Description

Technical Field

[0001] The utility model relates to the technical field of cloth detection, in particular to a device for detecting air permeability of textile cloth. Background Art

[0002] Air permeability is a physical indicator that characterizes the ability of air to penetrate a tested sample. It primarily targets porous materials with high air permeability, such as textiles, sponges, and leather. For fabrics, air permeability is related to factors such as the number and size of gaps between warp and weft yarns and fibers, warp and weft density, yarn twist, fiber properties, yarn structure, and fabric thickness.

[0003] In the existing technology, most of the air permeability testing devices for fabrics are designed to lay the fabric flat on the testing table of the testing device and then clamp it for testing. There is no device to tighten the fabric. During the testing process, the untightened fabric may wrinkle or sag due to its own elasticity or gravity, causing the gaps and channels inside the fabric to change, thereby affecting the actual flow of air through the fabric, resulting in an inability to truly reflect the air permeability of the fabric in actual applications.
