Abstract
Abstract A composite structure for a protective garment, such as a protective garment for a firefighter, has a moisture absorber, a moisture barrier and an outer shell. The moisture barrier is disposed outwardly in relation to the moisture absorber, while the outer shell is disposed outwardly in relation to the moisture barrier. The moisture absorber has a fibrous matrix incorporating a superabsorbent polymer, as particles or as fibers, and is disposed between an inner cover pervious to moisture and an outer cover. The inner and outer covers may be quilted so as to segregate discrete regions of the fibrous matrix.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
75 words
For a protective garment, a composite structure having a moisture absorber, a moisture barrier disposed outwardly in relation to the moisture absorber, a thermally insulative layer interposed between the moisture absorber and the moisture barrier, and an outer shell disposed outwardly in relation to the moisture barrier, wherein the moisture absorber has a fibrous matrix, which incorporates a superabsorbent polymer and which is disposed between an inner cover pervious to moisture and an outer cover.
Claim 2
Dependent Claim
75 words
For a protective garment, a composite structure having a moisture absorber, a moisture barrier disposed outwardly in relation to the moisture absorber, a thermally insulative layer interposed between the moisture absorber and the moisture barrier, and an outer shell disposed outwardly in relation to the moisture barrier, wherein the moisture absorber has a fibrous matrix, which incorporates a superabsorbent polymer and which is disposed between an inner cover pervious to moisture and an outer cover.
Claim 3
Dependent Claim
16 words
The composite structure of claim 1 wherein the fibrous matrix incorporates particles of the superabsorbent polymer.
Claim 4
Dependent Claim
16 words
The composite structure of claim 1 wherein the fibrous matrix incorporates fibers of the superabsorbent polymer.
Claim 5
Dependent Claim
31 words
The composite structure of claim 1 wherein the inner and outer covers, between which the fibrous matrix is disposed, is quilted so as to segregate discrete regions of the fibrous matrix.
Claim 6
Dependent Claim
31 words
The composite structure of claim 2 wherein the inner and outer covers, between which the fibrous matrix is disposed, is quilted so as to segregate discrete regions of the fibrous matrix.
Claim 7
Dependent Claim
31 words
The composite structure of claim 3 wherein the inner and outer covers, between which the fibrous matrix is disposed, is quilted so as to segregate discrete regions of the fibrous matrix.
Claim 8
Dependent Claim
49 words
The composite structure of claim 1 , 2 , 3 , 4 , 5 , or 6 wherein the moisture barrier is affixed to the outer shell so as to have surface-to-surface adhesion between an outer surface of the moisture barrier and an inner surface of the outer shell.
Claim 9
Dependent Claim
51 words
The composite structure of claim 1 , 2 , 3 , 4 , 5 , or 6 wherein the moisture barrier is affixed to the thermally insulative layer so as to have surface-to-surface adhesion between an outer surface of the thermally insulative layer and an inner surface of the moisture barrier.
Claim 10
Dependent Claim
43 words
The composite structure of claim 1 , 2 , 3 , 4 , 5 , or 6 wherein the thermally insulative layer comprises an inner cover, an outer cover, and a filler between the inner and outer covers of the thermally insulative layer.
Claim 11
Dependent Claim
48 words
The composite layer of claim 9 wherein the moisture barrier is affixed to the outer cover of the thermally insulative layer so as to have surface-to-surface adhesion between an outer surface of the outer cover of the thermally insulative layer and an inner surface of the moisture barrier.
