Description
~ i HO~ 71~F 054 The present invention relates to a process for the dyeing or prin-ting o~ polyester fibers.
From German Auslegeschrift No. 24 33 662, a process for the dyeing ar.d finishing of textile goods has already been ~nown, in which the goods impregnated with dyestuff are exposed to methy-lene chloride. This process is characterized in that for the dyeing and Iinishing of textile goods of polyester fibers, the dyestuff and/or the application agent are applied in an aqueous solution or dispersion onto the textile goods, which are then ex-posed to an air current enriched with methylene chloride. The advantage o~ this method is to be seen in a dyeing process at room temperature up to a maximum of 30 C under atmospheric pressure. In this process, only gaseous methylene chloride is used, which involves certain problems, however, with regard to the toxicity of methylene chloride. ~ccording to the state of the art, a relatively long dwelling time is partly required in the ater-treatment.
It has now been found that materials w~ich consist of,or contain, polyester or polyamide fibers or filaments can he padded or printed by bringing the materials which have at first been padded or printed in common manner with aqueous baths or printing pastes of soluble or dispersed dispersion dyestuffs and have then optionally been dried, in order to fix the dyestuffs with methy-lene chloride, nto a close contact with an accompanying material contalning ~ethylene chloride, or bonding said goods on one side with an accompanying material which is then moistened with methy-lene chloride, and thereafter allowing the materials to dwell at temperatures o~ up to 41 C in either case.

~i L28~1 _ E 77/F 054 cess of the in~ention requires a shorter dwelling time, while resulting at the same time in an improved recovery of the methy-lene chloride used, together with the simultaneous reduction of sealing problems which might occur in the process. Besides, the novel process pexmits to dye or print not only polyester fibers, but also polyamide fibers, each also in admixture with other fibers.
According to the process of the invention, dyeings are ob-tained which are equal or even superior to more expensive processes with regard to the apparatuses and the energy required, for ex-ample the thermosoling or the high-temperature processes, as far as the dyestuff utilizatIon and/or the color depth and fastness properties are concerned.
In accordance with the process, all water-;nsoluble disper-sion dyestuffs, optionally in admixture with one another, maybe used. The dyestuffs of this kind originate for example from the series of the azo~anthraquinone, quinoph*halone or benzothio-xanthene dyestuffs, the azo dyestuffs optionally being used in a metallized as well as in a metal-free form. Dyestuffs of the above-mentioned categories have been sufficiently known and have been described ~n COLOUR INDEX, third edition (~971), volume 2 under the classification of "Disperse Dyes"~
The polyester L ibers dyed or printed by way of the process according to the invention may, for example, consist of the follow-ing polyesters: Polyethylene terephthalate, polycyclohexane-di-methyl terephthalate, heterogeneOus polyesters, for example those of terephthalic acid, isophthalic acid and ethylene glycol, or those of sulfo-isophthalic acid and ethylene glycol, furthermore, ~3 copolyether esters of p~oxybenzoic acid, terephthalic acid and ,, . ,: :, .:- , :
:
. ..
-: , ~ :~1;Z811 ethylene glycol, as well as polycarbonates. According to the process of the invention it is possible to dye or print also those polyester fibers which can be dyed at boiling temperature without carriers. Polyester fibers of this kind are obtained, for example, by incorporating aliphatic dicarboxylic acids, for example adipic acid, or diol compounds having a longer chain, for example, polybutylene terephthalate.
The process of the inv~ntion is also suitable for the dye-ing or printing of synthetic polyamide ~iber materials. This fiber material has been sufficiently known to the man skilIed in the art.
In those embodiments of the process in which two materials may be wound up together for the dwelling, the accompanying material which is impregnated with the methylene chloride may consist of different materiais. If the "accompanying material"
also consists o~ polyester fibers, it is dyed in the same manner as the material impregnated with an aqueous dyestuff dispersion.
As "accompanying materials" there may also be used those of other fibers, for example, native and regenerated cellulose fibers, wool or glass fibers. Besides, it is also possible to use as "accompanying material" paper, for example, highly ab-sorbent filter paper. The material to be dyed or printed is preferably present in the form of a fabric. However, the material may be present in any possible form, for example, in th~ form of knitted fabrics and non-woven fabrics or strands of filaments.
The dwelling temperatures are normally about 10 to 20 C

