Definitions

  • the invention relates to the use of a nonwoven fabric of continuous filaments for preventing the leakage of down from a down filled textile product, wherein the continuous filaments have a titer less than 0.15 dtex.
  • the invention also relates to down-filled textile products and methods for their preparation.
  • Down also known as lower springs, are feathers with short keel and soft feathered branches. Down is used in textile products, such as bedding, jackets or sleeping bags, as thermal insulation fillers. The downs are contained and enclosed in sheaths of flat textile structures. Down-filled textile products must be "down-proof" when used as intended. This means that the down does not penetrate or even get out of the sheaths. Since quills of down are pointed and hard, the shells must have a high strength. In particular, dense and strong tissues are suitable as casings. Fabrics consist of interwoven weft threads and warp threads. Down quills, which are pointed, but generally much larger than fabric threads and fabric stitches, can not penetrate fabrics because the fibers are not sufficiently slidable. The down density of fabrics can be tested in a standardized method according to DIN 12132-1.
  • textile nonwovens are not suitable as sheaths for filling with down. Even thick textile nonwovens are relatively easily penetrated by down. Because the fibers of conventional nonwoven fabrics are disordered and therefore mutually displaceable, down quills can easily penetrate them. The down density of nonwovens can be achieved if they are solidified thermally or chemically. The fibers are then bonded to each other in a similar way as in a tissue and no longer freely displaceable against each other. However, such surface solidification is unacceptable in textile applications, as it leads to unfavorable properties, such as low softness and elasticity, low porosity and associated low air and moisture permeability. Therefore, the prior art generally uses fabric for down fillings.
  • nonwoven fabrics in particular have many advantageous properties which distinguish them from fabrics, such as high softness, elasticity, stability, porosity, high air and moisture permeability, but also good availability and processability ,
  • nonwovens for the storage of down as a component of laminates.
  • the JP2008 / 303480A to use a composite material of a fabric with a nonwoven fabric.
  • the JP2006 / 291421A discloses down-density laminates containing thermally bonded nonwovens.
  • Laminates are also relatively expensive to produce, also because the components must be glued or otherwise firmly connected.
  • the German utility model DE 203 10 279 U1 describes bedding envelopes made of microfiber webs with good air permeability, which provides protection against allergens and mites.
  • the sheaths have characteristic mechanical properties characteristic of nonwoven fabrics, for example in terms of washability and stability.
  • the disclosure also claims that the microfiber web is downproof. For this, however, no proof is provided.
  • the microfiber web according to the embodiment of the DE 203 10 279 U1 is a true nonwoven fabric that has not been thermally consolidated, nor reinforced by other layers in a laminate. Therefore, the fibers in non-solidified areas are mutually displaceable and it is not believable by those skilled in the art that such a conventional nonwoven fabric is down-proof.
  • the Applicant of the present application has therefore examined whether the claim of DE 203 10 279 U1 It is true that such fine microfiber nonwovens are downproof.
  • the DE 203 10 279 U1 has an "embodiment", in which, however, no information on the origin or the production of the nonwoven fabric are made.
  • the general information on the nature of the microfiber nonwoven fabric are relatively superficial.
  • the microfiber nonwoven fabric described therein essentially corresponds to a commercially available product of the brand Evolon 100 from Freudenberg, DE, which was commercially available in 2003.
  • the Evolon brand product is made from 16 microfiber composite filaments per filament in cupcake form (PIE16).
  • the individual fibers are produced from cake-shaped segments, they have an edgy cross-sectional profile, which approximately resembles a triangle.
  • the nonwovens are solidified by water jet treatment, wherein the composite filaments are split into individual filaments of polyethylene terephthalate (PET) and polyamide (PA).
  • PET polyethylene terephthalate
  • PA polyamide
  • the fiber thickness of the composite filament is about 2.4 dtex and that of the individual fibers after splitting about 0.2 dtex and 0.1 dtex.
  • the nonwoven fabric Evolon 100 with respect to the polyamide fiber component would be even finer than that in the DE 203 10 279 U1 described. But it is to be assumed that in the embodiment of DE 203 10 279 U1 a microfiber nonwoven fabric Evolon 100 Freudenberg was described and investigated.
  • test specification actually serves for the investigation of fabrics, but can be used analogously and without substantive modification for nonwovens.
  • a corresponding standard for nonwovens is only not available because in the prior art there was no need for it, since nonwovens are in principle not downproof. Thus, it was possible to confirm the general knowledge that such nonwovens are resistant to allergens, mosquito bites or mites, but not to down.
  • the Applicant has also microscopically studied the effect of down feathers on such a microfiber nonwoven fabric.
  • the result is in the Fig. 1 to 4 shown.
  • the Fig. 1 and 2 show a typical down feather after penetration of the microfiber nonwoven fabric at different magnifications.
  • the down quill has a point, with which it can penetrate into the much finer fleece material.
  • the quill has fine barbs that support directional penetration.
  • Fig. 3 shows a down feather in the process of penetration of the nonwoven fabric.
