Definitions

  • the present invention relates to backing fabrics for papermaking machine felt with improved properties, preferably improved wear resistance and in particular improved dimensional stability during paper manufacture.
  • Fabrics employed in the forming part consist predominantly of polyester monofilaments.
  • monofilaments of polyamides together with polyester monofilaments in an alternating pick-and-shot arrangement on the machine side are also used.
  • the basic fabrics for the pressing felt or wet pressing felt are produced almost exclusively from polyamide fibres and polyamide monofilaments, preferably from pure polyamide-6 but also from polyamide-66.
  • a nonwoven layer of polyamide fibres is needled onto the base fabrics consisting of polyamide monofilaments in a second processing stage and this layer is thereby mechanically anchored in the said base fabric.
  • Dry screens on the other hand normally consist of polyester monofilaments that are largely stabilised by means of suitable products, for example Stabaxol (a commercial product available from Rheinchemie, Mannheim), against hydrolytic decomposition.
  • Stabaxol a commercial product available from Rheinchemie, Mannheim
  • press felts made from polyamide-6 monofilaments have on account of their high abrasion resistance, compressibility and very good recovery of the felts after passing through the press nip major advantages compared to press felts of other materials, e.g. polypropylene, polyester, wool or other types of polyamide (e.g. PA 6.10, PA 6.12).
  • other materials e.g. polypropylene, polyester, wool or other types of polyamide (e.g. PA 6.10, PA 6.12).
  • a significant disadvantage of these press felts is however the lack of dimensional stability in the event of machine downtimes.
  • the materials polyamide-6 and polyamide-66 absorb up to 10 wt. % of water in a wet environment.
  • the length and thickness of the monofilaments changes with the absorption of water.
  • the change in length means that in the event of malfunctions or downtimes of the papermaking machine due to other causes the felts have a different weight and fabric density in the wet zones than in the dry zones.
  • a disadvantage of these fabrics and of the felt produced therefrom is however the significantly reduced wear resistance when used in papermaking machines compared to fabrics of polyamide-6 monofilaments and felts produced therefrom.
  • the object of the invention is achieved if in the production of the backing fabric there are used combination twisted yarns with 1 to 20 monofilaments of polyamide-6 and 20 to 1 monofilaments of polyamide 6.10, polyamide 6.12, polyamide 11 or polyamide 12 in the warp instead of twisted yarns of polyamide-6 monofilaments.
  • the fabrics produced in this way also have a significantly improved economic utility since the raw materials polyamide-6 and polyamide-66 are industrially more readily available and can be re-used in many recycling systems after economic utilisation.
  • a particular advantage of the process according to the invention is that twisted yarns of an even number of the materials used as well as also an odd number of these materials can be twisted with one another. In this way specific, calculable dimensional changes of the twisted yarns or fabrics produced therefrom can be established and the economic utility can optionally also be improved.
  • Pre-twisted yarns of construction 0.20 mm ⁇ 2 were produced on an Allma Saurer AZB-T type yarn twisting machine at 304 revolutions/metre
  • Pre-twisted yarns of polyamide 6, experimental part V 1, were processed on an Allma Saurer AZB-T type yarn twisting machine to form a balanced annular twisted yarn of construction 0.2 mm ⁇ 2 ⁇ 2 with S 304/Z 260 revolutions.
  • the twisted yarn was then fixed tension-free in a heating cabinet for 5 minutes at 160° C. and cut into pieces of length 1.00 m. The exact length and the weight of the sample pieces was determined. Following this the samples were then stored tension-free for 24 hours in a water bath at 20° C., removed from the water, dried, and the change in length as well as the weight were determined.
  • the abrasion resistance of the twisted yarns was determined by an abrasion test developed in-house. For this, the monofilaments and twisted yarns are drawn cyclically under a defined load over a grinding roller until they break. The number of grinding cycles is a measure of the abrasion resistance.
  • Pre-twisted yarn V 1 and pre-twisted yarn V 2 were processed into an annular twisted yarn as described in comparison example 1.
  • the annular twisted yarn had a proportion of PA 6.10 of 25%.
  • the change in length after wet/dry alternating cycles as well as the abrasion resistance was also determined as described in comparison example 1. The results are summarised in Table 1.
  • Pre-twisted yarn V 1 and pre-twisted yarn V 3 were processed into an annular twisted yarn as described in comparison example 1.
  • the annular twisted yarn had a proportion of PA 6.10 of 50%.
  • the change in length after wet/dry alternating cycles as well as the abrasion resistance was also determined as described in comparison example 1. The results are summarised in Table 1.
  • Pre-twisted yarn V 2 and pre-twisted yarn V 2 were processed into an annular twisted yarn as described in comparison example 1.
  • the annular twisted yarn had a proportion of PA 6.10 of 50%.
  • the change in length after wet/dry alternating cycles as well as the abrasion resistance was also determined as described in comparison example 1. The results are summarised in Table 1.
  • Pre-twisted yarn V 3 and pre-twisted yarn V 2 were processed into an annular twisted yarn as described in comparison example 1.
  • the annular twisted yarn had a proportion of PA 6.10 of 75%.
  • the change in length after wet/dry alternating cycles as well as the abrasion resistance was also determined as described in comparison example 1. The results are summarised in Table 1.
  • Pre-twisted yarn V 4 and pre-twisted yarn V 1 were processed into an annular twisted yarn as described in comparison example 1.
  • the annular twisted yarn had a proportion of PA 6.12 of 50%.
  • the change in length after wet/dry alternating cycles as well as the abrasion resistance was also determined as described in comparison example 1.
  • the results are summarised in Table 1.
  • Example 1 75 25 6.0 2.7 260-320
  • Example 2 50 50 5.2 2.0 250-295
