Definitions

  • the present invention is concerned with a process and apparatus for space-dyeing polyester or polyamide fibres or threads.
  • US. Pat. No. 3,120,422 discloses a process according to which wound-up cellulosic yarn can be dyed multicoloured shades by injection of aqueous solutions of reactive dyestuffs in such a manner that, after the yarns thus dyed have been woven or knitted, no repeat of pattern occurs on the finished textile material.
  • space-dyeing it is essential that the injected dyestuff solutions are dispersed evenly and as extensively as possible in the bobbin. Due to the fact that among others, the fixation of the applied reactive dyestuffs by allowing the material to dwell at room temperature, is very time-consuming, the method described above permits a low production rate only.
  • the apparatus designed for carrying out the process of the present invention essentially consists of an injection mechanism 1 for transferring the dyeing liquor into the wound package 2 of fibres or threads and of at least one supporting element 3 for receiving the wound-up material While the injection mechanism is installed in a fixed position, the bobbin supports 3 are mounted on transporting equipment, for example an endless conveyor belt 4 which can be put into motion by a motor and which, in operation of the device, is passed through an extended, heatable tunnel 5 having inlet and outlet openings for the goods at the two ends only.
  • transporting equipment for example an endless conveyor belt 4 which can be put into motion by a motor and which, in operation of the device, is passed through an extended, heatable tunnel 5 having inlet and outlet openings for the goods at the two ends only.
  • suitable heating arrangements 6 are installed, e.g.
  • the tunnel is connected with feed pipes for hot air or hot steam.
  • the heating units in the shaft must be spaced such that the radiated heat may penetrate the goods uniformly from all sides.
  • the apparatus is equipped with suitable control elements effecting standstill of the conveyor belt during the injection of the dyeing liquor.
  • the injection mechanism contains as the most essential element a hollow injection needle which has a perforated shaft (for more details see Astrodyed Technical Manual, Astro Dye Works, Inc., Calhoun, Ga. 30703/'USA, page 12, FIG. 14). The length of the needle approximately corresponds to the thickness of the wound package to be treated.
  • the position of the injection needle supporter is rearranged such that the point of the infeed needle can penetrate the package from the outside yarn layer until to a desired site inwards to the core of the bobbin, whereupon the effusion of the dyeing liquor may set in.
  • the flow of the liquor is stopped again by a reversed motion of the needle support.
  • the apparatus described may comprise several injection units being suitably described in the interior of the heating tunnel.
  • the bobbins While operating with the apparatus of the invention the bobbins are placed on a running conveyor belt which, in order to prevent a loss in temperature, passes through a tunnel wherein the required temperatures are produced.
  • the conveyor belt is caused to stop by means of a contact, for example, a mechanical or optical contact, and the hot dyeing liquor is injected. After, the injection mechanism has lifted, the conveyor belt is again put into motion by means of a mechanical contact.
  • the hot dyeing liquor is injected under pressure into the preheated package, at least one selected portion of the wound material.
  • the dyestuff solu tion or dispersion spreads out limited along the injection zone, so that along the yarn of the wound package dyed and undyed areas of varying lengths are produced oc curring at quite irregular intervals.
  • the amount of dyestuff injected may, of course, be varied. It depends on the desired ratio of dyed and undyed yarn.
  • the injection of the dyeing liquor at several locations may be provided separately or simultaneously, for achieving a definite nonrepeating pattern.
  • the injection positions must, of course, be selected in a suitable manner. It is also possible, in order to produce a multi-color spotted yarn according to the invention, to press dyeing liquors of a different shade side by side into the package, either separately in an alternated sequence or simultaneously.
  • solvents or dispersants for the dyestuffs there may be used in the instant process oxalkylation products of aliphatic, alkylated aromatic, aromatic or cycloaliphatic compounds containing at least one free hydroxy group in a terminal position.
  • Suitable compounds of said type are the oxalkylation products of fatty acids, fatty acid amides, fatty amines, fatty alcohols and alkylated phenols.
  • the polyether chains in these compounds are, in general, composed of ethylene oxide units, but also products containing chain links consisting of higher oxalkyl compounds, such as propylene oxide or butylene oxide, or mixtures of the cited alkylene oxides have proved as suitable.
  • polyglycol ethers more especially, polyethylene glycols, having an average molecular weight of from 100 to 2000, preferably of from 200 to 1500, are particularly interesting in view of their use as treating media for the dyestuffs according to the present invention.
  • said substances have to be liquid under the process conditions and they must not decompose at the given treatment temperature.
  • the dyestuff is partly dissolved by the hot solvents, but another portion, differing dependent on the dyestuff used, remains dispersed. However, it cannot be indicated whether the dissolved or the dispersed dyestutf is primarily absorbed by the fibre.
  • the pH value of the dyebath should, as far as possible, be kept below 7, advantageously between 5 and 6.
