Design and Evaluation of Spinneret Module with Line-Type and Multi-Holes of Electro-Spun

Abstract:

For the wide application in the field of filtration and bio-medicine, the purpose of this study is to design a spinneret module of electro-spun which can produce composite nonwoven with sub-micrometer fiber continually. Applying the principle of melt-blown, a spinneret module with line-type and multi-holes which was assembled with small beads and filtering net, was designed. In order to construct a continual electro-spun production line, a traversal device was designed to control the traverse-motion of spinneret module for the even lapping and a stainless plate was adopted as collecting plate. In condition of 41KV working voltage, 0.3573 mL/min throughput and 42cm CSD (Capillary-Screen-Distance), a continual PEO nonwoven can be produced with average fiber diameter of 576nm and of CV% 13.4%. To a sampling area of 10cm×10cm and basis weight of 7.257 g/m2 electro-spun nonwoven, the CV% of gray level of its image is 2% and its filtration efficiency is up to 91.2% with pressure drop 13.8mm-H20 by TSI 8130 (32LPM, 5% NaCl).
