Definitions

  • the invention relates to highly functional spunbonded nonwovens as textile fabrics which can be produced directly from dissolved polymers by means of known spunbonding processes and which are constructed from fibers filled with liquid and / or solid functional additives.
  • the fibers consist of more than 40 wt.%, Based on the total weight of the fibers, from functional additive, their average fiber diameter is 0.1 to 500 microns and the diameter variations within a fiber or each other is at least 30%.
  • the spunbonded fabric is characterized by a high degree of functionality as a result of very high concentrations of the functional additives and can be used in a variety of ways, for example as a lining material, for hygiene applications, for wound dressings, as support materials, as construction and transport material, as a cosmetic material or as a filter.
  • Filled textile fabrics e.g. those with thermo-regulating, antimicrobial or absorbing properties are already known.
  • the materials hitherto used in the prior art are structures which have been processed into a textile surface after the production of functional fibers by at least one additional process step and / or contain only small amounts of functional particles.
  • the additive components are limited to zinc white (ZnO and ZnS), whereby their proportion is limited to a maximum of 30% and particle sizes are smaller than 15 ⁇ m. It is mentioned that for Fleece applications, the particle content may also be higher, but there is no teaching taught how such nonwovens are produced.
  • the aim was not a functional nonwoven with high particle content, but washable and dyeable bactericidal bodies / fibers with controlled release of the active ingredients with prescribed washing permanence.
  • the melts can be processed into a spunbonded, for example in the EP 1 199 393 A2 , This is a spunbond made of thermoplastic polymers with hydrophobic additives.
  • the aim is an enrichment of the hydrophobic additives on the fiber surface. This is achieved by the fact that the fiber is warped by the air flow so far that the mean fiber diameter is equal to the particle diameter or is reduced to at most half of the particle diameter.
  • the proportion of masterbatches with the additives is between 10 and 20 wt .-% and may not be higher, so as not to affect the further processing to roofing membranes or use in sanitary napkins.
  • Particle-containing filaments or fibers can not be stably spun in a very high proportion of functional particles from 40% in normal filament or fiber spinning processes, since frequent breaks would result.
  • fiber materials with functional added value for the end user, which should also be inexpensive to produce and easy to process.
  • Areas of application of such fiber materials are, for example, in the clothing industry as an insert material, in technical textiles, for example hygiene applications, for wound dressings, as support materials, as construction and transport material, as a cosmetic material or as a filter, for example for the filtration of wastewater or exhaust air and binding of air and water ingredients.
  • Fabrics with functional additives can be prepared in principle either by the surface formation along a textile value chain or web formation from each provided with functional additives fibers, the coating of flat textile structures with additive dispersions or the incorporation of solid or liquid functional additives in already produced nonwoven structures.
  • Fibers with a content of functional additives of more than 40% by weight can not be stably spun in normal fiber spinning processes, since frequent fiber breaks are the result. Although this disadvantage can be partially compensated by the use of functional fibers which are produced by solution spinning processes, the downstream textile surface forming processes also require at least one additional processing step in each case.
  • the materials hitherto produced in the prior art are structures that have been processed into a textile surface by at least one additional process step after separate production of functional fibers and / or only small amounts of functional particles include. Due to the separate nonwoven production process, the highly filled fibers are additionally stressed and thereby damaged and only meet lower quality requirements in terms of functionality or mechanical resistance.
  • the aim of the present invention is to provide a versatile sheet of particulate filaments and fibers having high functional utility for various applications, Depending on the nature of the functional particles to make available, wherein the particulate filaments or fibers consist of more than 40 wt .-% of functional additives and have an average diameter of 0.1 to 500 microns.
  • the fabrics are said to have already reached such a level of stability immediately after being deposited that they are suitable for further processing or for direct use. Due to the high content of functional additives, these fabrics should have such functional properties as are otherwise achieved only by additional process steps such as coating or surface finishing.
  • the subject of the present invention is accordingly a highly functional spunbonded non-meltable polymer-based fiber containing one or more functional additives characterized in that the fibers are intertwined and entangled, have a different length with aspect ratios above 1,000 and a solid one Form nonwoven composite, wherein the fibers have a middle Diameters of 0.1 to 500 micrometers and diameter variations within a fiber and / or with each other of at least 30% and wherein the fibers in addition to the non-meltable polymer more than 40 wt .-%, based on the total weight of the fibers, of functional additives in solid and / or liquid form, which are finely distributed in the fibers

  • the production of the additive-containing fabrics from particle-containing filaments or fibers is effected by a spunbonding process.
  • a doped polymer-containing spinning solution is used in the fiber-forming process, wherein the direct solvent is preferably an aprotic solvent.
  • Particularly suitable as direct solvents, especially for cellulose are N-methyl-morpholine-N-oxide or N-methyl-morpholine-N-oxide-monohydrate, ionic liquids, such as 1-ethyl-3-methylimidazolium-acetate, 3- Ethyl 1-methylimidazolium chloride or 3-butyl-1-methylimidazolium chloride, dimethylformamide, dimethylacetamide or dimethyl sulfoxide mixed with lithium chloride or NaOH-thiourea-water or possibly also mixtures thereof.

