Since many studies have suggested that allergic diseases have increased in frequency, the supplier of specialty chemicals Devan Chemicals NV, Ronse/Belgium, has launched a technology to make textiles free from allergens shed by cats and dogs. Purissimo is a probiotic-based solution and therefore completely natural. Test results show a significant reduction of 92.8 % on the amount of cat hair allergen Fel d 1 found in treated samples.
Inactive probiotic bacteria are encapsulated into microcapsules. These microcapsules are then integrated into textiles. When the fabric is exposed to friction, the microcapsules break open and release the spores. The spores absorb humidity, are then transformed into probiotic bacteria and start to consume the organic matter which contains the various allergens that cause allergic reactions and asthma.
Since pet allergens are also found in homes where there are no pets (because of dispersion by adherence to textile surfaces such as clothing and shoes), Devan’s solution could be used to treat household textiles such as carpets, curtains, upholstery fabrics, etc., resulting in a clean, fresh and allergen-free environment. It is also suitable for use in public spaces like schools, hospitals, libraries, etc., where the technology could be used to prevent the dispersion of pet allergens and ‘second-hand’ exposure.
