Description

Patented Feb. 17, 1953 ANTISTATIC TEXTILE TREATING COMPOSI- TION F TRIETHANOLAMINE -ALIPHATIC CARBOXYLIC ACID SALTS.
Harry Paul, Coventry, England,
assignor to Courtaulds Limited, London, England, a British company N 0 Drawing. Application December 19, 1949, Se-
rial No. 133,950. In Great Britain January 18,
'7 Claims.
This invention relates to the treatment of artificial staple fibres.
It is well known that certain artificial staple fibres, for example cellulose ester-and E staple fibres, have a tendency to become electrified as a result of rubbing during normal textile operations such as carding, spinning and twisting.
It is known to reduce the tendency of such staple fibres to become electrified during processing by treating them with so-called antistatic compositions and the use of alkylolamines, their soaps or their salts for this purpose has already been proposed. Thus, British specification No. 376,785 describes a process for the treatment of cellulose acetate and the like textile materials comprising applying thereto a preparation consisting of or containing alkylolamines and/or their salts or soaps of aliphatic acids, but containing no fats or fatty oils; in United States patent specifications Nos. 2,067,174 and 2,067,175, the treatment of staple lengths of artificial filaments with like alkylolamine compounds is described. Specific salts or soaps of fatty acids described in the three patent specifications mentioned above are the alkylolamine caprates, laurates, myristates, oleates and stearates. United States patent specification No; 2,081,967 describes the preparation of a lubricating and antistatic finish by emulsifying a mixture of oil, water and such substances of high electrical conductivity as triethanolamine lactate, tartrate, citrate or borate. 4
The object of the present invention is to provide improved antistatic compositions having high conductivity.
In accordance with the'present invention, a method of treating artificial staple fibres to re duce their tendency to become electrified during dispersed an alkylolamine salt of a dibasic acid having the general formula HOOC-(CHz) 11.-COOH 2 l. i;. position contains from ,4; to 2 parts of the alkylolamine-dibasic acid salt for each part. of, the fatty acid saItQparts being by weight. I The antistatic compositions according to the invention may be applied to the staple fibres by spraying, preferably from an atomiser, in a centrifuge, or by immersing the fibres in the composition and then removing excess liquid for example by centrifuging or by passing the fibres through pressure rollers.
The proportion of the alkylolamin-dibasic acid salt, and of the alkylolamine-fatty acid salt when such is also used, in the antistatic composition according to the invention depends generally on the method by which it is applied; the concene tration will normally be selected, so that the treated fibres retain, about to 1 per cent of its weight of the alkylolamine-dibasic acid salt, For example, when using the immersion method of applying the composition to cellulose derivative fibres, the composition may contain from to 1 per cent by weight of the alkylolaminedibasic acid salt, and the fibres, after the im% mersion, may then be pressed or centrifuged till they retain approximately their own weight of solution. When the composition is applied either by spraying or by centrifuging to cellulose derivative fibres concentrations of the alkylolaminedibasic acid salt will in general be higher than 1 per cent by weight, for example from about 2 to'5 per cent.
The materials which may be treated according tothe invention may be any of the staple fibres which are known to be liable to becomeeleotrifie'd during processing such as cellulose'acetate o r other cellulose-ester staple fibres, cellulose" ether staple fibres, casein and other protein staple fibres andnylon staple fibres. The present invention is illustrated by the fol lowing examples in which parts and percentages are by weight.
Example 1 Cellulose acetate staple fibres were immersed in a bath having the following composition:
Part Triethanolamine sebacate Triethanolamine caprate 1 Water The fibres were then removed from the bath 3 a sliver with little or no difficulties arising from static electricity.
Example 2 Cellulose acetate staple fibres were sprayed by means of an atomiser with the following composition:
, Parts Triethanolamine sebacate Triethanolamine caprate -1 2 Water 100 The fibres so treated were readily carded to form a sliver without any marked generation of static electricity.
Example 3 Cellulose acetate staple fibres were treated in a centrifuge with the following composition:
, Parts Triethanolamine suberate 2 Triethanolamine capr'a'te 5 Water 100 lhe treated fibres were readily s'pun into yarns without any marked generation of static electric'i'ty.
What I claim is:

A method of reducing the tendency of artificial staple fibres to become electrified during processing which comprises applying to the fibres an. aqueous composition consistin essentially of (d) water, ('b) a triethanolamine salt of a dibasic acid selected from the group consisting -of adipic acid; pimelic acid, suberic acid, and sebacic acid, and (c) a triethanolamine salt ofatleast one fatty acid the molecule of which contains at least carbon atoms, the composition containing from /2 to 2 parts by weight of the \triethanola'mine-dibasic acid salt (11) for each part by weight of the triethanolamin-e-fatty acid salt (0).
