Abstract
Disturbing substances such as calcium ion and non-ionic starch were fo und to be detrimental to the performance of wet end chemicals. By usin g a new generation of cationic starch in conjunction with an anionic c olloidal silica, these detrimental effects were minimised. Results of both laboratory work and full scale machine trial are presented. A the ory to explain the mechanism of these starches is also proposed.
