Definitions
- the invention relates to a method for producing fine monofilaments having improved abrasion resistance of polypropylene with a melt flow index (MFI) 2 3o ° c / 2 .i6 k g of 2-16g / 10 min, a monofilament made of polypropylene with a melt flow index (MFI) 2 3D ° c / 2 . ⁇ g of 2-16g / 10 min with improved abrasion resistance and a titer of 5-20 dtex (0.027 mm-0.053 mm), as well as its use.
- MFI melt flow index
- MFI melt flow index
- Textile fabrics made of polypropylene are gaining increasing interest in the automotive industry, above all because of their relatively lighter weight than other thermoplastic materials and improved resistance to climatic influences and mechanical stress. This calls for particularly fine monofilaments, which enable further weight reduction. Fine monofilaments are to be understood as being less than 30 dtex, in particular less than 25 dtex.
- EP-A-1059370 discloses a process for the production of polypropylene multifilaments for textile purposes.
- a metallocene-catalyzed isotactic polypropylene with a melt flow index, which should be less than 25 g per 10 minutes, is used as the starting material in order to achieve the desired shrinkage properties.
- polypropylene granules with a high MFI value should preferably be used. Only general information is given about the yarns produced. Monofilaments are not described.
- EP-A-0028844 also describes a textile multifilament polypropylene filament yarn.
- the starting polymer is a polypropylene with a melt flow index between about 20 and 60. Under the stated spinning and drawing conditions and during further processing, the problem of abrasion which occurs when processing fine monofilaments has apparently not been determined.
- the object of the invention is to provide an economical process for the production of fine, abrasion-resistant monofilaments made of polypropylene. Another object of the invention is to produce fine polypropylene monofilaments with improved resistance to abrasion during weaving.
- a still further object is to provide the use of a fine monofilament with good abrasion resistance for the manufacture of technical fabrics.
- the object is achieved according to the invention in that a compound consisting of 80 to 99.9% by weight of granules and 20 to 0.1% by weight of an additive is added to the extruder, and the melt is spun at a speed of at least 1200 m / min Air bath cooled at room temperature, stretched to a titer of 5-20 dtex (0.027 mm-0.053 mm) at a temperature of 110 to 150 ° C and wound up. It is important here that the additive is well dispersed in the polypropylene and that no difference can be found in the resulting monofilament. For the first time, it was possible to produce fine polypropylene monofilaments with a spinning speed of 1200 m / min. It has proven advantageous to use modified polyolefins and aliphatic diesters as additives.
- Modified polyolefins in an amount of 4.5 to 15% by weight, in particular 6 to 13% by weight, preferably 8 to 12% by weight, of polypropylene / polyethylene with a melting point> 140 ° C. are particularly advantageous as additives.
- a melting point of less than 140 ° C has the disadvantage of complex metering. At temperatures below 140 ° C, the granules stick in the extruder.
- Use of less than 4.5% by weight and more than 15% by weight of polypropylene / polyethylene results in unsatisfactory abrasion resistance of the monofilament. Surprisingly, no further additives are required in this variant in order to achieve excellent abrasion resistance.
- an impact modifier as an additive.
- Suitable as impact modifiers which do not show any softening up to 100 ° C. and are made from linear styrene-ethylene / butylene-styrene block copolymers or alloys from linear styrene-ethylene / butylene-styrene block copolymer // styrene-ethylene / butylene Biblock are built.
- a plasticizer it is advantageous to use 0.1-0.2% by weight of a plasticizer as an additive.
- Di-iso-nonyl adipate is the most suitable plasticizer.
- a lubricant it is expedient to use 0.05-1.0% by weight, in particular 0.3 to 1.0% by weight, of an lubricant as an additive.
- Metal salts of carboxylic acids, linear or branched hydrocarbons, fluoroelastomers, polydimethylsiloxanes are particularly suitable as lubricants.
- fillers it is expedient to use fillers as an additive. 0.01-0.1% by weight of aerosils and 0.1-1.0% by weight of calcium carbonate have proven to be particularly suitable as fillers.
