<p>The procedure provides for the manufacture of crimped high-wet-modulus staple fibres by spinning from viscose to which have been added small quantities of derivatives of cyclohexanone or cyclopentanone and/or alkylated amino compounds of cyclohexane or cyclopentane. To improve the tenacity of the finished fibres, combinations of nitrogen-free and nitrogen-containing modifiers can be used. The viscose and/or spinning bath can also be treated with known stretching and spinning aids. In addition, the crimpyielding additives can be combined with small amounts of zinc ions in the viscose, and the fibres can be allowed to relax in an alkaline bath after being spun. </p> |
