Abstract

a presente invenção refere-se a métodos de formação de celulose reticulada que incluem misturar um agente de reticulação com fragmentos de fibra de camada de celulose compostos de fibras de celulose ligadas por hidrogênio e que têm um teor de sólidos de cerca de 45 a 95% para formar uma mistura substancialmente homogênea de fibras de celulose individualizadas, não reticuladas, secar a mistura resultante até 85 a 100% de sólidos, então, curar a mistura seca sob condições eficazes para reticular as fibras de celulose. alguns dentre tais métodos podem incluir fragmentação de uma camada de fibra de celulose para formar os fragmentos de camada. os sistemas incluem uma unidade de mistura (tal como um misturador de alta consistência), configurada para formar, a partir dos fragmentos de camada e um agente de reticulação, uma mistura substancialmente homogênea de fibras de celulose individualizadas, não reticuladas, e a partir de um agente de reticulação, em condições do ambiente, uma unidade de secagem para secar a mistura substancialmente homogênea até uma consistência de 85 a 100%, e incluem uma unidade de cura para curar o agente de reticulação, a fim de formar fibras de celulose reticuladas curadas e secas.