- the additive consists of a compound consisting of a combination of 2-10% by weight of an impact modifier, 0.1-0.2% by weight Plasticizer, on fillers 0.01-0.1% by weight of Aerosil or 0.1-1.0% by weight of calcium carbonate, 0.05-1.0% by weight of lubricants and 0.1-0.5% by weight of heat stabilizers.
- Sterically hindered phenols, phosphites and phosphonites can be used as heat stabilizers.
- MFI melt flow index
- a melt flow index of less than 2 g / 10 min has the disadvantage that too high temperatures are required during melt spinning, which leads to the destruction of the polymer.
- a melt flow index of more than 16 g / 10 min has the disadvantage that the resulting abrasion resistance becomes insufficient.
- Abrasion resistance with a grade of ⁇ 2 results in a monofilament, which can be easily woven into a textile fabric and results in a surprising cleanliness.
- the monofilament according to the invention has a strength of at least 47 cN / tex with a maximum elongation at break of less than 45%.
- the monofilament according to the invention has a mechanical constant (constante mechanique) of at least 285 cN / tex.
- a fiber-forming monofilament is a polypropylene having a melt flow index (MFI) 2 3o ° C i6 2 k g of 12.0 g / 10 min used in all experiments.
- MFI melt flow index
- Each 5 kg of polypropylene granulate is mixed using tin cans and a tumble mixer. Depending on the additive, mixing was carried out using three different methods. The individual processes are explained under the examples.
- the monofilaments pass through the following organs during the stretching process:
- Thread brake • Drafting unit V1, which is equipped with an additional conveyor or rubber roller. - Without drafting pins.
- the variants are stretched at a stretching ratio of 1: 3.6 and an iron temperature (20 cm) of 130 ° C.
- the take-off speed of the drafting unit V2 is 514 m / min.
- Example 2 (experiments 2-4)
- the granulate mixture consisting of polypropylene and modified polyolefin, PP / PE melting point> 140 ° C, is mixed for one hour.
- the granulate mixture consisting of polypropylene and impact modifier is mixed for one hour.
- an antistatic agent such as 0.1% Atmer 110 (trademark of Uniqema) is advantageous in these mixtures.
- the plasticizer is added to the polypropylene granules, then mixed for two hours.
- a lubricant is added to the polymer in different amounts.
- test 17 contains two different lubricants (0.2 and 0.05%) and Aerosil 0.05%.
- Experiments 18 + 19 are based on three additives
- Trials 2-4 polypropylene MFI 12.0 g / min with PP / PE, mp> 140 ° C as additive; Trials 5-7 polypropylene MFI 12.0 g / min with an impact modifier; Experiments 8-9 polypropylene MFI 12.0 g / min with a plasticizer as an additive; Experiments 10-12 polypropylene MFI 12.0 g / min with a filler as an additive; Experiments 13-16 polypropylene MFI 12.0 g / min with a lubricant as an additive; Trials 17-19 polypropylene MFI 12.0 g / min with a compound as an additive
- Example 1 shows the abrasion behavior depending on the addition of an additive according to Example 2.
- Fig. 1 the course of the curve when adding a modified polypropylene / polyethylene with a melting point> 140 ° C according to. Example 2 shown.
- the pure polypropylene shows a rating of 4 in the abrasion test, which represents unsatisfactory abrasion in the fabric. It is surprising that with an increasing addition, the abrasion up to an addition of 10% by weight can initially be improved and deteriorates again with higher additions.
- the abrasion test is a simple simulation of the weaving process on a test device without weft insertion.
- the monofilaments are guided at a constant speed through the most important elements of a weaving machine, such as reed and healds, which also carry out the corresponding movements.
- the thread speed is 9 m / h, the reed performs 525 double strokes per minute.
- the abrasion behavior is assessed with the ABTER test device as follows.
- CM The mechanical constant
- CM V ⁇ ⁇ F [cN / tex] where D means elongation in [%] and F means strength in [cN / tex].
- the fine monofilaments according to the invention are suitable for the abrasion-free production of screen fabrics for filtration and serigraphy.
