Definitions

  • carpets are used in larger quantities Spun yarns (spun yarns) made of polyamide fibers (PA6, Perlon; PA6.6 nylon) made of polypropylene, polyester or other man-made fibers and mixtures of such fibers used.
  • the staple fiber carpet yarns are made from Staple fibers, i.e. spun from fibers of limited length.
  • Spun yarns have the advantage, among other things, that they can be dyed well and evenly and the result manufactured and colored carpets a uniform have a calm appearance.
  • these carpet yarns whether they are natural Fibers or synthetic fibers are strong Have hairiness, i.e. that the ends of the the yarn forming individual fibers are not integrated into the yarn, but protrude from the yarn, so that in a mechanical Attack separated from the yarn or from the yarn can be pulled out: such spun yarns have a strong tendency to fluff.
  • the shift to the filament yarn has taken place although the filament yarns have disadvantages compared to Have spun yarns. They point out because of their structure not the lint problem described, can be but stain worse and don't have as good mechanical properties. You have e.g. a worse one "Resilience" in the event of a break Burden. Made and dyed from filament yarn Carpets have a not level, restless, often streaky product image. Mechanical loads such as Footprints or pressure marks on objects placed or furniture feet are after the pressure has ceased visible for a long time.
  • the invention has for its object a hairy Pre-treat carpet yarn in such a way that it requires little effort and without adverse influence on the mechanical Yarn properties and the dyeing behavior of the fluff can be reduced.
  • the spun fiber carpet yarn is so quickly through a high temperature treatment zone is passed through that the protruding hairs because of their small diameter and their low heat capacity practically instantaneously come to a high temperature and burn, evaporate or sublimate the inner volume of the yarn because of the poor thermal conductivity of the material has no time to heat up significantly.
  • Another advantage of the method according to the invention results from the use of the fibers treated in this way for the production of carpets to be printed.
  • the so far used hairy and fluffy spun fiber carpet yarns had the disadvantage of being made from it Carpets print very poorly or not at all let.
  • the hairiness and the lint attack clogging of the stencils very quickly, and on the other hand no one can on such carpets sharp, smooth printed image can be generated.
  • the thermal treatment method according to the invention can be easily integrated into existing systems.
  • the place where the treatment within the facility is largely selectable.
  • the Treatment in principle after fixation and before Winding operation can be done, but is an implementation the thermal treatment between the creel and the heat setting system is preferred. It can also Temperature treatment as a completely separate operation be used.
  • the treatment can in particular according to claim 2 take place that a sheet of carpet yarn by at least an elongated narrow one, stretching across the carpet flock extending zone with the high temperature becomes.
  • transverse is intended to be an arrangement perpendicular to the carpet yarn share as well as an inclined arrangement, by means of which, if desired, the extension of the Zone of action in the direction of movement of the carpet yarn threads can be enlarged without going to the treatment facility Need to make adjustments.
  • a spun fiber carpet yarn is primarily used for the invention made of fully synthetic material like polyamide, Polypropylene, polyester or the like (Claim 5).
  • the carpet yarn is still inside not significantly affected by the temperature rise and are also significant feed speeds of the carpet yarn from 300 - 800 m per minute (Claim 7).
  • the preferred embodiment of creating one limited high temperature zone through which the carpet yarn is passed through is a scorching device (Claim 8), in which the high temperature by burning Gases is generated.
  • the staple fiber carpet yarn but also in other ways of short-term exposure exposed to high temperature e.g. by means of of a laser.
  • the carpet yarn from unreasonable heating can protect the carpet yarn from heat treatment are moistened (claim 10).
  • the Suitable methods are available in the prior art, e.g. Spraying of foggy moisture, condensation of Steam or the like.
  • the invention is also embodied in use the process of yarn singing for the pretreatment of Spun fiber carpet yarns before they are processed into one Carpet (claim 16).
  • a device for performing the method at which carried out the heat treatment by singeing is the subject of claim 17.
  • the essential aspect here is that the yarn threads in a zone extended in the conveying direction, the Sengkanal, in contact with the burner flames or the hot ones Are burner gases, which makes a flame process possible which only slightly stresses the main thread and predominantly concentrated on the above hairs.
  • the length of this zone should be in Direction of movement of the carpet yarn an extension of maximum ten centimeters to achieve the right balance between sufficient scorching effect and production speed to achieve.
  • the conveying speed of the carpet yarn threads through the zone of very high temperatures is considerable and can be 300 to 800 m / min as claimed in claim 24 is specified.
  • the invention is not treated a single carpet thread, but a bevy of several carpet threads.
  • the height of the singe channel perpendicular to the plane of symmetry 8 to 20 mm (claim 26) and the length of the Sengkanals from the point of impact of the gas mixture jets to to the end of the singe channel 100 in the conveying direction can be up to 300 mm (claim 27).
  • Grooves according to claim 28 are uniformity the gas distribution, in particular across the direction of delivery improve.
  • the burner nozzles expediently have small passages Diameter on, so that there are sufficiently high speeds of the mixed gas jets result.
  • culverts are meant to understand both bores and narrow slots be, the “diameter” of the slots their Transverse dimension should be.
  • the culverts are on one arranged in a straight line, in the case of the slots this with their longitudinal direction parallel to the line are.
  • the culverts can be found advantageously in one of the Width of the yarn sheet corresponding width (claim 29).
  • the embodiment according to claim 30 serves the To minimize the entry of false air at the entrance to the scorching canal. This may be from the rapidly running False air entrained in yarn can cause the combustion process irregular on which the stoichiometric composite gas mixture is turned off.
  • the singe burner can be opened and on the side next to the yarn coulter. This is useful in order to achieve an even singeing result from To achieve the beginning of the yarn run, and larger start-up losses to avoid the yarn.
  • the singe burner is in closed state preheated without yarn. After reaching the operating temperature the yarn run is started and the Singe burner in operation with the yarn set running brought together.
  • the singe burner can be in the Yarn coulter or the coulter is led into the singe burner become. In principle, however, it is also possible Singe burner with the coulter of yarn located in the scorching channel ignite at the start of the thread run.
