Tampon production |
摘要 |
A method for the production of a tampon formed of a blend of regenerated solid cellulosic viscose fibres, is provided in which the blend includes a first set of fibres having a first cross-sectional characteristic and a second set of fibres having a second cross-sectional characteristic. The first cross-sectional characteristic is different from the second cross-sectional characteristic. The method includes the improvement of forming the blend by forming a tow of viscose rayon fibres having the same blend ratio of first and second sets of fibres as is required in the tampon by spinning viscose dope through a jet to form a plurality of filaments. The jet has a plurality of dimensionally controlled holes pierced therein. In this way a plurality of different fibre cross-sectional shapes or sizes are simultaneously formed directly in the tow by spinning the viscose dope through the jet having the required plurality of different shaped or sized holes pierced therein.
