- ABSTRACT The present invention relates to a process for dyeing fibers, fabrics or other shaped articles made from blends of either 1 poly(a1pha-olefins) or polyesters and various thermoplastic nitrogen-containing basic polymers to a multicolor pattern.
- the process of the present invention consists of treating shaped articles made from poly(alpha-olefins) or polyesters and a thermoplastic nitrogen-containing basic polymer in discontinuous fashion with a Lewis acid composition which optionally may contain anionic dyes, anionic surfactants and other modifiers, and then subsequently dyeing the treated article, if said anionic dyes are not used in the Lewis acid composition. Due to differences in affinity for different classes of dyes between treated and untreated areas of the shaped articles, multicolor dyeings will be obtained.
- the present invention thus provides a method of treatment for imparting local differences in affinity for different dye classes to a filamentary assembly, which term is used to denote a fiber, yarn, fabric or other shaped article, so that by exposure of such fiber, yarn, fabric or article, either at the time of treatment or subsequently, to dyes of different classes, a multicolor effect will be obtained.
- the base material used in this invention is an inherently undyeable or difficult to dye fiber, yarn, fabric or other shaped article made from a poly(alphaolefin) or polyester.
- this inherently undyeable material By blending this inherently undyeable material with a minor amount of a thermoplastic nitrogen-containing basic polymer capable of binding both disperse and anionic dyes, such material is made dyeable with disperse dyes, but is still impermeable and hence undyeable with anionic dyes.
- a thermoplastic nitrogen-containing basic polymer capable of binding both disperse and anionic dyes
- Dyeing the treated articles with anionic and optionally disperse dyes yields a multicolor effect, since the treated areas are dyeable with both anionic and disperse dyes, whereas the untreated areas are dyeable only with disperse d es.
- the process of the present invention includes the following steps as explained herein:
- an activating amount i.e., an amount sufficient to impart permeability to anionic dyes
- a Lewis acid composition which optionally contains a thickening agent, an anionic surfactant and anionic dyes.
- the processes entail incorporating a minor amount of a thermoplastic nitrogen-containing basic polymer in the poly(alpha-monoolefin) of polyester and, subsequent to the formation of fibers or other articles from the polymeric compositions, treating them with a Lewis acid capable of reacting with the basic polymer to form'an acid-base reaction product. This treatment renders these articles highly dyeable with anionic dyes.
- thermoplastic nitrogen-containing basic polymers does not render fibers, yams, fabrics or other shaped articles formed from such a polymeric composition substantially dyeable by anionic dyes.
- Such dyes will only impart very pale tints to such articles, so that for all practical purposes, they canbe said to be substantially undyeable by acid-type dyes.
- Such articles are substantially susceptible to dyeing by other classes of dyes, mainly the disperse dyes.
- anionic surfactants greatly enhances the uptake of anionic dyes by fibers or other shaped articles made from blends of alpha-olefin or polyester polymers with minor amounts (0.5 to 5 percent) of thermoplastic nitrogen-containing basic polymers and, optionally, similar amounts (0.5 to 5 percent) of hydrophilic compounds containing ethylene oxide units.
- the first fiber would be almost wholly undyeable with anionic dyes, while the second would have significant dyeability with anionic dyes.
- the activated portions of the two .poly( 3-methyll-butene fibers will show a similar difference in dyeability with anionic dyes as do the unactivated counterparts.
- the resultant product thus shows a tone-on-tone effect.
- the shaped articles, fabrics or fibers made from alpha-monoolefin polymers comprise a major portion of inherently undyeable alphamonoolefin polymers comprising both homopolymers and copolymers of alpha-monoolefins; for example, copolymers with non-terminal olefins or with one or more other alpha-olefins, as well as block copolymers of alpha-olefins with each other and graft copolymers of alpha-olefins with polymers of other alphaolefins.
- the class includes polyethylene, polypropylene, poly(4-methyll -pentene), copolymers of propylene and 4-methyl-l-pentene, and copolymers of any of the foregoing monomers with each other
- the vinyl-substituted monocyclic and polycyclic pyridine base dye-receptor polymers may be incorporated in the and/or with other copolymerizable monomers.
- the preferred material of this class is polypropylene, by which we mean any polymer of propylene and any copolymer containing predominantly polymerized propylene together with any other comonomer copolymerized therewith.
- polyester refers to polymers which are condensation polymers of dihydric alcohols with organo-dibasic acids or their anhydrides, particularly dicarboxylic acids, and self-condensation polymers of omega-hydroxy carboxylic acids.
- the preferred polyester materials in our in- 1 vention are poly(ethylene terephthalate), poly(ethylene terephthalate-isophthalate), and poly(l,4-cyclohexylenedimethylene terephthalate), and further discussion in terms of polyesters will be mainly in terms of these representative polyesters.
- polyesters in which the ester linkages are intralinear, including poly(alkylene alkanedioates), poly(cycloalkylenedimethylene alkanediotes), poly(alkylene arenedioates), poly(cycloalkylenedimethylene arenedioates), and analogous materials.
- Examples of the above-named polyesters are respectively, poly(ethylene adipate), p0ly( l ,4-cyclohexylenedimethylene adipate), poly(ethylene terephthalate), and poly(l,4-cyclohexylenedimethylene terephthalate).
- the basic dye receptor polymers which may be incorporated in the polyolefins or polyesters listed previously are thermoplastic basic nitrogen-containing materials capable of binding anionic and disperse dyes, and are illustrated by:
- Polyamides including condensation homopolymers and copolymers, in which the amide groups are an integral part of the polymer chain, and addition homopolymers and copolymers having pendant groups containing or consisting of amide groups.
- Amine polymers including condensation homopolymers and copolymers, in which the amine group is an integral part of the polymer chain, and addition homopolymers and copolymers having pendant groups which include or consist of amine groups.
- the basic nitrogen polymers employed should not be extractable from the mixtures thereof with the polyolefin or polyester under the conditions of treating and dyeing used, since of course this would lower or eliminate the dyeability.
- a l-hour extraction of the fiber or shaped article with boiling water at a pH of 3 for 1 hour should not extraet more than 90 percent of the originally added nitrogen polymer.
- the amount of the basic nitrogen polymer added to the polyolefin or polyester polymer should be sufiicient so that, after the acid treatment of the invention, it will bind the amount of dye required to produce the shade desired.
- hydrocarbon polymer either as a homopolymers, or as a copolymer with another vinyl-substituted pyridine or with any other vinyl monomer copolymerizable therewith, or as a graft copolymer with a hydrocarbon high polymer.
- the vinyl-substituted monoand polycyclic pyridine base dye receptor polymers used are those based, for example, or monovinylpyridines and monovinylquinolines.
