Abstract

When ink components are mounted on a moving carrier, transverse movement of the carrier causes sloshing. Bubbles produced by this action can interfere with smooth pumping action and also affect the stream drops leaving the nozzle orifice.

Knitted Fiber Antiink Slosher

When ink components are mounted on a moving carrier, transverse movement of the carrier causes sloshing. Bubbles produced by this action can interfere with smooth pumping action and also affect the stream drops leaving the nozzle orifice.

An inert, low-surface energy fiber (polypropylene) is woven into a knit-like net. The knit structure allows smooth, continuous flow of ink but hinders accelerated flow such as occurs in a sloshing action. The knit structure is characterized by a high-surface area to volume ratio. The high-surface area is responsible for the antisloshing action. The net has negligible weight and displaces less than 5% of the total ink volume of the reservoir. This net can be folded or squeezed to fit into any size or shape of reservoir.

The polypropylene fiber is characterized as a low-surface energy material. The low-surface energy hinders the ink from wetting, and consequently does not retain the ink amongst the fibers when trying to drain the reservoir. This material has exceptional resistance to attack by the ink. Also, the fiber does not alter the chemical nature of the ink. The material will fit any shape or size of reservoir.
