Swelling and dissolution mechanisms of natural cellulose fibres [PDF]
, 2007 One of the limitations to the use of cellulose is the difficulty involved in the processing and fabrication because of the specific structure of the fibres. In most cases, cellulose cannot be used in its natural form. It has to be dissolved. The focus of
