Flocking hot melt membrane and production technology thereof

Abstract

The invention discloses a flocking hot melt membrane and a production technology thereof. A hot melt adhesive layer is prepared by a TPU hot melt adhesive material, and the TPU hot melt adhesive adopts an extrusion cast film, and a hot melt adhesive layer is formed on the surface of a release paper after extrusion by an extruder. A high elastic layer is prepared by a thermoplastic polyurethane elastomer rubber material, and the thermoplastic polyurethane elastomer rubber adopts the extrusion cast film, and a high elastic layer is formed on the surface of the hot melt adhesive layer after extrusion by the extruder. A flocking layer is obtained by flocking on the surface of the high elastic layer. The invention provides the flocking hot melt membrane and the production technology thereof forflocking the high elastic layer through a flocking channel before the high elastic layer is unformed, the short floss is directly implanted into the high elastic layer, and the short floss is very firm after cooling, and no floss picking can be generated, moreover, the high elastic layer has good elasticity, and can rebound quickly after stretching and deformation, and no fault occurs.

Description

technical field [0001] The invention relates to the technical field of flocking, in particular to a flocking hot-melt film and a production process. Background technique [0002] The principle of flocking is to make use of the physical characteristics of same-sex repulsion and opposite-sex attraction, so that the fluff is negatively charged, and the object to be flocked is placed under zero potential or grounding conditions, and the fluff is attracted by the plant body by the different potential, showing The vertical shape accelerates to fly to the object surface that needs flocking, and because the plant body is coated with adhesive, the fluff is just vertically stuck on the plant body. [0003] At present, the existing flocking method is mainly to apply an adhesive on the surface of the item that needs to be flocked, and then electrostatically plant the fluff on the adhesive. This method has poor performance of the adhesive and is prone to velvet dropouts. Washable, and t...

[0003] At present, the existing flocking method is mainly to apply an adhesive on the surface of the item that needs to be flocked, and then electrostatically plant the fluff on the adhesive. This method has poor performance of the adhesive and is prone to velvet dropouts. Washable, and the traditional flocking method is prone to shedding and breakage when stretched
