ABSTRACTMALSHE, PRIYADARSHINI PRAKASH. Enhancing Electrostatic Properties and Hydroentangling Efficiency via Atmospheric Plasma Treatment. (Under the guidance of Professors Marian G. McCord and Mohamed A. Bourham)Keywords:Hydroentangling, atmospheric plasma, nonwoven Hydroentangling is the fastest growing nonwoven bonding technology. Known for the production of most textile-like nonwoven fabric, hydroentangling is a mechanical bonding technique which involves impingement of high velocity water jets onto a nonwoven fiber web. The mechanical action of needle-like water jets entangles fibers and consolidates the web into a fabric. The final properties of a hydroentangled web are reported to depend on the textile material and its intrinsic properties such as strength, modulus, bending rigidity and the fiber surface properties such as friction, fiber shape etc. Hydroentangling efficiency is also shown to depend on fiber to water interaction by way of hydraulic drag force.In previous works by other research groups, water pooling problem has been reported when hydroentangling hydrophobic fibers such as polypropylene. The focus of this work is to eliminate the problem via atmospheric plasma treatment prior to hydroentangling. The purpose of this study is to determine the effects of atmospheric plasma pre-treatment on nonwoven webs due to plasma induced hydrophilicity and other surface modifications such as roughness/smoothness. Different fiber substrates were treated with atmospheric plasma in a continuous run and hydroentangled at different times post-plasma treatment to determine the effect of aging on hydroentangling efficiency.
