Cellulose, commonly known as cellulosic fibers are fibers that are created by dissolving cellulose or wood pulp, which is shaped, precipitatedand regenerated. They are extracted from starch like carbohydrates from linters, wood, cotton fibers, glass, rubber and metals. Cellulosic fibers finds its wide applications in a varied range of fabrics including cotton, sisal, ramie, linen and hemp.
Cellulose is a complex form of polymer made of several hundreds of glucose molecules. These polysaccharides link the glucose molecules in a straight chain structure which is different from other complex carbohydrate molecules and starch.The special structure makes it stronger and as a result, enzyme produced in the bodies of animals cannot break it down into its constituent glucose molecules.
Cellulosic fibers are broadly categorised into natural and manufactured cellulosic fibers. Natural cellulose fibers are formed from a part of the original plant and prepared with minimal processing. The parts of the plants that are not used for production of fibers are usually separated and the strong hydrogen bonding cause them to form cellulose fibers which are insoluble in water. On the contrary, in case of man-made fibers, the parts of the plant are processed into a pulp after which they undergo the same processes as synthetic fibers.
Cellulosic fibres are known to have a great ability to withstand mechanical stresses and therefore, it is found to be widely used in the textile industry. Besides, it is excessively used in different types of filtration processes. Compared to other fibers, cellulosic fibers are found to have low density and cost.Also, they are recyclable and biodegradable which makes it a wonderful substitute for glass fibers in the production of composite materials. These are the advantages that have makes cellulosic fibers popular and trigger its widespread use in various industries besides the textile industry.
