Definitions

  • the present invention relates to a method for producing a cellulosic fiber, in particular a lyocell fiber, which is particularly suitable for mixing with feathers, in particular down, due to its improved opening behavior, such a full fiber and the use of this full-fiber in blends, as well as bedding and Clothing filled with these blends
  • Short fibers from melt-extruded, synthetic polymers such as polyester, polylactic acid and others are known and widely used as full fibers in combination with down and feathers
  • lyocell fibers in particular those produced by BISFA (The International Bureau for the Standardization of Man Made Fibers) with the generic name Lyocell, have long been known and have been produced on a large scale for years.
  • the solvent used is a tertiary amine oxide , in particular N-Methylmorphol ⁇ n-N-Ox ⁇ d (NMMO) also used as solvents are ionic liquids
  • the solution of the cellulose is usually extruded in this process by means of a mold and thereby formed
  • the shaped solution passes, for example, in a so-called dry-wet spinning process via an air gap in a falling bath, which is obtained by precipitation of the solution, the moldings
  • the molded article is washed and optionally dried for further treatment steps.
  • a process for producing lyocell fibers is described, for example, in US Pat. No. 4,246,221
  • lyocell fibers as full fibers in the form of nonwovens in quilts and as cushions in pillows.
  • crimped lyocell staple fibers for nonwovens and balls are described as suitable full-fiber types.
  • this publication does not give any information on the fiber titer on the cut length of the fibers or on surface treatments WO 99/16705 does not address the opening behavior of the fibers and the resulting problems
  • WO 2004/070093 A2 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 the lyocell fibers and associated problems, WO 2004/070093 A2 contains no evidence.
  • lyocell fibers in the titer range of 0.7 to 8.0 dtex and a cut length of 5 to 100 mm are used in WO 2004/023943 for use as filling material for disposable quilts made from pure lyocell or else from mixtures with other, preferably biodegradable Synthetic fibers exist, described in detail. 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.
  • WO 2005/007945 discloses the use of lyocell staple fibers with a value of the ratio of denier (in dtex) to cut length (in mm) of 0.10 or more as filler fiber for blankets, upholstery, cushions, mattresses or fleece for upholstered furniture known. 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 fibers are used to process such fibers
  • Opening units must be used.
  • the majority of the down and feathers is processed in the dry state, with aggregates fans and blowpipes for Opening, mixing and transport are used If now the lyocell fibers known from the above-mentioned method are used as the mixing partner, then there is insufficient opening of the fibers due to the strong pressing in the bale. Larger structures of unintentionally consolidated fibers can pass into the subsequent processing machines and their sensitive parts destroy Homogeneous mixing with down and feathers is not possible with these fibers WO 2005/007945 is also not concerned with the problem of poor opening possibilities of a commercially pressed fiber bale with devices present in down processors
  • the object of the present invention Compared to the known prior art, the object of the present invention, then, to provide a fiber available, which can be opened without the use of customary in the textile industry O Stammsaggregate and then processed to a homogeneous mixture with down and feathers
  • Another object was then to provide a method by which a fiber can be produced which can be opened without the use of the usual in the textile industry O Stammsaggregate and then processed to a homogeneous mixture with down and feathers
  • Fibers with a single fiber titer which is clearly less than 0 7 dtex are too fine for the intended use as a full fiber because they, for example, have no sufficient bulk. Fibers with a single fiber titer of substantially more than 6.0 dtex are too thick and stiff and therefore do not give a soft Filling more as required by a product with down and / or feathers from the consumer
  • the stuffer box crimping was carried out according to the method described in WO 95/24520. 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.
  • permanent crimping points are present in a fiber crimped in the nonwoven according to EP 797 696, 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 in the field of the present invention
  • the full-fiber according to the invention preferably has a number of sheets of 18 to 50 sheets / 10 cm, more preferably a number of sheets of 18 to 40 sheets / 10 cm.
  • a lower number of sheets results in too low bulkiness of the full fiber, while higher than the mentioned numbers of sheets in turn worsen the opening behavior, since more entanglements can occur between the individual fibers
  • It also preferably has a finishing layer of from 0.3 to 3.0% by weight, based on the total mass of the refined fiber.
  • a finishing layer of from 0.3 to 3.0% by weight, based on the total mass of the refined fiber.
  • aminofunctionalized lubricant is particularly preferred as the finishing agent for this fiber.
  • the amino groups in the lubricant contribute substantially to the adjustment of the slip behavior which is important for the filling fiber according to the invention, which makes the good opening behavior and the necessary bulk possible.
  • the type of functionalization has greater influence on the sliding behavior than the Basic substance of the avivage
  • silicone oils or lubricants based on fatty acids is preferred for the present invention, however, a silicone oil, since this is the permanence is to be understood here as the ability to remain on the fiber as long as possible, for example even after several washings
  • inventive full fibers with a staple fiber length between 6 and 20 mm have the best properties too large staple fiber lengths lead to more entanglements and thus to a deterioration of the opening behavior
  • the fiber cable crimped in the stuffer box is cut in the stretched state, ie under tension by commercially available cutting machines in which the cutting length is previously fixed
  • the full fibers according to the invention preferably have a blowbox ratio of between 4 and 15, more preferably between 6 and 14
  • the further object is achieved by a process for producing a cellulosic full-fiber with a single fiber titer of 0.7 to 6.0 dtex, preferably 0.8 to 3.0 dtex consisting of the steps
  • the cable is crimped in a stuffer box to a sheet count of at least 18 sheets / 10cm and then cut and the cut filler fiber has a blowbox height ratio of between 4 and 15, 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 has a blowbox height ratio between 4 and 15, preferably between 6 and 14.
  • the number of sheets is determined by the method described in WO 95/24520.
  • blowbox test The opening properties that are practically relevant for use as a filler fiber in combination with down and feathers can be tested on a laboratory scale using the method described in the following, the so-called blowbox test:
  • the blowbox is a rectangular metal container which is open at the bottom and at the top with one air-permeable sieve is covered.
  • the dimensions of the blowbox are 20 x 15 x 20 cm (length x width x height, ie 6 l volume).
  • the determination of the opening properties is carried out as follows, the average value of two tests always being used to determine reliable results
  • blowbox high ratio is the quotient of blowbox height and output height
  • Figure 4 shows, for example, fibers with the grade 9 for the opening good Examples:
  • Lyocell fibers with a single fiber titer of 1.7 dtex were formed by the known method by extrusion of a solution of cellulose in aqueous amine oxide, coagulated in a dry-wet spinning process, and cut, washed, dried, and in a nonwoven aftertreatment according to the prior art with 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 a known method by extrusion of a solution of cellulose in aqueous amine oxide, coagulated in a dry-wet-spun and washed in a KabeJ ⁇ acbbehandJung, 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.
