The experiment findings showed that Sonovia’s ultrasound technology raised the fabrics’ water resistance to level 100, the maximum possible level, for each fabric sample studied.
Sonovia, an Israeli cloth product maker, reported on Monday that a new experiment revealed that their proprietary ultrasound technology was capable of bringing fabrics to the maximum degree of water resistance according to international standards.
Sonovia achieved this degree of water resistance with “significantly lower concentration level of active ingredients that currently used water-resistance methods,” and without the use of harmful chemical contaminants such as PFOS and PFOA.
The experiments were carried out at the Qima International Laboratory in compliance with the International Standard for the Testing of Water Immunity – AATCC-22, as well as the standards and specifications of Sonovia’s commercial partner, and the results showed that each fabric sample tested had a level 100 water resistance, the highest possible level.
The technology also needs to be tested in an external lab and is scheduled to complete this process of product development by the end of this month.
The global demand for chemical compounds that impart global waterproof properties is expected to be worth about $800 million per year.
Today, the chemical compounds used for imparting waterproof properties that exhibit the highest efficiency for water resistance as well as the highest resistance to household washes are dependent on the chemical compounds PFOA (Perfluorooctanoic acid) and PFOS (Perfluorooctanoic sulfonic acid) (perfluorooctane sulphonate).
Both of these compounds are currently being rigorously investigated by various regulatory authorities around the world due to suspicions that they are carcinogenic, cause DNA mutations, affect fertility, and act as long-lasting toxins in nature and the human body.
According to Sonovia, businesses in this industry expect that the usage of these materials would be limited or prohibited in the coming years, necessitating the development of alternatives to impart water-resistant qualities to fabrics without the use of these materials thus preserving comparable efficiency.
