Mixed cellulose fibres from timber and annual plants - by mixing long and short fibre material processed together

摘要

A mixed semi- or full cellulosic material is produced from wood and annual plants, for paper, carton, cellulose and viscose mfr. by reducing the annular plant matter into small particles before boiling, by chopping, cutting or crushing. The wood is reduced to chips as uniform as possible, with a thickness of 0.1 to 3 mm. These are mixed with the disintegrated annual plant matter. The two components are then boiled with the usual chemical additives to form cellulose. The process makes it unnecessary to handle the different types of fibre separately in distinct vessels. Small quantities of long fibred material can be mixed in with the short fibres from annual plants.
