Definitions
- the invention relates to a process for producing dimensionally stable, low-shrinkage, chemically modified technical polyester yarns by melt spinning at speeds of 600 to 4000 m / min, using a copolymer which contains at least 85% by weight of polyethylene terephthalate and comonomers with an intrinsic viscosity of 0 , 75 to 1.00 dl / g and a total titer of at least 500 dtex and a polyester yarn produced by the process.
- low-shrinkage polyester threads which are also high-strength and low-stretch for technical purposes.
- CH-A-513 992 describes a process for spinning, drawing and heat setting in one operation. This process results in a thermal shrinkage of more than 7% measured at 160 ° C with a breaking strength of at most 80 cN / tex with a titer of about 1100 dtex.
- a yarn with such a high tendency to shrink no longer meets the requirements for the dimensional stability of a tire.
- the breaking strength, thermal shrinkage and initial module must be coordinated with one another within certain limits.
- the object of the invention is to provide a method for producing a yarn with a high initial modulus and a low shrinkage, in particular a yarn with a dimensional stability (DS) greater than 28000 [cN 2 / tex 2 ] by chemical modification of a polyester.
- DS dimensional stability
- R is a saturated or unsaturated linear or branched alkyl group from C 3 to C 10 or a cycloalkyl or aromatic radical having 6 or more carbon atoms
- X OR ', COR' or COOR 'and n is 2 to 4, where R 'is H, CO-alkyl or COO-alkyl or an alkyl group with 1 or more carbon atoms.
- the copolyester can be prepared in a customary manner either by direct condensation of ethylene glycol and terephthalic acid or by transesterification of dimethyl terephthalate with ethylene glycol and subsequent polycondensation of the diglycol terephthalate initially formed.
- the comonomer together with the monomers before the transesterification. Esterification phase or before the polycondensation phase added to the mixture.
- other diols such as diethylene glycol, propane, butane or hexanediol or cyclohexane-dimethanol and in addition to terephthalic acid or.
- dimethyl terephthalate other dicarboxylic acids such as isophthalic acid, adipic acid, azelaic acid, dibenzoic acid, dimer fatty acid, dodecanedicarboxylic acid or.
- dicarboxylic acids such as isophthalic acid, adipic acid, azelaic acid, dibenzoic acid, dimer fatty acid, dodecanedicarboxylic acid or.
- the alkyl esters of these acids can also be used.
- the polyfunctional compound is preferably a polyol with three primary alcohol groups such as 1,1,1-trimethylolpropane or 1,1,2-tris (hydroxymethyl) propane or 1,3,5-tris (hydroxymethyl) benzene, with two primary and a secondary alcohol group such as glycerol, or with four primary alcohol groups such as 2,2-bis (hydroxymethyl-) 1,3-propanediol, also called pentarerythritol, or 1,1,1,2 tetra (hydroxymethyl-) ethane.
- three primary alcohol groups such as 1,1,1-trimethylolpropane or 1,1,2-tris (hydroxymethyl) propane or 1,3,5-tris (hydroxymethyl) benzene
- two primary and a secondary alcohol group such as glycerol
- four primary alcohol groups such as 2,2-bis (hydroxymethyl-) 1,3-propanediol, also called pentarerythritol, or 1,1,1,2 tetra (hydroxymethyl-) ethane.
- the polyhydroxy compounds according to the invention also include products with phenol groups such as 1,3,5-trihydroxybenzene or 2,4,5 trihydroxydiphenyl. These compounds are preferably in the form of acetates, the reaction mixture, to increase their reactivity with the dicarboxylic acid.
- the polyfunctional compound according to the invention can also be a tricarboxylic acid.
- the triester of this tricarboxylic acid is 2,4 ', 5 diphenyltricarboxylic acid, a compound which, depending on the polyester production process, is already present in the polyester in more or less small concentrations.
- tricarboxylic acids are e.g. 1,2,3 butane tricarboxylic acid or 1,2,3 propane tricarboxylic acid, also known as tricarballylic acid, and citric acid, which have an aliphatic radical, and 2,2 ', 5,5' diphenyltetracarboxylic acid and 1,4,8 naphthalenetricarboxylic acid have an aromatic radical .
