Abstract
The present invention is generally directed to a method of treating a folded garment to achieve good alcohol repellency on the innermost layers of the folded garment.
Claims15
A method for treating a folded garment comprising:
- providing a garment in a folded configuration, the garment made of a fabric layer having opposite exposed faces, at least a portion of the fabric layer having an alcohol repellency rating of 6 or less, the garment being folded along at least a first fold line, a second fold line and a third fold line, the second and third fold lines intersecting the first fold line, wherein the fabric layer is folded multiple times upon itself when the garment is in the folded configuration;
- and
- subjecting the folded garment to a plasma treatment that penetrates the garment in its folded configuration such that the three innermost fabric layers of the folded garment have an alcohol repellency rating of at least 7.
A method for treating a folded garment comprising:
- providing a garment in a folded configuration, the garment made of a fabric layer having opposite exposed faces, the garment being folded along at least a first fold line, a second fold line and a third fold line, the second and third fold lines intersecting the first fold line, wherein the fabric layer is folded multiple times upon itself when the garment is in the folded configuration so as to define at least 15 fabric layers within at least one cross-section of the folded garment, wherein each of the at least 15 fabric layers in the at least one cross-section remains unattached to and separable from the exposed faces of the adjacent fabric layers in the cross-section;
- and
- subjecting the folded garment to a plasma treatment that penetrates the garment in its folded configuration such that a fluoro-chemical monomer is graft polymerized onto at least a portion of each of the fabric layers, the alcohol repellency rating of the innermost fabric layers of the folded garment being increased by at least 2.
