Definitions
- the invention relates to a process for dyeing fibers of polytrimethylene terephthalate with disperse dyes in an aqueous liquor at or below the boiling temperature of the liquor and the use of the fibers dyed according to the invention.
- Polytrimethylene terephthalate is a polyester that has 1,3-propanediol as the diol component and terephthalic acid as the dicarboxylic acid component.
- Large-scale polyester syntheses can basically be carried out according to two different processes (H.-D. Schumann in Chemiefaser / Textilind. 40/92 (1990), p. 1058ff).
- dimethyl terephthalate is mixed with 1,3-
- a composite fiber made of polyethylene terephthalate and polytrimethylene terephthalate is described in GB 1075689 Bei
- the representation of the polytrimethylene terephthalate is based on dimethyl terephthalate and 1,3-propanediol and titanium tetrabutylate is used as the transesterification and polycondensation catalyst.
- German Offenlegungsschrift 19 54 527 on catalysts for the production of polyesters describes another possibility for catalysis in the production of
- Manganese (II) acetate tetrahydrate is used as the transesterification catalyst and hexagonal crystalline germanium dioxide with a
- These catalysts can also be used to prepare dipolymers from terephthalic acid, 1,2-ethanediol and 1,3-propanediol.
- Catalytic system described Again starting from Dimethyl terephthalate and 1,3-propanediol are added as titanium tetrabutylate as a catalyst. In addition, p-toluenesulfonic acid is added as a promoter so that a higher molecular weight is achieved.
- polyester fibers e.g. B. polyethylene terephthalate fibers
- dyeing Behavioral It is known (Herlinger, Gutmann and Jiang in CTI, chemical fibers / textile industry. 37 J89 . , February 1987, pp. 144-150) that the use of polyethylene terephthalate in textile technology was always associated with certain problems with regard to dyeings.
- polyester can only be used with carriers or under so-called HT conditions - i.e. H. at elevated temperature, e.g. B. 130 ° C in pressure vessels - optimally stain with disperse dyes (Bela v. Falkai in "Synthesemaschine", Verlag Chemie, Weinheim, 1981, p. 176).
- Carriers are special aids that have to be added to the dye liquors in order to enable dye absorption in practice.
- Examples of carriers that can also be referred to as fiber swelling agents include a. o-hydroxybiphenyl or
- Polyester-wool blends (wool cannot be dyed using the HT process) led to the development of carrier-free dyeable polyester fibers at cooking temperature.
- polyester chemically or physically (Herlinger et al. In: Chemical fiber / textile industry CTI 37/89, pp. 144 - 150, in chemical fiber / textile industry CTI 37/89, pp. 806 - 814 and in chemical fiber / textile industry CTI 40/92 , February 1990).
- ether modification was carried out . rtes polyethylene terephthalate.
- polyether blocks consisting of polyethylene glycol (PEG) units were built into the PETP chains, which, because of their mobility, make it easier to pull up the dye.
- PEG polyethylene glycol
- the glass transition temperature is also lower in these types of polyester and the dyeing behavior is significantly improved.
- Polyethylene terephthalate and polybutylene terephthalate granules were produced.
- Dye is added. In any case, the result is light shades with low color intensity. This generally applies to all disperse dyes, including those that have a high diffusion coefficient.
- Dyeing process for polyester fibers in which carrier-free and pressure-free dyeing is carried out with dispersion dyes from an aqueous bath at 25 to 100 ° C.
- this general statement is severely restricted in the description of US 3,841,831, on the one hand on PET fibers, on the other hand to only extremely small amounts of dye in the dyebath, and in addition the dyeing process indicated always includes an additional fixing step in order to allow the dye to penetrate somewhat more deeply to allow in the fiber. All this further supports the fact that the use of PET in textile technology has so far not allowed carrier-free, pressure-free and optimal staining.
- the dyed fibers should always have an increased resistance to dyeing when using the fibers and textile products made therefrom where there can be increased abrasion on the fiber surface.
