  • Patent number: 9643033
    Abstract: Nonwoven safety garments include, in some embodiments, features of the stitching which limit the number of particulates emitted from seams between cut edges. Attachments features may be included on the garments to enable secure, external attachment of measuring equipment. Doffing features, such as loops, are provided to help the wearer safely remove the garment, either by helping her pull off part or all of the garment or by starting to separate closure devices, while avoiding contact between the wearer's hands and head, neck or body. In some embodiments, a re-positionable elastic closure on a neck flap covers the neck up to the bottom of a face mask or respirator, and a grasping tab helps the wearer safely open the re-positionable closure and the neck flap without contacting his or her neck or the interior of the garment, thereby avoiding a personal contamination event.
