Definitions

  • the present invention relates to a process for forming a fibrous web wherein a polymer stream is spun through a spinning nozzle into an electric field of sufficient strength to impart electrical charge on the polymer and wherein a forwarding gas stream aids in transporting the polymer away from the spinning nozzle.
  • PCT publication no. WO 03/080905A discloses an apparatus and method for producing a nanofiber web.
  • the method comprises feeding a polymeric solution to a spinning nozzle to which a high voltage is applied while compressed gas is used to envelop the polymer solution in a forwarding gas stream as it exits the nozzle, and collecting the resulting nanofiber web on a grounded suction collector.
  • electro-blown spinning refer interchangeably to a process for forming a fibrous web by which a forwarding gas stream is directed generally towards a collection means, into which gas stream a polymer stream is injected from a spinning nozzle, thereby forming a fibrous web which is collected on the collection means, wherein a voltage differential is maintained between the spinning nozzle and the collection means and the voltage differential is of sufficient strength to impart charge on the polymer as it issues from the spinning nozzle.
  • nanofibers refers to fibers having diameters of less than 1,000 nanometers.
  • the local electric field around individual fibers is of sufficient strength that the electrical force becomes the dominant drawing force which ultimately draws the individual fibers to diameters measured in the hundreds of nanometers or less.
  • the geometry of the tip of the spinning nozzle also referred to as the "die tip” creates an intense electric field in the three-dimensional space surrounding the tip which causes charge to be imparted to the web.
  • the die tip may be in the form of a cylindrical capillary or in the form of a linear array of cylindrical capillaries.
  • the forwarding gas stream is issued from gas nozzles 106 on each side of the spinneret 102.
  • the polymer stream fed to the spin pack and discharged through the nozzle in the spinneret is a polymer melt.
  • Any polymer known to be suitable for use in a melt spinning process may be used in the process in the form of a polymer melt.
  • Polymer melts and polymer-solvent combinations suitable for use in the process are disclosed in Z. M. Huang et al., Composites Science and Technology, volume 63 (2003), pages 2226-2230, which is herein incorporated by reference.
  • the moving collection substrate 118 (Fig. 3B) is a nonconductive substrate superposed over a conductive element 120 connected to high voltage, itself superposed on a nonconductive support material 122.
  • the conductive element 120 and/or the nonconductive support material 122 can be stationary.
  • the moving collection substrate 118 is supplied from a supply roll 124 and the combined collected fibrous nanofiber web and collection substrate 118 are sent to a wind-up roll 126.
  • nanofibers and the forwarding gas stream are directed toward the collection substrate 118, where the nanofibers are deposited and collected into a fibrous nanofiber web superposed on the nonconductive collection substrate 118.
  • a nonconductive moving collection substrate 118 according to Fig. 3B can be supplied from a supply roll and fed over the moving conductive belt 110 of Fig. 2. In this manner, a fibrous web containing nanofibers is deposited onto the collection substrate, the combination of nanofiber web and nonconductive moving collection substrate are separated from the moving conductive belt by conventional means and are forwarded to a wind-up roll.
  • the process of the invention avoids the necessity of maintaining the spin pack including the spinneret, as well as all other upstream equipment, at high voltage, as described in the Background of the Invention.
  • the pack, the spinneret and all upstream equipment may be grounded or substantially grounded.
  • substantially grounded is meant that the spinneret may be held at a low voltage level, i.e., between -100 V and +100 V.
  • the polymer discharge pressure is in the range of about 0.01 kg/cm 2 to about 200 kg/cm 2 , more advantageously in the range of about 0.1 kg/cm 2 to about 20 kg/cm 2 , and the polymer solution throughput per hole is in the range of about 0.1 cc/min to about 15 cc/min.

Abstract

La présente invention se rapporte à un procédé d'électrosoufflage amélioré permettant de former une bande fibreuse de nanofibres, selon lequel un flux polymère sort d'une buse à filer dans une filière à l'aide d'un flux de gaz d'envoi, et la bande de nanofibres obtenue est recueillie sur un moyen de collecte. Le procédé selon l'invention consiste à appliquer une tension élevée sur le moyen de collecte, et à mettre la filière à la terre de façon qu'un champ électrique soit généré entre la filière et le moyen de collecte, ledit champ électrique ayant une force suffisante pour appliquer une charge électrique sur le polymère à mesure de sa sortie de la buse à filer.
