A method for manufacturing a three-dimensional fabric and a three-dimensional fabric using the same is provided. The hyperechogenic particulate material can be covered by a polymeric coating or embedded in a polymeric material to provide a hyperechogenic layer. A linear displacement sensor is operatively connected to the support member and the liquid dispensing head so that displacement of the liquid dispensing head relative to the support member is sensed upon contact of the dispensing head with the substrate. Thereafter, the frequency of the output voltage is modified to a predetermined level. Not only it is possible to downsize the boot, but also it is possible to inhibit abnormal noises from generating when water intervenes in-between. Said halloysite nanotubes are incorporated with active agents such as antibacterial agents preferably of natural type for providing antibacterial, barrier and ethylene scavenging properties.
