Definitions

  • the invention relates to a method and a system of the type corresponding to the preamble of claims 1 and 4, respectively.
  • the starting point of the invention has been problems which have arisen in the past years during the pretreatment and subsequent dyeing of tufted carpet webs according to the described prior art.
  • finishing agents or spinning oils are used, among other things, as lubricants for tufting the carpets.
  • These finishing agents and spinning oils sit on the carpet and in the conventional dyeing process very often result in uneven dye fixation and thus cloudiness and gray haze on the colored carpet.
  • foam dyeing among other things, the foam has the effect of staining the tips of the fibers particularly well and thus avoiding gray haze and cloudy conditions.
  • the finishing agents and spinning oils on the carpet strip destroy the coloring foam in the damper and a cloudy color is created again.
  • finishing agents or spinning oils, but also their type that causes problems.
  • the invention has for its object to improve a generic pretreatment of a web-like textile having a pole.
  • the pretreatment agent should have a certain time to be able to act. If the pretreatment agent is a rinsing agent, it can dissolve chemicals present on the web during the dwell time and also penetrate well between the fibers, so that the textile material is thoroughly prepared for the action of the dyeing liquid applied later.
  • the invention does not consist in the pretreatment or prewashing of a carpet web itself, but in a special type of application of the pretreatment agent in which the web only comes into contact with a small supply of the pretreatment agent comes, and a subsequent dwell to promote the action of the pretreatment agent so applied.
  • the pretreatment agent can be a rinsing agent in order to remove chemicals present on the web from previous production stages, for example the finishing agents and spinning oils mentioned, but it is also possible to apply other pretreatment agents.
  • dwell times of 30 seconds to 90 seconds are expedient for dissolving and then thoroughly removing chemicals present on the web, such as finishing agents and spinning oils (claim 2).
  • the textile material is prepared for dyeing and wrinkle marks that have arisen from storage are to be removed.
  • the removal of wrinkle marks is not particularly successful when steaming dry goods.
  • the application device forming the first part of the system with a vertical gap closed at the bottom, through which the web is guided from top to bottom, is known per se from FR-PS 1 381 081.
  • the air passage resulting in the dwell phase can be designed in the manner set out in claim 5, while the dewatering device according to claim 6 is expediently formed by a suction gap, because this places less strain on the fiber structure of the pole.
  • the preferred mode of operation is nevertheless to work entirely in the continuous process and to subject the fabric web to the coloring immediately after leaving the damper.
  • the system designated as a whole by 100, is used for the pretreatment of a web 10 from a carpet material having a pole before the dyeing.
  • the web 10 runs in the direction of the arrows through the system 100 and successively passes through an application device A for the pretreatment agent, a dwell station in the form of an air passage B, a dewatering device in the form of a suction device C and a damper D.
  • the application device A comprises a vertical gap 2, which extends over the width of the web 10 and is filled up to a fill level 3 with the liquid pretreatment agent, which is constantly supplied from supply pipes 21.
  • the amount of liquid contained in the gap 2 is only small and is about 25 l at a working width of 4 m.
  • the web 10 is guided vertically downwards through the gap via guide rollers 5, 6, takes up pretreatment agent in the gap 2 and is stripped on both sides by two inflatable tubes 7 which are arranged under the gap and extend across the width of the web and which cover the gap 2 limit and seal down, so that no significant amounts of pretreatment agents down out of the gap 2 be able to walk.
  • the web 10 is then guided over the driven deflecting roller 8, which applies the train required for the web 10 to pass through the gap 2, and a compensator 9 before it enters the air passage B.
  • the air passage B in the exemplary embodiment consists of a series of four upper deflection rollers 11 arranged at the same height parallel to one another and a series of three deflection rollers 12 arranged at a distance below and offset relative to the deflection rollers 11, via which the web in the manner shown in the drawing is performed in vertical loops.
  • the material web then arrives in the dewatering device C, which comprises a suction device 13, which consists of a suction pipe 14 arranged under a horizontal web section and a pressure element 15 arranged above the suction slot.
  • a suction device 16 can also be connected upstream of the suction device 13.
  • the dewatering device C can also comprise a plurality of suction devices 13 connected in series, optionally with spray devices 16.
  • the web 10 is suctioned off in the suction device 13 to a residual moisture of 30% to 70%.
  • the train that is necessary to bring the web 10 between the suction pipe 14 and the pressing device 15 is generated by a downstream driven roller 17.
  • the web 10 then runs through a compensator 18 into the damper D, in which it covers only one upright loop in the exemplary embodiment. After leaving the damper, the web 10 passes through a driven roller 10 in order to then leave the pretreatment unit 100 for the dyeing process.
  • an aqueous pretreatment agent with a chemical content of 0.5 gr / L of detergents and wetting agents is applied in an application amount of approx. 400% of the dry goods.
  • the web then remains in air passage B for about 1 minute. After the suction device, it has a residual moisture of approx. 50%. With this residual moisture, it runs into the damper D, in which it also lingers for about 1 minute. The subsequent dyeing and fixing results in a carpet web without cloudiness and without a gray haze.
