CHAPTER 25 

 Pulp and Paper 



Pulp, i.e., fibers separated by mechanical or ciiemical methods from vegeta- 

 ble material (usually wood) can be formed, usually with the aid of water, into 

 cohesive sheets of paper. 



The technology of pulp and paper manufacture is complex, the products 

 diverse, and the literature describing processes and products very extensive. 

 This chapter involves only a brief overview, emphasizing products from hard- 

 woods. Readers needing more information are directed to the following 

 references.
