Examples
Embodiment 1
[0059] After 12μm polyurethane thermoplastic resin film and 190g / m2 gram weight polyester polyester four-sided stretch knitted fabric are laminated with reactive hot melt polyurethane glue, the glue weight is 6g / m2 and the production line speed is 30m / min, the laminated product is subjected to thermal post-treatment (hot pressing roll method) on-line at a temperature of 100°C, a pressure of 1.0 MPa, and cooling and winding. Then the glue is matured. The surface is smooth, the fabric is not curled toward the film surface, the softness ISO 17235-2002 test result is 3.4, the peel force GB8808-1988 test result is 6.0N / 15cm, and the softness test result of the laminated product without online thermal post-treatment It is 2.9, the peel force GB8808-1988 test result average is 4.5N / 15cm, and the appearance is curled.
Embodiment 2
[0061] The 5μm polyetherester thermoplastic resin film and 40g / m2 polyolefin PP non-woven fabric are sprayed and bonded with SIS type hot melt adhesive. The glue weight is 0.8g / m2 and the production line speed is 100m / min. The product undergoes online thermal post-treatment (hot press roll method), temperature 100 ℃, 1.0 MPa pressure, cooling and winding. The obtained surface is smooth, the non-woven fabric is not curled to the film surface, the softness ISO 17235-2002 test result is 6.2, the peel force JIS L1096 test result is 1.2N / 15cm, and the softness test of the laminated product without online thermal post-treatment The result is 5.0, and the average value of the peel force GB8808-1988 test result is 0.9N / 15cm.
Embodiment 3
[0063] The film surface of the laminated product prepared in Example 2 is sprayed and bonded with a 20g / m2 polyolefin PP non-woven fabric using SIS type hot melt adhesive. The glue weight is 1g / m2 and the production line speed is 100m. / min, the laminated product is subjected to online thermal post-treatment (hot pressing roll method) at a temperature of 100°C, a pressure of 1.0 MPa, and cooling and winding. The surface is smooth, the non-woven fabric is not curled toward the film surface, and there is no glue opening. The softness ISO 17235-2002 test result is 5.2, the peel force GB8808-1988 test result is 0.8N / 15cm, and the sticker without online thermal post-treatment The softness test result of the combined product is 4.8, and the average value of the peel force GB8808-1988 test result is 0.6N / 15cm.
