Definitions

  • the present invention relates to a method for producing a thread from fiber material which, after carding, is stretched, combed, stretched again and then spun.
  • This object is achieved according to the present invention in that a portion is removed from the fiber material after carding and subjected to an analysis with regard to fiber length and / or dirt content, that certain limits for fiber length and / or dirt content are defined and thereafter the comb intensity is determined and that that with these combs combed fiber material, after it has been stretched, is dissolved into individual fibers, which are incorporated into the end of the continuously drawn thread.
  • the fiber material to be spun goes through several stages in which the parallel orientation of the fibers is improved until during the spinning process itself, the fiber material loses its parallel position in a method according to the present invention, since the fiber material dissolves up to individual fibers becomes.
  • the parallel position of the fibers according to the present invention has to be effected again during the fiber transport from a disintegration device to an open-end spinning device and during the Placing the fibers on a fiber collecting surface, that it is advantageous to subject the fiber material to a combing process.
  • the fiber material that is to be spun into an open-end yarn should not be combed out in any way, but with a certain intensity, which depends on the fiber material.
  • the fiber material to be spun is subjected to an analysis with regard to fiber length and / or dirt content after carding, with certain limits being set for the minimum fiber lengths and / or the maximum dirt content.
  • the combing intensity is then determined in accordance with the analysis results obtained and the material is combed with this combing intensity. It has been shown that the achievable improvements in the yarn are too small if the combing-out intensity is too low, ie there are still too many short fibers or impurities in the fiber material. On the other hand, if the combing intensity is too high, the improvement that can be achieved will decline again. There is therefore an optimal range both in terms of expenditure and in the improvement of the yarn properties such as strength, working capacity, tear resistance and tear resistance.
  • the residual content of impurities can be measured in the fiber material after it has been subjected to the combing process, and the combing intensity can then be determined so that this residual content is 0.04 to 0. 02% lies.
  • the yarn loss can be influenced by the condition of the fiber material when it is subjected to the combing process.
  • this regulating process can be carried out at any time before the combing process. However, it has proven to be advantageous if this regulation is carried out during carding and / or stretching.
  • the fiber material 2 to be spun is prepared in a known manner and presented in the form of flakes or a fleece to a card 1 of conventional construction.
  • the fiber material leaves the Card 1 in the form of a sliver 20, which is deposited in a can 10.
  • a sample is now taken from this material so that an analysis 7 is created which will later serve to adjust a combing machine 4.
  • This analysis is carried out, for example, with the aid of a vibrograph, which shows the length distribution of the fibers in the form of a vibrogram (fiber beard curve).
  • FIG. 3 Such a diagram is shown in FIG. 3.
  • the frequency is given in percent on the horizontal axis and the fiber length in millimeters on the vertical axis.
  • the fibrogram shown as an example in FIG. 3 shows that 100% of all fibers have a length of at least 3.8 mm. About 93% of all fibers have a length of over 5 mm and about 88% of all fibers have a length of over 6.5 mm. As the diagram shows, the proportion of fibers in the total amount of fibers becomes smaller the longer the fiber length becomes, until finally no fibers can be found for fiber lengths over approx. 34 mm.
  • the sliver 20 from which a sample has been analyzed, is fed to a section 3, on which the sliver 20 is drawn and duplicated with five or more other slivers 20 by a new sliver 21 of the same thickness , but with a greater uniformity than the sliver 20 presented.
  • This sliver 21 is placed in a can 30.
  • the cans 30 with fiber tapes 21 are now presented to the combing machine 4 in this form or, after they have been brought together with other fiber tapes 21 to form a cotton fleece, to the combing machine 4, where this fiber material is subjected to a combing process.
  • the combing machine 4 can be adjusted according to the analysis result to different comb intensities, which are determined by the combing depths, so that different amounts can be combed out as waste depending on the setting from the fiber material presented. As a result, short fibers, shells, dust and tufts of fibers are excreted from the fiber material to be spun.
  • the sliver 20 originating from the card 1 is fed to the draw frame 3, where this material is warped in the manner described and then presented to the combing machine 4.
  • the combing machine 4 On the combing machine 4, a certain amount of material is combed out as waste in accordance with the setting previously made, the combed material being in particular the undesired short fibers and also undesired dirt.
