Abstract

Viscose silk, &c. of five deniers or even less is made by spinning into a relatively-dilute acid-salt bath containing 4-10 per cent of a zinc salt, for example, zinc sulphate. A suitable bath contains from 18-32 per cent of sodium sulphate or other salts such as ammonium, magnesium or other sulphate, preferably from 20-28 per cent of these salts; and 9-13 per cent of sulphuric acid; and it is convenient to work with such a bath at a temperature of 40-45 DEG C. After leaving the bath the filaments may be treated in the funnel leading to the centrifugal box, with a solution of similar composition to that of the precipitating-bath but of lower concentration, or with a solution not containing a zinc salt, or with water alone. Specification 215,028 is referred to.
