Definitions
- the products of polymerisation or copolymerisation of acrylonitrile or vinylidene cyanide may be in various forms such as, for example, fibres, threads, coarse fibres, fabrics or sheets. In view of this, they are on occasion treated with other products e.g. productsresulting from a polymerisation, or mineral or organic products intended to modify the physical properties of the substance or its physical appearance.
- Certain copolymers may contain products whose object is either toloosen the internal structure of 'the macromolecular acrylic chains or to provide chemical functions: assisting in the fixation of the dyes, for example basic functions able to combine with the sulphonic or 'carboxylic gronps lof the solQuble orpseudo-soluble dyes.
- the products considered capable of being dyed may be mentioned theE fibres-or 2,937,067, Patented May 17,19 0
- the colouration can be obtained by dyeing or printing.
- the dyeing can be carried out by known methods, either by circulating the bath, the material being stationary, or bypassing the material through the bath (vats, jigger, foulard) ,'or by employing apparatus which combines both movements.
- vats, jigger, foulard a material which is stationary, or bypassing the material through the bath (vats, jigger, foulard) ,'or by employing apparatus which combines both movements.
- a temperature above 100. 0. one can operate either .in an'aqueous bath open to the airwhose boiling point has been raised by the addition of soluble salts, or inan autoclave.
- the foulardgthe fabric passesthrough the bath for some seconds and is then squeezed out between the rollers .of the. apparatus; thefixation of the dye is then carried out, with or without intermediate drying, by thermal treatment above 80 C.: the desired temperature is obtained by circulation of hot air, infra-red radiation,
- the chromium complexes called 1:1 that is, possessing one atom of. metal attached to one molecule of dye. These dyes are generally used for dyeing wool in a strongly acid bath or for dyeing polyamide fibres.
- vanadium or manganese vanadium or manganese. It-does not matter if oxidis ing salts such as dichromates, chromates, or perman-y ganates are used which destroy the hydroxylamine.
- the complex can also-be previously prepared before the dye ing,.-by the action of the dye on the metal salt, isolation of the complex and use immediately for colouration; in
- the dye baths or the printing pastes include the following elements: 7
- the dye, the, hydroxylamine or one of its salts such as the neutral sulphate, the acid sulphate, the hydrochloride, or the phosphate, and possibly the following products: soluble metal salts when the dye is not itself a metal complex, acids or alkalis intended to produce the pH conditions which are most satisfactory for the substance to be dyed, wetting and dispersing agents of anionic or non-ionic type intended to improve the wettability of the material, the uniformity of the dyeing and the dispersion of incompletely soluble dyes, swelling agents such as orthoor para-phenyl phenol, resorcinol, dimethylformamide,.soluble lithium salts, calcium thiocyanate, intended to facilitate the penetration of the dye into polymers which are difiicult to penetrate.
- soluble metal salts when the dye is not itself a metal complex
- acids or alkalis intended to produce the pH conditions which are most satisfactory for the substance to be dyed
- the colouration is effected by one of the previously mentioned processes of dyeing or printing at a temperature above 100 C. At l20l30 C. the results are always excellent and the bath is almost completely exhausted.
- the optimum temperature for the colouration is governed by the characteristics of the material to be coloured, which characteristics depend to a considerable extent on the method of manufacture of the latter.
- hydroxylamine or salt thereof and the amounts of metal salts vary according tothe depth of the shade and the bath ratio; in practice, however, they range from 0.5% to 10% based on the weight of the material to be coloured.
- the present process allows not only dyes of the same group to be used in combination but also dyes of difierent groups, and even metalliferous dyes with metallisable dyes in the presence of metal salts. Dyes which are soluble and insoluble in an aqueous medium can also be used in combination. Finally, two or more salts of the same metal or different metals can be added when dyeing with metallisable dyes.
- a modification of the process of this invention consists in adding to the dyebath or to the printing paste, not hydroxylamine or one of its salts, but products capable of giving them under the conditions of application.
- a nitrite, such as sodium nitrite, and sodium bisulphite may be used and an acid, such as sulphuric acid, added before the colouration.
- the action of the acid on the bisulphite liberates sulphur dioxide, which reduces the nitrite, or nitrous acid occasionally formed, to hydroxylamine.
- the conditions for the colouration are not the optimum conditions for the preparation of hydroxylamine, so that the tinctorial yields are less than when hydroxylamine or one of its salts is added directly to the'bath.
- Another variation of the process consists in adding hydroxylamine sulphate to the bath and liberating the base by the addition of sodium carbonate or a strong base, e.g. caustic soda or caustic potash.
- the shades obtained are very varied and cover all those required in dyeing and printing; they display remarkable fastness both to light and to wet.or other treatments.
