As soon as household goods began to appear on the market, paper towels occupied a certain place on it and confidently took root there. Now many consumers have a great demand. Paper towels have such diverse and surprising properties that many people have long abandoned fabric products. Disposable paper towels quickly and efficiently absorb moisture from hands and various surfaces. They are very hygienic and allow easy farming.
Paper towels are used not only at home in everyday life, but in places where large crowds of people are in places such as restaurants, clubs, offices, entertainment centers, shopping centers, in medicine and so on. Such a towel is hygroscopic, so it easily absorbs and removes fat, which means it has become a popular nakuhne.
Now our industry produces many varieties of paper products. These are napkins, paper, and paper napkins, and paper towels. That's about the latest products, and we'll talk.
In the toilet room of the house, the cinema, the office, the restaurant, the club and the cafe, the food court and the kitchen can not do without the means by which you can quickly wipe the spilled water, dry your hands and solve other problems that occur in everyday life. There are situations when paper towels just do not replace.
Sometimes paper towels are irreplaceable and on production. Paper towels are perfectly fighting with many production problems. They perfectly remove fat, absorb oils, water and other contaminants that need to be removed from various surfaces.
Types of paper towels are divided into several categories:
- Towels for use in places where a lot of people collect;
- towels for use in everyday life.
Also distinguish paper towels by the way they are packaged and folded. They can be roll and sheet.
Often, to give out towels in public places, install special devices, which are called dispensers. Thanks to them, you can control availability, save paper consumption, create comfort for visitors and, of course, formalize a public place. These adaptations are suitable for both roll and sheet towels.
There are several ways to add paper towels:
- Sheet paper towels are a way of adding up C. This is the most common and widespread method of addition. Such products are best suited for high traffic areas and are excellent for those places where standard hygiene requirements apply.
- Sheet paper towels are a way of adding V-ZigZag. Such towels are usually used in places with medium and low traffic.
- Paper towels In sheets - the method of addition Z. With this method of addition, towels appear from the dispenser one at a time. There are several advantages to packing:
- the next towel is not spoiled by dirty and wet hands;
- each towel ready for use;
- consumption can be controlled;
- special attention is given to hygiene. Such towels can be used in places where hygiene is required.
- Paper towels - a way of adding W. With this form of addition, the towels are perforated and come out one unfolded form. Such towels also have a big advantage - they can be used in places with high-hygiene.
In addition to those towels that are packed in piles, paper towels are already firmly entrenched. Paper towels in rolls are well suited to wipe the surface, remove the spilled liquid and corny dry the wet mackerels. Roll towels can be simple unwinding and with a central hood.
Now the producers produce sheet paper towels of various shapes. They can be oval, figured, round, square and any other performance. They also differ in smoothness, embossing, multilayeredness, single-layeredness, chromaticity. Each person can pick up paper towels for himself, but he has to pay attention to quality.
Quality indicators
The most important indicators of the quality of paper towels are density and initial strength. If you get a towel, and it dissipates in your hands or it is too soft or not tight, then it will be problematic to use it.
There is another indicator of quality: it is the ability to absorb liquid efficiently and quickly, while remaining durable even in the wet state. After absorbing moisture, the paper towel should not tear to pieces in your hands and leave wet fibers on the surfaces that you will process.
Paper towels are produced from waste paper or primary pulp. Products originating from the primary pulp are very durable, absorb excellent, and pleasant, soft feel. Often, these are more expensive options, which have more than one layer, perforation. They cost an order of magnitude higher than paper towels, which are made from recycled paper - recycled materials.
When the towel is made from cellulose, then a special technology is used to glue the product in a number of layers. It is clear that the more layers, the better, lush and stronger the towel.
Technology of production of izmakulature towels
Waste paper, which comes into production, is cleaned of all kinds of foreign impurities and impurities. Purified waste paper is sent to the first stage of production-milling.
This is a crushing machine, which works without interruptions, and there is a constant supply of paper and water. Then the crushed mass is passed through a sieve and sent to an intermediate tank, from where it is pumped to the rinsing tank.
Duration of washing will last depending on the color of the paper mass - this will further determine the price and quality of the towels. The water in which the waste paper was washed is drained into the sewer. The washed mass is transported through a fine grinding mill to the storage tank. And from there the water and paper pulp is pumped into the pressure tank.
After that, the suspension is sent to the concentration regulator, in which it is all mixed with water before the concentration of 0.5%. After that, the mass is poured onto the mesh table, where the paper is made.
The paper machine consists of an inlet device, a mesh table, a press section, a first dryer, a second drying and rolling.
Grid table is needed in order to filter the suspension through a fine nylon mesh, which at the same time serves as a transport tape. There are register rollers for the support. With the help of press cloth the mesh starts to move. Water that passes through the mesh is sent to a tank for circulating water. From there it is taken by a centrifugal pump for reuse. After that, the paper mass lies on the grid with a uniform layer, after which it is removed by the press felt.
Now the first drying drum, which is made out, removes the compacted pulp from the cloth. The temperature of the drying drum is approximately 110-115 degrees, it is heated by hot steam at a pressure of 0.7 kgf / cm2. The speed of rotation of the drum is 10-13 rpm.
When the future paper towels are on the drum, they are dried to a moisture content of 30-40%. Then, using a scraper blade, a continuous tape removes a layer of paper from the drying drum. After that, the paper is conveyed back to the drying drum for final drying.
The conveyor of the machine that produces paper towels is made so that 80% of the length of the drying drum is pressed against the mesh. Thus, the paper tape is clamped between the mesh, which moves and the drying drum. Thus, the towels dry out before the end. Dry paper cloth is wound on the bobbins on the sleeve. After that, towels are cut, perforated and packaged.
