    • A method for the production of a tampon (32) formed of a blend of regenerated solid cellulosic viscose fibres, said blend including a first set of fibres having a first cross-sectional characteristic and a second set of fibres having a second cross-sectional characteristic, said first cross-sectional characteristic being different to said second cross-sectional characteristic which includes the improvement of forming said 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 jet means (7) to form a plurality of filaments (9), the jet means having 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 a tow (10A) by spinning the viscose dope through the jet means having the required plurality of different shaped or sized holes pierced therein.
    • 一种用于生产由再生固体纤维素粘胶纤维的共混物形成的止血塞(32)的方法,所述共混物包括具有第一横截面特征的第一组纤维和具有第二横截面特征的第二组纤维 所述第一横截面特征与所述第二截面特性不同,包括改进形成所述共混物,通过形成具有与棉塞中所需的第一和第二组纤维相同的混合比例的粘胶人造纤维丝束 通过通过喷射装置(7)纺丝粘胶剂以形成多根长丝(9),该喷射装置具有在其中刺穿的多个尺寸控制的孔。 以这种方式,多个不同的纤维横截面形状或尺寸通过使具有所需的多个不同形状或尺寸的孔在其中穿透的喷射装置纺丝而在丝束(10A)中直接同时形成。