- Example 11 one operates according to the process described in the first paragraph of Example 1, but instead of the dye mentioned in the latter exam-pie, one of those in Table 11 below is used.
- the latter dyes denoted by the name under which they are known on the market, are 2:1 complexes of chromium or cobalt.
- I 1 yellow Green Sirius Light FFGLU/ EXAMPLE '3 In this example one operates as indicated in Example 1, but replacing the complex used by the copper complex of the dye obtained by coupling the tetrazo derivative of dianisidine with one molecule of l-hydroxy-naphthalene- 3:8-disulphonic acid and one molecule of 6-phenylamino- 1-hydroxy-3-naphthalenesulphonic acid. A navy .blue colour is obtained.
- Table III below summariseszsome examples of colours obtained with the metalliferous polyazo dyes according to the same process; these dyes are denoted by the commercial names under which they are known on the market.
- Ruby Ohlorantine Light ELL ruby It is also possible to operate as has just been indicated by adding to the dye bath 0.8 to 1 part of sodium carbonate in order to liberate the hydroxylamine. According to this process there is obtainedwith the Brown Diazole Light BRN a yellowish brown colour on -a polyacrylonitrile fibre of the Orlon type.

NEW PROCESS FOR THE COLORATION F SYN-' THETIC MATERIALS .AND THE INDUSTRIAL.
j PRODUCTS RESULTING THEREFROM;
Joseph Khachoyan, Chantilly, and Jean-Paul Nieder nets resulting therefrom. i The colouration by dyeing or by printing of synthetic fibres based on polyacrylonitrile gives-riseto difliculties.
At present, some particular members of f'different classes of dyes give results which can be made use of in industry namely; plastosoluble dyes, vat dyes, basic dyes, in-
soluble azo dyes formed on the fibres and acid dyes ap,-"
plied according to the cuprous ion process. Their application can be effected at 100C. or ata higher terne perature; application above IOO C. results in an irnprovement of the penetration, uniformity, speed of dyeing,
and sometimes the yield of these dyes. Nevertheless, it
has not been possibleto extend the use of this method and'therefore to enlarge the range of dyes which can be employed to colour products based on polyacrylonitrile Another solution has been proposed fo'r this purpose.
It consists in making copolymerscontaining, besides acrylonitrile, products capable of facilitating 'the dyeing or printing by-loosening'the internal structure of the fibre or providing chemical functions on which certain dyes can become fixed.
Finally, in French Patent No. l,O94,620 there is described a process for dyeing fibres based on polyacrylonitrile which COHSiStS'iH using the copper complexes of o:o-dihydr0xy monoazo dyescontaining only one sul-' phonic group, in the presence ofhydroxylamine sulphate. It has now been found that the products 'of'polymerisa tion or copolymerisation; of acrylonitrile or vinylidene' cyanide can be dyed in strong shades by means of dyes which are soluble or insoluble in water, other than those of the above-mentioned French Patent, by operating without copper salt in the presence of hydroxylamine in the free state or in the form of a'salt thereof, at a temperature above 100 C. The tinctorial yield is, in-general, superior to that which is obtained by first treating the fibre with hydroxylarnine (for example, according to the process of US. Patent No. 2,792,276) or by carrying out the dyeing in the presence of hydroxylamine at a temperature below 100 C.
. The products of polymerisation or copolymerisation of acrylonitrile or vinylidene cyanide may be in various forms such as, for example, fibres, threads, coarse fibres, fabrics or sheets. In view of this, they are on occasion treated with other products e.g. productsresulting from a polymerisation, or mineral or organic products intended to modify the physical properties of the substance or its physical appearance. Certain copolymers may contain products whose object is either toloosen the internal structure of 'the macromolecular acrylic chains or to provide chemical functions: assisting in the fixation of the dyes, for example basic functions able to combine with the sulphonic or 'carboxylic gronps lof the solQuble orpseudo-soluble dyes. Among the products considered capable of being dyed may be mentioned theE fibres-or 2,937,067, Patented May 17,19 0

The colouration can be obtained by dyeing or printing. The dyeing can be carried out by known methods, either by circulating the bath, the material being stationary, or bypassing the material through the bath (vats, jigger, foulard) ,'or by employing apparatus which combines both movements. In order to reach a temperature above 100. 0., one can operate either .in an'aqueous bath open to the airwhose boiling point has been raised by the addition of soluble salts, or inan autoclave. When working on the foulardgthe fabric passesthrough the bath for some seconds and is then squeezed out between the rollers .of the. apparatus; thefixation of the dye is then carried out, with or without intermediate drying, by thermal treatment above 80 C.: the desired temperature is obtained by circulation of hot air, infra-red radiation,
contact with a heated metal, by steaming by means of steam at normal pressure or under pressure, or by treatment at a temperature above 80 C.-in an aqueous bath open to the airior under, pressure, or by any other suitable means. Printing of'thepolymers and copolymers inquestion can be carried out by means of the usualappa-ratusby.-the application of a paste containing a thickener; thefixation is effected by. one of the methods indicated above for foula'rded fabrics.
