Abstract
A biodegradable monolayer medical material, comprising at least 15 percent cellulose fibers by dry weight, with a remainder comprising at least 60 percent by dry weight of natural fibers, the monolayer medical material providing a barrier to liquids and/or microorganisms meeting at least level 1 performance based on a standard defined by AAMI PB70, and at least a portion of the monolayer medical material comprises a softening process pattern configured to soften the monolayer medical barrier material.
Claims35
A biodegradable monolayer medical material, comprising at least 15 percent cellulose fibers by dry weight, with a remainder consisting of at least 60 percent by dry weight of natural fibers,
- the monolayer medical material providing a barrier to liquids and/or microorganisms meeting at least level 1 performance based on a standard defined by AAMI PB70 (2008 version),
- wherein at least a portion of the monolayer medical material comprises a softening process pattern configured to soften the monolayer medical barrier material.
A method for manufacturing a biodegradable monolayer medical material, comprising:
- preparing a furnish comprising at least 15 percent cellulose fibers by dry weight, with a remainder consisting of at least 60 percent by dry weight of natural fibers;
- forming a sheet from the furnish in a wet-laid process;
- drying the sheet;
- and
- forming a pattern on and/or within the sheet via a softening process configured to result in a softening of the sheet and a barrier performance of the sheet to at least level 1 based on a standard defined by AAMI PB70 (2008 version).
