Definitions
- This invention relates to the art of printing textiles and more particularly relates to an improved textile printing paste containing an insoluble color pigment, to the method of applying the same to a fabric and to the improved printed fabric obtained.
- the water-dn-oll type of cellulose ether emulsion which has been found to be useful in carrying out this invention will contain a water-insoluble cellulose ether, as, for example, ethyl cellulose, propyl cellulose, butyl cellulose, benzyl cellulose, mixed ethyl benzyl cellulose, mixed ethyl 1 butyl cellulose, etc.
- a water-in-oil type of mulsuch colors from a paste containing the coloring agent in a soluble form and developing the insoluble coloron the fabric by suitable after-treatment.
- Such printing pastes have contained as carriers or thickeners such materials as starch and gum tragacanth. After the paste has been applied to the fabric and the color has.beco me fixed or developed on the fabric by some suitable treatment, the fabric is subjected to a washing treatment to remove the starch or gum carrier.
- the color developing or fixing op ration is a very delicate operation subject to a wide variability in the final result; Insumcient developing or over developing are common reasons for rejection of the printed goods. Also, many delicate fabrics do not satisfactorily withstand the rather severe washing treatment necessary to remove the starch or'gum carrier and thus give printed fabrics of weakened strength.
- the insoluble color pigment isin its fully devolped state, no treatment on .the fabric is sion of a cellulose ether is particularly useful in this invention because of the high viscosity which such emulsions possess with very low solids content.
- water-in-oil type of cellulose ether emulsion utilized in this invention may be prepared by first emulsifying a water-immiscible solvent solution of the cellulose ether, carrying out the emulsiflcation in water with the aid of a suitable emulsifying agent. If desired, a plasticizer for the cellulose ether or a suitable synthetic resin, or both. may be included in the solvent solution of the cellulose ether. The oil-in-water type of emulsion formed in this manner may then be reversed to a water-in-oil type of emulsion. In this manner, the cellulose ether solution becomes the continu-.
- a waterin-oil emulsion of the cellulose ether may be prepared directly without-the intermediate preparation of the oil-in-water type of emulsion.
- plasticizers for the cellulose ether a solid or a liquid plasticizer may be used. Suitable plasticizers are hydrogenated methyl abietate, hydrogenated ethyl abietate, triphenyl phosphate, tributyl phosphate, methylphthalylmethyl glycollate, ethylphthalylethyl glycollate, etc.
- a resin which is compatible with the cellulose ether, is resistant'to alkalies and exerts a softening action on the cellulose ether may be used.
- softening action I mean a lowering of the melting point of the cellulose ether and not necessarily a plasticizing of the cellulose ether-- in the strict sense of the term.
- rosin modified alkyd resins such as rosin modified or hydrogenated rosin modified terpene-maleio"anhydride resins, rosin modified maleate resins, drying oil modified terpene-maleic anhydride resins, polymerized hydrocarbon resins,
- x such x as polymerized napthalene, polymerized coumaroneindene, or hydrogenated forms thereof, 100% phenolic resins, polyhydric alcohol esters of hydrogenated rosin, as well as other types having the above defined properties, may be used with w the cellulose ether.
- emulsifying agents for preparing the emulsion of the cellulose ether with or without'a plas- 55 ticizer and with or without asuitable resin may employ, for example, the alkali metal salts of the higher aliphatic half ester sulfates, as sodium lauryl sulfate, sodium stearyl sulfate, etc; sulfonated oils, as sulfonated castor oil, sulfonated olive soil, etc; soaps, as sodium stearate, potassium oleate, sodium oleate, etc; alkali metal salts of alkyl naphthalene sulfonic acids, as sodium butyl naphthalene sulfonate, sodium isopropyl naphthalene sulfonate, etc.
- the alkali metal salts of the higher aliphatic half ester sulfates as sodium lauryl sulfate, sodium stearyl sulf
- cellulose ether together with the plasticizer and the resin, if either or both are employed, will preferably be dissolved in a suitable water-immiscible solvent mixture before emulsification and the solvent solution emulsified in water by means of the emulsifying agent.
- suitable solvent mixtures may include solvents such as, forexample, light aromatic hydrocarbons, as,
- Stoddard solvent Solvesso No. 2, Solvesso No. 3, etc.
- butanol pine oil, etc.
