Breathable heat transfer labels
View Patent ↗The present invention relates to a breathable heat transfer label for breathable performance ware. The heat transfer label allows moisture and sweat to pass through and remove moisture from the skin surface to provide comfort to the wearer.
1. A breathable heat transfer label for labeling a fabric, comprising:
a heat transfer adhesive layer having a breathable polymer; and
an indicia layer situated below the heat transfer adhesive layer, the indicia layer comprising a pigment; wherein the indicia layer is between 10 and 50 microns in thickness to provide breathability to the indicia layer;
wherein the heat transfer label has a moisture vapor transmission rate (MVTR) of at least 100 g/m 2 /day when measured in accordance with ASTM E96 Procedure D and at least one layer selected from a group including:
a white layer situated between the indicia layer and the adhesive layer, and
a dye blocking layer situated between the indicia layer and the adhesive layer, or situated between the white layer and the adhesive layer; wherein the label further comprises a non-breathable adhesive, wherein the non-breathable adhesive is pattern printed with spaces between the non-breathable adhesive.
2. The heat transfer label of claim 1 , wherein the breathable polymer is hydrophilic.
3. The heat transfer label of claim 1 , wherein the heat transfer adhesive layer having a breathable polymer at least partially fills the spaces between the non-breathable adhesive.
4. The heat transfer label of claim 1 , wherein the breathable polymer is mixed with a non-breathable polymer.
5. The heat transfer label of claim 2 , wherein the breathable polymer is a water based dispersion or a solvent based dispersion.
6. The heat transfer label of claim 4 , wherein the non-breathable polymer is an acrylic.
7. The heat transfer label of claim 4 , wherein the non-breathable polymer is a rubber emulsion.
8. The heat transfer label of claim 1 , wherein the
non-breathable adhesive further forms a grid structure within the label and a frame around the edge of the label and the heat transfer adhesive layer having a breathable polymer is deposited in spaces in the grid structure.
9. The heat transfer label of claim 1 , wherein the label further comprises a release layer situated below the indicia layer.
10. The heat transfer label of claim 9 , wherein the release layer is a wax having a melting point of 70 to 150° C.
11. The heat transfer label of claim 10 , wherein a release for the release layer is a wax based material or silicone.
12. The heat transfer label of claim 2 , wherein the hydrophilic breathable polymer contains chemical moieties.
13. A performance apparel item, comprising:
a performance apparel item;
a brand identification device comprising;
a heat transfer adhesive layer having a breathable polymer that is a water based dispersion; and
an indicia layer situated below the heat transfer adhesive layer, the indicia layer comprising a pigment; wherein the indicia layer is between 10 and 50 microns in thickness to provide breathability to the indicia layer;
wherein the brand identification device is attached to the performance apparel item and has a moisture vapor transmission rate (MVTR) of at least 100 g/m 2 /day in accordance with ASTM E96 procedure D, wherein the brand identification device further comprising a non-breathable adhesive, wherein the non-breathable adhesive is pattern printed with spaces between the non-breathable adhesive.
