Latest Patents

Hershelman holds a patent for a "Method for producing filter material formed of melt-blown non-woven mat." This patent describes a process where a fiber-forming thermoplastic polymer resin is extruded in molten form through a series of nozzles into a stream of hot gas. This process attenuates the molten resin into fibers that are collected on a receiver, forming a non-woven mat. The method includes the use of at least two spaced rows of nozzles to produce distinct fiber streams, which are then collected to create layered mat portions. Additionally, different materials can be injected between these fiber streams, resulting in a collected structure that sandwiches the different material between the non-woven mat portions.
