The purpose of this study is to develop new effective air supply devices, taking into account the current level of development of science and technology and the emergence of modern high-tech materials. These include microperforated fabric ducts made of a polymer composite material. The holes in such ducts are cut with a laser. The results of studying the geometric characteristics of micro holes in a textile air duct section using an optical microscope are presented. It was found that the area of the holes varies in the range from 39629 μm2 to 50955 μm2. The average value of the area of micro holes is S = 47718 µm2, which corresponds to a diameter of d = 242 µm (0.24 mm), and the diameter declared by the manufacturer is 0.2 mm. The results obtained make it possible to determine the resistance of a microperforated fabric air duct.
