Dye-Printing of Polyester Yarns
Project
Using a dye-printing approach, a group of researchers led by B. Fugetsu from Hokkaido University has applied Baytubes® directly to polyester multifilament yarns to form an electrically conductive layer over each filament of the multifilament yarn. The Baytubes® dyestuff was prepared by dispersing Baytubes® agglomerates in water using a blend of zwitterionic and anionic surfactants.
Results
Yarns having electrical resistivity ranging from 103 to 109 ohm/cm were obtained. Yarn with a resistivity of 103 ohm/cm could be used to form flat, soft, and portable electrical heaters by vertically weaving the yarns into fabrics. The 105 ohm/cm yarns could be used for anti-static clothing, and the 109 ohm/cm level yarns for brushes for photocopying machines.
