Definitions

  • the invention relates to a method for chemical fixing of wool. Sufficiently fixed yarns are necessary for the wet finishing and later wet cleaning of pure wool cut pile carpets for carpeting. This fixation serves to stabilize the yarn twist and the yarn build-up, in order to thereby prevent undesirable matting of the cut pole during the wet treatment. It is known to fix woolen yarns with sodium hydrogen sulfite by treating the yarns opened on the cheese or as a strand either on the yarn dyeing machine or in continuous plants. In order to achieve the fixing effect, the wool yarns are passed through a sodium hydrogen sulfite solution bath at 85 ° C., rinsed in a warm water bath after a desired retention time, and aftertreated if necessary with a hydrogen peroxide solution. Such a process is in "Chemical fibers / textile industry", 40./92. Volume, September 1990, pages 900 to 905.
  • the invention has for its object to provide a method for the chemical fixing of wool for the production of carpet pieces as carpeting, with which it is possible to achieve a desired fixation of the cut pole of a carpet piece in a carpet piece.
  • This fixation is intended to achieve a desired surface appearance, which should be able to go from a completely uniform, streak-free cut pole to a desired, predefinable surface structure and a desired and predefinable surface appearance.
  • the wool is fixed according to the invention as a knitted fabric and / or cut pile carpet piece.
  • the knitted fabric can be knitted, knitted, rustled or crocheted and must allow the yarn to dissolve from the composite.
  • Methods for chemically fixing wool as knitwear are described in documents GB-A-501 292, US-A-3 062 610, GB-A-1 543 720 and "Journal of the Textile Institute", Vol. 55, No. 10 , 1964, Manchester, GB, pages T512-T515.
  • a knitted fabric or a cut pile carpet piece is fixed according to the invention, the knitted fabric being a preliminary product for the production of a piece of carpet.
  • the knitted fabric can be produced in particular as a knitted tube and is thus fixed. In this way, twine bends and twists are fixed in a targeted and even manner, which later create a corresponding, desired surface appearance in the finished pile pile carpet. For this purpose, the knitted tube is drawn back into the yarn after fixing, which is then used to produce a cut pile carpet piece.
  • the fixation of the yarn in the knitted tube can be more or less strong, depending on whether the carpet piece woven with the yarn fixed in the knit piece is fixed again or not.
  • the knitted piece or piece of carpet can preferably be treated with a sodium bisulfite solution at a concentration of 10 to 100 g / l.
  • the knitted piece or piece of carpet can be soaked by immersing in the bath or by pouring the solution over it if the knitted piece or piece of carpet is to be fixed over the entire surface.
  • a viscous one preferably by means of synthetic polymers, can be used Solution can be used.
  • the treatment with sodium hydrogen sulfite solution can take place at a temperature between 20 ° and 90 ° C, and the knitted piece or carpet piece is rinsed with water after the treatment with sodium hydrogen sulfite solution, whereby cystine bonds are reformed in accordance with the equilibrium reaction and the molecular structure is stabilized again.
  • This effect can be intensified by subsequent treatment with hydrogen peroxide, since this reforming of the cystine bonds is an oxidation.
  • the process according to the invention can be carried out particularly advantageously if the knitted piece or piece of carpet is impregnated with a sodium bisulfite solution at 20 ° to 40 ° C. and then steamed, preferably with saturated steam at 95 ° C.
  • the treatment with the sodium bisulfite solution essentially serves to impregnate the knitted piece or piece of carpet with the solution without the wool having a substantial chemical effect.
  • This chemical effect is achieved by steaming with saturated steam at a temperature of at least 95 ° C, whereby the reaction proceeds faster, more intensely and more evenly, since the steam penetrates into the deepest pores of the knitted piece or piece of carpet and acts at a higher temperature than in a bath is possible.
  • the method according to the invention also results in energy savings.
  • the method according to the invention is preferably suitable for a continuous treatment of the knitted piece or piece of carpet in a continuous process.
  • the knitted piece or piece of carpet can be soaked in a first bath with a sodium bisulfite solution of 10 to 100 g / l at a temperature of 20 ° to 90 ° C., preferably 30 ° to 40 ° C.
  • concentration of the sodium bisulfite solution depends on the nature of the yarn and the desired strength of the fixation.
  • the impregnation with the solution can preferably take place in the padder.
  • the knitted piece or carpet piece is passed through squeeze rollers in order to adjust the content of sodium bisulfite solution in the knitted piece or carpet piece.
  • the knitted piece or piece of carpet then enters a tunnel which is saturated with steam of at least 95 ° C.
  • the knitted piece passes through this steam tunnel or piece of carpet with a dwell time of at least three minutes, after which it is then passed through two successive rinsing baths with squeeze rollers arranged at their outputs, then optionally treated with hydrogen peroxide and finally dried.
  • the knitted piece or piece of carpet can be printed with sodium hydrogen sulfite solution in some areas.
  • a desired surface image can be generated by the area-specific fixation.
  • the application of the sodium bisulfite solution can take place over roller printing rollers, through film stencils or in spray printing technology, the sodium bisulfite solution being adjusted viscous, preferably by means of synthetic polymers, for reasons of printing technology.
  • the area-by-area fixing by printing requires a pre-fixing, either by using yarns fixed in particular in the knitted piece or by previous full-surface fixing;
  • full-surface post-fixing can also be provided, in which case steaming may be omitted if the piece of carpet is treated with a sodium hydrogen sulfite solution of at least 80 ° C., the treatment being carried out by immersion in a bath or by pouring the hot sodium hydrogen sulfite solution over it can be done.
  • a concentration of the sodium bisulfite solution of less than 10 g / l may be sufficient for subsequent fixation.
  • At least one fixing treatment of a knitted piece and / or piece of carpet takes place in the manufacture of carpet pieces as carpeting, regardless of whether fixed yarns are used in the weaving of the carpet piece by known methods.
  • This fixation of the knitted piece or piece of carpet can be carried out in the usual way with hot sodium bisulfite solution and then repeated rinsing in hot water, but the treatment is preferably carried out in the form that the knitted piece or carpet piece is saturated with sodium bisulfite solution at a temperature of 30 ° to 40 ° C. and the actual fixing is carried out by a subsequent treatment with saturated steam or superheated steam, which is then followed by rinsing with water and, if appropriate, a further treatment with hydrogen peroxide.
