Definitions

  • the invention relates to a high-strength lightweight nonwoven fabric made of spunbonded nonwoven, which comprises at least one layer of melt-spun synthetic filaments which are solidified by means of high-energy water jets. Furthermore, the invention relates to a method for producing such a nonwoven fabric and its use.
  • the object of the invention is to provide a high-strength, lightweight nonwoven fabric made of spunbonded fabric, which is characterized not only by a high strength but also by a high initial modulus.
  • a high initial modulus reduces the susceptibility to initial distortion and the resulting spread in the usual industrial processing steps.
  • a high-tenacity spunbond nonwoven fabric comprising at least one layer of melt-spun synthetic filaments solidified by high-energy water jets, it is provided that it contains a thermally activatable binder which is in the form of at least one thin layer made of melt-spun filaments.
  • the initial compliance manifests on a force-strain diagram as a low initial modulus.
  • a longitudinal distortion associated with a corresponding width entry This complicates or sometimes even prevents the use of such water jet solidified spunbonded fabrics.
  • This high number of fine spunbond filaments bonded together by the above-mentioned additional bonding points contributes to the nonwoven fabric having high modulus values and dimensional stability which is sufficient for further processing.
  • no additional measures for dimensional stabilization such as, for example, a tension control, are necessary during further processing. It is believed that this effect u. a. is also due to the fact that a part of the binder is carried by the high-energy water jets even into the deeper layers of the nonwoven layer into and forms binding points there.
  • a nonwoven fabric according to the invention may be composed of one or else several layers of spunbonded fabric and binder. It is also possible to provide other additional layers as far as they are meaningful for the respective application.
  • low-melting thermoplastic polymers are suitable as binders, preference being given to those thermoplastic polymers whose melting point is sufficiently lower than that of the spun-bonded nonwoven filaments is.
  • the melting temperature should be at least 10 ° C, more preferably at least 20 ° C below the melting temperature of the spunbond filaments so that they are not damaged during thermal activation.
  • the low-melting thermoplastic polymers preferably also have a broad softening range. This has the advantage that the thermoplastic polymer used as a binder can be activated even at lower temperatures than at its effective melting point. From the technological point of view, the binder does not necessarily have to be completely fused, but it is sufficient that it is sufficiently softened and thus adheres to the filaments to be bound. In this way, one can adjust the degree of bonding between the spunbond filaments and the binder in the activation phase.
  • the low-melting thermoplastic polymer preferably consists essentially of a polyolefin, in particular polyethylene, a copolymer comprising a substantial proportion of polyethylene, polypropylene, a copolymer comprising a substantial proportion of polypropylene, a copolyester, in particular polypropylene terephthalate and / or polybutylene terephthalate, of a polyamide and / or a copolyamide.
  • the weight proportion of the low-melting polymer based on the total weight of the nonwoven fabric is preferably greater than or equal to 7%. If the proportion of hot melt adhesive is too low, the initial module gain will be too low and may not be sufficient for future use.
  • the weight fraction is preferably between 9 and 15% by weight. When exceeding 15% by weight, the negative influence of the excessive number of strong adhesive bonds on the tear propagation resistance may possibly prevail.
  • the low-melting polymer may be in the form of fibers or fibrils, for example.
  • biko-fibers can be used as fibers, the low-melting component representing the thermally activatable binder.
  • the present invention enables the use of low denier filaments of spunbonded filaments. Even with low basis weights this good strength and sufficient coverage is achieved.
  • the fiber titer is between 0.7 and 6 dtex. Fibers with a titer between 1 and 4 dtex have the particular advantage that they ensure both good surface coverage at medium basis weights and have sufficient overall strengths.
  • a nonwoven fabric according to the invention preferably comprises filaments of polyester, in particular polyethylene terephthalate, and / or of a polyolefin, in particular polypropylene. These materials are particularly suitable because they are made from bulk raw materials that are available everywhere in sufficient quantity and quality. Both polyester and polypropylene are well known in fiber and nonwoven fabric manufacture for their utility.
  • PEN polyethylene naphthalate
  • Insert PET and PEN Compared to PET, PEN is characterized by a higher melting point (about + 18 ° C) and a higher glass transition temperature (about + 45 ° C).
  • spunbonded nonwovens ie the spinning of synthetic filaments of various polymers, including polypropylene or polyester, as well as their storage to a random web on a carrier state of the art.
  • Large-scale facilities with widths of 5 m and more can be purchased from several companies. You can have one or more spin systems (spin bars) and set to the desired performance. Hydroentangling systems for hydroentanglement are also state of the art. Even such systems can be provided in large widths by several manufacturers. The same applies to dryers and winders.