- the monovinylpyridines useful in making the above named dye-receptive polymers employed in the invention include 2- vinylpyridine, 3-vinylpyridine, 4-vinylpyridine, S-methyl-Z- vinylpyridine, 2-ethyl-5-vinylpyridine, pyridine, 2-ethyl-6-vinylpyridine, 2-isopropenylpyridine, etc.
- Polymerizable olefinic monomers with which the monovinylpyridine may be copolymerized include acrylic and methacrylic esters typified by ethyl acrylate and methyl methacrylate, vinyl aryl hydrocarbons typified by styrene and vinyltoluenes, and butadiene--l,3.
- the monovinylpyridine may be graft-copolymerized, by well-known methods, with a previously formed linear high polymer, typified by polyethylene, polypropylene, polystyrene, and polybutadiene.
- a hydrophilic compound containing ethylene oxide units (-CH -CH -O-) is incorporated into blends containing a polyolefin or a polyester it is preferable to employ nitrogen base polymers containing pyridinic groups only, (i.e., ones which are not copolymerized with non-nitrogen base monomers.) It is always desirable that the basic polymer contain no more than a minor proportion of non-basic material copolymerized with a monovinylpyridine, since only the pyridine portion of the polymer additive is active in enhancing dyeability.
- the polyamides useful as the dye-receptors employed in this process include homopolyamides such as poly(hexamethylene adipamide), poly(hexamethylene sebacamide), polypyrrolidinone, polycaprolactam, polyenantholactam, and copolyamides such as Zytel 61 (a trademark of du Pont de Nemours and Company), an interpolymer of hexamethylene adipamide and hexamethylene sebacamide with caprolactam.
- homopolyamides such as poly(hexamethylene adipamide), poly(hexamethylene sebacamide), polypyrrolidinone, polycaprolactam, polyenantholactam, and copolyamides such as Zytel 61 (a trademark of du Pont de Nemours and Company), an interpolymer of hexamethylene adipamide and hexamethylene sebacamide with caprolactam.
- vinyl polymers with pendant groups consisting of or containing amide groups there are the substituted poly(vinylpyrrolidinones), (e.g., polymers of N-vinyl-3-alkylpyrrolidinone) and N-substituted polyacrylamides, (e.g., N- butylacrylamide).
- substituted poly(vinylpyrrolidinones) e.g., polymers of N-vinyl-3-alkylpyrrolidinone
- N-substituted polyacrylamides e.g., N- butylacrylamide
- copolymers of the amidecontaining vinyl monomers with other olefinic monomers such as acrylic and methacrylic esters typified by ethyl acrylate and methyl methacrylate, vinylaryl hydrocarbons typified by styrene and vinyltoluenes, and butadiene-l,3.
- the vinylpyrrolidinones or acrylamides may be graftcopolymerized, by well-known methods, with a previously formed linear high polymer, typified by polyethylene, polypropylene, polystyrene, and polybutadiene. It is always desirable that the basic polymer contain no more than a minor proportion of material copolymerized with the vinylpyrrolidinones or acrylamides, since only the amide portion of the polymer additive is active in enhancing the dyeability of the hydrocarbon polymer.
- amine polymers useful as the dye receptor employed in this invention there are the condensation products of epihalohydrins or dihaloparafiins with one or more amines, such as those disclosed in Belgian Pat. No. 606,306, exemplified by the condensation product of dodecylamine, piperazine and epichlorohydrin; as examples of addition polymers with pendant groups consisting of or containing amines there are the reaction product of a styrenemaleic anhydride copolymer with 3-(dimethylamino) propylamine (the product being a polyamino-polyimide), and styrene-allylamine copolymers such as those disclosed in U.S. Pat. No. 2,456,428.
- hydrophilic compounds optionally blended in the amounts of about 0.5 and 7 percent with the hydrocarbon polymer or polyester used in this invention, are selected from the following groups of compounds:
- Polyethylene glycol also referred to herein as PEG having a degree of polymerization (DP) of at least 4.
- Copolymers of ethylene oxide with other alkylene oxides having a degree of polymerization of the ethylene oxide units of at least 4 and containing a minimum of 60 percent by weight ethylene oxide. These compounds are exemplified by the series of block copolymers produced by condensing ethylene oxide with a product formed by the condensation of propylene oxide with propylene glycol (formula of such copolymers: HO(C H O) ,.(C H O),H) and sold under the trademark Pluronic). Other useful copolymers are derived from the polymerization of ethylene oxide and propylene 0xide.
- polyethylene glycol such as its ethers and esters having a degree of polymerization of ethylene oxide of at least 4 and an ethylene oxide content of at least 60 percent by weight.
- examples of such derivatives are: (a) polyethylene glycol alkyl ethers; (b) alkylaryl polyethoxyalcohols sold under the trademark Triton" (octylphenylpolyethoxy ethanol series); (c) polyoxyethylene derivatives of long chain fattyacid esters of hexitol anhydrides including sorbitans, sorbides, mannitans and mannides, such as polyethylene glycol hexitol carboxylates, polyoxyethylene sorbitan' monolaurate sold under the trademark Tween and polyoxyethylene sorbitan monostearate; and polyethylene glycol carboxylate esters such as polyethylene polyethylene glycol distearate.
- the mixtures of the hydrocarbon polymer or polyester and the nitrogen-containing dye receptor polymers are made by blending, tumbling or any convenient method and then can be shaped by vacuum molding, extrusion or in the case of fibers, may be spun into yarns using a conventional melt spinning process.
- the articles made from the polymer blend are treated with the Lewis acid composition after shaping. If the article to be treated is a fabric made from yarns, the physical form of said fibers which are woven into the fabric may vary widely. They may be monofilament or multifilament; plain, bulked or texturized; staple, tow or stock.
- the treatment with the Lewis acid composition may be done in any convenient fashion such as roller printing, screen printing, spraying or dipping.
- a thickener which is compatible with the Lewis acid may be employed to prevent migration, which is the tendency of the applied activating material to diffuse or wick away from the site of original application and thus produce a blurred rather than a sharply defined area.
- the duration of the acid activation treatment with the Lewis acid composition may be from a few seconds to several hours, but for practical reasons is preferably kept between 10 seconds to minutes duration.
- it may be heated at a temperature below the melting temperature of the material.
- a temglycol monostearate and perature not greater than 140 C. for poly(alpha-olefins) and a 200 C. for polyesters is satisfactory and sufficient in most cases.
- the activating material which is used in accordance with the present invention may contain, in addition to the Lewis acid, an anionic surfactant, an anionic dyestufi and a suitable amount of water and thickening agent to form a paste of desired consistency.
