100% polyester reinforced material for the manufacture of a laminated film to form an applicator for holding a pest control agent process for the manufacture of a laminated film, reinforced laminated film and applicator containing a fumigating agent

摘要

The invent comprises a material made of a gas and water vapour permeable non-woven, water-free, which differs in that it has one single basic component, that is, 100% polyester, with fibers having a softening or melting point of 220 to 280 degrees Centigrade and a paste with thermoplastic properties of the same component (polyester) with a melting or softening point of 90 to 150 degrees Centigrade; process used for manufacturing the laminated film starts from a grid (1), or reinforcement, woof fibers (2) and thermoplastic paste (3) with the same original base, while the laminated film (4) is obtained through continuous process of physical bonding, whereby the warp fibers of the grid (1) are stretched and covered by an upper and lower coating of a mixture of small woof fibers (2) with thermoplastic paste (3); bonding is achieved by pressure and heat (thermobonding), in a series of metallic cylinders and presses; resulting applicator for pesticide or fumigating compounds, is a gas and water vapour permeable non-woven, water-free, featuring a single component, namely polyester.
