The present invention provides a substrate having a unidirectional water transport property, the substrate comprised of a fluid permeable structure and including: an inner side surface; and an outer side surface having a higher absorbent capacity than the inner side surface, wherein the inner side surface has a hydrophobic surface layer extending continuously over at least one section thereof, the hydrophobic surface layer having a predetermined thickness which, in use, produces a substantial hydrophobic property to contacting water, whilst allowing for water contacting the inner side surface of the substrate to wick through the hydrophobic surface layer into the substrate; and wherein the substrate is respectively comprised of hydrophobic channels and hydrophilic channels which respectively extend between the inner side surface and the outer side surface.

A curl straightening method applied upon printing on a spread medium in a printing step, the method being provided with a first spreading step of spreading the medium fed out from a medium roll between a feeding step of feeding the medium from the medium roll in which the medium made of a textile fabric and having a predetermined width is wound on a roll core, and the printing step of printing on the medium fed out from the medium roll, and in the first spreading step, spreading of the medium is performed in a state where the medium fed out from the medium roll is stretched on an outer circumference of a first spreader roller rotating about a pivotal axis parallel to a pivotal axis of the medium roll, and the medium has its surface side with a curl stretched on the outer circumference of the first spreader roller.

A rotary screen transfer printing machine and a control system thereof. The rotary screen transfer printing machine having a feeding unit, a printing unit, a drying unit, and a receiving unit; the printing unit has at least one rotary screen transfer printing assembly and a guide belt assembly; each rotary screen transfer printing assembly has a rotary screen plate roller and a transfer roller; the rotary screen plate roller is close to the transfer roller; the transfer roller is seamlessly coated with rubber or a resin having good affinity for a water-based ink. A control system includes: a motion controller; a conveying synchronization module, used for controlling the feeding unit, the printing unit, the drying unit, and the receiving unit to synchronize the conveying speeds of the four units; and a rotary screen transfer printing synchronization module.

A roll-to-roll printing process for large scale manufacturing of nanosensor systems for sensing pathophysiological signals is disclosed. The roll-to-roll manufacturing process may include three processes to improve the throughput and to reduce the cost in manufacturing: fabrication of textile based nanosensors, printing conductive tracks, and integration of electronics. The wireless nanosensor systems can be used in different monitoring applications. The fabric sheet printed and integrated with the customized components can be used in a variety of different applications. The electronics in the nanosensor systems connect to remote severs through adhoc networks or cloud networks with standard communication protocols or non-standard customized protocols for remote health monitoring.

A pad printing machine is arranged for enabling the transfer and application of multiple layers of ink from an ink source both into and onto an ink receiving member. The pad printing machine comprises a depth enhanced ink well (about 0.0015 to about 0.0035 inches deep) for peripherally enclosing an absorbable pattern of ink, a vertically and horizontally displaceable temperature controlled ink transfer print pad, and a temperature controlled printable item support print fixture for supporting an ink receiving printable item member, to enable multiple layers of ink to be simultaneously transferred after pickup by the print pad as one layer, and inversely and simultaneously applied as multiple layers into and onto the ink receiving printable item member on the support print fixture.
