The cellulose is dissolved in caustic soda and left to age for a couple of days. From there, carbon sulfide is added to the mix to create xanthate, a pulpy, yellowish substance. Xanthate is then forced through tiny holes (spinnerets), with the resulting products dropping directly into a sulfuric acid bath that solidifies them into fibers. Lastly, those fibers are spun into threads or yarns, which can be dyed or further treated to fit different applications.
