Abstract

The precipitation-bath used for the spinning of artificial threads, bands, films, &c., from viscose contains the sulphonic acids of mineral oils, aliphatic tars or tar oils, or the condensation products of these sulphonic acids with aldehydes, ketones, etc.; of the substances specified, those that coagulate glue are particularly suitable. The sulphonic acids may be in part in the form of salts. The baths may also contain mineral acids, salts, natural tanning substances, &c. In examples, the baths contain the products obtained by sulphonating brown coal tar or machine oil with concentrated sulphuric acid at room temperature, or the condensation products of these sulphonic acids with formaldehyde. Specification 234,188 is referred to.ALSO:Sulphonic acids of mineral oils, or of aliphatic tars or tar oils, such as brown coal tar oil or machine oil, are obtained by treating these oils &c. with concentrated sulphuric acid at room temperature. The sulphonic acids may be condensed with formaldehyde or other aldehydes, ketones, &c. in the known manner. Specification 234,188 is referred to.
