Parasitic acari barrier
A parasitic Acari barrier fabric that impedes parasitic Acari movement, traps parasitic Acari, and/or exterminates parasitic Acari thereon or therein. The barrier fabric includes an outer face formed from open mesh construction having evenly spaced openings formed thereon that are adapted for passing parasitic Acari from outside the fabric to inside the fabric, an inner face that is breathable and configured for moisture vapor transmission from a wearer's skin therethrough but is impenetrable to parasitic Acari passed to the inside of the fabric, and an intermediate spacer that extends between and interconnects the inner face to the outer face to form the parasitic Acari barrier fabric.
1. A parasitic Acari barrier fabric adapted to impede parasitic Acari movement, trap parasitic Acari, and/or exterminate parasitic Acari thereon or therein, the fabric comprising:
(a) an outer face formed from open mesh construction having evenly spaced openings formed thereon that are adapted for passing parasitic Acari from outside the fabric to inside the fabric, each opening having a diameter ranging from 3 to 5 mm;
(b) an inner face spaced apart from the outer face, the inner face is breathable and configured for moisture vapor transmission from a wearer's skin therethrough but is impenetrable to parasitic Acari passed to the inside of the fabric; and
(c) an intermediate spacer that extends between and interconnects the inner face to the outer face to form the parasitic Acari barrier fabric, wherein:
each opening of the outer face, the inner face, and intermediate spacer forms individual compartments inside the fabric configured to impede parasitic Acari movement, trap and/or exterminate parasitic Acari therein;
the evenly spaced openings of the outer face have a density ranging from 1 to 9 openings/cm 2 ;
the intermediate spacer has a length ranging from 0.5 mm to 3.0 mm in a direction extending from the inner face to the outer face; and
the intermediate spacer is formed of V needle stitch construction.
2. The parasitic Acari barrier fabric of claim 1 , wherein each yarn in the intermediate spacer has an angle of intercept ranging from 45° to 85°.
3. The parasitic Acari barrier fabric of claim 1 , wherein the inner face is formed of pillar inlay stitch construction.
4. The parasitic Acari barrier fabric of claim 2 , wherein the inner face has a moisture vapor transmission rate ranging from 0.020 to 2.0 kPa s/m under ambient conditions.
5. The parasitic Acari barrier fabric of claim 4 , wherein the fabric has an overall thickness ranging from about 0.5 to 10 mm in a relaxed state.
6. The parasitic Acari barrier fabric of claim 5 , wherein at least one of the outer face, inner face, and intermediate spacer are treated with an acaricide.
7. The parasitic Acari barrier of claim 6 , wherein the acaricide is microencapsulated.
8. The parasitic Acari barrier fabric of claim 5 , wherein at least any two of the outer face, inner face, and intermediate spacer are treated with an acaricide.
9. The parasitic Acari barrier of claim 8 , wherein the acaricide is microencapsulated.
10. The parasitic Acari barrier fabric of claim 5 , wherein each of the outer face, inner face, and intermediate spacer are treated with an acaricide.
11. The parasitic Acari barrier of claim 10 , wherein the acaricide is microencapsulated.
12. The parasitic Acari barrier fabric of claim 1 , wherein the fabric further comprises a tubular body configured for donning on a wearer's limb.
13. The parasitic Acari barrier fabric of claim 1 , wherein the tubular body is a gaiter.
14. The parasitic Acari barrier fabric of claim 1 , wherein the fabric comprises a puttee configured for wrapping around a wearer's limb or appendage.
