rag pulp

Bankruptcy and lawsuit documents reveal how waterfalls powered mills that generated tens of thousands of reams a year, while owners tried to replace expensive rag pulp by grinding vats of asbestos, leather and seaweed instead.

That ancient world had no paper made in definite sizes from rag pulp.

This rag pulp, now called half stock, is kept in this receptacle until the water and liquor are thoroughly drained off, when it becomes a white and compact mass of fibers.

Chemical wood pulp of the best quality makes an excellent product, and is largely used for both print and book paper; it is frequently mixed with rag pulp, making a paper that can scarcely be distinguished from that made entirely from fine rags, though it is not of the proper firmness for the best flat or writing papers.

The pulp mill does nothing but bleach the rag pulp and prepare for the machines in the other mills; while the super-calendering mill gives the paper an extra finish when ordered.
