  • Evaporative cooling is a natural phenomenon relying on evaporation to provide cooling.
  • the use of evaporative cooling is cost effective as less energy and resources - if any - are required than in refrigeration systems.
  • a liquid such as water wets a surface, and evaporates as it absorbs heat from the surface or its environment.

  • causing the evaporation of at least some of the moisture includes preventing the moisture-retaining layer from reaching a humidity saturation level.
  • generating heat by exposure of a heat-generating layer to near infrared or to infrared radiation includes generating heat by exposure to sunlight.
  • Fig. 1 is a schematic sectional view of an evaporative cooling textile in accordance with the present disclosure.
  • an evaporative cooling textile in accordance with the present disclosure is generally shown at 10.
  • the evaporative cooling textile 10 has a flexible (i.e. , non-rigid) panel body.
  • a panel body may be regarded as having substantial length and width relative to a thickness.
  • the evaporation cooling textile 10 is shown as being constituted of three different layers, though the textile 10 may have more than the three different layers described herein.
  • the textile 10 has at least:
  • a heat-generating layer 40 for retaining ambient heat and/or absorbing ambient heat and/or generating heat.
  • the interface layer 20 may be against the moisture-retaining layer 30.
  • the moisture-retaining layer 30 may be against the heat-generating layer 40.
  • the expression “be against” may indicate that main surfaces of the layers 20 and 30, and of the layers 30 and 40 are coplanar. While the evaporative cooling textile 10 may not be flat, especially when worn or used, the expression coplanar may be used to indicate that non-flat planes of the surfaces of the layers 20 and 30, and 30 and 40, are in contact regardless of how the evaporative cooling textile 10 is shaped.
  • the interface layer 20 is selected so as be in contact with a user’s skin A, hair and/or other external soft tissue.
  • the interface layer 20 is made of a material that is hydrophobic, allowing moisture to pass through it, yet without absorbing the moisture.
  • the material repels moisture.
  • the interface layer 20 is a woven fabric, with yarns having such moisture repellent properties.
  • the weaving is well suited to define moisture passages (i.e., pores).
  • the moisture passages may be for instance in the interstices between the yarns and/or threads constituting the interface layer 20. Moisture diffusion may occur through the fibers and the interstices between the mass of fibers constituting the yarns.
  • An exemplary material for the yarn of the interface layer 20 is polypropylene.
  • the hydrophobic properties of the yarn of the interface layer 20 may also be achieved through the use of hydrophobic coatings. It could be spun yarn, filament, a combination of both woven or knitted in the fabric form.
  • the linear density of the yarn or filament used for this interface layer 20 may be between 70 deniers up to 700 deniers.
  • the interface layer 20 may be a knitted fabric, for example. The interface layer 20 therefore assists in reducing the amount of moisture on the skin, by allowing moisture to evacuate.
  • the interface layer 20 plays the role of a relatively dry top sheet, a.k.a., a dry feel layer, that remains relatively dry through its moisture repellent properties, combined to the absorbing properties of the moisture-retaining layer 30.
  • the interface layer 20 may also be qualified as being a non-wetting layer.
  • a moisture-retaining layer 30 is laid onto the interface layer 20 by any appropriate arrangement, such as stitching, laminating, bonding, etc, with combinations, thereof.
  • the interconnection between the interface layer 20 and the moisture-retaining layer 30 must not or does not hamper the flow of moisture from the skin A to the moisture- retaining layer 30, via the passages in the interface layer 20.
  • the moisture-retaining layer 30 is made of a material that is for example hydrophilic that absorbs the moisture.
  • the moisture-retaining layer 30 is a wetting layer, in that liquid present has a tendency to remain in contact with the yarns/threads of the moisture-retaining layer 30.
  • the interface moisture-retaining layer 30 is a woven fabric.
  • the moisture-retaining layer 30 therefore acts as a reservoir for the moisture generated by or circulating on the skin A.
  • the moisture-retaining layer 30 may also assist in wicking or pumping the moisture away from the skin A, through the passages of the interface layer 20.
  • the combination of the interface layer 20 and the moisture-retaining layer 30 performs some wicking action, with the moisture-retaining layer 30 drawing humidity, for instance by capillary action, with the interface layer 20 serving as a moisture conveyor isolating the skin from the wetted moisture-retaining layer 30.
  • a heat-generating layer 40 forms the outer exposed surface of the textile 10. Accordingly, the heat-generating layer 40 may be exposed to the elements, including sunlight, if the textile 10 is part of a garment that is worn outside, without being covered by a protective shell.
  • the heat-generating layer 40 is laid onto the moisture-retaining layer 30 by any appropriate arrangement, such as stitching, laminating, bonding, etc, and any combination thereof provided the interconnection between the moisture-retaining layer 30 and the heat-generating layer 40 does not substantially affect heat exchange between the moisture-retaining layer 30 and the heat-generating layer 40.
  • the heat-generating layer 40 is made of a material that has the capacity of generating heat from infrared or near infrared exposure. In an embodiment, the heat-generating layer 40 is a woven fabric.
  • One type of yarn and/or filament that may be used for its heat generating capacity is a ceramic-doped yarn.

  • evaporative cooling textile 10 It is possible to add other functionalities to the evaporative cooling textile 10. For instance, it is contemplated to used stretch yarns (like corespun spandex) or cut-resistant yarn (like glass core or metallic core) in the woven or knitted fabric that compose the layers 30 and/or 40. Other layers beyond the three different layers 20, 30 and 40 described above include fabric construction that would create during weaving or knitting two or even 3 more layers in one single manufacturing operation. Modern knitting machines for example may allow the production of two faces material. It is possible to design a single fabric that may incorporate layer 20 and layer 30 or layer 30 and 40 in the same knitted fabric. The same can be achieve with a weaving machine. A linear density of the yarns or filaments of the layers 30 and 40 may be between 70 deniers and 700 deniers.

Abstract

L'invention concerne un textile qui comprend une couche d'interface conçue pour s'appliquer contre une surface humide, la couche d'interface étant constituée d'un matériau hydrophobe dont les pores laissent passer l'humidité à travers la couche d'interface. Une couche de rétention d'humidité peut être disposée contre la couche d'interface, la couche de rétention d'humidité étant constituée d'un matériau hydrophile conçu pour retenir l'humidité. Une couche de génération de chaleur peut être disposée contre la couche de rétention d'humidité, la couche de génération de chaleur étant constituée d'un matériau pouvant générer de la chaleur lorsqu'il est exposé à un rayonnement infrarouge proche ou à un rayonnement infrarouge. La couche de génération de chaleur est en relation d'échange thermique avec la couche de rétention d'humidité de sorte que la chaleur générée par la couche de génération de chaleur évapore l'humidité retenue par la couche de rétention d'humidité à travers la couche de génération de chaleur.
