Home > Swan Carpet > Newproducts carpet is the world's first commercialized carpet using Shell's new PTT(Polytrimethylene Terephthalate) material combined by the innovative technology of Hyosung. Ion free carpet is a revolutionary concept that is environmentally friendly, and has greater stain resistance than nylon carpets. Ion free carpets are also highly resilient and produce low static electricity to provide durability and comfort. Since, there are no chemical bonds between the fiber and stains, all stains can be easily removed with simple water treatment. To protect our customers from germs and microscopic organism, all ion free products are treated with Hass&Rohm, a German company's latest anti-bacterial treatment. Also the low moisture absorbance characteristic of Ion free fiber makes it difficult for germs, microscopic organisms and odor to remain in the carpet. Ion free carpets generate low static electricity by its own characteristics. As a result it is harmless for high tech equipment, and senior citizens that are sensitive to static electricity. All Ion free carpets meet Japan's VOC environmental standards. Ion free is safe and comforting for elders and individuals with allergies, or asthma. negative ions(fuctional group) in staings(nearly all stains contain negative ions) positive ions (fuctional group) in fibers Nylon fibers contain positive ions, while most     stain materials contain negative ions. Nylon's positive ions chemically bond with     negative ions. Due to the chemical bonding, stain remains     within carpet. Different from nylon, Ion free products have no     ions which prevents chemical bonding with     stains Ion free is a revolutionary 21 century material     that has the attribute of both high stain     resistance and durability.