- an anionic surfactant an anionic dyestufi and a suitable amount of water and thickening agent to form a paste of desired consistency.
- Concentrated inorganic acids such as hydrochloric acid, hydrobromic acid, sulfurous acid, nitric acid, sulfuric acid, phosphoric acid and perchloric acid, or the anhydrides thereof.
- Organic carboxylic and sulfonic acids including aliphatic, aromatic, hydroxy-substituted aromatic acids, monocarboxylic and dicarboxylic acids, monosulfonic and disulfonic, saturated and unsaturated acids.
- Suitable acids are exemplified by formic, acetic, propionic, stearic, and other alkanoic acids in the C C range, undecylenic, oleic, benzoic, salicyclic, succinic, adipic, phthalic, bromoacetic, benzenesulfonic, ptoluenesulfonic, chloroacetic and lactic acids.
- Examples of preferred acids used in the present invention are hydrochloric, formic, acetic, monoor dichloroacetic and para-toluenesulfonic acids.
- Any Lewis acid or Lewis acid generating material which can be applied to the yarn, fabric or shaped article may be used, including hydrolyzable halides such as aluminum, zinc and tin halides, benzylic halides, allylic halides, acyl halides and sulfonyl halides, phenols, borate esters and the like.
- the acid may be used in the liquid or molten state (when its melting point is below the temperature selected for the treatment) or in solution in an aqueous or organic solvent.
- the concentration of the Lewis acid used in the activating composition of the present invention is not critical since low concentrations of the acid may be applied in solution in a volatile solvent, with the solvent being evaporated during the heating period. Concentrations of Lewis acid in the activating composition of between 4 and percent (on the weight of treating composition) are the most convenient, when used in the absence of anionic surfactants. Lower concentrations (i.e., between about 0.l and 4 percent) as well as the higher ones are operative in the presence of anionic surfactants.
- the anionic surfactants optionally employed in the present invention have the general formula (R-A) wherein R represents a hydrophobic group which is either a substituted or non-substituted alkyl, aryl, or alkylaryl group having six or more carbon atoms (preferably between nine and 40 carbon atoms) per A group; and A is an anionic group exemplified by one or more of the following groups:-(l) sulfonate; (2) sulfate; (3) phosphate or polyphosphate; 4) carboxylate etc.
- the A group can be in the free acid form or in the salt form, but acid conditions (i.e., a pH of about 5 or less) must always be present.
- Another type of anionic surfactant which can be used is one wherein R may contain a polyoxyalkylene group. Additional operative materials include those generating anionic surfactants in situ during the process of this invention. Examples of useable anionic surfactants are:
- Lewisacid-containing activating compositions of the present invention are frequently applied by conventional textile printing techniques which involve thickening them so they spreading of the applied pattern, as desired.
- Other dyeing assistants such as retarding agents, wetting agents and leveling agents may likewise be added to the activating paste in accordance with the effects to be obtained.

- anionic dyes which may be used in this invention are the direct dyes typified by the following:
- Direct Yellow 44 (CI. No. 29000) Direct Red 13 (CI. No. 22155) Direct Blue 67 (Cl. No. 27925
- Other categories of anionic dyes which are applicable to our invention are the reactive dyes, typified by Reactive Orange 1, and the mordant acid dyes, typified by Mordant Red 3 (O1. No. 5 8005
- disperse dyes may also be used in the present invention, as previously described. Examples of this class are:
- Disperse Yellow 23 (Cl. No. 26070) Disperse Orange 21 Disperse Blue 27 (CI. No. 60667) Cibacete Pink FG Disperse Yellow 42 (CJ. No. 10338) Interchem Blue RLF 40
- the dye penetration intothe Lewis acid-treated yarn fabric or shaped article is increased 7 and deeper colors are produced when the activating paste is heated. This can be accomplished by heating the fabric or shaped article with the paste thereon to a temperature below the melting point of the polymers used (i.e., to 200 C.), or the paste may be heated prior to application to the article. If the paste includes a dye, both activation and dyeing are accelerated by the heating step.
- dyeing is carried out subsequent to the treatment, which has the practical advantage than an undyed fabric may be stored and then dyed to any desired two- (or multicolor with natural or pigmented yarns) shade as needed.
- heating step either steam or dry heat may be used. Steam at about 100 C. for 3 to 20 minutes is, however, preferred for optimum results.
- EXAMPLE 1 A blend of 97.1% isotactic polypropylene and 2.9 percent poly-2-vinylpyridine was melt-spun into fiber, drawn 5:1 and the resultant yarn knit into tubular fabric.
- An activating paste was prepared by mixing 100 grams of 90 percent formic acid, 10 grams of hydroxyethylcellulose and 10 grams water. The activating paste was printed on a sample of the tubular fabric in the form of an X. The treated fabric was then heated on a ferrotype plate at 260 F. for 10 minutes, and then rinsed in water containing a small amount of nonionic detergent which is the nonylphenol/ethylene oxide condensate known as Triton X-100. After being scoured at 93 C.
- the fabric was dyed for 1 hour at 200 F in a dyebath containing 3 percent owf (on the weight of fiber) Capracyl Orange R (Acid Orange 60) and 3 percent owf Calcosperse Yellow 4 RL (Disperse Yellow 23). The fabric was finally post-scoured for 10 minutes at F. in water containing a small amount of nonionic detergent.
- the sample was dyed orange where the acid-containing activation paste had been applied and yellow where it had not been applied. The contrast was marked and the borders were clearly defined.
- Example 2 The procedure of Example 1 was duplicated except that methylcellulose was used as thickener, and spots of paste, rather than an X, were applied to the fabric. After scouring, the fabric was dyed as in Example 1, using only Capracyl Orange R. After dyeing, orange spots resulted where the paste had been applied, while the untreated areas were colored only a very pale pink.
- the face yarn of the carpet was printed with a paste made up of 3 percent Neolan Red BRE (Acid Red 212), 5 percent Lyogen VU (a nonionic alkylphenolpolyether glycol used as levelling agent), 5 percent Polygum 261, a purified natural gum ether thickening agent, 6 percent formic acid and 81 percent water.
- the carpet containing the paste thereon was put into a saturated steam atmosphere at 212 F. for 20 minutes, removed from the atmosphere and scoured for five minutes at 140 F. with an aqueous solution containing 0.5 percent owf Triton X-100.
- a carpet having a red pattern printed on it resulted, with good pattern definition of the printed area and negligible migration into and staining of the unprinted area.
