Abstract

Fabric sound is comprised as
fabric handle property such as fabric softness, stiffness and drape. As the
previous studies were reviewed, it could be seen that, in general different
sound generation systems were used in which the fabric was pulled in a constant
velocity. In these measurement systems, a fabric sample was rubbed against the
face of another fabric sample and the friction occurred face to face. However,
in some actions, friction is not always face to face. There are several
different movements (such as jogging) and friction types in which the physical
properties such as friction, roughness, shear, and bending stiffness act
important role on fabric sound. In order to imitate all these situations,
“waving movement sound” was designed. In addition to this, “frictional movement
sound” was also defined and used to compare waving movement sound with the
common (caused by face to face friction) frictional sound.

 

The aim of this study is to
investigate the sound generation properties of the fabrics under the influence
of different frictions and movements. For this purpose, three different
commonly used woven fabrics and three military windcheater fabrics were used
and “Level Pressure of Total Sound (LPT)” values of these were measured during
“frictional movement” and “waving movement”. According to the results, since
frictional movement created higher friction force, LPT values of the frictional
movement was found higher than the LPT values of waving movement. Higher
bending rigidity and higher kinetic friction coefficient (µ) values increase
frictional sound. In conclusion, smoother, thinner and softer surfaces supply
lower LPT values in both “frictional movement” and “waving movement” sounds.
