Abstract
Procedimiento para la fabricación de papel de peso ligero, con elevada rigidez y elevado volumen, en especial para utilizarse como papel de impresión, papel de escribir y papel de oficina en máquinas de oficina y copiadoras, caracterizado porque, antes de la formación de hojas, se disminuye la elasticidad de las fibras de celulosa en que consiste al menos en parte el papel, para lo cual se someten primero las fibras de celulosa que han de ser modificadas en su elasticidad a un tratamiento de reacción con sustancias que tienen efecto reticulante y se añaden, en una segunda etapa del procedimiento, polímeros de ,alto peso molecular que contiene grupos hidroxilo y/o amino, y a continuación de ello eventualmente después de la adición y mezclado de fibras de celulosa no tratadas, se forma la hoja de papel de manera conocida.