- EXAMPLE 4 A carpet prepared as in Example 3 was printed with paste containing 3 percent Crocein Scarlet SS (Acid Red 73, C.l. No. 27090), 5 percent Polygum 261, anatural purified gum ether thickening agent, 40 percent of a 1:1 mixture of monochloroand dichloroacetic acid, 7 0.1 percent Triton X-100 and 51.9 percent water.

Primary Examiner-George F. Lesmes Assistant ExaminerPatricia C. Ives Attorney-Thomas A. Beck [57] ABSTRACT The present invention relates to a process for dyeing fibers, fabrics or other shaped articles made from blends of either 1 poly(a1pha-olefins) or polyesters and various thermoplastic nitrogen-containing basic polymers to a multicolor pattern.
50 Claims, No Drawings Cappuccio et a1. ..18/54 MIXTURE F FILAMENTS CAPABLE OF BEING DYED TO A MULTICOLOR PATTERN WITH ANIONIC DISPERSE DYES The process of the present invention consists of treating shaped articles made from poly(alpha-olefins) or polyesters and a thermoplastic nitrogen-containing basic polymer in discontinuous fashion with a Lewis acid composition which optionally may contain anionic dyes, anionic surfactants and other modifiers, and then subsequently dyeing the treated article, if said anionic dyes are not used in the Lewis acid composition. Due to differences in affinity for different classes of dyes between treated and untreated areas of the shaped articles, multicolor dyeings will be obtained. The present invention thus provides a method of treatment for imparting local differences in affinity for different dye classes to a filamentary assembly, which term is used to denote a fiber, yarn, fabric or other shaped article, so that by exposure of such fiber, yarn, fabric or article, either at the time of treatment or subsequently, to dyes of different classes, a multicolor effect will be obtained.
The base material used in this invention is an inherently undyeable or difficult to dye fiber, yarn, fabric or other shaped article made from a poly(alphaolefin) or polyester. By blending this inherently undyeable material with a minor amount of a thermoplastic nitrogen-containing basic polymer capable of binding both disperse and anionic dyes, such material is made dyeable with disperse dyes, but is still impermeable and hence undyeable with anionic dyes. When fibers, yarns, fabrics or other shaped articles are made from the above-described blends, and localized areas of said articles are treated with Lewis acid or Lewis acid generating material compositions as described herein, the treated areas are rendered highly dyeable with anionic dyes. Dyeing the treated articles with anionic and optionally disperse dyes, either at the time of treatment or subsequently, yields a multicolor effect, since the treated areas are dyeable with both anionic and disperse dyes, whereas the untreated areas are dyeable only with disperse d es.
The process of the present invention includes the following steps as explained herein:
1. Blending between about 0.5 and 5 percent of a thermoplastic nitrogen-containing basic polymer capable of binding anionic (i.e., acid-type) dyes, and optionally between about 0.5 and 5 percent of a hydrophilic compound containing ethylene oxide groups, with a fiber-forming poly(alphamonoolefin) or polyester.
2. Forming said resulting blend into a fiber, yarn, fabric or other shaped article.
3. Optionally dyeing said shaped article with a disperse dye.
4. Contacting desired portions of said shaped article with an activating amount (i.e., an amount sufficient to impart permeability to anionic dyes) of a Lewis acid composition which optionally contains a thickening agent, an anionic surfactant and anionic dyes.
5. If desired, heating said shaped article in contact with said Lewis acid composition to accelerate penetration of the Lewis acid composition into the shaped article.
6. Removing the excess of Lewis acid composition from the treated article by rinsing, soaping, scouring or the like.
7. Dyeing the treated article, if desired, with an anionic dye, either alone or simultaneously or consecutively with a different disperse dye, if the article was previously dyed with a disperse dye.
U.S. Pat. No. 3,361,843 and U.S. Pat. No. 3,432,250 filed Mar. 16, 1964, both by Robert Miller, Frederick C. Loveless and Milton Farber, describe processes whereby undyeable or difficult to dye hydrocarbon high polymers and polyesters are rendered deeply dyeable by anionic dyes to which they are normally inert without deleteriously affecting the physical properties of the articles formed from the polymer. Briefly, the processes entail incorporating a minor amount of a thermoplastic nitrogen-containing basic polymer in the poly(alpha-monoolefin) of polyester and, subsequent to the formation of fibers or other articles from the polymeric compositions, treating them with a Lewis acid capable of reacting with the basic polymer to form'an acid-base reaction product. This treatment renders these articles highly dyeable with anionic dyes.
As is explained in the above-mentioned disclosures, the incorporation of minor amounts of thermoplastic nitrogen-containing basic polymers in a polyolefin or polyester does not render fibers, yams, fabrics or other shaped articles formed from such a polymeric composition substantially dyeable by anionic dyes. Such dyes will only impart very pale tints to such articles, so that for all practical purposes, they canbe said to be substantially undyeable by acid-type dyes. Such articles, however, are substantially susceptible to dyeing by other classes of dyes, mainly the disperse dyes.
After the treatment with Lewis acids (activation).of articles made from mixtures of polyolefins or polyesters with minor amounts (between 0.5 to 10 percent, but preferably 0.5 to 5 percent, since there is some uptake of anionic dye at the higher levels) of the basic nitrogen-containing polymers according to the process of the said patent and pending application, these fibers become highly susceptible to dyeing by anionic dyes and can readily be dyed to desirable deep shades by them.
Copending U.S. patent application Ser. No. 679,618, by Andor Schwarcz, filed Nov. 1, 1967, now U.S. Pat. No. 3,530,201, describes the use of hydrophilic compounds containing ethylene oxide units along with the basic nitrogen-containing polymers to yield acid-dyeable shaped articles and fibers from poly-alpha-olefins and polyesters.
According to copending patent application Ser. No. 705,303, filed Feb. 14, 1968, by Andor Schwarcz and Charles Brown, application of anionic surfactants under acid conditions greatly enhances the uptake of anionic dyes by fibers or other shaped articles made from blends of alpha-olefin or polyester polymers with minor amounts (0.5 to 5 percent) of thermoplastic nitrogen-containing basic polymers and, optionally, similar amounts (0.5 to 5 percent) of hydrophilic compounds containing ethylene oxide units.
Copending U.S. Pat. No. 3,439,999 to RobertMiller and Milton Farber, describes a method of attaining a multicolor effect from a single dyeing step by dyeing fabrics containing yarns made according to U.S. Pat. No. 3,361,843 or U.S. Pat. No. 3,432,250 and other yarns not treated with the Lewis acid.
