Particulate blocking undergarment

Abstract

A particulate blocking undergarment for workers operating in hazardous environments. The undergarment adds particulate blocking technology to an undergarment (men's and women's brief, bra) that provides a protective barrier to significantly reduce the risk of exposure to carcinogens and infiltration around protective over garments. The protective barrier includes a plurality of layers including an inner flame retardant layer and an outer particulate blocking layer. The inner layer may include a Polartech® Power Stretch FR® material—and/or other material per NFPA 1975. The outer layer may include a Stedfast, Stedair® Prevent material—and/or other materials per NPFA 1971.

What is claimed is: 
     
         1 . A particulate blocking undergarment, comprising:
 a brief structure having a waistband, and a pair of leg openings;   a front pouch dimensioned to cover a groin area and a front panel extend from the front pouch along a medial aspect of each leg of the brief structure;   a leg panel extends from a lateral aspect of the front panel and wraps around a lateral aspect each of the pair of leg openings to join with a back panel dimensioned to cover a medial portion of a wearer's buttocks;   a saddle interconnects each of the front pouch, the front panel, the leg panel, and the back panel; and   a pouch overlay, a front panel overlay, a back panel overlay, and a saddle overlay, formed of a particulate blocking material is attached to the respective pouch, front panel, back panel, and saddle, each formed of a flame retardant material.   
     
     
         2 . The particulate blocking undergarment of  claim 1 , wherein:
 the particulate blocking material having a particulate blocking efficiency of at least 90%.   
     
     
         3 . The particulate blocking undergarment of  claim 1 , wherein each of the front pouch, the front panel, the back panel, and the saddle are a cotton-poly-spandex material. 
     
     
         4 . The particulate blocking undergarment of  claim 1 , wherein each of the pouch overlay, the front panel overlay, the back panel overlay, and the saddle overlay have a particulate blocking efficiency of at least 99%. 
     
     
         5 . A particulate blocking undergarment, comprising;
 an inner layer formed of a flame-retardant material formed as an undergarment; and   an outer layer formed of a particulate blocking material, the outer layer affixed to a portion of the inner layer and dimensioned to overly a sensitive skin area of a user.   
     
     
         6 . The particulate blocking undergarment of  claim 5 , wherein:
 the particulate blocking material has a particulate blocking efficiency of at least 90%.   
     
     
         7 . A particulate blocking undergarment, comprising:
 a sports bra structure formed of a stretch cotton-poly-spandex material; and   a frontal protective panel formed of a particulate blocking fabric overlying the sports bra structure, the frontal protective panel dimensioned to cover at least a breast area of a wearer.   
     
     
         8 . The particulate blocking undergarment of  claim 7 , wherein the particulate blocking fabric has a particulate blocking efficiency of at least 90%. 
     
     
         9 . The particulate blocking undergarment of  claim 7 , wherein the particulate blocking fabric has a particulate blocking efficiency of at least 99%. 
     
     
         10 . The particulate blocking undergarment of  claim 7 , wherein the particulate blocking fabric covers a portion of a back panel of the sports bra structure.
