Abstract: A knitted fabric, including: a front face and a rear face, wherein the front face includes a first plurality of fibres of at least one of a first colour, a first colour combination, a first material and a first material combination, and the rear face includes a second plurality of fibres of at least one of a second colour, a second colour combination, a second material and a second material combination, the fabric having a knit pattern wherein the first plurality of fibres are at least partially separated from the second plurality of fibres, such that the front face is visually different when compared to the rear face.

Abstract: A knitted fabric (10) including a plurality of parallel chains of knitted loops (12), with each chain of knitted loops (12) formed from a respective yarn, and with the parallel chains of knitted loops (12) extending in the warp or vertical direction. The fabric (10) also includes a plurality of weft yarns (14), with each weft yarn (14) connected to and extending across at least two adjacent chains of knitted loops (12). Each chain of knitted loops (12) is also associated with at least one respective yarn 16, (18) that is connected to, and intertwines along the chain of knitted loops (12).

Abstract: An apparatus including a lens, a gasket to receive the lens and a frame removably coupled to a respirator helmet is defined. The gasket forms a seal with a respirator helmet. The frame secures the lens within the gasket and defines a release mechanism to enable a quick release of the frame from the respirator helmet.
