2. Application and procedure of Optical Brightening Agent KB 199
It is mainly used for whitening and brightening polyster fiber,
especially polyster staple fiber and polyster fabric. At the same
time, it is especially suitable for whitening various kinds of
plastic products, cellulose acetate fiber, polypropylene fiber etc.
Before drawing fiber, remove the sundries in polyster chips( or
plastic substrates); weigh the materials and add them to the
melting tank. Raise the temperature to 120-130°C; Vacuumize the
tank to remove the moisture contained in materials; Stop
vacuumizing add KB-199 whitening powder to the chips according to
150-300g/tons; fully mixt them, so that the dry powder could be
