DEVICE AND METHOD FOR PREPARING CONTINUOUS NANOFIBROUS YARNS AND BUNDLES FROM ELECTROSPUN FIBERS AND FIBRILS

摘要

A device for preparing a continuous nanofibrous yarn comprises an electrospinning chamber, comprising at least one first opening in the upper region of said chamber for receiving gas and a second opening in the bottom region of said chamber for discharging gas and said yarn; means for creating helical movement of gas within said electrospinning chamber; means for introducing a plurality of nanofibres into said electrospinning chamber, wherein said nanofibres are twisted together by said helical movement of gas.
