Abstract

Abstract A prefolded and sewn diaper and fabric therefor comprising at least two plies of material characterized by providing increased fabric density and a less open construction than conventional gauze diaper material for increased wear resistance in a first one of the plies and providing less fabric density and a more open construction than conventional gauze diaper material for increased moisture-holding characteristics in a second one of the plies. The diaper and fabric therefor preferably includes two spaced-apart warpwise extending strips in the first ply of material which have a greater fabric density and a less open construction for increased wear resistance than the remaining portion of the first ply and are so located as to form the outside folded edges of the prefolded and sewn diaper for combating wear therealong.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 241 words
A woven prefolded and sewn diaper having a multilayer center panel and side panels on each side thereof and being formed from an unfolded diaper blank comprising two plies of material superimposed on each other and extending throughout the length and width of said diaper blank and having opposed selvage edges joining said plies together and opposed cut edges, said unfolded diaper blank being characterized by providing increased fabric density and a less open construction than conventional gauze diaper material in a first one of said plies for increased wear resistance and providing less fabric density and a more open construction than conventional gauze diaper material in the second of said plies for increased moisture-holding characteristics while retaining a combined fabric density, weight, warp end count and filling pick count for both said plies within the ranges of conventional gauze diapers, said first ply of material having a warp end count throughout greater than a conventional range of 37-39 for providing the aforesaid characteristics, said second ply of material having a warp end count throughout less than a conventional range of 37-39 for providing the aforesaid characteristics, and said diaper blank being folded in such a manner so that said first ply of material forms the entire outside surface of said prefolded and sewn diaper for combating wear therealong and said second ply of material forms inside layers of said prefolded and sewn diaper for providing greater moisture-holding characteristics internally thereof.
Claim 2
Dependent Claim 241 words
A woven prefolded and sewn diaper having a multilayer center panel and side panels on each side thereof and being formed from an unfolded diaper blank comprising two plies of material superimposed on each other and extending throughout the length and width of said diaper blank and having opposed selvage edges joining said plies together and opposed cut edges, said unfolded diaper blank being characterized by providing increased fabric density and a less open construction than conventional gauze diaper material in a first one of said plies for increased wear resistance and providing less fabric density and a more open construction than conventional gauze diaper material in the second of said plies for increased moisture-holding characteristics while retaining a combined fabric density, weight, warp end count and filling pick count for both said plies within the ranges of conventional gauze diapers, said first ply of material having a warp end count throughout greater than a conventional range of 37-39 for providing the aforesaid characteristics, said second ply of material having a warp end count throughout less than a conventional range of 37-39 for providing the aforesaid characteristics, and said diaper blank being folded in such a manner so that said first ply of material forms the entire outside surface of said prefolded and sewn diaper for combating wear therealong and said second ply of material forms inside layers of said prefolded and sewn diaper for providing greater moisture-holding characteristics internally thereof.
Claim 3
Dependent Claim 45 words
A woven prefolded and sewn diaper, as set forth in claim 1, in which said first ply of material has a warp end count within a range of 40-64 and said second ply of material has a warp end count within a range of 16-36.
Claim 4
Dependent Claim 69 words
A woven prefolded and sewn diaper, as set forth in claim 1, in which said first ply of material includes two spaced-apart warpwise extending strips therein having a greater fabric density and a less open construction for increased wear resistance than the remaining portion of said first ply, said strips being so located as to form ouTside folded edges of said prefolded and sewn diaper for combating wear therealong.
Claim 5
Dependent Claim 61 words
A woven prefolded and sewn diaper, as set forth in claim 3, in which said first ply of material has a warp end count within a range of 40-64, said second ply of material has a warp end count within a range of 16-36, and said strips in said first ply have a warp end count within a range of 66-90.
