Carpet is a key decorative element and provides the foundation of decorating through the use of color and texture. Recently the carpet industry has lost market share in commercial settings due to perceived relationships between carpeted areas and an increase in illness, asthma and allergies. The use of soft floor coverings in schools, hospitals and other health care facilities has long been controversial as carpet is thought to contribute to the presence of microorganisms in the indoor environment. Indoor air is a complex mixture of bioaerosols and non-biological particles. Among the most important of these are human and animal occupants that shed skin scales and other fragments, mold spores, viruses, and bacteria.
It has advantages for general places like mosques, and also for children rooms.
This product is an antibacterial carpet contining silver nano particles.
In nano-dimension, antibacterial effect of silver increases significantly, so that they are able to destroy over 650 bacterial species. It is reported that these nanoparticles have significant antifungal activities against some ringworms. Ag nanoparticles interact with sulfur and phosphorus compounds of membrane proteins affecting cell morphology and structure, causing its death. With decreasing particle size, the release of silver ions increases, leading to increasing their antibacterial activities.
The final product was washed 10 times by relying on the INSO 7664. This product shows high antibacterial activity according to INSO 11070 (Textiles- Determination of antibacterial activity of textile products). The following table clarifies how high its activity against E.Coli and S.aureus bacteria is.
|Antibacterial Activity after washing||Antibacterial Activity before washing|
|2||2||Acceptable standard level|
|2.16||2.03||Nano Sample (klebsiella pneumoniae)|
|2.53||2.06||Nano Sample (S.aureus)|
Antibacterial activity is an indicator of the product ability to eliminate bacteria. It is obtained by comparison of bacteria number present on control and nanometric samples after 24 hours’ exposure. According to standard, When the antibacterial activity of the product is between 2 and 3, the effectiveness is good. If antibacterial activity is greater than 3, the effectiveness is intense and strong.