- PTMT fibers polytrimethylene terephthalate fibers
- the process is carried out without pressure, with the dyeing at a liquor temperature between 20 and 50 ° C is started, the temperature within 20 - 90 min, preferably within 45 min, brought to the boiling temperature of the liquor or to a dyeing temperature which is at most 20 ° C below the boiling temperature of the liquor, the dyeing at least
- Polytrimethylene terephthalate was to be expected.
- Esters are well above 200 ° C. However, the melting points of the esters from diols with odd-numbered methylene groups in the diol are generally below the melting points of the esters with the next higher even-numbered methylene groups in the diol. However, this effect can only be seen clearly with the higher methylene group numbers. In the case of polytrimethylene and polybutylene terephthalate, the melting points are almost identical. Also with regard to the glass transition temperature, which should be as low as possible for good coloring properties at cooking temperature without the addition of a carrier, the prior art did not provide any clear indication of its suitability for carrier-free staining for the polytrimethylene terephthalate. So there is very different information from different authors. G. Farrow et al. in Makromol. Chem. 38 (1960), p. 147 settle the glass transition temperature at 95 ° C above that of polybutylene terephthalate, while in US Pat. No. 3,681,188 for polytrimethylene terephthalate
- Polytrimethylene terephthalate fibers which are obtainable from polytrimethylene terephthalate, which are preferred using a single catalyst, are particularly preferably dyed in the invention
- Titanium compounds for the transesterification and the subsequent polycondensation. It is particularly advantageous here that the transesterification catalyst does not have to be converted into an ineffective form before the polycondensation. Furthermore, the catalytically effective one
- species are only generated in the reaction mixture and it can remain in the polymer at the end of the reaction.
- fibers can be made from the PTMT material obtained by all methods familiar to the person skilled in the art getting produced. This is preferred
- Polytrimethylene terephthalate for fiber production is subjected to a melt spinning process, the polymer material preferably being dried beforehand at temperatures around 165 ° C. to water contents of less than 0.02% by weight.
- the polyester staple fibers obtained can optionally be hot-drawn before dyeing with a stretching system known to the person skilled in the art at temperatures of 110 ° C. (heating mandrel) and 90 ° C. (block heater).
- Disperse dyes are not limited to specific compounds, but rather include all dyes with low water solubility, which are able to dye hydrophobic fibers from an aqueous dispersion.
- the disperse dyestuffs in question are familiar to the person skilled in the art, examples being dyestuff classes of the azo series, amino or aminohydroxyanthraquinones or nitro dyes.
- monoazo dyes which have several nitro or cyano substituents, and heterocyclic azo and
- Polymethine dyes Representatives of these classes of dyes can be used alone or in a mixture of several, representatives of different classes also being able to be mixed with one another, for example to produce green or black shades. Also conceivable in the sense of the invention are dyestuffs for dyeing processes, such as are used in principle for dyeing cotton, in which a diaminoazo compound is dyed by the dispersion process, diazotized on the fiber and turned into black with a suitable coupling component
- Trisazo body implements.
- the invention also includes all so-called coloring variants for disperse dyes.
- the disperse dyes are present in an aqueous liquor. They spread out when staining between the aqueous liquor and the fiber treated with it, such as between two immiscible or limitedly miscible liquids, and finally, if the reaction is carried out appropriately and the substance is selected, are drawn onto the fiber.
- Polytrimethylene terephthalate fibers used a liquor which has between 3.0 and 7.0 g of disperse dye per kg of PTMT fiber to be dyed.
- the liquor used contains between 4.5 and 5.5 g of disperse dye per kg of PTMT fiber.
- the disperse dye amounts mentioned relate in each case to the pure dye contained in the commercial dye.
- dyeing is carried out according to the invention without a carrier without pressure at the boiling temperature of the aqueous liquor or at temperatures below it.
- the boiling point of the liquor can also be above 100.degree.
- the dyeing is carried out according to the invention without pressure, ie without using a special pressure vessel, however, for example in a closed dyeing cup.
- the boiling temperature of a dyeing liquor is generally changed only slightly by the addition of dye and / or auxiliary agents.
