- Appl 695354 Process for dyeing blends of spandex and polyamide fiber materials in which the blended material is first pretreated with Foreign A li ation P i it D t an agent for retarding drawing of the dyestuff on to the polya- J 96 mide fiber portion in the blend; the thus pretreated material is 1 7 Great Bmam "1934/67 then entered into another bath containing the dyestuff and an organic compound, which is a solvent for the dyestuff, or the [52] U.S. Cl.
- Dyes of low hydrophilic character for example those with none or a low degree of sulphonation, partition more satisfactorily by normal dyeing methods but such dyes have other deficiencies.
- disperse dyes have poor wet fastness and some acid and premetallized dyes have poor solubility under low liquor ratio dyeing conditions and generally give stripey dyeings or dyeings of poor solidity on such cloths, especially under jig dyeing conditions.
- an object of this invention to provide a process for the dyeing of blends of fabrics comprising spandex-type and polyamide fibers and by means of hydrophilic dyes, which allows the dyeing of both types of fibers present in the blend in practically uniform depths of shade.
- This object is attained by the process according to the invention which comprises a. pretreating blended fiber material comprising spandextype elastomeric fibers and polyamide fibers with an anionic blocking agent at an elevated temperature capable of retarding the drawing of hydrophilic dyes on to polyamide fibers;
- heating the bath containing the goods, dye and aforesaid organic compound further at a higher temperature, in the range of from 70 C. to the boiling point of the dyebath, in practice between 80 and 100, and optimally between 90 and 95 C., for a period ranging from about 30 minutes to 2 hours, and more preferably for about 1 hour.
- fiber blends are dyed unexpectedly in uniform depths of shade, while, if the dyebath and goods described under (b), supra, are heated in a single heating stage, e.g. at a temperature of 60, or of 90, the polyamide fibers in the blend are dyed in a much deeper shade than the spandex-type fibers.
- spandex-type elastomeric fibers particularly elastomeric polyurethane fibers are used, e.g. those marketed under the tradename of Lycra.
- polyamide fibers nylon fibers, e.g. those of nylon 6 and 6.6 are present in the blended fabrics to be dyed by the process of the invention.
- the said fiber blends to be dyed according to the invention can be in any blending ratio and form desired, e.g. in the form of yarns, fabrics and the like.
- the process according to the invention is particularly suitable for the dyeing of fabrics consisting of elastomeric polyurethane fibers coated with nylon 6 or nylon 6.6 and of fabrics having stretch properties, such as fabrics used for women's foundation garments and swimming costumes.
- the pretreatment with the anionic blocking agent may be carried out by any conventional method.
- the blended fabric may be placed in a bath containing the blocking agent or the fabric may be padded through a concentrated solution of the anionic blocking agent.
- the blocking agent may be an anionic compound which is capable of being exhausted on to nylon occupying amino groups or dye sites, but which is substantially colourless.
- anionic blocking agents which may be used in this process are organic sulphonic acids, such as di-isobutyl naphthalene sulphonate (Irgasol NJ), naphthalene sulphonic acid formaldehyde condensate (lrgasol DA), sulphonated ricinoleic acid (Tinegal BAN) or 4,4'-dichloro-2-(3", 4"- dichlorophenylureido)-di-phenylether-2-sulphonic acid.
- organic sulphonic acids such as di-isobutyl naphthalene sulphonate (Irgasol NJ), naphthalene sulphonic acid formaldehyde condensate (lrgasol DA), sulphonated ricinoleic acid (Tine
- the proportion of anionic blocking agent used may be in the range of 0.1 to 5 percent by weight based on the weight of the fibers and is preferably about 2 percent.
- the pretreatment is most efficiently carried out at a temperature between 70 and C. for a period of 15 to 30 minutes. Longer period of time, however, may conveniently be used.
- the dyeing is commenced preferably in a fresh bath, in the presence of the color, organic compound and, if necessary an acid or acid-salt to adjust the pH of the dye in order to achieve exhaustion on to the fiber.
- the proportion of the dye used in the process may be in a wide range but the quantity used is governed by the shade requirements of the dyeing to be obtained.
- the choice of the organic compound will depend on the particular dye used and the nature of the fibers to be dyed. If the organic compound is insoluble in water, or so slightly soluble that some of it remains undissolved, it is preferably to use an aqueous emulsion of the organic compound. Any emulsifying agent used for forming the aqueous emulsion should not, of course, retard dye absorption. Dyeing can be effected satisfactorily, however, without emulsification of the organic compound if a solvent miscible with both the organic compound and water is present in the dyebath. Examples of suitable organic compounds which may be used in the process of the present invention include higher alkanols having at least four carbon atoms, e.g.
- n-butyl alcohol amyl alcohol and nhexyl alcohol, cyclohexanol, Alphanol (a proprietary mixture of aliphatic alcohols), Nonanol (a proprietary mixture of aliphatic alcohols), Geraniol, Citronellol, Benzyl alcohol, Thymol (3-methyl-6-isopropylphenol), Carvacrol (isopropyl cresol), amyl lactate, dibutyl phthalate, n-butyl acetate, benzaldehyde, acetophenone and toluene. Benzyl alcohol has been found to be particularly useful.
