How does a pulp mill diagester work?
A pulp mill digester is a pressure vessel used in the pulping process to break down wood chips into cellulose fibers. It operates by cooking the wood chips in a chemical solution, typically consisting of sodium hydroxide and sodium sulfide, at high temperatures and pressures. This process, known as alkaline pulping or kraft pulping, removes lignin and other non-cellulosic components, transforming the wood into a slurry of cellulose fibers. After digestion, the mixture is processed further to separate the fibers from the spent liquor for subsequent washing and bleaching.

How are cellulosic manmade fibers identified?
The fibers, when made into fabrics, are identified by generic classifications that were established by the Textile Fiber Products Identification Act of 1960, and generic names were assigned by the Federal Trade Commission (FTC).
What does the Organic Fibers--Noncellulosic industry consist of?
Establishments primarily engaged in manufacturing noncellulosic, or synthetic, fibers comprise the manmade organic fibers industry.
Difference between a cellulosic manufactured fiber and a synthetic manufactured fiber?
Cellulosic manufactured fibers are derived from natural sources like plants (e.g., cotton, bamboo). Synthetic manufactured fibers are man-made fibers produced from chemicals and materials like petroleum (e.g., polyester, nylon). Cellulosic fibers have a more eco-friendly production process compared to synthetic fibers, which are typically non-biodegradable.