- the PTMT fibers are therefore treated at a dyeing temperature between approximately 80 and approximately 110 ° C.
- the treatment temperatures are very particularly preferably between 90 and 100 ° C.
- the dyes in the fiber are particularly advantageously completely dyed under the dyeing conditions according to the invention, in contrast to polyethylene terephthalate fibers, which are dyed only in a ring in comparison under identical dyeing conditions.
- Dyed PTMT fibers obtainable by the dyeing process according to the invention can be used in many ways. Basically, they can be used in all sectors that were also open to previously known colored polyester fibers.
- the dyed PTMT fibers obtainable in a process according to the invention are preferably used for the production of woven fabrics, knitted fabrics or knitted fabrics. Because of the excellent mechanical properties of colored PTMT fibers, especially the high ones Elasticity and restorability are also preferred for use in heavily used textiles or as highly elastic fabrics.

- dimethyl terephthalate (Diol batch D with a 1,3-propanediol content of 99.96%, 0.011% 3-hydroxymethyltetrahydropyran content, 0.005% 2-hydroxyethyl-1, 3-dioxane content, 0.02% carbonyls and 0.04% water content) to dimethyl terephthalate is added 1: 2.25 selected and titanium tetrabutylate comes as 10 wt .-%
- Catalyst solution in n-butanol in a concentration of 600 ppm with respect to dimethyl terephthalate Catalyst solution in n-butanol in a concentration of 600 ppm with respect to dimethyl terephthalate.
- Dimethyl terephthalate, 1, 3-propanediol and the catalyst solution are introduced into the polycondensation apparatus and heated to 140 ° C. under a constant gentle stream of nitrogen. After that Dimethyl terephthalate has melted, the stirrer is switched on and the temperature is raised to 220 ° C. The methanol released during the transesterification is distilled off until the calculated amount is almost reached.
- the pressure in the polycondensation apparatus is gradually reduced and the 1,3-propanediol used in excess and the 1,3-propanediol formed during the condensation are distilled off.
- the temperature is slowly increased to 270 ° C and the pressure is further reduced until finally oil pump vacuum (p ⁇ 0.05 mbar) is reached.
- the end of polycondensation is reached when the dropping rate of the 1,3-propanediol has dropped below 0.5 drops per minute. This information applies to the 2 dm 3 polycondensation plant.
- the agitator motor was used in the 2 dm 3 system as an indirect measure of the progressive condensation.
- the torque is determined as a measure of the progress of the polycondensation.
- the vacuum in the polycondensation apparatus is released and the finished polytrimethylene terephthalate under
- Nitrogen excess pressure is discharged into a water bath with a gear pump, drawn off with a draw-off device and immediately granulated.
- the reproducible temperature control during the synthesis is guaranteed by a microprocessor-controlled temperature program.
- the other conditions such as pressure and stirrer speed are changed manually according to the same time program.
- the predetermined end temperature of the polycondensation apparatus is 240 ° C. This temperature is reached 75 minutes before the end of the polycondensation and then kept constant until the end of the polycondensation. However, as can be seen from FIG. 1, the melting temperature rises to the end of the
- Polycondensation continues continuously up to 267 ° C.
- the heat required for this is not supplied from the outside by the heating, but is generated by the heat of stirring in the apparatus itself.
- the fact that this effect only occurs towards the end of the polycondensation can be explained by the steadily increasing viscosity of the polycondensation melt.
- the weight average molecular weight is determined using static light scattering.
- polymer solutions of concentrations 2, 4, 6, 8 and 10 g / 1 in 1, 1, 1, 3, 3, 3-hexafluoroisopropanol are prepared.

- the preparation overlay is about 0.5%.
- the density of the polymer melt must be known in order to produce defined spinning titers. The same applies to a defined preparation pad:
- polytrimethylene terephthalate In addition to polytrimethylene terephthalate, commercially available polyethylene terephthalate was also spun in the spinning tests.
- the spinning speeds are varied at a spinning titer of 16 tex with 32 individual filaments in the range from 2000 to 5000 m / min.
