Definitions

  • the invention relates to a monofilament of polyamide, especially for flat textile products, for use in paper machines, for instance, as well as a flat textile product, a method for producing same and the use of a method for producing a flat textile product.
  • flat products are used as paper machine covers, e.g., as press felts. Press felts are conducted with the still moist paper web or cellulose web over rolls and through a series of roll pairs and water is removed from the moist web during this passage.
  • the press felt serves not only as a carrying surface for the moist web, but also to absorb the water pressed out of the web.
  • the water accumulating in the conveyor belt-like press felt is removed by dewatering devices, positioned for instance at a point where the paper web is no longer in direct contact with the press felt.
  • the paper web is transferred to a drying section where it is essentially subjected to thermal treatment, and is thereby further dewatered or dried.
  • patent EP 0 784 107 A2 discloses a method for producing a monofilament which contains, in addition to the polyamide, also a maleic anhydride-modified polyethylene/polypropylene rubber at the rate of 1% to 30% by weight, and anti-aging stabilizers at the rate of up to 3% by weight. This is supposed to improve the abrasion resistance and form stability of the industrial use flat product.
  • a cross-linked polyamide block polymer is known from the patents US-A 5,998,551 and JP-A 81 12 052.
  • a method for producing very strong fibers is known from the patent US-A 4,853,164.
  • a paper machine fabric made of polyethylene is known from US-A 4,421,819.
  • a method for producing very strong polyethylene fibers is known from the patent US-A
  • the objective of the present invention is to propose a monofilament of polyamide which features improved mechanical properties, especially with regard to abrasion, strength and proneness to splitting, but also with regard to the modification of properties over the course of time. It is also the objective of the invention to propose a flat textile product, especially a forming wire or press felt, for use in cellulose fiber preparation or paper production, for instance, and a method for producing such a flat textile product.
  • the objective is attained by a monofilament of the type mentioned in the beginning, containing polyamide at the rate of 99.9% to 90% by weight, and a cross-linkage reinforcement agent at the rate of 0.1 % to 10% by weight, the polyamide being at least partially cross-linked.
  • the polyamide is a meltable, spinnable, thread-forming polyamide.
  • the invention provides that the cross-linkage of the monofilaments is not limited to their border regions, but extends across the entire cross-section of the monofilament. In this regard, it is advantageous if no core/mantle effects are observed, of the kind, for instance, that can occur as a result of chemical cross-linkage.
  • the invention provides that the monofilament contains a crosslinkage reinforcement agent at the rate of 0.5% to 5% by weight and in particular preferably a cross-linkage reinforcement agent at the rate of 1% to 3% by weight.
  • TAIC triallyl isocyanurate
  • TAC can be used, for instance.
  • TAIC can be purchased in the market under the name Beta Link Master' from a number of companies, among them Plastic Technology Service Marketing-undmaschines GmbH, Adelshofen.
  • the invention provides that only a partial cross-linkage is effected, because a complete cross-linkage would cause the threads to become brittle.
  • the invention also relates to a flat textile product, especially a forming wire or press felt, for use in cellulose fiber preparation or paper production, for instance, in which at least the warp threads consist of monofilaments having the properties described above.
  • the warp thread which runs in the transverse direction in the finished, possibly endlessly woven felt, is responsible in particular for the dimensional stability of the fabric.
  • the invention also relates to a method for producing flat textile products comprising monofilaments with the properties described above, in which the monofilament is extruded and subsequently drawn and woven, the monofilaments being mixed with a cross-linkage reinforcement agent prior to extrusion and irradiated with electron rays before and/or after the weaving process, by means of which the polyamides are partially cross-linked.
  • the use of electron radiation to effect the cross-linkage entails the advantage that no core/mantle effects are produced, i.e., the monofilaments are cross-linked across their entire cross section and not only in the border region (mantle). The electron rays penetrate the entire monofilament, so that cross-linkage also occurs in the core region.
  • the invention-specific monofilament was subjected to various different treatments, which are described below.
  • the values of the first sample were recorded without activator and before irradiation
  • the values of the first sample were recorded without activator and after irradiation.
  • the values of the second sample were calculated with activator before irradiation
  • the values of the second sample were calculated with activator after irradiation, all of which can be seen in Table 1.
  • Table 1 makes it clear that the threads were not damaged by the irradiation.
  • Figures 1 through 3 describe a further trial in which different polyamide samples were subjected to a hydrolysis test in an autoclave over a time period of 240 hours at 120°C in saturated steam.
  • the tensile force reduction is a measure of chemical damage, caused for instance by longitudinal cracks or by deformation to a polygon.
  • the shrinkages are less than in the samples without activator.
  • the hygral expansion is unchanged and the diameter modification in the sample with activator is much less than in the sample without activator.
  • the cracking resistance of the invention-specific monofilament declined much less sharply.
  • the gradient is a measure of the damage to the monofilament.
  • the gradient of cracking resistance change is less than in the known monofilaments. In this trial, 10 samples were produced of all materials. All samples were removed after 24 hours and tested for strength.
