Definitions

  • the present invention relates to a chenille yarn that contains mainly acrylic (in particular more than 50% acrylic) in the pile, and the use of such a yarn in a fabric, in particular in an upholstery fabric or furnishing fabric.
  • Chenille yarn is composed of a chenille core and a chenille pile.
  • the chenille core is composed of at least 2 threads that are twisted (twined) around each other, and between which the pile fibres are retained.
  • the pile fibres, which form the chenille pile may be composed of either cut or uncut pile. It is particularly preferable for the chenille core to be fully or partially in the form of a spun yarn (staple yarn) because this improves the strength of the pile.
  • chenille yarns that in particular contain more than 50% of acrylic in the pile it is customary in the art to use a core of the raw material most used in the pile. The reason for this lies in the dyeing of the yarn or the fabric containing these yarns.
  • Various methods of dyeing chenille yarns or fabrics are known in the art.
  • a first method starts off with plain ecru chenille yarn, the core and the pile of which in particular are made of 100% acrylic. Everything can then be dyed in one dyeing operation, and using the same dyes.
  • a second method is to start from a chenille core that is only partly made of ecru acrylic.
  • the pile consists, for example, of two different raw materials, namely acrylic and viscose.
  • the core of this yarn is then composed of the same raw material as the material most used in the pile. In the dyeing process only acrylic is then dyed. In another process a chenille yarn composed of coloured pile yarns is used. This chenille is no longer dyed, which has the advantage that it has a good appearance and is not flattened by the effect of the dyeing process.
  • the chenille pile can also consist of two (or more) raw materials. These raw materials can be in several different colours. In the art an effort is always made to have a chenille core that is not visible through the chenille pile, because a visible core would give a poor appearance. For that reason, an effort is always made to ensure that the core is the same colour as the pile, and that the pile covers the core sufficiently.
  • British patent GB 988072 relates to a fire-resistant fabric made of chenille yarns in which the pile consists substantially of polyvinyl chloride (PVC) and/or polyvinylidene chloride, and which have a core consisting of normal textile fibre such as, for example, cotton, wool, rayon or synthetic fibres.
  • PVC polyvinyl chloride
  • the special application of such a yarn in an upholstery fabric is not known from this patent, not to mention the standards that have to be met for such an application.
  • a disadvantage of a chenille yarn in which the pile consists substantially of PVC is that the material has an unpleasant feel and imposes limitations in available colours. It is also known that such materials have great heat sensitivity and that during heat treatments such as ironing, washing or dyeing great shrinkage occurs.
  • PVC is dyed with disperse dyes, which cannot be used for acrylic.
  • US patent 6.107.218 relates to chenille yarns which can be used on high speed machines such as air-jet or water-jet looms.
  • the chenille core is therefor composed of at least one low melting binder core yarn and at least one other core yarn.
  • the chenille yarn is subjected to a heath treatment so that the low melting component melts and fixes the chenille pile in the yarn, and to a subsequent cooling step before winding the yarn on bobbins.
  • the obtained yarns show improved weaving performance, but involve the drawback of increased combustibility of the fabric, due to the presence of the low melting binder core yarn.”
  • One object of the present invention is to provide a yarn, in particular a chenille yarn, in which the pile is composed mainly of acrylic, and by means of which it is possible to produce fabrics that have fire-retardant properties irrespective of the design, and for which a fire-retardant backcoating with only a small quantity of fire-resistant product is required, so that the pleasant feel is retained.
  • Another object of the present invention is to provide a chenille yarn that is to be used in particular in an upholstery fabric or furnishing fabric, which fabric can be treated with a minimal quantity of fire-resistant agent, which means an advantage for the environment and further gives a supple, non-sticky feel.
  • the present invention provides a chenille yarn in which over 50% in weight of the chenille pile is composed of acrylic (standard acrylic or fire-resistant modified acrylic), characterized in that over 25% of the core of the yarn is composed of other raw materials that can be dyed with the same dyes and/or with the same dye bath as standard acrylic.
  • the core of the yarn consists fully or partially of an anionic modified polyester, while the pile is constituted fully or partially of standard acrylic, and the whole combination can be dyed in one dyeing operation.
  • Anionic modified polyester is known for its great susceptibility to hydrolysis on exposure to a higher temperature or pH. This is caused by the presence of, for example, the sulphonic acid groups.
  • the core of the yarn consists fully or partially of a fire-retardant acrylic.
  • Test 1 of Example 1 was carried out with a chenille yarn having in the pile a standard acrylic, and the core of which yarn consists of anionic modified polyester.
  • the advantage of this construction is that the yarn can be dyed in one dye bath and with the same dyes. This gives the advantage that no additional dye treatment has to be carried out in order to dye the core, which means a saving in energy.
  • Test 2 of Example 1 was carried out with a chenille yarn composed of a pile made of standard acrylic and a core in fire-retardant acrylic.
  • core and pile can be dyed in one and the same dye bath and with the same dyes.
  • Test 3 of Example 1 a chenille yarn consisting of a standard acrylic pile and with the chenille core consisting of fire-retardant acrylic and standard acrylic was used. Fabrics were made with these different yarns and a fire-resistant latex was applied. The fire tests were subsequently carried out in accordance with BS 5852, part 1, and the materials were always found satisfactory.
  • a fabric was made with chenille yarn consisting of a standard acrylic pile and a core consisting of cationic modified polyester yarn.
  • This fabric (fabric 1) was treated with a fire-retardant latex with a weight of 80 g/m2.
  • a second fabric (fabric 2) was made with a chenille yarn consisting of standard acrylic in the pile and having standard acrylic yarn as the core. This fabric was treated with a fire-retardant latex with a weight of 140 g/m2.
  • Fabric 1 Fabric 2 Chenille pile: standard acrylic Chenille pile: standard acrylic Chenille core: anionic modified polyester Chenille core: standard acrylic Weight of fire-retardant latex: 80g/m2 Weight of fire-retardant latex: 140g/m2 Colour: ecru Colour: yellow Meets BS 5852-1 Fails BS 5852-1 Construction of the two fabrics (weave, density etc.) is identical, with the exception of the chenille core and the colour. The colour is not relevant in the fire tests.
