Abstract
The SBR film including a carbon black(Ketjen black, Denka black or Vulcan XC-72) was hot press laminated onto several fabrics. The carbon black incorporated SBR rubber(CB-SBR) film laminated fabrics were investigated in terms of resultant morphology, antistatic properties. The antistatic effect was observed from the loading level 2.5~5.0 wt% by lowering the specific resistivity below 10 $\Omega$.cm and loading the carbon black more than 10 wt% gave rise to conductivity by lowering the specific resistivity below 10 $\Omega$.cm. Above the relative humidity 50% the frictional electrostatic voltage generated by rubbing the CB-SBR laminated fabrics with cotton fabric remained nearly independent of the loading level of carbon black, whereas the frictional electrostatic voltage was notably diminished with increasing the loading level if the relative humidity is lower than 40%. Among the carbon blacks Ketjen black gave the highest antistatic efficiency, followed by Denka black and Vulcan SC-72. The increasing order of the frictional electrostatic voltage of the CB-SBR laminated fabrics with the same carbon black content was cotton, PET/cotton blend, wool, PET/wool blend, nylon, and PET. The critical content of carbon black in the CB-SBR laminated fabries producing a stable antistatic property(lower than 1kV) was dependent on the nature of the fabric 5~10 wt% for PET and nylon, 2.5~10 wt% for PET/wool blend, 2.5~5 wt% for wool, 1~5 wt% for PET/cotton blend, and 0.5~1 wt% for cotton.
