Mesh body

Abstract

A mesh body made of polyethylene terephthalate (PET) having good orientation and having relatively high heat resistance is provided. Each of a split web 1 (longitudinal web) and a slit web 6 (lateral web) has a three-layer structure including a layer (main layer) made of a first thermoplastic resin and bonding layers made of a second thermoplastic resin provided on the respective surfaces of the main layer. The second thermoplastic resin has a heat-sealing property at a temperature lower than a melting point of the first thermoplastic resin. A nonwoven fabric 8 is formed by laminating crosswise a longitudinal web and a lateral web via their bonding layers so that orientation axes of the webs cross perpendicularly to each other. The first thermoplastic resin is PET. The second thermoplastic resin is an amorphous PET copolymer. Before laminating crosswise the webs, their surfaces (bonding layers) are applied with a corona treatment.

1 . A mesh body comprising:
 uniaxially oriented bodies each including a main layer made of a first thermoplastic resin and a bonding layer provided on at least one surface of the main layer and made of a second thermoplastic resin having a heat-sealing property at a temperature lower than a melting point of the first thermoplastic resin, the uniaxially oriented bodies being laminated crosswise or woven via the bonding layer so that their orientation axes cross each other to form the mesh body,   wherein the first thermoplastic resin is polyethylene terephthalate, and   wherein the second thermoplastic resin is an amorphous polyethylene terephthalate copolymer.   
     
     
         2 . The mesh body according to  claim 1 , wherein the uniaxially oriented body includes the main layer and the bonding layer provided on each side of the main layer. 
     
     
         3 . The mesh body according to  claim 1 , wherein the bonding layer is applied with a corona treatment prior to the crosswise lamination or the weaving.
