Zusammenfassung:	PCT No. PCT/SE79/00235 Sec. 371 Date Jul. 14, 1980 Sec. 102(e) Date Jul. 9, 1980 PCT Filed Nov. 14, 1979 PCT Pub. No. WO80/00979 PCT Pub. Date May 15, 1980.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 crimp-yielding 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.
