Definitions

  • the invention relates to a method for producing spunbonded nonwovens from spun fibers and / or filaments by blow spinning a melt or a solution of a spinnable polymeric material with the aid of a nozzle head which has one or more nozzle openings and a receiving device.
  • a process for the production of spunbonded nonwovens by spray spinning (blow spinning) of fiber-forming polymers is also known from German published patent application 19 00 265; in this publication it is pointed out that all organic polymers which can be processed by melt spinning or solution spinning can be used for the process as fiber-forming polymers; polyolefins, e.g. Polypropylene and polyethylene, also called cellulose acetate and triacetate, polyamides, polyacetals, polyesters and acrylic polymers.
  • spunbonded nonwovens have a too low tear resistance for use as a carrier material for synthetic leather.
  • the advantage of the measure claimed in claim 2 is that it allows the monofilaments and filament yarns to be applied or introduced in a targeted manner onto or into the mass of the staple fibers and / or filaments forming the spunbonded nonwovens, as a result of which an even better, that is to say even more even distribution of the Monofilaments and filament yarns on or in the mass of the staple fibers and / or filaments and thus on or in the spunbonded fabric can be achieved.
  • spinnable polymeric materials for the purposes of the invention, all those which can be processed by melt spinning or solution spinning (dry spinning) can be used as spinnable polymeric materials; Suitable are therefore, for example, polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, polyamides such as polyamide-6,6 and polyamide-6, cellulose esters such as cellulose-2,5-acetate and triacetate, and acrylic polymers such as polyacrylonitrile.
  • polyolefins such as polyethylene and polypropylene
  • polyesters such as polyethylene terephthalate
  • polyamides such as polyamide-6,6 and polyamide-6
  • cellulose esters such as cellulose-2,5-acetate and triacetate
  • acrylic polymers such as polyacrylonitrile
  • smooth and / or crimped monofilaments and / or smooth and / or crimped filament yarns are applied to the mass of the staple fibers and / or filaments forming the spunbonded nonwovens or are introduced into the mass of the spunbonded fibers and / or filaments.
  • Smooth monofilaments and filament yarns are understood to mean those that have no crimp.
  • Possible crimped monofilaments and filament yarns are, for example, those which have been crimped by false twist crimping, blow nozzle crimping or stuffer box crimping.
  • the monofilaments and filament yarns can be made, for example, from polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, polyamides such as aromatic polyamides, polyamide-6 and polyamide-6,6, cellulose esters such as cellulose-2,5-acetate and triacetate, and Acrylic polymers, such as polyacrylonitrile, exist.
  • polyolefins such as polyethylene and polypropylene
  • polyesters such as polyethylene terephthalate
  • polyamides such as aromatic polyamides
  • polyamide-6 and polyamide-6,6, cellulose esters such as cellulose-2,5-acetate and triacetate
  • Acrylic polymers such as polyacrylonitrile
  • Examples include a smooth polypropylene monofilament 20 dtex f 1, a false twist crimped polyamide 6.6 filament yarn 22 dtex f 5 or a false twist crimped polyamide 6.6, filament yarn 44 dtex f 13.
  • the monofilaments and filament yarns can also have a much lower or higher titer.
  • the monofilaments and filament yarns have a modulus of at least 1 cN / dtex.
  • the module (also referred to as the elasticity or initial module) is obtained from the inclination of the tangent to the first linear part of the tensile stress-strain curve, the tensile strength-related tensile stress on the Y-axis above the strain on the X- Axis is applied.
  • the tensile stress-strain curve is determined by a tensile test according to DIN 53834.
  • the device in FIG. 1 has a nozzle head 1 with nozzle openings 2, a receiving device 3 and deflecting rollers 5.
  • the lateral rollers 5 are laterally so close to the mass 6 of the spunbond fibers and / or filaments emerging from the nozzle openings 2 and forming the spunbonded nonwoven 7 arranged that the supplied via these deflection rollers 5 smooth and / or crimped monofilaments 4 and / or smooth and / or crimped filament yarn 4 by the accompanying the mass 6 of the staple fibers and / or filaments, entrained by the blow spinning and called primary gas stream and carried on the mass 6 of the spun fibers and / or filaments are applied.
  • the device of FIG. 2 has a nozzle head 1 with nozzle openings 2, a receiving device 3 and filament or.
  • the conveying nozzles 8 are the spunbonded fabric to the side of the mass 6 of those emerging from the nozzle openings 2. 7 forming spun fibers and / or filaments arranged.
  • the smooth and / or crimped monofilaments 4 and / or the smooth and / or crimped filament yarns 4 are fed to the mass 6 of the staple fibers and / or filaments ; the pressure of this air or gas is adjusted so that the monofilaments 4 and / or the filament yarns 4 are inflated onto the mass 6 of the spun fibers and / or filaments, i.e. do not penetrate into this mass 6, after which they pass through the mass 6 accompanying the spun fibers and / or filaments, which are entrained by the blow spinning and called primary gas flow.
  • the device according to FIG. 3 has a nozzle head 1 with nozzle openings 2, a receiving device 3 and deflecting rollers 5.