ing point or be above this point. ~ormally, a temperature in the range of from room temperature to the boiling point is appl~ed.
However, temperatures of 0 C or less than 0 C are also possib-le.
The dwelling period is in the range of from 5 minutes to 24 hours. The higher the dwelling temperature, the shorter is the dwelling period required.
The process of the invention may also be designed in a way that a sheet permeable for methylene chloride, for example a polyethylene sheet, is inserted between the material and the accompanying material. The test of a sheet for its permeabili-ty for methylene chloride is already known and does not have to be particularly mentioned. In the present case it may ~e deter-minated in a very simple manner by sealing the textile material which has been impregnated with dyestuff and which is moist with water in a sheet bag and allowing it to dwell in methylene chlo-ride vapor. The fixation of the dyestuff indicates a permeabili-ty for methylene chloride.
By a material bonded with an accompanying material there is also to be understood a material which consists of at least 2 layers which have been bonded firmly with each other, includ-ing a material which h~s been given a design due to its textile structure, in which one face consists predominantly of one material, whereas the other side consists predominantly of the other material, as this can easily be achieved by a correspondlng weaving technique. Furthermore, this term covers also a material which has been coated on one side with a sheet or with a plastic material. As examples there may be mentioned carpet materials, g furniture fabrics and coated fabrics.
I~O~ 77/F 054 Generally, carpet materials consist of polyester and poly-amide fibers on the pile or nap face. For the backing, use is made of cellulose fibers or synthetic fibers, for example, jute or polyolefin fibers.
In the case of furniture fabrics. the backing consists ge-nerally of cellulose fibers. The carpet materials or furniture fabrics include also those materials, for example, whose upper side consists of polyester and whose back side consists of poly-amide fibers, or vice v~rsa. Moreover, the term "material bond-ed with an accompanying material" also comerises fabrics in which the warp and weft threads consist of different fibers, the fabric structure being designed in such a way that one side con-sists for the most part of polyester and polyamide fibers which differ from those of the other side~
It has indeed al-ready been known from the state of rhe art that for the dyeing and finishing of textile mat~rial of poly-ester fibers, the textile goods are exposed to an air current enriched with methylene chloride after the impregnation witn the aqueous dyestuff solution or dispersion, however, it could not have been gathered from this teaching that the claimed process would be successful, for it was to be expected that due to the close contact of the material to be dyed or printed with the liquid methylene chloride not being present in the gaseous phase, there would not be an even penetration of the material, which would have resulted in an uneven or not thoroughly dyed material, the more so as in the winding up process the accompa-nying material serving as carrier for the methylene chloride is subject to different pressures depending on the positîon 29 within the skein, which leads to different diffusion of the - : :
~o~ 77/F 05~
methylene ~hloride, i.e. amounts of methylene chloride are sup-plied to the material which differ from one place to another.
Nevertheless, an even appearance of the goods is obtained.
It was also surprising that in spite of the sheet permeable for methylene chloride, which has been inserted between the material and the accompanying material, an equally good result is ob'ained without a prolongation of the dwelling time.
The padding and printing is effected in accordance with common known methods which have been sufficiently described.
Whereas in the printing process the material is preferably dried intermediately, this additional process step is genera1-ly not necessary in the dyeing process.
In order to bring the material into contact with the accom~
panying material, known methods are applied. In the most simple case, a ha-lk of filaments is ~rapped with an accompanying rabric impregnated with methylene chloride and is stored in a plastic bag (not permeable for methylene chloride)~
In the dyeing of polyester belts or, for example, fire hoses, the impregnated roll can be wrapped easily with the im-pregnated accompanying fabric and be stored in plastic bags.
In the case of multi-color effects and textile printing, the material to be dyed, the accompanying material and the sheet are each unreeled from a roll and are wound up together in a sandwich-like manner onto a roll. Besides this continuo-ls process, the dwelling may take place on an industrial scale discontinuously or continuously by cuttling up the material, for example in screen belt conveying units. The dwelling may ~lso be e~fected in a different manner, for example in festoon 29 dwelling unitsO

~. ~ . . . -. .
~128~ 1 The insertion of a shee~ is recommended in particular for materials with multi-color effects, in which a soiling or run-ning of the dyestuffs is to be avoided.
In the case of a material bonded with an accompanying ma-terial the moistening of the accompanying material is effected, following the impregnation with the dyestuff, by means of the common techniques, such as slop-padding, spraying and foam-ing.
The padding liquors-or printing pastes to be applied in the . .
process of the invention have been sufficiently known, and the padding and printing processes are also carried out in accordance with known methods. In the case of mixed fa~rics, the single-bath and the two-bath continuous and discontinuous processes may be applied, as they are common for mixed materials of this kind. The dyestuffs to be used for the respective accompanying fiber are known to the expert. Thus, for example, the follow-ing process falls within the scope of the invention:
~ flat textile material of polyester and cellulose is padded with an aqueous bath which contains the dispersion dye-stuff, the reactive dyestuff, alkali and, optionally, a dispers-ing agent, wetting agent, an electrolyte and/or a thickening agent, then the material is wound up in the wet state into a skein, together with a polyacrylonitrile material which has been padded with methylene chloride, and the covered skein is allowed to dwell over night, for example, while being turned slowly.
~fter rinsing, soaping and drying, a textile material is obtained which shows excellent properties.
