Abstract
resumo celulose modificada de superfície tratada a partir de fibras químicas de kraft e métodos de fazer e usar as mesmas é provida fibra de polpa kraft modificada com propriedades únicas. a fibra modificada pode ser uma fibra branqueada kraft modificado que é quase indistinguível da sua contrapartida convencional, excepto que tem um baixo grau de polimerização (dp). os métodos para fazer a fibra modificada e produtos produzidos a partir dela são também fornecidos. o método pode ser, de um processo de tratamento de uma etapa ácida catalisada de peróxido de ferro que podem ser incorporados em uma única fase de um processo de branqueamento multi-fase. os produtos podem ser matérias-primas, matérias-primas químicas celulose microcristalina celulose, polpas de felpa e os produtos feitos a partir deles. 1/1
