ABSTRACT:
Disclosed is a nozzle block for electrospinning which is able to simultaneously electrically spin two or more different types of polymer spinning dopes, wherein a single-layer distribution plate for dividing a planar space within the nozzle block into two or more segments is installed within the nozzle block. The apparatus is simple because a single-layer distribution plate is installed instead of a conventional multi layer distribution plate. A hybrid nano fiber laminate can be prepared without any additional laminating procedure because two or more different polymer spinning dopes can be simultaneously electrically spun through different nozzles arranged within the same nozzle block. It is possible to prepare a hybrid nano fiber nonwoven fabric or filaments or the like composed of two or more types of nano fibers different in thermal properties or physical properties because their fiber diameter or polymer type are different from each other.
