Definitions
- the present invention relates to the field of synthetic fibers as they are usually for the production of paper machine felts, especially of Paper machine felts for use in the press area of paper machines be used. It concerns a core-sheath bicomponent fiber which too essential parts made of polyamide. It also affects use of such a fiber for the production of paper machine felts.
- Press felts serve to support the paper mass in paper machines and absorb water from the paper pulp during the pressing process. This usually happens in the paper making process immediately after Headbox and the Fourdrinier section, and before the paper web in the dryer section is completely dried.
- press felts are made almost exclusively of polyamide 6 (PA 6) or PA 66 fibers and monofilaments, but felts made from PA 11 are also used in the literature Fibers (EP 0 372 769), and PA 12 fibers (EP 0 287 297) etc. are described.
- PEEK polyether ether ketone
- PTFE polytetrafluoroethylene
- EP 0 741 204 describes the use of core-jacket bicomponent adhesive fibers described for press felts, which are primarily designed to the surface quality, the running properties of the felt, the recovery and to improve drainage. This happens through sticking, which by Melting the jacket component are generated.
- the invention is therefore based on the object of providing a fiber which, processed into a paper machine felt, for example, is sufficient Has abrasion resistance and at the same time high temperatures, in particular under the conditions that occur with Impulse Pressing, withstands without to be compacted and glued.
- a fiber of the type mentioned by the Fiber is formed as a core-jacket bicomponent fiber, which has a core and has a jacket at least partially enclosing the core, and in that the sheath consists of 45-98% by weight of a first polyamide, which has a melting point of more than 280 ° C, and 2 - 20% by weight of one Contains layered silicates.
- the core also consists of a second polyamide.
- the coat also contains up to 35% by weight of this second Polyamides.
- the essence of the invention is therefore the fiber as a core-jacket bicomponent fiber build up, and by a layered silicate containing and refractory mantle both to prevent the compaction as well as a Achieve high abrasion resistance by storing the silicates caused reduction in the strength of the fiber but thereby preventing a solid core is present.
- the core is made of a second polyamide and the sheath also contains up to 35% by weight of this second polyamide contains an intimate connection between the core material and the Jacket material ensured.
- a preferred embodiment has the feature that at least the core or the jacket or both parts contains up to 1% by weight of heat stabilizers, and that especially these heat stabilizers hindered phenols, Phosphonic acid derivatives, phosphites or combinations of these stabilizers are. This is another effective measure to increase heat stability and thus to prevent the two-component fiber from compacting.
- the invention claims the use of such fiber according to the invention for producing a paper machine felt, especially a needled paper machine felt, which is still preferred for use in the press area, especially for impulse pressing or is designed for hot pressing.
- the core is preferably made of PA 6 or PA 66 with a relative solution viscosity from 2.4 - 5.0 (1 g polymer per 100 ml 96% sulfuric acid at 25 ° C) or from Mixtures of appropriate PA 6 and PA 66 qualities in a ratio of 1:99 to 99: 1 manufactured.
- Polyamides of the types PA 11, PA 12, PA 69, PA 610, PA 612 or PA 1212 with a relative solution viscosity of 1.6 - 2.8 (0.5 g polymer per 100 ml m-cresol at 25 ° C) are used.
- the core should preferably contain 0-1% by weight of heat stabilizers, e.g. based sterically hindered phenols, phosphonic acid derivatives or phosphites or Combinations of these stabilizers.
- the core thus provides the necessary strength the fibers, for example when they are processed into felts.
- the jacket should be made of a polyamide with a melting point of at least 280 ° C, and it should also contain 2-20% by weight of layered silicates (e.g. MICROMICA® MK 100 from CO-OP Chemical CO., LTD. Japan) and 0-35 % By weight of the polyamide type from which the core is constructed.
- Suitable Polyamides with a melting point of at least 280 ° C are e.g. PA 46, PA 46 / 4T, PA 66 / 6T, PA6T / 6I, PA 9T, PA 10T, PA 12T and 2-methyl-1,5 pentanediamine T / 61 (MPMD T / 61), these polyamides up to 20% by weight of other monomers such as.
- Caprolactam or Laurinlactam can contain.
- the coat contains each also 0-1% by weight of heat stabilizers, e.g. sterically based hindered phenols, phosphonic acid derivatives or phosphites or combinations of these stabilizers.
- the layered silicates can either be compounded can be incorporated into the polymer by means of a twin-screw extruder or but in the polymerization of one of the PA components right from the start Polymerization can be added, which enables better distribution.
- additional adhesion promoters such as Amino silanes are used.
- the core can be surrounded concentrically or non-concentrically by the jacket.
- a non-concentric core-shell distribution can be achieved by suitable spinning and Stretching conditions a helical crimp can be generated.
- the mass ratio of core to cladding is between 30:70 and 70:30, but other component ratios are also possible.
