Title:
METHOD AND APPARATUS FOR PRODUCING MATS OF MICROFIBRES AND/OR NANOFIBRES FROM POLYMERS, USES THEREOF AND LINING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/144980
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and method for producing nanofibre nonwovens from polymers. The method for producing micro-fibre and/or nanofibre nonwovens from polymers comprises the use of high-speed electrospinning and jet-spinning elements. The disclosed apparatus for the production of microfibre and/or nanofibre nonwovens from polymers comprises a compressed gas source, a pressure regulator, a hypodermic syringe with a pump for controlling the injection rate of the polymer solutions, a spraying apparatus and a collector with a preferably controlled speed of rotation. The disclosed microfibre and/or nanofibre nonwoven production technology can produce microfibres and nanofibres with diameters similar to those obtained by electrospinning, including on an industrial scale. The invention further comprises the use of nanofibre nonwovens for spraying living tissues and for lining materials.
