A composite sheet product comprising:
- a skin sheet including ultrafine fibers having an average monofilament diameter of 0.1 to 10 μm and an elastomer, and a woven or knitted fabric that are laminated on each other, wherein the skin sheet and the woven or knitted fabric are laminated on each other with a resin layer containing a flame retardant and an adhesive layer interposed therebetween.
A method of manufacturing a composite sheet product, the method comprising steps 1 to 3:
- 1. adding a resin containing a flame retardant to a skin sheet including ultrafine fibers having an average monofilament diameter of 0.1 to 10 μm and an elastomer;
- 2. imparting nap or unevenness to at least one surface of a woven or knitted fabric;
- and
- 3. sticking, with an adhesive, a surface of the skin sheet obtained in step 1, the surface having the resin containing the flame retardant, to the surface of the woven or knitted fabric obtained in step 2, the surface having nap or unevenness.
