Description

technical field [0001] The invention relates to a fiber mat preparation device, in particular to a needleless batch fiber mat preparation device. Background technique [0002] The mass production of electrospinning has become a research hotspot among scholars. The spinneret of the traditional electrospinning device uses needles, and its output is generally 0.1-1.0g / h, and the needles are easily blocked during the electrospinning process. If a multi-needle array is used for batch electrospinning, the "edge effect" phenomenon will occur because the electric fields between the needles interfere with each other, so the expected spinning efficiency cannot be achieved. [0003] Many scholars have conducted research on needle-free batch electrospinning technology, such as Chinese patent CN102191573A. Compared with the needle-type electrospinning technology, these technical solutions better solve the problems such as the easy clogging of the spinneret and the "edge effect" of the ...
