhesive fastness is mainly considered. The fastness to washing and the softness of handle, air permeability and moisture permeability should be taken into account. The viscosity is too small, the fuzz on the plant may tilt, and the viscosity is too large, which will hinder the implant depth and reduce the strength. A large amount of coating will cause poor touch and prolong drying time. The coating will be less and the rubbing fastness will be reduced. The proper viscosity and coating amount can be adjusted to ensure the quality of flocking.

上浆方式目前主要采用辊筒法和刮刀法。对于植花(局部植绒),则采用圆网或平网印浆法对花纹部印浆,要求均匀、边界清晰,不能有起泡或空白点,植绒后形成植绒花纹。

The main way of sizing is roller and scraper. For flocking (local flocking), the circular screen or flat screen printing pulping method is used to print on the pattern part, which requires uniform, clear boundary, no blistering or blank spots, and flocking pattern is formed after flocking.
