2.8.2.1 Research projects and products<br />
Textile with sonic properties is also object of research in the framework of the Swedish programme<br />
IT+Textiles of the Interactive Institute. The project ‘Mute’ is based on the idea of sound-absorbent<br />
textile surfaces in public, office, school or daycare settings. In this case the textile changes its spatial<br />
form as a response to certain conditions. In order produce a textile that has different acoustic<br />
properties depending on its state, changes in its surface are necessary. For this purpose a model of<br />
textile blocks sliding in and out between in each other was created. It uses tiny pneumatic cylinders<br />
and a compressor. Thus, the fabric changes its acoustic properties by stretching, as with stretching<br />
the fabric its ability to dampen the sound is reduced. So far, this project is mainly conceptual, but it will<br />
progress [8].<br />

A further examples of the use of ceramics in textiles is Masonic N from Kanebo, which is a Nylon<br />
filament with ceramic microparticles incorporated.<br />
Auxetic materials<br />
By definition, an auxetic (or negative Poisson’s ratio) material expands in all directions when pulled in<br />
only one, giving therefore a deformation kinematics opposite to that of ‘conventional’ materials.<br />
They are developed for sutures, although they are demanding strength and expansion.<br />
Commercialised products are far away.<br />
They are also used for arterial prostheses (where any extensive blood pressure results in a firming of<br />
the arterial wall) and artery dilators (where tension can be applied to expand auxetic sheats laterally)<br />
W.L.Gore has commercialised a PTFE (GoreTex PTFE) that is used in arterial sheats.<br />
The German curtain and decorative textile manufacturer ADO International marketed a fabric that can<br />
split up harmful substances, like nicotine or formaldehyde, into their harmless elements carbon dioxide<br />
and water vapour. The so-called ActiBreeze textile is based on a photocatalytic reaction. When light<br />
