摘要:
The present invention relates to an electrospinning device for manufacturing a nanofiber, and the purpose of the present invention is to provide an electrospinning device for manufacturing a nanofiber, wherein a substrate is transferred while a nanofiber web is stacked and formed on a side surface of the substrate through electrospinning of a polymer spinning solution, and the substrate is rotated during transfer such that the nanofiber web is stacked and formed on the other side surface; accordingly, the nanofiber web can be stacked and formed on both surfaces of the substrate through a single manufacturing process; a drying process is performed simultaneously during rotation of the substrate such that, at the same time the nanofiber web is stacked on both surfaces of the substrate, the substrate is dried through a single manufacturing process, thereby removing any solvent remaining on the nanofiber web; and, as electrospinning devices, electro-blown electrospinning devices and electro-spinning electrospinning devices are installed alternately, such that electro-spinning electrospinning and electro-blown electrospinning can be performed alternately with regard to a transferred substrate.

The present invention provides continuous methods of making ready to use aqueous soy binders comprising extruding in a twin screw extruder wet non-water soluble soy flour in grind phase mixing and, downstream, including further a polycarboxy emulsion copolymer in distributive phase mixing, wherein in the aqueous binders the amount of soy flour solids ranges from 51 to 95 wt.%, based on the total weight of binder solids. The present invention provides continuous and simple methods for providing aqueous binders wherein the soy flour has a sieve particle size ranging from 5 to 44 µm. Making soy flours of such a particle size enables soy flour binder compositions useful as binders for non-wovens, such as mineral fiber or glass mats.
