Definitions

  • Protective clothing for clean rooms has the function that is in these rooms manufactured or processed products (e.g. microelectronic parts, Pharmaceuticals, optical glass fibers) before humans as a "source” for the Emission of disturbing particles (e.g. dust or skin particles, bacteria) protect.
  • manufactured or processed products e.g. microelectronic parts, Pharmaceuticals, optical glass fibers
  • disturbing particles e.g. dust or skin particles, bacteria
  • the Protective clothing material must be both that of the human body permanently released particles (skin flakes, hair fragments, bacteria, etc.) as well as those replaced by textile underwear Retain fiber fragments to prevent contamination of the clean room air and thus avoiding the product. Of course, the material also no fiber parts or other components in the clean room air emit.
  • Protective clothing material has a high mechanical strength, in particular have a high tear and abrasion resistance to the Risk of cracks or holes forming as a result of external influences or to minimize normal wear and tear.
  • the material must also industry-standard washing and cleaning processes (partly sterilization in the Autoclaves) survive as undamaged as possible, i.e. resistant to wet mechanical abrasion and pilling as well as sufficient dimensional stability his.
  • the protective clothing material must be particularly robust - especially for use in cleanrooms of the microelectronics industry - an antistatic Have an effect, i.e. the material should stand out from the inevitable Do not subject electrostatic friction to excessive friction or any potential wear Can quickly dissipate and dissipate charges. This is necessary so on the one hand, sensitive microelectronic components not through selective Discharges damaged and on the other hand no dust particles from the Ambient air attracted to the material surface enrich and possibly be re-emitted later.
  • the protective clothing material should also be sufficient have a high level of comfort, i.e. a possible textile character regarding the case, Have a handle and look, as well as being breathable and possibly also heat-insulating to avoid excessive sweating or freezing of the wearer.
  • microfibers or - are made from polymeric raw materials filaments spun. These are then processed into yarns, which possibly go through a subsequent texturing process. From the (Textured) microfiber or microfilament yarns will eventually actual protective clothing material woven. In the weaving process, additionally conductive game in the form of a regular pattern, e.g. in strips or Weave check pattern to achieve the required antistatic effect to reach.
  • the conductive games contain e.g. Core / sheath filaments with soot or graphite-containing core or jacket or also e.g. Metal fibers or metallized filaments.
  • the required barrier function and the high (wet) mechanical Resilience is due to an extremely dense and regular Microfibre yarn weave achieved. This high weaving density and the predominantly surface-parallel filament orientation is however in view adversely affecting the breathability of the material. Few exist Micropores or channels through or through which water vapor is transported through the tissue.
  • the problematic combination of properties of barrier effect and Breathability of the protective clothing material can be determined by the Use of particle-tight but water vapor permeable membranes to reach.
  • Such "microporous" layers can be on normal density textile Materials e.g. applied by lamination or direct extrusion, to get a material with a textile character.
  • microfiber nonwovens are an alternative.
  • Microfiber nonwovens made from multisegment or multicord staple fibers, which after the fleece laying and possibly pre-consolidation split into individual microfibers using solvents or water jets with a good barrier effect should be a significantly better one Comfort than the above offer highly calendered microfilament spunbonded webs.
  • EP-A 0 624 676 e.g. described a procedure how to can produce a microfiber nonwoven fabric by water jet splitting extremely large filling density and thus also good barrier effect.
  • this Nonwoven fabric lacks softness and heat insulation properties. Accordingly, the use of hydroentangled nonwovens for considered the (protective) clothing area to be limited.
  • Another patent is therefore proposed in which the Water jet technology is not used.
  • Patent specification suggested selectively select the nonwoven in front of the water jet chips to be thermally welded. This is to prevent the Nonwoven fabric for water jet splitting with the screen belt of the water jet unit hooked and then damaged or even destroyed when lifting. On the other hand, this is intended to achieve a higher degree of fiber division, which should result in improved barrier and tactile properties.