- the spinning titer is varied at a constant spinning speed of 3500 m / min in the range from 9.6 to 22.4 tex with 32 individual filaments each. This corresponds to a fineness of 0.3 to
- the spinning temperature is varied in the range between 240 and 270 ° C, with the best results being achieved at 250 ° C.
- different spinnerets with nozzle hole diameters of 200 to 350 ⁇ are used for polytrimethylene terephthalate. The best results are achieved with a 200 ⁇ m nozzle.
- the staple fibers obtained are drawn on a stretching system from Diens Apparatebau.
- the stretching factors are chosen so that the drawn fiber has about 25% elongation.
- the mechanical properties of the staple fibers and the drawn fibers made of polytrimethylene and polyethylene terephthalate are listed below:
- Polyethylene terephthalate staple fiber Polyethylene terephthalate staple fiber
- the glass transition temperature of the polymers in aqueous medium is of greater importance for the dyeing behavior of the synthetic fibers.
- DR Buchanan and JP Walters, text. Res. J., 42 (1977), 398 define a color transition temperature.
- the dye absorption of the synthetic fibers is determined as a function of the temperature.
- the temperature at which the dye absorption is 50% of the equilibrium value is defined as the coloring transition temperature.
- the dyeing transition temperature depends on the dyeing time and the dye structure.
- Knitted fabrics made from the following fibers are used for the dyeing tests:
- PET 3500 19.0 1.55 126
- the fibers are knitted on a
- the knitted fabric is washed as follows:
- thermofixed knitted fabrics show the
- Polytrimethylene terephthalate has a greater surface shrinkage than with polyethylene terephthalate.
- the extinction coefficient of the pure dye must be known for the quantitative determination of the dye absorption.
- the cleaning of the above-mentioned disperse dyes is described in detail by E. M. Schnaith (dissertation 1979, Univ. Stuttgart).
- the dyeing temperatures are varied between 60 ° C and 140 ° C.
- the coloring is always started at 40 ° C and the heating rate selected so that after 45 minutes
- the cooling rate is always 1 K / min until the bath temperature reaches 40 ° C.

- the dye content can be determined using the corresponding calibration line.
- the dye content FG in g / kg of goods is determined using the numerical equations:
- Figures 2 and 3 show the dye uptake of polytrimethylene terephthalate fibers as a function of the dyeing temperature in comparison to polyethylene terephthalate fibers.
- the horizontal line marks the amount of dye in the dye liquor based on the amount of substrate used.
- Fig. 2 also shows that at a dyeing temperature of 100 ° C, the entire dye from the dye liquor on the polytrimethylene terephthalate fiber. On the other hand, at a dyeing temperature of 100 ° C, only about 15% of the dye offered is absorbed by the polyethylene terephthalate fiber.
- the dyeing temperature must be increased to 130 ° C in order for the dye to be completely absorbed onto the polyethylene terephthalate fiber. This has the consequence that the bath-exhausting dyeing of the polyethylene terephthalate fiber must be carried out in closed vessels under pressure (HT dyeing conditions).
- C.I. Disperse Red 60 a disperse dye with a higher diffusion coefficient, an almost identical course of dye uptake with the dyeing temperature can be observed as with C.I. Disperse Blue 139.

- Fiber cross sections are obtained by embedding the fibers in acrylic acid esters and cutting them to a thickness of 10 ⁇ m with a Minot microtome from Jung. The cross-sectional images are taken with a Zeiss Axioplan microscope. The authenticity of a dyeing, when the dyed fabric is subjected to abrasion, is higher in the case of dyeing through than in the case of ring dyeing, in which the dye is only embedded in the outer layer of the fiber.
- stains with CI Disperse Blue 139 were chosen because this dye is very has low diffusion coefficients. When using other dyes with higher diffusion coefficients, a full coloration can be expected even at lower dyeing temperatures.
- 6 and 7 show cross sections of polytrimethylene and polyethylene terephthalate fibers which are dyed at 95 ° C. and 120 ° C. with C.I. Disperse Blue 139.
- the titanium dioxide particles with which the polymer granulate used is matted can be seen.
