| titleOfInvention | Improvements in dyeing and printing vegetable or artificial textile materials |
| abstract | Substantive dyes, dyeing with; regenerated celluloses, dyeing; printing.--Vegetable or artificial textile materials or mixed fabrics containing different vegetable or artificial textile materials are dyed or printed with non-basic dyestuffs containing one or more sulphonic and/or carboxylic groups in the presence of an organic compound free from sulphonic groups and containing in the molecule at least one radicle with at least six carbon atoms and at least one basic reacting atom of pentavalent phosphorus, arsenic or antimony or tetravalent sulphur, such compound being capable of forming a salt with the dyestuff. Such compounds may be used in a pretreatment liquor or incorporated in the dyebath or printing paste. Specified compounds are trimethylmyristylphosphonium hydroxide, dimethylethyloleylphosphonium chloride, triethyldodecylphosphonium bromide, trimethyldodecylarsonium hydroxide, dimethylethylcetylarsonium chloride, trimethylundecylstibonium chloride, dimethylcetylsulphonium hydroxide and methylethyloctodecylsulphonium chloride. The dyebath or printing paste may also contain dispersing agents or protective colloids such as sulphuric esters of high molecular aliphatic alcohols, high molecular aliphatic sulphonic acids, sulphonated mineral oils, condensation products of high molecular carboxylic acids with hydroxyalkyl- or aminoalkyl-sulphonic acids or albumen degradation products and salts thereof, sulphite cellulose waste liquor, the reaction products from hydroxy, amino or carboxylic compounds and an alkylene oxide in excess, glue, gum arabic or gelatine. The following examples are specified: (1) Cotton yarn is treated for 1 hour with a solution at 80 DEG C. of triethyldodecylphosphonium bromide, centrifuged, dried and woven or otherwise worked up with viscose artificial silk and the product is dyed in the usual manner by treatment for 1 hour in a bath at 90 DEG C. containing Sirius red 4B and Glauber's salt; (2) A mixed fabric of cotton and viscose artificial silk is treated for 1 hour with a solution at 90 DEG C. of the methylsulphuric acid salt of methylethylcetylsulphonium hydroxide or triethyldodecylphosphonium bromide, centrifuged and dyed in the usual manner by treatment for 1 hour in a bath at 90 DEG C. containing Triazole dark blue BH and Glauber's salt; (3) Viscose artificial silk hosiery is dyed by treatment for 1 hour in a bath containing Direct deep black EW extra, triethyldodecylphosphonium bromide, the reaction product from ethylene oxide (20 mols.) and oleyl alcohol (1 mol.), and Glauber's salt. Specification 281,473, [Class 15 (ii)], is referred to. Trimethylmyristylphosphonium hydroxide is obtained by reacting trimethylphosphine with myristyl iodide and converting the iodide into the hydroxide. Dimethylethyloleylphosphonium chloride is obtained by reacting dimethylethylphosphine with oleyl chloride. Triethyldodecylphosphonium bromide is obtained by reacting triethylphosphine with dodecyl bromide. Trimethyldodecylarsonium hydroxide is obtained by reacting trimethylarsine with dodecyl iodide and converting the iodide into the hydroxide. Dimethylethylcetylarsonium chloride is obtained by reacting dimethylethylarsine with cetyl chloride. Trimethylundecylstibonium chloride is obtained by reacting trimethylstibine with undecyl chloride. Dimethylcetylsulphonium hydroxide is obtained by reacting dimethyl thioether with cetyl iodide and converting the iodide into the hydroxide. Methylethyloctodecylsulphonium chloride is obtained by reacting methylethyl thioether with octodecyl chloride. Methylethylcetylsulphonium hydroxide is obtained by reacting methylethyl thioether with cetyl bromide and treating the product with moist silver oxide. |
