Abstract

When spinning from viscose hollow fibres of 2 deniers or less, particularly staple fibres, while employing the coagulating baths described in Specification 255,527, [Class 2 (ii)], the temperature of the bath is increased in a manner inversely proportional to the desired elementary titre, the minimum value of the temperature being given by the expression (a--bd), where a = 70-75, b = 9-11, and d = desired elementary titre. As a modification, the temperature is raised to a smaller extent in conjunction with a variation of the concentration of the bath according to Specification 426,905, but not to the full extent prescribed by that Specification. Specification 421,157 also is referred to.
