Definitions

  • the invention relates to a process for the continuous preparation of plant stems producing bast fibers, such as flax, hemp, as well as to a preparation installation allowing the implementation of said process.
  • flax and other stems of similar plants have been cultivated on the one hand, their textile fibers and on the other hand their seeds providing oil.
  • the elementary fibers are agglutinated to each other by a pectoligneous complex to constitute the fibrous bundles. These are arranged at the periphery of the stem in the Liberian zone and are strongly adherent to the central woody trunk.
  • Retting consists in separating the fibrous bundles from the woody trunk by biological effect.
  • Ginning consists of stripping the ends of the textile stalks from seeds and seed holders.
  • the main purpose of scutching is generally to separate the fibers from the wood. For this, the stems undergo grinding and threshing operations to break the woods, to make the shives fall or woody debris.
  • Such a device comprises two drums rotated in opposite directions between which the rods continuously advance by pinching between strands of a set of belts, defining the direction of movement of the ply and extending perpendicular to the rods.
  • This device shown in Figures 2 and 3, will be explained below Processes for the separation of fibrous and woody elements from textile plants with bast fibers are already known.
  • the straws which have previously been red, are arranged transversely and are pinched in the middle between two profiled belts, fitted one inside the other, which by their rectilinear displacement successively present the half on the "head” side and the half on the "foot” side. straws on the working parts of the machine.
  • total flax another scouring technique, called “total flax”, has been used for several decades for the scorching of unroasted “green” flax and for scouring of burnt flax.
  • This increase in speed between the mills also causes an axial orientation of the fibers of the web.
  • This technique was also used for reworking the tows.
  • the object of the present invention is to provide a process for the continuous preparation of plant stems producing bast fibers, such as flax, hemp or the like, which makes it possible in particular to overcome the aforementioned drawbacks and in particular to provide a set of fibers clean and divided in particular to be used directly on woolen textile material.
  • bast fibers such as flax, hemp or the like
  • Another object of the present invention is to provide a process for the continuous preparation of the stems of plants which makes it possible to obtain a homogeneous product from different batches of straw, that is to say a product identical to itself over time and regardless of the quality of the stems of the same harvest.
  • Another object of the present invention is to provide a process for the continuous preparation of plant stalks, such as in particular flax or hemp, which makes it possible to work a web continuously. From a heterogeneous sheet of straw, the process promotes homogenization of the product obtained.
  • Another object of the present invention is to provide a preparation installation allowing the implementation of the method of the present invention, which makes it possible to carry out the various treatments such as, in particular, ginning, scutching, cleaning, in line, the web moving through said installation at different speeds depending on the stations.
  • Another object of the present invention is to provide an installation for the continuous preparation of plant stems which makes it possible to obtain a set of fibers of good quality, immediately usable, which lowers the cost price of the treatment and consequently of the spinning.
  • FIG. 1 schematically represents an overall view from above of a plant for the continuous preparation of plant stems according to the present invention.

  • the essential phase of work on said first ply (12) consists in eliminating the seeds and seed holders from the stems in a ginning device (4) capable of working the stems forming said first ply (12) transversely to the direction of advance (13) of said ply (12).
