Definitions
- Protective clothing for clean rooms has the function that the products manufactured or processed in these rooms (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) to protect.
- disturbing particles e.g. dust or skin particles, bacteria
- Protective clothing material must retain both the particles permanently released by the human body (skin flakes, hair fragments, bacteria, etc.) and the fiber fragments detached from a textile underwear in order to avoid contamination of the clean room air and thus of the product. Of course, the material itself must not emit any fiber parts or other components in the clean room air.
- the protective clothing material must have a high mechanical strength, in particular have a high tear and abrasion resistance in order to avoid the risk of cracks or holes being formed as a result of external influences or
- the material In order to be able to reuse the protective clothing several times, the material must also withstand the washing or cleaning processes customary in the industry (in some cases sterilization in an autoclave) as undamaged as possible, i.e. resistant to wet mechanical abrasion and pilling as well as being sufficiently dimensionally stable. In addition to the barrier effect and (wet) mechanical resistance, the protective clothing material - especially for
- the material should not become excessively electrostatically charged or should be able to dissipate and dissipate any charges quickly. This is necessary so that, on the one hand, sensitive microelectronic components are not damaged by selective discharges and, on the other hand, no dust particles from the ambient air are attracted, which can accumulate on the material surface and possibly be emitted again later.
- the protective clothing material should also be sufficiently comfortable to wear, that is to say that it should have a textile character with regard to the case, handle and appearance, and be breathable and possibly also heat-insulating in order to avoid excessive sweating or freezing of the wearer.
- Fibers with a titer of less than 1 dtex which are also referred to as “microfibers”, are understood here as “extremely fine”.
- the term “super microfiber” is also used for microfibers with a titer of less than 0.3 dtex.
- the actual protective clothing material is woven from the (textured) microfiber or microfilament yarns.
- conductive threads in the form of a regular pattern, e.g. weave in stripes or plaid arrangement to achieve the required antistatic effect.
- the conductive yarns contain e.g. Core / sheath filaments with a soot or graphite core or sheath or also e.g. Metal fibers or
- Microfibre yarn weave achieved. However, this high weave density and the predominantly surface-parallel filament orientation are unfavorable with regard to the breathability of the material. Few exist Micropores or channels through which water vapor could be transported through the tissue.
- Breathability of the protective clothing material can be achieved by using particle-tight, but water vapor permeable membranes.
- Such "microporous" layers can be on normal density textile
- Materials e.g. be applied by lamination or direct extrusion to obtain a material with a textile character.
- Microfiber nonwovens are an alternative.
- Microfiber nonwovens made from multi-segment or multi-core are limited. Microfiber nonwovens made from multi-segment or multi-core
- Staple fibers which are split into individual microfibers after fleece laying and possibly pre-consolidation using solvents or water jets with a good barrier effect should offer significantly better wearing comfort than the above-calendered microfilament spunbonded fabrics.
- microfiber non-woven fabric to produce a microfiber nonwoven fabric that has an extremely high filling density and thus a good barrier effect.
- this nonwoven fabric lacks softness and heat insulation properties. As a result, the use of
- Water jet bonded nonwovens for the (protective) clothing area are considered limited. Another method is therefore proposed in the cited patent in which the water jet technology is not used.
- Patent document proposed to first thermally weld the nonwoven at certain points before the water jet splitting. This is to prevent the nonwoven from getting caught in the water jet splitting with the sieve belt of the water jet unit and then damaging or even damaging when it is lifted off
- nonwoven fabric made of very fine filaments, which with woven or knitted textiles should have comparable properties.
- the very fine filaments with a titer of 0.005 to 2 dtex are made from melt-spun, crimped or uncurled by means of water jet splits
- the nonwoven fabric obtained in this way can still be used in various ways
- spunbonded nonwovens produced by this process are said to be outstandingly suitable for the production of clothing and other textile products.
- Nonwovens produced by EP patent 97 108 364 are very well suited for the production of clean room protective clothing if they consist of supermicrofilaments with titers less than 0.2 dtex and moreover
- the supermicrofilaments themselves are produced by water jet splitting from multi-component filaments with a titer of less than 2 dtex, which are formed by melt spinning, aerodynamically
- the present invention thus describes a novel one
- Nonwoven material and the process steps for its production The nonwoven meets all the requirements for a reusable material Cleanroom protective clothing material. It is characterized by a high
- Barrier effect a high mechanical resilience and dimensional stability, an efficient antistatic effect and a high level of comfort (breathability and textile character). These favorable properties remain even after repeated washing or
- 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 97 108 364.
- the proportion of the polyester is chosen higher than that of the polyamide, preferably between 60 to 70% by weight. In order to achieve the required antistatic effect, one of the two or
- both polymers with corresponding permanently active, i.e. not washable or washable additives.
- the antistatic effect can e.g. by mixing carbon black or graphite or by adding polymers
- the primary bicomponent filaments have a cross-section with orange-like multi-segment structure (“pie structure”). The segments alternately each contain one of the incompatible, additized polymers. This known filament cross-section has proven to be favorable for the production of the super microfilaments described below.
- the desired high abrasion resistance and low tendency to pilling To achieve the nonwoven fabric, 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 deposited on a moving belt in a random arrangement by means of special units and then pre-consolidated using conventional water jet technology, i.e. mechanically intertwined. Subsequently, the pre-consolidated primary filament fleece is subjected to high pressure water jets on both sides on perforated drums several times, the primary filaments being practically completely divided into their components, i.e. into the individual super microfilaments
- microfiber fleece which, on the one hand, has the required high barrier effect due to its extremely random and intermingled fiber structure, but on the other hand is still sufficiently permeable to water vapor.
- the microfiber nonwoven is used after the water jet splitting and Subsequent drying subjected to a hot air heat setting process under tension.
- the nonwoven is then embossed in a calender with a special engraving roller in order to further increase the 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, the primary filaments being split into the individual segments and these being 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 slightly to approx. 55% for particles> 0.5 ⁇ m or approx. 95% for particles> 1 ⁇ m.