We have now discovered a new and novel method for producing multicolor effects on fibers, yarns or other shaped articles made from the above described modified polyolefins or polyesters. For the purposes of discussion in this disclosure this method is entitled discontinuous activation, which means that the fiber, or shaped article is treated with the Lewis acid only in certain areas or portions of the fiber, fabric or article, according to the wishes of the processor. When the article treated in this fashion is subsequently exposed to a dyebath, only the activated areas (i.e., areas treated by discontinuous activation) will absorb anionic dyes, whereas both treated and untreated areas will absorb disperse dyes. The
result will be a two-color dyed effect. When more than two colors are desired this may be achieved by mixing different dyes separately with the Lewis acid and applying each mixture of dye-Lewis acid separately to the article. Still another means for attaining multicolor effects would be by including natural (i.e., uncolored) or pigmented yarns in a polyolefin or polyester fabric. Tone-on-tone effects, i.e., different intensities of the same color, may also be achieved alone or in combination with multicolor effects, by using combinations of fibers in the yarn or fabric, wherein one fiber is made from a polyolefin or polyester containing dye receptor alone and the other fiber from polyolefin or polyester containing both dye receptor and hydrophilic compound containing ethylene oxide groups. The first fiber would be almost wholly undyeable with anionic dyes, while the second would have significant dyeability with anionic dyes. The activated portions of the two .poly( 3-methyll-butene fibers will show a similar difference in dyeability with anionic dyes as do the unactivated counterparts. The resultant product thus shows a tone-on-tone effect.
In the present invention, the shaped articles, fabrics or fibers made from alpha-monoolefin polymers comprise a major portion of inherently undyeable alphamonoolefin polymers comprising both homopolymers and copolymers of alpha-monoolefins; for example, copolymers with non-terminal olefins or with one or more other alpha-olefins, as well as block copolymers of alpha-olefins with each other and graft copolymers of alpha-olefins with polymers of other alphaolefins. The class includes polyethylene, polypropylene, poly(4-methyll -pentene), copolymers of propylene and 4-methyl-l-pentene, and copolymers of any of the foregoing monomers with each other The vinyl-substituted monocyclic and polycyclic pyridine base dye-receptor polymers may be incorporated in the and/or with other copolymerizable monomers. The preferred material of this class is polypropylene, by which we mean any polymer of propylene and any copolymer containing predominantly polymerized propylene together with any other comonomer copolymerized therewith.
The term polyester as used herein refers to polymers which are condensation polymers of dihydric alcohols with organo-dibasic acids or their anhydrides, particularly dicarboxylic acids, and self-condensation polymers of omega-hydroxy carboxylic acids. The preferred polyester materials in our in- 1 vention are poly(ethylene terephthalate), poly(ethylene terephthalate-isophthalate), and poly(l,4-cyclohexylenedimethylene terephthalate), and further discussion in terms of polyesters will be mainly in terms of these representative polyesters. It will be understood however, that the invention is applicable'to'all fiber-forming polyesters, in which the ester linkages are intralinear, including poly(alkylene alkanedioates), poly(cycloalkylenedimethylene alkanediotes), poly(alkylene arenedioates), poly(cycloalkylenedimethylene arenedioates), and analogous materials. Examples of the above-named polyesters are respectively, poly(ethylene adipate), p0ly( l ,4-cyclohexylenedimethylene adipate), poly(ethylene terephthalate), and poly(l,4-cyclohexylenedimethylene terephthalate).
The basic dye receptor polymers which may be incorporated in the polyolefins or polyesters listed previously are thermoplastic basic nitrogen-containing materials capable of binding anionic and disperse dyes, and are illustrated by:
1. Polymers of vinyl-substituted monoand polycyclic pyridines, either homopolymers or copolymers with each other, or with other vinyl compounds, including graft copolymers.
2. Polyamides, including condensation homopolymers and copolymers, in which the amide groups are an integral part of the polymer chain, and addition homopolymers and copolymers having pendant groups containing or consisting of amide groups.
3. Amine polymers, including condensation homopolymers and copolymers, in which the amine group is an integral part of the polymer chain, and addition homopolymers and copolymers having pendant groups which include or consist of amine groups.
Other basic nitrogen polymers which may be used in this process are polyurethanes, poly(vinylcarbazoles), aniline-formaldehyde resins, etc. The major requirement for the type of structure of this nitrogen containing material is that it be capable of binding anionic dyes.
The basic nitrogen polymers employed should not be extractable from the mixtures thereof with the polyolefin or polyester under the conditions of treating and dyeing used, since of course this would lower or eliminate the dyeability. As a diagnostic test, a l-hour extraction of the fiber or shaped article with boiling water at a pH of 3 for 1 hour should not extraet more than 90 percent of the originally added nitrogen polymer. The amount of the basic nitrogen polymer added to the polyolefin or polyester polymer should be sufiicient so that, after the acid treatment of the invention, it will bind the amount of dye required to produce the shade desired.
hydrocarbon polymer either as a homopolymers, or as a copolymer with another vinyl-substituted pyridine or with any other vinyl monomer copolymerizable therewith, or as a graft copolymer with a hydrocarbon high polymer. The vinyl-substituted monoand polycyclic pyridine base dye receptor polymers used are those based, for example, or monovinylpyridines and monovinylquinolines.
The monovinylpyridines useful in making the above named dye-receptive polymers employed in the invention include 2- vinylpyridine, 3-vinylpyridine, 4-vinylpyridine, S-methyl-Z- vinylpyridine, 2-ethyl-5-vinylpyridine, pyridine, 2-ethyl-6-vinylpyridine, 2-isopropenylpyridine, etc. Polymerizable olefinic monomers with which the monovinylpyridine may be copolymerized include acrylic and methacrylic esters typified by ethyl acrylate and methyl methacrylate, vinyl aryl hydrocarbons typified by styrene and vinyltoluenes, and butadiene--l,3. Alternatively,.the monovinylpyridine may be graft-copolymerized, by well-known methods, with a previously formed linear high polymer, typified by polyethylene, polypropylene, polystyrene, and polybutadiene. ln instances where a hydrophilic compound containing ethylene oxide units (-CH -CH -O-) is incorporated into blends containing a polyolefin or a polyester it is preferable to employ nitrogen base polymers containing pyridinic groups only, (i.e., ones which are not copolymerized with non-nitrogen base monomers.) It is always desirable that the basic polymer contain no more than a minor proportion of non-basic material copolymerized with a monovinylpyridine, since only the pyridine portion of the polymer additive is active in enhancing dyeability.
The polyamides useful as the dye-receptors employed in this process include homopolyamides such as poly(hexamethylene adipamide), poly(hexamethylene sebacamide), polypyrrolidinone, polycaprolactam, polyenantholactam, and copolyamides such as Zytel 61 (a trademark of du Pont de Nemours and Company), an interpolymer of hexamethylene adipamide and hexamethylene sebacamide with caprolactam.
