pulping
The process of reducing cellulosic raw materials,
e.g., pulpwood, rags, straw, esparto, reclaimed
papers, etc., to a condition suitable for further
processing into paper materials, or for chemical
conversion into some other cellulosic product.
Pulping may vary from a simple mechanical action
to complex digesting sequences and may be done in
batches or by means of continuously operating
equipment. (17 , 72 , 320 )
