Medical protective clothing materials

Protective clothing materials and related methods and garments are provided. In some embodiments, a protective clothing material may comprise a fibrous layer that serves as a barrier to certain fluids (e.g., bodily fluids, water) and microbes. The impermeability of the fibrous layer may be due, at least in part, to the structural uniformity and/or relatively small pore size of the fibrous layer. In some embodiments, the fibrous layer may have a relatively high air permeability that imparts beneficial properties (e.g., relatively high air flow, breathability) to the protective clothing material without adversely affecting its protection rating. In certain embodiments, the protective clothing material may also comprise one or more coarse nonwoven webs that impart beneficial properties (e.g., splash resistance) to the protective clothing material. The protective clothing materials, described herein, may be particularly useful for a wide variety of applications, including the formation of AAMI level 4 protective garments.

20240227362 · 2024-07-11 ·

A glass facer for a constructions board includes a first non-woven layer of coarse fibers and a second non-woven layer of coarse fibers and microfibers. The glass facer also includes a binder that simultaneously binds or adheres the coarse fibers of the first non-woven layer together, the coarse fibers and the microfibers of the second non-woven layer together, and the first non-woven layer to the second non-woven layer. The first non-woven layer has a porosity and air permeability that enables the first non-woven layer to absorb a material of the construction board when the glass facer is positioned atop the construction board during manufacture of the construction board. The second non-woven layer is configured to block the material of the construction board from passing through the glass facer to an exterior surface of the second non-woven layer so that the material is not externally visible.
