Latest Patents
One of his latest patents is titled "Methods of saturating nonwoven fabrics with liquid and the making of electret thereof." This patent describes a method of preparing an electret by saturating a nonwoven fabric with a liquid, such as water, and subsequently removing the liquid via suction. This process generates charges through friction between the fabric fibers and the liquid. The saturating can be performed by impinging the bottom side of the fabric with jets of water while the fabric is being pulled under a solid roller. Additionally, excess water can be applied during a water quenching step of a meltblowing or spunbonding process. An apparatus for preparing an electret according to these methods is also detailed in the patent.
Another significant invention by Tsai is "Meltblown composites and uses thereof." This invention focuses on a porous composite that features an inlet face and an exit face. It comprises intermingled meltblown fibers and staple fibers, which create a density gradient from coarse pores at the inlet face to fine pores at the exit face. This innovation has potential applications in filtration and other areas requiring specific porosity characteristics.
