The printing bath or printing paste contains as ingredients a compound of the following forwherein X is a halogen atom and nucleus A may have a halogen atom, a lower alkyl or lower alkoxy group as a substituent, together with inorganic alkaline substances, the pH being kept at 8 or more.
The present inventors have found that a deep black colored print with desired fastness can be readily obtained by pad-dyeing or printing the textile fabrics with the above mentioned compound and an inorganic alkali. The step may be effected at any stage of the process.
A black colored print on hydrophobic substances is well known. To obtain this effect, the dyeing is performed using aniline orthotoluidine, 4-amino-diphenylamine and the like. Japanese patent publication Nos. 10,382/63 and 19,639/63 disclose a two bath dyeing process wherein dyeing is carried out with the use of the compound of the above-mentioned general formula after hydrophobic fibers are treated with aromatic compounds having two amino groups or azomethine compounds obtained by condensation of aromatic amine and aromatic aldehyde. Another method for obtaining a black colored print on polypropylene fibers is described in Example 1 of Japanese patent publication No. 24,658/64. The method is that the compound of the general formula,
wherein X and A have the same meanings as mentioned above, is used together with an aromatic amine. In this case, however, the printing paste has poor stability since the two components react readily with on another to produce a black color, with consequent problems such as ice poor dye-fixing, particularly where there is the usual intermediate drying step. In the usual printing method, the printed woven fabrics are usually subjected to drying and then to steaming in order to fix the dye. However, no matter how rapidly the printing is performed, the blacking reaction proceeds during the drying process of the dyed Woven fabric with so-called lake formation. In such lake formation, the dye forms large molecules which do not fix onto polypropylene fibers even in the subsequent steaming process. Even if it fixed onto said fibers, the reproductibility is not good. The same defect is seen when benzene, naphthalene or quinoline derivative having one or more hydroxyl radical besides the above-mentioned aromatic amine are used. Stability of printing paste or storage of dried cloth are requested in pattern print.
The present inventors have succeeded in providing a pad-dyeing or printing method of notable characteristics which comprises conducting the dyeing or printing with the use of a dyeing bath or a printing paste comprising inorganic alkali and the compound of the general formula,
wherein X and A have the same meanings as mentioned above, keeping pH at 8 or more. The bath or paste may further have aromatic amines and/ or compounds selected from benzene, naphthalene and quinoline derivatives. As to the benzene and naphthalene and quinoline derivatives. As to the benezene and naphthalene, at least one of hydrogen atoms capable of being substituted should be replaced by hydroxyl group and the other remaining hydrogen atoms may be substituted by the other groups than sulphonic group. The present paste or bath is completely stable, and furthermore even if a dried cloth printed with this paste is allowed to stand for a long period of time, polycondensation does not proceed instantaneously and black coloring reaction does not take place. Polyolefin fibers are dyed in black only when they are subsequently steamed or dry-heated.
Color shade obtained by the method of this invention is illustrated by the revised Munsell remotation as follows:
Hue
According to this invention, such neutral black color as mentioned above can always be obtained with good reproducibility.
Quinonedihalimine derivative represented by the general formula, which can be used in the present invention, includes, for example, 1,4-quinone-dichlorimine, 1,4- quinone-dibromimine or their 2-chloro, 2-bromo, 2-methyl, Z-ethyl, Z-methoxy, Z-ethoxy, 2,6-dichloro, 2,5-di. chloro,2,5-dimethyl, 2,5-dimethoxy or 2,5-diethoxy substituted compound alone or a mixture thereof. Inorganic alkaline agent includes hydroxides of alkali metal or alkaline earth metal, their basic salts or a mixture thereof. For example, there are sodium carbonate, potassium car.- bonate, sodium hydroxide, potassium hydroxide, sodium bicarbonate, sodium tertiary phosphate, sodium silicate, quicklime and the like. The amount of these alkaline agents to be used varies according to the kind of alkaline, however, in the case of potassium carbonate, for example, about 120% by Weight, preferably about 5% by weight is added to a padding bath or a printing paste.
The aromatic amines include aniline, 0- or m-toluidine, or m-xylidine, 2,3-dimethylaniline, 0- or m-chloroaniline, por m-aminophenol, 4-aminodiphenylamine or the like.
