Definitions
- One modification which is frequently employed consists in using substances which facilitate the production of the viscose, for example, at the time of xanthation, by shortening the time required for xanthate formation by emulsifying the carbon disulphide and/ or dispersing impurities in extremely fine form in the viscose, so that, for example, satisfactory filtration is guaranteed.
- An improvement in the filament-drawing capacity is apparent with these additives.
- the disadvantageous deposition of impurities from the viscose and/or from the spinning bath at the spinnerets is avoided. On account of the products added to the spinning baths or products reaching the baths from the viscose, the said baths remain free from clouding substances which otherwise usually sediment.
- amine oxides of the general formula cording to the invention are, for example dimethyl lauryl, diethyloctyl, tributyl, dimethyl butyl, triisopropyl, triiso- 3,114,592 Patented Dec. 17, 1963 octyl, methoxyethylmethyl lauryl, dimethyl stearyl, diethyl oleyl, dimethyl cyclohexyl, dicyclohexyl methyl and dimethyl phenyl amine oxides.
- Example 0.2 g. of dimethyl laurylamine oxide are added per litre to a viscose normally used for the production of textile filaments.
- the eflfect of the additive is that the viscose becomes completely transparent, can easily be filtered and shows excellent filament-drawing capacity. Its surface tension is also reduced by at least 50% and, on spinning into a conventional Miiller bath, it does not cause any incrustation of the spinnerets. Impurities in the precipitation bath are also avoided.
- Example 2 If an unripe viscose is processed, as in Example 1, using 0.8 g./l. of diethyloctylamine oxide, the effects mentioned in Example 1 are also produced. In addition, the milkiness which always occurs when processing unripe viscose is avoided.
- Example 3 0.5 g./l. of dimethyl laurylamine oxide are added to a normal viscose to which a matting agent or a spinning dye-stuff has been added.
- the amine oxide can also be added by first of all being mixed with the pigment, the mixture then being incorporated in the viscose. If this viscose is spun in the usual manner, more intensive matting or dyeing effects are produced than those obtained when amine oxide is not used. It is obvious that the amine oxide produces an improved dispersion of the pigment in the viscose, whereby a better utilisation of the pigment is obtained.
- Example 4 If 2 g./l. of tributylamine oxide are added to a viscose normally used for the production of cord filaments, the stretchability is improved to a surprising degree and thereby a cord rayon with a high strength value is produced.
- amine oxide selected from the group consisting of Dimethyl laurylamine oxide
- Dimethyl cyclohexylamine oxide Dicyclohexyl methylamine oxide, and Dimethyl phenylamine oxide.
- a process for the production of spun hydrated cellulose which comprises the steps of adding to viscose 0.2 g./l. referred to the viscose of an amine oxide of the formula Ra wherein R R R are selected from the group consisting of alkyl, cycloalkyl, alkoxyalkyl, and phenyl, the sum of the C atoms of the R substituents being from 6 to 24, introducing the viscose through spinnerets into a spinning bath and recovering the spun hydrated cellulose therefrom.
