With increasing awareness among people about hygiene and cleaning the demand for the tissue paper has been increasing. These products are widely used in homes, hospitals, hotels, restaurants, and beauty parlours, among other places. The tissue paper industry has a large market potential due to its high consumption rate.

Tissue paper manufacturing entails producing end products such as tissue rolls, wipes, napkins, and paper towels from the initial raw material known as Jumbo tissue rolls made from virgin wood pulp or recycled paper. These large paper rolls were eventually cut into various types of tissue paper using specialized equipment and sold in the market.

The above two different types of tissue paper can be summarized as follows: &#;

Consumer Tissue Papers: Simply put, consumer tissue papers are those that are primarily used at home. In other words, consumer tissue papers are utilized in the home.

Industrial Tissue Papers: Another name for commercial tissue paper is industrial tissue paper. These are primarily used for napkins, facial tissues, paper towels, and toilet paper. As a result, these are used in places such as hotels, parties, homes, restaurants, offices, and beauty salons.

Market Research:

Thorough market research is critical to the success of any business. It provides critical insights for your business and gives you an idea of how to operate the unit, how much investment is required, and how well your products can be marketed, and what marketing channels can be planned at this stage, among other things.

Sourcing of raw material

The procurement of raw materials is one of the most important tasks in the tissue paper manufacturing industry. Plants used in production are large in size and thus relatively expensive. Consumers prefer high-quality products, but if raw material prices are high, finished product prices will be high as well. As a result, finding low-cost high-quality products is critical.

Machinery and Equipment:

The machinery and equipment needed are entirely dependent on the volume of business you intend to conduct. Band saw cutter, core making machine, cutting machine, winding machine, perforating machine, and embossing machine are examples of machinery. You can choose the appropriate machine once you have the product&#;s or products&#; precise blueprint.

Once you have the finished product, you must figure out how to sell it and turn it into money. For more assistance, contact Ultracare as they are best paper tissue manufacturers & tissue paper exporters in UAE!

The next step is the Formation -

From a layman&#;s perspective if I see a sheet with a patchy sheet formation and with pinholes amongst others, I would be reluctant to buy the product a second time. Needless to say it would also be really hard to run on the converting machine and the functionality of the paper would be low. So the Formation is very critical! The formation in modern day machines happens using a roll former! In the past this used to take place using a plain breast roll on a fourdrinier section, moved on to a Suction breast roll, on to a twin wire former or a roll forming concept. The main difference in the same was:

Fourdrinier Machines

Twin Wire Machines

Most used in the 60&#;s and 70&#;s

Used from the 70&#;s till date

Difficult to operate

Easy to operate

High tensile ratio &#; Since these machines were based on the fourdrinier concept these machines had a very high MD tensile strength

Improved sheet quality

Speed limitations of &#; m/min

No speed limitations at the wet end of the machine. The limitations come on the drying end.

A beautiful video by the PaperClassroom on formation please see the below clip:

Moving on the twin wire concept there are three different concepts:

1. S &#; wrap
2. C &#; wrap
3. Crescent Former

Crescent former is the most common forming roll type used as the forming happens directly on the felt, the machine length is much shorter as well as it is cheaper and easier to use, resulting in a better product! The crescent former has many other benefits in terms of energy, transfers and machine parts requirements amongst others.

The main objective in the former is to achieve:

1. The obvious first: a good formation
2. Drainage to be uniform across the deckle
3. Able to transfer the sheet to the press section without any fiber loss

If your formation at the wet end is not even or good, you will have issues downstream in multiple avenues:

1. Poor formation leads to poor down stream fiber formation resulting in low drainage and also drying would be uneven
2. Creping will be effected
3. There will be compromises in the strength and softness of the tissue!

Formation can be influenced by a variety of factors including the types of fibers used and the consistency of the fibers. As covered in the refining section, formation is greatly affected by the refining. However if you over refine the fibers, the fibers might not bond, resulting in formation issues. The headbox design and flow rate, can also effect the formation along with the drainage length and the wet end chemistry.

The principal in brief:

As the pulp slurry falls on the fabric from the water jets within the head-box, the breast roll uses a forming fabric to press the slurry against the felt, avoiding the need to transfer the paper to a felt later in the process. The initial drainage takes place at this stage around the forming roll, with the wire tension determining the amount of the drainage. The pressure at the forming roll is calculated as under:

The most common forming roll diameter is 1.5 meters, and the same is sufficient to make tissue up to 40 GSM. However the machine slows down on heavy weights as the drainage pressure needs to be increased and hence retain higher tension. The machine generally functions at m/min, and on the middle basis weights from 13 &#; 2 GSM the machine attains its design speed of m/min. The drainage pressure is important because if the paper is not dewatered at the initial stage, we might need to use more energy at the Yankee to achieve a finished moisture content of 5-6%! The same can also effect the inter fiber bonding and other properties.

The jet speed from the headbox to the felt and the speed of the machine also influences the properties of the paper primarily influencing the tension in the paper.

Now that you know how the formation of the paper begins, it&#;s a good time to talk about the deckles and trim. The common finished paper deckles in the industry are mm, mm and mm. Whilst there are a range of other sizes these are the most common sizes!

A deckle is the breadth of the web across which the paper is made on the forming roll whilst the trims, are the excess that are cut during the manufacturing process to ensure quality of the finished product and to reuse the same in the fiber input line!

We generally have three widths on a paper machine:

1. Wire Width: The entire width of the felt fabric covering the forming roll. The same is generally greater than the headbox width
2. Web Width: The width on which the fibers fall on the felt from the headbox. As pulp is a slurry the web width is also slightly greater than the width of the head box
3. Trimmed Width: The edges on the web are trimmed in the wet end, as by principal the bonding is not expected to be the best and the paper will be weak and will be of no use. In order to not expel energy to dry the trim and later trim in the dry end, a part of the web is trimmed. The remaining deckle of the paper is what is consumable. Although the paper is again trimmed in the dry end, either during converting or during the rewinding process.

Let us take the example of a finished machine deckle of MM to explain the widths better:

1. The headbox of the machine would be designed at mm
2. The Wire Width would be mm
3. The Paper Width on the wire would be mm
4. The trim on the forming roll would be 54.5 mm on either side
5. The trimmed width or usable part of the paper would be mm with 3mm would be uneven from the trim at the forming roll

This vastly completes the wet end of the paper. The paper is then carried from the wet end on the felt to the press section. The press section transfers the paper from the felt to the yankee for the final stage of drying. The press section is also a cheaper method to drain water from the sheet rather than using energy to further dry the paper.
