Abstract
A method for producing a woven personal respirator mask includes providing a plurality of warp ends into an electronic woven label loom, programming the loom to weave the warp ends into a sheet having a repeating mask pattern in the weave direction, the mask pattern comprising an edge border having a tight weave and defining therein a filter section, the filter section having a tubular weave to define an outer layer and an inner layer, at least one of the outer layer and an inner layers comprising a filter weave, and at least one intermediate interlock fastening at least a point of the outer layer to an opposing point on the inner layer, and cutting the sheet to separate the repeating mask pattern into individual mask parts with a hot-wire slitter.
Claims20
A method for producing a woven personal respirator mask, which comprises:
- providing a plurality of warp ends into a weaving loom;
- programming the loom to weave the warp ends into a sheet having a repeating mask pattern in a weft direction, the mask pattern comprising:
- an upper edge;
- a lower edge;
- a left lateral side having a tight weave;
- a right lateral side having the tight weave;
- an upper side having the tight weave;
- a lower side having the tight weave;
- a left woven tube extending parallel to the warp ends from the upper edge to the lower edge, having a tubular weave, and comprising:
- an upper end at the upper edge between the left lateral side and a left end of the upper side;
- and
- a lower end at the lower edge between the left lateral side and a left end of the lower side;
- a right woven tube extending parallel to the warp ends from the upper edge to the lower edge, having a tubular weave, and comprising:
- an upper end at the upper edge between the right lateral side and a right end of the upper side;
- and
- a lower end at the lower edge between the right lateral side and a right end of the lower side;
- a filter section having a tubular weave to define an outer layer and an inner layer and defined by an upper edge of the lower side, a lower edge of the upper side, a right edge of the left woven tube, and a left edge of the right woven tube, at least one of the outer layer and an inner layers comprising a filter weave;
- and
- at least one intermediate interlock fastening at least a point of the outer layer to an opposing point on the inner layer;
- cutting the sheet to separate the repeating mask pattern into individual mask parts;
- and
- securing an elastic ear cord through each of left and right woven tubes to create a pair of ear-securing loops for each mask part and form a woven personal respirator mask.
