DESIGNER
PETRA HAIKONEN
Textile designer Petra Haikonen is particularly well-known for her acoustic textiles.
She graduated with a Fashion and Collection Design Master’s Degree from Aalto University in Helsinki.
Petra Haikonen has conducted pioneering research into the relationship between sound and textiles.
In doing so, she has focused on testing, analysing and developing a number of acoustic fabrics.

EN ISO 354
Acoustic absorption is indicated as αw-value which approximately corresponds to the percentage of sound absorbed. For instance, an αw-value of 0,4 translates into 40% absorption of sound. Acoustic absorption of a textile is measured in its flat and draped state.
ABSORPTION
- 0.50/Class D (Absorption flat)
- 0.80/Class B (Absorption folded)
AIRFLOW - 747 PA S/M
EN ISO 9053-1 : Airflow resistance influences the sound absorbing qualities of a textile. Typically, the denser the construction of the textile, the higher the value.

LIGHTFASTNESS 7
ISO 105-B02 : Lightfastness relates to the ability of a textile to retain its colour under light. When testing for lightfastness, samples are exposed to artificial daylight for a specified period. The evaluation scale ranges from 1 (worst) to 8 (best). An increase of one point corresponds to a doubling of the lightfastness, i.e. the same fading takes twice as long.
VISUAL LIGHT TRANSMISSION 21%
Light transmittance indicates the percentage of the visible light penetrating the textile. Densely woven textiles in dark colours usually have a lower light transmittance, whereas loosely woven fabrics in light colours allow more light to pass through.
FIRE TESTS
There are differing requirements concerning the flame-retardancy of textiles dependent on the area of application, country or even region. Our textiles pass the majority of international standards and are also tested for a selection of regional requirements.