As examples of vinyl polymers with pendant groups consisting of or containing amide groups there are the substituted poly(vinylpyrrolidinones), (e.g., polymers of N-vinyl-3-alkylpyrrolidinone) and N-substituted polyacrylamides, (e.g., N- butylacrylamide). Also usable are copolymers of the amidecontaining vinyl monomers with other olefinic monomers such as acrylic and methacrylic esters typified by ethyl acrylate and methyl methacrylate, vinylaryl hydrocarbons typified by styrene and vinyltoluenes, and butadiene-l,3. Alternatively, the vinylpyrrolidinones or acrylamides may be graftcopolymerized, by well-known methods, with a previously formed linear high polymer, typified by polyethylene, polypropylene, polystyrene, and polybutadiene. It is always desirable that the basic polymer contain no more than a minor proportion of material copolymerized with the vinylpyrrolidinones or acrylamides, since only the amide portion of the polymer additive is active in enhancing the dyeability of the hydrocarbon polymer.
As examples of amine polymers useful as the dye receptor employed in this invention there are the condensation products of epihalohydrins or dihaloparafiins with one or more amines, such as those disclosed in Belgian Pat. No. 606,306, exemplified by the condensation product of dodecylamine, piperazine and epichlorohydrin; as examples of addition polymers with pendant groups consisting of or containing amines there are the reaction product of a styrenemaleic anhydride copolymer with 3-(dimethylamino) propylamine (the product being a polyamino-polyimide), and styrene-allylamine copolymers such as those disclosed in U.S. Pat. No. 2,456,428.
The hydrophilic compounds, optionally blended in the amounts of about 0.5 and 7 percent with the hydrocarbon polymer or polyester used in this invention, are selected from the following groups of compounds:
2-methyl-5-vinyll. Polyethylene glycol (also referred to herein as PEG) having a degree of polymerization (DP) of at least 4.
2. Copolymers of ethylene oxide with other alkylene oxides having a degree of polymerization of the ethylene oxide units of at least 4 and containing a minimum of 60 percent by weight ethylene oxide. These compounds are exemplified by the series of block copolymers produced by condensing ethylene oxide with a product formed by the condensation of propylene oxide with propylene glycol (formula of such copolymers: HO(C H O) ,.(C H O),H) and sold under the trademark Pluronic). Other useful copolymers are derived from the polymerization of ethylene oxide and propylene 0xide.
3. Derivatives of polyethylene glycol, such as its ethers and esters having a degree of polymerization of ethylene oxide of at least 4 and an ethylene oxide content of at least 60 percent by weight. Examples of such derivatives are: (a) polyethylene glycol alkyl ethers; (b) alkylaryl polyethoxyalcohols sold under the trademark Triton" (octylphenylpolyethoxy ethanol series); (c) polyoxyethylene derivatives of long chain fattyacid esters of hexitol anhydrides including sorbitans, sorbides, mannitans and mannides, such as polyethylene glycol hexitol carboxylates, polyoxyethylene sorbitan' monolaurate sold under the trademark Tween and polyoxyethylene sorbitan monostearate; and polyethylene glycol carboxylate esters such as polyethylene polyethylene glycol distearate.
The mixtures of the hydrocarbon polymer or polyester and the nitrogen-containing dye receptor polymers are made by blending, tumbling or any convenient method and then can be shaped by vacuum molding, extrusion or in the case of fibers, may be spun into yarns using a conventional melt spinning process. The articles made from the polymer blend are treated with the Lewis acid composition after shaping. If the article to be treated is a fabric made from yarns, the physical form of said fibers which are woven into the fabric may vary widely. They may be monofilament or multifilament; plain, bulked or texturized; staple, tow or stock. The treatment with the Lewis acid composition may be done in any convenient fashion such as roller printing, screen printing, spraying or dipping. By means known to those skilled in the art, random or regular color effects can be produced. If a sharply defined pattern or design is desired, a thickener which is compatible with the Lewis acid may be employed to prevent migration, which is the tendency of the applied activating material to diffuse or wick away from the site of original application and thus produce a blurred rather than a sharply defined area. The duration of the acid activation treatment with the Lewis acid composition may be from a few seconds to several hours, but for practical reasons is preferably kept between 10 seconds to minutes duration. In order to hasten diffusion of the Lewis acid and the other modifiers present in the activating material into the treated article, it may be heated at a temperature below the melting temperature of the material. Usually a temglycol monostearate and perature not greater than 140 C. for poly(alpha-olefins) and a 200 C. for polyesters is satisfactory and sufficient in most cases.
The activating material which is used in accordance with the present invention, may contain, in addition to the Lewis acid, an anionic surfactant, an anionic dyestufi and a suitable amount of water and thickening agent to form a paste of desired consistency. The following are examples of the Lewis acids which may be used in the present invention. They are illustrative and in no way limiting:
l. Concentrated inorganic acids such as hydrochloric acid, hydrobromic acid, sulfurous acid, nitric acid, sulfuric acid, phosphoric acid and perchloric acid, or the anhydrides thereof.
2. Organic carboxylic and sulfonic acids including aliphatic, aromatic, hydroxy-substituted aromatic acids, monocarboxylic and dicarboxylic acids, monosulfonic and disulfonic, saturated and unsaturated acids. Suitable acids are exemplified by formic, acetic, propionic, stearic, and other alkanoic acids in the C C range, undecylenic, oleic, benzoic, salicyclic, succinic, adipic, phthalic, bromoacetic, benzenesulfonic, ptoluenesulfonic, chloroacetic and lactic acids.
Examples of preferred acids used in the present invention are hydrochloric, formic, acetic, monoor dichloroacetic and para-toluenesulfonic acids. Any Lewis acid or Lewis acid generating material which can be applied to the yarn, fabric or shaped article may be used, including hydrolyzable halides such as aluminum, zinc and tin halides, benzylic halides, allylic halides, acyl halides and sulfonyl halides, phenols, borate esters and the like. The acid may be used in the liquid or molten state (when its melting point is below the temperature selected for the treatment) or in solution in an aqueous or organic solvent. The concentration of the Lewis acid used in the activating composition of the present invention is not critical since low concentrations of the acid may be applied in solution in a volatile solvent, with the solvent being evaporated during the heating period. Concentrations of Lewis acid in the activating composition of between 4 and percent (on the weight of treating composition) are the most convenient, when used in the absence of anionic surfactants. Lower concentrations (i.e., between about 0.l and 4 percent) as well as the higher ones are operative in the presence of anionic surfactants.