Benzene and naphthalene should have at least one bydroxyl group but may further have the other group than sulfonic acid group. Such benzene and napthalene or quinoline derivatives include phenol, mor p-cresol, 0- or p-butylphenol, oor p-octylphenol, oor p-cyclohexylphenol, 2,4-xylenol, 3,5-xylenol, 2-butyl-4-cresol, 4-amino- Z-cresol, 6-butyl-3-cresol, op-phenylphenol,'o-, mor pchlorophenol, o-, mor n-nitrolphenol, 0- or p-hydroxy benzoic acid or methyl, ethyl or butyl ester thereof, N- dimethyl or diethyl-m-aminophenol, 0-, mor p-acetylaminophenol, m-hydroxydiphenylamine, 3 -hydroxy-2- methyldiphenylamine, catechol, resorcinol or hydroquinone or mono-methyl or mono-ethyl ether, pyrogallol, a-naphthol, B-napthol, 4-methyl-u-napthol, 4-methoxy-anaphthol, 4,8 dimethoxy-a-naphthol, 5,8 dlChlOl'O-Otnaphthol, 1,5 or 2,3-dihydroxynaphthalene, 04- or ,G-hydroxymaphthenic acid, or methyl or ethyl ester thereof, 5- hydroxynaphthenic acid anilide or alkyl-, alkoxyand/or halogen-substituted compound thereof, 8-hydroxyquinoline, 2,4-dihydroxyquinoline, N-methylor N-butyl- 2,4-dihydroxyquinoline or the like. These can be used in the form of sodium or potassium phenolate, etc., too. They are used either alone or in the form of a mixture.
The present process will be illustrated hereinunder referring to printing. To 10 g. of p-dichloroquinonediimine powder (effective ingredient: 84%), a small amount of water is added and said power is sufiiciently kneaded. Afterwards, a suitable amount of a viscosity promoting agent such as British gum is added thereto and 5 g. of potassium carbonate powder as the inorganic alkaline agent is further added to prepare 100 g. of a uniform and viscous paste. The paste thus obtained is printed onto polypropylene woven fabric and dried at about 50 C. Then, it is subjected to steaming for about minutes, washing with water and soaping and finished to obtain a print of deep black color. Furthermore, a printing paste prepared by adding a suitable amount of the aromatic amines or phenol derivatives to the above-mentioned printing paste is printed onto polypropylene woven fabric and dried at about 50 C. Then, it is subjected to steaming and sub jected to water washing and soaping according to the usual method to obtain a print cloth of black color.
The amount of p-dichloroquinonediimine to be used in accordance with the method of the present invention can be optionally decided, preferably about 10%, by weight based on the weight of the paste, judging from the condition of paste-status of the printing paste or color value.
The amount of the inorganic alkaline to be added varies according to the kind thereof. For example, in case of potassium carbonate, its effective amount is 110% by weight based on the weight of the paste, preferably 5%. Furthermore, when alkaline is of little amount, for example, less than 2% by weight, the printing paste becomes to give no dye-fixing onto woven fabric.
Stability of printing paste greatly varies, particularly according to the kind of the alkaline to be added. From the point of the storage stability, sodium carbonate, sodium phosphite, sodium cyanide, sodium silicate, potassium carbonate, sodium bicarbonate are preferred, and they do not damage the paste for as long as one week.
When the aromatic amines or phenols are used, the most preferred ratio of p-dichloroquinonediimine to aniline, for example, is about 1:1 by weight ration. The ratio naturally varies depending on the kinds of the amines, phenols and the other component, quinonedihaloimide. Although color shade varies according to the kind of the above-mentioned aromatic amines or phenols or the material to be dyed, for example, on polyolefin fibers, aromatic amines usually give reddish color shade, and phenols bluish color shade.
The printed cloth with, for example, p-dichloroquinonediimine tends to stain white ground due to sublimation of the dye fixed on said cloth in steaming. Reduction cleaning with hydrosulfite and sodium hydroxide is effective to remove the stains and a printed cloth having favorable white ground can be obtained Moreover, by the pretreatment of the fabric with organic acid such as tartaric acid, formic acid, citric acid, etc. and inorganic acid such as sulfuric acid, phosphoric acid, etc., drying and after-treatment such as steaming, etc., the effect to improve the white ground of printed cloth can be sufliciently displayed even when the amount of acids used is as little as 5-20 g./1. or so.
