Creaking and squeaking sounds

When testing and examining for creaks and squeaks, it is checked if the leather generates creaking noises due to friction. Such noises arise not only in leather but in many other materials, such as rubber, plastics or imitation leather. The main reason these noises develop is when such surfaces constantly rub against each other.

Creaking noise appears, when superimposed layers are alternately adhered to one another within a short time and are then released again. This is dependent on the structure of the surfaces that touch or come in contact. Depending on the number of times contact between these surfaces happen, even surfaces with microscopic unevenness, can stick together under pressure resulting in creasing or squeaking sound, The main influencing factors for this are the pressure at which the surfaces rub against each other, temperature, surface soiling, humidity and material fatigue.

In a vehicle creaking noises can occur everywhere.

 

A common measuring method is the "Slip-Stick-Test": Under standardised contact pressure, a material sample is rubbed against another. Sensors measure the extent of the sticking by means of the delay in the acceleration.


"Antifriction Coatings"

Antifriction coatings are coatings that are designed to reduce or minimise friction on surfaces. The coating eliminate noises by reducing the friction by filling microscopic irregularities of the surfaces, which favour the crease effect. Lubricating lacquers are applied as thin, almost invisible films.

To eliminate squeaks, rattles and other disturbing noise, antifriction coatings are used in the car industry and the furniture industry. But there is also an assortment of products for end users. Disturbing noises don't only occur in cars and in today's widespread functional furniture with many adjustment possibilities, undesirable noise noises occur.


The use of Antifriction Coatings.
