Microcrystalline cellulose (MCC) is a term for refined wood pulp and is used as a texturizer, an anti-caking agent, a fat substitute, an emulsifier, an extender, and a bulking agent in food production. [1] The most common form is used in vitamin supplements or tablets.
Curran is based on microcrystalline nanocellulose particles, [21] with properties similar to both carbon fibre-based composites and glass fibre composites. [9] Its composition is around 80% root vegetable fibre and 20% oil. [15] Its cellulose content is approximately 20%. [22] Curran composites have a tensile strength of 5 gigapascals. [19]
Nanocellulose is a term referring to a family of cellulosic materials that have at least one of their dimensions in the nanoscale.Examples of nanocellulosic materials are microfibrilated cellulose, cellulose nanofibers or cellulose nanocrystals.
The advantage of this process is the saving of shredding, as the cellulose layers can be added directly into the stirred tank. Acetylating the cellulose: In the commercial production of cellulose acetates, the acetic acid process or the methylene chloride process are usually used for acetylation. In acetic acid processes, the pre-treated ...
This, along with the ability of the kraft process to accept a wider variety of types of wood and produce stronger fibers [4] made the kraft process the dominant pulping process starting in the 1940s. [3] Sulfite pulps now account for less than 10% of the total chemical pulp production [3] and the number of sulfite mills continues to decrease ...

Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite ...