- the amount of the polyfunctional comonomer in the copolyester according to the invention depends on the purity of the polyester. In a polyester production process, where more or less polyfunctional comonomers are present because of the catalytic, thermal or thermo-oxidative degradation or because of the raw material quality, less of the comonomers according to the invention expediently have to be added in order to produce the yarn according to the invention with the reduced thermal shrinkage.
- a polyester made from pure terephthalic acid requires more comonomer than a polyester made from pure dimethyl terephthalate, because less of the 2,4 ', 5 diphenyltricarboxylic acid formed by decomposition reactions is generally present in the former.
- the polyesters produced without direct addition of the comonomers according to the invention depending on the content of the above-mentioned impurity, already have a reduced thermal shrinkage.
- a polyfunctional comonomer must also be added to the conventional polyesters.
- the concentration of all trifunctional comonomers present varies between 0.01 and 0.20% by weight, based on the polyester.
- a trifunctional compound is therefore preferably used in a concentration of between 0.02 and 0.10 mol%, based on the polyester, and concentrations below 0.01 mol% no longer show the effect according to the invention.
- Difunctional, conformationally fixed comonomers with only two functional groups have also proven to be particularly suitable for lowering the thermal shrinkage and simultaneously increasing the dimensional stability DS.
- Conformationally fixed is to be understood as meaning atomic frameworks whose arrangement or types of bonds are suitable for keeping the relative position of the above-mentioned functions relative to one another constant within certain limits.
- these difunctional compounds must be used in concentrations of 1 to 10% by weight, based on the polyester.
- Representatives of such compounds are 2-methyl-2-butene-1,4-diol and 2,3-dimethyl-2-butene-1,4-diol or other unsaturated aliphatic diols such as cis or trans-2-butene-1 , 4-diol and their derivatives such as 1,4-diacetoxy-butene-2 or unsaturated aliphatic hydroxycarbon- acids such as 4-hydroxycrotonic acid or their derivatives such as 4-hydroxycrotonic acid methyl ester, 4-acetoxycrotonic acid methyl ester.
- Comonomers of aromatic diols are also suitable, such as hydroquinone, 2-chlorohydroquinone, 2,5-dichlorohydroquinone, 2,3,5-trichlorohydroquinone, 2-methylhydroquinone, 2,3-dimethylhydroquinone, 2,5-dimethylhydroquinone, 2,3 , 5-trimethylhydro
- quinone 2,3,5,6-tetramethylhydroquinone, 4,4'-dihydroxybiphenyl, 2,6-naphthalenediol, 1,5-naphthalenediol or their derivatives such as hydroquinone diacetate, 2-chlorohydroquinone diacetate, 2,3,5-tichlorohydroquinone diacetate, 2- Methyl hydroquinone diacetate, 2,5-dimethoxy hydroquinone diacetate, 2,3,5-trimethyl hydroquinone diacetate, 4,4'-diacetoxybiphenyl, 2,6-diacetoxy naphthalene, 1,5-diacetoxynaphthalene.
- hydroquinone diacetate 2-chlorohydroquinone diacetate, 2,3,5-tichlorohydroquinone diacetate, 2- Methyl hydroquinone diacetate, 2,5-dimethoxy hydroquinone diacetate, 2,3,5-trimethyl hydro
- Aromatic hydroxycarboxylic acids such as 4-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, 5-hydroxy-1-naphthoic acid, in particular acetyl compounds and alkyl esters such as methyl 4-hydroxybenzoate, methyl 6-hydroxy-2-naphthoate, 4-acetoxyassoic acid according to the invention can also be used be used.
- the polyester yarn produced by the process according to the invention is characterized by a code number DS of> 28000.
- the prerequisite is that Ft is in the range of 50 cN / tex and 80 cN / tex, preferably from 60 cN / tex to 80 cN / tex.
- Polyester is understood to mean a polymer of at least 85% by weight of terephthalate and ethylene glycol units.
- 6.1 kg of ethylene glycol and 10 kg of dimethyl terephthalate and the comonomer according to the invention are placed in an autoclave.
- 4 g of crystallized manganese acetate are added as the transesterification catalyst.
- the mixture is heated to 230 ° C. for 2.5 hours, during which the methanol released and the excess of glycol are distilled off under normal pressure.
- the following substances are added in succession at 230 ° C.: 3 g of phosphorous acid and 3.5 g of antimony trioxide.
- the pressure is reduced to below 0.5 mbar.
