Abstract

Kuvaus koskee menetelmää massan alkuperäisvetolujuuden lisäämiseksi, jossa massa on kemiallista massaa ja järjestetty suspensioksi. Menetelmä käsittää massasuspension märkäkalanteroimisen, niin että massan kuidut suoristuvat ainakin osittain ennen massan vedenpoistoa ja/tai kuivaamista; niin että saadaan modifioitua massaa; ja modifioidun massan kuivaamisen, niin että saadaan modifioitua markkinamassaa.