  • the present invention thus describes a novel method for the production of nonwoven material.
  • the nonwoven meets all requirements of a reusable cleanroom protective clothing material. He is characterized by a high barrier effect, a high mechanical Resilience and dimensional stability, an efficient antistatic effect as well as a high level of comfort (breathability and textile character). These favorable properties remain even after repeated industry-standard washing and cleaning processes (up to 30 cycles) in received sufficient scope. The sum of these properties was hitherto not attainable with a nonwoven fabric with split fine filaments considered.
  • the nonwoven fabric consists of supermicrofilaments with a titre of less than 0.2 dtex, which are produced from uncrimped primary filaments with a titer of 1.5 to 2 dtex.
  • Bicomponent multisegment filaments made of two incompatible polymers, in particular polyester and polyamide, are preferably used as primary filaments. This combination is known, in this respect reference is made to EP-A 0 814 188.
  • the proportion of the polyester is chosen to be higher than that of the polyamide, preferably between 60 to 70% by weight.
  • one of the two or both polymers is provided with corresponding permanently active additives, ie additives which cannot be washed off or washed out.
  • the antistatic effect can be achieved, for example, by mixing in carbon black or graphite or by adding polymers with a highly hydrophilic character or polymers with (semi-) conductive properties, possibly with the addition of compatibilizers.
  • the primary bicomponent fitaments have a cross-section with an orange-like multi-segment structure ( " pie structure").
  • the segments alternately contain one of the incompatible, additized polymers.
  • This filament cross-section which is known per se, has proven to be favorable for the production of the super microfilaments described below.
  • the primary filaments are subjected to a further drawing and tempering process after the usual aerodynamic drawing ( " hot-channel stretching").
  • the primary filaments produced in this way are created using special aggregates random arrangement placed on a moving belt and then pre-consolidated using conventional water jet technology, i.e. mechanically intertwined. Then the pre-consolidated Primary filament fleece on perforated drums several times on both sides High pressure water jets acted on, the primary filaments being practical completely in its components, i.e. into the individual super microfilaments disintegrate and these are simultaneously swirled together extremely homogeneously.
  • This process step creates a microfiber fleece, which is due to its extremely random and turbulent fiber structure on the one hand has the required high barrier effect, but on the other hand is still sufficient is permeable to water vapor.
  • the microfiber nonwoven fabric is subjected to a hot-air thermosetting process after tensioning after the water jet splitting and subsequent drying.
  • the nonwoven is then embossed in a calender with a special engraving roller in order to further increase dimensional stability and abrasion resistance.
  • the finished nonwoven has a basis weight of 80 to 150 g / m 2 , preferably 95 to 115 g / m 2 .
  • a nonwoven fabric with a basis weight of 95 g / m 2 with a uniform thickness of bicomponent filaments consisting of 70% poly (ethylene terephthalate) and 30% poly (hexamethylene adipamide) is produced.
  • the primary filaments have a titer of 1.6 dtex and contain 16 segments, which are alternately made up of polyester or polyamide.
  • the melt-spun filaments are stretched aerodynamically, placed randomly on a belt and subjected to a water jet treatment in which the filaments are pre-consolidated.
  • the pre-consolidated fleece is then treated with high pressure water jets, whereby the primary filaments are split into the individual segments and these are further entangled.
  • the water jet splitting is carried out several times from both sides of the nonwoven.
  • the resulting super microfilaments have an average titer of 0.1 dtex and are uncrimped.
  • the fleece is then dried and embossed calendered.
  • the nonwoven fabric produced in this way has a filter efficiency of approx. 60% for particles ⁇ 0.5 ⁇ m or approx. 98% for particles ⁇ 1 ⁇ m. After 30 washes with a standard detergent at 40 ° C, the filter efficiency drops only insignificantly to approx. 55% for particles ⁇ 0.5 ⁇ m or approx. 95% for particles ⁇ 1 ⁇ m.
