Abstract
Official abstract text for this publication.
In a nonwoven fabric, uniaxially oriented bodies each including a thermoplastic resin layer and first and second adhesive layers respectively stacked on both surfaces of the thermoplastic resin layer and having melting points lower than that of a thermoplastic resin constituting the thermoplastic resin layer are warp-weft laminated with the first or second adhesive layer interposed between the uniaxially oriented bodies in such a manner that orientation axes thereof intersect each other. The nonwoven fabric has a mass per unit area of 5 to 13 g/m 2 , a layer composition ratio of the first adhesive layer, the thermoplastic resin layer, and the second adhesive layer in each of the uniaxially oriented bodies is 20/60/20 to 30/40/30, and an average value of bending resistances by a cantilever method is less than or equal to 50 mm.
First claim
Opening claim text (preview).
1 . A nonwoven fabric that is a reticular nonwoven fabric in which uniaxially oriented bodies each including a thermoplastic resin layer and first and second adhesive layers stacked on both surfaces of the thermoplastic resin layer and having melting points lower than that of a thermoplastic resin constituting the thermoplastic resin layer are warp-weft laminated with the first or second adhesive layer interposed between the uniaxially oriented bodies in such a manner that orientation axes of the uniaxially oriented bodies intersect each other, wherein the nonwoven fabric has a mass per unit area of 5 to 13 g/m 2 , a layer composition ratio of the first adhesive layer, the thermoplastic resin layer, and the second adhesive layer in each of the uniaxially oriented bodies is 20/60/20 to 30/40/30, and an average value of bending resistances by a cantilever method in a longitudinal direction and a transverse direction of the nonwoven fabric is less than or equal to 50 mm. 2 . The nonwoven fabric of claim 1 , wherein the thermoplastic resin layer includes high-density polyethylene, and each of the first and second adhesive layers includes low-density polyethylene. 3 . A reinforcing laminate, wherein the nonwoven fabric of claim 1 is stacked on a reinforcing target material and is used as a strengthening material. 4 . A reinforcing laminate, wherein the nonwoven fabric of claim 2 is stacked on a reinforcing target material and is used as a strengthening material.
