Definitions
- the invention relates to a method and a device for fibrillating a web-shaped textile fabric. It therefore belongs generally to the field of textile finishing.
- fibrillation refers to the production of short pieces of fiber, so-called microfibrils, on the surface of the fibers constituting the fabric.
- the microfibrils are the result of mechanical, enzymatic and / or chemical treatment of the textile fabric. This creates a “silk-like” grip.
- the resulting “peach skin” or “patina” gives the fabric improved fall and appearance.
- Various methods and devices are known for fibrillating textile fabrics, e.g. with the aid of granular abrasives, such as sandpaper or diamond paper, or using rotating brushes.
- a process for fibrillation by applying high-pressure liquid to the textile fabric is the subject of WO97 / 19213.
- the high-pressure liquid impinges on the continuously conveyed textile fabric from a large number of narrow openings.
- the manufacture of a nozzle with such openings is complex.
- the small diameter of the openings and their small spacing from one another can cause the bores to stick together due to deposits of salts and contaminants dissolved in the high-pressure liquid.
- the liquid jets emerging from the openings and separated from one another can furthermore lead to an uneven, strip-shaped fibrillation of the web-shaped textile fabric.
- Document US-A-4 152 480 describes a method in which a continuously conveyed sheet-like textile fabric is acted upon by high pressure liquid discharged through a slot die. This is intended to entangle or matt the individual fibers of the textile fabric to produce a nonwoven-like product.
- a similar method with a slot die can also be used to fibrillate a fabric when the liquid is fed to the slot die through a feed line, the cross section of which is substantially larger than the total area of the free passage opening of the outlet slot of the slot die.
- the device according to the invention and the method according to the invention are suitable for all types of textile fibers, or for the textile fabrics made therefrom, but preferably for the gentle fibrillation of fine and lighter fabrics.
- the invention provides that the high-pressure liquid strikes from a slot die as a continuous liquid curtain across the entire width and on at least one side of the continuously conveyed textile fabric.
- a slot die is simple and inexpensive - 3 -
- the shape of the outlet slit of the slot die prevents, due to its larger spatial dimension and its - in comparison to discrete bores - continuous outlet opening, clogging by contamination of the high-pressure liquid.
- Another advantage of the uninterrupted, gap-shaped outlet opening lies in an absolutely uniform liquid curtain with which the web-shaped textile fabric is acted upon. Interruptions in the liquid curtain due to design-related defects in the nozzles do not occur.
- Advantageous fibrillation results are obtained by feeding the liquid to the slot die at a pressure of 25 to 70 bar and supporting the running textile fabric at the point of impact of the liquid with a smooth, preferably impermeable support surface, in particular in the form of a rotatable roller.
- the high-pressure liquid, through which fibrillation is effected can expediently consist predominantly of water, to which additives can be added if necessary. These are said to facilitate or improve fibrillation and are preferably swelling agents for cellulose-containing fibers.
- Alkaline solutions such as e.g. Sodium hydroxide or sodium carbonate solutions.
- the method according to the invention can be carried out particularly advantageously if the liquid mixed with air is fed to the slot die.
- a continuous liquid curtain is preferably dispensed by means of a slot die whose outlet gap for the liquid can be adjusted steplessly in a width between 0.05 mm and 1 mm, preferably from 0.08 mm to 0.15 mm. Bearing the slot die on swiveling arms has also proven to be particularly suitable for achieving an excellent fibrillation result. With this measure makes the angle of incidence, which is spanned between the liquid curtain and the textile fabric, infinitely adjustable. The angle can be approximately in a range from 40 ° to 150 °, preferably 60 ° to 120 °.
- the distance between the outlet slot of the slot die and the point of impact on the textile fabric should preferably not exceed 200 mm, advantageously not greater than 150 mm. This is relevant since too great a distance causes pressure losses of the high-pressure liquid at the point of impact and thus leads to unsatisfactory fibrillation.
- the continuously conveyed sheet-like fabric can be acted upon advantageously if the liquid supply line opens into one end of the slot die and is connected to the other end of a return line for the liquid. With this connection on both sides, the liquid can be conveyed in the circuit, with which an essentially uniform liquid pressure can be achieved over the length of the slot die and any deposits or incrustations can be washed away.
- the cross section of the supply line for the liquid is, according to the invention, substantially larger than the total cross section of the outlet gap.
- the ratio of the area of the pipe cross-section of the supply line of the nozzle to the total area of the passage opening of the outlet gap should be at least 30 to 1 - 5 -
- the device for fibrillation according to the invention further comprises a drive device for guiding the textile fabric under the slot die and a drive and tensioning device for further transport of the textile fabric.
- FIG. 1 shows a schematic vertical section through a machine for fibrillating a web-shaped textile fabric
- FIG. 2 shows a schematic top view of the machine from FIG. 1,
- FIG. 3 shows a schematic representation of a fibrillated fiber, for example cellulose fiber
- Fig. 4 is a perspective view of a circulating slot die
- FIG. 5 shows a schematic representation of a fibrillation device which is operated with a liquid connection on one side.
