摘要： In one embodiment, an electrospinning head has a nozzle unit and a control body. The nozzle unit is arranged opposite to a base material, is applied with a voltage, and thereby is capable of discharging a raw material liquid of fiber. The control body is arranged in the vicinity of the nozzle unit so as to extend to an outside of a spinning space between the base material and the nozzle unit. Further, the control body is applied with a voltage of the same polarity as the voltage to be applied to the nozzle unit, and thereby is capable of making an electric field to be generated at the periphery of the nozzle unit.

摘要： According to one embodiment, an electrospinning head includes a plurality of head units and a coupling structure, and the plurality of head units are coupled to one another through the coupling structure. Each head unit includes a unit main body and a nozzle. Inside the unit main body, a hollow storing a raw material liquid is formed along a longitudinal axis. The nozzle is formed of a conductive material and provided on an outer circumferential surface of the unit main body. The nozzle ejects the raw material liquid supplied through the hollow of the unit main body. The coupling structure connects the plurality of head units in a state where the hollows of the unit main bodies communicate with one another.

摘要： A system and process for making a polymeric fibrous material having increased beta content is provided herein. The system is configured for meltblowing polymer into a fibrous material having high beta crystalline content and has an extruder for melting and moving a polymer to a meltblowing die. The meltblowing die has a longitudinally extending die tip with a plurality of spinnerets substantially equidistantly spaced from each other and a longitudinal fluid material flow through passage disposed along each longitudinal side of the die tip configured to axially attenuate the melted polymer from the die tip in fibrous form. A plurality of liquid spray nozzles are configured and disposed to spray a liquid into the fibrous melted polymer attenuated from the die tip.

摘要： A melt blowing die includes a stack of plates including corresponding melt blowing die tip, die body and air functionalities. One or more rows of polymer filament extrusion orifices extend through in a stack direction across multiple plates of a stack. A gas distribution system within the stack has gas outlets are positioned to provide distributed gas flow to contact and attenuate extruded polymer filaments. One of more polymer distribution channels extend longitudinally through multiple plates in the stack direction to supply polymer to each of the rows of extrusion orifices. A polymer distribution channel is open to receive polymer feed only at a longitudinal end. A melt blowing apparatus has a collection substrate movable in a machine direction that is transverse to a stack direction in a melt blowing die. A method for producing fiber-containing material includes melt blowing using a melt blowing die with a stack of plates.

摘要： Methods are provided for making a porous filter that is useful in polymer melt spinning. The methods include pressing particles, such as a metal powder, to form a filter having a filter body integrally formed with a top cap and a bottom cap. The filter body and caps are formed as a single component or, alternatively, are formed as two or three separate parts that are fitted and pressed together to form a single component having blind inlet and outlet cavities. After pressing, the component is sintered to form the porous filter. The particles are pressed and cohere to form the caps and filter body without the use of a polymeric binder, and the inlet and outlet cavities are formed substantially without machining.

摘要： An extended area filter is provided that is useful in polymer melt spin pack assemblies. The filter is a uniform porous body that is made, for example, of sintered powder metal, and contains multiple opposing spaced apart inlet and outlet cavities. The filter has substantially uniform pore structure and density, and is substantially free from polymer binder decomposition products, allowing for more uniform flow with improved throughput and filtration life.