Since the present method is carried out at alkaline side, the viscosity promoters used in the present invention are natural or synthetic starch agent such as alkaline resisting tragacanth gum, British gum, crystal gum, Meypro gum (locust bean gum), starch, etc. These can basically be applied singly or in admixture, as well as alkali resisting water-in-oil type and oil-in-water type emulsions containing the above-mention starch agents.
On the other hand, the amount of inorganic alkaline to be added and the structure of fabric influence the steaming as dye-fixing, but generally a period of from 5 to 30 minutes is sufficient. If required, the steaming at a practically high temperature below the softening point of fiber enables sufficient dye diffusion into the interior of fibers, and deeper black color can be obtained. Furthermore, the dry heat treatment and curing or baking at a temperature of l00l40 C., which is below the softening point of fiber, for ll0 minutes are carried out and then washed with water and soaped to obtain 'black color on the objective goods.
Still more, by dry heat fixing, a carrier or swelling agent or hygrometric agent usually used for the dyeing of synthetic fibers, may be added to the prescription of the printing paste, by which a deep and fast black color can be obtained. As compounds therefor, there are benzonitrile, trichlorobenzene, urea, thiourea, sodium chloride, glycerine, triethanolamine, diethyleneglycol, etc., which can be used singly or in a mixture comprising several of the above.
Next, the pad-dyeing by the present invention can be also carried out in a similar manner to that of printing to dye the objects black.
That is, p-dichloroquinonediimine powder (effective ingredient: 84%) and a dispersing agent, for example, a small amount of formalin condensation product of an anionic alkylnaphthalenesulfonic acid are sufficiently kneaded, and dispersed in the padding bath aqueous solution and a suitable amount of potassium carbonate, for example, as inorganic alkaline is added thereo. The polypropylene fabric is immersed therein, and then subjected to steaming or dry heat treatment at a temperature below the softening point of the fibers to obtain good black color. When polypropylene fabric is immersed in a uniform padding solution in a padding bath containing aromatic amines such as aniline, etc. or the above-mentioned phenols, and after removing the solution therefrom, subjected to the same treatments as mentioned above a deep black color is obtained on the fabric.
Although the amount of p-dichloroquinonediimine powder (effective ingredient: 84%) to be used in the paddyeing of the present invention varies according to the mangle pick up rate, the preferred amount is 15-20% by weight based on the weight of the dyeing bath in case of the mangle pick up rate of Furthermore, the dispersing agent is not always necessary, but is effectively used in the dispersion of p-dichloroquinonediimine and the stabilization of dyeing bath and carrying out a uniform dyeing. For this object, for example, a formalin condensation product of alkylnaphthalenesulfonic acid can be used.
The amount of inorganic alkaline to be used varies according to the amount of p-dichloroquinonediimine used. For example, potassium carbonate in an amount of 2-20% by weight, preferably about 5% by weight or so based on the weight of a dyeing bath, is effective for that object.
Furthermore, the ratio of the above-mentioned aromatic amines and phenol derivatives to quinonedihalirnide is not definitely fixed since it depends on the two components or the desired color shade and depth of the dyed objects. For example, in the combination of p-dichloroquinonediimine and aniline, the most favorable black color can be attained, when the ratio of the two components is close to 1:1 by weight ratio.
Moreover, the present method can be applied to the yarn by an adsorption printing method to provide a black color to polypropylene yarn. However, it is not commercially advantageous, because 2025% by weight of p-dichloroquinonediimine is required to the yarn weight which is quite large.
In the present invention, the dyeing mechanism and the structure of the dye fixed on the dyed cloth are quite complicated and obscure, because in the present method the reactants proceed through an oxidation or condensation of dye. For example, it is assumed that the dehydrochloric acid condensation of p-dichloroquinonediimine takes place by the action of inorganic alkaline to form linear or reticulated polybenzoquinone derivative on the fibers.
Still more, regarding the mechanism of dye fixing, it is considered that the low polycondensation product of p-dichloroquinonediimine itself or the low polycondensation product of p-dihaloquinonediimine and decomposition product thereof, or the low polycondensation product of pdihaloquinonediimine and phenol reacts with itself to form a higher polycondensation product on the fibers and thus give fast dye fixing to the fabric.
The dyeing of present method can be applied to fibers including the synthetic fibers such as polyolefin, polyester, polyamide, polyacrylonitrile, polyvinyl chloride, etc. as mentioned above and the semi-synthetic fibers such as acetate and triacetate etc. Particularly, according to the present method, a good black color can be given to polyolefin fibers.