  • Fig. 4 shows a typical hole that has drilled a down through the nonwoven fabric.
  • the lack of down density of the microfiber nonwoven according to DE 203 10 279 U1 is in line with the general knowledge that non-thermally bonded nonwovens, even if made of very fine fibers, are not down-resistant.
  • the DE 203 10 279 U1 contains no teaching to overcome the known disadvantages of nonwovens regarding the lack of down density. Nonwovens known in the prior art were therefore only suitable for the storage of down, if they sufficiently thermally consolidated or combined in laminates with other layers.
  • the invention has for its object to provide materials for the storage of down for textile applications, which solve the problems described above.
  • This textile products are to be provided with good mechanical properties to keep down.
  • the textile products should in particular have a high softness and elasticity, porosity, air and moisture permeability, but at the same time be down-proof.
  • the materials should be relatively easily available and the manufacturing process should as far as possible involve no complex processing steps, such as lamination or special post-treatment steps. Overall, the material should be both easily provided by the manufacturer, as well as highly acceptable to the user.
  • the invention relates to the use of a continuous filament nonwoven fabric to prevent feather leakage from a down filled textile product, which nonwoven fabric is obtainable by a spun process wherein composite filaments are laid down to a nonwoven, after which the composite filaments are deposited in continuous filaments having a denier of less than 0.15 dtex are split and the nonwoven is mechanically bonded to a nonwoven fabric, wherein the nonwoven fabric is not thermally or chemically solidified surface.
  • the use according to the invention is carried out with a down filled textile product.
  • the textile product has a sheath enclosing a cavity in which the downs are contained and sealed from the environment.
  • the nonwoven fabric forms the shell of the textile product or a part thereof.
  • Nonwovens are according to the definition of DIN 61 210 (Part 2, 1988) textile fabrics made of loosely deposited fibers by Friction, cohesion or adhesion are interconnected.
  • the nonwoven fabric as a shell and barrier keeps the down from escaping from the textile product.
  • the nonwoven fabric consists of continuous filaments.
  • filaments refers to fibers which, in contrast to staple fibers, are produced in a continuous process and are deposited directly into a nonwoven.
  • down refers to down feathers (bottom feathers) of birds which are suitable for textile fillings.
  • a definition of down is given in DIN 12934. Down are especially feathers with a very short keel and long, radially arranged spring branches. Down also regularly has fewer hooks than other feathers. Because of their high elasticity and dimensional stability in combination with heat-insulating properties down are used for a variety of textile applications.
  • the use of the invention is to prevent the escape of down from a down filled textile product.
  • the down filling is contained in a wrapper which separates it from the environment.
  • exit refers to any movement of the down, in which the shell is penetrated.
  • the down can penetrate the shell only partially or completely.
  • the term “leakage” includes feathers of down only drilling part of the tip through the shell and getting stuck in it, or they can completely penetrate the shell and leave the textile product.
  • the down density is preferably determined according to the simulated cushion stress test of DIN EN 12132-1, part 1, wherein the nonwoven fabric is used instead of a fabric.
  • the nonwoven fabric passes the test according to DIN EN 12132-1, which means that in each direction tested (longitudinal and transverse) not more than 20 particles emerge, ie stuck in the textile material or have penetrated this.
  • An average value is preferably evaluated from a plurality of individual measurements, for example, 5, 10 or 20 individual measurements. In particular, no more than 15 particles, in particular no more than 12 particles, are emitted in the test.
  • the nonwoven directly contacts the down filling. This means that there is no additional layer between the nonwoven fabric and the down. The downs touch the nonwoven fabric and would penetrate it if the down density were insufficient.
  • the nonwoven fabric is preferably used as a textile shell in which the downs are contained. This means that the nonwoven fabric per se forms the shell. He is not part of a laminate with other, other layers. Thus, if the textile product is, for example, a bedding product, the nonwoven fabric would include the down.
  • a nonwoven fabric per se of fibers with a titre ⁇ 0.15 dtex without the need for thermal consolidation or lamination with further layers, in particular fabric layers or stronger nonwoven fabric layers, can prevent the leakage of down.
  • Composite filaments are filaments of at least two different parallel filaments, which have phase boundary and are splittably interconnected.
  • the composite filaments are split into continuous filaments with a titre of less than 0.15 dtex.
  • the filaments have a titer ⁇ 0.15 dtex.
  • the nonwoven fabric has as filament component substantially or exclusively filaments with a corresponding titer.
  • Such nonwovens may have smaller local areas in which composite filaments were not or only partially cleaved. With a sufficient mechanical cleavage, in particular by means of water jet treatment, but nonwovens can be obtained, which consist almost exclusively of single filaments.
  • At least 80%, in particular at least 90%, at least 95%, at least 98% or about 100% of individual filaments are present, based on the total volume of the fibers.
  • the proportion can be determined microscopically by examining randomly selected sections of a nonwoven fabric.
  • the cleavage takes place in continuous filaments with a titre of less than 0.14 dtex, more preferably less than 0.12 dtex or less than 0.11 dtex.
