Definitions

  • the invention relates to a method for treating a fiber mass, such as a woven fabric or a nonwoven, in which the fiber mass is passed through a press shop in which the fiber mass is pressed in at least one press zone through the press jacket surface of at least one press roll by means of a pressing pressure acting on the fiber mass and the pressed fiber mass is impregnated with a treatment fluid, wherein the fiber mass in the press zone is passed through an expansion region in which the pressing pressure in the passage direction of the fiber mass decreases.
  • a fiber mass such as a woven fabric or a nonwoven
  • the invention also relates to a press roll arrangement for treating a fiber mass moving relative to the press roll arrangement, comprising a press roll having a press shell surface, in which a pressing pressure acting on the fiber mass is produced in operation in a press zone, and an impregnation device, by means of which in operation a treatment fluid the fiber mass is supplied, wherein in operation, the pressing zone forms an expansion region in which the pressing pressure decreases in the direction of movement of the fiber mass.
  • press surface is that surface which, as an imaginary or actual lateral surface, delimits the press zone to the upper or lower side of the fiber mass, that is to say the idealized outer surface over which the pressing pressure acts on the fiber mass.
  • a polymeric mass is usually melted or dissolved in a solvent and then drawn through spinners into continuous filaments.
  • various spinning processes such as dry, wet spinning or a combination of dry and wet spinning are possible.
  • the filaments are produced in a spinning machine and deducted from this by means of one or more take-off members, wherein they are simultaneously formed into filament bundles or cables. Thereafter, the filaments are washed in further processing steps and post-treated.
  • the cable drawn from the spinning machine is fed from parallel endless filaments to a cutting device. After leaving the cutting device, a nonwoven fabric is generally formed from the individual staple fibers and deposited on a transport device for further processing.
  • the stacks are produced by stack cutting machines, for example, by dry cutting through the machine described in "Ullman Volume 11, Fasem Manufacturing Process", pages 249-289.
  • Viscose fibers are spun as cellulosic Regeneratfasem usually in aqueous media.
  • a cutting machine consisting essentially of a pair of rollers for the supply of the tow to the cutting apparatus, the actual cutting apparatus and a Stapetfaserabschwemmvorraum.
  • the cutting apparatus pulls the cable supplied by the trigger member by means of a water jet injector to the horizontally rotating cutting blades.
  • the cutting blades remain edged during the cutting process by continuous regrinding.
  • by the water jet supply takes place a first resolution of the staple fiber packages resulting from the cutting process prior to the flooding of the staple fiber packets on the aftertreatment machine.
  • Such a machine is, for example, the company lng. A. Maurer S.A.
  • the aftertreatment of, for example, viscose fibers can or must take place over several treatment steps.
  • the following treatment steps are typically carried out with the supply of a treatment fluid: deacidification, desulphurization, washing, bleaching and washing, antichlorine treatment, water washing and application of lubricant or a grease support.
  • These treatment steps are usually carried out in a device to which the cut staple fiber, also referred to as "flake", passes from the cutting machine via a Einschwemmvoriques to form a uniformly distributed non-woven pad.
  • the device for the treatment of the fiber mass is conventionally designed as a long aggregate, in which the fiber mass distributed in a uniform fleece or fiber mass is conveyed through the individual treatment zone on a transport device.
  • a belt conveyor with, for example, an endless wire belt or an endless wire belt belt, a vibrating conveyor or an eccentric detent conveyor can be used as the transport device.
  • the treatment fluid from the preceding treatment step was removed as completely as possible from the fiber mass.
  • a press roll arrangement which exerts a pressing pressure on the pulp. By pressing the treatment fluid is pressed out of the pulp. In the subsequent treatment step, the pressed fiber mass is then impregnated with the treatment fluid associated with this treatment step. Thus, two successive treatment steps are separated from one another by the press roller arrangement.
  • the press zone In the area in which the pressing pressure acts on the fiber mass, i.
  • the press zone shortly after the point of highest pressing pressure forms an area in which decreases in the conveying direction of the fiber mass of the pressing pressure. This area is called an expansion area.
