  • Publication number: 20130203877
    Abstract: An object of the present invention is to inexpensively provide a method and device of producing a high viscosity polylactic acid composition, which composition is appropriate for foam molding having a high expansion ratio and is stable, and a foam molded article having a high expansion ratio formed of said high viscosity polylactic acid composition. A method of producing a polylactic acid foam molded article of the present invention which can achieve the above-described object is characterized by comprising a step of mechanically grinding a polylactic acid composition by applying a shear force, using a device equipped with an injection molding machine (B) or an extrusion molding machine (G), an orifice portion (S) and a foaming mold (P), in a foaming gas atmosphere in the orifice portion (S).

  • Publication number: 20130180169
    Abstract: A canopy sheet material for use over growing plants such as grape or berry or other fruit vines has higher water permeability in a longitudinally extending substantially center lengthwise part (33) than in lengthwise side parts (34). In use rain falling on the canopy runs down the side parts (34) and drains through the center part (33) to approximately the center of each tree or vine which keeps water away from the fruit under the less water permeable side parts (34).
