Alpha cellulose from cotton linters

Introduction of alpha cellulose product and how to separate it

Product Introduction: Cellulose is the constituent of the cell wall of plants. This compound was first considered in 1838 AD. It can be said that cellulose is present in all agricultural wastes and is composed of 3 parts: alpha-cellulose, beta-cellulose and gamma-cellulose. These 3 models of cellulose are possible with a profit of 5.17%, so that beta-gamma cells are precipitated at a profit of 5.17% at a temperature of 25 ° C, and what remains is alpha-cellulose.

Active units in the factory

Production unit: All production work, including cleaning of cutter 2, baking, painting and packaging is the responsibility of this important unit, which is composed of experienced, fully experienced and professional personnel ...

Applications of alpha cellulose

As mentioned before, alpha cellulose is used in various industries, some of which are mentioned: 1- Production of CMC (carboxymethylcellulose): Carboxymethylcellulose, which is widely used in both industrial and food grades ...

Alpha Cellulose Process

In general, the production process in Linterpack factory is divided into 2 parts: 1- Physical process 2- Chemical process _ Physical process includes separation of foreign objects such as: soil, cotton seeds, stone, wood, which are divided into two methods: dry separation and wet separation It is done by the most advanced devices and is fully mechanized and automatic.

Application of alpha cellulose

Alpha cellulose is used in various food, pharmaceutical and military fields.

In order to purify from the mechanical treatment steps

Rinsing with hot water and finally purification with soda chemical process is used in three levels of sodium hydroxide concentration (40 g / l, 30 g / l, 20 g / l)

Alpha cellulose determination test

The results of alpha cellulose determination test showed that at concentrations of 20 g / l and 30 g / l, respectively, 0.99, 12.99 and 40 g / l sodium hydroxide obtained the highest alpha purity (23.99)

X-ray diffraction information (XRD)

Showed that the purified fibers in alkali have a pattern related to type 1 cellulose and mechanical and chemical processes have not changed the structure of cellulose.


The combined method in this research reduces the chemical and environmental pollution of the production of this product and high quality products are obtained. By optimizing the production conditions, an important step can be taken in the production of high quality alpha cellulose.

Highly Powerful and Useful Website Functionality
Types of cellulose

Cellulose nanocrystals (CNC)

Is a new group of cellulosic materials that has been widely used in various fields of research over the past two decades. These nanoparticles are often prepared by acid hydrolysis of cellulosic compounds such as wood, cotton, starch, etc.

Production of alpha-cellulose and carboxymethylcellulose from cotton waste

The production of alpha cellulose and carboxymethylcellulose (CMC) materials, which have a high economic value, will be treated from cotton waste. To produce alpha cellulose, cotton waste in a solution of 30 g / L sodium hydroxide for 2 hours at 130 ° C It was cooked. Then 4% oxygenated water was used to bleach the fibers.

Dimensions of cellulose

Cellulose consists of units with a diameter of 35 angstroms, which are called primary filaments. This diameter is often true but not certain. For example, in some samples, such as cellulose, the algal wall is 300 angstroms, and in the mucilage composition of some fruits, it is only 1 angstrom.

What is a craft?

Paper mills that have facilities that can produce raw materials and pulp directly from wood and the paper they produce has a very good strength and quality. This sheet is called a kraft.

Dough production unit from carton waste

In the pulp production unit, first the inclusions or waste of the carton enters the hydropulper tank by the conveyor and on this conveyor it enters the hydropulper tank and on this conveyor some impurities are removed from the dough at this stage.

Production line or paper machine

Paper production. The process of paper production is as follows: cellulose fibers are placed in water to absorb moisture and become swollen and soft; They are then spread on a fine wire mesh to absorb the water in the fibers and the wet strands sit on the surface of the mesh and become a board.
