  • This structure shown in Figure 2C represents the final fabrication in which the presence of release material layer 31 protects and covers pressure sensitive adhesive material 32.
  • This resulting structure may be stored until needed for application to a user's skin.
  • Figure 2D sets forth the present invention structure prepared for use in which release material layer 31 has been removed exposing pressure sensitive adhesive material 32 for adherence to skin surface 34 of a user's body.
  • the present invention apparatus is then positioned as desired with respect to skin surface 34 and thereafter pressed against skin surface 34 to secure the inventive apparatus to the user's skin.
  • pressure sensitive adhesive 32 is selected to be a removable adhesive allowing the entire apparatus to be removed from the user's skin.
  • material or fabric layer 33 is preferably formed of a suitable material such as fabric, woven or non-woven, foam, paper or plastic material.

  • Release material layers 31 and 32 may be fabricated of a suitable paper or plastic material which is coated with a release agent thus providing the releasable characteristics from a sticky adhesive material or mastic.
  • the pressure sensitive adhesive utilized for adhesive material layer 32 is preferably formed utilizing a silicone liquid or silicone gel which is water repellent or water resistant.
  • the pressure sensitive adhesive material should have an adhesion to the surface of the base material or fabric which is substantially greater than its adhesion to human skin.

Other commercially available materials may be selected without departing from the spirit and scope of the present invention.
  • Pressure sensitive adhesive materials are further suitable for use in inventive method and fabrication due to their capability to sustain either two way or four way fabric stretching and their ability to provide a strong attachment while nonetheless being capable of easy release from the skin surface when removal is desired. This is particularly important when the present invention apparatus is utilized in a body support application as set forth below.
  • the pressure sensitive adhesive is partially cured after application to the base material or fabric such that a thin adhesive layer may be formed without the need for a thermoplastic film or barrier. Both the base material or fabric layer and the pressure sensitive adhesive are selected to provide sufficient stretch and flexibility to mold to the user's body and accommodate user movement and stretching.
  • the heat curing operation of the present invention method and fabrication is selected in accordance with the characteristics of the pressure sensitive adhesive and base or fabric materials being utilized. Thus, for certain fabrics temperature ranges of forty degrees to one hundred forty degrees may be utilized while heavier fabrics may utilize temperatures ranging from one hundred degrees to two hundred degrees centigrade.
  • adhesive layer 32 is formed of an unsaturated water soluble silicone gel or liquid or an unsaturated silicone containing a tackifier.
  • the resulting sandwich is then rolled through an oven at an elevated temperature such as sixty degrees centigrade to two hundred degrees centigrade preferably utilizing eighty degrees centigrade to one hundred eighty degrees centigrade to partially cure the pressure sensitive adhesive silicone gel. Because this process removes a portion of the liquid within the adhesive, the application thereof to the base material or fabric layer prevents the adhesive material from bleeding through the fabric material layer.
  • an adhesive layer is formed utilizing an unsaturated pure silicone gel or liquid containing a thermally activated catalyst such as platinum.
  • a thermally activated catalyst such as platinum.
  • curing temperature is between sixty and two hundred degrees centigrade with a preference of eighty to one hundred eighty degrees centigrade to partially cure the silicone gel.

  • Figures 3A through 3D set forth sequential partial section views of an alternate embodiment of the present invention adhesively attachable material apparatus which differs from the embodiment shown in Figure 2 in that the base or fabric material layer provides a water proof characteristic.
  • base material layer 33 may utilize a fabric having an outer surface which is water proof while simultaneously having an inner surface which is absorbent in characteristic.
  • the embodiment set forth therein provides a base or fabric material layer which exhibits a waterproof outer surface characteristic and absorbent inner surface characteristic by using a pair of material layers secured by conventional attachment such as sewing or adhesive.

  • the material includes at least one thermoplastic elastomer which has the advantage of reversible crosslinking.
  • Covalently crosslinked polymers such as a thermoplastic, cannot be recycled because they don't melt. They don't melt because the covalent crosslinks tie all the polymer chains together, making it impossible for the material to flow.
  • Reversibly crosslinked polymers according to preferred embodiments of the invention use noncovalent, or secondary interactions between the polymer chains to bind them together. These interactions include hydrogen bonding and ionic bonding.
  • crosslinks By using noncovalent interactions to form crosslinks, when the material is heated, the crosslinks are broken. This allows the material to be processed, and most importantly, recycled. When it cools again, the crosslinks reform. Glass temperature is the temperature above which a polymer becomes soft and pliable, and below which it becomes hard and glassy. If an amorphous polymer has a glass temperature below room temperature, that polymer will be an elastomer, because it is soft and rubbery at room temperature. If an amorphous polymer has a glass temperature, above room temperature, it will be a
  • thermoplastic because it is hard and glassy at room temperature. So a general rule of thumb is that for amorphous polymers, elastomers have low glass temperatures and thermoplastics have high glass temperatures.
  • High-elastic TPU hot melt double sided adhesive film or thermoplastic elastomer is preferred in the embodiment shown in Figure 8 because it comes with numerous microstructure nano-scale gas molecules and the composite material is breathable however, there are no water molecules in the TPU hot melt adhesive film making it water resistant and or waterproof.

  • the pressure-sensitive adhesives of the present invention are especially useful for multiple uses, meaning more then one time and not necessarily consecutive days and can be washed and reused.
  • the pressure sensitive adhesive is soft, breathable, highly elastic and soft to the skin making it painless to remove.
  • Another aspect of this invention relates to medical devices, including compression devices and wound dressings, which incorporate such poly [urethane-(meth)acrylate] pressure-sensitive adhesives therein.
  • the fabric combined with the adhesive can enhance blood flow and oxygenation, accelerate the healing process and prevent germ entry. It is also a benefit that the silicone adhesive can reduce unwanted scars resulting from injury, surgery, burns, including severe forms that are hypertrophic or keloid. It also may be used on stretch marks after pregnancy.
  • these can be used as therapeutic bandages, wraps, heat and ice packs, pads and eye pads. These items may also be used for animal care such as EyeOn.

  • the entire sandwich construct is then rolled through an oven system at an elevated temperature such as 60-200°C, preferably 80-180°C or UV system to partially cure the layer of adhesive. This process removes a portion of the moisture contained in the adhesive so that when applied to fabric or other material the adhesive does not bleed through the fabric to the other side.

Abstract

La présente invention concerne un procédé de fixation d'un adhésif, par exemple de la silicone autocollante sur un matériau, dans le cadre duquel l'adhésif est directement appliqué sur un matériau en utilisant ou pas une couche de support. Ce procédé est adapté aux pansements médicaux et aux produits de soin des plaies possédant une première face imperméable à l'eau et une seconde face comportant un adhésif permettant son maintien en place sur la peau. Ledit pansement protège à la fois de l'humidité et de l'infection et sert de support. Une adaptation de l'invention concerne un système de support corporel visant à supporter des tissus affaissés ou lésés. Ledit matériau peut correspondre à un tissu utilisé pour les vêtements.
