Self-deodorizing polyoxometalate-modified fabrics or cellulosic fibers that can be used to remove gaseous contaminants from the air.
- Able to remove contaminants from both the gas and liquid phases.
- Removes contaminant within milliseconds of contact and for extended periods of time.
- Enhances water resistance, surface area, dyeability, and light and color fastness properties of fabric.
Cigarette smoke, exhaust gases, nicotine, and rotten food-these are some of the deleterious toxic gases that contaminate the air we breathe. Certain Japanese textiles are able to remove gaseous contaminants by incorporating deodorizing components in the fabric. However, these fabrics also require higher reaction temperatures and pressures to promote catalytic activity. This requires the addition of other compounds to the fabric to activate the deodorizing properties which is not very practical or economical.
This invention incorporates a catalytically active compound, polyoxometalate, into textiles and fabrics, which increases the ability of the fabric to remove toxic, offensive, and odorous compounds from both the gas and liquid phase. These self-deodorizing fabrics can be used in clothing, furniture, curtains, carpets, or paper to remove or degrade the toxic compounds within milliseconds of contact and can be used both at home and the workplace. Furthermore, polyoxometalate modified fabrics and cellulosic fibers have the advantage of enhanced water resistance and dyeability properties.
