  • FIG. 39A and FIG. 39B show a diagram of the front and back, respectively, of a shirt with a liquid-absorptive region which covers both the collar and chest area and extends to the side dripping points of the shirt while the abdomen region is kept liquid-repellent.
  • FIG. 42B is an image of an example fluidic network structure as applied to the waistband of the front of a pair of shorts.
  • FIG. 44 is a diagram illustrating another fluidic channel network configuration where fluid-absorptive channels cover the shorts to transport the sweat to the sides of the shorts and drip it away via the dripping points.
  • FIG. 48A is a perspective view of one embodiment of a four cornered tent with a fluidic network structure.
  • FIG. 1A is a schematic diagram of one embodiment 100 of a liquid-absorptive region 102 forming a channel 118 within a liquid-repellent region 104 of a substrate 106 .
  • the wetting contrast between these two regions will form a virtual channel 118 to confine the liquid flow inside the liquid-absorptive region 102 , while the liquid-repellent region 104 remains dry.
  • Many fluidic channels 118 can be formed on a particular substrate 106 to form fluidic network structure designs (siphon networks). For the most efficient fluid removal, the orientation of the liquid-absorptive channels 118 within the fluidic network design should not be completely horizontal when being used.
  • the bottom lowest gravitational region of the channel 118 is called a dripping point 108 .
  • the dripping point 108 is generally where the liquid-absorptive region 102 and adjacent liquid-repellent region 104 meet at the lowest gravitational point of a channel 118 .
  • the fluid flowing down along the length, L, of the channel 118 will accumulate at the dripping point 108 until the fluid forms a droplet 116 that grows big enough to fall away from the material.
  • the width, W, of the channel may vary according a particular application.
  • the structure can be applied to a broad range of moisture management applications. This includes removal of moisture on different surfaces, removal of condensation, spill control, fuel cell electrodes, etc.
  • the moisture can be water, bio-fluid (sweat, urine, blood, etc.), oil, organic solvents and many others.
  • hydrophilic and hydrophobic are general descriptions of a material's affinity for liquid. Use of these terms does not limit the structure to water-related applications.
  • the fluidic channels 118 can be constructed to be curved lines that form an esthetic pattern, such as a heart shape. Alternatively, different lengths of channels 118 can be positioned into a patterned shape, as shown in FIG. 4B .
  • the liquid-absorptive channel pattern can be colored with a different dye on a fabric so that it stands out as a decoration on a garment whether the pattern is wet or dry.
  • the channel 118 should be liquid-absorptive, the thickness of that liquid-absorptive region 102 can be non-uniform throughout the substrate. In other words, part of the liquid-absorptive region 102 can be modified to be less liquid-absorptive or liquid-repellent to further reduce wetness of the fabric and promote fluid management.
  • FIG. 6A shows the inner surface layer of the material that would be in contact with the fluid producing surface, in this example, human skin.
  • FIG. 6B shows a cross-section view of the material and illustrates how the bottom region 602 of the liquid-absorptive region 102 (channel) can be covered by a liquid-repellent layer 604 .
  • FIG. 6C shows the outer surface of the material.
  • the inner surface layer pattern of the material can be as simple as circles or the pattern can be complex.
  • the size of the pattern can be varied.
  • the inner surface layer liquid-absorptive pattern can be larger or smaller than the outer layer pattern size.
  • FIG. 22A and FIG. 22B illustrate an alternative embodiment 2200 where the material comprises liquid-absorptive regions 2202 that are surrounded by less liquid-absorptive regions 2204 to form a liquid-absorptive gradient as opposed to a clear liquid-absorptive liquid-repellant interface.
  • the material comprises liquid-absorptive regions 2202 that are surrounded by less liquid-absorptive regions 2204 to form a liquid-absorptive gradient as opposed to a clear liquid-absorptive liquid-repellant interface.