  • the fiber mass In order to wet the fiber mass with the treatment fluid, conventionally the fiber mass is guided on a transport device below irrigation pans. Immediately after pressing, the treatment fluid is applied to the pulp dripped by overlying sprinklers.
  • DE-A-2 031 475 a device is shown in which fiber material is guided on a water-permeable belt of a conveyor and treated by liquid jets. After the treatment by the liquid jets, the fiber material is pressed out by rolling, then treated again by liquid jets and again pressed out by rolling.
  • the dripping of the treatment fluid causes only uneven impregnation and wetting of the just pressed fiber mass.
  • a spinning solution containing water, cellulose and tertiary amine oxide is extruded into an endless filament and stretched.
  • the filament and staple fibers produced by the NMMO or lyocell method have a high crystallinity or orientation of the cellulosic molecules. Due to these product properties originating from the manufacturing process, Lyocell fibers tend to fibrillate. Fibrillation means that small fibrils separate due to the strong crystallinity and orientation of the circular fiber surface of a single fiber. Fibril formation continues along the fiber axis.
  • the fiber may be treated with chemical crosslinkers which bind the fibrillar elements to the fiber stem.
  • chemical crosslinkers which bind the fibrillar elements to the fiber stem.
  • a crosslinking process is controlled so that the cellulosic fiber cable is impregnated with a chemical crosslinking agent and the crosslinking reaction is initiated by damping at higher temperatures.
  • the crosslinking agents must be introduced homogeneously into the fiber mass after fiber production, the fiber optionally tempered and washed out of the fiber in subsequent treatment steps. In addition, like other non-cellulosic fibers, the cellulosic fiber must be cured and dried.
  • the crosslinking agents tend to spontaneous chemical degradation or hydrolysis reactions, since the chemicals hydrolyze in an aqueous medium or are not stable for a long time. If the reaction parameters - for example, the reaction rate or the reaction temperature - can not be maintained exactly, it can also lead to degradation and decomposition reactions. Therefore, the crosslinking agent must be introduced in closed areas under the most precise possible control of the course of the reaction. Usually, the crosslinking agents require rapid introduction into the cellulose fiber followed by rapid tempering and subsequent as fast as possible leaching of the residual chemicals with simultaneous cooling. During so-called crosslinking, elevated temperatures and basic or acidic liquids act on the pulp.
  • the chemical reaction of the cellulose with the crosslinker proceeds at elevated pH values (for example, about 11-14), thereby causing hydrolysis of the crosslinking agent.
  • the decomposition tendency of the crosslinker can be suppressed by the lowest possible temperatures in the crosslinking bath.
  • the low temperatures can be adjusted in or in front of the squeezing device.
  • the conventional method and apparatus in which the squeezed fiber mass is merely sprinkled with a treatment fluid, is insufficient to precisely control the process parameters, especially with chemically reactive or disintegrating treatment fluids, such as crosslinkers.
  • the object of the invention is therefore to improve the method mentioned at the beginning or the apparatus mentioned at the outset in such a way that the distribution of the treatment fluid, the tempering agent (hot water, superheated steam) is as fast and homogeneous as possible and possibly other heat transfer media) as well as various washing media in the fiber mass and thus an exact process control is possible.
  • the tempering agent hot water, superheated steam
  • the press roll arrangement has openings in the expansion region, through which the treatment fluid is conducted through the press jacket surface into the fiber mass during operation.
  • This solution is simple and has the advantage that the treatment fluid is very quickly and homogeneously distributed in the pressed and compacted and relaxing in the expansion zone fiber mass. Since in the expansion region the pressing pressure decreases in the direction of movement of the fiber mass, in this region the fiber mass sucks the treatment fluid automatically through the press jacket surface. Thus, a uniform and rapid penetration of the pressed fiber mass with the treatment fluid already takes place in the press zone. This makes the treatment process more controllable and easier to control.
  • the solution according to the invention has the further advantage that the overall length of a treatment machine can be significantly shortened.