The anionic surfactants optionally employed in the present invention have the general formula (R-A) wherein R represents a hydrophobic group which is either a substituted or non-substituted alkyl, aryl, or alkylaryl group having six or more carbon atoms (preferably between nine and 40 carbon atoms) per A group; and A is an anionic group exemplified by one or more of the following groups:-(l) sulfonate; (2) sulfate; (3) phosphate or polyphosphate; 4) carboxylate etc. The A group can be in the free acid form or in the salt form, but acid conditions (i.e., a pH of about 5 or less) must always be present. Another type of anionic surfactant which can be used is one wherein R may contain a polyoxyalkylene group. Additional operative materials include those generating anionic surfactants in situ during the process of this invention. Examples of useable anionic surfactants are:

Any concentration above about 0.5 percent of anionic surfactant in the Lewis acid treating composition is operative but concentrations in said composition between about 0.5 and'5 percent are preferred. Attendant to this are savings in cost, the use of less expensive metals and alloys in storage and application equipment, decreased corrosion anclv lower toxicity hazards. Their incorporation in the activating composition is thus highly beneficial. v I
The Lewisacid-containing activating compositions of the present invention are frequently applied by conventional textile printing techniques which involve thickening them so they spreading of the applied pattern, as desired. Other dyeing assistants, such as retarding agents, wetting agents and leveling agents may likewise be added to the activating paste in accordance with the effects to be obtained.
When dyeing is subsequent to activation, a two-color dyed effect may be realized with the treated yarn, fabric or shaped article. By incorporating dyes in the activating paste, however, multiple-pass printing techniques may be used with different dyes in separate pastes to achieve multicolor eflects. By dyeing the entire fabric with a disperse dye prior to activation, and then printing with the activating paste, over-printed ef-' fects may be obtained. Swelling agents (carriers) to open the fiber to dyes, such as ortho-dichlorobenzene, aromatic hydrocarbons, etc. may be used in the paste, but the effect of the present invention does not depend upon the use of a carrier. The following anionic dyes can be utilized in the practice of the present invention:
Strong Acid Dyes Acid Yellow 23 (Cl. No. 19140) Acid Orange 7 (CI. No. 15510) Acid Red 73 (CI. No. 27290) Acid Blue 25 (Cl. No. 62055) Acid Blue 78 (CI. No. 62105) Acid Metallized Dyes Acid Yellow 54 (C1. No. 19010) Acid Orange 72 (CI. No. 18740) Acid Red 186 (C1. No. 18810) Acid Red 212 Acid Blue 158 (CI. No. 14880) Acid Black 52 (CI. No. 15711) Neutral Metallized Dyes Acid Yellow 121 (C. 1. No. 18690) Acid Orange 60 (The half-chrome complex of l-phenyl-3- methyl-4-(2-hydroxy-5-sulfamoyl phenylazo)-5- pyrazolone) Acid Red 209 Acid Blue 168 Acid Black 60 Another category of anionic dyes which may be used in this invention are the direct dyes typified by the following:
Direct Yellow 44 (CI. No. 29000) Direct Red 13 (CI. No. 22155) Direct Blue 67 (Cl. No. 27925 Other categories of anionic dyes which are applicable to our invention are the reactive dyes, typified by Reactive Orange 1, and the mordant acid dyes, typified by Mordant Red 3 (O1. No. 5 8005 In addition to anionic dyes, disperse dyes may also be used in the present invention, as previously described. Examples of this class are:
Disperse Yellow 23 (Cl. No. 26070) Disperse Orange 21 Disperse Blue 27 (CI. No. 60667) Cibacete Pink FG Disperse Yellow 42 (CJ. No. 10338) Interchem Blue RLF 40 As indicated herein previously the dye penetration intothe Lewis acid-treated yarn fabric or shaped article is increased 7 and deeper colors are produced when the activating paste is heated. This can be accomplished by heating the fabric or shaped article with the paste thereon to a temperature below the melting point of the polymers used (i.e., to 200 C.), or the paste may be heated prior to application to the article. If the paste includes a dye, both activation and dyeing are accelerated by the heating step. Otherwise, dyeing is carried out subsequent to the treatment, which has the practical advantage than an undyed fabric may be stored and then dyed to any desired two- (or multicolor with natural or pigmented yarns) shade as needed. For the heating step, either steam or dry heat may be used. Steam at about 100 C. for 3 to 20 minutes is, however, preferred for optimum results.
The following examples are included to illustrate but not necessarily to limit our invention.
EXAMPLE 1 A blend of 97.1% isotactic polypropylene and 2.9 percent poly-2-vinylpyridine was melt-spun into fiber, drawn 5:1 and the resultant yarn knit into tubular fabric.
An activating paste was prepared by mixing 100 grams of 90 percent formic acid, 10 grams of hydroxyethylcellulose and 10 grams water. The activating paste was printed on a sample of the tubular fabric in the form of an X. The treated fabric was then heated on a ferrotype plate at 260 F. for 10 minutes, and then rinsed in water containing a small amount of nonionic detergent which is the nonylphenol/ethylene oxide condensate known as Triton X-100. After being scoured at 93 C. for 20 minutes in water at pH 10 containing a small amount of nonionic detergent, the fabric was dyed for 1 hour at 200 F in a dyebath containing 3 percent owf (on the weight of fiber) Capracyl Orange R (Acid Orange 60) and 3 percent owf Calcosperse Yellow 4 RL (Disperse Yellow 23). The fabric was finally post-scoured for 10 minutes at F. in water containing a small amount of nonionic detergent.
The sample was dyed orange where the acid-containing activation paste had been applied and yellow where it had not been applied. The contrast was marked and the borders were clearly defined.
EXAMPLE 2 The procedure of Example 1 was duplicated except that methylcellulose was used as thickener, and spots of paste, rather than an X, were applied to the fabric. After scouring, the fabric was dyed as in Example 1, using only Capracyl Orange R. After dyeing, orange spots resulted where the paste had been applied, while the untreated areas were colored only a very pale pink.
An intimate mixture of 97.1 percent isotactic polypropylene and 2.9 percent poly(2-viny1pyridine) was melt-spun and drawn into a 52-filament 4,000 denier yarn. Three of these yarns were plied together, texturized, and tufted into jute carpet backing. The tufted carpet was then simultaneously activated and dyed using the following procedure:
The face yarn of the carpet was printed with a paste made up of 3 percent Neolan Red BRE (Acid Red 212), 5 percent Lyogen VU (a nonionic alkylphenolpolyether glycol used as levelling agent), 5 percent Polygum 261, a purified natural gum ether thickening agent, 6 percent formic acid and 81 percent water. The carpet containing the paste thereon was put into a saturated steam atmosphere at 212 F. for 20 minutes, removed from the atmosphere and scoured for five minutes at 140 F. with an aqueous solution containing 0.5 percent owf Triton X-100. A carpet having a red pattern printed on it resulted, with good pattern definition of the printed area and negligible migration into and staining of the unprinted area.
