Definitions
- the invention relates to sleepwear consisting of a microfilament nonwoven fabric with basis weights of 70 to 150g / m 2 and a particle retention capacity> 90% for particle particles ⁇ 0.5 ⁇ m.
- anti-allergenic coverings are known in which a polyurethane layer is laminated onto a carrier material.
- the polyurethane layer is said to give the material a pore size of ⁇ 10 ⁇ m with simultaneous water vapor permeability.
- the invention has set itself the task of providing inexpensive sleepwear that has a high particle retention capacity at a low weight and a method for its production.
- the object is achieved by sleepwear, which consists of a nonwoven fabric with basis weights of 70 to 150 g / m 2 and a particle retention capacity> 90% for particle particles ⁇ 0.5 ⁇ m, the nonwoven fabric being melt-spun, stretched and immediately deposited into a nonwoven fabric Multicomponent continuous filaments with a titer of 1.5 to 5 dtex exist 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.
- sleepwear with a comparatively low weight, has a particle retention capacity> 90% for particle particles ⁇ 0.5 ⁇ m and is therefore particularly suitable as allergy-free sleepwear for house dust mites and their secretions.
- the sleepwear is preferably one in which the nonwoven fabric consists of melt-spun, drawn and immediately deposited multi-component continuous filaments with a titer of 2 to 3 dtex, and the multi-component continuous filaments are at least 80% micro-continuous filaments with a titer of 0 , 1 to 0.3 dtex are split and solidified.
- the sleepwear 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.
- the sleepwear is preferably one in which the multicomponent continuous filaments have a cross section with an orange-like or also called “pie” multisegment structure, the segments alternately each containing one of the two incompatible polymers.
- the multicomponent continuous filaments a “side-by-side” (s / s) 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 continuous filament have proven to be very easy to split.
- the sleepwear 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 sleepwear made of spun-dyed fibers has a very good fastness to washing. Furthermore, the additives can reduce or avoid static charges and improve the moisture transport properties.
- the sleepwear is preferably also one that is point calendered. Such a design of the surface improves the abrasion resistance.
- the process according to the invention for producing a sleepwear consists in spinning multicomponent continuous filaments from the melt, stretching them and laying them down immediately to form a nonwoven fabric, pre-consolidating them and solidifying the nonwoven fabric by high-pressure fluid jets, as in micro-continuous filaments with a titer of 0 , 1 to 0.8 dtex is split.
- the sleepwear obtained in this way is very uniform in terms of its thickness and has an isotropic thread distribution no tendency to delaminate and is characterized by high module values.
- the process for producing the sleepwear 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 sleepwear 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 abrasion resistance of the sleepwear according to the invention is improved in that the micro-continuous filaments on the surfaces of the nonwoven fabric are spot welded to one another by a thermal calendering process.
- the solidified non-woven fabric, which is split into micro-continuous filaments, is passed through heated rollers which have elevations and at these points lead to a fusion of the micro-continuous filaments with one another.
- the sleepwear according to the invention is particularly suitable as bed linen and bed sheets for allergy sufferers against house dust mites and their secretions.
- the sleepwear according to the invention has good water absorption and water drainage capacity, which manifests itself in corresponding values for water vapor permeability and short-term water vapor absorption capacity or water vapor resistance. 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 0.1 to 0.8 dtex after the water jet needling, which leads to a simultaneous splitting of the starting filaments.
- the sleepwear has a water vapor transmission index i m of 0.45, a short-term water vapor absorption capacity F, of 0.8 and one