- the comonomer can also be added directly into the polymer melt before the vacuum phase. Depending on the type of comonomer, the vacuum is broken after 3.5 to 5 hours by introducing nitrogen, the polymer melt is discharged from the autoclave, for example in the form of a cable, cooled and the solidified polymer is cut.
- the intrinsic viscosity measured at 25 ° C in a mixture of phenol / tetrachloroethane 1: 1 (according to H. Frind, Faserforschung (1954), page 296) is approximately 0.67 dl / g.
- the granules are then dried in a tumble dryer under a vacuum of 0.5 mbar, first for 2 hours at 150 ° C., then for a few hours at 235 ° C. to an IV which is between 0.80 and 1.02 and stored dry.
- the post-condensation time depends on the type of comonomer and the achievable vacuum and is up to 30 hours.
- the dry granulate is processed on a known spinning machine for processing high-viscosity polyesters and drawing high-strength multifilament yarns.
- 310 ° C melted polyester is extracted from the spinneret with e.g. 192 Continuous threads pressed in a known manner, regularly cooled, converted, provided with a preparation and wound up or directly drawn.
- the undrawn yarn is drawn and wound up several times on hot aggregates in several stages.
- the spinning and especially the drawing can, at different speeds, respectively. integrated or in the split process.
- the heat transfer during drawing takes place via an iron, hot rollers or an oven where the thread is is crystallized oriented and fixed.
- the longitudinal tension under which the thread material is held is sufficient to prevent shrinkage during each stage of the heat treatment and to cause repeated stretching.
- the thread material is given a breaking strength of at least 65 cN / tex and the elongation at break, measured at 25 ° C. on the conditioned thread at an elongation rate of 2.7% D / s, is 8 to 15%, preferably 9 to 12%.
- the thermal shrinkage (TS) is 1 to 5% (measured at 190 ° C.).
- the shrinkage values were determined using a thermomechanical analyzer (thermofilter from TEXTECHNO / Mönchengladbach).
- the thread is first pretreated with a preload of 0.4 cN / dtex for 1 minute at 235 ° C and then the shrinkage of the cooled thread is monitored at a heating rate of 20 K / min.
- the clamping length is 10 cm and the shrinkage value at the desired temperature is e.g. 190 ° C determined from the curve.
- the module is determined from the steepness of the force-elongation curve in the initial area as follows:
- the filament is stretched at a clamping length of 500 mm with a force expansion measuring device (company ZWICK type 1474) at a speed of 2.5 cm / min and the force is registered until it reaches 2 cN.
- the force expansion function (with the exception of a very small thrust piece) is very linear for the filaments according to the invention.
- a polyester with a relatively high concentration was additionally added to the decomposition product A by copolymerization, the polyfunctional comonomer B.
- the influence of the increasing concentration of B is clearly visible in the TS.
- the gain in TS in example 10 is not so great because on the one hand the calculated TS value is already low and on the other hand because the comonomer portion is close to the upper limit.
- the thread was made in an integrated spin stretching process.
- the measured TS is especially lower with the Co-PES than with the Homo-PES with a still relatively small concentration at the polyfunctional compound A.
- the thermal shrinkage in the threads 8 and 9 according to the invention is lower than in the threads 4 and 5 with a little too little comonomer.
- the threads according to the invention also show a smaller change in length with the higher concentration of comonomers during thermal treatment under load.
- Example 16 The procedure corresponds to that of Example 12 or 14 but without using a comonomer. After 2 hours, 3.4 l of methanol or 1 l of glycol developed after a further 30 minutes. The polycondensation lasted 3 hours 50 minutes. The polymer had an IV of 0.70 dl / g and a melting point of 255 ° C. After a post-condensation of 25 hours, the IV was 0.99 dl / g. The properties of the yarns are set out in Table 3 as Example 16.
- the measurement results of the examples are shown in the curves of the single figure.
- the ordinate gives the dimensional stability with the dimension cN 2 / tex 2 and the abscissa the spinning speeds in m / min.
- Example 14 shows the best dimensional stability of 48280 cN 2 / tex 2 with a thermal shrinkage of 1.75% at a spinning speed of 3000 m / min. The results in the entire claimed speed range are above those of the prior art (16).
- the yarns produced by the process according to the invention are preferably suitable as yarns with low shrinkage and high Young's modulus (LSHM) for the production of tire cord fabrics and other technical applications such as for drive belts and seat belts.
- LSHM Young's modulus
