The present invention involves a cleaning sleeve for cleaning the oral cavity, suitable to be applied over a finger or a tool to clean the inside of the oral cavity. The cleaning sleeve has a flat-layered structure comprising a sleeve portion formed by laminated sheet-like fabrics and a grip portion formed by a single-layer sheet-like fabric, wherein the sleeve portion comprises a working layer and a sleeve layer; the working layer and the sleeve layer form a head at the top, of the cleaning sleeve; and the grip portion is integrally extended from the Working layer. The cleaning sleeve is formed by ultrasonically bonding the two sides of a piece of folded degradable nonwoven fabric.

MULTI-DIE MELT BLOWING SYSTEM FOR FORMING CO-MINGLED STRUCTURES AND METHOD THEREOF
20200216979 · 2020-07-09 ·

A melt blowing system for the manufacturing of pleatable/moldable nonwoven fabrics includes a collector positioned to receive a plurality of fibers, a first die in fluid communication with a first liquid polymer supply having a melt flow index of about 500 or lower, and a second die in fluid communication with a second liquid polymer supply having a melt flow index of about 500 or higher. The first die has a concentric air design, includes a plurality of spinneret nozzles facing the collector surface, and is configured to draw a first plurality of fibers. The second die includes a plurality of spinneret nozzles having smaller capillary diameter than those of the first die and is positioned to draw a second plurality of fibers such that the first and second pluralities of fibers form a co-mingled nonwoven web with varying fiber diameters on the collector surface.

Microfluidic control surfaces using ordered nanotube fabrics

A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.
