We have studied diffuse reflectance in the spectral range λ = 380–760 nm of sulfate cellulose pulp with initial hardness G = 30–70 after it was treated with a chlorine-containing bleaching agent with active chlorine concentration C = 0%–10% for different time intervals. We determined the...
All fluff pulp is bleached in order to achieve maximum absorbency andthebleachingprocess is Elementary Chlorine Free (ECF), consequently no chlorine gas is used. tena.com tena.com 所有绒毛浆均经过漂白程序,以达到最佳吸收力的效果,漂白程序采用无氯漂白法(ECF),因此全程未使用氯气。

The pulp underwent alkaline extraction, followed by a two-stage bleaching process consisting of chlorine dioxide (ClO2) treatment and catalytic hydrogen peroxide (H2O2) bleaching with CuSO4 as an activator. The resulting alpha-cellulose samples were characterized using various analytical techniques, ...
