Definitions

  • the invention relates to a method and a device according to the preamble of the independent claims.
  • Fibrillatable cellulose fibers in particular Lyocell fibers (such as Tencel fibers) are becoming increasingly popular due to their good dyeing and wearing properties and a large number of finishing options and processes for influencing the "handle".
  • Lyocell fibers such as Tencel fibers
  • “Lyocell” fibers are cellulose fibers produced in a solvent spinning process, the sheath of which can be split by mechanical influence, so that fibrils protrude from the sheath surface.
  • Lyocell fibers With Lyocell fibers, it is customary to initiate fibrillation in the strand treatment. The main factors influencing the tendency to fibrillation are: pH value, temperature and mechanical action. In addition, cellulase enzymes are often used to promote fibrillation. Cellulase enzymes are proteins that are able to break down cellulose. A cellulase enzyme consists of a large number of different enzyme components. The 4 most important are: endocellulase, exocellulase, cellobiohydrolase and cellobiase. The action of exocellulases results in soluble glucose directly from cellulose. The other components systematically attack the cellulose chains by arbitrarily splitting the formation of cellobiose into soluble glucose.
  • the fibrillation of Lyocell fibers can only be achieved by mechanical treatment, in particular by Initiate wet friction.
  • the addition of enzyme serves to promote and control the process. Enzyme processes are also used to weaken and remove the long fibrils after an initial fibrillation. This process is described in detail in "ITB Veredelung, 2/94, p. 5; R. Breier, finishing of Lyocell fibers, chemical fibers / textile industry, 44th / 96th year, November / December 1994, p. 812; Lyocell -Fibers: Manufacture, properties, areas of application in chemical fibers / textile industry, 43rd / 95th year, October 1993, p. 745: I. Marini, Lenzing Lyocell fibers in chemical fibers / textile industry, 43th / 95th year, November 1993, P. 878.
  • the invention proposes to carry out the fibrillation of fibrillatable cellulose fibers such as Lyocell, in particular of textile fabrics containing Tencel fibers, with a wide range of goods. According to the invention, this can be achieved if the wide web of material is acted upon by a liquid stream flowing at high speed and accelerated by it and hurled with the liquid stream against an impact surface and if the acceleration and spinning process is repeated until surface areas of the fibers are split and fibrils form.
  • Fibrillation can be influenced in a known manner by enzyme treatment, temperature and pH adjustment.
  • the invention can be used to primarily fibrillate goods and, for example, in a downstream enzyme process to remove the long fibrils in a known manner by enzyme treatment.
  • the method according to the invention can also be used for secondary fibrillation, that is to say for a fibrillation process which follows a first fibrillation, a subsequent treatment to shorten the fibrils which are too long, and possibly other finishing steps.
  • the material web is accumulated in a goods store and withdrawn from it by the liquid flowing at high speed.
  • the goods lying loose in such a store can be carried along and accelerated particularly well by the liquid flowing at high speed.
  • the web of material is sequentially entrained in the opposite direction by such a liquid stream and is hurled against impact surfaces.
  • the goods would alternately be conveyed “forward and backward” through the guide gap. If the time period for funding in the "forward" direction is longer than the time period for funding in the opposite direction, the result is a "forward" funding.
  • the material web is at a speed of at least 8 m / sec. preferably to a speed of 9 m / sec. up to 15 m / s is accelerated.
  • the velocity of the liquid jet (preferably a water jet) in the delivery gap is approximately 12 to 20 m / s, preferably approximately 15 m / s. is.
  • the method according to the invention for fibrillating cellulose fibers contained in a textile web in particular lyocell fibers (such as Tencel fibers), can be carried out particularly advantageously with a device in which a wide web of material is accelerated in a guide gap through which a liquid flows if the guide gap at least on one side through a nozzle element is limited, which has a feed channel for the liquid and which has an outlet gap narrowing towards the guide gap and a valve element for alternately closing one of the outlet gaps on two opposite sides.
  • each outlet gap tapers in the direction of the guide gap and if the flow axis of the outlet gap is inclined at an angle ⁇ of approximately 10 ° to 20 °, preferably approximately 15 °, to the plane of the guide gap.
  • Fig. 1 shows schematically a Tencel fiber 1 from which fibrils 2 protrude.
  • the Tencel fiber 1 is part of a fabric, not shown, that has been subjected to a treatment according to the invention.
  • a material web 3 is fed to a device for fibrillation 4 via a conveyor roller 5 from a conveyor device, not shown.
  • the conveyor roller 5 continuously conveys the web into a goods store 6. From there, the web 3 passes through the guide nip 7 of an acceleration device 8.
  • the guide gap 7 is delimited by an upper and a lower guide track 9 a and 9 b.
  • Two outlet gaps 10 are provided laterally in the lower guideway, one of the gaps being closable by valve means 11.
  • the outlet gap 10 a is closed, while the outlet gap 10 b is open, while in the exemplary embodiment according to FIG. 3 the outlet gap 10 b is shown as closed.
  • the water flowing out of the outlet column 10b entrains the web 3, accelerates it and hurls it against an impact surface 13, as a result of which the web 3 and the fibers from which the web 3 is made are mechanically stressed.
  • the web of material falls downward from the baffle 13 into a goods store 17, from which it can be transported away by conveyor rollers 14 and 15.
  • valve means can be moved laterally, so that the outlet gaps 10 a or the outlet gaps 10 b are alternately closed. Depending on the outlet gap through which the liquid exits at high speed, the web 3 is thrown either against the impact surface 13 or the impact surface 16.
  • the alternate spinning results in a particularly uniform and effective mechanical treatment of the web for the handle of the goods.
  • Fig. 3 shows an embodiment in which a guide gap 7 is provided both on the top and on the bottom of the web 3 with outlet gaps 10 a, 10 b. Accordingly, two valve means 11 are also provided which close the outlet gaps 10 b in the operating state shown, so that the liquid is fed to the outlet gaps 10 a and the goods are conveyed and accelerated in the direction of the arrow x.
  • FIG. 4 shows a detail of a top view of the guide gap 7 according to FIG. 3, through which the material web 3 is transported through the water conveyed at high speed.
  • the exit gaps 10a and 10b are indicated by dashed lines on both sides. (As stated above, in the exemplary embodiment according to FIG. 2, an outlet opening 10 a is provided only on the underside of the guide gap 7).
  • the number of treatment steps (spinning onto an impact surface), the regulation of the impact speed, and one-sided or mutual treatment allow the degree of fibrillation and thus also the surface quality and the feel of the goods to be influenced in the invention.
  • Upstream and downstream enzyme treatment steps can be used to additionally influence fibrillation.
  • outlet gaps 10 a and 10 b are provided for the liquid, not only can "open-width" goods but also tubular goods be treated, if this is desired.
  • the treatment generally consists of three components: (1) fabric baffle; (2) fabric water; (3) fabric-fabric.
  • the force with which the wet goods are thrown against the impact surfaces obviously depends on both the speed of the conveyed liquid and the length of the acceleration path, any braking effects and the mass of the wet goods at the moment of the impact.
  • forces per centimeter of goods width in the range of 2.5 to 9 Newtons occur on impact.
  • the values are preferably between 5 and 9 Newtons per cm. This leads to particularly good fibrillation results.
  • the invention is particularly effective when used with fabrics which consist entirely of fibrillatable cellulose fibers, such as "Lyocell” fibers (in particular Tencel fibers). However, it is also possible to treat goods that consist of mixed fibers or mixed fabrics.