  • the deflecting rollers 5 are arranged below the nozzle head 1 in the middle between two adjacent nozzle openings 2, so that the smoothly fed through these deflecting rollers 5 and / or crimped monofilaments 4 and / or smooth and / or crimped filament yarns 4 are brought into the interior of the mass 6 of the spun fibers and / or filaments emerging from the nozzle openings 2 forming the spunbonded nonwoven 7, after which they pass through the mass 6 of the spun fibers and / or accompanying filaments which are entrained by the gas spinning and called primary gas flow.
  • the device according to FIG. 4 has a nozzle head 1 with nozzle openings 2, a receiving device 3 and filament or.
  • the conveying nozzles 8 are arranged to the side of the mass 6 of the spun fibers and / or filaments emerging from the nozzle openings 2 and forming the spunbonded nonwoven 7.
  • the smooth and / or crimped monofilaments 4 and / or the smooth and / or crimped filament yarns 4 are fed to the mass 6 of the staple fibers and / or filaments ; the pressure of this air or gas is adjusted so that the monofilaments 4 and / or the filament yarns 4 are blown into the interior of the mass 6 of the staple fibers and / or filaments, after which they pass through the mass 6 of the staple fibers and / or filaments accompanying gas stream caused by blow spinning and called primary gas stream.
  • Polypropylene with a melt index at 230 ° C / 2.16 kg of 13 g / 10 min, a density at 23 ° C of 0.902 g / cm 3 and a melting range of 165-170 ° C was melted and using the nozzle head 1, which was similar to that according to German Patent 25 50 463, spun (blow-spun) through the nozzle openings 2 to form spun fibers and filaments which had an average diameter of 1.0 ⁇ m.
  • the staple fibers and filaments were formed into a spunbonded fabric by being deposited on the holding device 3, which consisted of a rotating drum.
  • the fleece obtained had a weight per unit area of 150 g / m 2 .
  • Example 4 The device according to FIG. 4 was also used for this example. The difference compared to Example 1, however, was that one of the filament or. Filament yarn feed nozzles 8, which was comparable to the nozzle described in the German utility model 73 06 184, was in operation.
  • Example 2 Under the same conditions as in Example 1, the same polymer was melted and spun (blow spun) with the aid of the nozzle head 1 through the nozzle openings 2 to form spun fibers and filaments which had an average diameter of 1.0 ⁇ m.
  • a smooth polyamide-6,6 filament yarn 44 dtex f 13 with a modulus of 29.3 cN / dtex was fed to the mass 6 of the staple fibers and filaments, namely at an angle of 45 ° to the flow direction of this mass 6; the pressure of the air at which the feed nozzle 8 was operated was adjusted so that the polyamide 6,6-filament yarn was blown into the interior of the mass 6 of the staple fibers and filaments.
  • the polyamide 6,6 filament yarn was entrained by the primary gas flow accompanying mass 6 of the staple fibers and filaments, as in example 1 a hot air flow, and was distributed tangled within mass 6 of the staple fibers and filaments.
  • a spunbond fabric was formed by depositing the mass 6 of the staple fibers and filaments with the polyamide-6,6 filament yarn on the receiving device 3, which consisted of a rotating drum.
  • the fleece obtained had a weight per unit area of 165 g / m 2 .
  • Example 1 The same device and the same polymer as in Example 1 were used to carry out this example.
  • the conditions differed only from those of Example 1 in that somewhat more polypropylene melt per unit time was conveyed through the nozzle openings 2 and the pressure of the mass 6 of the spun fibers and filaments accompanying primary gas flow - as in example 1 of a hot air flow - was slightly increased; thus spun fibers and filaments with an average diameter of 1.0 ⁇ m were blow-spun.
  • the staple fibers and filaments were formed into a spunbonded fabric by being placed on the holding device 3 —the same drum rotating at the same speed as in Example 1.
  • the fleece obtained had a basis weight of 170 g / m 2 , a thickness of 6 mm and an air passage of 600 m 3 / m 2 . h at a differential pressure of 490.35 Pa.
  • Example 2 The same device and the same polymer as in Example 1 were also used for this example. The conditions corresponded to those of Example 3 except for the fact that one of the filament or. Filamentgam thoroughdüsen 8, which was comparable to the nozzle described in the German utility model 73 06 184, was in operation.
  • the fleece obtained had a weight per unit area of 251 g / m 2 and a thickness of 15 mm.
  • the measurement of the air passage of this fleece resulted in a value of 1,200 m 3 / m 2 . h at a differential pressure of 490.35 Pa.
  • Example 4 was repeated, with the difference, however, that with the aid of the one delivery nozzle 8 instead of the false twist-crimped polyamide 6.6 filament yarn 22 dtex f 5, a false twist crimped polyamide 6.6 filament yarn 44 dtex f 13 with a modulus of 24 cN / dtex was blown into the interior of mass 6 of the staple fibers and filaments, again at an angle of 45 ° to the direction of flow of this mass 6.
  • This polyamide-6,6 filament yarn was also formed by the primary gas flow accompanying mass 6 of the staple fibers and filaments 44 dtex f 13 entrained and distributed tangled within the mass 6 of the staple fibers and filaments.
  • the spunbonded fabric removed from the rotating take-up drum 3 had a basis weight of 230 g / m 2 and a thickness of 22 m.
  • the measurement of the air passage of this fleece resulted in a value of 1,800 m 3 / m 2 h at a differential pressure of 490.35 Pa.
  • the filament or. Filamentgam beatingdüsen 8 which were arranged to carry out Examples 2, 4 and 5, also be arranged pivotably.
