HANS LEEIANN, OE BOTTMINGERMUHLE-BINNINGEN, NEAR BASEL, AND GIOVANNI TAGLIANI, OF BASEL. SWITZERLAND, 'ASSIGNQRS. BY MESNE ASSIGNMENTS, TO MUNITEX CORPORATION, OF LODI, NEW JERSEY, A CORPORATION OF NEW JERSEY.
RESERVE DYEING N VEGETABLE FIBERS.
ll'o Drawing Original application filed April 27, 1925, Serial No. 26,289, and'in Germany May 7, 1924. Divided and this application filed May 20, 1926. Serial No. 110,540.
This application is divisional of application Ser. No. 26,289.
The hitherto known reserve processes consist of mechanical or chemical operations. I To the first typebelcngs'the binding and the covering ofthe vegetable fibers (yarns and fabrics) by substances insoluble in water so. that the dyestufisemployed can only soak in and be fixed on the unbound or uncovered arts of the fabric. To the second class beon the application of certain agents, prefera 1 of salts, which react chemically during t e dyeing or during the developmentof the dyes. All these rocesses depend, however, on certain con itions. If the reserve agents employed are removed during the dyeing process or during the development of the dyes, or if they do not resist these operations until the end of the dyeing, then the so desired reserve effect does not occur and the fabric is dyed uniformly throughout as if the reserving a nts had not been used at all. It is known bm German specificatlon No. 346,883 and others, that it is possible to render vegetable fibers (yarns, loose material,
fabrics) completely immune agalnst substantive dyestuffs by treating them after alkalinization with solutions of aromatic carboxylic acid chlorides or aromatic sulpho so acid chlorides. Both the alkalinization. and
the action of the aromatic acid or 'sulpho acid chlorides are so effected that the .whole of the vegetable fibers is brought into the solutions of the respective agents.
It has now been shown in a surprising manner that this esterification can also be used for the topical alteration of the vegetable fibers, in viewof the pi'oduction of reserve effects, for example in a suitable print-.
40 ing process. It was not at al lto be foreseen from the more active treatment insolution that the short superficial and sparing local treatment, as it takes place for example in the printing process, would suflice to pro- 46 duce the desired esterification. This process affords permanentlyreserving patterns with unexpected dyeing pro erties, which remain fast even after hot was ing 0 eratlons, after hot neutral, acid or alkaline ye baths.
50 The roduction of such reserve efiects is now utilized in the process for reserve dyeing on vegetable fibers forming the subject of the present invention. This process consists in first treating topically the vegetable fibers by a local printing with a suitable alkalizing agent, such for example as a concentrated alkaline solution, with or without thickening agent, with or without the addition of alcohol, with or without an alcoholic solution of an alkali alcoholate, then in applying thereon in dry or moist condition, an esteri ying aromatic acid chloride such as an aromatic carboxylic acid chloride, or an aromatic sulpho acid chloride, in pure or dissolved condition, and finally after the resulting esterification in thoroughly washing the vegetable fibers being thus locally altered at the places of the aforesaid print, to constitute what is commonly termed as reserve efiects. Thereupon the fibers are dyed with a substantive dyestufi, without the locally altered esterified places taking up the dye,
so that they appear white on a coloredground. However, it has been found that saltspf diazotable bases can be fixed by the esterified places of the locally altered vegetable fibers, whereupon they can be developed by suitable developing means,
The fibers may be in form of loose material, yarns or fabrics. As dyestufis,--there may be used the usual coloring matters which are suitable for carrying out the improved process.
What we claim is:
1. A process for reserve dyeing on Vegetable-fibers, which consists intreating topically the vegetable fibers by a local printing with an alkalizing agent, thereupon applying an esterifying aromatic acid chloride to produce a topical alteration of the locall printed fiber, thus constituting reserve efi fects, then washing after the esterification, and thereupon treating the thus topically altered fibers first with a salt of a diazotable base and then after diazotizing with developing means. 2
2..A' process for reserve dyeing on vegetable fibers, which consists in treating topically the vegetable fibers] by a local print ing with an alkalizing agent, thereu on applying an esterifying aromatic sulp 0 acid chloride, to produce a topical alteration of the locall printed fiber, thus constituting reserve e ects, then washlng after the esterification, and thereupon treating the thus topically altered fibers first with a salt ofa determined areas of said fibers with an alkalizing agent, esterifying said treated areas with an aromatic sulpho acid chloride whereby reserve effects are produced, washing said fibers and treating said areas first with a salt of a diazotable base and then after diazotizing with developing means.
In witness whereof we have hereunto signed our names this 10th day of May, 1926.
