The role of xylan and glucomannan in yellowing of kraft pulps
, 1995 The effects of xylan and glucomannan on the thermal stability of unbleached, partially bleached, and fully bleached pine and birch kraft pulps were studied. The choice of bleaching chems. strongly affected the brightness reversion.

Effect of particle size on the surface properties and morphology of ground flax [PDF]
, 2013 Flax fibers were ground with a ball-mill and four fractions with different size ranges were collected by sieving. These were tested for water sorption, degree of polymerization (DP), copper number, hydroxyl number and analyzed by X-ray diffraction (XRD),
