Property Evaluation of Bletilla striataPolyvinyl Alcohol Nano Fibers and Composite Dressings

Abstract EN

This study used nonwoven manufacture and electrospinning to create wound dressings with solid mechanical properties and hemostasis function.

10% Polyvinyl alcohol (PVA) and 5% Bletilla striata (BS) were blended into the PVA/BS solution, which can be made into nanomaterial with high specific surface area by electrospinning.

The PVA/BS solution was electrospun onto the dressing matrix made of polyester (PET) and absorbent cotton (AC), forming the PVA/BS composite dressings.

According to the experiment results, when the volume ratio of PVA to BS was 9 : 1, the resulting dressings had optimal fiber formation, the finest average diameter, and the lowest toxicity.
