Definitions
- the invention relates to a thermal nonwoven fabric, consisting of a microfilament nonwoven fabric with surface weights of 60 to 300 g / m 2 and a tensile strength> 150 N.
- the invention has set itself the task of providing inexpensive thermal nonwoven fabric that has a tensile strength> 150 N and a method for its production.
- the object is achieved by a thermal nonwoven fabric which consists of a microfilament nonwoven fabric with basis weights of 60 to 300 g / m 2 and a tensile strength of> 150 N, the microfilament nonwoven fabric being made of melt-spun, stretched and immediately deposited into a nonwoven multicomponent Continuous filaments with a titer of 1.5 to 5 dtex and the multicomponent continuous filaments are split and consolidated at least 80% into micro continuous filaments with a titer of 0.1 to 1.0 dtex after optionally pre-consolidation.
- no hemming is necessary due to the endless filaments and there is no fraying.
- the thermal nonwoven fabric is preferably one in which the nonwoven fabric consists of melt-spun, aerodynamically stretched, and multi-component continuous filaments with a titer of 1.5 to 3 dtex, which are immediately deposited to form a nonwoven fabric, and the multi-component continuous filaments, if appropriate after prebonding, are at least 80% microfiber - Continuous filaments with a titer of 0.1 to 0.8 dtex are split and solidified.
- the thermal nonwoven has an isotropic filament distribution in the nonwoven. It is therefore not necessary to take the machine direction into account when cutting the thermal nonwoven.
- the thermal nonwoven is preferably 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 cleavage in micro filaments and brings about a favorable ratio of strength to basis weight.
- the thermal nonwoven according to the invention is wrinkle-free, easy to wash and quick-drying, ie easy to care for.
- the thermal nonwoven 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 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 segment arrangements of the incompatible polymers in the multicomponent continuous filament have proven to be very easy to split.
- the thermal nonwoven has a very good thermal insulation capacity in relation to the thickness and / or the weight, so that soft and warm winter clothing can be produced in particular by subsequent treatment steps such as roughening or sanding.
- the thermal nonwoven is preferably also one in which at least one of the incompatible polymers forming the multicomponent continuous filament is an additive, such as color pigments, permanently acting antistatic agents, fungicides, bactericides, acaricides and / or additives which influence the hydrophilic or hydrophobic properties in amounts of up to 10% by weight , contains.
- the thermal nonwoven fabric made of spun-dyed fibers has very good fastness to washing. Furthermore, the additions can reduce or avoid static charges and improve the moisture transport properties.
- the thermal nonwoven has very good care properties with regard to its washability and a short drying time.
- the process according to the invention for the production of thermal nonwoven fabric consists in that multicomponent continuous filaments are spun from the melt, stretched and deposited immediately to form a nonwoven fabric, pre-consolidation is carried out and the nonwoven fabric is consolidated by high pressure fluid jets as in micro continuous filaments with a titer of 0 ,1 to 1.0 dtex, preferably in micro continuous filaments with a titer of 0.1 to 0.8 dtex, is split.
- the thermal nonwoven fabric 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 distinguished by high modulus values.
- the process for producing the thermal nonwoven is 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 is subjected to high-pressure water jets at least once on each side.
- the thermal nonwoven thus 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 filaments leads to excellent wash fastness.
- the thermal nonwoven fabric produced according to the invention is used in particular for the production of inner pockets, inner lining materials or outer fabrics. It is also suitable as an insert for padding or padding.
- a filament pile with a basis weight of 120 g / m 2 is produced from a polyester-polyamide (PES-PA) bicomponent filament and subjected to water jet needling at pressures of up to 230 bar on both sides. After the water jet needling, which leads to simultaneous splitting of the starting filaments, the bicomponent filaments have a titer of 1.0 dtex.
- the nonwoven fabric made of continuous micro filaments has a water vapor transmission index i mt of 0.56.
- the heat insulation ability expressed by the thermal resistance R ct is 42.5 10 "3 m 2 K / W and the water vapor resistance R et is 4.58 m 2 Pa / W.
