Abstract
Abstract Privacy cubicle curtain cloth suitable for use in hospitals, nursing homes, sanitariums, and the like, capable of providing some measure of privacy between patients in adjacent beds comprising: a warp of saran ribbon or strip materials having a thickness of from about 1- 1/2 mils to about 3 mils and a width of from about 20 mils to about 35 mils; and a frilling of polypropylene spun yarn having a yarn size of from about 8/1 to about 12/1, as calculated on the cotton count system, said privacy cubicle cloth being inherently fire retardant or flame resistant and self-extinguishing, relatively inert chemically in the presence of gases and liquids normally found in hospitals, commercially launderable, and having sufficiently light weight characteristics as to be easily handled and quickly drawn or pulled back in use, while still being opaque or translucent but not transparent to afford some measure of privacy to patients.
