Variety of Technology Needs a Constant Surprise

Conor Peacock (Liverpool, UK)

The variety of technology needs from companies around the world is what makes seeking and securing technology solutions on behalf of those companies so interesting.

On a given day, yet2 personnel may be dealing with a unique engine configuration, illuminated fabrics, or trying to keep two substances from coagulating on contact.

Take this collection of needs, for example. They seek a treatment, a test, a method of manufacturing, and metallurgical and design expertise. You can contact me directly if you have the answer to these needs.

Prevent denim dye transfer:

Leather and vinyl automotive trim covers can be stained by contact with denim. Such seats are coated, but an improved coating (or other method) is needed. The leather industry will not consider solvent-based coatings.

Test method for surface energy of an olefin substrate:

This company must test 100% of the parts in a production line to make sure that a surface treatment has been properly applied prior to using adhesives. Current methods are manual, and very time-consuming. An automated method is needed.

Method to manufacture a toothed ring:

This part is difficult to manufacture because it is thin-walled and flexible. It must also be durable for its application. Several methods have been tried, but have not met the cost/performance targets.

High-speed permanent-magnet rotors:

This may need a metallurgical solution, but design or material solutions may work, too. High-speed rotor suffer fatigue at a slim metal bridge between magnets. The bridge must be thin and strong. It must withstand high centrifugal speeds and not produce parasitical flux between the magnets.

Featured Technology Deal
Nanofiber filtration:

High-efficiency cabin air filters, engine air filters, and oil filters using nanofiber technology.

Created for high-efficiency vehicle cabin filters, engine air filters, and engine oil filters, this new filter medium from DuPont combines a nonwoven scrim bound to a nanofiber web able to filter particles down to 1 micron with minimal cross-filter pressure drops.

Nanofiber nonwovens have been used in filters before, but the DuPont electroblowing process creates a robust nanofiber nonwoven with extraordinary high basis-weight. Basis-weights of 40 gsm have been achieved.

This strong nanoweb, combined with a more conventional scrim, overcomes the problems that others have found in trying to apply nanofiber filtration, and stands up to pleating and similar manufacturing steps, which other nanofiber layers cannot do.

The conventional scrim layer often meltblown or similar nonwoven material intercepts impacting particles and extends the life of the nanofiber layer.

Cabin filters for automotive vehicles, aircraft, construction equipment, engine air filters, and engine oil filters are the expected applications, but the filtration medium can be applied anywhere a strong, highly efficient filtration medium is required.

The high basis-weight nonwoven nanofiber layer is bonded face-to-face with a more conventional nonwoven scrim layer that intercepts incoming particles and extends the life of the nanofiber layer.
