What is cotton pulp?
cotton pulp is a basic product used to produce a range of products such as high quality paper and filter materials. For these applications, cotton -based stock exchanges are preferred because they do not contain any of the acids and lignin present in wooden pulp. The pulp is mainly made of cotton lines harvested from cotton plants or cotton waste such as rags and off-cuts. The process of wrapping cotton includes "cooking" finely induced cotton fibers with various chemicals and water. During this process, the porridge on the pulp is subjected to several cleaning degrees before creating in the finished or half sheets designed for further processing by end users.
Cotton is one of the purest forms of cellulose found in nature. Cotton pulp without all lignin, acid and less contaminants common to wood pulp, making the products more stable, more reliable and more robust. These properties cause the paper to produce from cottonNo Far more desirable as the bases of the archive stage for works of art and documents, because they degrade under artificial light so quickly. Cotton pulp, due to the lack of lignin, is also by its very nature brighter than wooden pulp, which requires very small whitening.
Most cotton pulp is made of cotton lines or rag waste. Linters are short, fine natural fibers that surround the seeds of cotton plants. Lanters are collected during the harvest of cotton boll and graduate to separate the fibers suitable for the production of cotton pulp. The waste of rag waste is generally any cotton fabric outside the slices from the production processes of textiles or clothing that would otherwise be intended for disposal. These rags can have a wide range of weights, sizes and colors, all suitable for the cotton pulp process if they are properly prepared.
The process of spraying cotton begins with sorting lineto remove any foreign contaminants or rag. Then the raw materials are finely chopped and placed in pressure VAT with water and various chemicals. The mixture is then "cooked" at carefully controlled temperatures and pressures, usually under the control of the computer, so that cotton fibers break into a porridge rich in cellulose. Once the cotton pulp achieves the desired consistency, it passes through several refining processes that remove all fine dirt and remaining contaminants.
After cleaning, cotton pulp is either pumped into storage channels, semifinals or processing into final products. The stored cotton pulp and semi -definitive or half stock are generally sold to end -producing non -promising users to create a number of high quality paper products. Half supply is produced by creating pulp into dense leaves, where suction is released and dried before packing in packaging for distribution.
