Definitions

  • the present invention relates to a method for producing a cellulosic fiber, in particular a lyocell fiber, which is particularly well suited for mixing with feathers, in particular with down, due to its improved opening behavior, such a filler fiber and the use of this filling fiber in blends, as well as bedding and Clothing filled with these blends.
  • melt-extruded synthetic polymers such as polyester, polylactic acid and others are known and widely used.
  • Cellulosic fibers in particular the solvent-spun fibers designated by the generic name Lyocell from BISFA (The International Bureau for the Standardization of Man Made Fibers) have been known for a long time and have been produced on an industrial scale for years.
  • the solvent used is a tertiary amine oxide, in particular N-methylmorpholine-N-oxide (NMMO).
  • NMMO N-methylmorpholine-N-oxide
  • ionic liquids are also suitable as solvents.
  • the solution of cellulose is usually extruded in this process by means of a molding tool and thereby formed.
  • the shaped solution passes, for example, in a so-called dry-wet spinning process via a Lucasspaft in a precipitation bath, which is obtained by precipitation of the solution, the shaped body.
  • the molding is washed, and if necessary, dried after further treatment steps.
  • a method for producing Lyocellmaschinen is z. B. in the US 4,246,221 described,
  • WO 94/28220 relates to a process for crimping cellulosic filaments prepared by a dry-wet spinning process by means of a buffing chamber crimping to obtain an adhesion similar to naturally crimped natural fibers.
  • WO95 / 24520 discloses a crimping process of lyocell fibers in the wet state by means of a stuffer box to obtain a permanent crimp. These fibers are particularly suitable for use in filters.
  • lyocell fibers with a denier of 6.7 dtex and a cut length of 11 mm are proposed as mixing partners for feathers and down.
  • the mixture of lyocell and feathers or down is done in a wet mixing process.
  • the opening behavior of Lyocell fibers and related problems contains the WO 2004/070093 A2 no hints.
  • lyocell fibers in the titer range of from 0.7 to 8.0 dtex and a cut length of from 5 to 100 mm are described in detail for use as filler for disposable quilts consisting of pure lyocell or blends with other, preferably biodegradable synthetic fibers. Lyocell as a blending partner for feathers and down is only suggested incidentally, without pointing to the associated processing problems or even revealing a solution to such problems.
  • lyocell staple fibers with a value of the ratio of denier (in dtex) to cut length (in mm) of 0.10 or more known as fill fiber for blankets, upholstery, pillows, Gurtratzen or fleece for upholstered furniture.
  • the use of such fibers for mixing with fibers of other Fasergattungen or with down and feathers is described there.
  • processors of down and feathers do not generally have the usual additional opening equipment otherwise used in textile manufacturing.
  • the synthetic fibers such as polyester, which are widely used as compound fibers, are easy to open, so that no aggressive opening units have to be used for processing such fibers.
  • the majority of the down and feathers is processed in the dry state, with aggregates fans and blowpipes for Opening, mixing and transporting are used.
  • the lyocell fibers known from the above-mentioned process are used as the mixing partner, then the fibers are poorly opened due to the strong compression in the bale. In this case, larger structures of unintentionally solidified fibers can get into the subsequent processing machines and destroy their sensitive parts. A homogeneous mixture with down and feathers is not possible with these fibers.
  • the WO 2005/007945 does not address the problem of inadequate opening possibilities of a commercially pressed fiber bale with the equipment available at down processors.
  • the object of the present invention therefore was to provide a fiber that can be opened without the application of the usual in the textile industry opening units and then processed into a homogeneous mixture with down and feathers.
  • a further object was to provide a method by means of which a fiber can be produced which can be opened without the use of the opening units customary in the textile industry and subsequently processed to a homogeneous mixture with down and feathers.
  • These fibers have an excellent opening behavior with simple aggregates even after strong compression in a commercially available fiber bale, which can be determined in the practical, so-called blowbox test.
  • Fibers having a single fiber titer that is significantly less than 0.7 dtex are too fine for their intended use as filler fiber, for example because they do not have sufficient bulkability. Fibers with a single fiber titer significantly greater than 6.0 dtex are too thick and stiff and therefore do not provide a soft filling as required by a product with down and / or feather from the consumer.