The num'ber of dyes, soluble, pseudo soluble or in soluble-in an aqueous medium, which can be applied according to the present process is large. By way of example, there may be mentioned: 1
(1) The acid dyes and the direct dyes. t
(2) The chromium complexes, called 1:1 that is, possessing one atom of. metal attached to one molecule of dye. These dyes are generally used for dyeing wool in a strongly acid bath or for dyeing polyamide fibres. (3) Metalliferous complexes, chiefly of chromium or cobalt, called 2:1, that is, possessing one atom of chromiprocess, the chromium dyes are :applied in the presence -of soluble metal salts, of chromium, iron, nickel, cobalt,
vanadium or manganese. It-does not matter if oxidis ing salts such as dichromates, chromates, or perman-y ganates are used which destroy the hydroxylamine. The complex can also-be previously prepared before the dye ing,.-by the action of the dye on the metal salt, isolation of the complex and use immediately for colouration; in
this case, it is not necessary to add a metal salt to the bathor the paste.
(-7;) .;The direct metallisable ,dyes; according to the present process these-direct dyes are appliedin the presence of soluble metal salts, of chromium, iron,'vanadiurn, nickel, cobalt, tin,-.-alumini um or manganese. It does not matter if oxidising salts which destroy the hydroxylamineareiused; The complexcan also bepi'eviviously'Ii: re1'izi1ied, beforethe' dyeing, "by the action of-the non-metallisable The metal 3 dye on the metal salt, isolation and use immediately for colouration; in this case, it is not necessary to add a metal salt to the bathor the paste.
(8) The leuco esters of vat dyes.
The dye baths or the printing pastes include the following elements: 7
The dye, the, hydroxylamine or one of its salts, such as the neutral sulphate, the acid sulphate, the hydrochloride, or the phosphate, and possibly the following products: soluble metal salts when the dye is not itself a metal complex, acids or alkalis intended to produce the pH conditions which are most satisfactory for the substance to be dyed, wetting and dispersing agents of anionic or non-ionic type intended to improve the wettability of the material, the uniformity of the dyeing and the dispersion of incompletely soluble dyes, swelling agents such as orthoor para-phenyl phenol, resorcinol, dimethylformamide,.soluble lithium salts, calcium thiocyanate, intended to facilitate the penetration of the dye into polymers which are difiicult to penetrate.
The colouration is effected by one of the previously mentioned processes of dyeing or printing at a temperature above 100 C. At l20l30 C. the results are always excellent and the bath is almost completely exhausted. The optimum temperature for the colouration is governed by the characteristics of the material to be coloured, which characteristics depend to a considerable extent on the method of manufacture of the latter. At the end of the dyeing or printing, it is expedient to subject the material to hot soaping, using soap or an anionic or non-ionic product, so as 'to purify the shade and remove particles of dye badly fixed on the surface.
The amounts of hydroxylamine or salt thereof and the amounts of metal salts vary according tothe depth of the shade and the bath ratio; in practice, however, they range from 0.5% to 10% based on the weight of the material to be coloured.
The present process allows not only dyes of the same group to be used in combination but also dyes of difierent groups, and even metalliferous dyes with metallisable dyes in the presence of metal salts. Dyes which are soluble and insoluble in an aqueous medium can also be used in combination. Finally, two or more salts of the same metal or different metals can be added when dyeing with metallisable dyes.
A modification of the process of this invention consists in adding to the dyebath or to the printing paste, not hydroxylamine or one of its salts, but products capable of giving them under the conditions of application. A nitrite, such as sodium nitrite, and sodium bisulphite may be used and an acid, such as sulphuric acid, added before the colouration. The action of the acid on the bisulphite liberates sulphur dioxide, which reduces the nitrite, or nitrous acid occasionally formed, to hydroxylamine. Nevertheless, the conditions for the colouration are not the optimum conditions for the preparation of hydroxylamine, so that the tinctorial yields are less than when hydroxylamine or one of its salts is added directly to the'bath.
Another variation of the process consists in adding hydroxylamine sulphate to the bath and liberating the base by the addition of sodium carbonate or a strong base, e.g. caustic soda or caustic potash.
The shades obtained are very varied and cover all those required in dyeing and printing; they display remarkable fastness both to light and to wet.or other treatments.
The examples which follow, which are not restrictive and in which the parts indicated are parts by weight, describe processes of colouration in accordance with the present invention.