- the machine shown in FIGS. 1 and 2 contains a rotatable roller 1 with a smooth, impermeable surface, which is moved by a drive motor 2.
- the roller 1 supports and guides a continuously conveyed web-shaped - 6 -
- the continuously conveyed textile fabric 3 is pressurized with high-pressure liquid as a continuous liquid curtain 14 over the entire width of the structure 3 by means of an infinitely adjustable gap 5 of a slot die 6.
- the width of the slot 5 of the slot die 6 is preferably in ranges between 0.05 mm and 1 mm set.
- the distance between the slot die 6 and the guide roller 1 is generally not more than 20 mm and is 8 mm in this exemplary embodiment.
- the liquid is fed to the slot die 6 at a pressure in the range from 25 to 70 bar. The pressure depends primarily on the nature and the transport speed of the textile fabric 3.
- the impact angle. the liquid on the sheet 3, measured between the liquid curtain 14 and the direction of movement of the sheet 3 at the point of impact 4, can be expediently adjustable.
- the adjustability can be achieved, for example, such that the slot die 6 is held on swivel arms (not shown) which can be swiveled about an axis which essentially coincides with the line of incidence 4. By pivoting the arms holding the slot die 6, the slot die can then be adjusted approximately between a position 6.1 - angle of incidence approximately 120 ° - and a position 6.2 - angle of incidence et approximately 60 °.
- the adjustability of the impact angle ⁇ could also be achieved in such a way that the roller 1 is mounted on swivel arms which can be pivoted about an axis which essentially coincides with the impact line 4.
- the angle of incidence is generally in the range from 40 ° to 150 °, preferably in the range from 60 ° to 120 °.
- l is at a distance from the rotatable roller - 7 -
- the machine has means for moving a sheet-like textile fabric 3 in contact with the circumference of the first roller 1 and the second roller 7.
- These means include an inlet drive device 12 with conveyor rollers rotatable by a motor 15.
- the drive device 12 picks up the incoming textile fabric 3 and conveys it widely over the rotatable rollers 1 and 7.
- An outlet drive and tensioning device 13 with a drive motor 16 pulls the textile fabric 3 broadly from the roller 7.
- the interaction of the drive devices 12 and 13 generally produces a movement speed of the textile fabric between 0 m / min. and 30 m / min, preferably between 5 m / min. and 20 m / min.
- the arrangement is such that the high-pressure liquid curtains 14 emerging from the slot nozzles 6 and 8 each strike one of the two sides of the running textile fabric 3 over its entire width and cause fibrillation of the fibers.
- the inlet drive device 12 and the outlet drive and tensioning device 13 can be regulated by the person skilled in the art in such a way that a tensile force prevails in the textile fabric 3 between the two devices 12 and 13, which is approximately between 0 - 8th -
- the positions of the slot die 6 and 8 shown in FIG. 2 correspond to the positions 6.2 and 8.1 in FIG. 1.
- the high-pressure liquid curtain 14 usually consists at least largely of water.
- the water can advantageously serve as a carrier for treatment chemicals, in particular for swelling agents which enlarge and / or soften the fiber surface in the case of natural fibers, in particular in the case of cellulose-containing fiber materials.
- Suitable swelling agents which are present in solution in water are, for example, alkaline solutions (NaOH, sodium carbonate) and alcoholic solutions.
- textile fabrics can be fibrillated, fabrics, knitted fabrics, knitted fabrics, nonwovens, both from natural and from synthetic fibers.
- FIG. 3 schematically shows a fibrillated cellulose fiber C which is part of a textile fabric, not shown here, which has been treated in the manner described. Fibrils F protrude from the fiber C.
- FIG. 4 and FIG. 5 show the rotating roller 1 supporting and guiding the sheet-like textile fabric 3 with a smooth, impermeable surface, which is driven by a drive motor 2.
- the liquid is circulated through the slot nozzle 6.
- the supply and discharge lines 17 and 18 have a diameter range from DN 20 mm to DN 200 mm, and thus a passage area from 300 mm 2 to 30000 mm 2 .
- the ratio of the total area of the passage opening of the feed line 17 to the passage area of the slot die 6 is thus about 100: 1. (The total area of the passage opening is calculated from the length of the opening multiplied by the width of the opening at the narrowest point of the nozzle cross section.)
- the pump 19 With a delivery rate of 750 1 / min, the pump 19 ensures that a sufficient amount of liquid is delivered and impinges on the impact point 4.
- the pump 19 serves to circulate the liquid in the circuit. Water is used as the liquid, which is supplied through a line 20.
- a metering device 21 is connected to the line 20, which metered additives and / or air to the water supplied.
- the slot die 6 is shown with only one-sided liquid supply 17. In this case, the high pressure liquid is not pumped into the circuit.