  • the stuffer box crimping took place after the in WO95 / 24520 described method. Surprisingly, it has been found that these fibers have better opening properties than lyocell fibers which were produced by means of the abovementioned nonwoven aftertreatment. In particular, it was surprising that a fiber crimped in a stuffer box could be opened much better than a fiber crimped in a fleece aftertreatment.
  • a fiber crimped in a stuffer box differs significantly from a fiber crimped in a fleece aftertreatment.
  • a fiber crimped in a fleece aftertreatment for example, in one according to the EP 797 696
  • nonwoven crimped fiber permanent crushing sites exist, which are clearly visible in the polarizing microscope. While such nonwoven crimping is advantageous for various textile and other applications, it has the disadvantage of poorer opening performance for the field of the present invention.
  • the filling fiber according to the invention preferably has a number of sheets of 18 to 50 sheets / 10 cm, more preferably an arc number of 18 to 40 sheets / 10 cm.
  • a lower number of sheets results in too low bulkiness of the filling fiber, while higher than the mentioned numbers of sheets in turn worsen the opening behavior, since more entanglements can occur between the individual fibers.
  • finishing layer of from 0.3 to 3.0% by weight, based on the total weight of the finished fiber. While lower finishing requirements lead to a poorer sliding behavior and thus to a poorer opening behavior, higher finishing requirements are on the one hand more expensive due to the higher consumption of chemicals, leave too wet or greasy feel of the fibers and also worsen the opening and further processing behavior.
  • an amino-functionalized lubricant is particularly preferred.
  • the amino groups in the lubricant significantly contribute to the adjustment of the lubricating behavior which is important for the filling fiber according to the invention, which makes possible the good opening behavior and the necessary bulk.
  • the type of Furitechnischalmaschine has greater influence on the gliding behavior than the basic substance of the Avivage.
  • the base substance of the finish are all chemical compounds known for this purpose, for example silicone oils or avivages based on fatty acids.
  • a silicone oil is preferred for the present invention, since this is the best permanence. Permanence should be understood here as the ability to remain on the fiber as long as possible, for example even after several washes.
  • the filler fibers according to the invention therefore preferably have a blowbox height ratio between 4 and 15, particularly preferably between 6 and 14.
  • the lubricant used in the process according to the invention is preferably a silicone oil.
  • Decisive for the opening and further processing properties of the filling fiber is also its finishing layer. It should be between 0.3 and 3.0% by weight, based on the total weight of the refined fiber.
  • the fibers are preferably spun in a dry-wet spinning process, for example one of the known lyocell processes with aqueous amine oxides or ionic liquids as solvent for the cellulose.
  • the object is also achieved by the use of a cellulosic filler fiber with a Einzelmaschinetiter from 0.7 to 6.0 dtex, preferably 0.8 to 3.0 dtex, which generates a crimping in a stuffer box with a sheet count of at least 18 sheets / 10cm as well as a finishing layer, as filling material in bedding and clothing.
  • the cellulosic filling fiber used for this purpose preferably has a blowbox height ratio between 4 and 15, preferably between 6 and 14.
  • the blowbox height ratio is the quotient of the blowbox height and the initial height.
  • Lyocell fibers with a single fiber titer of 1.7 dtex were formed by the known process by extrusion of a solution of cellulose in aqueous amine oxide, coagulated by a dry-wet spinning process and cut, washed, dried and coated in a prior art nonwoven aftertreatment a silicone oil so that they had a Avivageauflage between 0.8 and 1.2 wt.% Had.
  • a single value can not be specified for this parameter, because even with careful application of the finish, the circulation in the nonwoven fabric varies within certain limits.
  • the fibers were baled on a commercial scale Autefa baler on a production scale. Samples were then taken according to the method described above.
  • Lyocell fibers with a single fiber titer of 1.7 dtex were formed by extrusion of a solution of cellulose in aqueous amine oxide, coagulated in a dry-wet spinning process and washed in a cable post-treatment, dried, crimped in a stuffer box crimp and with an amino-functionalized silicone oil Type Wacker finish CT96E, so that they had a lubricant deposit between 0.7 and 0.9% by weight. Only then was the cable cut. The fibers were baled on a commercial scale Autefa baler on a production scale. Samples were then taken according to the method described above.
  • the fibers produced according to the method of the invention show a much better opening behavior than those of the prior art.