  • water contacts the material water will move in the direction 2206 from the less liquid-absorptive region to the more liquid-absorptive region due to the wettability gradient as shown is FIG. 22B .
  • This structure does not require liquid-repellent liquid-absorptive contrast but a liquid-absorptive gradient. In other words, the fluid will tend to fill the regions that are more liquid-absorptive.
  • the fluidic channel structure can be created by printing on one side of the material substrate, controlling the penetration thickness to more than half of the material substrate, and then printing again on the other side of the material substrate with more than half penetration.
  • a similar fluidic channel structure can be created but the method requires rotation of the fabric during printing.
  • the two screens need not be aligned during the subsequent printing process. There will always be part of the liquid-repellent pattern that lies on top of the channel pattern.
  • Maintaining good resolution as well as good repellency can be achieved using a repeated printing method. Since the liquid-repellent coating is not strong without heat treatment, a certain amount of ink can be used to print the pattern, followed by a second print once the previous printing has almost dried. If necessary, repeated printing can be used. Since inkjet printing allows control of many parameters, the accuracy of this printing method can be very good.
  • a stitching process may be utilized to form the fluidic network structure on a liquid-repellant material substrate.
  • Liquid-absorptive threads can be stitched or embroidered on a liquid-repellant material substrate to form the fluidic channels.
  • liquid-repellant threads can be tightly stitched on a liquid-absorptive material substrate to define the fluidic channels.
  • the arrangement of the fluidic channels can be designed to specifically remove the sweat generated on different sections of the human body.
  • a garment with a fluidic network structure can remove the moisture from one location utilizing a minimum area of the garment which maintains comfort for the wearer over a long period of time (e.g. during an exercise session or sports match). Since the liquid-repellent regions are completely dry, the permeability of this region remains higher which is beneficial for the evaporative cooling effect on the skin. In addition, the temperature of the liquid-repellent fabric remains higher which is beneficial for reducing the unpleasant chill that can be experienced during and after a workout. According to one test, the temperature of the dry fabric measured 7° C. warmer than a soaked fabric.
  • the front side of the shirt in this embodiment 3600 has three main liquid-absorptive regions.
  • the left and right liquid-absorptive channel chest regions 3606 , 3608 are separated from the main liquid-absorptive channel 3610 by a liquid-repellent region 3620 , 3622 .
  • the main liquid-absorptive channel 3610 runs vertically down the front side of the shirt and carries fluid from the head and neck region 3604 to the two bottom dripping points 3612 , 3614 .
  • the left liquid-absorptive channel chest region 3606 and the right liquid-absorptive channel chest region 3608 carry fluid from the chest to the dripping points 3616 , 3618 on the side of the shirt.
  • the abdomen regions of the front 3620 , 3622 and back 3624 of the shirt remain mostly liquid-repellent since these regions are infrequently in contact with the torso in many postures during sports activities.
  • FIG. 44 is a diagram illustrating another fluidic channel network configuration on a pair of shorts 4400 where fluid-absorptive channels 4402 cover the shorts to transport the sweat to the sides of the shorts and drip it away via the dripping points 4404 , 4406 .
  • the circles 4408 are an example of what the fluidic inlets might look like on the inner layer of the shorts.
  • the fluidic network structure is arranged from the top 4804 of the roof to the bottom 4806 of the tent. For simplicity of illustration, only one section of the fluidic pattern is shown, however, the fluidic network would cover the four sections of the tent.
  • the fluidic network structure can reduce the volume of water that accumulates on the roof, according to the principles previously described.
  • the tent has longer extended half-cylindrical fluid-absorptive channels 4802 and the interior fluidic network arrangement is different.
  • the short “ribs” 4808 of the channels are symmetric around the top of the roof and the long transporting channels 4810 are on the sidewalls 4812 with an angle towards the bottom end of the tent where the moisture can be collected.
  • the force applied is one or more of gravitational force, compression force, capillary force or surface tension force.