- the amount of organic compound which should be present during the dyeing in an amount of at least about 0.5 percent varies according to the particular organic compound used, the nature of the dyestuff, its concentration in the composition and the temperature to be used. It should be present in sufficient amount to achieve uniform depth of shade on both the spandex-type and the polyamide fibers of the blended fabric. This is usually the case if the organic compound is present in the amount of at least about 0.5 percent calculated on the weight of the dyebath. It may be present up to the maximum amount in water and where benzyl alcohol is used, it is preferably about 2 to 4 percent, calculated on the total weight of the dyebath.
- the dye liquor can contain further auxiliaries usual in the textile industry, particularly acids or acid salts, such as organic acids or their salts and also inorganic acids or their salts. Examples of these compounds are acetic acid, ammonium acetate, sulphuric acid, ammonium sulphate and ethyl lactate.
- the acid or acid-salt used may be in a quantity conventionally used in the dyeing of nylon but is preferably a solution having a concentration in the range of 0.01 to 1 percent.
- the dyestuffs draw so well on e.g. the polyurethane part of spandex-type fibers in the blended material that well penetrated dyeings of uniform depth of shade on both the spandex-type and the polyamide fibers are obtained.
- the blended fabric is then transferred to a fresh bath con taining 2 g of the dyestuff of the formula (Acid Blue 113, Color Index No. 26360),
- a fabric is obtained in which the polyurethane and polyamide fibers are dyed in a blue shade of uniform depth.
- the weight ratio of Lycra to nylon 6.6 fibers in the blended. fabric used in Example 1 and all subsequent examples is 1:1. Similar results are obtained in which this ratio is 3:1, 3:2, 1:2 or 1:3, or in which the nylon 6.6 fibers are replaced by nylon 6 fibers.
- EXAMPLE 2 200 g. of fabric consisting of a blend of Lycra and nylon 6.6 fibers are pretreated for 30 minutes at 9095 C. with 4 g. of di-isobutyl naphthalene sulfonate in the presence of 0.5 ml of 40 percent acetic acid in 1,000 ml. ofwater.
- the blended fabric is then dyed in a fresh bath containing 4 g. of acid navy blue dye, the major portion of which consists of Acid Blue 1 13, 0.5 ml of 40 percent acetic acid, and 40 ml. of benzyl alcohol in 1,000 ml. of water for 20 minutes at 40 C., and 40 minutes at 50 C.
- the temperature of the dye bath is then raised to 90-95 C. and maintained at this level for 1 hour.
- a fabric dyed in a deep blue shade of uniform depth is obtained.
- a fabric of blue shade and similar substantially uniform depth is obtained by repeating Example 2, but using therein 4 g. of the dyestuff of the formula EXAMPLE 3 200 g. of-fabric consisting of a blend of Lycra and nylon 6.6 fibers are pretreated for 30 minutes at -95 C. with 4 g. of di-isobutyl naphthalene sulfonate in the presence of 0.5 ml. of 40 percent acetic acid in L000 ml. of water.
- the blended fabric is then dyed in a fresh bath containing 10 g. of the dye which is a mixture in a weight ratio of about 1:1 of the 1:1 and 1:2 chromium complexes of the dye-stuff of the formula OH HO (Acid Black 52, Color Index No. 15711), 0.25 ml of 40 percent acetic acid and 40 ml. of benzyl alcohol in 1,000 ml. of water for 20 minutes at 40 C., and 40 minutes at 50 C.
- the temperature of the dye bath is subsequently raised to 9095 C. and maintained for 1 hour.
- a blended fabric dyed black in uniform depth of shade is obtained.
- the blended fabric is then dyed in a fresh bath containing 3 g. of the same dyestuff as is employed in Example 1, 0.5 ml. of 40 percent acetic acid, and 40 ml. of benzyl alcohol in 1,000 ml. of water for 1 hour at 50 C.

- EXAMPLE 5 200 g. of fabric consisting of a blend of Lycra and nylon 6.6 fibers are pretreated for 30 minutes at 9095 C, with l0 g. of a condensation product from naphthalene-Z-sulfonic acid and formaldehyde in the presence of 0.5 ml of 40 percent acetic acid in 1,000 m1 of water.
- the fabric is then dyed in a fresh bath containing 3 g. of a dyestuff used in Example 1, 0.5 ml of 40 percent acetic acid, and 40 ml. of benzyl alcohol in 1,000 ml. of water for one hour at 50 C.
- the temperature of the dye bath is subsequently raised to 90-95 C. and maintained for 1 hour.
- a fabric dyed in blue shade is obtained in which the polyurethane and the nylon fibers are dyed with the same depth of shade.
- a fabric in which the polyurethane and the nylon fibers are both dyed orange in practically the same depth of shade is obtained by repeating Example 5, but using as dye therein 3 g. of the dyestuff ofthe formula SOJH By repeating the procedure described in the above Example but using instead of 40 ml. only 20 ml. of benzyl alcohol, an equally uniform orange dyeing on said blended fabric is obtained.
- EXAMPLE 6 200 g. of a fabric consisting of a blend of Lycra and nylon 6.6 fibers are pretreated for 30 minutes at 9095 C. with 2 g of sulfonated ricinoleic acid in the presence of 0.5 ml. of 40 percent acetic acid in 1,000 ml. ofwater.
- the pretreated fabric is then dyed in a fresh bath containing 3 g. of the dyestuff used in Example 1 in the presence of 0.5 ml of 40 percent acetic acid and 40 ml. of benzyl alcohol in 1,000 ml. of water for 1 hour at 50 C.