- Stoddard solvent Solvesso No. 2, and Solvesso No. 3 are meant the petroleum hydrocarbon solvents known in the industry by those names. They may be generally characterized as follows:
- the oil-in-water type of emulsion obtained according to the above description may be reversed so as to form a water-in-oil type of emulsion by addition of a suitable reversing agent as, for example, aluminum stearate, acetic acid, a mixture of pine oil and acetic acid, or an alkali, as potassium or sodium hydroxide, or by any other suitable means. If it is desirable to. prepare a water-inoil type emulsion directly, this may be done, for example, by adding one of the above reversing agents to the solvent solution of the cellulose ether and emulsifying in water with an emulsifying agent.
- a suitable reversing agent as, for example, aluminum stearate, acetic acid, a mixture of pine oil and acetic acid, or an alkali, as potassium or sodium hydroxide, or by any other suitable means.
- a water-in-oil type emulsion may also be prepared directly by stirring water and a suitable solvent into a water-immiscible solvent solution of a water-insoluble cellulose ether containing an insoluble pigment in dispersed form, then homogenizing the resulting water-in-oil type emulsion in a suitable colloid mill or homogenizer. If desired, the pigment may be first dispersed in the water and the emulsion prepared as above.
- the insoluble color pigments which constitute an essential component of the printing pastes described in accordance with this invention may be either the inorganic or the organic coloring materials which are insoluble in either water or oil and are commonly used inprinting pastes.
- the organic pigments are those which consist either wholly or in part of dyestuffs which have been rendered insoluble in water and oil. These include those organic pigments which are made by precipitation on a suitable base. These also include the dyes which have been precipitated or rendered water-insoluble by various precipitating means such as barium chloride, lead acetate, tartaric acid, aluminum hydrate, etc., as well as the insoluble lakes and azo and diazo colors.
- the printing pastes prepared and utilized in accordance with this invention may be prepared by mixing the insoluble color pigment such as described above into the water-in-oil emulsion of a water-insoluble cellulose ether to provide the improved printing paste.
- the body and thickness of the printing paste may be varied as desired by variation of the ingredients of the waterin-oil emulsion of the cellulose ether and by the amount of dissolved solids in the emulsion as well as by theamount of the solvent and by the amount of the color pigment added, and mixing the insoluble color pigment with the cellulose ether emulsion.

G'GIaims.
This invention relates to the art of printing textiles and more particularly relates to an improved textile printing paste containing an insoluble color pigment, to the method of applying the same to a fabric and to the improved printed fabric obtained.
It has heretofore been the practice in printing of insoluble coloring agents on textile fabricsto print The water-dn-oll type of cellulose ether emulsion which has been found to be useful in carrying out this invention will contain a water-insoluble cellulose ether, as, for example, ethyl cellulose, propyl cellulose, butyl cellulose, benzyl cellulose, mixed ethyl benzyl cellulose, mixed ethyl 1 butyl cellulose, etc. A water-in-oil type of mulsuch colors from a paste containing the coloring agent in a soluble form and developing the insoluble coloron the fabric by suitable after-treatment. Such printing pastes have contained as carriers or thickeners such materials as starch and gum tragacanth. After the paste has been applied to the fabric and the color has.beco me fixed or developed on the fabric by some suitable treatment, the fabric is subjected to a washing treatment to remove the starch or gum carrier.
The color developing or fixing op ration is a very delicate operation subject to a wide variability in the final result; Insumcient developing or over developing are common reasons for rejection of the printed goods. Also, many delicate fabrics do not satisfactorily withstand the rather severe washing treatment necessary to remove the starch or'gum carrier and thus give printed fabrics of weakened strength.
It is an object of this invention to overcome the above disadvantages in textile printing.
It is another object to provide a printing paste containing an insoluble color pigment.
It is a further object to provide a method of printing textile fabrics with a printing paste containing an insoluble color pigment which eliminates the developing and washing treatments necessary in using the prior art'printing pastes and methods.
It is a further object to provide a printed'textile fabric in which an insoluble color pigment is bonded to the fabric by means of a novel bondin material.
Other objects of the invention will appear here- The objects above may be accomplished in ac- 'cordance with this invention by the preparation of printing pastes containing an insoluble color pigment dispersed in a carrier vehicle comprising a water-in-oil emulsion of a water-insoluble cellulose ether. The printing paste so formed is then applied to a textile fabric andthe fabric dried.
