Definitions
- the invention relates to a process for thefmanufacture of high bulk textile materials of polyacrylonitrile by heat treatment of textile materials consisting of polyacrylonitrile by heat treatmentbf textile materials consisting of nitrile fibre materials of different thermal shrinkability; the process is characterised in that the heat treatment is carried out in chlorinated hydrocarbons which optionally contain small amounts of water and small amounts of emulsifiers.
- Processes are already known'for bulking textile materials consisting of polyacrylonitrile fibre materials of different thermal-:shrinkability by treatment with boiling water-or steam.
- the process according to the invention is distinguishedjfrom these known processes in that it yields high bulk materials which in handle, appearance and degree of cleanliness are superior to the high bulk textile materials manufactured according to the known processes,
- the main advantage of the process accordingvto'the invention however resides -in;the fact that the textile materials can be dyed from the same treatment bath immediately after the 15 bulking process.
- the process according to the invention therefore represents a single-bath process for the bulking and dyeing of polyacrylonitrile fibre materials of different thermal shrink-ability.
- Possibile chlorinated hydrocarbons for the process according to the invention are especially the chlorinated hydrocarbons with boiling points lyingbetween 85 and 150 C., for example especially aliphatic'fchlorinated hydrocarbons, such as l,1,l,2-tetrachlorethane, 1,1,2,2 -tetrachlorethane, 1,l-dichloropropane,; 1,2-dichloropropane, ..-1,3-dichloropropane, 1,1,1-trichloropropane,: l-chlorobutane, 2- chlorobutane, 1-chloro-2-, methylpropane or 2 -.chloro-2- methylpropane and l,1,1-trifluoropentachloropropane, but also aromatic hydrocarbons, such as chlorobenzene.
- aromatic hydrocarbons such as chlorobenzene.
- vTetrachlorethylene and trichlorethylene have proved particu- 3,679,354 Patented July 25, 1972 ice monium compounds possessing two hydrocarbon radicals with a total of at least 32 carbon atoms, such as N,N-dihexadecyl N,N dimethylammonium chloride, N-hexadecyl N oleyl N,N dimethylammonium methylsulphate and N,N dihexadecyl N benzyl N methylammonium chloride; also, fatty acid ethanolamides and ethoxylation and/or propoxylation products of fatty alcohols, fatty amines, fatty acids, fatty acid amides, alkylphenols, aralkylphenols and 'arylphenols as well as their mixtures with one another.
- the emulsifiers are advantageously employed in an amount of 0.01-0.5 percent by weight relative to the weight of the chlorinated hydrocarbons.
- chlorinated hydrocarbons additionally to the small amounts of water and emulsifiers, also small amounts, say 0.005-1 percent by weight, relative to the weight of the chlorinated hydrocarbons, of lower aliphatic carboxylic acids such as formic acid or acetic acid.
- polyacrylonitrile fibre materials of difierent thermal shrinkability-to be bulked according to the process of the invention can be mixtures of fibre materials of different thermal shrinkability or bi-component fibres or bi-component filaments.
- the dilferent thermal shrinkability can be based on a diiferent thermal or thermal-mechanical pretreatment of the fibre materials or on a different modification of the polyacrylonitrile by various comonomers.
- the polyacrylonitrile fibre materials to be bulked according to the invention can have been dyed with optical briglitene'rsr
- cationic dyestuffs can be used.
- These can be-1used-in'the form of salts, which are soluble in the chlorinated hydrocarbon, of dyestufl cations and anions of aliphatic or aromatic carboxyli-c, sulphonic or phosphonic acids possessing 4-30 carbon atoms, or in the form of water-soluble salts of dyestufi cations and anions of inorganic acids.
- These water-soluble salts are emulsified in the chlorinated hydrocarbon b'aths in the form of aqueous solutions.
- cationic dyestuffs there may-for example be mentioned: methine, azomethine, hydrazone or azacyanine dyestufis, dyestufis'of the diarylmethane or triarylmethane series, xanthene, thioxanthene, acridine, oxazine, thiazine and phenagine dyestufi's as, well.
- anions for the water-soluble .dyestulf salts are above all theanions of inorganieacids, for example halide ions, such asthe chloride, bromideor iodide ion, also.. the nitrate, perchloratemnd bisulp hatev ion, and the anions which are derived from the sulphuric acid esters andv sulphonic acids, such as the methylsulphate,ethylsulphate and toluenesnlphonateion.
- halide ions such asthe chloride, bromideor iodide ion, also.. the nitrate, perchloratemnd bisulp hatev ion
- Possible anions for the salts which are solublein the chlorinated hydrocarbons are for example: the 2-ethylcaproate, laurate, oleate, linoleate, nonylphenol-tetraethyleneglycol-ether-propionate, 3 '--'-nonylphenoxy)-propionate, nonyl-phenoxyacetate, tert.-butylbenzoate, hexahydrobenzoate, abietate, dodecylbenzenesulphonate and tetrapropylenebenzenesulphonate ion.
- the amounts in which the dyestufis optionally to be used are present in the dyebath can vary within wide limits 1 depending on the desired depth of colour: 0.1-5 percent by weight of dyestulf, relativeto the weight of the fibre material, have proved successful.
- the process according to the invention is for example carried out in such a way that the fibre material to be bulked, which can be in the form of yarn, woven fabric or knitted fabric or a made-up article manufactured therefrom, is treated for 5-60 minutes at 90-125" C. in a closed apparatus, for example a paddle apparatus or a drum dyeing apparatus, using a liquor ratio of 1:10-1:50, in the chlorinated hydrocarbons which optionally further contain small amounts of water, emulsifier and lower aliphatic carboxylic acids, such as formic or acetic acid. Following the bulking, the material is optionally dyed in the same bath by cooling the treatment bath to 80 C.
- EXAMPLE 2 100 parts of yarn of polyacrylonitrile fibres of difierent thermal shrinkability (60% thermally shrunk+40%. unshrunk polyacrylonitrile fibres) in bank form are treated for 45 minutes at 95 C. in 1989 parts of perchlorethylene in a closed apparatus. Thereafter the bath is cooled to 80 C. and after addition of 11 parts of a dyestuff preparation consisting of: i g
