Abstract

Polymers and copolymers of acrylonitrile are coloured by incorporating iodides of cationic dyes in the polymer spinning solution. The iodide is dissolved in the same solvent used in the spinning process to give a 5 to 20% or more by weight solution of the dyestuff salt. Clear solutions are obtained which do not clog the spinning nozzles.

Description

SPECIFICATION Mass colouration of poylacrylonitrile using iodides of cationic dyes This invention relates to the mass colouration of polymers or copolymers of acrylonitrile in a preextrusion process where the dyestuff is incorporated in the spinning solution before the spinning process.
The colouration of polymers and copolymers of acryionitrile by incorporating the tetrafluoroborate salts of certain quaternised triazole azo dyestuffs in the spinning solution prior to spinning of the polymer or copolymerfibre has been proposed in British Patent No. 1514263.
We have now found that the iodide salts of a wide range of cationic dyestuffs can be incorporated in the spinning solutions used for the production of fibres of acrylonitrile polymers and copolymers to give coloured polymers of high tinctorial strength having high fastness.
Thus according to the present invention there is provided a process for the spin-dyeing of the polymers and copolymers of acrylonitrile which comprises incorporating into the spinning solution of the polymer or copolymer an iodide salt of a cationic dyestuff.
The process of the invention is applicable to the wide variety of polymers and copolymers of acrylonitrile. It may be applied for example to homopolymers of acrylonitrile and to copolymers thereof with other vinyl compounds for example vinyl chloride, vinyl acetate and acrylic and methacrylic esters and amides. Polymers and copolymers of acrylonitrile available as articles of commerce corltain acid groups which are essential for the attachment of basic dyestuff molecules to the polymer or copolymer.
It will be realised that the presence of acid groups in the polymers or copolymers of acrylonitrile is essential for the application of the present process.
There my be used in the present process any of the iodide salts of the many known classes of cationic dyestuffs or basic dyestuffs as thay are often called. Thus there may be used the iodide salts of cationic or basic dystuffs of the azo, anthraquinone, methine, styryl, naphtholactam, oxazine, thiazine, triphenylmethane, coomarin, quinophthalone and nitro series. The process is particularly useful with iodides of cationic monoazo dyestuffs of the carbocyclic and heterocyclic series for example azobenzene derivatives, azopyridones, diazahemicyanines and diazacarbocyanines and also with odides of hemicyanines, azacarbocyanines and triazacarbocyanines.
The foilowing classes of dyestuffs are given as more specific examples of cationic dyestuff types which may be used in the present process, the formula of specific dyestuffs in each class are given by way of exemplification.
Azobenzenes from para-eounling aminesZ for example
Azole,yridones, for example
Hemicyanines, for example
Diazahemieyanine, for example
Azacarbocyanines, for example
Diazacarbocyanines, for example
Anthraguizone, for example
Triphenylmethane. for example
Malachite Green Iodide Oxazine, for example
Thiamine, for example
r# Methylene Blue Iodide Triazacarbocyanine, for example
Naphthostyrols (Naphtholactams), for example
Coomarin, for example
lodide salts of cationic dyestuffs may be made by normal double decomposition reaction. For example the dyestuff of formula
may be dissolved in 5% aqueous acetic acid by warming to 400 C, the solution screened from trace insoluble matter by filtration with a filter aid and the filtrate treated with 20% aqueous sodium iodide to precipitate the dyestuff iodide salt which can be recovered by filtration.
The process of the invention may be carried out by dissolving the dyestuff iodide salt in the same solvent as is used in the spinning process for dissolution of iihe acrylonitrile polymer or copolymer, for example dimethyl formamide, dimethylacetamide or dimethylsulphoxide and then adding this solution of dyestuff iodide salt to the spinning solution. The mixture is then adequately mixed and the polymer or copolymer spun in the normal way, for example by a dry spinning process or by a wet spinning process.
The spun fibres may be given any of the after-treatments known in the art.
The solution of the dyestuff iodide salt is preferably a concentrated solution containing for example 5% to 20% by weight or more of the dyestuff salt. The dyestuff iodides possess high solubility in the solvents normally used in spinning processes.
We have found that by use of the iodide salts it is possible to obtain clear spinning solutions which do not clog the spinning nozzles. The dyed fibres produced by the process of the invention have high fastness to wet treatments and good light fastness.
The physical properties of the fibres were not impaired by the process of colouration.
