- 摘要：
PROBLEM TO BE SOLVED: To provide a heat retaining sheet for greenhouse, improving heat retaining effect in greenhouse so as to reduce fuel consumption required for heating, and capable of suppressing dewfall in greenhouse and damage of crops.
SOLUTION: This heat retaining sheet is a laminated sheet 11 which is obtained by laminating by an extruding laminating method, low density polyethylene layers 13 and 13 on both sides of a nonwoven fabric 12 made of a fibrous material derived from regenerated cellulose. The basis weight of the nonwoven fabric is 20-60g/m
2 , and an infrared spectroscopy absorption rate of a wavelength of 800-2600 nm in the laminated sheet is &ge15%. A reinforcing layer 20 of a synthetic resin woven fabric 21 is stuck to one side of the laminated sheet.COPYRIGHT: (C)2010,JPO&INPIT