EXAMPLE 4 A carpet prepared as in Example 3 was printed with paste containing 3 percent Crocein Scarlet SS (Acid Red 73, C.l. No. 27090), 5 percent Polygum 261, anatural purified gum ether thickening agent, 40 percent of a 1:1 mixture of monochloroand dichloroacetic acid, 7 0.1 percent Triton X-100 and 51.9 percent water. The carpet containing the paste was put into a superheated steam atmosphere at 120 C. for 3% minutes and scoured for 5 minutes with an aqueous solution of 0.5 percent owf Triton X-100 at 140 F. The resultant carpet had a printed scarlet pattern with deep color penetration and negligible dye migration and staining to the untreated areas.
EXAMPLE 5 A carpet prepared as in Example 3 was printed with a paste containing 3 percent Cibalan Grey BL (Acid Black 60), 5 percent Polygum 261, a natural purified gum ether thickener, 40 percent of a 1:1 mixture of monochloroand dichloroacetic acid, 0.1 percent Triton X-100 and 51.9 percent water. The carpet containing the paste was put into a superheated steam atmosphere at 120 C. for 3% minutes. It was then removed from the steam atmosphere and scoured for 5 minutes with an aqueous solution of 0.5 percent owf Triton X-l at 140 F. The resultant carpet had a printed grey pattern with deep color penetration and negligible dye migration and staining to the untreated areas.
EXAMPLE 6 A carpet prepared as in Example 3 was printed with paste containing 3 percent Pilate Fast Blue RRN (an acid metallized anionic dye), percent Polygum 261, a natural purified gum ether thickener, 40 percent of a 1:1 mixture of monochloroand dichloroacetic acid, 0.1% Triton X-100 and 51.9 percent water. The carpet containing the paste was put into a superheated steam atmosphere for 3% minutes at 120 C. It was then removed from the steam atmosphere and scoured for 5 minutes with an aqueous solution of 0.5 percent owf Triton X-l 00 at 140 F. The resultant carpet had a printed blue pattern with deep color penetration and negligible dye migration and staining to the untreated areas.
EXAMPLE 7 A carpet prepared as in Example 3 was printed with a paste containing 2% percent Carbolan Brilliant Blue 2-GS (a strong acid type anionic dye), 2% percent formic acid, 2% percent of an anionic surfactant made from the reaction of fatty alcohols with phosphorus pentoxide, and 92.5 percent water. The printed carpet was heated at 212 F. by steam for minutes in a closed chamber, and then rinsed in water containing 0.5 percent owf nonionic surfactant at 180 F. for minutes. The
resultant carpet was dyed to a deep blue shade in the areas where the dye paste has been applied, and sharp definition of the printed pattern was obtained without staining of adjacent untreated material.
EXAMPLE 8 This example illustrates the technique in the present invention of overprinting with an acid dye on a previously dispersedyed background. For this purpose, a sample of carpet prepared by the same procedure as in Example 3 from a blend of 2.9 percent of the 1:1 copolymer of Z-vinylpyridine. and 2- methyl-S-vinylpyridine with 97.1 percent isotactic polypropylene was dyed with 0.25 percent owf of Terasil Blue GLF (Disperse Blue 27, CI. 60767) in conventional fashion, using 1 percent owf acetic acid in the dye bath and dyeing at the boil for 1 hour. The dyed carpet was then postscoured and dried.
The light blue product was then screen printed with the fol lowing paste formulation:
1 percent Wool Yellow (Acid Yellow 23, CI. 19140) 3 percent Diethanolamine salt of a 1:1 mixture of monoand di-fatty alcohol phosphates 5 percent Formic acid 2.5 percent Polygum 275 88.5 percent water (percentages are on the weight of paste) The printed carpet was steamed for 10 minutes at 105 C. and post-scoured, yielding a green print on a light-blue background. The printed pattern was sharply defined with deep color penetration.
EXAMPLE 9 This example illustrates the technique in the present invention of overprinting with an acid dye on an acid-dyed background. A sample of the carpet used in Example 8 was prescoured and dyed with the following dyebath:
1 percent owf Carbolan Brilliant Blue 268 (Acid Blue 4 percent owf Sodium laurylsulfate 5 percent owf Acetic acid 0.5 percent owf Lyogen MS (a cationic leveling agent for anionic dyes) The carpet was dyed for 1 hour at the boil, rinsed, postscoured and dried. It was medium blue in color.
The dyed carpet was then roller printed with the same paste used in Example 8 and aftertreated in the same fashion as the printed carpet in Example 8. The resultant product had a green pattern on a medium blue background, the pattern being sharply defined and deeply dyed.
EXAMPLE 10 This example illustrates printing with a mixture of Lewis acid and anionic surfactant, followed by dyeing with a mixture of acid and disperse dyes. A sample of the carpet used in Example 8 was screen printed with the following paste:
4 percent Tergitol l5-S-3S 3 percent para-Toluenesulfonic acid 3 percent Polygum 275 90 percent Water The printed carpet was steamed andscoured as in Example 8. It was then dyed in the following dyebath for one hour at the boil:

The printed carpet was steamed for 3 minutes in a superheated steam atmosphere and then postscoured. It had a green pattern of good definition on-a yellow background.
EXAMPLE 12 I A sample of the carpet described in Example 1 1 was dyed to a medium yellow shade with 0.5 percent owf Calcosperse Yellow 4RL (Disperse Yellow 23, C.l. 26070). When printed with the paste described in Example 11, followed by steaming and postscouring as in Example 8, a green pattern on a yellow background was obtained.
EXAMPLE 13 A sample of the carpet described in Example 1 l was printed with a paste containing 40 percent of a 1:1 mixture of monoand dichloroacetic acids, 5 percent Polygum 261 and 55 percent water. The printed carpet was steamed for 3% minutes at 120 C., postscoured and dyed with the dyebath of Example 1. An orange print on a yellow background was obtained. Example 14 A blend of 100 parts of isotactic polypropylene, 3.5 parts of the 1:1 copolymer of 2-vinylpyridine with 2-methyl-5-vinylpyridine and 2 parts of polyethylene glycol of molecular weight 600,000 was converted to carpet yarn by the procedure of Example 3 and tufted into jute carpet backing. Samples of this carpet when treated according to the procedures of Examples 8, 9 and 10 gave results similar to those described in these examples except that the colors were darker.
