Title: Process for reducing the readiness with which synthetic fibres accept an electric charge
IPC: D06M13/405
Filed: 1962-11-01
Abstract: Salts derived from C1-5 monocarboxylic acids and amino-amides of the formula <FORM:0971527/C1/1> where R represents a C11- 17 linear aliphatic hydrocarbon residue, R1 and R2 are methyl or ethyl, and m is 1 or 2, are prepared by neutralizing the amino-amide with, for example, acetic, propionic or formic acid.  One mole of an amino-amide of the above formula may be quaternated with one mole of halogenoacetic acid to give a compound of the formula <FORM:0971527/C1/2> where X is a halogen atom and R, R1, R2, and m are as defined above.  If two moles of amino-amide are reacted with one mole of halogenoacetic acid the corresponding amido-amine salt of the above acid is formed.ALSO:Compositions for reducing the readiness with which synthetic fibres accept an electrostatic charge comprise (a) a mineral oil; (b) one or more salts derived on one hand from organic monocarboxylic acids and on the other hand from bases of the formula <FORM:0971527/C4-C5/1> in which R stands for a C11-17 linear aliphatic hydrocarbon residue, R1 and R2 are methyl or ethyl, and m is 1 or 2; and (c) one or more bases of the formula <FORM:0971527/C4-C5/2> in which R1 stands for a C11-17 linear aliphatic hydrocarbon residue having at least one double bond, R3 and R4 are methyl or ethyl and m is 1 or 2; where the ratio of (c) to (b) is from 1: 10 to 20: 10.  The monocarboxylic acids used in making the salts (b) may be C1-5 aliphatic monocarboxylic acids, e.g. propionic, acetic or formic, or an acid of the formula <FORM:0971527/C4-C5/3> where X is a halogen atom and other symbols are as defined under (b). The additives (b) and (c) are exemplified, and the compositions are suitable for emulsification in water.ALSO:Compositions for reducing the readiness with which synthetic fibres accept an electrostatic charge comprise (a) a mineral oil, (b) one or more salts derived on one hand from organic mono-carboxylic acids and on the other hand from bases of the formula <FORM:0971527/D1-D2/1> in which R stands for a C11-17 linear aliphatic hydrocarbon residue, R1 and R2 are methyl or ethyl, and m is 1 or 2, and (c) one or more bases of the formula <FORM:0971527/D1-D2/2> in which R1 stands for a C11-17 linear aliphatic hydrocarbon residue having at least one double bond, R3 and R4 are methyl or ethyl and m is 1 or 2, where the ratio of (c) to (b) is from 1 : 10 to 20 : 10.  The monocarboxylic acids used in making the salts (b) may be C1-5 aliphatic monocarboxylic acids, e.g. propionic, acetic, or formic, or an acid of the formula <FORM:0971527/D1-D2/3> where x is a halogen atom and other symbols are as defined under (b).  The additives (b) and (c) are exemplified, and the compositions are suitable for emulsification in water. Textiles which may be treated with the compositions include cellulose esters, polyesters, polyamides, polyurethanes, polyacrylonitrile, fibres formed from copolymers or mixtures of these materials, fibre blends of different synthetic fibres, and mixtures of synthetic and natural fibres of animal or vegetable origin.