  • the thermally activatable binder can be applied by various methods, e.g. B. by powder, even in the form of a dispersion.
  • the binder is applied in the form of fibers or fibrils by means of a meltblown or an airlaying process. These methods are known and widely described in the literature.
  • Meltblown and airlaying processes have the particular advantage that they can be combined as desired with spinning systems for spunbonded filaments.
  • the hydroentanglement should, as from the DE 198 21 848 C2 known to be carried out so that a specific longitudinal strength of preferably 4.3 N / 5cm per g / m 2 of the basis weight and a starting modulus measured in the longitudinal direction as a stress at 5% elongation of at least 0.45 N / 5cm per g / m 2 Surface mass can be achieved. This ensures a sufficient strength of the spunbonded fabric and a sufficiently good distribution of the binder in the spunbonded layer.
  • activation is to be understood as the generation of binding points by means of the binder, for example by melting or melting a low-melting polymer used as a binder.
  • Both the drying and the thermal treatment for activation are to be carried out at temperatures which are so low that damage to the spunbond filaments, for example by melting or melting, is reliably avoided.
  • the drying and the thermal activation of the binder preferably take place in one process step.
  • the drying temperature should be adjusted in the final phase to about the melting temperature of the low-melting polymer and optimized depending on the results.
  • the entire melting behavior of the binder is taken into account.
  • the nonwoven fabric according to the invention is suitable for applications in the technical field, in particular as a coating carrier, reinforcing or reinforcing material.
  • the experimental plant for the production of spunbonded nonwovens had a width of 1200 mm. It consisted of a spinneret extending across the entire width of the plant, two blowing walls arranged opposite and parallel to the spinneret, a subsequent withdrawal nip extending in the lower area to a diffuser and forming a web formation chamber.
  • the spun filaments formed a uniform fabric, a spunbonded fabric, on a collection tape sucked from below in the web formation region. This was compressed between two rolls and rolled up.
  • the preconsolidated spunbonded web was unrolled on a test rig for hydroentanglement. Using an airlaying system, a thin layer of short binder fibers was applied to its surface, and the two-layer sheet was subsequently treated with a variety of high-energy water jets, thereby hydroentangled and solidified. At the same time, the binder was distributed in the fabric. Subsequently, the consolidated nonwoven web was dried in a tumble dryer, with the temperature in the end zone of the dryer adjusted to activate the binder fibers and cause additional bonding
  • a spunbonded nonwoven fabric was made of polypropylene.
  • a spinneret was used which had 5479 spinning holes over the width mentioned above.
  • the raw material used was polypropylene granules from Exxon Mobile (Achieve PP3155) with an MFI of 36.
  • the spinning temperature was 272 ° C.
  • the trigger gap had a width of 25 mm.
  • the production speed was set at 46 m / min.
  • the resulting spunbonded fabric had a basis weight of 70 g / m 2 .
  • a 16 g / m 2 layer of very short bicomponent fibers in sheath / core configuration was first applied by means of an airlaid web forming apparatus in which the core was polypropylene and the sheath was polyethylene. The weight ratio of the components was 50/50%. Thereafter, the spunbond was subjected to hydroentanglement. The consolidation was carried out with the help of 6 beams, which alternately acted from both sides.
  • the water pressure used was set as follows: Bar no. 1 2 3 4 5 6 Water pressure (bar) 20 50 50 50 150 150
  • the short fibers were extensively drawn into the spunbonded fabric so that they did not form a pure surface layer.
  • the spunbonded nonwoven thus consolidated had the following mechanical values at a basis weight of 86 g / m 2: Maximum tensile force [N / 5cm] maximum stress Strength at 5% Elongation [N / 5cm] Strength at 10% Elongation [N / 5cm] [%] along 512 85 56 93 crosswise 86 105 6.0 11.9
  • the specific longitudinal strength was 5.95 N / 5 cm per g / m 2 and the specific secant modulus at 5% elongation was 0.65 N / 5 cm per g / m 2.
  • the short binder fibers were largely incorporated into the spunbonded fabric so that they did not form a pure surface layer.
  • the spunbonded nonwoven thus consolidated had the following mechanical properties at a basis weight of 87 g / m 2: ultimate tensile strength maximum stress Force at 5% stretch Force at 10% strain [N / 5cm] [%] [N / 5cm] [N / 5cm] along 530 88 59 96 crosswise 93 100 6.1 12.6
  • the specific longitudinal strength was 6.09 N / 5 cm per g / m 2 and the specific secant modulus at 5% elongation was 0.68 N / 5 cm per g / m 2.
