Definitions
- the invention relates to a substance for protective clothing, namely warning protective clothing, which consists of a fleece and with a coating of luminescent Dye is provided, and a corresponding method for the same Production.
- the object of the present invention is accordingly such a substance and to specify a method for its production, which in addition to a sufficient Fluorescent power also sufficient waterproofness while Has breathability.
- a coating thickness should be as small as be kept possible, both for cost reasons and around a substance to maintain both its breathability and its high wearing comfort regarding softness etc.
- This object is achieved in that the method for Production of a corresponding substance for protective clothing, in which a Nonwoven fabric with a coating with the addition of in particular luminescent Color pigments are provided, the coating after its application mechanically is compressed.
- the invention is based on the finding that the mechanical Compact the layer applied to the nonwoven into the pores of the nonwoven is pressed in and makes these pores impermeable to water, while the passage of water vapor is still possible, so that a Desired breathability remains guaranteed.
- the pores become reduced in size by the pressed-in coating in such a way that by the remaining small pores water droplets due to their surface tension of the coated side cannot penetrate while at the same time Water vapor escaping from the uncoated inside to the outside is not hindered. This leads to the desired breathability.
- the mechanical compression is preferably carried out by calendering or satin. These processes are sufficiently known to the person skilled in the art, so that they are not too big of a problem to handle.
- the coating is preferably applied in several passes.
- Coating in multiple passes can also achieve that with each further pass coating material gets into such pores, that with a previous coat not with the coating compound were wetted.
- luminescent color pigments are in particular fluorescent pigments understood, colloquially also as "Neon colors" are called. These are especially substances that light up by irradiation.
- the pigments used can be their corresponding fluorescence both when irradiated with ultraviolet light or generate with daylight.
- the proposed pigments absorb UV radiation and / or short waves of the visible light spectrum and convert it into visible radiation, which increases the reflection of the color. This then leads to the colors appearing intense and very bright.
- a triazine-sulfonamide-formaldehyde polycondensation resin is particularly suitable with organic dyes as a pigment.
- such Pigments are commercially available e.g. B. by the companies Radiant Color, DayGlo, Whorlee, Sterling u. a. m.
- luminescent pigments are also phosphorescent or self-illuminating pigments understood, the illuminated Radiate light again with a time delay. Also reflective color pigments are recorded here, but not from retro-reflective pigments such as. Glass beads is run out.
- the coating is applied in particular with an air or Shoe squeegee.
- an air or Shoe squeegee but of course there are also others known to the person skilled in the art Application procedure possible, e.g. B. Reverse Roll Coating, Squeegee, Air Knife etc.
- the luminescent pigments are in the process according to the invention introduced in particular in a binder combination, the dispersion-based is constructed.
- Water is therefore preferably used as the solvent, so that there are no problems with MAK values during drying and later use there, which may be exceeded with solvent-containing binders could. This also prevents irritation to the skin or respiratory tract.
- the binder of the coating slip preferably contains at least one of the following components, either individually or in a suitable combination: Acrylate, acrylate ester, polyurethane, polyvinyl acetate, styrene butadiene.
- a cross thread or warp thread fleece in particular made of polypropylene.
- Fleece is reasonably priced and at the same time - in contrast to one Spunbond fleece - sufficiently tear-resistant even in the longitudinal and transverse directions.
- at such a cross thread or warp thread fleece is usually one side somewhat smoother and resembles the appearance of a spunbonded fleece. This side is usually softer. This smooth side points in contrast on the rougher side there is no conspicuous pore structure. Essential is that according to the present invention the rougher side is coated becomes.
