Abstract
The invention relates to a hydrophilic cotton lap constituted 100% of cotton fibers.

The external layers and enclosing the central layer are webs. The lap of the invention is used in the form of packaged or formatted units of hydrophilic cotton.
Claims25
A hydrophilic cotton lap composed 100% of cotton fibers, the lap comprising:
- three cohesive cotton layers, said layers being a first external cotton layer forming a plane, a second external cotton layer forming a plane, and a central cotton layer positioned between said first external cotton layer and said second cotton layer,
- wherein said first external cotton layer and said second external cotton layer are carded webs, and said central cotton layer comprises stratified cotton fibers oriented in a substantially oblique manner between said planes formed by said first external cotton layer and said second external cotton layer.
A hydrophilic cotton product in formatted units composed substantially of cotton fibers, the product comprising:
- three cohesive cotton layers, said layers being a first cotton layer forming a plane, a second cotton layer forming a plane, and a central cotton layer positioned between said first cotton layer and said second cotton layer;
- and
- at least one external layer, said at least one external layer being disposed about said first cotton layer, wherein said at least one external layer is formed in part by cellulose fibers, and
- wherein said first cotton layer and said second cotton layer are each a carded web, and said central cotton layer comprises stratified cotton fibers oriented in a substantially oblique manner between said planes formed by said first cotton layer and said second cotton layer.
A hydrophilic cotton product in formatted units composed substantially of cotton fibers, the product comprising:
- three cohesive cotton layers, said layers being a first cotton layer forming a plane, a second cotton layer forming a plane, and a central cotton layer positioned between said first cotton layer and said second cotton layer;
- and
- at least two external layers wherein a first external layer is disposed about said first cotton layer and a second external layer is disposed about the second cotton layer, and wherein each of said at least two external layers are formed in part by cellulose fibers, and
- wherein said first cotton layer and said second cotton layer are each a carded web, and wherein said central cotton layer comprises stratified cotton fibers oriented in a substantially oblique manner between said planes formed by said first cotton layer and said second cotton layer.
