    摘要: According to the invention, a novel laminated fabric sheet of excellent air permeability and a method for producing the same are provided. The laminated sheet comprises a first base fabric including spun yarn and having previously been treated with a water and oil repellent, a rubber composition layer formed on the first base fabric and having a multitude of fine air passages therein and a second sheet of base fabric laminated on the rubber composition layer. The base fabric which has been treated with the water and oil repellent prevents the coated rubber composition from reaching roots of whisker fibers of the spun yarn in the base fabric and fine cells are thereby formed around the lower portion of the whisker fibers. Subsequent heating of the laminated sheet of fabrics for curing the rubber composition causes these fine cells to be inflated to form air passages through the cured rubber composition layer. The rubber composition layer includes, as its main ingredient, a product of reaction between liquid diene-polymer having at least two active hydrogen groups in the molecule and polyisocyanate.
