Definitions

  • the invention relates to a method and a device according to the preamble of the independent claims.
  • Fibrillatable cellulose fibers especially Lyocell fibers (like Tencel fibers) enjoy good dyeing and Wearing properties and a variety of equipment options and method for influencing the "handle" increasing popularity.
  • “Lyocell” fibers are in a solvent spinning process Manufactured cellulose fibers, the sheath by mechanical Influence is fissile, so from the surface of the jacket Protruding fibrils.
  • Fibrillation in Lyocell fibers is common the strand treatment. Factors affecting the inclination to influence fibrillation are above all: pH value, Temperature and mechanical impact. Also be Commonly used cellulase enzymes to fibrillate promote.
  • Cellulase enzymes are protein substances that are capable To break down cellulose.
  • a cellulase enzyme consists of one Many different enzyme components. The 4 most important include: endocellulase, exocellulase, cellobiohydrolase and cellobiase.
  • the effect of exocellulases results in soluble glucose directly from cellulose.
  • the others Components systematically attack the cellulose chains, by arbitrarily making the formation of cellobiose more soluble Split glucose.
  • EP 535 287 A1 describes a method and a device for improving the grip and surface of textile fabrics and knitted fabrics.
  • the web to be treated will be alternating against a first and a second baffle hurled.
  • the web is conveyed pneumatically, with a feed difference in the back and forth movement causes the web from the device is dissipated.
  • polyester fibers to fibrillate an alkaline aqueous solution.
  • the fibers can be broken open, for example, by that the web of goods through a relatively small opening is forced.
  • JP 701566A it is known to act on fibers to fibrillate with a gas stream.
  • JP 1-298273A it is also known, chemically pretreated cellulose fibers to break up.
  • the invention proposes fibrillation of fibrillatable cellulose fibers such as Lyocell, in particular from Textile fabrics containing Tencel fibers carry out wider goods. This can be done according to the invention if the wide web is reached by a high one Velocity flowing fluid flow and accelerated by this and countered with the liquid flow an impact surface is thrown and if the acceleration and the spinning process is repeated until Surface areas of the fibers are split and up Form fibrils.
  • the invention can be used to primary goods fibrillate and e.g. in a downstream enzyme process the long fibrils in a known manner by enzyme treatment to remove.
  • the method according to the invention can also be used for secondary fibrillation is used, that is for a fibrillation process that is a first fibrillation, a subsequent treatment to reduce the too long fibrils and possibly other equipment steps after is switched.
  • the material web is sequential in the opposite direction from such Liquid flow entrained and thrown against impact surfaces becomes. So it is e.g. conceivable that in a gap promote wide-ranging goods through the flow of liquid, hurling against a baffle, the goods in one Collect goods store, then the liquid flow in the Reverse direction and the goods in the opposite Accelerate direction through the gap and up against one the other side of the gap arranged second baffle to hurl and there the goods back in a store accumulate. The goods would alternate “forward and backwards "through the leadership gap Duration for funding in the "forward" direction is longer than the length of time for promotion in the opposite Direction, there is a resulting "forward” funding.
  • the inventive method for fibrillation in a textile web containing cellulose fibers, in particular Lyocell fibers (such as Tencel fibers) can be particularly perform advantageously with a device in which a wide feed web in one of a liquid through the guide gap is accelerated when the Guide gap at least on one side through a nozzle element is limited, which is a feed channel for the liquid and the one on two opposite sides outlet gap narrowing towards the guide gap and a Valve element for alternately closing one of the Has exit column.
  • Lyocell fibers such as Tencel fibers
  • each exit gap towards the guide gap tapered and if the flow axis of the exit gap approximately at an angle ⁇ of 10 ° to 20 °, preferably about Is inclined 15 ° to the level of the guide gap.
  • Fig. 1 shows schematically a Tencel fiber 1 of which Protruding fibrils 2.
  • Tencel fiber 1 is a component of a fabric, not shown, that one according to the invention Has undergone treatment.
  • a material web 3 a device for fibrillation 4 via a conveyor roller 5 supplied by a conveyor, not shown.
  • the conveyor roller 5 continuously conveys the web into one Goods store 6. From there, the web 3 passes through the Guide gap 7 of an acceleration device 8.
  • the guide gap 7 is formed by an upper and a lower one Guideway 9 a and 9 b limited.
  • two exit gaps 10 are provided on the side, wherein one of the gaps can be closed by valve means 11 is.
  • 2 is the Exit gap 10 a closed during the exit gap 10 b is open, while in the embodiment according to Fig. 3, the outlet gap 10 b shown as closed is.
  • Water flows through the outlet gap at a speed of about 15 m / sec. from that of a feed line 12 is supplied. That from the exit column 10 b flowing water entrains the web 3, accelerates it and hurls it against a baffle 13, causing the Web 3 and the fibers from which web 3 is made, be mechanically stressed. From the baffle 13 falls the web down 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 alternately the exit columns 10 a or the Exit columns 10 b is closed. Depending on what outlet gap the liquid is at high speed emerges, the web 3 is either against the impact surface 13 or the impact surface 16 flung.
  • the mutual Skidding is particularly uniform and for the handle of the goods effective mechanical treatment of the web.
  • Fig. 3 shows an embodiment in which a guide gap 7 on both the top and bottom the web 3 with exit gaps 10 a, 10 b, provided is. Accordingly, two valve means 11 are also provided, the exit columns in the operating state shown Close 10 b so that the liquid Exit columns 10 a is fed and the goods in the direction of the arrow x is promoted and accelerated.
  • Fig. 4 shows a top view of the guide gap 7, according to Fig. 3, through which the web 3 through which transports water at high speed becomes.
  • the exit gaps 10a and 10b are on both sides indicated by dashed lines. (As stated above, the 2 only on the underside of the Guide gap 7 provided an outlet opening 10 a).
  • the number of treatment steps (spinning on one Impact surface), the regulation of the impact speed, by one-sided or mutual treatment in the invention, the degree of fibrillation and thus the Affect surface quality and the feel of the goods.
  • Upstream and downstream enzyme treatment steps can be used to fibrillate to influence in addition.
  • the force with which the wet goods hit the impact surfaces thrown obviously depends on both Velocity of the conveying liquid as well as the length of the Acceleration path, any braking effects and the mass wet goods at the moment of impact.
  • forces per centimeter of fabric width occur Of the order of 2.5 to 9 Newtons. Preferably lie the values between 5 and 9 Newtons per cm. this leads to particularly good fibrillation results.
  • the invention is particularly effective when used with fabrics, which are made entirely of fibrillatable cellulose fibers, such as "Lyocell” fibers (especially Tencel fibers) exist. It but it is also possible to treat goods made from mixed fibers or blended fabrics.
