Abstract
Fabric materials are disclosed that have been treated with a water resistant and antimicrobial treatment. The water resistant and antimicrobial treatment includes a combination of a durable water resistant composition and an antiviral composition. Protective garments can be made from the fabric that provide protection against airborne pathogens by preventing penetration through the fabric material and by destroying any pathogens that land upon the fabric.
Claims20
A protective garment comprising:
- a fabric material comprising a woven fabric, a knitted fabric, a nonwoven fabric, or combinations thereof, the fabric material having a basis weight from 0.5 osy to 4 osy, the fabric material comprising polyester in an amount greater than 80 wt. %, the fabric material having a yarn density in a warp direction of from 100 yarns per inch to 180 yarns per inch and in a fill direction of from 60 yarns per inch to 120 yarns per inch, the fabric material including a combined water resistant and antimicrobial treatment, the water resistant and antimicrobial treatment containing a combination of a durable water resistant composition and an antiviral composition, the durable water resistant composition comprising a repelling agent and an extender in a weight ratio from 8:1 to 1:3, the antiviral composition including at least one antiviral agent, wherein the antiviral composition comprises a ceramic carrier for the antiviral agent, wherein the antiviral agent comprises one or more ceramic particles, wherein at least a portion of the one or more ceramic particles comprises one or more antiviral metal ions, wherein the weight of the one or more antiviral metal ions of at least one ceramic particle is from 0.1% to 35% based on the total weight of the at least one ceramic particle;
- wherein the protective garment is a medical garment or a lab coat.
A protective garment comprising:
- a fabric material comprising a woven fabric, a knitted fabric, a nonwoven fabric, or combinations thereof, the fabric material having a basis weight from 5 osy to 8.5 osy, the fabric material having a yarn density in a warp direction of 180 yarns per inch or less and in a fill direction 120 yarns per inch or less, the fabric material comprising inherently flame resistant fibers in an amount greater than 70 wt. %, wherein a combined water resistant and antimicrobial treatment is applied to the fabric material, wherein the water resistant and antimicrobial treatment applied to the fabric material comprises a durable water resistant composition, an antiviral composition, and water, the durable water resistant composition comprising a repelling agent and an extender in a weight ratio from 8:1 to 1:3, the antiviral composition including at least one antiviral agent, wherein the antiviral composition comprises a ceramic carrier for the antiviral agent, wherein the antiviral agent comprises one or more ceramic particles, wherein at least a portion of the one or more ceramic particles comprises one or more antiviral metal ions, wherein the weight of the one or more antiviral metal ions of at least one ceramic particle is from 0.1% to 35% based on the total weight of the at least one ceramic particle;
- wherein the protective garment is a fire-safety garment.
