Page "Lyocell" Paragraph 4

Hardwood logs are chipped into squares about the size of postage stamps.

The chips are digested chemically, to remove the lignin and to soften them enough to be mechanically milled to a wet pulp.

This pulp may be bleached.

Then it is dried into a continuous sheet and rolled onto spools.

At this stage, it has the consistency of thick posterboard paper.

The roll of cellulose weighs some 500 lb ( 227 kg ).

The waste liquor may be reworked to produce tall oil, used to make alkyd resins.
