Abstract

An article of apparel includes a fabric portion having an inside and an outside defined by the article of apparel. A ceramic print is provided on the inside of the fabric portion. The ceramic print includes at least five percent of a ceramic by weight and covers at least ten percent of the inside of the fabric portion. A method of manufacturing the article of apparel includes first printing an ink comprising at least five percent of a ceramic by weight onto a first side of a fabric portion in order to provide a fabric with a ceramic print that covers at least ten percent of the inside of the fabric portion. The method further includes incorporating the fabric with the ceramic print into a garment with the first side of the fabric portion exposed on an inside of the garment.

First claim

What is claimed is:

1. An article of apparel comprising:
fabric incorporated into the article of apparel, the fabric including:
an inner, user-facing surface having a surface area, and
an outer surface; and

a discontinuous ceramic layer applied to the inner fabric surface, the discontinuous ceramic layer defining printed portions and non-printed portions, the printed portions covering the inner fabric surface and the non-printed portions exposing the inner fabric surface, wherein the ceramic comprises molten silica, and the printed portions of the discontinuous ceramic layer covers from 20% to 80% of the surface area of the fabric inner surface,
wherein each printed portion of the discontinuous ceramic layer comprises at least two percent ceramic by weight.

2. The article of apparel of claim 1 , wherein each printed portion of the discontinuous ceramic layer comprises between five percent and fifteen percent of the ceramic by weight.

3. The article of apparel of claim 2 , wherein each printed portion of the discontinuous ceramic layer comprises about ten percent of the ceramic by weight.

4. The article of apparel of claim 1 , wherein each printed portion of the discontinuous ceramic layer comprises a binder and at least two percent of a ceramic powder by weight.

5. The article of apparel of claim 1 , wherein:
the printed portions define a plurality of linear members; and
the non-printed portions define a plurality of channels, each channel being positioned between adjacent linear members.

6. The article of apparel of claim 1 , wherein the article of apparel including the discontinuous ceramic layer exhibits improved heat retention compared to an article of apparel lacking the discontinuous ceramic layer.

7. The article of apparel of claim 1 , wherein the printed portions of the discontinuous ceramic layer comprise a plurality of linear members oriented in spaced relation, each linear member absorbing and retaining heat.

8. The article of apparel of claim 7 , wherein each printed portion of the discontinuous ceramic layer comprises a binder.

9. The article of apparel of claim 8 , wherein the binder is polyurethane.

10. The article of apparel of claim 1 , wherein the printed portions of the discontinuous ceramic layer define areas of improved heat retention, the areas of improved heat retention being oriented in spaced relation from each other along the inner fabric surface.

11. The article of apparel of claim 1 , wherein the printed portions are applied directly to the fabric inner surface.

12. The article of apparel of claim 1 , wherein the printed portions include the ceramic and a binder effective to adhere to the fabric.

13. The article of apparel claim 1 , wherein the printed portions contact the inner fabric surface.

14. The article of apparel of claim 1 , wherein each printed portion of the discontinuous ceramic layer comprises at least five percent ceramic by weight.

15. The article of apparel of claim 1 , wherein the discontinuous ceramic layer is positioned to contact a wearer of the apparel.

16. The article of apparel of claim 1 , wherein the discontinuous ceramic layer is positioned on inside of the article of apparel such that the discontinuous ceramic layer contacts a wearer of the apparel.
