Thesis Title: Durable Static Control on Fabrics
Thesis Author: Clinton Coletrane
Abstract: Electrostatic charge continues to be a major interest of the textile industry. Electrostatic charge has been harnessed in positive ways such as in electrospinning and flocking. However, its negative effects such as fiber clinging, lapping and electrostatic discharge continue to be problematic for the industry and consumer. As synthetic polymers continue to grow in production and production machinery continue to increase in production speeds, finding a durable antistatic treatment that can prevent the accumulation of charge on a textile surface as well a dissipate charge quickly is becoming increasingly critical. This thesis measured the performance of antistatic treatments on polyester woven fabrics to compare their charge accumulation, dissipation and durability abilities and benchmark their performance with respect to cotton woven fabrics. Two non durable ionic surface treatments as well as two durable hydrophilic surface modifying polymer treatments were applied to spun and filament polyester woven fabrics and then tested for antistatic properties and compared to the control cotton fabrics. The fabrics were charged by means of tribocharging. Charge accumulation and dissipation was measured using newly developed technology at North Carolina State University. Resistivity of the treated fabrics was also measured as a parameter accepted by the 2 industry for a measure of static charge/dissipation, and correlated to the charge accumulation/dissipation measured by tribocharging technique. The results indicate that surface modifying polymer treatments do have an affect, either positive or negative, on the amount of charge accumulated on the surface and its dissipation. The surface modifying polymers also displayed some signs of durability to a single laundering. The anionic treatments were effective on the charge accumulation and dissipation however; durability was questionable. Resistivity was not found to exhibit a strong correlation to charge accumulation or dissipation.
