Definitions

  • the invention relates to protective clothing made of a multilayer textile, wherein a microporous, high-density, but water-vapor-permeable inner layer is arranged between two layers of a PP spunbonded fabric.
  • Such a three-layer textile is known.
  • the invention has for its object to improve the comfort of such a textile.
  • Claim 1 initially and essentially provides that the inner layer is formed by a meltblown and is hydrophilic.
  • the inner layer is preferably made hydrophilic in such a way that it can absorb 500-600%, preferably even up to 800%, of its own weight in liquid.
  • the advantage of this textile is the possibility of temporarily storing liquid. This increases comfort.
  • the textile can be used for protective clothing that is intended to prevent the entry of liquids.
  • water vapor can escape through the microporous film formed by the meltblown.
  • the hydrophilic finishing of the middle layer is done via masterbatches. Daber becomes an additive in granu latform added. Which contains an additive substance, for example a pigment or a hydrophilic chemical.
  • This masterbatch is added to the main material in the extruder.
  • Spraying equipment is also conceivable.
  • suitable chemicals are applied to the microporous inner layer.
  • the liquid stored in the inner layer can be released into the environment in a controlled manner.
  • the textile preferably has a fourth, outer microporous film.
  • This microporous film can be made of polypropylene or polyethylene.
  • the two spunbonded webs that hold the meltblown between them are made of polypropylene.
  • the storage function that forms the inner layer means that the
  • Sweating water vapor which cannot immediately penetrate through the textile, does not condense on the inside of the textile, but is absorbed by the inner layer. The water vapor is then gradually released. There is only a small amount of evaporative cooling. The release of moisture from the inner layer performing the buffer function takes place through the outer layer. This can be water-repellent. This increases the usability of the textile as protective clothing, since it does not absorb splash water or other liquids applied from the outside but repels it.
  • the textile according to the invention has the following three-layer structure:
  • the meltblown consists of polypropylene and is made hydrophilic by spraying.
  • the spunbonded fabric and the meltblown it is also possible for the spunbonded fabric and the meltblown to be made of polyethylene.
  • Sweat transport Fi 18 g / m 2 h mbar
  • Sorption rate of water in the textile 4.2 parts (wetting index)

Abstract

L'invention concerne un vêtement de protection constitué d'une matière textile multicouche. Selon ladite invention, une couche intérieure microfine, de haute densité mais perméable à la vapeur d'eau, est placée entre deux couches d'un nontissé de polypropylène ; la couche intérieure formée par fusion-soufflage est hydrophilisée et cette couche peut absorber 500 à 600 %, de préférence jusqu'à 800 % de son poids en liquide.
