HEAT-BONDABLE POLYURETHANE FILM |
摘要 |
The object of the present invention is to provide a polyurethane film having heat adhesion and further having high stress retention and excellent elastic functions, and the polyurethane film of the present invention is a heat adherent polyurethane film wherein the thermal adhesion peeling stress indicated by a maximum stress when separating a film from a cotton fabric after hot-pressing the film to the cotton fabric at a temperature of 130°C under a pressure of 4 bar for 25 seconds is 5.88 N/cm or more and the stress retention at an elongation percentage of 200% indicated by a ratio of a stress (f R ) in recovery to a stress (f S ) in stretching at an elongation percentage of 200% in an S-S curve drawn when the film is stretched to an elongation percentage of 300% and then recovered is 40% or more. |
