AI Technical Summary

Technical Problem

Existing electrostretching machines suffer from non-uniform material deposition due to constant electric fields causing fiber-particles to accumulate in certain areas, leading to regions of high and low concentration, and repulsive forces between jets resulting in uneven distribution.

Method used

The electrostretching machine employs steering electrodes and variable electric field generation by adjusting the position, shape, and voltage of the injector and collector, along with movable modules and patterned electrodes to control the electric field lines, ensuring uniform fiber-particle deposition across the substrate.

Benefits of technology

Achieves improved material uniformity by canceling out repulsive forces and varying electric field lines, resulting in consistent fiber-particle distribution and reduced defective products.

Abstract

To provide an electrostretching machine with improved material uniformity. [Solution] The present invention relates to an electrostretching machine with improved material uniformity, in which the shape of the electric field generated between the emitter and the collector is changed stably or variably over time, thereby achieving a more uniform deposition of fiber-particles. To do this, the machine comprises a steering electrode (6) positioned at the end of an injector (1), the steering electrode (6) being connected to a power module (5) that applies a potential difference to the steering electrode to exert a repulsive or attractive force on the fiber-particles (4), and a collector (3) comprising conductive material regions (8) positioned on the surface of an insulating material (7) that are electrically insulated from each other, and a voltage which can have a continuous or alternating amplitude and / or phase is applied to the conductive material regions (8).
