Definitions

  • ABSTRACT A process and an apparatus for the application of Iiquid freshening, brightening or finishing agents to textile threads or yarn, in which a free-falling jet of liquid is directed onto the threads with the additional use of reduced pressure.
  • PROCESS FOR APPLYING LIQUID FRESHENING AGENTS TO TEXTILE THREADS PRIOR ART It is known to dress or finish textile threads with liquid freshening agents by passing the threads over rollers which dip into a bath of the agent and transfer the liquid to the threads.
  • This method of application has two significant disadvantages. On the one hand, it only partly succeeds in uniformly applying the agent to the threads. On the other hand, it has the intrinsic operational defect that, due to the high speed of the threads, the liquid is thrown off both directly behind the rotating rollers and also behind each place where the threads alter their direction; and thus the liquid can readily contaminate the machine. This disadvantage can only be avoided by an uneconomically slow rate of travel of the threads.
  • the present invention relates to a process and for the application of liquid freshening, brightening or finishing agents to textile threads or yarn, in which a freefalling jet of liquid is directed onto the threads with the additional use of reduced pressure.
  • the invention first of all relates to a process for the application of liquid freshening agents to textile threads, or yarn in which the agent in the form of a regulatable, free-falling jet of liquid, the diameter of which corresponds approximately to the diameter of the thread, is directed onto the threads which pass over a vacuum nozzle connected to a vacuum of to 400 Torr and arranged coaxially to the jet of liquid, and the axis of the liquid jet is almost perpendicular to the axis of the thread.
  • the present invention is directed to a process for applying a liquid finishing agent to textile threads or yarn comprising directing a regulatable, free-falling jet of liquid finishing agent onto a moving textile yarn, the diameter of said jet corresponding approximately to the diameter of said yarn, passing said yarn over a suction zone maintained at a vacuum pressure of from about 10 to 400 Torr, said suction zone having an outlet arranged coaxially with said jet of liquid finishing agent, and the axis of said jet being approximately perpendicular to the axis of said yarn; and recovering said textile yarn finished with said liquid agent.
  • the present invention provides an apparatus for applying a liquid finishing agent to a textile thread or yarn according to the process of the invention comprising means containing a supply of liquid finishing agent; a nozzle means having an outlet for discharging said finishing agent onto a textile yarn and connected to said containing means, said discharge nozzle means mounted at approximately a right angle to the travel of said yarn, said outlet of said discharge nozzle having a diameter corresponding approximately to the diameter of said yarn; a regulating valve connected in series between said containing means and said discharge nozzle; and a suction means having an outlet positioned coaxially with said discharge nozzle at a distance below said discharge nozzle of about i to 10 times the diameter of said yarn, said suction outlet having a diameter about 0.5 to 2 times the diameter of said yarn, said suction outlet having a guide means over which said yarn passes and being connected to a vacuum means.
  • the present invention has the advantages that the quantity of freshening agent to be taken up by the threads can easily be adjusted in operation before its issue from the nozzle by the corresponding regulation in the flow rate of the liquid flowing, by alteration of the cross-section of the supply pipe.
  • the regulatable vacuum additionally causes a corresponding alteration in flow rate of the freshening agent flowing from the supply pipe. Further, excess liquid is at the same time withdrawn by the vacuum into the suction nozzle and is therefore prevented from being splashed uncontrollably by the thread moving past at high speed. The liquid is sucked through the multifilament yarn; and consequently a very uniform distribution of the liquid throughout the cross-section of the yarn is attained.
  • a suitable apparatus comprises a storage tank container for the product and devices for the feeding and the removal of the freshening agent.
  • the apparatus according to the invention has a first nozzle for directing the freshening agent, fixed at approximately a right angle, or perpendicular, to the yarn, and connected in series to a regulating valve.
  • the outlet diameter of this nozzle corresponds to about the diameter of the yarn.
