Abstract
The present invention relates to an apparatus for the mass production of polymeric nanofibres and their uniform deposition over any substrate. The present invention also provides a method for the manufacture of droplet free polymeric nanofibres by electrospinning process using multi-hole spinnerets. The droplet free polymeric nanofibres of the present invention are preferably of a diameter in the range of 50 nm to 850 nm.
