スチック材料を加熱軟化して圧着してもよい。In order to reduce the cohesive force of the temporary adhesive mentioned above, in the case of pressure-sensitive adhesives or hot-melt adhesives, it is necessary to heat the adhesive at a high temperature to reduce the cohesive force to the extent that it can be transferred, or to reduce the cohesive force by changing the composition. Let me do it. In the case of a soluble adhesive, the adhesive is sufficiently dissolved by a solvent to reduce its cohesive force to the extent that it can be transferred. In this way, a sheet-like plastic material having a flocked layer formed on its surface is obtained. Further, the plastic material may be pressed in a softened state to the flocked layer forming surface of the releasable base material. In this case, the plastic material may be extruded into a sheet and pressed onto the flocked layer forming surface of the releasable base material in a softened state before cooling, or the plastic material may be extruded into a sheet or molded into an appropriate shape. The plastic material may be softened by heating and then crimped.

Electrostatically flocked polyamide flock, then heated at 130'C.
A releasable base material with a flocked layer formed on the surface is obtained by drying for 15 minutes. Polypropylene is heated and softened in an extrusion molding machine and extruded into a sheet, and the sheet is placed on the flocked layer of the releasable film and pressed before solidification. After the polypropylene sheet is cooled and solidified after being suppressed, a triol is sprayed onto the paper that is the base of the releasable substrate adhered to the surface of the sheet to sufficiently wet the polyn-butyl methacrylate, thereby increasing the cohesive force. When the releasable base material is peeled off after lowering the releasable base material, the flocked layer on the releasable base material is transferred to the sheet surface together with a part of the poly n-butyl methacrylate,
The tips of the flocks constituting the flocked layer are slightly embedded from the surface of the sheet. The polypropylene sheet thus obtained has a flocked layer formed on its surface,
It can also be formed into a suitable shape by vacuum forming or the like.
