Definitions

  • the present invention relates to a process for trapping liquids, coloring or not, with or without pigment, in a nonwoven fabric and to the implementation of said process.
  • This masking is carried out for example using a cover which globally protects the entire vehicle.
  • covers may include panels making it possible to release surface elements (door, wing, front cover, etc.) to be repainted, according to French patent No. PV. 46.310 of the applicant corresponding to DE-B 1 646 100.
  • a flexible paper cover is applied to the edges of the cut panel and to the sheet metal, and precisely delimits the surface to be treated. Since the cover is stuck on the entire perimeter of the surface, there can be no paint leakage towards the remaining surface of the bodywork.
  • the cover and the protective clothing receive stains and fine particles of paint. These dry out and may flake off.
  • very fine scales of paint are drawn into the projection and sprayed with the paint on the bodywork.
  • the scales produce a grainy effect which should be avoided.
  • the protective material used effectively protects against direct splashes, it does not retain the paint which, once dry, can come off.
  • the present invention aims to provide a solution to these drawbacks.
  • the invention relates to a process for trapping liquids, coloring or not, with or without pigment, in a textile made of fibers, nonwoven, and the implementations of said process and it is characterized in that said textile is metallized under vacuum by spraying metal particles onto at least one face of the textile and over a portion of its thickness so that the surface fibers, or in the immediate vicinity of the surface, are coated with metal while remaining independent of each other.
  • the subject of the invention is also a use of a textile consisting of fibers, nonwoven and metallized only over part of its thickness with metal particles sprayed on at least one face, the surface fibers or in the immediate vicinity of the surface. being coated with metal while remaining independent of each other, as protective masking for carrying out painting work on bodies or bodywork parts.
  • FIG. 1 represents the implementation of the trapping method according to the invention
  • FIG. 2 represents a first variant implementation of the trapping method according to the invention
  • FIG. 3 represents a second variant of implementation of the trapping method according to the invention.
  • FIG. 4 represents a detailed view of the trapping of liquid according to the method of the invention.
  • FIG. 5 represents a variant use of the method according to the invention.
  • the figures show a non-woven textile 1, composed of intertwined fibers 9.
  • these fibers are made of polypropylene but this condition is not compulsory and any material of this type could be used.
  • the fabric thus metallized should be about as flexible after treatment as before.
  • the vacuum metallization can be done by spraying aluminum in mercury vapors. And we get good results by spraying an amount of 0.5 to lgr./m2 on a polypropylene material of 30 to 80 grJm2.
  • the trap is then completed by applying a second protective coating to the opposite face or lower face 5.
  • the liquid is trapped between the metallized surface and the plastic skin.
  • This skin 8 must be waterproof, flexible, thin and light so that the entire textile trap remains flexible.
  • the two thicknesses are not necessarily contiguous and there may be a space between the two thicknesses , the assembly being carried out by gluing, sewing, or welding or any other means on the edges of the parts.
  • the trap works as follows:
  • the experiment makes it possible to observe that the particles, in contact with a metallized fiber, slip on the fiber and gradually gather around the fiber to form a very fine drop 7, practically invisible to the naked eye. Surprisingly enough, the particles do not extend over the fibers and do not clog the space 4 between the fibers; they approach each other and on the contrary leave the space between the metallized fibers free of liquid.
  • liquid particles are no longer absorbed in these new fibers which are metallized but immediately agglomerate in fine drops around them.
  • this implementation of the trapping process is used for small quantities of liquids.
  • the liquid not absorbed in the thickness of the material meets the film and extends over it without passing through it.
  • the upper surface retains its metallic exterior appearance and flexibility.
  • This implementation is preferably used in the manufacture of protective clothing.
  • the liquid passes through the metallized layer and is partly absorbed in the non-metallized thickness of the textile.
  • this first thickness is sufficient, but in the event of a significant quantity of liquid, a second thickness of textile, untreated, absorbs the excess so that on the lower face 11 of the trap thus formed no trace of liquid can appear, the operator's skin or clothing thus being completely protected.
  • the trapping process is used in particular to produce covers 13 and protective clothing for touch-up operations on bodywork, cars or the like.
  • the houses 13 will be produced so as to trap the paint on its two faces.
  • metallization on the two faces is sufficient to make the protection identical on both sides.
  • the textile can be cut and folded back on itself, for example on the cover 14, the lower face becoming the upper face, and being exposed to projections.
  • the cover panels are equipped with zippers 16 which notably facilitate the masking.
  • the method makes it possible to use a cover which completely covers the vehicle 20.
  • the slides 16 By the slides 16, the panel corresponding to the sheet metal to be painted is opened and the masking is carried out without any particular cover, directly by applying an adhesive tape 15 on the edges of the open panel and on the body thus delimited.
  • the method is preferably used to prevent the particles of liquids from detaching from a material and moving towards a surface which one wishes to protect. But it can find a completely different application: that of being a decorative material; the metallized surface being always free of liquid, the incident light is reflected on it so that the eye does not perceive the fine droplets of liquid agglomerated around the fibers, nor the liquid trapped on the impermeable film; he only sees the metallic aspect.
  • the upper face then takes on the metallic appearance tinged with the pigment of the trapped liquid.
  • Trapping can therefore be used for decoration purposes, or for interior arrangements.
