[comparative example 1] is except using the first cloth and silk that does not carry out the calking processing, and be the same with embodiment, obtains the laminated body of comparative example 1.Number, the particle diameter of the point of resin (b) and resin (c) is the value identical with embodiment 1, and between the first cloth and silk and water proofing property film, the occupation rate of resin (b) is 50%.(certainly, the occupation rate of resin (a) is 0%).In addition, between the second cloth and silk and water proofing property film, the occupation rate of resin (c) is 50%.
Coil bending does not occur in the laminated body of [evaluation of laminated body] embodiment 1 and embodiment 2 fully on the first cloth and silk, still, on the laminated body of comparative example 1, at the first cloth and silk coil bending occurs, and really becomes problem as goods.
Flexibility, the feel of embodiment 1 and comparative example 1 laminated body separately are substantially the same.The flexibility of the laminated body of embodiment 2 is no problem in practical, still, poor than embodiment 1 and comparative example 1.
As the close-burning evaluation between each layer of laminated body, as benchmark, measure the peel strength between peel strength, the second cloth and silk and the water proofing property film between the first cloth and silk and the water proofing property film with JIS L10867.19.1 " peel strength ".Peel strength between the first cloth and silk and the water proofing property film is 350gf/cm in first embodiment, is 300gf/cm in comparative example 1.Therefore, can find out, resin (a) helps the bonding of the first cloth and silk and water proofing property film.In addition, in embodiment 2, be 450gf/cm.
For the second cloth and silk of embodiment 1 and embodiment 2 and comparative example 1 and the peel strength between the water proofing property film, the material damage of water proofing property film can not be measured, and still, can judge to have enough cohesive forces.
In addition, after the heating pressurized treatments of the first bonding operation, can not correctly measure the fusing point of resin (a), can confirm that resin (a) is partly crosslinked.In addition, the urethanes that uses as resin (b), resin (c) is hot-melt adhesive, after laminated body is just made, fusing point does not have large variation, still, and after laminated body is made through 1 week, can correctly confirm fusing point, can confirm to occur crosslinked.This can think because employed urethanes is that hot-melt adhesive is the hot-melt adhesive of moisture-curable type.
