Description

The invention relates to a process for the preparation of anhydrous formulations for lubricating artificial fibers with the use of mineral oil, oleic acid, triethanolamine and glycerin.

In accordance with the present invention, in order to obtain persistent fat blends, which are well emulsified in water, it is proposed to heat the mixture consisting of these substances with vigorous stirring to a temperature not exceeding 60 ° until the foam disappears.

From the recipes developed by the authors, the best results were given by the following.

Ip

(in o / o) (in

Perfume or transformer oil. . 74.6 80.0 Oleic acid. . . 19.2 14.0

Triethanolamine6.2 6.0

In both cases, if desired, an antioxidant can be administered in an amount of 1%, for example, p-naphthol.

In view of the fact that these lubricants (the second differs from the first in that it is less greasy and more deciduous) are anhydrous, the fiber at

their application does not lose its mechanical strength and the dynamometric parameters remain unchanged.

From the above components can be prepared a large number of lubricants with positive properties. Fluctuations in the constituent parts can be allowed within the following limits: 1) mineral oils (transformer, perfume, petroleum jelly) from 1 to 7%; 2) fatty oils and acids from 1 to 6%; 3) emulsifiers from 1 to 37 ° C But by experimental selection, lubricants with continuous oscillations can be compiled.

The proposed lubricants are prepared as follows. Mineral oils (perfume, vaseline or transformer), kept at room temperature for 1-2 days, are mixed with liquid oleic acid. Triethanolamine is then added and the whole mass is carefully moved until it is yellow. The next component is added lightly mobile alizarin oil and

the whole mass is again vigorously stirred until uniform. The last is glycerin. The mass with constant stirring is heated to 60-60 ° and this temperature is maintained for 2 hours until the foam disappears.

Distinctive qualities of the proposed sizing:

1. The proposed lubricants do not exfoliate either in a concentrated form or in aqueous emulsions for a very long time (about a year for concentrates).

2.Gasters give good stable water emulsions.

- 3. Emulsifier triethanolamine, which, unlike emulsifiers used previously (caustic soda, caustic potassium, ammonia), forms with the fatty acids soluble in mineral oils of soap is introduced into the lubricants.

4. All Oils in a concentrated form are anhydrous.

5. The dispensers applied to the fiber are easily washed away, so that there is no neprokras and unevenness of paint in the edge processes of the finished product, which is almost always the case when using other emulsions.

6. The dispensers are difficult to oxidize, which guarantees the lack of variegation in silk after the drying processes, and therefore, the lack of variability in dyeing.

7.Gasters have almost no smell. Silk, processed by them, also has no smell.

8. The effect attributed to silk by sizing, as observations have shown, is maintained for at least 6 months. During this time, no change in silk color was detected.

9. The offered Lubricants dissolve well in solvents such as kerosene, naphtha, white spirit, while retaining the qualities of a good emulsifying ability in water.

The subject matter of the invention.

A method for preparing anhydrous formulations for lubricating artificial fiber using mineral oil, oleic acid, triethanolamine and glycerin, characterized in that, in order to obtain stable fat mixtures that are well emulsified in water, the mixture consisting of these substances is heated with vigorous stirring not more than 60 ° until the foam disappears.