  • the disperse dyestuffs to be used according to the present process are sufficiently known. In general, they belong to the series of water-insoluble azo, anthraquinone, and phthalocyanine dyestuffs. Examples of the types of such disperse dyestuffs are described in Colour Index, 2nd edition (1956) under the following C.I. numbers: 11100- 11250, 11365-11660, 12700-12795, 26000-26150, 60505- 60755, 61100-61545 and 62015-64505. However, it is possible as well to use in the process organic pigment dyestuffs that are yet unfinished. Since finishing of disperse dyestuffs is just a difiicult measure and, in most cases, a very expensive one, the possibility of direct application of unfinished products is a further substantial advantage of the process of the invention.
  • Still another advantage of new process resides in that the solvents employed may generally provide the function of a detergent, so that in subsequent soaping of the dyeings no separate detergent need be added.
  • EXAMPLE 1 800 g. of a wound-up polyester fibre yarn were placed on a conveyor belt situated in an infrared tunnel preheated to 190 C., said belt moving through the apparatus at a rate of 1.5 m./min. After seconds, the yarn had adopted the corresponding apparatus temperature and reached the position of injection, at which moment the conveyor belt was stopped by means of an optical contact and the dissolved or dispersed dyestuff injected into the yarn package with the aid of an injection needle. Then, the conveyor belt was again put into motion by means of a mechanical contact (released by the retrograde motion of the injection needle support) and the package was allowed to dwell for 30 seconds on the heated conveyor belt.
  • the afore-said used dyeing liquor 200 ml. of which were injected into the package, contained per litre of a reaction product of 1 mol of nonyl phenol with 10 mols of ethylene oxide, 40 g. of the dyestuff (German Pat. No. 1,029,506) of the formula finally dried.
  • a bobbin was obtained wherein about one third of the yarn was dyed a deep blue shade
  • EXAMPLE 2 Using the apparatus described in Example 1, 200 ml. of a dyestuff dispersion having a temperature of C. and containing per litre of a reaction product of 1 mol of stearyl alcohol with 5 mols of ethylene oxide, 30 g. of the dyestuff of the formula in commercial form and quality, were injected into a wound package of yarn of polyester threads pre-heated to 170 C. Subsequently, the bobbin was allowed to dwell for two minutes at the said temperature, whereupon it was treated as described in Example 1. A bobbin was obtained in which about one-third of the yarn was dyed a brilliant red shade.
  • EXAMPLE 3 According to the indications in Example 1, 200 ml. each of the following three dyeing liquors were injected into 800 g. of a wound-up polyester fibre yarn.
  • EXAMPLE 4 Using a dyeing apparatus as in Example 1, 200 ml. of a dyestuif dispersion having a temperature of 210 C. and containing per litre of the solvent specified in Example 3c, g. of the pigment dyestuff (Color Index No. 21110) of the formula CH3 N N Q Q N N CH3 N l I N 1 no on b1 0 When in place of the above dyestuff (German Pat. No. 1,269,587), g. of the dyestutf of formula were used for the dyeing, a bobbin was obtained, about one-third of the yarn of which was dyed a clear blue shade.
  • EXAMPLE 6 In an analogous manner as disclosed in Example 1, 200 ml. of a dyestuff dispersion containing per litre of the solvent indicated in Example 3b, 20 g. of the pigment dyestufi (Color Index No. 51319) of the formula CzHs and having a temperature of 200 C. were injected into 800 g. of a wound-up polyester fibre yarn pre-heated to the same temperature. After the goods had been allowed to dwell for one minute at 200 C. and had been aftertreated, a bobbin was obtained wherein about one-third of the yarn showed a violet shade.
  • EXAMPLE 7 200 ml. of a dyestuff dispersion having a temperature of 190 C. and containing per litre of a polyethylene glycol having a molecular weight of about 200, 20 g. of the dyestulf of the formula CH CH3 were injected, according to the prescription in Example 1, into 800 g. of a wound-up polyester fibre yarn, after the yarn package had been pre-heated to 190 C. After the fabric had been allowed to dwell for 30 seconds at that temperature and, subsequently, after-treated, a bobbin was obtained wherein about one third of the yarn was dyed a deep blue shade.
  • a process for the space-dyeing of a wound-up package of polyester or polyamide fibers or threads by pressure injection of a dyestuif into said package and by fixation of said dyestutf at above ambient temperature the improvement which comprises: pre-heating a woundup package of polyester or polyamide fibers or threads to at least about 160 C.; needle injecting into said woundup package a dyeing liquor at a temperature of about 160 to 230 C., said dyeing liquor consisting essentially of a disperse dyestuff, an organic pigment dyestuif or a combination thereof for said polyester or polyamide fibers or threads dispersed or dissolved in an essentially anhydrous organic solvent selected from the group consisting of an oxalkylation product that is a condensate of lower alkylene oxide and fatty acid, fatty acid amide, fatty amine, fatty alcohol or alkylated phenol, said oxalkylation product having at least two lower alkylene oxide units per units of con
  • a process according to claim 1 wherein said solvent is pentaethylene glycol, hexaethylene glycol, a condensate of nonyl phenol with about 4 to about 20 units of ethylene oxide, or a condensate of a fatty acid, fatty acid amide, fatty amine or fatty alcohol having about 10 to about 18 carbon atoms in the form of a hydrophobic chain with about 2 to about 30 units of ethylene oxide.
