Definitions
- the invention relates to a dirt-repellent Monofilament for paper machine screens with one Diameters from 0.2 to 0.7 mm, consisting of at least 85% by weight Polyethylene terephthalate with a viscosity index (V.I.) of at least 96 dl / g and a copolymer, process for the production and its use.
- V.I. Viscosity index
- Dirt-repellent properties for paper machine screens supposed to be wet pollution that too Resistance to hydrolysis presupposes to be understood.
- the Dirt repellency is supposed to serve the cleaning cycles extend a sieve, doing the cleaning work under a high pressure water jet and if necessary under Rubbing is done with a brush.
- Dirt-repellent monofilaments that work simultaneously hydrolysis should become technical Fabrics processed and especially in the dryer section used in a paper machine. Such dryer fabrics are Exposed to temperatures well over 100 ° C and moisture as well as when cleaning increased mechanical stress. Dirt-repellent polyester monofilaments have become not proven to be susceptible to hydrolysis.
- additives in the form of stabilizers was a achieved further improvement in hydrolysis resistance, which, however, for paper machine fabrics Dryer section still not enough.
- the increase the dirt-repellent properties were next to the Addition of additives also by suitable Spin finishes, filament finishing treatments as well Post-treatment on the tissue tried.
- Monofilaments were also made from the copolymer Ethylene tetrafluoroethylene produced, the thermal and chemical resistance are excellent and therefore in chemical process engineering. It dryer fabrics for paper machines are known, which on the Carry such monofilaments and the underlying support fabric made of polyester monofilaments protect against pollution.
- the excellent chemical properties of fluoropolymers however, their insufficient tensile strength and Stretch properties.
- EP-A-0 506 963 is a hydrolysis-stable and dirt-repellent Monofilament known, which consists of a mixture of a Polyethylene terephthalate with a fluoropolymer and unreacted carbodiimide consists. Cabodiimide is used in excess to the monofilament to make it resistant to hydrolysis in the long term. The monofilament is in its structure obviously not homogeneous.
- the fluorine-containing polymer can be in the form of fibrils be distributed in a matrix of PET, but also consist of a core sheath.
- the object of the invention is a dirt-repellent To provide monofilament that is high Claims of a technical fabric in relation to its chemical, dirt repellent, mechanical and abrasion-resistant properties are sufficient and special in the dryer section of a paper machine screen Is used.
- Another object of the invention is a method to provide that the economic Manufacture of dirt-repellent monofilaments allowed.
- the object is achieved in that the monofilament 1.5 to 5 wt .-% of a polynary Copolymers prepared from alkenes and perfluorate kenes, contains and one over the entire cross section has a homogeneous composition.
- a polyester is used that of at least 85% by weight of polyethylene terephthalate consists. It should be emphasized as a particular advantage that the manufactured monofilament over the entire cross-section has a homogeneous composition. It can If necessary, melt 1 to 3% of color pigments be added.
- the copolymers which have from 50 % By weight of ethene and about 50% by weight of tetrafluoroethene, proven.
- the copolymer can be in the form of a Masterbatch, which consists of approximately 50% by weight and approximately 50% by weight Copolymer exists, added to the melt become.
- the dirt-repellent monofilaments have a diameter of 0.2 to 0.7 mm, and consist of a polymer blend Polyethylene terephthalate with at least 85% by weight Polyethylene terephthalate units and 1.5 to 5% by weight, in particular 1.5 to 3.0% by weight of a polynary copolymer, made from alkenes and perfluoroalkenes, consist.
- Polynary copolymers have in particular proven binary systems. These are just through To obtain copolymerization of the individual components. Copolymers of ethene and tetrafluoroethene are due advantageous for their easy availability, being a Melting point in the range between 255 ° C and 275 ° C is particularly useful. Other binary or polynary Fluoroplastics such as modified hexafluoropropylene Polytetrafluorethylene, polyvinylidene fluoride and the like can be used.
- the monofilament is 1.5 up to 5% by weight of the copolymers mentioned Polyfluoroalkylene units, preferably 1.5 to 3% by weight, contains in particular 2 to 3 wt .-%.
- the strength of the monofilaments is higher than 36 cN / tex, in particular 36 to 60 cN / tex with an elongation of ⁇ 44 %, based on the unstretched filament, where as essential feature surprisingly the Dirt repellency is particularly good.
- the dirt repellent is as soiling index with ⁇ 2 after 5 soiling / washing cycles, compared to> 5 in one Polyester filament without copolymers was determined.
- the invention is based on an example and a Comparative example will be described in more detail.
- Hydrolysis-stabilized, highly viscous (VI 96) polyethylene terephthalate is in a known manner at a temperature of 290 ° C via a spinneret with a hole diameter of 1.8 mm with a throughput of 486 g / min melt extruded.
- the extruded monofilaments are cooled in a water bath at 70 ° C. After cooling the monofilaments are spin-treated and with a Draw ratio of 5.25x total, relaxed and at a speed of 100 m / min wound up.
- the resulting thread with a Diameter of 0.50 mm shows after 5 treatments has a soiling index of less than 2 ( ⁇ 2) a strength (Ft) of 37 cN / tex with an elongation (Dt) of 39% and a thermal shrinkage (TS at 160 ° C) of 0.4 %, based on the unshrunk thread.
- the AI values shown in Figure 1 show the influence of successive cycles "Soiling" R / "washing out” + W. There are AI mean values in each case of two cartels after soiling and shown after washing out.
- Curve 1 shows the monofilament thread according to the invention.
- Curve 2 shows a comparison thread made of polyester according to the Technology, i.e. without (II). After (five) 5 soiling / washing cycles are with the inventive Monofilament indexes reached below 2.
- the monofilament according to the invention brings Improvement by a factor of 4 to 5 compared to the status of the technique. It is preferred for use in Suitable for paper machine fabrics.