Since the insoluble color pigment isin its fully devolped state, no treatment on .the fabric is sion of a cellulose ether is particularly useful in this invention because of the high viscosity which such emulsions possess with very low solids content.
'I'he water-in-oil type of cellulose ether emulsion utilized in this invention may be prepared by first emulsifying a water-immiscible solvent solution of the cellulose ether, carrying out the emulsiflcation in water with the aid of a suitable emulsifying agent. If desired, a plasticizer for the cellulose ether or a suitable synthetic resin, or both. may be included in the solvent solution of the cellulose ether. The oil-in-water type of emulsion formed in this manner may then be reversed to a water-in-oil type of emulsion. In this manner, the cellulose ether solution becomes the continu-.
ous phase of the emulsion. Alternatively, a waterin-oil emulsion of the cellulose ether may be prepared directly without-the intermediate preparation of the oil-in-water type of emulsion.
As plasticizers for the cellulose ether; a solid or a liquid plasticizer may be used. Suitable plasticizers are hydrogenated methyl abietate, hydrogenated ethyl abietate, triphenyl phosphate, tributyl phosphate, methylphthalylmethyl glycollate, ethylphthalylethyl glycollate, etc.
As a suitable resin for use with the cellulose ether, a resin which is compatible with the cellulose ether, is resistant'to alkalies and exerts a softening action on the cellulose ether may be used. By softening action, I mean a lowering of the melting point of the cellulose ether and not necessarily a plasticizing of the cellulose ether-- in the strict sense of the term. Thus, I have found that rosin modified alkyd resins, such as rosin modified or hydrogenated rosin modified terpene-maleio"anhydride resins, rosin modified maleate resins, drying oil modified terpene-maleic anhydride resins, polymerized hydrocarbon resins,
such x as polymerized napthalene, polymerized coumaroneindene, or hydrogenated forms thereof, 100% phenolic resins, polyhydric alcohol esters of hydrogenated rosin, as well as other types having the above defined properties, may be used with w the cellulose ether. 1
necessary to develop the color, the only treatment necessary being the drying of the fabric to remove water and volatile solvent from the emulsion.
As emulsifying agents for preparing the emulsion of the cellulose ether with or without'a plas- 55 ticizer and with or without asuitable resin,.I may employ, for example, the alkali metal salts of the higher aliphatic half ester sulfates, as sodium lauryl sulfate, sodium stearyl sulfate, etc; sulfonated oils, as sulfonated castor oil, sulfonated olive soil, etc; soaps, as sodium stearate, potassium oleate, sodium oleate, etc; alkali metal salts of alkyl naphthalene sulfonic acids, as sodium butyl naphthalene sulfonate, sodium isopropyl naphthalene sulfonate, etc.
The cellulose ether, together with the plasticizer and the resin, if either or both are employed, will preferably be dissolved in a suitable water-immiscible solvent mixture before emulsification and the solvent solution emulsified in water by means of the emulsifying agent. Suit able solvent mixtures may include solvents such as, forexample, light aromatic hydrocarbons, as,
for example, toluol, xylol, Hi-Flash naphtha, etc.; petroleum hydrocarbons as, for example, Stoddard solvent, Solvesso No. 2, Solvesso No. 3, etc.; butanol; pine oil, etc. By Stoddard solvent, Solvesso No. 2, and Solvesso No. 3 are meant the petroleum hydrocarbon solvents known in the industry by those names. They may be generally characterized as follows:
The oil-in-water type of emulsion obtained according to the above description may be reversed so as to form a water-in-oil type of emulsion by addition of a suitable reversing agent as, for example, aluminum stearate, acetic acid, a mixture of pine oil and acetic acid, or an alkali, as potassium or sodium hydroxide, or by any other suitable means. If it is desirable to. prepare a water-inoil type emulsion directly, this may be done, for example, by adding one of the above reversing agents to the solvent solution of the cellulose ether and emulsifying in water with an emulsifying agent.
A water-in-oil type emulsion may also be prepared directly by stirring water and a suitable solvent into a water-immiscible solvent solution of a water-insoluble cellulose ether containing an insoluble pigment in dispersed form, then homogenizing the resulting water-in-oil type emulsion in a suitable colloid mill or homogenizer. If desired, the pigment may be first dispersed in the water and the emulsion prepared as above.
