Definitions

  • a method for producing a functional nanofiber layer comprising particles of solid and liquid matter by means of electrospinning of a solution or melt of a polymer, at which the produced nanofibers are laid up between a spinning electrode and a collecting electrode onto a base which is the surface of the collecting electrode or a carrying material.
  • a device for producing a functional nanofiber layer comprising particles of a solid or liquid matter by means of electrospinning of a solution or melt of a polymer between a spinning electrode and a collecting electrode, at which the nanofibers being produced are laid up between the spinning electrode and the collecting electrode onto a base which is the surface of the collecting electrode or a carrying material.
  • nanofibrous layers are usually carried out by means of electrospinning or other well-known methods (usually by means of melt-blowing, drawing or centrifugation). Thereat, small particles are brought into a polymer solution or melt, where they are dispersed. Subsequently, the substance being obtained that way is spun.
  • the second method is based on utilizing the so called coaxial electrospinning. Thereat, a material gets incorporated into the fiber cores, which does not need to be spinnable itself.
  • liquid dispersions of particles of a solid matter or globules of liquid of a suitable size can be used for the purpose.
  • the objective of such solutions is the production of nanofibers obtaining the requested qualities by the incorporation of given particles.
  • the material of the particles can also be removed from the fibers, porous fibers with nano-cavities occurring after the material has been washed out being obtained.
  • CN 101586256 A solves a method for the production of porous electrospun fibers with nano-salt equally dispersed in a polymer solution, a component fiber (polymer + nano salt) being obtained by means of electrospinning. By means of subsequent leaching of the saline solution the salt is separated, openings are created and the final porous fiber is produced.
  • Biologically activated carbon fiber for medical purposes and its production is proposed by CN 101736441 A .
  • Electrospinning and high-temperature sintering is carried out to obtain nanoparticles of calcium phosphate with biological activity in the carbon fibers.
  • the diameter of the carbon fibers varies from 50 to 500 nm; the size of nanometric particles of calcium phosphate varies from 10 to 100 nm; the percentage by weight is between 1 and 10 %.
  • Dispersed nanoparticles of calcium phosphate strengthen the bio-bond between the carbon nanofiber and the bone tissue and usually improve the ability of induced bone development.
  • KR 20090058155 A The objective of KR 20090058155 A is the production of antibacteriological, aseptic and at the same time biologically degradable wrapping paper as a means for filtering air or water.
  • the paper is highly temperature-resistant and mechanically strong. It is made of nanofibers produced by means of electrospinning of a solution having antibacteriological and antiseptic qualities. It contains metallic particles and biodegradable fiber-forming polymer.
  • a part of the WO 2008077372 file deals with the method and device for the production of composite fibrous material.
  • fibers of non-ionic polymer are sulphonated. Sulphonated, and thus anionically behaving fibers mix with a polyamide solution in the next step, to make their behaviour cation-active.
  • the fibers are brought into contact with an anionic dispersion of particles, by means of which the particles get bound to the surface area of the fibers and a fiber-particle composite is produced.
  • CZ 300797 B6 relates to a textile comprising at least one layer of polymeric nanofibers obtained by electrospinning from a polymer solution, the polymeric nanofibers comprising particles of a low-molecular matter.
  • the nanofibers of the low-molecular matter are products of a chemical reaction of the low-molecular matter antecedent dissolved in a polymeric solution and a chemical agent applied onto the nanofibers after their spinning.
  • the polymer solution for spinning contains a low-molecular matter antecedent.
  • the low-molecular matter antecedent together with the polymer are pulled into the nanofibers being produced.
  • a suitable chemical agent is used to act on the antecedent contained in the nanofibers, by means of which the low-molecular matter antecedent transforms into a low-molecular matter.
  • CZ 297774 B6 solves the method of the production of photocatalytically active TiO 2 .
  • the production starts from a very cheap raw material - alkaline titanate, which is the by-product of the production of titanium white.
  • the titanate is acted upon by glycol while being heated up and the mixture is then processed by sulphuric acid.
  • the product is photocatalitically active TiO 2 of nanofibrous morphology.
  • a bio-material based on nanofibrous layers consists of at least two nanofibrous layers, covered by living cells growing on their both sides interconnecting those layers.
  • the nanofibrous layers are unwoven and are composed of synthetic polymers or copolymers of monomers selected from a group comprising methacrylic acid esters, methacrylic acid amides, urethanes, vinyl alcohol and monomers derived from lactic acid and its derivatives, and the method of its preparation.
  • the cells are sown on an unwoven layer of nanofibers.
  • CZ 2008-241 A3 makes a wrapping agent public, which is namely a wrapping agent comprising woven or unwoven textile comprising nanofibers and evaporative corrosion inhibitors.
  • CZ20096-148 makes an electrospinning device public, containing two serial separated spinning apparatuses. The first of them generates a supporting layer of nanofibers, microfibers and/or liquid nanoparticles containing polyisobutylene on the carrying material. The second spinning device lays the actual functional layer of nanofibers onto the base. The double device is expensive, actually solving only the perfection of the bond of certain functional nanofiber layers to the carrying material and having only an indirect influence on the qualities of the functional nanofiber layer.
  • the methods and devices according to the prior art are particularly complicated, not dealing with continuous manufacturing of the final composite product, which in the case is a system of nanofibers with particle material invested. Moreover, the quality of the products depends on the required synchronization of the individual steps of its production.
  • the objective of the invention is to relieve the shortages of the prior art or to reduce them to a significant extent and to propose a reasonably priced method of production of a nanofibrous layer allowing to influence its functional qualities by means of adding powdery particle material.
  • the objective of the invention is achieved by means of a method for producing a functional nanofibrous layer comprising particles of either a solid or a liquid matter, the goal of which is that particles are brought into the nanofibrous layer by joint action of gravitational forces, when the particles are guided along an inclined skid plate ended with a sharp edge, and the action of high voltage between a base and the particles which by contacting the charged edge of the skid plate acquire an electric charge consistent with the charged edge, whereby at the same time, ionization of the gaseous environment occurs and electric wind is formed, leading away from the sharp edge of the skid plate, which helps with the transport of the particles being incorporated to the surface area of the collecting electrode.
  • the movement of the particles on the inclined skid plate is facilitated by vibrations of the skid plate.
  • the objective of the invention is also achieved by means of a device for the production of a functional nanofibrous layer comprising solid or liquid matter particles, in which at least one tank with an outlet opening for batching the solid or liquid matter particles is arranged behind the place and/or in the place of deposition of the nanofibers towards the base, the principle of which is that the outlet opening of the tank is coupled with a skid plate equipped with a sharp edge at its end facing the base, the skid plate is connected to a high voltage power supply. That allows to produce a narrow current of electric wind directed away from the sharp edge, which facilitates the transport of suitably sized particles into the wind current and further to the desired place.
  • the skid plate is connected to an outlet member of a vibrator, whose vibrations facilitate the transport of the solid particles.

