What is cellulose Sponge?

Who was the first to invent cellulose sponge

In 1946 three of the engineers-Gerald “Red” Murray, Chester “Chet” Hardt and Jack Bitzer-left DuPont in Buffalo to establish an organization to make sponges for the consumer market. They named the company O-CEL-O after the chemical formula for their sponge: Oxygen-Cellulose-Oxygen.

How do Cellulose Sponges are manufactured?

Cellulose sponges are hemp fibers as well as sodium sulphate crystals softeners and wood pulp (cellulose). Flax and other ingredients are added to certain formulations to increase durability, chemical resistance, or other desirable qualities. The process of making cellulose sponges starts with huge rigid pieces of Cellulose. The sheets are then combined with softeners in huge containers of water to make an slurry of jelly-like consistency that is later mixed with sodium sulfurate Crystals, dye.

The steps involved to make the cellulose sponge are described below.

1. The cellulose used in the production of sponges is delivered to the factory in huge rigid sheets. The workers take the sheets and then soak them in a bath of water that is mixed with chemical softeners. The cellulose softens and becomes jelly-like. Workers then load this cellulose in a rotating mixer that is a huge moving drum of steel. Workers then add sodium sulphate crystals and cut hemp fibers, dye, and then close the mixer. Mixer is programmed to spin in a churning motion, and then stirs the ingredients until they’re completely incorporated.

2. After mixing workers pour the material into a rectangular mold, which could be as tall as 2 feet (61 centimeters) in height, 2 feet (61 centimeters) wide and 6 feet (1.8 meters) long. This mold gets heated and the cellulose mixture is cooked. While it cooks, sodium sulphate crystals melt and are able to drain through holes at the bottom of the mold. The melting creates the distinctive pores in the final sponge. The dimensions of the pores are dependent on the dimension of salt sulphate crystals. A coarse sponge to wash a car for instance, is created of coarse crystals. On the other hand, one of the finer kind used to apply makeup uses extremely small crystals. The cellulose mixture gets cooked, it cools and it turns into a hard porous block.

3. The sponge block is submerged in a puddle of bleach. The bleach removes dirt and impurities. It it also improves the color. Then the sponge is washed by soaking it in water. Further washings alter the texture, making sponge more flexible. The sponge is then left to dry so that it is ready to be cut.

4. Some companies make the sponge, cut it and wrap it in their own packaging. Other manufacturers produce the raw blocks of sponge before selling them off to an firm called the converter. The converter cut the sponges to meet the requirements of its clients and handles the distribution and packaging. In the original manufacturing plant or at the converter, workers cut sponges with an automated cutter. They put each huge rectangular piece of sponge into the machine, which cuts it into the size they want. Since this sponge is rectangular in shape, it is able to be cut into smaller rectangles and there is minimal or even no leftover.

5. Many household sponges feature an textured plastic scouring pad connected to the other side. The scouring pad is attached by laminating process, following the cutting of the sponge. The scouring pad, that is cut to the same dimensions that the sponge is then affixed to the sponge using a laminating.

Where we can use cellulose sponges

Cellulose sponge is a sponge product made of coniferous wood and other cotton fibers. Because it is made of natural wood, it can be 100% degraded naturally and will not cause damage to the environment.

Because of its unique characteristics, it was originally used in daily life as a new type of green cleaning material. In addition, it has good water absorption and features, and perhaps it has played an essential environmental protection role in many fields.

What are the applications of cellulose sponges?

Because cellulose sponge is composed of one material. The main part of the franchise is the change in appearance and application direction.

Daily cleaning and car cleaning: due to its excellent water absorption as well as high-temperature resistance. It can sterilize inside of the microwave, killing 95% bacterias or more.

Beauty salon: It is an indispensable cleaning tool for professional technicians in beauty salons. It can effectively remove stains on the skin or remove oil.

Beauty: It can be convenient for consumers to take care of daily and remove the mask. It can be adapted to different skin types without causing allergies.

Literature and art teaching materials: professional teaching aids for education and training can be made.

Electric soldering iron: can be used to clean the high-temperature soldering iron tip.

Laboratory: It can be used for cultivation and conducting cultivation tests.

Promotional items: The logo can be printed on the air-dried and processed sponge as a slogan.

How do you use a cellulose sponge?

After taking out the sealed cellulose sponges from the vacuum packaging bag or the heat-sealed bag, Rinse away the humectant residue of the sponge before your first use.

The sponges can be used according to your different needs. For example, wipe the stains on the object’s surface, absorb the moisture remaining on the desktop, or it can be used as a laboratory for microbial cultivation. You can even use it to cultivate plants.

After using, you can put the sponges in a ventilated place or hang them up. They can be quickly dried in natural air, thereby eliminating the nourishment of bacteria and avoiding health hazards to the human body. Re-immerse it in water at the beginning of the next use. It can be reused when wet.

How long can they be stored generally?

The standard sealing method is shrinking film or heat pressure sealing bag. There is currently no accurate scientifically recorded storage time. For the well-sealed sponges, for example, some products in the UC Sponge sample room have even been used for four years, except that the color is slightly oxidized, and there is no change in use. Therefore, this kind of sponge is very suitable for long-term storage and warehouse-type sales.

What should I do with the cellulose sponge after use?

The sponges may crack or become thinner after repeated use. Or damaged under extreme conditions of use, you can discard it at this time. Don’t worry; they will not cause any harm to the environment. If you smash it into smaller pieces, it will be more conducive to its natural degradation.

Is there degradable packaging suitable for cellulose sponges?

Of course, full composite organic bags made of corn starch or other PLA materials on the market can be naturally degraded. If you have high requirements for environmental protection or carbon emissions, we can provide corresponding packaging solutions.

How to clean cellulose sponges

Surface stains that are easier to clean can be washed with running water. For sponges that contain greasy dirt, you can use detergent or other auxiliary cleaning agents to remove them.

Can a microwave oven sterilize it?

According to relevant laboratory test data, short-term high temperature and ultraviolet disinfection can kill 95% of the bacteria that cover the sponge’s surface and harm the human digestive tract, such as Escherichia coli and Staphylococcus.

Are there disadvantages to cellulose sponges?

Although its original material-cellulose fiber, is 100% naturally degradable, it will cause particular environmental pollution during its production process. This is why very few countries and regions can have suitable foaming places.

The cellulose sponge block also has a certain proportion of humectants and preservatives for long storage, which must be washed many times when used for the first time, especially in direct food contact.

What is the difference between you and North American suppliers?

There are very few foaming plants for natural cellulose sponges in the world. Means fabrication manufacturing plants are not many. North American suppliers and ours use the same raw material supply companies. The main difference lies in processing costs and delivery timeliness. From these perspectives, we are more competitive. 

How to calculate the price of cellulose sponges?

Except for injection molded products, most sponge materials calculation use square or cubic unit prices to calculate costs. For compressed sponges, additional mold fees are required due to the processing of knife molds. Compared with overseas suppliers, we only charge About 5/1 of their tool costs.
