- the fiber or filament raw materials are selected according to the desired chemical or physical properties, for example with regard to their colorability, chemical resistance, their
- Thermoformability their Schmutzing- or their adsorption capacity.
- the modulus and force-strain properties of the fibers or filaments are u. a.
- the material properties which can be controlled by the choice of the degree of crystallization and / or orientation and the cross-sectional geometry to the bending stiffness, the power consumption or the specific
- the sum of the textile-physical properties of the fibers or filaments forming a textile fabric is also controlled by the weight per unit area.
- cleaning wipes need a variety of
- microfiber nonwovens should have both a long service life and good handleability, especially when soaking, Wringing and wiping, a good cleaning efficiency, a good resistance to mechanical wear and / or a specific water balance.
- One way to combine different properties in a cleaning fabric is to combine different types of fibers with one another when selecting the type of production of the fabric (for example, as a woven or knitted fabric or as a nonwoven fabric).

- microfiber nonwovens are disadvantageous in that their durability, especially with frequent washing in industrial washing cycles, is limited, as reflected, for example, in a hole formation in the nonwovens occurring after about 200 industrial washing cycles.
- Nonwovens are theoretically improved because the chemical and mechanical stability of the individual fibers or filaments increases with their thickness. However, this comes at the expense of the use characteristics.

- Appearances such as dyeing or printing.
- microfiber composite sheet having a particularly homogeneous structure can be obtained when the nonwoven fabric is treated by exposure to temperature and / or pressure, preferably by calendering at a temperature of 160 to 220 ° C, preferably 180-200 ° C and / or a line pressure of 20 to 80 N / mm is pre-consolidated.
- the microfiber composite sheet according to the invention is subjected to a point calendering to increase its abrasion resistance.
- the split and solidified microfiber composite sheet is passed through heated rolls, at least one roll of which has elevations, which lead to a selective fusion of the filaments with each other.
- the composite filaments are dyed by spin dyeing.
- microfiber composite sheet according to the invention is finished by a coating or lamination process. However, at least one of the outer layers A remains there.
- 1 is a schematic view of the cross section of a
- cleaning fabric comprising a microfiber composite sheet comprising a layer A comprising a fiber component in the form of composite filaments partially split into elementary filaments and solidified, a layer B disposed on the first layer A, the layer B has an open-pored pore structure with an average pore size of more than 500 pm and wherein the elementary filaments of the first layer A, the pores of the layer B proportionately penetrate and are entangled in the pores of the layer B.
- cleaning text according to the invention comprising a microfibre
- a composite sheet comprising two outer layers A, each comprising a fiber component in the form of composite filaments partially split into elementary filaments and are solidified, a layer B between the two layers A is arranged, wherein the layer B has an open-pored pore structure with an average pore size of more than 500 pm and wherein the elementary filaments of the two layers A penetrate the pores of the layer B proportionally and with the elementary filaments of the middle layer B are devoured.
- FIG. 1 shows a schematic view of the cross section of a
- Fiber component in the form of melt-spun and nonwoven composite filaments which are at least partially split into elementary filaments 3 having an average titer of less than 1 dtex, and solidified.
- a layer B 4 is arranged, wherein the layer B 4 has an open-pored pore structure with an average pore size of more than 500 pm and wherein the elementary filaments 3 of the layer A 2 penetrate the pores of the layer B 4 proportionally and are entangled in the pores 5 of the layer B 4.
- Figure 2 shows a schematic view of the cross section of a
- It has two outer plies A 2, each comprising a fiber component in the form of composite filaments partially split into elementary filaments and solidified, a ply B 4 between plies A 2 wherein the layer B has an open-pored pore structure with an average pore size of more than 500 pm and wherein the Elementary filaments of the two layers A 2, the pores 5 of the layer B 4 proportionately penetrate and with the elementary filaments 3 of the middle layer B
- FIGS. 3 and 4 each show RE images of the cross section of a
- FIG. 5 shows a SEM image of the top view of a device according to the invention
- a layer composite ABA is produced.
- This filament Viieslagen be deposited with an average thickness of 0.02 mm to 0.03 mm on 16 consecutively connected spinnerets.
- 8 thin layers are deposited continuously on a belt over the first 8 nozzles.
- the thin nonwovens are thereby produced by composite filaments which consist of 32 elementary filaments and have a titer before splits of 1.6 dtex and a polymer ratio of PET to PA6 of 70/30.
- a web of the layer B is continuously fed, preferably in the width of the deposited thin nonwovens.
- the layer B here consists of a viscose fiber nonwoven (145 g / m 2 ), vorvemadelt only slightly two-sided. The underside of layer B is thus deposited on the first 8 thin layers.
- the thin layers 9, 10, ... to 16 are placed on the top of the layer B successively.
- the entire composite layer is first driven through a needle chair and pre-consolidated with a few (about 20) stitches / cm 2 and then driven through a water jet system, with the needling of all three layers and simultaneous splitting of the upper and lower water jet beams alternately Composite filaments in the layers A is made.
- the elementary filaments of the first and second layers A at least partially penetrate the pores of the layer B and engulf with the filaments of the respective other layer A and / or the pores of the layer B.
- the layer B is formed by a thin (eg 5 mm thick) foam structure.
- This open-pored foam structure is provided as rolled-up web material.
- a thin layer A of unsplit composite filaments having a weight per unit area of 30 g / m 2 is now applied to one side and loosely connected to the foam web by individual adhesive dots.
- the two-ply composite is driven through a water-jet system in which the HE needling takes place on one side, and only from the side of the composite filaments of the layer A, which are split and devoured simultaneously in the pores of the open-pore foam structure.
