Title: Moss plant-carrying body for greening
Inventor: NOGUCHI KAZUHIRO
IPC: C08L101/16
Filed: 2002-07-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a moss plant-carrying body for greening preferably used for greening the rooftop and the wall surface and the slope of a building.  <P>SOLUTION: In the moss plant-carrying body for greening, a gametophyte of the moss is fixed to a sheet for carrying containing polyvinyl alcohol. As a result, falling off of the gametophyte of the moss from the moss plant-carrying body in an initial stage of the configuration which is liable to fall off is prevented by adhesiveness which the polyvinyl alcohol has and the moss plant is readily attached to a material to be greened, e.g. the rooftop surface, the wall surface or the slope by gradual decomposition, elution and loss of the polyvinyl alcohol by rainfall. The polyvinyl alcohol is free from occurrence of an alkaline substance and inhibition of growth of the moss plant, because the polyvinyl alcohol is neutral even after decomposition.  <P>COPYRIGHT: (C)2004,JPO

The warp 7 of the net 5 absorbs the quick-drying adhesive by capillary phenomenon. When the dropped adhesive is diffused to some extent, the diffusion is stopped by the absorptive action of the warps 7. Thus, the net is rapidly bonded so as to obtain finish with excellent appearance.  <P>COPYRIGHT: (C)2004,JPO
