Definitions
- the invention relates to monofilaments in the form of bicomponent threads Core sheath types which comprise a core which is a liquid crystalline polymer contains, their production and their use in particular for Manufacture of paper machine fabrics.
- a monofilament in the sense of the invention is to be understood as an endless yarn which consists of a single continuous fiber, which is made with or without twist and which have a diameter of at least 0.01 mm, preferably at least 0.08 mm, in particular 0.1 mm and more. It is different from Individual filaments in the form of core sheath threads, which are usually used for textiles Purposes are made, especially by the significantly higher Diameter.
- Monofilaments are mainly used for the production of technical articles, in particular technically used fabrics, in contrast to Multifilament yarns that are made up of fine individual filaments and before used mainly in the textile industry.
- Monofilaments in the form of bicomponent threads of the core sheath type are in themselves are already known and are described for example in EP 0 763 611 A1.
- the core component there is a polyester, whereas the sheath is a polyamide is.
- the polyester of the core can also be a liquid-crystalline polymer.
- the Coat a polymer that promotes adhesion.
- liability is waived still to be desired, so that it is, especially with strong mechanical Stress, to a separation of core and shell component, at least in part, which comes down to the mechanical properties of the products produced in such monofilaments.
- the strengths are too still in need of improvement.
- Multi-component threads of the core sheath type are produced, in which the core is made of an aromatic polyester and the jacket is a semi-aromatic Contains polyamide. Notes on the production of monofilaments can be found in the abstract not to be inferred from this Japanese application; liability also leaves here between the core and the coat left something to be desired.
- Japanese patent application 1992/370 321 also describes monofilaments with an A Component as a core component and a B component as a sheath component described, wherein the B component consists of 80% polycarbonate.
- Bicomponent monofilaments in which the jacket component is made of polyester and 1 - 5% by weight Polycarbonate are not described in this document and are not suggested.
- a core sheath filament is disclosed in Japanese patent application JP-07 / 243,128 described, which has a liquid-crystalline polyester core and a jacket thermoplastic polymer.
- This thermoplastic polymer of the shell forms a so-called Sea component and contains an anisotropic aromatic polyester as so-called island components. That is, the jacket is constructed from a matrix of a thermoplastic polymer, in which contains larger deposits that are not compatible with the matrix.
- the object of the invention is therefore to monofilament in the form of bicomponent threads of the core shell type, which fall over a core which contains a liquid-crystalline polymer and a surrounding this core Sheath, in which the cohesion between the core and The sheath component is very good and does not tend to fibrillate, a very high one Have abrasion resistance and good strength and where the jacket has a has an excellent protective effect on the core.
- the invention further relates to a method for producing this Monofilaments according to claim 12 and the use of the monofilaments according to of the invention according to claims 13 to 15.
- the core and the sheath component are melted separately in the extruder and spun in a one-step process in a bicomponent spin pack. After leaving the spinneret, the emerging monofilaments are below the Spinneret in a shaft, for example with a tempered gas flow cooled. It is also possible to cool the threads with the help of a liquid. The threads are cooled down to a temperature which is preferably at least 0 to 30 ° C below the Glass conversion of the cladding material lies. Spray speed and trigger (the so-called spinning speed) are coordinated so that a Delay of at least 1: 5 to 1:30, preferably 1: 8 to 1:15, is reached.
- the monofilaments are wound up after the spinning take-off.
- tempering is possible to start at 200 ° C and then continuously up to, for example, 270 ° C increase.
- the tempering conditions naturally depend in particular on the jacket material used.
- the maximum temperature should be 20 to 30 ° C are below the melting temperature of the jacket polymer.
- a conventional liquid-crystalline polymer can be used as the core component become.
- a single polymer can be used, but it is also possible to mix several liquid-crystalline polymers. there the mixture should be spun as homogeneously as possible.
- mixtures of purely liquid-crystalline polymers can also be mixtures one or more liquid crystalline and one or more not liquid-crystalline polymers are used.
- Polycondensation products are preferred as liquid-crystalline polymers Base of p-hydroxybenzoic acid and 2,6-hydroxynaphthoic acid, in particular those which are composed of 70 to 80, preferably 72 to 74 mol% of p-hydroxybenzoic acid and 20 to 30, preferably 26 to 28 mole% 2,6-hydroxynaphthoic acid.
- polyesters such as Polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, but also polyethylene 2,6-naphthalate or poly (1,4-bis (hydroxymethyl) cyclohexane terephthalate are used.
- polyesters can be used alone or as a mixture.
- polycarbonates used as a further component are commercially available available; this has proven to be very suitable under the Makrolon trade name distributed product proven. Polycarbonates are suitable in the context of Invention as a sheath component, especially when mixed with other polyesters.
- the Sheath one or more elastomeric polyesters.
- These are in particular Copolyesters based on dicarboxylic acids such as terephthalic acid or their Derivatives and a diol such as 1,4-butanediol or ethylene glycol and one Polyglycol, in particular for example the polyglycol based on Tetrahydrofuran.
- Polytetrahydrofuran butylene terephthalate is preferred.
- This elastomeric polyester can be built up, for example, by polycondensation of dimethyl terephthalate, butanediol and polytetrahydrofuran of the formula HO (CH 2 CH 2 CH 2 CH 2 O) n H.
- n is an average and can take different values, correspondingly high then the molecular weight is in the order of about 600 to about 2,000, especially in the order of 1,000, is advantageous.
- a average molecular weight of about 1,000 corresponds to an average of n 17th
- the sheath of the monofilament bicomponent thread should be essentially homogeneous be, i.e. have no macroscopically detectable heterogeneous structure, such as for example a matrix with embedded discrete islands. With mixtures single-phase mixtures are preferred. For components that are used in the Extrusion temperature itself in two phases side by side is through vigorous mixing, for example intensive stirring, for a corresponding To ensure homogenization.
- Suitable temperature control conditions can be selected by simple preliminary tests in order to obtain optimal properties. It is convenient to temper over a period of time, preferably over several hours, perform.
- the physical properties of the monofilament according to the invention are largely due to the physical Properties of the core determined.
- the main task of the coat is to create the core protect against fibrillation, abrasion and soiling. Furthermore, the Coat the processing and improve the usage behavior.
- the monofilaments of the invention can be advantageous for a whole Use a number of uses, such as manufacturing Fabrics for papermaking, for example for screen fabrics, such as those used in the Sheet forming section, the press section and the drying section of Paper machines are desired, filter fabrics can also be produced Conveyor belt fabric, coated or uncoated.
- the Monofilaments for example, can only be used as weft material but it is also possible to completely remove the tissue from the invention To produce monofilaments.
- Another intended use Fabric is the reinforcement in car tires; made accordingly Fabrics can also be used for screen printing.
- the monofilaments according to the invention were considerable are better protected against fibrillation that they can easily be rewound and both as warp and as weft when used for the production of Fabrics can be used.
- the monofilaments are characterized by a particularly low tendency to creep.
