Electrospun short nylon 6 nanofibers to improve damage resistance of carbon composites 2023-04-12

An Introduction to ElectroSpinning and NanoFibers 2023-04-11

Electrospinning is a process that involves the following: An inherently complex, multi-component material such as the polymer solution A fluidic and electrical equipment often including needles, syringes, and motorized elements for careful control of flow rates and generators providing high voltages The environment external to the process, which may range from air atmosphere to closed chambers operating with controlled gases or in stabilized temperature, vacuum conditions, etc. An automatic syringe pump is used to pump the fluid through a syringe. A voltage is supplied (using several kV potential) to positively charge the syringe needle. As shown in the below images, the resulting electric field causes fibers to be pulled out of the droplet at the end of the syringe tip and onto a grounded metal collector.

Nanofiber filter media for dust collection and fume extraction system 2023-03-17

Blended paper media have been used in industrial dust collection and fume extraction systems for decades. Made up of cellulose (80-85%) and polyester (15-20%) fibers, they collect particles in a variety of dust, fume and/or smoke generating applications, such as metalworking, welding, plasma cutting and laser cutting. With the advancement and availability of nanofiber technology, these filters are now able to collect more – and smaller – particles than ever before, while at the same time lasting longer, using less fan and compressed air energy, and requiring less maintenance than their predecessors