  • This vacuum nozzle has a guide means over which the yarn travels; this vacuum nozzle is connected to a vacuum source, such as a suction pump; and the vacuum nozzle has a diameter which corresponds to about 0.5 and 2 times, preferably 1 to 2 times, the diameter of the yarn.
  • the freshening agent flows through the supply pipe 1 to the nozzle 2.
  • the amount supplied is adjusted by a regulating valve V.
  • the nozzle 2 is mounted in a position at right angles to the path of the yarn 4.
  • the diameter of the outlet 3 of the nozzle 2 corresponds approximately to the diameter of the yarn 4.
  • the suction nozzle is coaxial with the nozzle 2, and the distance between the two nozzles 2 and 5 is about 1 to times the diameter of the yarn.
  • the suction nozzle 5 contains the yarn guide 6.
  • the nozzle 5 is connected to a source of vacuum.
  • the diameter 7 of the suction nozzle 5 is somewhat larger than the diameter of the yarn 4.
  • the jet of liquid discharged from the nozzle 2 falls freely onto the yarn 4.
  • the vacuum in the nozzle 5, which is adjustable to between about 10 and 400 Torr, and preferably between to 50 Torr, then pulls the freshening agent through the yarn 4 and thereby ensures a uniform distribution of the agent throughout the cross-section of the yarn.
  • the generally known freshening or finishing agents are used, which have known formulations.
  • suitable agents include the following: sulfated or sulfonated derivatives of fats, oils, fatty acids or fatty alcohols; adducts of ethylene oxide or propylene oxide to fatty acids, fatty alcohols, alkyl phenols, glycols etc.; starch, polvinyl alcohol, polyacrylic acid and other polymers.
  • These agents are applicated water, oils or organic solvents, e.g. mineral oil, chlorinated hydrocarbons etc.
  • the solutions should have a viscosity of 2 to 500 cP.
  • the yarn passes over guide 6 of nozzle 5 which constitutes a suction zone at a speed between 500 and 2000 meters/min, preferably between 800 to 1000 meters/min, with the amount of freshener agent splashed or lost from the system being very minute, for example being less than 1% of the total agent utilized, and preferable less than 0.5% of the total agent utilized.
  • the amount of freshener agent taken up by the yarn will vary depending on the flow rate, visocity and surface tension of the jet of freshener agent and the speed of the yarn.
  • the freshener finishing agent was discharged and directed onto the yarn in the form of a free-falling jet of liquid.
  • the diameter of the jet corresponded to the diameter of the yarn.
  • the yarn was itself passed over a suction nozzle which was connected to a vacuum of 25 Torr.
  • the suction nozzle was arranged coaxial to the jet of liquid.
  • the axis of the jet of liquid and the axis of the yarn were perpendicular and enclosed an angle of
  • the finishing agent was essentially uniformly distributed over the cross-section of the yarn after the treatment.
  • the yarn could immediately be further processed.
  • the machine was not contaminated by splashing of the finishing agent.
  • a process for applying a liquid finishing agent to textile threads or yarn comprising directing a regulatable, free-falling jet of liquid finishing agent of a first diameter and having a first axis onto a moving textile yarn of another diameter and having another axis, said first diameter of said jet corresponding approximately to said another diameter of said yarn; passing said yarn over a suction zone maintained at a vacuum pressure of from about 10 to 400 Torr, said suction zone having an outlet arranged coaxially with said jet of liquid finishing agent, and said first axis of said jet being approximately perpendicular to said another axis of said yarn; and recovering said textile yarn finished with said liquid agent.
  • An apparatus for applying a liquid finishing agent to a textile thread or yarn comprising means containing charge nozzle at a distance below said discharge nozzle of about 1 to 10 times the diameter of said yarn, said suction outlet having a diameter about 0.5 to 2 times the diameter of said yarn, said suction outlet having a guide means over which said yarn passes and being connected to a vacuum means.
