Title: Improvements in or relating to assistants used in the treatment of textiles and other fibrous materials
Filed: 1933-11-24
Abstract: The true sulphonic acids, prepared according to Specification 424,891 from tertiary alcohols containing at least one aliphatic or cycloaliphatic residue with at least eight carbon atoms or their salts are used as assistants in processes for wetting, cleansing, washing, dyeing, finishing and oiling fibrous materials such as textiles, fur and leather.  The true sulphonic acids of olefines obtained from the said tertiary alcohols by removal of water may be used in the same processes.  The tertiary alcohols obtained according to Specifications 422,804 and 423,880 may be used as starting material.  In examples: (1) the sodium salts of sulphonic acids of the carbinols derived from soya fatty acids and containing two ethyl groups attached to the carbinol carbon are used as levelling agents in dyeing wool with acid wool dyes; (2) the sodium salts of the sulphonic acids of the carbinols derived from whale oil fatty acids and containing two methyl groups attached to the carbinol carbon are used in dyeing viscose silk materials such as stockings; (3) the sodium salts of the sulphonic acids of the carbinols derived from soya fatty acids and containing two methyl groups attached to the carbinol carbon are used in mercerizing and bucking lyes; (4) the sodium salts of the sulphonic acids of the carbinols derived from linseed oil fatty acids and containing two ethyl groups attached to the carbinol carbon are used in a washing process; frothing is avoided when automatic washing machines are used; (5) the sodium salts of the sulphonic acids of the carbinols derived from sperm oil fatty acids and containing two methyl groups attached to the carbinol carbon are employed in sizes and finishes; (6) the triethanolamine salts of the sulphonic acids of the carbinols derived from coconut fatty acids and containing two methyl groups attached to the carbinol carbon are used in the manufacture of emulsions for use as yarn lubricants in spinning and as leather polishes.  The sulphonic acids may be prepared by sulphonating with sulphuric acids and acetic anhydride the carbinols obtained by reacting the oils with methyl or ethyl magnesium bromide or chloride.  The sulphonic acids may be used in association with perborates, persulphates, percarbonates, soda, trisodiumphosphate, waterglass, borax, sodium sulphate, acids such as acid sodium sulphate, superfatting agents, solvents such as alcohols, enzymes such as urease and pancreatin, and other wetting, washing, bleaching, cleansing, emulsifying and dispersing agents.ALSO:The true sulphonic acids, prepared according to Specification 424,891, [Group IV], from tertiary alcohols containing at least one aliphatic or cycloaliphatic residue with at least eight carbon atoms, or their salts are used in the production of detergents, yarn lubricant emulsions for spinning, and polishes for leather.  The true sulphonic acids of olefines obtained from the said tertiary alcohols by removal of water may be used in the same processes.  The tertiary alcohols obtained according to Specifications 422,804 and 423,880, [both in Group IV], and the following carbinols may be used as starting materials; the carbinols derived from soya fatty acids and containing two methyl or ethyl groups attached to the carbinol carbon, the carbinols derived from whale oil fatty acids and containing two methyl groups attached to the carbinol carbon, the carbinols derived from linseed oil fatty acids and containing two ethyl groups attached to the carbinol carbon, the carbinols derived from sperm oil fatty acids and containing two methyl groups attached to the carbinol carbon, and the carbinols derived from coconut fatty acids and containing two methyl groups attached to the carbinol carbon.  The sulphonic acids or their salts may be used in association with perborates, persulphates, percarbonates, soda, trisodiumphosphate, waterglass, borax, sodium sulphate, acids such as acid sodium sulphate, superfatting agents, solvents such as alcohols, enzymes such as urease and pancreatin and other wetting, washing, bleaching, cleansing, emulsifying and dispersing agents.
