Chemical wood pulp
Paper pulp made from chemically treated wood fibers. Chemical pulp is produced by treating debarked, ground wood or chips with strong solutions to dissolve the lignin and hemicellulose. The undissolved cellulose fibers are washed, rinsed, sometimes bleached, then used to produce paper. The three main types of solutions used to make chemical pulp are:
- alkaline: caustic soda (soda process),
Synonyms and Related Terms
chemical pulp; woodfree pulp
Produces a pale blue-violet to red violet response to iodine-zinc chloride solution. Graff "C" stain can be used to distinguish types of chemical pulping and bleaching.
