Definitions

  • the present invention relates to the use of a cellulosic staple fibre of the Lyocell type as well as of textile mixtures containing said fibre.
  • a tertiary amine-oxide in particular N-methylmorpholine-N-oxide (NMMO)
  • NMMO N-methylmorpholine-N-oxide
  • the process for the production of moulded bodies from a solution of cellulose in an aqueous tertiary amine oxide is referred to as the “amine-oxide process” or “Lyocell process”.
  • the solution of cellulose is usually extruded by means of a forming tool, whereby it is moulded. Via an air gap, the moulded solution gets into a precipitation bath, where the moulded body is obtained by precipitating the solution. The moulded body is washed and dried, optionally after further treatment steps.
  • Lyocell fibres produced from such solutions are called “solvent-spun” fibres and have received by BISFA (The International Bureau for the Standardisation of man made Fibres) the generic name Lyocell.
  • BISFA The International Bureau for the Standardisation of man made Fibres
  • a process for the production of Lyocell fibres is described, for instance, in U.S. Pat. No. 4,246,221.
  • the amine-oxide process yields fibres which are distinguished by a high tensile strength, a high wet-modulus and a high loop strength.
  • Lyocell fibres are mainly used in the form of cut fibres of a discrete length, i.e. as so-called “staple fibres”. If in the following “Lyocell fibres” are mentioned, Lyocell fibres in the form of staple fibres are meant by that.
  • Lyocell fibres as filling fibres, for instance, in the form of fleeces in quilts and as pellets in cushions.
  • advantage of Lyocell fibres over other fibre types such as, f.i., polyester fibres lies in their excellent physiological features.
  • the lower bulk resilience and washing resistance, as compared to polyester fibres, must be noted as a disadvantage.
  • textile mixtures of Lyocell and polyester fibres are recommended. Such mixtures are described, for instance, in EP-A 0 941 209.
  • Lyocell fibres for example for coffered blankets.
  • Those mixtures can be produced both in the dry state and in the wet state.
  • a cellulosic staple fibre of the Lyocell type with a value of the ratio between titre (in dtex) and cutting length (in mm) of 0.10 or more is used as a filling fibre for blankets, cushions, pillows, mattresses or fleeces for upholstered furniture.
  • Lyocell fibres with a higher value of the ratio between titre and cutting length display a lower tendency toward entanglements and produce, for instance, very homogeneous mixtures with downs.
  • Lyocell fibres whose value of the ratio between titre and cutting length is 0.5 to 5 have turned out to be an excellent type of fibre, in particular for mixtures with downs.
  • the titre of the fibre used according to the invention preferably is 1.3 to 3.3 dtex, particularly preferably to 1.3 to 1.7 dtex.
  • the fibre used according to the invention has a titre of 6.7 dtex and a cutting length of 6 mm.
  • Cutting length should not fall short of 3 mm.
  • Cutting lengths of 22-30 mm have proven to be suitable if the fibre is used in fibre pellets, for use in fleeces, cutting lengths of up to 60 mm are suitable.
  • the fibre used according to the invention is preferably provided in a siliconized form.
  • the above-defined fibre of the Lyocell type is used in a mixture with at least one fibre of a different fibre type and/or with downs and feathers.
  • the textile mixture can be provided, for instance, in the form of a fleece or pellet.
  • this fibre is preferably selected from the group of synthetic fibres, particularly preferably from the group consisting of polyester fibres, polyamide fibres, polypropylene fibres and polylactate fibres.
  • the content of the above-defined Lyocell fibre in the mixture preferably is 30 to 50% by weight.
  • a further aspect of the present invention consists in a blanket, a cushion, a pillow, a mattress or a fleece for upholstered furniture, containing a staple fibre of the Lyocell type as defined above and/or a mixture as defined above as a filling fibre.
  • Lyocell fibres with a particular ratio between titre and cutting length and textile mixtures, respectively, containing said fibre are perfectly suitable for use as a filling fibre.
