MANUFACTURING METHOD OF THE FLOODING PREVENTION SHEET FOR THE ENGINEERING WORKS KEEPING THE HIGH-END ADHESION

摘要

PURPOSE: A manufacturing method of the flooding prevention sheet is provided to reduce soil-loss of levee and to maximize a covering capability by preparing a structure to integrate spaces between fibers, which naturally prepares space for securing a tenacity inside of the flooding prevention sheet for the engineering works, to work as the product for levee or the river embankment cover. ;CONSTITUTION: As to the manufacturing method of the flooding prevention sheet for the engineering works of three stories configuration, which are a white non-woven fabric(1003), and drag net phase fabrics and a liner non-woven fabric(1001), the manufacturing method of the flooding prevention sheet(1000) for the engineering works of three stories configuration obtains a white non-woven fabric by molding a non-woven fabric of a polyolefin fused or a polyvinyl chloride to a Vacuum forming roll. According to a process of welding the liner non-woven fabric in the gray back non-woven fabric, the strengthening tensile covering is offered. The heat of one shaping cavity of the Vacuum forming roll is added. In order to have a rectangular opening before welding a rear side of the liner non-woven fabric in the white non-woven fabric the two-for-one twisting drag net phase fabrics woven compartment is welded between the liner non-woven fabric and white non-woven fabric overlapping. By using an opening shape of the drag net phase fabrics(1005), the non-woven fabric is unified. Products with high diffuse transmittance of the light ray are manufactured.;COPYRIGHT KIPO 2011
