Abstract
A non-contact fiber permeability measurement system includes a mold device, a fluid supplying device, a capacitance detecting device and a permeability converting device. The mold device includes an upper plate, a lower plate and a fluid inlet. The lower plate is parallel to and disposed below the upper plate for forming an accommodating space disposing a measured fibrous fabric insulated against the upper plate and the lower plate. The fluid inlet is disposed through the upper plate. The fluid supplying device is connected to the mold device and for providing a fluid perfused from the fluid inlet into the accommodating space. The capacitance detecting device is electrically connected to the upper plate and the lower plate. The permeability converting device is electrically connected to the capacitance detecting device and for receiving the capacitance detected via the capacitance detecting device to convert the capacitance to a permeability.