  • the resulting fiber cracks do not lead to a termination of the process and do not adversely affect the process of web formation. They lead to fibers of different lengths and varying diameters being present in a nonwoven.
  • the fibers are subsequently stabilized in their shape (during the transition into the stress-free space) before the onset of longitudinal relaxation.
  • the fibers or filaments are deposited on a wire belt or a screen drum to form a nonwoven, which may also be layered, and compressed by suction.
  • the solvent-enriched excess water is separated off, the remaining solvent rinsed by washing several times and then optionally the resulting nonwoven can be dried, wherein the functional particles in the non-woven filaments and / or fibers by the taking place swelling of the polymer property determining mutually reinforced touch and connect.

  • a non-melting polymer ie a polymer in which the softening point is above the decomposition point.
  • It is preferably a member of the group of natural polymers, for example the polysaccharides, particularly preferably cellulose, the polysaccharide derivatives or the proteins or protein derivatives and / or from the group of solution-formable synthetic polymers, for example polyacrylonitrile, polyvinyl alcohol, Polyethylene oxide, polysulfone, meta-aramid or their copolymers.
  • the wet spunbonded fabric obtained in this way can be consolidated, finished and shaped by textile processes (needle punching, hydroentanglement, chemical bonding), the solidification and refinement of the nonwoven fabric being able to take place before or after drying. Aftertreatment by, for example, lubricants, impregnations or with ionic active substances may follow.
  • a spunbond web is understood to mean a web of fibers and continuous fibers laid down directly in random orientation after the extrusion, in which case it is also possible to lay several layers one above the other.
  • the mixture of fibers and continuous fibers is caused by fiber breaks after the nozzle, resulting from the high particle content, but do not lead to an interruption of the process.
  • the spunbonded nonwoven not only consists of fibers of different lengths, but the fibers themselves have different fiber thicknesses over their length or with each other. The fiber thickness is determined by various factors, such as the concentration of the solution, the rate of blowing, the type of polymer, the particle size, as well as interaction of the additives to other components of the solution and content of additives.
  • Characteristic features are the irregularities in the mean diameter of the fibers due to the high particle content, the size of the particles and the fiber breaks, which are visually very easily discernible under a microscope.
  • the highly functional spunbonded nonwoven has a basis weight of 2 to 1000 g / m 2 , preferably of 5 to 500 g / m 2 and a thickness of 0.01 to 20 mm, preferably from 0.05 to 5 mm.

  • a highly functional spunbond web of particulate filaments or fibers ranges from apparel materials, such as heat-trapping or active ingredient release liners, to technical textiles with high functional utility for various applications - depending on the type of functional particles, for example for hygiene applications, as wound dressings, as carrier materials for active ingredients or as support materials in composites, as Construction and transport material, as a cosmetic material or as a filter, for example for the filtration and binding of air and water ingredients such as phosphates, nitrates and ammonium-nitrogen compounds. Due to the special characteristics of the functional properties, due to the high concentration of additives, these nonwovens are also suitable for layered composites with other fabrics. This can happen by producing the highly functional spunbonded fabric on another, already introduced fabric during spunbonding production.
  • Some of the resulting fiber cable pieces were completely freed of solvent and cut, as far as possible, to a staple length of 40 mm, with the described bonds sorted out as far as possible.
  • the fibers were treated with a 1% sodium chloride solution and dried at 55 ° C to constant weight. A secondary spinning to the yarn was not possible. A fleece formation was only partially possible, while a large number of short fibers and extreme shortening of the fibers was observed. The irregular loose fleece sections could not be further processed or used. A consolidation by needling for stabilization was not possible because the fleece was completely destroyed and fell apart.
  • a cellulose solution prepared according to Example 1 was solidified by melt-blown spinning (solution blowing) at a solution temperature of 95 ° C, blowing with 80 ° C warm air, and spraying with a water mist directly at the exit of the nozzle blower unit and depositing on a screen belt deformed into a direct web.
