English

Subject field(s)
  • Pulp Preparation (papermaking)
DEF

A brightening treatment with hydrosulphite or peroxide in which the lignin and carbohydrates are not degraded, thus preserving the yield advantage of the pulping process. It is usually referred to as brightening to distinguish it from lignin-removing processes.

French

Domaine(s)
  • Préparation de la pâte à papier
DEF

Traitement de blanchiment avec l'hydrosulfite ou le peroxyde au cours duquel la lignine et les hydrates de carbone ne sont pas dégradés.
