Definitions

  • the invention relates to a sanitary wash consisting of a microfilament nonwoven fabric with weights per unit area of 60 to 300 g / m 2 .
  • Document EP-A 0 624 676 discloses nonwoven fabrics made of ultrafine fibers and processes for their production from bicomponent fibers.
  • the starting polymers of the bicomponent fibers should have a melting point difference of 30 to 180 ° C and are spun as multi-segment fibers.
  • the bicomponent fibers laid down to form a pile of fibers are subjected to a point calendering in which only the fiber component with the lower melting point is melted and solidified.
  • at least 70% of the nonwoven fabric formed from the multi-segment fibers is split into the ultrafine sub-segment fibers by mechanical action on the fibers.
  • the nonwovens obtained in this way achieve tensile strength values in the longitudinal and transverse directions of up to a maximum of 260 N / 5 cm and can be used as bed linen, absorbent for sanitary products such as handkerchiefs, diapers, padding for sleeping bags, synthetic leather, thermal insulation materials and others.
  • the object of the invention is to provide inexpensive sanitary linen and a method for their production.
  • the object is achieved by a sanitary wash, which consists of a microfilament nonwoven fabric with grammages of 60 to 300 g / m 2 , the nonwoven fabric being melt-spun, stretched and immediately deposited into a nonwoven multicomponent continuous filament with a titer of 1.5 to 5 dtex exists and the multicomponent continuous filaments are optionally split and consolidated at least 80% into micro continuous filaments with a titer of 0.1 to 0.8 dtex after pre-consolidation.
  • no hemming is necessary due to the endless filaments and there is no fraying or fraying.
  • the sanitary laundry is preferably also one in which the nonwoven fabric consists of melt-spun, aerodynamically stretched and immediately deposited multi-component continuous filaments with a titer of 1.5 to 3 dtex and the multi-component continuous filaments are at least 80% micro-continuous filaments with a Titers of 0.1 to 0.3 dtex are split and solidified.
  • the sanitary linen has an isotropic filament distribution in the fleece. It is therefore not necessary to take the machine direction into account when cutting the sanitary linen.
  • the sanitary laundry is preferably also one in which the multi-component continuous filament is a bicomponent continuous filament made of two incompatible polymers, in particular a polyester and a polyamide.
  • a bicomponent filament has good cleavability in micro filaments and has a favorable ratio of strength to basis weight.
  • the sanitary linen according to the invention is wrinkle-free, easy to wash and quick-drying, i.e. easy to care for.
  • the sanitary linen is preferably also one in which the multicomponent filaments have a cross section with an orange or also have a multi-segment structure called "pie", the segments alternately each containing one of the two incompatible polymers.
  • the multicomponent continuous filaments have a cross section with an orange or also have a multi-segment structure called "pie"
  • the segments alternately each containing one of the two incompatible polymers.
  • there is also a "side-by-side" (s / s) segment arrangement of the incompatible polymers in the multi-component continuous filament 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 multi-component continuous filaments and the micro continuous filaments split therefrom favor the ability of the sanitary laundry according to the invention to absorb moisture.
  • the sanitary laundry is preferably also one in which at least one of the incompatible polymers forming the multi-component continuous filament contains an additive, such as color pigments, permanently acting 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, permanently acting antistatic agents and / or additives which influence the hydrophilic or hydrophobic properties in amounts of up to 10% by weight.
  • the sanitary linen which is made of spun-dyed filaments, has a 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.
  • the process according to the invention for producing a sanitary wash consists in spinning, stretching and immediately depositing multi-component continuous filaments from the melt, depositing them immediately into a nonwoven fabric, optionally pre-consolidating them, and solidifying the nonwoven fabric by high-pressure fluid jets, like simultaneously in micro continuous filaments with a titer of 0 , 1 to 0.8 dtex is preferably split with a titer of 0.1 to 0.3 dtex.
  • the sanitary linen thus obtained is very uniform in terms of its thickness, it shows an isotropic thread distribution, has no tendency to delaminate and is characterized by high modulus values.
  • the process for producing the sanitary laundry is advantageously carried out in such a way that the solidification and splitting of the multicomponent continuous filaments takes place in that the optionally pre-consolidated nonwoven fabric is subjected to high-pressure water jets at least once on each side.
  • the sanitary laundry therefore has a good surface and a degree of splitting of the multi-component continuous filaments> 80%.
  • 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 sanitary linen according to the invention is advantageously subjected to a point calendering 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.
  • the sanitary linen produced according to the invention is particularly suitable as towels, bath towels and washcloths or dish towels as well as endless towels or sauna towels due to their care properties such as good washability and low drying time as well as their good moisture absorption capacity, the printability and the haptic design by means of roughing or sanding.
  • example 1
  • a filament pile with a basis weight of 154 g / m 2 is produced from a polyester-polyamide (PES-PA) bicomponent filament and subjected to water jet needling at pressures of up to 250 bar on both sides.
  • the bicomponent continuous filaments have a titer of ⁇ 0.2 dtex after the water jet needling, which leads to a simultaneous splitting of the starting filaments.
  • the nonwoven fabric obtained from super-micro continuous filaments has a water vapor transmission index i mt of 0.45, a short-term water vapor absorption capacity Fj of 0.8 and one

Abstract

La présente invention concerne un linge hygiénique, constitué d'un non-tissé à microfibres, présentant un grammage qui va de 60 à 300 g/m2. Ledit non-tissé est constitué de filaments sans fin à plusieurs composants, filés à chaud, étirés, présentant un titre allant de 1,5 à 5 dtex et directement déposés pour former un non-tissé. Les filaments sans fin à plusieurs composants sont éventuellement séparés et encollés à au moins 80 %, après pré-encollage, afin de former des microfilaments sans fin, présentant un titre allant de 0,1 à 0,8 dtex.
