Definitions

  • the invention relates to protective work clothing consisting of a microfilament nonwoven fabric with weights per unit area of 60 to 300 g / m 2 and a tensile strength of> 150 N.
  • the object of the invention is to provide inexpensive protective work clothing which has a tensile strength of> 150 N and a method for producing it.
  • the object is achieved by protective work clothing which has a microfilament nonwoven with grammages of 60 to 300 g / m 2 and a tensile strength of> 150 N, the nonwoven consisting of melt-spun, stretched and immediately deposited multi-component filaments with a nonwoven there is a titer of 1.5 to 5 dtex and the multicomponent continuous filaments are optionally split and solidified at least 80% into micro continuous filaments with a titer of 0.1 to 0.8 dtex after pre-consolidation.
  • no hemming is required due to the endless filaments and there is no fraying or fraying.
  • Protective work clothing is preferably one in which the nonwoven fabric consists of melt-spun, aerodynamically stretched and immediately stored multi-component continuous filaments with a titer of 1.5 to 3 dtex and the multi-component continuous filaments at least 80% to micro-continuous filaments with a titer from 0.1 to 0.3 dtex are split and solidified.
  • Protective work clothing has an isotropic filament distribution in the fleece. It is therefore not necessary to take machine running into account when cutting the parts of protective work clothing.
  • Protective work clothing is preferably one in which the multi-component continuous filament is a bicomponent continuous filament composed of two incompatible polymers, in particular a polyester and a polyamide. Such a bicomponent filament has good cleavage in micro filaments and brings about a favorable ratio of strength to basis weight. At the same time, because of the polymers used and their filament structure, the protective work clothing according to the invention is wrinkle-free, easy to wash and quick-drying, ie easy to care for.
  • Protective work clothing is preferably one in which the multicomponent continuous filaments have a cross-section with an orange-like or also called “pie” structure, the segments alternately each containing one of the two incompatible polymers.
  • the multicomponent continuous filament is a "side-by-side" (s / s) segment arrangement of the incompatible polymers in the multicomponent continuous filament is also possible, which is preferably used to produce crimped filaments.
  • Such arrangements of the incompatible polymers in the multicomponent filament have proven to be very easy to split.
  • the “pie” segment arrangement in the multicomponent continuous filaments and the micro continuous filaments split therefrom favor the ability of the protective clothing according to the invention to absorb moisture.
  • the protective work clothing is preferably also one in which at least one of the incompatible polymers forming the multicomponent continuous filament contains an additive, such as color pigments, permanent antistatic agents and / or additives which influence the hydrophilic or hydrophobic properties in amounts of up to 10% by weight.
  • an additive such as color pigments, permanent antistatic agents and / or additives which influence the hydrophilic or hydrophobic properties in amounts of up to 10% by weight.
  • the protective clothing made of spun-dyed filaments has very good fastness to washing.
  • the additives can reduce or avoid static charges and improve the moisture transport properties. This also improves washability, i.e. the consumption of detergents is reduced and the drying time is reduced.
  • Protective work clothing consists of spinning multicomponent filaments from the melt, stretching them and laying them down immediately to form a nonwoven, possibly pre-consolidating them and solidifying the nonwovens by high-pressure fluid jets, at the same time in micro- Continuous filaments with a titer 0.1 to 0.8 dtex is split.
  • the protective clothing obtained in this way is very uniform in terms of its thickness, it has an isotropic thread distribution, has no tendency to delaminate and is characterized by high modulus values.
  • the process for producing protective work clothing is advantageously carried out in such a way that the solidification and splitting of the multi-component continuous filaments takes place in that the pre-consolidated nonwoven fabric is subjected to high-pressure water jets at least once on each side.
  • Protective work clothing therefore has a good surface and a degree of splitting of the multi-component continuous filaments> 80%.
  • the protective clothing according to the invention is advantageously subjected to a point calendering in order to increase its abrasion resistance.
  • the split and solidified nonwoven is passed through heated rollers, of which at least one roller has elevations which lead to a selective fusing of the filaments with one another.
  • a method is particularly preferred in which the multicomponent continuous filaments are spin-dyed.
  • the integration of the dyes in the polymer fibers leads to excellent wash fastness.
  • the protective workwear manufactured according to the invention includes, in particular, overalls, smocks, jackets, aprons, trousers and skirts. example 1
  • a filament pile with a basis weight of 154 g / m 2 is produced from a polyethylene terephthalate polyamide (PET-PA) bicomponent continuous filament with a weight ratio of PET / PA66 in the elementary filament of 70/30 and subjected to water jet needling with pressures of up to 230 bar on both sides ,
  • PET-PA polyethylene terephthalate polyamide
  • the bicomponent filaments have a titer of ⁇ 0.2 dtex after water jet needling, which leads to simultaneous splitting of the starting filaments.
  • the work clothing made of continuous micro filaments has a water vapor transmission index i m t of 0.45, a short-term water vapor absorption capacity Fj of 0.8 g / m 2 and a water vapor transmission resistance R et of 3.49 m 2 Pa / W.
  • Thermal resistance R ct is 26.0 10 "3 m 2 K / W.
  • the tensile strength in the machine direction is 330 N and transverse to it 372 N.
