Higher-quality paper
- Chemical pulping uses the pulp produced from wood after it has been chemically digested to make fibers. Chemical pulping offers higher-quality paper than conventional mechanical pulping, but it also produces thinner pulp fibers and fewer of them.

Are chemical pulps stronger than mechanical pulps?
The main benefit of chemical pumping is that the pulp fibers produced are long and strong. These long fibers can be used to make much stiffer, stronger paper products. Chemical pulp is used for high-quality white paper and other quality paper products. Another reason why chemical pulping is sometimes preferred is its self-sustainability.

Advanced Pulp Washing and Drying: Effective washing removes residual chemicals and impurities, while optimized drying processes reduce energy consumption and improve pulp strength and consistency.
Kraft pulping has led the way in chemical pulping because it can make useable pulps from any type of wood, recovers energy and chemicals from used pulping liquor better than any other method, and consistently produces the strongest pulp.
While the regular chemical pulping it has been accomplished that there is steady progress in energy efficiencies and new types of pulping that incorporates additional methods in which there is usage of chemical as well as mechanical processes of separation.
Chemical pulping is the predominant process that is currently used around the world with the main objective of this pulping process being the efficient removal of lignin. The pros-and-cons of the three major chemical pulping processes of soda, sulfite and Kraft and their potential to act as pretreatment processes are discussed below. 2.1.1 Soda ...
Jan 3, 2021 · The pulping industry has for decades not developed new pulping techniques but rather improved the traditional chemical and mechanical pulping processes to enhance pulp yields and quality, as well as saving energy and chemical loading required for pulping.
The alkaline kraft process has become the chemical pulping method of choice because of advantages in chemical recovery and pulp strength. However, the formation of organic sulfides in the kraft process has caused environmental concern due to their escape as malodorous gases.
