Abstract
A vapor permeable retroreflective material for use on protective garments. The material may be formed in a non-continuous pattern that provides a high-level of retroreflective brightness, yet also provides adequate permeability to prevent exposure to trapped thermal energy and heated moisture. The non-continuous retroreflective pattern may include retroreflective regions and non-retroreflective regions arranged such that thermal decay through the protective garment is not substantially decreased in the regions corresponding to the retroreflective material. Rather, vapor permeation and thermal decay through the garment may be substantially the same as if the retroreflective material was not present.
Claims20
An article comprising:
- a material;
- and
- retroreflective material formed on at least a portion of the material in a non-continuous pattern to define retroreflective regions and non-retroreflective regions arranged such that the non-retroreflective regions comprise at least 20% of a total surface area of the retroreflective material.
An article comprising:
- a material;
- and
- retroreflective material formed on at least a portion of the material in a non-continuous pattern to define retroreflective regions and non-retroreflective regions arranged such that the non-retroreflective regions comprise at least 25% of a total surface area of the retroreflective material, and wherein the retroreflective material has a reflective brightness of greater than 50 candelas/(lux*meter2).
An article comprising:
- a material;
- and
- retroreflective material formed on at least a portion of the material in a non-continuous pattern to define retroreflective regions and non-retroreflective regions arranged such that the non-retroreflective regions comprise at least 20% of a total surface area of the retroreflective material, wherein each retroreflective region has a surface area of less than four square centimeters, and wherein the retroreflective material has a reflective brightness of greater than 50 candelas/(lux*meter2).