  • a device according to the invention is represented, intended for a continuous production of a nanofibrous layer with incorporated particles.
  • a part of the collecting electrode 2 is belted with a band of carrying material 8, led by a pair 81 of intake rollers before the collecting electrode 2 and by a pair 82 of off-take rollers after the collecting electrode 2 .
  • another spinning electrode 12 is placed in the vicinity of the part of the collecting electrode 2 circuit opposite to the spinning electrode 1
  • FIG. 6 another embodiment of the device according to the background art is represented, intended for a continuous production of a nanofibrous layer with incorporated particles.

  • the current of electric wind in the S3 direction away from the edge 61 is very narrow (forming a so called stream); that is why quick flux occurs in the vicinity of it, helping transport suitably sized particles into the current and further to a required place, i.e. to the surface area of the collecting electrode 2 virtually simultaneously with the stream of nanofibers leaving the outlet nozzle 11 of the spinning electrode 1.
  • the like electric charge obtained by the particles contacting the charged edge 61 is utilized.
  • the like charged particles then repel each other and obstruct the bunching of minute particles.

  • the electrospraying system according to Fig. 4 uses a strong electric field to transport the particles. By means of it, the surface level of the spraying liquid transported through the outlet tube 72 from the reservoir 71 for the spraying liquid gets unbalanced, whereupon small droplets occur through so called electrospraying.

  • the collecting electrode 2 of the device according to Fig. 5 is partly banded with a carrying material 8 band. Its continuous motion in the S4 direction is derived from the rotation of the collecting electrode 2 in the S2 direction or the interaction of the pair 81 of the input rollers and the pair 82 of the off-take rollers, which are linked to non-represented driving means.
  • a layer of nanofibers produced by the spinning electrode 1 is primarily produced, followed by the particles from tanks 4, 3 being gradually incorporated into that layer and overlayed by a layer of nanofibers produced by the spinning electrode 12 afterwards.
  • the band of carrying material 8 covered in a multicomponent nanofibrous layer is taken off by means of a pair 82 of off-take rollers for storing purposes or further processing.
