Title:
FILTER MEDIUM HAVING NANOFIBERS ON BOTH SIDES OF BASE AND HAVING IMPROVED HEAT RESISTANCE, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/137095
Kind Code:
A1
Abstract:
The present invention relates to a filter medium having nanofibers on both sides of a base and a manufacturing method therefor for overcoming the low thermal stability of conventional nanofiber filters, the filter medium having improved heat resistance by stacking the polymeric nanofibers on both sides of the base using electrospinning. The present invention is characterized by producing polymeric nanofibers on both sides of a base by successive electrospinning and thereby manufacturing a functional filter medium having process efficiency and price competitiveness and ensuring high efficiency and heat resistance.
