Abstract
Abstract A process for specially treating the surfaces of absorbent fibrous surgical products such as towels, surgical drapes and the like. After the subject treatment, the products formed can be folded, stacked and packaged without appreciable fiber entanglement developing between contiguous surfaces of the products. Importantly, the products can be subjected to sterilizing radiation while folded in their package, and may thereafter be readily unfolded without sticking or blocking as might otherwise result from the exposure to sterilizing radiation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
A surgical product of the type which is folded to be packaged and subsequently radiation sterilized, comprising a moisture absorbent web of fibrous sheet material having a binder present on said surface in a first given pattern so that fibers of said material are exposed at given areas adjacent said first given pattern, and a release agent applied to said surface in a second lattice-like given pattern which overlies a portion of said binder and a portion of said fibers exposed at said given areas.
Claim 2
Dependent Claim
85 words
A surgical product of the type which is folded to be packaged and subsequently radiation sterilized, comprising a moisture absorbent web of fibrous sheet material having a binder present on said surface in a first given pattern so that fibers of said material are exposed at given areas adjacent said first given pattern, and a release agent applied to said surface in a second lattice-like given pattern which overlies a portion of said binder and a portion of said fibers exposed at said given areas.
Claim 3
Dependent Claim
11 words
The product of claim 1, wherein said release agent comprises silicone.
Claim 4
Dependent Claim
90 words
A packaged sterile surgical product comprising a moisture absorbent folded web of fibrous sheet material having a binder present on contiguous folded surfaces of said material in a first given pattern so that fibers of said material are exposed at given areas adjacent said first given pattern, and a release agent applied to said surfaces in a second lattice-like pattern which overlies a portion of said binder and a portion of each of said fibers exposed at said given areas, said packaged product being sterilized by exposure thereof to radiation.
Claim 5
Dependent Claim
90 words
A packaged sterile surgical product comprising a moisture absorbent folded web of fibrous sheet material having a binder present on contiguous folded surfaces of said material in a first given pattern so that fibers of said material are exposed at given areas adjacent said first given pattern, and a release agent applied to said surfaces in a second lattice-like pattern which overlies a portion of said binder and a portion of each of said fibers exposed at said given areas, said packaged product being sterilized by exposure thereof to radiation.
Claim 6
Dependent Claim
12 words
The packaged product of claim 3, wherein said release agent comprises silicone.
Claim 7
Dependent Claim
30 words
The packaged product of claim 4, wherein said second given pattern of release agent overlies from about 15 to about 18 percent of the first given pattern of said binder.
