Abstract
Abstract A fabric which is coated on at least its upper exposed surface with a heat-reflective and heat-retentive metallic coating containing from about 85% to about 99% copper. The copper is coated with a non-metallic material such as a silicate or silicon oxide. The fabric of the invention is particularly useful in covers for ironing boards, pressing machines and the like, but is useful in any application which calls for a heat-reflective, heat-retentive, flexible, porous metallized fabric.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
87 words
An ironing board cover, comprising: (a) a porous fabric having an upper, exposed surface, (b) the fibers of said fabric on said surface and for at least a region below and bounded by said surface being coated by a composition pressure-printed thereon, said composition comprising a metallic component, said coating being porous and permitting said surface to substantially retain its fabric texture, flexibility and porosity while being heat reflective, and wherein such region is heat retentive, (c) said metallic component having at least 85 weight percent copper.
Claim 2
Dependent Claim
87 words
An ironing board cover, comprising: (a) a porous fabric having an upper, exposed surface, (b) the fibers of said fabric on said surface and for at least a region below and bounded by said surface being coated by a composition pressure-printed thereon, said composition comprising a metallic component, said coating being porous and permitting said surface to substantially retain its fabric texture, flexibility and porosity while being heat reflective, and wherein such region is heat retentive, (c) said metallic component having at least 85 weight percent copper.