The insoluble color pigments which constitute an essential component of the printing pastes described in accordance with this invention may be either the inorganic or the organic coloring materials which are insoluble in either water or oil and are commonly used inprinting pastes. The organic pigments are those which consist either wholly or in part of dyestuffs which have been rendered insoluble in water and oil. These include those organic pigments which are made by precipitation on a suitable base. These also include the dyes which have been precipitated or rendered water-insoluble by various precipitating means such as barium chloride, lead acetate, tartaric acid, aluminum hydrate, etc., as well as the insoluble lakes and azo and diazo colors. Some of the more common insoluble color P18- scribed in accordance with this invention are known to the trade under the following names:

Ponsol Golden Orange G double paste (Color Index 1096) The printing pastes prepared and utilized in accordance with this invention may be prepared by mixing the insoluble color pigment such as described above into the water-in-oil emulsion of a water-insoluble cellulose ether to provide the improved printing paste. The body and thickness of the printing paste may be varied as desired by variation of the ingredients of the waterin-oil emulsion of the cellulose ether and by the amount of dissolved solids in the emulsion as well as by theamount of the solvent and by the amount of the color pigment added, and mixing the insoluble color pigment with the cellulose ether emulsion. It may be desirable inv some cases to include an auxiliary solvent, such as, for example, Stoddard solvent, Solvesso No. 2, pine oil, etc.
The solids content of the water-in-oil cellulose ether emulsion utilized in the printing paste will usually not be in excess of about 40% by weight and preferably will be within the range of about 1% to about 20%. The water-in-oil cellulose ether emulsion will be used in the printing paste usually in such an amount that the solids of the printing paste derived from the cellulose ether emulsion will not be in excess of about 10% of the total weight of the paste and preferably will be no more than about 6% of the total weight of the paste. The amount of insoluble color pigment included in the printing paste may be adjusted to provide the shade and quality of print desired and will depend to a large extent on the particular pigment employed, Generally speaking, the total solids content of the printing paste will not exceed about 20% by weight and preferably will be within the range of about 2% to about 15% by weight.
The method of applying a printing paste prepared in accordance with this invention to a textile fabric will involve the essential steps of applying the printing paste to the fabric by means of printing rollers or screens such as in screen printing followed by drying of the printed fabric in any suitable manner. The temperature of drying, for example, may be within the range of about 180 to about 320 F. and preferably may be within the range of about 220 to about 300 F. Developing of the color on the fabric or washing and soaping of the printed fabric are not necessary since development of the color is unnecessary and removal of the solids deposited from the cellulose ether emulsion is not desired and is not possible by washing and soap- 1 ing. The drying treatment to which the printed fabric is subjected merely removes the water and other volatile solvents contained "in the emulsion. 7
The printed fabric produced by printing a textile fabric with the printing paste described ments which may be used in printing pastes de- 75 above and according to the procedure described pastes.
above will be characterized as carrying in its printed areas an insoluble color pigment bonded to the fabric by means of the cellulose ether composition. Such cellulose ether composition may be a water-insoluble cellulose ether alone or mixed with either a plasticizer or a suitable synthetic resin, or both. The printed fabric is substantially resistant to crocking and is also resistant to laundering.
It will be further characterized by a uniformity of shade in the printed areas, and by a depth of shade which may be varied by the amount of color pigment incorporated into the printing paste.

The print exihibited substantial fastness to washing and crocking.
The printing pastes described above present several important advantages in the art of printing textiles over the printing pastes heretofore used. By printing with a paste containing an insoluble pigment, a greatly simplified printing procedure may be used. Thus, the steam and aging treatments required with use of prior printing pastes and also the washing and soaping treatments to remove the starch or gum carrier may be dispensed with, since with use of pigment no fixing or developing of the color on the fabric is necessary. The normal variations due to insufllcient developing or to over-developing are not encountered. A color uniformity of shade is, therefore, obtained with a minimum of variation. Also, the printed fabrics obtained in accordance with this invention exhibit a very satisfactory bonding of the pigment color to the cloth without materially altering the stifiness of the printed fabric in the printed areas. The elimination of the severe washing treatment usually given to printed fabrics to remove the starch or gum carrier makes it possible to provide delicate printed fabrics with their original strength.
It will be understood that the details and examples given hereinbefore are illustrative only and that the invention as broadly described and claimed is in no way limited thereby.
